As far as I know you can use all mentioned technologies separately or together. It's up to you. I think you look at the problem from the wrong angle. Material Design is just the way particular elements of the page are designed, behave and put together. Material Design provides great UI/UX, but it relies on the graphic layout (HTML/CSS) rather than JS (events, interactions).
On the other hand, AngularJS and Bootstrap are front-end frameworks that can speed up your development by saving you from writing tons of code. For example, you can build web app utilizing AngularJS, but without Material Design. Or You can build simple HTML5 web page with Material Design without AngularJS or Bootstrap. Finally you can build web app that uses AngularJS with Bootstrap and with Material Design. This is the best scenario. All technologies support each other.
You can check awesome material design components for AngularJS:

Open Command prompt and go to android sdk>platform-tools> adb kill-server
press enter
and again adb start-server

Oh, I just found that command on PostgreSQL forum:
SELECT * FROM pg_stat_activity;
foo = {}
foo[#foo+1]="bar"
foo[#foo+1]="baz"
This works because the #
operator computes the length of the list. The empty list has length 0, etc.
If you're using Lua 5.3+, then you can do almost exactly what you wanted:
foo = {}
setmetatable(foo, { __shl = function (t,v) t[#t+1]=v end })
_= foo << "bar"
_= foo << "baz"
Expressions are not statements in Lua and they need to be used somehow.
ggplot2
and scales
packages can do that:
y <- c(12, 20)/100
x <- c(1, 2)
library(ggplot2)
library(scales)
myplot <- qplot(as.factor(x), y, geom="bar")
myplot + scale_y_continuous(labels=percent)
It seems like the stat()
option has been taken off, causing the error message. Try this:
library(scales)
myplot <- ggplot(mtcars, aes(factor(cyl))) +
geom_bar(aes(y = (..count..)/sum(..count..))) +
scale_y_continuous(labels=percent)
myplot
For me, I update node and npm to the latest version and it works.
It's clumsy, but you can get this from the usage messages for s_client
or s_server
, which are #if
ed at compile time to match the supported protocol versions. Use something like
openssl s_client -help 2>&1 | awk '/-ssl[0-9]|-tls[0-9]/{print $1}'
# in older releases any unknown -option will work; in 1.1.0 must be exactly -help

Requirement:
Find a cell containing the word TOTAL
then to enter a dash in the cell below it.
Solution:
This solution uses the Find
method of the Range
object, as it seems appropriate to use it rather than brute force (For…Next
loop).
For explanation and details about the method see Range.Find method (Excel)
Implementation:
In order to provide flexibility the Find
method is wrapped in this function:
Function Range_ƒFind_Action(sWhat As String, rTrg As Range) As Boolean
Where:
sWhat
: contains the string
to search for
rTrg
: is the range
to be searched
The function returns True
if any match is found, otherwise it returns False
Additionally, every time the function finds a match it passes the resulting range
to the procedure Range_Find_Action
to execute the required action, (i.e. "enter a dash in the cell below it"). The "required action" is in a separated procedure to allow for customization and flexibility.
This is how the function is called:
This test is searching for "total" to show the effect of the MatchCase:=False
. The match can be made case sensitive by changing it to MatchCase:=True
Sub Range_Find_Action_TEST()
Dim sWhat As String, rTrg As Range
Dim sMsgbdy As String
sWhat = "total" 'String to search for (update as required)
Rem Set rTrg = ThisWorkbook.Worksheets("Sht(0)").UsedRange 'Range to Search (use this to search all used cells)
Set rTrg = ThisWorkbook.Worksheets("Sht(0)").Rows(6) 'Range to Search (update as required)
sMsgbdy = IIf(Range_ƒFind_Action(sWhat, rTrg), _
"Cells found were updated successfully", _
"No cells were found.")
MsgBox sMsgbdy, vbInformation, "Range_ƒFind_Action"
End Sub
This is the Find function
Function Range_ƒFind_Action(sWhat As String, rTrg As Range) As Boolean
Dim rCll As Range, s1st As String
With rTrg
Rem Set First Cell Found
Set rCll = .Find(What:=sWhat, After:=.Cells(1), _
LookIn:=xlFormulas, LookAt:=xlPart, _
SearchOrder:=xlByRows, SearchDirection:=xlNext, _
MatchCase:=False, SearchFormat:=False)
Rem Validate First Cell
If rCll Is Nothing Then Exit Function
s1st = rCll.Address
Rem Perform Action
Call Range_Find_Action(rCll)
Do
Rem Find Other Cells
Set rCll = .FindNext(After:=rCll)
Rem Validate Cell vs 1st Cell
If rCll.Address <> s1st Then Call Range_Find_Action(rCll)
Loop Until rCll.Address = s1st
End With
Rem Set Results
Range_ƒFind_Action = True
End Function
This is the Action procedure
Sub Range_Find_Action(rCll)
rCll.Offset(1).Value2 = Chr(167) 'Update as required - Using `§` instead of "-" for visibilty purposes
End Sub

This worked for me by calculating size of string.
It is easy you need to echo the value you need to return and then store it like below
removechars(){
var="some string.rtf"
size=${#var}
echo ${var:0:size-4}
}
removechars
var2=$?
some string

