Or simply:
view.getLayoutParams().width = 400;
view.requestLayout();
foreach($data as $value)
{
$value["transaction_date"] = date('d/m/Y',$value["transaction_date"]);
}
return $data;
I feel that one of the mentioned cons for "Handlebars" isnt' really valid anymore.
Handlebars.java now allows us to share the same template languages for both client and server which is a big win for large projects with 1000+ components that require serverside rendering for SEO
Take a look at https://github.com/jknack/handlebars.java
File -> Preferences -> Settings or just press Ctrl + , and search for spaces, then just deactivate this option:
I had to reopen the file so the changes would take effect.
Another option:
Replace the string delimiter with a single character, then split on that character.
string input = "abc][rfd][5][,][.";
string[] parts1 = input.Replace("][","-").Split('-');
You are setting the response headers after writing the contents of the file to the output stream. This is quite late in the response lifecycle to be setting headers. The correct sequence of operations should be to set the headers first, and then write the contents of the file to the servlet's outputstream.
Therefore, your method should be written as follows (this won't compile as it is a mere representation):
response.setContentType("application/force-download");
response.setContentLength((int)f.length());
//response.setContentLength(-1);
response.setHeader("Content-Transfer-Encoding", "binary");
response.setHeader("Content-Disposition","attachment; filename=\"" + "xxx\"");//fileName);
...
...
File f= new File(fileName);
InputStream in = new FileInputStream(f);
BufferedInputStream bin = new BufferedInputStream(in);
DataInputStream din = new DataInputStream(bin);
while(din.available() > 0){
out.print(din.readLine());
out.print("\n");
}
The reason for the failure is that it is possible for the actual headers sent by the servlet would be different from what you are intending to send. After all, if the servlet container does not know what headers (which appear before the body in the HTTP response), then it may set appropriate headers to ensure that the response is valid; setting the headers after the file has been written is therefore futile and redundant as the container might have already set the headers. You could confirm this by looking at the network traffic using Wireshark or a HTTP debugging proxy like Fiddler or WebScarab.
You may also refer to the Java EE API documentation for ServletResponse.setContentType to understand this behavior:
Sets the content type of the response being sent to the client, if the response has not been committed yet. The given content type may include a character encoding specification, for example, text/html;charset=UTF-8. The response's character encoding is only set from the given content type if this method is called before getWriter is called.
This method may be called repeatedly to change content type and character encoding. This method has no effect if called after the response has been committed.
...
After creating Set just convert it to List and get by index from List:
Set<String> stringsSet = new HashSet<>();
stringsSet.add("string1");
stringsSet.add("string2");
List<String> stringsList = new ArrayList<>(stringsSet);
stringsList.get(0); // "string1";
stringsList.get(1); // "string2";
Here is a example of embedding without an iFrame:

compare to regular iframe "embed" code from YouTube:
<iframe

frameborder="0"
allow="accelerometer; autoplay; encrypted-media; gyroscope; picture-in-picture"

Uncheck "Size Classes" checkbox works for me as well, but you could also add the missing constraints in the interface builder. Just use the built-in function if you don't want to add the constraints on your own. Using constraints is - in my opinion - the better way because the layout is independent from the device (iPhone or iPad).
Changing the memory_limit
by ini_set('memory_limit', '-1');
is not a proper solution. Please don't do that.
Your PHP code may have a memory leak somewhere and you are telling the server to just use all the memory that it wants. You wouldn't have fixed the problem at all. If you monitor your server, you will see that it is now probably using up most of the RAM and even swapping to disk.
You should probably try to track down the offending code in your code and fix it.
another way to create a data url from blob url may be using canvas.
var canvas = document.createElement("canvas")
var context = canvas.getContext("2d")
context.drawImage(img, 0, 0) // i assume that img.src is your blob url
var dataurl = canvas.toDataURL("your prefer type", your prefer quality)
as what i saw in mdn, canvas.toDataURL is supported well by browsers. (except ie<9, always ie<9)
Since so many people are referring to Raymond's talk, I'll just make it a little easier by writing down what he said:
The intention of the double underscores was not about privacy. The intention was to use it exactly like this
class Circle(object): def __init__(self, radius): self.radius = radius def area(self): p = self.__perimeter() r = p / math.pi / 2.0 return math.pi * r ** 2.0 def perimeter(self): return 2.0 * math.pi * self.radius __perimeter = perimeter # local reference class Tire(Circle): def perimeter(self): return Circle.perimeter(self) * 1.25
It's actually the opposite of privacy, it's all about freedom. It makes your subclasses free to override any one method without breaking the others.
Say you don't keep a local reference of perimeter
in Circle
. Now, a derived class Tire
overrides the implementation of perimeter
, without touching area
. When you call Tire(5).area()
, in theory it should still be using Circle.perimeter
for computation, but in reality it's using Tire.perimeter
, which is not the intended behavior. That's why we need a local reference in Circle.
But why __perimeter
instead of _perimeter
? Because _perimeter
still gives derived class the chance to override:
class Tire(Circle):
def perimeter(self):
return Circle.perimeter(self) * 1.25
_perimeter = perimeter
Double underscores has name mangling, so there's a very little chance that the local reference in parent class get override in derived class. thus "makes your subclasses free to override any one method without breaking the others".
If your class won't be inherited, or method overriding does not break anything, then you simply don't need __double_leading_underscore
.
Below input field I include additional view:
@include('input-errors', ['inputName' => 'inputName']) #For your case it would be 'email'
input-errors.blade.php
@foreach ($errors->get($inputName) as $message)
<span class="input-error">{{ $message }}</span>
@endforeach
CSS - adds red color to the message.
.input-error {
color: #ff5555;
}
This is a bit indirect, but it works very nicely. Get LiveWriter and install this plugin:
http://lvildosola.blogspot.com/2007/02/code-snippet-plugin-for-windows-live.html
Insert your code using the plugin into a blog post. Select all and copy it to Word.
It looks great and can include line numbers. It also spans pages decently.

For Spreedsheet + PHP 7, you must write instead of PHPExcel_Cell::columnIndexFromString
, \PhpOffice\PhpSpreadsheet\Cell::columnIndexFromString
. And at the loop is a mistake, there you must <
not work with <=
. Otherwise, he takes a column too much into the loop.
For complicated objects and when performance is not significant i use gson to serialize the object to json text, then deserialize the text to get new object.
gson which based on reflection will works in most cases, except that transient
fields will not be copied and objects with circular reference with cause StackOverflowError
.
public static <ObjectType> ObjectType Copy(ObjectType AnObject, Class<ObjectType> ClassInfo)
{
Gson gson = new GsonBuilder().create();
String text = gson.toJson(AnObject);
ObjectType newObject = gson.fromJson(text, ClassInfo);
return newObject;
}
public static void main(String[] args)
{
MyObject anObject ...
MyObject copyObject = Copy(o, MyObject.class);
}
The following worked for me: Just save as custom_shape.xml.

This solution will take a character vector of package names and attempt to load them, or install them if loading fails. It relies on the return behaviour of require
to do this because...
require
returns (invisibly) a logical indicating whether the required package is available
Therefore we can simply see if we were able to load the required package and if not, install it with dependencies. So given a character vector of packages you wish to load...
foo <- function(x){
for( i in x ){
# require returns TRUE invisibly if it was able to load package
if( ! require( i , character.only = TRUE ) ){
# If package was not able to be loaded then re-install
install.packages( i , dependencies = TRUE )
# Load package after installing
require( i , character.only = TRUE )
}
}
}
# Then try/install packages...
foo( c("ggplot2" , "reshape2" , "data.table" ) )
Another cross-browser approach based on above solution
function doScrollTo(to, duration) {
var element = document.documentElement;
var start = element.scrollTop,
change = to - start,
increment = 20,
i = 0;
var animateScroll = function(elapsedTime) {
elapsedTime += increment;
var position = easeInOut(elapsedTime, start, change, duration);
if (i === 1 && window.scrollY === start) {
element = document.body;
start = element.scrollTop;
}
element.scrollTop = position;
if (!i) i++;
if (elapsedTime < duration) {
setTimeout(function() {
animateScroll(elapsedTime);
}, increment);
}
};
animateScroll(0);
}
The trick is to control the actual scroll change, and if it is zero, change the scroll element.
I had the same problem for a long time. I solved it by running these two commands, first is to install second is to activate the env:
python3 -m pip install virtualenv
python3 -m virtualenv yourenvname
Note that I'm using python3
, you can change it to just python
if python3
fails.
Thanks.
If you want to rename full android package, this is the best way to do that:

I guess I misunderstood what was being asked. Re-re-reading, it looks like Tim's answer is what you want. Let me just add this, however: if you want to catch an exception from open
, then open
has to be wrapped in a try
. If the call to open
is in the header of a with
, then the with
has to be in a try
to catch the exception. There's no way around that.
So the answer is either: "Tim's way" or "No, you're doing it correctly.".
Previous unhelpful answer to which all the comments refer:
import os
if os.path.exists(fName):
with open(fName, 'rb') as f:
try:
# do stuff
except : # whatever reader errors you care about
# handle error
That's basically it. These are the methods I use to convert to and from Unix epoch time:
public static DateTime ConvertFromUnixTimestamp(double timestamp)
{
DateTime origin = new DateTime(1970, 1, 1, 0, 0, 0, 0, DateTimeKind.Utc);
return origin.AddSeconds(timestamp);
}
public static double ConvertToUnixTimestamp(DateTime date)
{
DateTime origin = new DateTime(1970, 1, 1, 0, 0, 0, 0, DateTimeKind.Utc);
TimeSpan diff = date.ToUniversalTime() - origin;
return Math.Floor(diff.TotalSeconds);
}
Update: As of .Net Core 2.1 and .Net Standard 2.1 a DateTime equal to the Unix Epoch can be obtained from the static DateTime.UnixEpoch
.