Here is my way of solving this problem (Swift 4):
The idea was to make the simplest possible solution which allows to use placeholders of different colors, resizes to placeholders size, will not overwrite a delegate
meanwhile keeping all UITextView
functions work as expected.
import UIKit
class PlaceholderTextView: UITextView {
var placeholderColor: UIColor = .lightGray
var defaultTextColor: UIColor = .black
private var isShowingPlaceholder = false {
didSet {
if isShowingPlaceholder {
text = placeholder
textColor = placeholderColor
} else {
textColor = defaultTextColor
}
}
}
var placeholder: String? {
didSet {
isShowingPlaceholder = !hasText
}
}
@objc private func textViewDidBeginEditing(notification: Notification) {
textColor = defaultTextColor
if isShowingPlaceholder { text = nil }
}
@objc private func textViewDidEndEditing(notification: Notification) {
isShowingPlaceholder = !hasText
}
// MARK: - Construction -
override init(frame: CGRect, textContainer: NSTextContainer?) {
super.init(frame: frame, textContainer: textContainer)
setup()
}
required init?(coder aDecoder: NSCoder) {
super.init(coder: aDecoder)
setup()
}
private func setup() {
NotificationCenter.default.addObserver(self, selector: #selector(textViewDidBeginEditing(notification:)), name: UITextView.textDidBeginEditingNotification, object: nil)
NotificationCenter.default.addObserver(self, selector: #selector(textViewDidEndEditing(notification:)), name: UITextView.textDidEndEditingNotification, object: nil)
}
// MARK: - Destruction -
deinit { NotificationCenter.default.removeObserver(self) }
}
If you are using Eloquent, in your model put:
public function getPriceAttribute($price)
{
return $this->attributes['price'] = sprintf('U$ %s', number_format($price, 2));
}
Where getPriceAttribute is your field on database. getSomethingAttribute.
It's very easy.

Both do the same work as they are used for routing purposes in SPA(Single Page Application).
URLs to controllers and views (HTML partials). It watches $location.url() and tries to map the path to an existing route definition.
HTML
<div ng-view></div>
Above tag will render the template from the $routeProvider.when()
condition which you had mentioned in .config
(configuration phase) of angular
Limitations:-
ng-view
on page$routeProvider
fails. (to achieve that, we need to use directives like ng-include
, ng-switch
, ng-if
, ng-show
, which looks bad to have them in SPA)AngularUI Router is a routing framework for AngularJS, which allows you to organize the parts of your interface into a state machine. UI-Router is organized around states, which may optionally have routes, as well as other behavior, attached.
Multiple & Named Views
Another great feature is the ability to have multiple ui-views in a template.
While multiple parallel views are a powerful feature, you'll often be able to manage your interfaces more effectively by nesting your view
s, and pairing those views with nested states.
HTML
<div ui-view>
<div ui-view='header'></div>
<div ui-view='content'></div>
<div ui-view='footer'></div>
</div>
The majority of ui-router
's power is it can manage nested state & views.
Pros
ui-view
on single pageui-view="some"
of state just by using absolute routing using @
with state name.@
to change ui-view="some"
. This will replace the ui-view
rather than checking if it is nested or not.ui-sref
to create a href
URL dynamically on the basis of URL
mentioned in a state, also you could give a state params in the json
format.For more Information Angular ui-router
For better flexibility with various nested view with states, I'd prefer you to go for ui-router
This LambdaExceptionUtil
helper class lets you use any checked exceptions in Java streams, like this:
Stream.of("java.lang.Object", "java.lang.Integer", "java.lang.String")
.map(rethrowFunction(Class::forName))
.collect(Collectors.toList());
Note Class::forName
throws ClassNotFoundException
, which is checked. The stream itself also throws ClassNotFoundException
, and NOT some wrapping unchecked exception.

NOTE 1: The rethrow
methods of the LambdaExceptionUtil
class above may be used without fear, and are OK to use in any situation. A big thanks to user @PaoloC who helped solve the last problem: Now the compiler will ask you to add throw clauses and everything's as if you could throw checked exceptions natively on Java 8 streams.
NOTE 2: The uncheck
methods of the LambdaExceptionUtil
class above are bonus methods, and may be safely removed them from the class if you don't want to use them. If you do used them, do it with care, and not before understanding the following use cases, advantages/disadvantages and limitations:
• You may use the uncheck
methods if you are calling a method which literally can never throw the exception that it declares. For example: new String(byteArr, "UTF-8") throws UnsupportedEncodingException, but UTF-8 is guaranteed by the Java spec to always be present. Here, the throws declaration is a nuisance and any solution to silence it with minimal boilerplate is welcome: String text = uncheck(() -> new String(byteArr, "UTF-8"));
• You may use the uncheck
methods if you are implementing a strict interface where you don't have the option for adding a throws declaration, and yet throwing an exception is entirely appropriate. Wrapping an exception just to gain the privilege of throwing it results in a stacktrace with spurious exceptions which contribute no information about what actually went wrong. A good example is Runnable.run(), which does not throw any checked exceptions.
• In any case, if you decide to use the uncheck
methods,
be aware of these 2 consequences of throwing CHECKED exceptions without a throws clause: 1) The calling-code won't be able to catch it by name (if you try, the compiler will say: Exception is never thrown in body of corresponding try statement). It will bubble and probably be caught in the main program loop by some "catch Exception" or "catch Throwable", which may be what you want anyway. 2) It violates the principle of least surprise: it will no longer be enough to catch RuntimeException
to be able to guarantee catching all possible exceptions. For this reason, I believe this should not be done in framework code, but only in business code that you completely control.
If you're just trying to replace one property, lodash _.find
and _.set
should be enough:
var arr = [{id: 1, name: "Person 1"}, {id: 2, name: "Person 2"}];
_.set(_.find(arr, {id: 1}), 'name', 'New Person');
Here's the nearly shortest possible solution to your question. The solution works in python 3.x. For python 2.x change the import
to Tkinter
rather than tkinter
(the difference being the capitalization):
import tkinter as tk
#import Tkinter as tk # for python 2
def create_window():
window = tk.Toplevel(root)
root = tk.Tk()
b = tk.Button(root, text="Create new window", command=create_window)
b.pack()
root.mainloop()
This is definitely not what I recommend as an example of good coding style, but it illustrates the basic concepts: a button with a command, and a function that creates a window.
You can write bash in your package.json:
# package.json

"name": ...,
"version": ...,
"scripts": {
"build": "NODE_ENV=production npm run webpack && cp -v <this> <that> && echo ok",
...
}
}
- Where does
user.id
go afterpassport.serializeUser
has been called?
The user id (you provide as the second argument of the done
function) is saved in the session and is later used to retrieve the whole object via the deserializeUser
function.
serializeUser
determines which data of the user object should be stored in the session. The result of the serializeUser method is attached to the session as req.session.passport.user = {}
. Here for instance, it would be (as we provide the user id as the key) req.session.passport.user = {id: 'xyz'}
- We are calling
passport.deserializeUser
right after it where does it fit in the workflow?
The first argument of deserializeUser
corresponds to the key of the user object that was given to the done
function (see 1.). So your whole object is retrieved with help of that key. That key here is the user id (key can be any key of the user object i.e. name,email etc).
In deserializeUser
that key is matched with the in memory array / database or any data resource.
The fetched object is attached to the request object as req.user

passport.serializeUser(function(user, done) {
done(null, user.id);
}); ¦

A branch is just a reference to a commit. Until you commit anything to the repository, you don't have any branches. You can see this in a non-bare repository as well.
$ mkdir repo
$ cd repo
$ git init

$ git branch
$ touch foo
$ git add foo
$ git commit -m "new file"

You could use the .NET library to do the same thing which i believe is more straightforward.
string ConnectionString = "Provider=Microsoft.ACE.OLEDB.12.0; data source={path of your excel file}; Extended Properties=Excel 12.0;";
OleDbConnection objConn = null;
System.Data.DataTable dt = null;
//Create connection object by using the preceding connection string.
objConn = new OleDbConnection(connString);
objConn.Open();
//Get the data table containg the schema guid.
dt = objConn.GetOleDbSchemaTable(OleDbSchemaGuid.Tables, null);
string sql = string.Format("select * from [{0}$]", sheetName);
var adapter = new System.Data.OleDb.OleDbDataAdapter(sql, ConnectionString);
var ds = new System.Data.DataSet();
string tableName = sheetName;
adapter.Fill(ds, tableName);
System.Data.DataTable data = ds.Tables[tableName];
After you have your data in the datatable you can access them as you would normally do with a DataTable class.
I installed Oracle Express Edition and I have the same error. One of the possible reason that is maybe your user does not have permission to open this shortcut. Here is how I solved the problem.
1. Right-click the shortcut and select the properties
.
2. Now click the Open File Location
.
Now you will see there is a Get_Started
shortcut.
3. Now right-click the Get_Started
and select the properties
. Then select your user and give permission to your user in the security
tab.
If you don't care about this question being specifically about a tableview, and you'd just like to center one view on top of another view here's to do it:
let horizontalConstraint = NSLayoutConstraint(item: newView, attribute: NSLayoutAttribute.CenterX, relatedBy: NSLayoutRelation.Equal, toItem: parentView, attribute: NSLayoutAttribute.CenterX, multiplier: 1, constant: 0)
parentView.addConstraint(horizontalConstraint)
let verticalConstraint = NSLayoutConstraint(item: newView, attribute: NSLayoutAttribute.CenterY, relatedBy: NSLayoutRelation.Equal, toItem: parentView, attribute: NSLayoutAttribute.CenterY, multiplier: 1, constant: 0)
parentView.addConstraint(verticalConstraint)
Check out in your local.properties file
sdk.dir=C\:\\Users\\USERNAME\\AppData\\Local\\Android\\sdk
properly write this format, and also check / slas using for path
There is an option “unlimited scrollback buffer” which you can find under Preferences > Profiles > Terminal
or you can just pump up number of lines that you want to have in history in the same place.
Also, there was just a typo in your original post.
'min:2|max5'
should have been 'min:2|max:5'

I faced same issue few days back, I followed the link mentioned below and I could able to overcome the problem
The easiest way to do this is to format a cell the way you want it, then use the "cell format ..." contextual menu to get to the fill and format colours, use the "more colors ..." button to get to the hexagon colour selector, select the custom tab.
The RGB colours are as in the table at the bottom of the pane. If you prefer HSL values change the color model from RGB to HSL. I have used this to change the saturation on my bad cells. A higher luminosity gives a worse results and the shade of all the cells is the same just the deepness of the colour is modified.

If you have Android Studio then it is very very simple. Just create a MapActivity using Android Studio and after creating it go into google_maps_api.xml. In there there will be a link given in comments. If you paste it in your browser, it will ask a few details to be filled in and after that your API will be generated. There is no need of using keytool and all.
Screen shot:
OSError: [Errno 8] Exec format error
can happen if there is no shebang line at the top of the shell script and you are trying to execute the script directly. Here's an example that reproduces the issue:
>>> with open('a','w') as f: f.write('exit 0') # create the script
...
>>> import os
>>> os.chmod('a', 0b111101101) # rwxr-xr-x make it executable
>>> os.execl('./a', './a') # execute it
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/usr/lib/python2.7/os.py", line 312, in execl
execv(file, args)
OSError: [Errno 8] Exec format error
To fix it, just add the shebang e.g., if it is a shell script; prepend #!/bin/sh
at the top of your script:
>>> with open('a','w') as f: f.write('#!/bin/sh\nexit 0')
...
>>> os.execl('./a', './a')
It executes exit 0
without any errors.
On POSIX systems, shell parses the command line i.e., your script won't see spaces around =
e.g., if script
is:
#!/usr/bin/env python
import sys
print(sys.argv)
then running it in the shell:
$ /usr/local/bin/script hostname = '<hostname>' -p LONGLIST
produces:
['/usr/local/bin/script', 'hostname', '=', '<hostname>', '-p', 'LONGLIST']
Note: no spaces around '='
. I've added quotes around <hostname>
to escape the redirection metacharacters <>
.
To emulate the shell command in Python, run:
from subprocess import check_call
cmd = ['/usr/local/bin/script', 'hostname', '=', '<hostname>', '-p', 'LONGLIST']
check_call(cmd)
Note: no shell=True
. And you don't need to escape <>
because no shell is run.
"Exec format error"
might indicate that your script
has invalid format, run:
$ file /usr/local/bin/script
to find out what it is. Compare the architecture with the output of:
$ uname -m
The simplest way is to drop the whole database and create it once again:
drop database db_name
create database db_name