1-usual ctor, 2nd-function-like-ctor with temporary object.
Compile this source somewhere here http://melpon.org/wandbox/ with different compilers
// turn off rvo for clang, gcc with '-fno-elide-constructors'
#include <stdio.h>
class Thing {
public:
Thing(const char*){puts(__FUNCTION__ );}
Thing(const Thing&){puts(__FUNCTION__ );}
~Thing(){puts(__FUNCTION__);}
};
int main(int /*argc*/, const char** /*argv*/) {
Thing myThing = Thing("asdf");
}
And you will see the result.
From ISO/IEC 14882 2003-10-15
8.5, part 12
Your 1st,2nd construction are called direct-initialization
12.1, part 13
A functional notation type conversion (5.2.3) can be used to create new objects of its type. [Note: The syntax looks like an explicit call of the constructor. ] ... An object created in this way is unnamed. [Note: 12.2 describes the lifetime of temporary objects. ] [Note: explicit constructor calls do not yield lvalues, see 3.10. ]
Where to read about RVO:
12 Special member functions / 12.8 Copying class objects/ Part 15
When certain criteria are met, an implementation is allowed to omit the copy construction of a class object, even if the copy constructor and/or destructor for the object have side effects.
Turn off it with compiler flag from comment to view such copy-behavior)

If you want a straight redirect of all output to a file, try using *>>
:
# You'll receive standard output for the first command, and an error from the second command.
mkdir c:\temp -force *>> c:\my.log ;
mkdir c:\temp *>> c:\my.log ;
Since this is a straight redirect to file, it won't output to the console (often helpful). If you desire the console output, combined all output with *&>1
, and then pipe with Tee-Object
:
mkdir c:\temp -force *>&1 | Tee-Object -Append -FilePath c:\my.log ;
mkdir c:\temp *>&1 | Tee-Object -Append -FilePath c:\my.log ;
# Shorter aliased version
mkdir c:\temp *>&1 | tee -Append c:\my.log ;
I believe these techniques are supported in PowerShell 3.0 or later; I'm testing on PowerShell 5.0.
Because HTTP is stateless, in order to associate a request to any other request, you need a way to store user data between HTTP requests.
Cookies or URL parameters ( for ex. like http://example.com/myPage?asd=lol&boo=no ) are both suitable ways to transport data between 2 or more request. However they are not good in case you don't want that data to be readable/editable on client side.
The solution is to store that data server side, give it an "id", and let the client only know (and pass back at every http request) that id. There you go, sessions implemented. Or you can use the client as a convenient remote storage, but you would encrypt the data and keep the secret server-side.
Of course there are other aspects to consider, like you don't want people to hijack other's sessions, you want sessions to not last forever but to expire, and so on.
In your specific example, the user id (could be username or another unique ID in your user database) is stored in the session data, server-side, after successful identification. Then for every HTTP request you get from the client, the session id (given by the client) will point you to the correct session data (stored by the server) that contains the authenticated user id - that way your code will know what user it is talking to.
Apart from sp_who
, you can also use the "undocumented" sp_who2
system stored procedure which gives you more detailed information. See Difference between sp_who and sp_who2.
ok to resolve this First install dns for python by cmd using pip install dnspython
(if you use conda first type activate
and then you will go in base (in cmd) and then type above code)
it will install it in anaconda site package ,copy the location of that site package folder from cmd, and open it . Now copy all dns folders and paste them in python site package folder. it will resolve it .
actually the thing is our code is not able to find the specified package in python\site package bcz it is in anaconda\site package. so you have to COPY IT (not cut).
For both python3 and python2 you can use pyautogui
(pip install pyautogui
)
from pyautogui import press, typewrite, hotkey
press('a')
typewrite('quick brown fox')
hotkey('ctrl', 'w')
It's also crossplatform with Windows, OSX, and Ubuntu LTS.
Well, the code that renders the button enabled/disabled:
if(name.getText().equals("")) {
loginbt.setEnabled(false);
}else {
loginbt.setEnabled(true);
}
must be written in javax.swing.event.ChangeListener
and attached to the field (see here). A change in field's value should trigger the listener to reevaluate the object state. What did you expect?

Use a HTML parser like DOMDocument
and then evaluate the value you're looking for with DOMXpath
:
$html = '<img id="12" border="0" src="/images/image.jpg"
alt="Image" width="100" height="100" />';
$doc = new DOMDocument();
$doc->loadHTML($html);
$xpath = new DOMXPath($doc);
$src = $xpath->evaluate("string(//img/@src)"); # "/images/image.jpg"
Or for those who really need to save space:
$xpath = new DOMXPath(@DOMDocument::loadHTML($html));
$src = $xpath->evaluate("string(//img/@src)");
And for the one-liners out there:
$src = (string) reset(simplexml_import_dom(DOMDocument::loadHTML($html))->xpath("//img/@src"));

A tty
is a physical terminal-teletype port on a computer (usually a serial port).
The word teletype is a shorting of the telegraph typewriter, or teletypewriter device from the 1930s - itself an electromagnetic device which replaced the telegraph encoding machines of the 1830s and 1840s.
A pty
is a pseudo-teletype port provided by a computer Operating System Kernel to connect software programs emulating terminals, such as ssh, xterm, or screen.
A terminal is simply a computer's user interface that uses text for input and output.
These use pseudo-teletype ports however, their naming and implementations have diverged a little.
Linux mounts a special file system devpts on /dev (the 's' presumably standing for serial) that creates a corresponding entry in /dev/pts
for every new terminal window you open, e.g. /dev/pts/0
macOS/FreeBSD also use the /dev file structure however, they use a numbered TTY
naming convention ttys
for every new terminal window you open e.g. /dev/ttys002
Microsoft Windows still has the concept of an LPT
port for Line Printer Terminals within it's Command Shell for output to a printer.

Native C/c++ Files libstdc++.* from your Ubuntu are x86 (or x86_64) binaries but Android devices and emulators are ARM. Of course, this will not work anyway, even if you'll set correct soname. This is very naive way which leads nowhere. Android has very limited support of C++ meaning there is no exceptions, standard C++ library (including STL) and RTTI. If you need such functionality, use my custom NDK distribution from
http://crystax.net/android/ndk.php - it support full C++ features listed above.
Why is there error: undefined reference to '__cxa_end_cleanup' link error. Android stlport
time. Because there is no link to libstdc + +. A. So wrong.
Because it uses some static library, it is necessary to link the full libstdc + +. A. Can
http://crystax.net/android/ndk.php here to download the package
sources \ cxx-stl \ gnu-libstdc + + \ libs \ armeabi directory.
Android on its own libstdc + + support is limited, it must be linked to a complete libstdc + +. A the job.
Add file in Android.mk LOCAL_LDFLAGS = $ (LOCAL_PATH) / libs / libcurl.a \
$ (LOCAL_PATH) / libs / liblua.a \
`$ (LOCAL_PATH) / libs / libstdc + +. A`
And LOCAL_CPPFLAGS + =-lstdc + +-fexceptions

The root of the problem is that you are unknowingly using the Frame
class from the ttk
package rather than from the tkinter
package. The one from ttk
does not support the background option.
This is the main reason why you shouldn't do global imports -- you can overwrite the definition of classes and commands.
I recommend doing imports like this:
import tkinter as tk
import ttk
Then you prefix the widgets with either tk
or ttk
:
f1 = tk.Frame(..., bg=..., fg=...)
f2 = ttk.Frame(..., style=...)
It then becomes instantly obvious which widget you are using, at the expense of just a tiny bit more typing. If you had done this, this error in your code would never have happened.
CURL request by default is GET, you don't have to set any options to make a GET CURL request.
Use Vim:
diff /path/to/a /path/to/b | vim -R -
Or better still, VimDiff (or vim -d