If you want to check the version of a specific Kafka broker, run this CLI on the broker*
kafka-broker-api-versions.sh --bootstrap-server localhost:9092 --version
where localhost:9092
is the accessible <hostname|IP Address>:<port>
this API will check (localhost
can be used if it's the same host you're running this command on). Example of output:
2.4.0 (Commit:77a89fcf8d7fa018)

or with -P
that is explained in the Gradle documentation
If your segue exists in the storyboard with a segue identifier between your two views, you can just call it programmatically using:
performSegue(withIdentifier: "mySegueID", sender: nil)
For older versions:
performSegueWithIdentifier("mySegueID", sender: nil)
You could also do:
presentViewController(nextViewController, animated: true, completion: nil)
Or if you are in a Navigation controller:
self.navigationController?.pushViewController(nextViewController, animated: true)
Normal answer for this question if you really want to get something like content//media/external/video/media/18576
(e.g. for your video mp4 absolute path) and not just file///storage/emulated/0/DCIM/Camera/20141219_133139.mp4
:
MediaScannerConnection.scanFile(this,
new String[] { file.getAbsolutePath() }, null,
new MediaScannerConnection.OnScanCompletedListener() {
public void onScanCompleted(String path, Uri uri) {
Log.i("onScanCompleted", uri.getPath());
}
});
Accepted answer is wrong (cause it will not return content//media/external/video/media/*
)
Uri.fromFile(file).toString()
only returns something like file///storage/emulated/0/*
which is a simple absolute path of a file on the sdcard but with file//
prefix (scheme)
You can also get content
uri using MediaStore
database of Android
TEST (what returns Uri.fromFile
and what returns MediaScannerConnection
):
File videoFile = new File("/storage/emulated/0/video.mp4");
Log.i(TAG, Uri.fromFile(videoFile).toString());
MediaScannerConnection.scanFile(this, new String[] { videoFile.getAbsolutePath() }, null,
(path, uri) -> Log.i(TAG, uri.toString()));
Output:
I/Test: file:///storage/emulated/0/video.mp4
I/Test: content://media/external/video/media/268927
file.delete();
if the file doesn't exist, it will return false.
use app:cardUseCompatPadding="true"
inside your cardview.
For Example
<android.support.v7.widget.CardView
android:id="@+id/card_view"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginRight="@dimen/cardviewMarginRight"

If you want to do it using Pentaho DI, you can use "Modified JavaScript" Step and write the below function:
dateAdd(d1, "d", -7); // d1 is the current date and "d" is the date identifier
Check the image below: [Assuming current date is : 22 December 2014]
Hope it helps :)
In regular programming calculations, we don’t use float. If we ensure that the result range is within the range of float data type then we can choose a float data type for saving memory. Generally, we use double because of two reasons:-
Both float and double data types were designed especially for scientific calculations, where approximation errors are acceptable. If accuracy is the most prior concern then, it is recommended to use BigDecimal class instead of float or double data types. Source:- Float and double datatypes in Java
Use the -p flag and add /udp
suffix to the port number.
-p 53160:53160/udp
Full command
sudo docker run -p 53160:53160 \
-p 53160:53160/udp -p 58846:58846 \
-p 8112:8112 -t -i aostanin/deluge /start.sh
If you're running boot2docker on Mac, be sure to forward the same ports on boot2docker to your local machine.
You can also document that your container needs to receive UDP using EXPOSE in The Dockerfile
(EXPOSE does not publish the port):
EXPOSE 8285/udp
Here is a link with more Docker Networking info covered in the container docs: https://docs.docker.com/config/containers/container-networking/ (Courtesy of Old Pro in the comments)
You can simply wrap your list as a data.frame (data.frame is in fact a special kind of list). Here is an example:
mylist = list()
mylist[["a"]] = 1:10
mylist[["b"]] = letters[1:10]
write.table(as.data.frame(mylist),file="mylist.csv", quote=F,sep=",",row.names=F)
or alternatively you can use write.csv (a wrapper around write.table). For the conversion of the list , you can use both as.data.frame(mylist)
and data.frame(mylist)
.
To help in making a reproducible example, you can use functions like dput
on your data.
sometimes this error came beacause failed to compile in middlest of any build. The best way to try is by doing make clean and again make the whole code .
Try updating gradle dependency to 2.4. For that you need to go to
File -> Project Structure -> Project -> Gradle version
.
There you need to change from 2.2.1 to 2.4. Wait for new gradle version to be downloaded.
And you are ready to go.

You can pass your json Input as a POST request along with authorization header in this way
public static JSONObject getHttpConn(String json){
JSONObject jsonObject=null;
try {
HttpPost httpPost=new HttpPost("http://google.com/");
org.apache.http.client.HttpClient client = HttpClientBuilder.create().build();
StringEntity stringEntity=new StringEntity("d="+json);
httpPost.addHeader("content-type", "application/x-www-form-urlencoded");
String authorization="test:test@123";
String encodedAuth = "Basic " + Base64.encode(authorization.getBytes());
httpPost.addHeader("Authorization", security.get("Authorization"));
httpPost.setEntity(stringEntity);
HttpResponse reponse=client.execute(httpPost);
InputStream inputStream=reponse.getEntity().getContent();
String jsonResponse=IOUtils.toString(inputStream);
jsonObject=JSONObject.fromObject(jsonResponse);
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
} catch (ClientProtocolException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
return jsonObject;
}
This Method will return a json response.In same way you can use GET method
From How do I install a Python package with a .whl file? [sic], How do I install a Python package USING a .whl file ?
For all Windows platforms:
1) Download the .WHL package install file.
2) Make Sure path [C:\Progra~1\Python27\Scripts] is in the system PATH string. This is for using both [pip.exe] and [easy-install.exe].
3) Make sure the latest version of pip.EXE is now installed. At this time of posting:
pip.EXE --version
pip 9.0.1 from C:\PROGRA~1\Python27\lib\site-packages (python 2.7)
4) Run pip.EXE in an Admin command shell.
- Open an Admin privileged command shell.
> easy_install.EXE --upgrade pip
- Check the pip.EXE version:

As of TypeScript 2.0 you can include typings for native promises by including the following in your tsconfig.json
"compilerOptions": {
"lib": ["es5", "es2015.promise"]
}
This will include the promise declarations that comes with TypeScript without having to set the target to ES6.
I believe this is an issue with the target origin being https
. I suspect it is because your iFrame url is using http
instead of https
. Try changing the url of the file you are trying to embed to be https
.
For instance:
'//www.youtube.com/embed/' + id + '?showinfo=0&enablejsapi=1&origin=http://localhost:9000';
to be:
'https://www.youtube.com/embed/' + id + '?showinfo=0&enablejsapi=1&origin=http://localhost:9000';
Sourcetree 3.x has an option to accept gitLab. See here. I now use Sourcetree 3.0.15. In Settings, put your remote gitLab host and url, etc. If your existing git client version is not supported any more, the easiest way is perhaps to use Sourcetree embedded Git by Tools->Options->Git, in Git Version near the bottom, choose Embedded. A download may happen.
FFMpeg can do this by seeking to the given timestamp and extracting exactly one frame as an image, see for instance:
ffmpeg -i input_file.mp4 -ss 01:23:45 -vframes 1 output.jpg
Let's explain the options:
-i input file the path to the input file
-ss 01:23:45 seek the position to the specified timestamp
-vframes 1 only handle one video frame
output.jpg output filename, should have a well-known extension
The -ss
parameter accepts a value in the form HH:MM:SS[.xxx]
or as a number in seconds. If you need a percentage, you need to compute the video duration beforehand.
You can use git config
command to write a new rule to .git/config

And then just:
$ git fetch origin

Go to Preferences > Version Control > Git. Make sure SSH executable is set to “Native.” (If it's already so, switch it to “Built-in,” apply it, and then again switch back to “Native.”).
If this doesn't solve your issue, I would suggest to download a Git client such as GitHub client (free desktop app) and try to sync your project through the app. Then go back to IntelliJ and check if it works.
The necessary method is Mockito#verify:
public static <T> T verify(T mock,
VerificationMode mode)
mock
is your mocked object and mode
is the VerificationMode
that describes how the mock should be verified. Possible modes are:
verify(mock, times(5)).someMethod("was called five times");
verify(mock, never()).someMethod("was never called");
verify(mock, atLeastOnce()).someMethod("was called at least once");
verify(mock, atLeast(2)).someMethod("was called at least twice");
verify(mock, atMost(3)).someMethod("was called at most 3 times");
verify(mock, atLeast(0)).someMethod("was called any number of times"); // useful with captors
verify(mock, only()).someMethod("no other method has been called on the mock");
You'll need these static imports from the Mockito
class in order to use the verify
method and these verification modes:
import static org.mockito.Mockito.atLeast;
import static org.mockito.Mockito.atLeastOnce;
import static org.mockito.Mockito.atMost;
import static org.mockito.Mockito.never;
import static org.mockito.Mockito.only;
import static org.mockito.Mockito.times;
import static org.mockito.Mockito.verify;
So in your case the correct syntax will be:
Mockito.verify(mock, times(4)).send()
This verifies that the method send
was called 4 times on the mocked object. It will fail if it was called less or more than 4 times.
If you just want to check, if the method has been called once, then you don't need to pass a VerificationMode
. A simple
verify(mock).someMethod("was called once");
would be enough. It internally uses verify(mock, times(1)).someMethod("was called once");
.
It is possible to have multiple verification calls on the same mock to achieve a "between" verification. Mockito doesn't support something like this verify(mock, between(4,6)).someMethod("was called between 4 and 6 times");
, but we can write
verify(mock, atLeast(4)).someMethod("was called at least four times ...");
verify(mock, atMost(6)).someMethod("... and not more than six times");
instead, to get the same behaviour. The bounds are included, so the test case is green when the method was called 4, 5 or 6 times.
You can't solve it. Simply answer1.sum()==0
, and you can't perform a division by zero.
This happens because answer1
is the exponential of 2 very large, negative numbers, so that the result is rounded to zero.
nan
is returned in this case because of the division by zero.
Now to solve your problem you could:
scipy/numpy
function that does exactly what you want! Check out @Warren Weckesser answer.Here I explain how to do some math manipulation that helps on this problem. We have that for the numerator:
exp(-x)+exp(-y) = exp(log(exp(-x)+exp(-y)))
= exp(log(exp(-x)*[1+exp(-y+x)]))
= exp(log(exp(-x) + log(1+exp(-y+x)))
= exp(-x + log(1+exp(-y+x)))
where above x=3* 1089
and y=3* 1093
. Now, the argument of this exponential is
-x + log(1+exp(-y+x)) = -x + 6.1441934777474324e-06
For the denominator you could proceed similarly but obtain that log(1+exp(-z+k))
is already rounded to 0
, so that the argument of the exponential function at the denominator is simply rounded to -z=-3000
. You then have that your result is
exp(-x + log(1+exp(-y+x)))/exp(-z) = exp(-x+z+log(1+exp(-y+x))
= exp(-266.99999385580668)
which is already extremely close to the result that you would get if you were to keep only the 2 leading terms (i.e. the first number 1089
in the numerator and the first number 1000
at the denominator):
exp(3*(1089-1000))=exp(-267)
For the sake of it, let's see how close we are from the solution of Wolfram alpha (link):
Log[(exp[-3*1089]+exp[-3*1093])/([exp[-3*1000]+exp[-3*4443])] -> -266.999993855806522267194565420933791813296828742310997510523
The difference between this number and the exponent above is +1.7053025658242404e-13
, so the approximation we made at the denominator was fine.
The final result is
'exp(-266.99999385580668) = 1.1050349147204485e-116
From wolfram alpha is (link)
1.105034914720621496.. × 10^-116 # Wolfram alpha.
and again, it is safe to use numpy here too.
Bootstrap guys, we do it like this:
export default function RadioButton({ onChange, option }) {
const handleChange = event => {
onChange(event.target.value)
}
return (