vimdiff file1 file2 file3 file4
I have Archlinux with php 7.2, which has Curl integrated, so no amount of configuration voodoo would make Composer see ext-curl, that PHP could see and work with happily. Work around is to use Composer with --ignore-platform-reqs.
eg composer update --ignore-platform-reqs
Reference = https://github.com/composer/composer/issues/1426
cp -Rvn /source/path/* /destination/path/
cp: /destination/path/any.zip: No such file or directory
It will create no existing paths in destination, if path have a source file inside. This dont create empty directories.
A moment ago i've seen xxxxxxxx: No such file or directory, because i run out of free space. without error message.
with ditto:
ditto -V /source/path/* /destination/path
ditto: /destination/path/any.zip: No space left on device
once freed space cp -Rvn /source/path/* /destination/path/
works as expected
New introduction 2
In the previous version of macro "SaveEmailDetails" I used this statement to find Inbox:
Set FolderTgt = CreateObject("Outlook.Application"). _
GetNamespace("MAPI").GetDefaultFolder(olFolderInbox)
I have since installed a newer version of Outlook and I have discovered that it does not use the default Inbox. For each of my email accounts, it created a separate store (named for the email address) each with its own Inbox. None of those Inboxes is the default.
This macro, outputs the name of the store holding the default Inbox to the Immediate Window:
Sub DsplUsernameOfDefaultStore()
Dim NS As Outlook.NameSpace
Dim DefaultInboxFldr As MAPIFolder
Set NS = CreateObject("Outlook.Application").GetNamespace("MAPI")
Set DefaultInboxFldr = NS.GetDefaultFolder(olFolderInbox)
Debug.Print DefaultInboxFldr.Parent.Name
End Sub
On my installation, this outputs: "Outlook Data File".
I have added an extra statement to macro "SaveEmailDetails" that shows how to access the Inbox of any store.
New introduction 1
A number of people have picked up the macro below, found it useful and have contacted me directly for further advice. Following these contacts I have made a few improvements to the macro so I have posted the revised version below. I have also added a pair of macros which together will return the MAPIFolder object for any folder with the Outlook hierarchy. These are useful if you wish to access other than a default folder.
The original text referenced one question by date which linked to an earlier question. The first question has been deleted so the link has been lost. That link was to Update excel sheet based on outlook mail (closed)
Original text
There are a surprising number of variations of the question: "How do I extract data from Outlook emails to Excel workbooks?" For example, two questions up on [outlook-vba] the same question was asked on 13 August. That question references a variation from December that I attempted to answer.
For the December question, I went overboard with a two part answer. The first part was a series of teaching macros that explored the Outlook folder structure and wrote data to text files or Excel workbooks. The second part discussed how to design the extraction process. For this question Siddarth has provided an excellent, succinct answer and then a follow-up to help with the next stage.
What the questioner of every variation appears unable to understand is that showing us what the data looks like on the screen does not tell us what the text or html body looks like. This answer is an attempt to get past that problem.
The macro below is more complicated than Siddarth’s but a lot simpler that those I included in my December answer. There is more that could be added but I think this is enough to start with.
The macro creates a new Excel workbook and outputs selected properties of every email in Inbox to create this worksheet:
Near the top of the macro there is a comment containing eight hashes (#). The statement below that comment must be changed because it identifies the folder in which the Excel workbook will be created.
All other comments containing hashes suggest amendments to adapt the macro to your requirements.
How are the emails from which data is to be extracted identified? Is it the sender, the subject, a string within the body or all of these? The comments provide some help in eliminating uninteresting emails. If I understand the question correctly, an interesting email will have Subject = "Task Completed"
.
The comments provide no help in extracting data from interesting emails but the worksheet shows both the text and html versions of the email body if they are present. My idea is that you can see what the macro will see and start designing the extraction process.
This is not shown in the screen image above but the macro outputs two versions on the text body. The first version is unchanged which means tab, carriage return, line feed are obeyed and any non-break spaces look like spaces. In the second version, I have replaced these codes with the strings [TB], [CR], [LF] and [NBSP] so they are visible. If my understanding is correct, I would expect to see the following within the second text body:
Activity[TAB]Count[CR][LF]Open[TAB]35[CR][LF]HCQA[TAB]42[CR][LF]HCQC[TAB]60[CR][LF]HAbst[TAB]50 45 5 2 2 1[CR][LF] and so on
Extracting the values from the original of this string should not be difficult.
I would try amending my macro to output the extracted values in addition to the email’s properties. Only when I have successfully achieved this change would I attempt to write the extracted data to an existing workbook. I would also move processed emails to a different folder. I have shown where these changes must be made but give no further help. I will respond to a supplementary question if you get to the point where you need this information.
Good luck.

Take that back Debian includes symlinks via their alternatives system and it still cannot find the proper paths between HDF5 openmpi packages and mpi.h referenced in the H5public.h header.
This is how you can nest multiple bool queries in one outer bool query this using Kibana,
GET my_inedx/my_type/_search
{
"query" : {
"bool": { //bool indicates we are using boolean operator
"must" : [ //must is for **AND**
{
"match" : {
"description" : "some text"
}
},
{
"match" :{
"type" : "some Type"
}
},
{
"bool" : { //here its a nested boolean query
"should" : [ //should is for **OR**
{
"match" : {
//ur query
}
},
{
"match" : {}
}
]
}
}
]
}
}
}
This is how you can nest a query in ES
There are more types in "bool" like,

For current window, you can use this:
var hash = window.location.hash.substr(1);
To get the hash value of the main window, use this:
var hash = window.top.location.hash.substr(1);
If you have a string with an URL/hash, the easiest method is:
var url = 'https://www.stackoverflow.com/questions/123/abc#10076097';
var hash = url.split('#').pop();
If you're using jQuery, use this:
var hash = $(location).attr('hash');
This seems simpler to me
<li *ngFor="let item of list | slice:0:10; let i=index" class="dropdown-item" (click)="onClick(item)">{{item.text}}</li>

<li class="dropdown-item" (click)="onClick(item)" *ngIf="i<11">{{item.text}}</li>
</ng-container>

Actually torek told you already how to use the tools much better than I would be able to do. However, in this case I think it is important to point out something peculiar if you follow the guidelines at http://octopress.org/docs/deploying/github/. Namely, you will have multiple github repositories in your setup. First of all the one with all the source code for your website in say the directory $WEBSITE
, and then the one with only the static generated files residing in $WEBSITE/_deploy
. The funny thing of the setup is that there is a .gitignore
file in the $WEBSITE
directory so that this setup actually works.
Enough introduction. In this case the error might also come from the repository in _deploy
.
cd _deploy
git branch -a
* master
remotes/origin/master
remotes/origin/source
In .git/config
you will normally need to find something like this:
[core]
repositoryformatversion = 0
filemode = true
bare = false
logallrefupdates = true
[remote "origin"]
url = [email protected]:yourname/yourname.github.io.git
fetch = +refs/heads/*:refs/remotes/origin/*
[branch "master"]
remote = origin
merge = refs/heads/master
But in your case the branch master does not have a remote.
[core]
repositoryformatversion = 0
filemode = true
bare = false
logallrefupdates = true
[remote "origin"]
url = [email protected]:yourname/yourname.github.io.git
fetch = +refs/heads/*:refs/remotes/origin/*
Which you can solve by:
cd _deploy
git branch --set-upstream-to=origin/master
So, everything is as torek told you, but it might be important to point out that this very well might concern the _deploy
directory rather than the root of your website.
PS: It might be worth to use a shell such as zsh
with a git
plugin to not be bitten by this thing in the future. It will immediately show that _deploy
concerns a different repository.
You can also make use of FilesystemIterator
. It requires even less code then DirectoryIterator
, and automatically removes .
and ..
.
// Let's traverse the images directory
$fileSystemIterator = new FilesystemIterator('images');
$entries = array();
foreach ($fileSystemIterator as $fileInfo){
$entries[] = $fileInfo->getFilename();
}
var_dump($entries);
//OUTPUT
object(FilesystemIterator)[1]

Option 1:
Use pandas
dataframe plot (built on top of matplotlib
):
import pandas as pd
data = [1.5]*7 + [2.5]*2 + [3.5]*8 + [4.5]*3 + [5.5]*1 + [6.5]*8
pd.DataFrame(data).plot(kind='density') # or pd.Series()
Option 2:
Use distplot
of seaborn
:
import seaborn as sns
data = [1.5]*7 + [2.5]*2 + [3.5]*8 + [4.5]*3 + [5.5]*1 + [6.5]*8
sns.distplot(data, hist=False)
In the console just type these :
export ANDROID_HOME=$HOME/Android/Sdk
export PATH=$PATH:$ANDROID_HOME/tools
If you want to make it permanent just add those lines in the ~/.bashrc file
In order to avoid the black background when starting an activity already in the stack, I added

}
It's not possible to clear user history without plugins. And also it's not an issue at developer's perspective, it's the burden of the user to clear his history.
For information refer to How to clear browsers (IE, Firefox, Opera, Chrome) history using JavaScript or Java except from browser itself?
In Java 8, you can read a whole file, simply with:
public String read(String file) throws IOException {
return new String(Files.readAllBytes(Paths.get(file)));
}
or if its a Resource:
public String read(String file) throws IOException {
URL url = Resources.getResource(file);
return Resources.toString(url, Charsets.UTF_8);
}

This could not work because despite you are redirecting to new page all state and props are being manipulated on the dom or simply rendering to the previous page did not stop.
What solution I found
import {Redirect} from 'react-router-dom'
if (true) {
return <redirect to="/new-route" />
}
return (
<>
<render component />
</>
)
From the jQuery API Document
While JavaScript provides the
load
event for executing code when a page is rendered, this event does not get triggered until all assets such as images have been completely received. In most cases, the script can be run as soon as the DOM hierarchy has been fully constructed. The handler passed to.ready()
is guaranteed to be executed after the DOM is ready, so this is usually the best place to attach all other event handlers and run other jQuery code. When using scripts that rely on the value of CSS style properties, it's important to reference external stylesheets or embed style elements before referencing the scripts.In cases where code relies on loaded assets (for example, if the dimensions of an image are required), the code should be placed in a handler for the
load
event instead.
Answer to the second question -
No, they are identical as long as you are not using jQuery in no conflict mode.
If you're googling this, and don't want the event listener to be an attribute, use:
document.getElementById('my-select').addEventListener('change', function() {_x000D_
console.log('You selected: ', this.value);_x000D_
});
_x000D_
<select id="my-select">_x000D_
<option value="1">One</option>_x000D_
<option value="2">Two</option>_x000D_
<option value="3">Three</option>_x000D_
</select>
_x000D_
An alternative, more generic method;
from pandas import DataFrame
def move_columns(df: DataFrame, cols_to_move: list, new_index: int) -> DataFrame:
"""
This method re-arranges the columns in a dataframe to place the desired columns at the desired index.
ex Usage: df = move_columns(df, ['Rev'], 2)

other = [c for c in df if c not in cols_to_move]
start = other[0:new_index]
end = other[new_index:]
return df[start + cols_to_move + end]
I didn't think this was possible: I had to delete flutter folder and reinstall it from scratch!
An easy way to overcome this problem is to use 64 bit type
list = numpy.array(list, dtype=numpy.float64)
Looks like you are missing a leading slash. Perhaps try:
Scanner s = new Scanner(new File("/home/me/java/ex.txt"));
(as to where it looks for files by default, it is where the JVM is run from for relative paths like the one you have in your question)
I know it is an old question, but I just managed to do so without a pseudo child (but a pseudo wrapper).
If you set the parent to be with no pointer-events
, and then a child div
with pointer-events
set to auto
, it works:)
Note that <img>
tag (for example) doesn't do the trick.
Also remember to set pointer-events
to auto
for other children which have their own event listener, or otherwise they will lose their click functionality.
div.parent { _x000D_
pointer-events: none;_x000D_
}_x000D_
_x000D_
div.child {_x000D_
pointer-events: auto;_x000D_
}_x000D_
_x000D_
div.parent:hover {_x000D_
background: yellow;_x000D_
}
_x000D_
<div class="parent">_x000D_
parent - you can hover over here and it won't trigger_x000D_
<div class="child">hover over the child instead!</div>_x000D_
</div>

The answer provided by @DSM is simple and straightforward, but I thought I'd add my own input to this question. If you look at the code for pandas.value_counts, you'll see that there is a lot going on.
If you need to calculate the frequency of many series, this could take a while. A faster implementation would be to use numpy.unique with return_counts = True
Here is an example:
import pandas as pd
import numpy as np
my_series = pd.Series([1,2,2,3,3,3])
print(my_series.value_counts())
3 3
2 2
1 1
dtype: int64
Notice here that the item returned is a pandas.Series
In comparison, numpy.unique
returns a tuple with two items, the unique values and the counts.
vals, counts = np.unique(my_series, return_counts=True)
print(vals, counts)
[1 2 3] [1 2 3]
You can then combine these into a dictionary:
results = dict(zip(vals, counts))
print(results)
{1: 1, 2: 2, 3: 3}
And then into a pandas.Series
print(pd.Series(results))
1 1
2 2
3 3
dtype: int64

s.close()
server.py
import socket
s = socket.socket()
port = 12345
s.bind(('', port))
s.listen(5)
c, addr = s.accept()

while True:
rcvdData = c.recv(1024).decode()
print "S:",rcvdData

c.send(sendData.encode())

This should be the code for a small prototype for the chatting app you wanted. Run both of them in separate terminals but then just check for the ports.
I think I found what you are looking for since I was also looking for it.
You have to follow Pawel's steps and then go to the key that is "Cookie". This will open a submenu with all the cookies and it specifies their name, value, domain, etc...
Respectively the values are: Key, Value, Expiration Date, Domain, Path.
This shows all the keys for this domain.
So again to get there:
I used this and it works well:
string[] filePaths = Directory.GetFiles(Path.GetDirectoryName(dialog.FileName));
foreach (string file in filePaths)
{
if (comboBox1.SelectedItem.ToString() == "")
{
if (file.Contains("c"))
{
comboBox2.Items.Add(Path.GetFileName(file));
}
}
}
In terms of coding, a bidirectional relationship is more complex to implement because the application is responsible for keeping both sides in synch according to JPA specification 5 (on page 42). Unfortunately the example given in the specification does not give more details, so it does not give an idea of the level of complexity.
When not using a second level cache it is usually not a problem to do not have the relationship methods correctly implemented because the instances get discarded at the end of the transaction.
When using second level cache, if anything gets corrupted because of wrongly implemented relationship handling methods, this means that other transactions will also see the corrupted elements (the second level cache is global).
A correctly implemented bi-directional relationship can make queries and the code simpler, but should not be used if it does not really make sense in terms of business logic.

, In Kotlin
List
is by default immutable and mutable version of Lists is called MutableList
.
Hence if you have something like :
val list: List<String> = ArrayList()
In this case you will not get an add()
method as list is immutable. Hence you will have to declare a MutableList
as shown below :
val list: MutableList<String> = ArrayList()
Now you will see an add()
method and you can add elements to any list.

You can reload parent window location using :
window.opener.location.href = window.opener.location.href;
The '-Wait' option seemed to block for me even though my process had finished.
I tried Adrian's solution and it works. But I used Wait-Process instead of relying on a side effect of retrieving the process handle.
So:
$proc = Start-Process $msbuild -PassThru
Wait-Process -InputObject $proc
if ($proc.ExitCode -ne 0) {
Write-Warning "$_ exited with status code $($proc.ExitCode)"
}
I use buffers like tabs, using the BufExplorer plugin and a few macros:
" CTRL+b opens the buffer list
map <C-b> <esc>:BufExplorer<cr>
" gz in command mode closes the current buffer
map gz :bdelete<cr>
" g[bB] in command mode switch to the next/prev. buffer
map gb :bnext<cr>
map gB :bprev<cr>
With BufExplorer you don't have a tab bar at the top, but on the other hand it saves space on your screen, plus you can have an infinite number of files/buffers open and the buffer list is searchable...
I disagree with the accepted answer being "the easiest", particularly if you want to use virtualenv.
You can use the Unofficial Windows Binaries instead. Download the appropriate wheel from there, and install it with pip
:
pip install pywin32-219-cp27-none-win32.whl
(Make sure you pick the one for the right version and bitness of Python).
You might be able to get the URL and install it via pip
without downloading it first, but they're made it a bit harder to just grab the URL. Probably better to download it and host it somewhere yourself.
If you only need to modify the page num you can replace it:
var newUrl = location.href.replace("page="+currentPageNum, "page="+newPageNum);
There is another solution for this.
Consider the quotes as part of the fields delimiter, by editing the fmt file.
You can check this out for more information:
An extract of the link above:
The only way to remove the quotation marks would be to modify the column delimiters specified during the import operation. The only drawback here is that if you inspect the data to be inserted, you will very quickly realize that the column delimiters are different for each column (Delimiters highlighted above).
So to specify different column delimiters for each column, you would need to use a format file if you plan to use Bulk Insert or BCP. If you generate a format file for the above table structure, it would be as follows:
9.0
3
1 SQLCHAR 0 5 "\t" 1 FName SQL_Latin1_General_CP1_CI_AS
2 SQLCHAR 0 5 "\t" 2 LName SQL_Latin1_General_CP1_CI_AS
3 SQLCHAR 0 50 "\r\n" 3 Company SQL_Latin1_General_CP1_CI_AS
Modify the format file to represent the correct column delimiters for each column. The new format file to be used will look like this:
9.0
4
1 SQLCHAR 0 0 "\"" 0 FIRST_QUOTE SQL_Latin1_General_CP1_CI_AS
2 SQLCHAR 0 5 "\",\"" 1 FNAME SQL_Latin1_General_CP1_CI_AS
3 SQLCHAR 0 5 "\",\"" 2 LNAME SQL_Latin1_General_CP1_CI_AS
4 SQLCHAR 0 50 "\"\r\n" 3 COMPANY SQL_Latin1_General_CP1_CI_AS
Kotlin and Numeric keyboard
If you are using the numeric keyboard you have to dismiss the keyboard, it will be like:
editText.setOnEditorActionListener { v, actionId, event ->
if (action == EditorInfo.IME_ACTION_DONE || action == EditorInfo.IME_ACTION_NEXT || action == EditorInfo.IME_ACTION_UNSPECIFIED) {
//hide the keyboard
val imm = context.getSystemService(Context.INPUT_METHOD_SERVICE) as InputMethodManager
imm.hideSoftInputFromWindow(windowToken, 0)
//Take action
editValue.clearFocus()
return true
} else {
return false
}
}
If you're going to be doing any sort of arithmetic operations in the DB (multiplying out billing rates and so on), you'll probably want a lot more precision than people here are suggesting, for the same reasons that you'd never want to use anything less than a double-precision floating point value in application code.
I ran into the 'Expecting: ANY PRIVATE KEY' error when using openssl on Windows (Ubuntu Bash and Git Bash had the same issue).
The cause of the problem was that I'd saved the key and certificate files in Notepad using UTF8. Resaving both files in ANSI format solved the problem.
var isMobileDevice = navigator.userAgent.match(/iPad|iPhone|iPod/i) != null

Take the following folder structure
notice:
Now in the index.html.en

<span>I'm purple because I'm referenced from this current directory</span>
</p>
<p>
<span>src="/check_mark.png"</span>
<img src="/check_mark.png" />
<span>I'm green because I'm referenced from the ROOT directory</span>
</p>
<p>
<span>src="subfolder/check_mark.png"</span>
<img src="subfolder/check_mark.png" />
<span>I'm yellow because I'm referenced from the child of this current directory</span>
</p>
<p>
<span>src="/subfolder/check_mark.png"</span>
<img src="/subfolder/check_mark.png" />
<span>I'm orange because I'm referenced from the child of the ROOT directory</span>
</p>
<p>
<span>src="../subfolder/check_mark.png"</span>
<img src="../subfolder/check_mark.png" />
<span>I'm purple because I'm referenced from the parent of this current directory</span>
</p>
<p>
<span>src="subfolder/subfolder/check_mark.png"</span>
<img src="subfolder/subfolder/check_mark.png" />
<span>I'm [broken] because there is no subfolder two children down from this current directory</span>