<div className="custom-control custom-radio">
<input
type="radio"
id={ option.option }
name="customRadio"
className="custom-control-input"
onChange={ handleChange }
value = { option.id }
/>
<label
className="custom-control-label"
htmlFor={ option.option }
>
{ option.option }
</label>
</div>
</>
)
}

SOLUTION: (Notice: this solution is for datatables version 1.10.4 (at the moment) not legacy version).
CLARIFICATION Per the API documentation (1.10.15), the API can be accessed three ways:
The modern definition of DataTables (upper camel case):
var datatable = $( selector ).DataTable();
The legacy definition of DataTables (lower camel case):
var datatable = $( selector ).dataTable().api();
Using the new
syntax.
var datatable = new $.fn.dataTable.Api( selector );
Then load the data like so:
$.get('myUrl', function(newDataArray) {
datatable.clear();
datatable.rows.add(newDataArray);
datatable.draw();
});
Use draw(false)
to stay on the same page after the data update.
API references:

I had the same problem and solve it by just making header file public.
If you are working on multiple modules in your project. Then your header file needs to be public to be used in other parts of projects. What you need is to select that header file, and in project Utilities view. Change the file from Project/Private to Public. See image below:
The /P
switch allows you to set the value of a variable to a line of input entered by the user. Displays the specified promptString before reading the line of input. The promptString can be empty.
Two ways I've used it... first:
SET /P variable=
When batch file reaches this point (when left blank) it will halt and wait for user input. Input then becomes variable.
And second:
SET /P variable=<%temp%\filename.txt
Will set variable to contents (the first line) of the txt file. This method won't work unless the /P
is included. Both tested on Windows 8.1 Pro, but it's the same on 7 and 10.
If you know x
and y
are both strings, using ===
is not strictly necessary, but is still good practice.
Assuming both variables actually are strings, both operators will function identically. However, TS often allows you to pass an object that meets all the requirements of string
rather than an actual string, which may complicate things.
Given the possibility of confusion or changes in the future, your linter is probably correct in demanding ===
. Just go with that.
For those, who want to use Shell.Application.Namespace.Folder.CopyHere() and want to hide progress bars while copying, or use more options, the documentation is here:
https://docs.microsoft.com/en-us/windows/desktop/shell/folder-copyhere
To use powershell and hide progress bars and disable confirmations you can use code like this:
# We should create folder before using it for shell operations as it is required
New-Item -ItemType directory -Path "C:\destinationDir" -Force
$shell = New-Object -ComObject Shell.Application
$zip = $shell.Namespace("C:\archive.zip")
$items = $zip.items()
$shell.Namespace("C:\destinationDir").CopyHere($items, 1556)
Limitations of use of Shell.Application on windows core versions:
https://docs.microsoft.com/en-us/windows-server/administration/server-core/what-is-server-core
On windows core versions, by default the Microsoft-Windows-Server-Shell-Package is not installed, so shell.applicaton will not work.
note: Extracting archives this way will take a long time and can slow down windows gui
Here is my contribution.
I will not try to list all tools/libraries/plugins that exist to take advantage of Docker with Maven. Some answers have already done it.
instead of, I will focus on applications typology and the Dockerfile way.
Dockerfile
is really a simple and important concept of Docker (all known/public images rely on that) and I think that trying to avoid understanding and using Dockerfile
s is not necessarily the better way to enter in the Docker world.
1) For applications that we want to go on to run them on installed/standalone Java server (Tomcat, JBoss, etc...)
The road is harder and that is not the ideal target because that adds complexity (we have to manage/maintain the server) and it is less scalable and less fast than embedded servers in terms of build/deploy/undeploy.
But for legacy applications, that may considered as a first step.
Generally, the idea here is to define a Docker image for the server and to define an image per application to deploy.
The docker images for the applications produce the expected WAR/EAR but these are not executed as container and the image for the server application deploys the components produced by these images as deployed applications.
For huge applications (millions of line of codes) with a lot of legacy stuffs, and so hard to migrate to a full spring boot embedded solution, that is really a nice improvement.
I will not detail more that approach since that is for minor use cases of Docker but I wanted to expose the overall idea of that approach because I think that for developers facing to these complex cases, it is great to know that some doors are opened to integrate Docker.
2) For applications that embed/bootstrap the server themselves (Spring Boot with server embedded : Tomcat, Netty, Jetty...)
That is the ideal target with Docker.
I specified Spring Boot because that is a really nice framework to do that and that has also a very high level of maintainability but in theory we could use any other Java way to achieve that.
Generally, the idea here is to define a Docker image per application to deploy.