<img src="/subfolder/subfolder/check_mark.png" />

Now if you load up the index.html.en

VBA functions treat the function name itself as a sort of variable. So instead of using a "return
" statement, you would just say:
test = 1
Notice, though, that this does not break out of the function. Any code after this statement will also be executed. Thus, you can have many assignment statements that assign different values to test
, and whatever the value is when you reach the end of the function will be the value returned.
Taking the answer above as guidance;
I made an extra graph for "hours worked by month", then copy/special-pasted it as a 'linked picture' for use under my other graphs. in other words, I copy pasted my existing graphs over the linked picture made from my new graph with the new axis.. And because it is a linked picture it always updates.
Make it easy on yourself though, make sure you copy an existing graph to build your 'picture' graph - then delete the series or change the data source to what you need as an extra axis. That way you won't have to mess around resizing.
The results were not too bad considering what I wanted to achieve; basically a list of incident frequency bar graph, with a performance tread line, and then a solid 'backdrop' of hours worked.
Thanks to the guy above for the idea!
As of right now ES6 import, export is always compiled to CommonJS, so there is no benefit using one or other. Although usage of ES6 is recommended since it should be advantageous when native support from browsers released. The reason being, you can import partials from one file while with CommonJS you have to require all of the file.
ES6 → import, export default, export
CommonJS → require, module.exports, exports.foo
Below is common usage of those.
ES6 export default
// hello.js
function hello() {
return 'hello'
}
export default hello
// app.js
import hello from './hello'
hello() // returns hello
ES6 export multiple and import multiple
// hello.js
function hello1() {
return 'hello1'
}
function hello2() {
return 'hello2'
}
export { hello1, hello2 }
// app.js
import { hello1, hello2 } from './hello'
hello1() // returns hello1
hello2() // returns hello2
CommonJS module.exports
// hello.js
function hello() {
return 'hello'
}
module.exports = hello
// app.js
const hello = require('./hello')
hello() // returns hello
CommonJS module.exports multiple
// hello.js
function hello1() {
return 'hello1'
}
function hello2() {
return 'hello2'
}
module.exports = {
hello1,
hello2
}
// app.js
const hello = require('./hello')
hello.hello1() // returns hello1
hello.hello2() // returns hello2
In addition to Tom Blodget's response, you may simply add @HtmlBeginForm as the form action, like this:
<form id="form" method="post" action="@Html.BeginForm("action", "controller", FormMethod.Post, new { onsubmit = "this.querySelectorAll('input').forEach(i => i.disabled = false)" })"
using the Integer data type with values 0 and 1 is the fastest.
I think there is no out-of-the-box support for that in VS Code.
You can install a plugin to give you similar functionality. Eg.:
https://marketplace.visualstudio.com/items?itemName=micnil.vscode-checkpoints
Or the more famous:
https://marketplace.visualstudio.com/items?itemName=xyz.local-history
Some details may need to be configured: The VS Code search gets confused sometimes because of additional folders created by this type of plugins. You can configure it to ignore such folders or change their locations (adding such folders to your .gitignore
file also solves this problem).
You can try using the following code:
$filename = 'myfile';
$path = 'your path goes here';
$file = $path . "/" . $filename;
$mailto = '[email protected]';
$subject = 'Subject';
$message = 'My message';
$content = file_get_contents($file);
$content = chunk_split(base64_encode($content));
// a random hash will be necessary to send mixed content
$separator = md5(time());
// carriage return type (RFC)
$eol = "\r\n";
// main header (multipart mandatory)
$headers = "From: name <[email protected]>" . $eol;
$headers .= "MIME-Version: 1.0" . $eol;
$headers .= "Content-Type: multipart/mixed; boundary=\"" . $separator . "\"" . $eol;
$headers .= "Content-Transfer-Encoding: 7bit" . $eol;
$headers .= "This is a MIME encoded message." . $eol;
// message
$body = "--" . $separator . $eol;
$body .= "Content-Type: text/plain; charset=\"iso-8859-1\"" . $eol;
$body .= "Content-Transfer-Encoding: 8bit" . $eol;
$body .= $message . $eol;
// attachment
$body .= "--" . $separator . $eol;
$body .= "Content-Type: application/octet-stream; name=\"" . $filename . "\"" . $eol;
$body .= "Content-Transfer-Encoding: base64" . $eol;
$body .= "Content-Disposition: attachment" . $eol;
$body .= $content . $eol;
$body .= "--" . $separator . "--";
//SEND Mail
if (mail($mailto, $subject, $body, $headers)) {
echo "mail send ... OK"; // or use booleans here
} else {
echo "mail send ... ERROR!";
print_r( error_get_last() );
}
Edit 14-June-2018
for more readability in some of email provider use
$body .= $eol . $message . $eol . $eol;
and
$body .= $eol . $content . $eol . $eol;
In order to map a the result set of query to a particular Java class you'll probably be best (assuming you're interested in using the object elsewhere) off with a RowMapper to convert the columns in the result set into an object instance.
See Section 12.2.1.1 of Data access with JDBC on how to use a row mapper.
In short, you'll need something like:
List<Conversation> actors = jdbcTemplate.query(
SELECT_ALL_CONVERSATIONS_SQL_FULL,
new Object[] {userId, dateFrom, dateTo},
new RowMapper<Conversation>() {
public Conversation mapRow(ResultSet rs, int rowNum) throws SQLException {
Conversation c = new Conversation();
c.setId(rs.getLong(1));
c.setRoom(rs.getString(2));
[...]
return c;
}
});
Please note that Integer.parseInt throws an NumberFormatException if the passed string doesn't contain a parsable string.
Another way would be to encode the quotes using htmlspecialchars:
$json_array = array(
'title' => 'Example string\'s with "special" characters'
);
$json_decode = htmlspecialchars(json_encode($json_array), ENT_QUOTES, 'UTF-8');
Plots created using seaborn need to be displayed like ordinary matplotlib plots. This can be done using the
plt.show()
function from matplotlib.
Originally I posted the solution to use the already imported matplotlib object from seaborn (sns.plt.show()
) however this is considered to be a bad practice. Therefore, simply directly import the matplotlib.pyplot module and show your plots with
import matplotlib.pyplot as plt
plt.show()
If the IPython notebook is used the inline backend can be invoked to remove the necessity of calling show after each plot. The respective magic is
%matplotlib inline
Below code helped my object to be refreshed with fresh database values. The Entry(object).Reload() command forces the object to recall database values
GM_MEMBERS member = DatabaseObjectContext.GM_MEMBERS.FirstOrDefault(p => p.Username == username && p.ApplicationName == this.ApplicationName);
DatabaseObjectContext.Entry(member).Reload();
Just go to the SQL Server Management Studio -> Tools -> Options -> Designer; and Uncheck the option "prevent saving changes that require table re-creation".
Looks like you have an extra parenthesis.
The following portion is parsed as an assignment so the interpreter/compiler will look for a semi-colon or attempt to insert one if certain conditions are met.
foob_name = $this.attr('name').replace(/\[(\d+)\]/, function($0, $1) {
return '[' + (+$1 + 1) + ']';
})
jqXHR.done(function( data, textStatus, jqXHR ) {});
An alternative construct to the success callback option, the .done() method replaces the deprecated jqXHR.success() method. Refer to deferred.done() for implementation details.
The point it is just an alternative for success callback option, and jqXHR.success()
is deprecated.
You can combine the check and cast into one statement:
let touch = object.anyObject() as UITouch
if let picker = touch.view as? UIPickerView {
...
}
Then you can use picker
within the if
block.

For older browsers, use the for-in

You are running into the old problem with floating point numbers that not all numbers can be represented exactly. The command line is just showing you the full floating point form from memory.
With floating point representation, your rounded version is the same number. Since computers are binary, they store floating point numbers as an integer and then divide it by a power of two so 13.95 will be represented in a similar fashion to 125650429603636838/(2**53).
Double precision numbers have 53 bits (16 digits) of precision and regular floats have 24 bits (8 digits) of precision. The floating point type in Python uses double precision to store the values.
For example,
>>> 125650429603636838/(2**53)
13.949999999999999
>>> 234042163/(2**24)
13.949999988079071
>>> a = 13.946
>>> print(a)
13.946
>>> print("%.2f" % a)
13.95
>>> round(a,2)
13.949999999999999
>>> print("%.2f" % round(a, 2))
13.95
>>> print("{:.2f}".format(a))
13.95
>>> print("{:.2f}".format(round(a, 2)))
13.95
>>> print("{:.15f}".format(round(a, 2)))

Here is an implementation using queue:

throws FileNotFoundException, IOException {
List<String> filePathList = new ArrayList<String>();
Queue<Path> fileQueue = new LinkedList<Path>();
fileQueue.add(hdfsFilePath);

Path filePath = fileQueue.remove();
if (fs.isFile(filePath)) {
filePathList.add(filePath.toString());

Exclusive Or is defined as follows
def xor( a, b ):
return (a or b) and not (a and b)
Try this:
select col1, col2, 'ABC' as col3 from Table1 where col1 = 0;
I think this might be the simplest solution:
<tr onclick="location.href='http://www.mywebsite.com'" style="cursor: pointer">
<td>...</td>
<td>...</td>
</tr>
The cursor CSS property sets the type of cursor, if any, to show when the mouse pointer is over an element.
The inline css defines that for that element the cursor will be formatted as a pointer, so you don't need the 'hover'.
Committing package-lock.json to the source code version control means that the project will use a specific version of dependencies that may or may not match those defined in package.json. while the dependency has a specific version without any Caret (^) and Tilde (~) as you can see, that's mean the dependency will not be updated to the most recent version. and npm install will pick up the same version as well as we need it for our current version of Angular.
Note : package-lock.json highly recommended to commit it IF I added any Caret (^) and Tilde (~) to the dependency to be updated during the CI.