The docker images for the applications produce a JAR or a set of JAR/classes/configuration files and these start a JVM with the application (java command) when we create and start a container from these images.
For new applications or applications not too complex to migrate, that way has to be favored over standalone servers because that is the standard way and the most efficient way of using containers.
I will detail that approach.
1) Without Spring Boot
The idea is to create a fat jar with Maven (the maven assembly plugin and the maven shade plugin help for that) that contains both the compiled classes of the application and needed maven dependencies.
Then we can identify two cases :
if the application is a desktop or autonomous application (that doesn't need to be deployed on a server) : we could specify as CMD/ENTRYPOINT
in the Dockerfile
the java execution of the application : java -cp .:/fooPath/* -jar myJar
if the application is a server application, for example Tomcat, the idea is the same : to get a fat jar of the application and to run a JVM in the CMD/ENTRYPOINT
. But here with an important difference : we need to include some logic and specific libraries (org.apache.tomcat.embed
libraries and some others) that starts the embedded server when the main application is started.
We have a comprehensive guide on the heroku website.
For the first case (autonomous application), that is a straight and efficient way to use Docker.
For the second case (server application), that works but that is not straight, may be error prone and is not a very extensible model because you don't place your application in the frame of a mature framework such as Spring Boot that does many of these things for you and also provides a high level of extension.
But that has a advantage : you have a high level of freedom because you use directly the embedded Tomcat API.
2) With Spring Boot
At last, here we go.
That is both simple, efficient and very well documented.
There are really several approaches to make a Maven/Spring Boot application to run on Docker.
Exposing all of them would be long and maybe boring.
The best choice depends on your requirement.
But whatever the way, the build strategy in terms of docker layers looks like the same.
We want to use a multi stage build : one relying on Maven for the dependency resolution and for build and another one relying on JDK or JRE to start the application.
Build stage (Maven image) :
mvn dependency:resolve-plugins
chained to mvn dependency:resolve
may do the job but not always.package
execution to package the fat jar may rely on different artifacts/plugins and even for a same artifact/plugin, these may still pull a different version.
So a safer approach while potentially slower is resolving dependencies by executing exactly the mvn
command used to package the application (which will pull exactly dependencies that you are need) but by skipping the source compilation and by deleting the target folder to make the processing faster and to prevent any undesirable layer change detection for that step. Run stage (JDK or JRE image) :
Here two examples.
a) A simple way without cache for downloaded maven dependencies
Dockerfile :
########Maven build stage########
FROM maven:3.6-jdk-11 as maven_build
WORKDIR /app
#copy pom
COPY pom.xml .
#resolve maven dependencies
RUN mvn clean package -Dmaven.test.skip -Dmaven.main.skip -Dspring-boot.repackage.skip && rm -r target/
#copy source
COPY src ./src
# build the app (no dependency download here)
RUN mvn clean package -Dmaven.test.skip
# split the built app into multiple layers to improve layer rebuild
RUN mkdir -p target/docker-packaging && cd target/docker-packaging && jar -xf ../my-app*.jar
########JRE run stage########
FROM openjdk:11.0-jre
WORKDIR /app
#copy built app layer by layer
ARG DOCKER_PACKAGING_DIR=/app/target/docker-packaging
COPY --from=maven_build ${DOCKER_PACKAGING_DIR}/BOOT-INF/lib /app/lib
COPY --from=maven_build ${DOCKER_PACKAGING_DIR}/BOOT-INF/classes /app/classes
COPY --from=maven_build ${DOCKER_PACKAGING_DIR}/META-INF /app/META-INF
#run the app
CMD java -cp .:classes:lib/* \
-Djava.security.egd=file:/dev/./urandom \
foo.bar.MySpringBootApplication
Drawback of that solution ? Any changes in the pom.xml means re-creates the whole layer that download and stores the maven dependencies. That is generally not acceptable for applications with many dependencies (and Spring Boot pulls many dependencies), overall if you don't use a maven repository manager during the image build.
b) A more efficient way with cache for maven dependencies downloaded
The approach is here the same but maven dependencies downloads that are cached in the docker builder cache.
The cache operation relies on buildkit (experimental api of docker).
To enable buildkit, the env variable DOCKER_BUILDKIT=1 has to be set (you can do that where you want : .bashrc, command line, docker daemon json file...).
Dockerfile :
# syntax=docker/dockerfile:experimental
########Maven build stage########
FROM maven:3.6-jdk-11 as maven_build
WORKDIR /app

https://stackoverflow.com/a/37191719/75579 answer stopped working for me in Android 7 somehow. So I have to do it the manual way, so I want to share it.
Put this snippet of code in your ~/.bash_profile
or ~/.profile
file:
snap_screen() {
if [ $# -eq 0 ]
then
name="screenshot.png"
else
name="$1.png"
fi
adb shell screencap -p /sdcard/$name
adb pull /sdcard/$name
adb shell rm /sdcard/$name
curr_dir=pwd
echo "save to `pwd`/$name"
}
Run source ~/.bash_profile
or source ~/.profile
command,
Usage without specifying filename:
$ snap_screen