I just figured. You need to add a shared folder using VirtualBox before you access it with the guest.
Click "Device" in the menu bar--->Shared File--->add a directory and name it
then in the guest terminal, use:
sudo mount -t vboxsf myFileName ~/destination
Dont directly refer to the host directory
If you want to avoid the fopen/fputcsv sub-systems here's a snippet that builds an escaped CSV string from an associative array....
$output = '';
foreach ($list as $row) {
$output .= '"' . implode('", "', array_values($row)) . '"' . "\r\n";
}
Or from a list of objects...
foreach ($list as $obj) {
$output .= '"' . implode('", "', array_values((array) $obj)) . '"' . "\r\n";
}
Then you can output the string as desired.
Try to just use isNotNull function.
df.filter(df.dt_mvmt.isNotNull()).count()
The easiest way I found included the following steps (the only requirement is it to be in Win7+):
It sounds long, but in reality is very fast.. (it sounds long as I described even the smallest steps)
You have to configure SMTP on your server. You can use G Suite SMTP by Google for free:
<?php
$mail = new PHPMailer(true);
// Send mail using Gmail
if($send_using_gmail){
$mail->IsSMTP(); // telling the class to use SMTP
$mail->SMTPAuth = true; // enable SMTP authentication
$mail->SMTPSecure = "ssl"; // sets the prefix to the servier
$mail->Host = "smtp.gmail.com"; // sets GMAIL as the SMTP server
$mail->Port = 465; // set the SMTP port for the GMAIL server
$mail->Username = "[email protected]"; // GMAIL username
$mail->Password = "your-gmail-password"; // GMAIL password
}
// Typical mail data
$mail->AddAddress($email, $name);
$mail->SetFrom($email_from, $name_from);
$mail->Subject = "My Subject";
$mail->Body = "Mail contents";
try{
$mail->Send();
echo "Success!";
} catch(Exception $e){
// Something went bad
echo "Fail :(";
}
?>
Read more about PHPMailer
here.
Basically like this,
<?php
$link = ""; // Link goes here!
print "<a href="'.$link.'">Link</a>";
?>
You need to change the sshd_config
file in the remote server (probably in /etc/ssh/sshd_config
).
Change
PasswordAuthentication no
to
PasswordAuthentication yes
And then restart the sshd
daemon.
For AF_UNIX you can use call unlink (path); after close() socket in "server" app
As input and output streams are just start and end point, the solution is to temporary store data in byte array. So you must create intermediate ByteArrayOutputStream
, from which you create byte[]
that is used as input for new ByteArrayInputStream
.
public void doTwoThingsWithStream(InputStream inStream, OutputStream outStream){
//create temporary bayte array output stream
ByteArrayOutputStream baos = new ByteArrayOutputStream();
doFirstThing(inStream, baos);
//create input stream from baos
InputStream isFromFirstData = new ByteArrayInputStream(baos.toByteArray());
doSecondThing(isFromFirstData, outStream);
}
Hope it helps.
If for debugging all you want is a string (sort of implied by the OP but not explicitly stated), simply use toString
on the extras Bundle
:
intent.getExtras().toString()
It returns a string such as:
Bundle[{key1=value1, key2=value2, key3=value3}]
Documentation: Bundle.toString() (it's unfortunately the default Object.toString()
javadoc and as such quite useless here.)
Quick work around
Simply enclose the list within a new list, as done for col2 in the data frame below. The reason it works is that python takes the outer list (of lists) and converts it into a column as if it were containing normal scalar items, which is lists in our case and not normal scalars.
mydict={'col1':[1,2,3],'col2':[[1, 4], [2, 5], [3, 6]]}
data=pd.DataFrame(mydict)
data
col1 col2
0 1 [1, 4]
1 2 [2, 5]
2 3 [3, 6]
I know the purists will hate this method, but you can cat
the file.
NAMES=`cat scripts/names.txt` #names from names.txt file
for NAME in $NAMES; do
echo "$NAME"
done
Thx guys, I finally found the solution, a really basic one.. In my controller I have
$scope.mySplit = function(string, nb) {
var array = string.split(',');
return array[nb];
}
and in my view
{{mySplit(string,0)}}

MY SOLUTION!!!!!!! I fixed this problem when I was trying to install business objects. When the installer failed to register .dll's I inputted the MSVCR71.dll into both system32 and sysWOW64 then clicked retry. Installation finished. I did try adding this in before and after install but, install still failed.

I created a function for updating GridView column headers for a list and call it whenever the window is re-sized or the listview updates it's layout.
public void correctColumnWidths()
{
double remainingSpace = myList.ActualWidth;
if (remainingSpace > 0)
{
for (int i = 0; i < (myList.View as GridView).Columns.Count; i++)
if (i != 2)
remainingSpace -= (myList.View as GridView).Columns[i].ActualWidth;
//Leave 15 px free for scrollbar
remainingSpace -= 15;
(myList.View as GridView).Columns[2].Width = remainingSpace;
}
}
You can learn some tutorials for JSP page direct access database (mysql) here
Notes:
import sql tag library in jsp page
<%@ taglib uri="http://java.sun.com/jsp/jstl/sql" prefix="sql"%>
then set datasource on page
<sql:setDataSource var="ds" driver="com.mysql.jdbc.Driver" url="jdbc:mysql://<yourhost>/<yourdb>" user="<user>" password="<password>"/>
Now query what you want on page
<sql:query dataSource="${ds}" var="result"> //ref defined 'ds'
SELECT * from <your-table>;
</sql:query>
Finally you can populate dropdowns on page using c:forEach
tag to iterate result rows in select

None of these answers solved my problem, which was that the items weren't the same width in my makeshift flexbox table when it was shrunk to a width too small.
The solution for me was simply to put overflow: hidden;

rm -f .git/index.lock
didn't help, because I had a locked file that couldn't be deleted. So, index.lock
also had been captured by some application.
In Windows I downloaded an alternative to Unlocker
called Lock Hunter
and deleted both files. Git
captured them.
In Swing its fairly common to write a class that implements ActionListener
and add the current instance (ie 'this') as an ActionListener for components.
public class MyDialog extends JDialog implements ActionListener
{
public MyDialog()
{
JButton myButton = new JButton("Hello");
myButton.addActionListener(this);
}
public void actionPerformed(ActionEvent evt)
{
System.out.println("Hurdy Gurdy!");
}
}
span:not(:last-child) {
margin-right: 10px;
}
Well its a sequential process. The Request first treat by FrontController and then moves towards our own customize controller with @Controller annotation.
but our controller method is binding bean using modelattribute and we are also performing few validations on bean values.
so instead of moving the request to our controller class, FrontController moves it towards one interceptor which creates the temp object of our bean and the validate the values. if validation successful then bind the temp obj values with our actual bean which is stored in @ModelAttribute otherwise if validation fails it does not bind and moves the resp towards error page or wherever u want.

HTML event handler code behaves like the body of a JavaScript function. Many languages such as C or Perl implicitly return the value of the last expression evaluated in the function body. JavaScript doesn't, it discards it and returns undefined unless you write an explicit return

Simplifying from pctroll's answer, similarly based on this blog post.
# look up the commit id in git log or on github, e.g. 42480f3, then do
git checkout master
git checkout your_branch
git revert 42480f3
# a text editor will open, close it with ctrl+x (editor dependent)
git push origin your_branch
# or replace origin with your remote
Alternately, you could do a Text to Columns with space as the delimiter.
I think you can do something like this, the syntax might be wrong, havent used C# in a while To get the last item
Dictionary<string, int>.KeyCollection keys = mydict.keys;
string lastKey = keys.Last();
or use Max instead of Last to get the max value, I dont know which one fits your code better.
I just went through this, and all of your answers helped me toward a good solution, for me. I resisted going the route suggested by, just because I found it hard to read and comprehend.
Here's what I did. I had a BOOL being carried around in a variable called "_talkative".
When I set my default (NSUserDefaults) object, I set it as an object, as I could then test to see if it was nil:
//converting BOOL to an object so we can check on nil
[defaults setObject:@(_talkative) forKey:@"talkative"];
Then when I went to see if it existed, I used:
if ([defaults objectForKey:@"talkative"]!=nil )
{
Then I used the object as a BOOL:
if ([defaults boolForKey:@"talkative"]) {
...
This seems to work in my case. It just made more visual sense to me.
Modification of @Ilya_Gazman answer
private void callJavaScript(WebView view, String methodName, Object...params){
StringBuilder stringBuilder = new StringBuilder();
stringBuilder.append("javascript:try{");
stringBuilder.append(methodName);
stringBuilder.append("(");
String separator = "";
for (Object param : params) {
stringBuilder.append(separator);
separator = ",";
if(param instanceof String){
stringBuilder.append("'");
}
stringBuilder.append(param.toString().replace("'", "\\'"));
if(param instanceof String){
stringBuilder.append("'");
}
}
stringBuilder.append(")}catch(error){console.error(error.message);}");
final String call = stringBuilder.toString();
Log.i(TAG, "callJavaScript: call="+call);
view.loadUrl(call);
}
will correctly create JS calls e.g.
callJavaScript(mBrowser, "alert", "abc", "def");
//javascript:try{alert('abc','def')}catch(error){console.error(error.message);}
callJavaScript(mBrowser, "alert", 1, true, "abc");
//javascript:try{alert(1,true,'abc')}catch(error){console.error(error.message);}
Note that objects will not be passed correctly - but you can serialize them before passing as an argument.
Also I've changed where the error goes, I've diverted it to the console log which can be listened by:
webView.setWebChromeClient(new CustomWebChromeClient());
and client
class CustomWebChromeClient extends WebChromeClient {
private static final String TAG = "CustomWebChromeClient";
@Override
public boolean onConsoleMessage(ConsoleMessage cm) {
Log.d(TAG, String.format("%s @ %d: %s", cm.message(),
cm.lineNumber(), cm.sourceId()));
return true;
}
}
You can reuse your confirm:
function doConfirm(body, $_nombrefuncion)
{ var param = undefined;
var $confirm = $("<div id='confirm' class='hide'></div>").dialog({
autoOpen: false,
buttons: {
Yes: function() {
param = true;
$_nombrefuncion(param);
$(this).dialog('close');
},
No: function() {
param = false;
$_nombrefuncion(param);
$(this).dialog('close');
}
}
});
$confirm.html("<h3>"+body+"<h3>");
$confirm.dialog('open');
};
// for this form just u must change or create a new function for to reuse the confirm
function resultadoconfirmresetVTyBFD(param){
$fecha = $("#asigfecha").val();
if(param ==true){
// DO THE CONFIRM
}
}
//Now just u must call the function doConfirm
doConfirm('body message',resultadoconfirmresetVTyBFD);
"Plain Old C# Object"
Just a normal class, no attributes describing infrastructure concerns or other responsibilities that your domain objects shouldn't have.
EDIT - as other answers have stated, it is technically "Plain Old CLR Object" but I, like David Arno comments, prefer "Plain Old Class Object" to avoid ties to specific languages or technologies.
TO CLARIFY: In other words, they don’t derive from some special base class, nor do they return any special types for their properties.
See below for an example of each.
Example of a POCO:
public class Person
{
public string Name { get; set; }
public int Age { get; set; }
}
Example of something that isn’t a POCO:
public class PersonComponent : System.ComponentModel.Component
{
[DesignerSerializationVisibility(DesignerSerializationVisibility.Hidden)]
public string Name { get; set; }
public int Age { get; set; }
}
The example above both inherits from a special class to give it additional behavior as well as uses a custom attribute to change behavior… the same properties exist on both classes, but one is not just a plain old object anymore.
Status 422 (RFC 4918, Section 11.2) comes to mind:
The 422 (Unprocessable Entity) status code means the server understands the content type of the request entity (hence a 415(Unsupported Media Type) status code is inappropriate), and the syntax of the request entity is correct (thus a 400 (Bad Request) status code is inappropriate) but was unable to process the contained instructions. For example, this error condition may occur if an XML request body contains well-formed (i.e., syntactically correct), but semantically erroneous, XML instructions.
List<T>.ForEach
doesn't play particularly well with async
(neither does LINQ-to-objects, for the same reasons).
In this case, I recommend projecting each element into an asynchronous operation, and you can then (asynchronously) wait for them all to complete.
using (DataContext db = new DataLayer.DataContext())
{
var tasks = db.Groups.ToList().Select(i => GetAdminsFromGroupAsync(i.Gid));
var results = await Task.WhenAll(tasks);
}
The benefits of this approach over giving an async
delegate to ForEach
are:
async void
cannot be caught with catch
; this approach will propagate exceptions at the await Task.WhenAll
line, allowing natural exception handling.await Task.WhenAll
. If you use async void
, you cannot easily tell when the operations have completed.GetAdminsFromGroupAsync
sounds like it's an operation that produces a result (the admins), and such code is more natural if such operations can return their results rather than setting a value as a side effect.First think you should create object $res = new \stdClass();
then assign object with key and value thay $res->success = false;
You can add an onclick function to your submit button, but you won't be able to submit your function by pressing enter. For my part, I use this:
<form action="" method="post" onsubmit="your_ajax_function(); return false;">
Your Name <br/>
<input type="text" name="name" id="name" />
<br/>
<input type="submit" id="submit" value="Submit" />
</form>
Hope it helps.
Other solutions are great but they didn't take care of the fact that watermark shouldn't get selected on selection from the mouse. This fiddle takes care or that: https://jsfiddle.net/MiKr13/d1r4o0jg/9/
This will be better option for pdf or static html.

-webkit-user-select: none;
-khtml-user-select: none;
-moz-user-select: none;
-ms-user-select: none;
right: 5px;
bottom: 5px;
}
try this
if(isset($itemCost) != '' && isset($itemQty) != '')
{
$diffPricePercent = (($actual * 100) / $itemCost) / $itemQty;
}
else
{
echo "either of itemCost or itemQty are null";
}
A StaticResource will be resolved and assigned to the property during the loading of the XAML which occurs before the application is actually run. It will only be assigned once and any changes to resource dictionary ignored.
A DynamicResource assigns an Expression object to the property during loading but does not actually lookup the resource until runtime when the Expression object is asked for the value. This defers looking up the resource until it is needed at runtime. A good example would be a forward reference to a resource defined later on in the XAML. Another example is a resource that will not even exist until runtime. It will update the target if the source resource dictionary is changed.
This worked for me: I needed to generate just three random alphanumeric characters for an ID, but it could work for any length up to 15 or so.
declare @DesiredLength as int = 3;
select substring(replace(newID(),'-',''),cast(RAND()*(31-@DesiredLength) as int),@DesiredLength);

After reviewing the other answers and considering CodeInChaos' comments, along with CodeInChaos still biased (although less) answer, I thought a final ultimate cut and paste solution was needed. So while updating my answer I decided to go all out.
For an up to date version of this code, please visit the new Hg repository on Bitbucket: https://bitbucket.org/merarischroeder/secureswiftrandom. I recommend you copy and paste the code from: https://bitbucket.org/merarischroeder/secureswiftrandom/src/6c14b874f34a3f6576b0213379ecdf0ffc7496ea/Code/Alivate.SolidSwiftRandom/SolidSwiftRandom.cs?at=default&fileviewer=file-view-default (make sure you click the Raw button to make it easier to copy and make sure you have the latest version, I think this link goes to a specific version of the code, not the latest).

For history - my older solution for this answer, used Random object:
private static char[] charSet =
"abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789".ToCharArray();
static rGen = new Random(); //Must share, because the clock seed only has Ticks (~10ms) resolution, yet lock has only 20-50ns delay.
static int byteSize = 256; //Labelling convenience
static int biasZone = byteSize - (byteSize % charSet.Length);
static bool SlightlyMoreSecurityNeeded = true; //Configuration - needs to be true, if more security is desired and if charSet.Length is not divisible by 2^X.
public string GenerateRandomString(int Length) //Configurable output string length
{
byte[] rBytes = new byte[Length]; //Do as much before and after lock as possible
char[] rName = new char[Length];
lock (rGen) //~20-50ns
{
rGen.NextBytes(rBytes);
for (int i = 0; i < Length; i++)
{
while (SlightlyMoreSecurityNeeded && rBytes[i] >= biasZone) //Secure against 1/5 increased bias of index[0-7] values against others. Note: Must exclude where it == biasZone (that is >=), otherwise there's still a bias on index 0.
rBytes[i] = rGen.NextByte();
rName[i] = charSet[rBytes[i] % charSet.Length];
}
}
return new string(rName);
}

scp will do the job, but there is one wrinkle: the connection to the second remote destination will use the configuration on the first remote destination, so if you use .ssh/config on the local environment, and you expect rsa and dsa keys to work, you have to forward your agent to the first remote host.
In swift 3 use:

You can add color in the style rule of your input: color:#ccc;
I don't like function_exists('fun_name')
because it relies on the function name being turned into a string, plus, you have to name it twice. Could easily break with refactoring.
Declare your function as a lambda expression (I haven't seen this solution mentioned):
$generate_salt = function()
{
...
};
And use thusly:
$salt = $generate_salt();
Then, at re-execution of said PHP code, the function simply overwrites the previous declaration.
I tried all of the listed answers and none of them was useful. The problem was due to existence of an another plist file linked from a submodule via cocoapods. Luckily this was my own module, so I just deleted this plist from the submodule project and reinstalled pods.
Later on I understood that the key of the problem was in the name of that second plist: simply info.plist
. You may rename the file and relink it via a sources
section of a submodule
That second plist file had a unique name, so Xcode was not supposed to become frustrated. Even my target settings pointed on a main plist, not on a info.plist
. Looks like Xcode takes special consideraions about that name
The bug reproduced in Xcode 6.4 and Xcode 7.0
Do C-b
, :show
which will show you all your current settings. /green
, nnn
will find you which properties have been set to green, the default. Do C-b
, :set window-status-bg cyan
and the bottom bar should change colour.
List available colours for tmux
You can tell more easily by the titles and the colours as they're actually set in your live session :show
, than by searching through the man
page, in my opinion. It is a very well-written man
page when you have the time though.
If you don't like one of your changes and you can't remember how it was originally set, you can open do a new tmux session. To change settings for good edit ~/.tmux.conf
with a line like set window-status-bg -g cyan
. Here's mine: https://gist.github.com/9083598
Using jquery
var favicon = $("link[rel='shortcut icon']").attr("href") ||
$("link[rel='icon']").attr("href") || "";
You can also look into using the Collection Object. This usually works better than an array for custom objects, since it dynamically sizes and has methods for:
Plus its normally easier to loop through a collection too since you can use the for...each structure very easily with a collection.
You can remove the whitespaces via css using white-space so you can keep your pretty HTML layout. Don't forget to set the white-space back to normal again if you want your text to wrap inside the columns.
Tested in IE9, Chrome 18, FF 12
.container { white-space: nowrap; }
.column { display: inline-block; width: 50%; white-space: normal; }
<div class="container">
<div class="column">text that can wrap</div>
<div class="column">text that can wrap</div>
</div>
This code works for me:
Configuration config = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);
config.AppSettings.Settings["test"].Value = "blah";
config.Save(ConfigurationSaveMode.Modified);
ConfigurationManager.RefreshSection("appSettings");
Note: it doesn't update the solution item 'app.config', but the '.exe.config' one in the bin/ folder if you run it with F5.
List<String> myStringList = new List<string>(); foreach (string s in myStringArray) { if (!myStringList.Contains(s)) { myStringList.Add(s); } }
This is O(n^2), which won't matter for a short list which is going to be stuffed into a combo, but could be rapidly be a problem on a big collection.
To continue with your older gradle version, we can use below solution:
Notice the file android-ndk-r17-beta2/toolchains/mips64el-linux-android- 4.9/prebuilt/darwin-x86_64/NOTICE-MIPS64. The content of the file is below.
This mips64el-linux-android-4.9 directory exists to make the NDK compatible with the Android SDK's Gradle plugin, version 3.0.1 and earlier, which expects the NDK to have a MIPS64 toolchain directory.
So, i can say, using Android SDK's Gradle plugin above 3.0.1, or create even a directory marked with 'mipsel' and 'mips64el', can both resolve the problem. The latter method is below.
cd "path-to-ndk"
OS_=$(uname -s | tr [A-Z] [a-z])
mkdir -p toolchains/mipsel-linux-android-4.9/prebuilt/${OS_}-x86_64
touch toolchains/mipsel-linux-android-4.9/prebuilt/${OS_}-x86_64/NOTICE-MIPS
mkdir -p toolchains/mips64el-linux-android-4.9/prebuilt/${OS_}-x86_64
touch toolchains/mips64el-linux-android-4.9/prebuilt/${OS_}-x86_64/NOTICE-MIPS64

Use blur event to call your function when element loses focus :
$('#filter').blur(function() {
$('#options').hide();
});
Range("A1").value = Environ("Username")
This is better than Application.Username
, which doesn't always supply the Windows username. Thanks to Kyle for pointing this out.
Application Username
is the name of the User set in Excel > Tools > Options Environ("Username")
is the name you registered for Windows; see Control Panel >SystemI have implemented BasicAuthenticationHandler
for basic authentication so you can use it with standart attributes Authorize
and AllowAnonymous
.
public class BasicAuthenticationHandler : AuthenticationHandler<BasicAuthenticationOptions>
{
protected override Task<AuthenticateResult> HandleAuthenticateAsync()
{
var authHeader = (string)this.Request.Headers["Authorization"];
if (!string.IsNullOrEmpty(authHeader) && authHeader.StartsWith("basic", StringComparison.OrdinalIgnoreCase))
{
//Extract credentials
string encodedUsernamePassword = authHeader.Substring("Basic ".Length).Trim();
Encoding encoding = Encoding.GetEncoding("iso-8859-1");
string usernamePassword = encoding.GetString(Convert.FromBase64String(encodedUsernamePassword));
int seperatorIndex = usernamePassword.IndexOf(':', StringComparison.OrdinalIgnoreCase);
var username = usernamePassword.Substring(0, seperatorIndex);
var password = usernamePassword.Substring(seperatorIndex + 1);
//you also can use this.Context.Authentication here
if (username == "test" && password == "test")
{
var user = new GenericPrincipal(new GenericIdentity("User"), null);
var ticket = new AuthenticationTicket(user, new AuthenticationProperties(), Options.AuthenticationScheme);
return Task.FromResult(AuthenticateResult.Success(ticket));
}
else
{
return Task.FromResult(AuthenticateResult.Fail("No valid user."));
}
}
this.Response.Headers["WWW-Authenticate"]= "Basic realm=\"yourawesomesite.net\"";
return Task.FromResult(AuthenticateResult.Fail("No credentials."));
}
}
public class BasicAuthenticationMiddleware : AuthenticationMiddleware<BasicAuthenticationOptions>
{
public BasicAuthenticationMiddleware(
RequestDelegate next,
IOptions<BasicAuthenticationOptions> options,
ILoggerFactory loggerFactory,
UrlEncoder encoder)
: base(next, options, loggerFactory, encoder)
{
}
protected override AuthenticationHandler<BasicAuthenticationOptions> CreateHandler()
{
return new BasicAuthenticationHandler();
}
}
public class BasicAuthenticationOptions : AuthenticationOptions
{
public BasicAuthenticationOptions()
{
AuthenticationScheme = "Basic";
AutomaticAuthenticate = true;
}
}
Registration at Startup.cs - app.UseMiddleware<BasicAuthenticationMiddleware>();
. With this code, you can restrict any controller with standart attribute Autorize:
[Authorize(ActiveAuthenticationSchemes = "Basic")]
[Route("api/[controller]")]
public class ValuesController : Controller
and use attribute AllowAnonymous
if you apply authorize filter on application level.
I liked JonBrave's answer but I have messy enough working directories that commit -a scares me a bit, so here's what I've done:
git config --global alias.exclude-ignored '!git ls-files -z --ignored --exclude-standard | xargs -0 git rm -r --cached && git ls-files -z --ignored --exclude-standard | xargs -0 git stage && git stage .gitignore && git commit -m "new gitignore and remove ignored files from index"'
breaking it down:
git ls-files -z --ignored --exclude-standard | xargs -0 git rm -r --cached
git ls-files -z --ignored --exclude-standard | xargs -0 git stage
git stage .gitignore
git commit -m "new gitignore and remove ignored files from index"
Performance wise StringBuffer is much better than String ; because whenever you apply concatenation on String Object then new String object are created on each concatenation.
Principal Rule : String are immutable(Non Modifiable) and StringBuffer are mutable(Modifiable)
Here is the programmatic experiment where you get the performance difference
public class Test {
public static int LOOP_ITERATION= 100000;
public static void stringTest(){
long startTime = System.currentTimeMillis();
String string = "This";
for(int i=0;i<LOOP_ITERATION;i++){
string = string+"Yasir";
}
long endTime = System.currentTimeMillis();
System.out.println(endTime - startTime);
}
public static void stringBufferTest(){
long startTime = System.currentTimeMillis();
StringBuffer stringBuffer = new StringBuffer("This");
for(int i=0;i<LOOP_ITERATION;i++){
stringBuffer.append("Yasir");
}
long endTime = System.currentTimeMillis();
System.out.println(endTime - startTime);
}
public static void main(String []args){
stringTest()
stringBufferTest();
}
}
Output of String are in my machine 14800
Output of StringBuffer are in my machine 14
You may want to check out the mySQL docs in regard to the date functions. http://dev.mysql.com/doc/refman/5.5/en/date-and-time-functions.html
There is a YEAR() function just as there is a MONTH() function. If you're doing a comparison though is there a reason to chop up the date? Are you truly interested in ignoring day based differences and if so is this how you want to do it?
I've made some changes to the second most popular answer as i found this worked better for me. The changes use window.innerHeight as it is more dynamic than adding your own height for the nav (above used + 570). this allows the code to work on mobile, tablet and desktop dynamicly.
$(window).scroll(() => {
//Distance from top fo document to top of footer
topOfFooter = $('#footer').position().top;
// Distance user has scrolled from top + windows inner height
scrollDistanceFromTopOfDoc = $(document).scrollTop() + window.innerHeight;
// Difference between the two.
scrollDistanceFromTopOfFooter = scrollDistanceFromTopOfDoc - topOfFooter;
// If user has scrolled further than footer,
if (scrollDistanceFromTopOfDoc > topOfFooter) {
// add margin-bottom so button stays above footer.
$('#floating-button').css('margin-bottom', 0 + scrollDistanceFromTopOfFooter);
} else {
// remove margin-bottom so button goes back to the bottom of the page
$('#floating-button').css('margin-bottom', 0);
}
});
You'll first get the dropdown element from the DOM, then loop through the array, and add each element as a new option in the dropdown like this:
// Get dropdown element from DOM
var dropdown = document.getElementById("selectNumber");
// Loop through the array
for (var i = 0; i < myArray.length; ++i) {
// Append the element to the end of Array list
dropdown[dropdown.length] = new Option(myArray[i], myArray[i]);
}?
See JSFiddle for a live demo: http://jsfiddle.net/nExgJ/
This assumes that you're not using JQuery, and you only have the basic DOM API to work with.
One approach you could take is the following method:
// Counts how many of a certain character occurs in the given string
public static int CharCountInString(char chr, string str)
{
return str.Split(chr).Length-1;
}
As per the parameters this method returns the count of a specific character within a specific string.
This method works by splitting the string into an array by the specified character and then returning the length of that array -1.
While a regexp would suit here just fine, I'll present you with an alternative method. It might be a tad faster than the equivalent regexp, but life's all about choices (...or something).
$length = strlen($urlString);
for ($i=0; $i<$length; i++) {
if ($urlString[$i] === '?') {
$urlString[$i+1] = '';
break;
}
}
Weird, I know.
The token has to be placed in an Authorization header according to the following format:
Authorization: Bearer [Token_Value]
import urllib2
import json
def get_auth_token():
"""
get an auth token
"""
req=urllib2.Request("https://xforce-api.mybluemix.net/auth/anonymousToken")
response=urllib2.urlopen(req)
html=response.read()
json_obj=json.loads(html)
token_string=json_obj["token"].encode("ascii","ignore")
return token_string
def get_response_json_object(url, auth_token):
"""
returns json object with info
"""
auth_token=get_auth_token()
req=urllib2.Request(url, None, {"Authorization": "Bearer %s" %auth_token})
response=urllib2.urlopen(req)
html=response.read()
json_obj=json.loads(html)
return json_obj
cp -rv `ls -A | grep -vE "dirToExclude|targetDir"` targetDir
Edit: forgot to exclude the target path as well (otherwise it would recursively copy).
Another way to list only the files is to use:
git diff-tree --no-commit-id --name-only -r HEAD^..HEAD
Or you can use any two commit IDs