You have a few different options:
we could open html file from linux/unix by using firefox .html
Instead of returning a resultsArray
you return a promise for a results array and then then
that on the call site - this has the added benefit of the caller knowing the function is performing asynchronous I/O. Coding concurrency in JavaScript is based on that - you might want to read this question to get a broader idea:
function resultsByName(name)
{
var Card = Parse.Object.extend("Card");
var query = new Parse.Query(Card);
query.equalTo("name", name.toString());
var resultsArray = [];
return query.find({});
}
// later
resultsByName("Some Name").then(function(results){
// access results here by chaining to the returned promise
});
You can see more examples of using parse promises with queries in Parse's own blog post about it.
Another succinct way of doing this is pandas.DataFrame.clip.
For example:
import pandas as pd
In [20]: df = pd.DataFrame({'a': [-1, 100, -2]})
In [21]: df
Out[21]:
a
0 -1
1 100
2 -2
In [22]: df.clip(lower=0)
Out[22]:
a
0 0
1 100
2 0
There's also df.clip_lower(0)
.
Add this function to your helper file and simply call.
function getRawQuery($sql){
$query = str_replace(array('?'), array('\'%s\''), $sql->toSql());
$query = vsprintf($query, $sql->getBindings());
return $query;
}
Output: "select * from user where status = '1' order by id desc limit 25 offset 0"
Since the question asked for either jQuery or vanilla JS, here's an answer with vanilla JS.
I've added some CSS to the demo below to change the button's font color to red when its aria-expanded
is set to true
const button = document.querySelector('button');_x000D_
_x000D_
button.addEventListener('click', () => {_x000D_
button.ariaExpanded = !JSON.parse(button.ariaExpanded);_x000D_
})
_x000D_
button[aria-expanded="true"] {_x000D_
color: red;_x000D_
}
_x000D_
<button type="button" aria-expanded="false">Click me!</button>
_x000D_
vetrical-align: middle
did not work for me for some reason (and it was being applied). I used this:
table.vertical-align > tbody > tr > td {
display: flex;
align-items: center;
}
This is how graphql-js package detects promises:
function isPromise(value) {
return Boolean(value && typeof value.then === 'function');
}
value
is the returned value of your function. I'm using this code in my project and have no problem so far.
Unfortunately, vars files do not have include statements.
You can either put all the vars into the definitions
dictionary, or add the variables as another dictionary in the same file.
If you don't want to have them in the same file, you can include them at the playbook level by adding the vars file at the start of the play:
---
- hosts: myhosts
vars_files:
- default_step.yml
or in a task:
---
- hosts: myhosts
tasks:
- name: include default step variables
include_vars: default_step.yml
What I did not like with many answers is that it makes way too many system calls by writing to the file line per line. Imho it is best to join list with '\n' (line return) and then write it only once to the file:
mylist = ["abc", "def", "ghi"]
myfile = "file.txt"
with open(myfile, 'w') as f:
f.write("\n".join(mylist))
and then to open it and get your list again:
with open(myfile, 'r') as f:
mystring = f.read()
my_list = mystring.split("\n")
Adding to @Kirill Fuchs excellent solution and answering @StackUser's doubt - while starting the http-server, set the path till the app folder only, NOT till the html page!
http-server C:\location\to\app
and access index.html
under app
folder
We don't need to access the canvas context.
Implementing hednek in pure JS you would get canvas.setAttribute('style', 'background-color:#00F8')
. But my preferred method requires converting the kabab-case to camelCase.
canvas.style.backgroundColor = '#00F8'
The accepted answer is correct, but I found another cause if you're developing under ASP.NET with Visual Studio 2013 or higher and are sure you didn't make any synchronous ajax requests or define any scripts in the wrong place.
The solution is to disable the "Browser Link" feature by unchecking "Enable Browser Link" in the VS toolbar dropdown indicated by the little refresh icon pointing clockwise. As soon as you do this and reload the page, the warnings should stop!
This should only happen while debugging locally, but it's still nice to know the cause of the warnings.
For some unknown reason, Android Studio incorrectly adds the android() method in the top-level build.gradle file.
Just delete the method and it works for me.
android {
compileSdkVersion 21
buildToolsVersion '21.1.2'
}
I did not have enough reputation to comment and hence am adding a new answer.
Gasek answer is quite correct. Just one thing: if you are updating the .bash_profile
file or the /etc/profile
, those changes would be reflected only after you do a new login.
In case you want to set the env variable and then use it in subsequent tasks in the same playbook, consider adding those environment variables in the .bashrc
file.
I guess the reason behind this is the login and the non-login shells.
Ansible, while executing different tasks, reads the parameters from a .bashrc
file instead of the .bash_profile
or the /etc/profile
.
As an example, if I updated my path variable to include the custom binary in the .bash_profile
file of the respective user and then did a source of the file.
The next subsequent tasks won't recognize my command. However if you update in the .bashrc
file, the command would work.
- name: Adding the path in the bashrc files
lineinfile: dest=/root/.bashrc line='export PATH=$PATH:path-to-mysql/bin' insertafter='EOF' regexp='export PATH=\$PATH:path-to-mysql/bin' state=present
- - name: Source the bashrc file
shell: source /root/.bashrc
- name: Start the mysql client
shell: mysql -e "show databases";
This would work, but had I done it using profile files the mysql -e "show databases"
would have given an error.
- name: Adding the path in the Profile files
lineinfile: dest=/root/.bash_profile line='export PATH=$PATH:{{install_path}}/{{mysql_folder_name}}/bin' insertafter='EOF' regexp='export PATH=\$PATH:{{install_path}}/{{mysql_folder_name}}/bin' state=present
- name: Source the bash_profile file
shell: source /root/.bash_profile
- name: Start the mysql client
shell: mysql -e "show databases";
This one won't work, if we have all these tasks in the same playbook.
single line comment did not work for me inside a react dumb functional component, I have used file level disabling by adding /* eslint-disable insertEslintErrorDefinitionHere */
(normally if you are using vs code and getting eslint error, you can click on the line which gives error and a bulb would show up in vs code, right click on the light bulb and choose any disable option and vs code will do it for you.)
You may use jQuery in it like
$('#yesh').click(function(){
*****HERE GOES THE FUNCTION*****
});
Besides jQuery is easy to use.
You can make changes in colors etc using simple jQUery or Javascript.
Assuming that this is about OAuth 2.0 since it is about JWTs and refresh tokens...:
just like an access token, in principle a refresh token can be anything including all of the options you describe; a JWT could be used when the Authorization Server wants to be stateless or wants to enforce some sort of "proof-of-possession" semantics on to the client presenting it; note that a refresh token differs from an access token in that it is not presented to a Resource Server but only to the Authorization Server that issued it in the first place, so the self-contained validation optimization for JWTs-as-access-tokens does not hold for refresh tokens
that depends on the security/access of the database; if the database can be accessed by other parties/servers/applications/users, then yes (but your mileage may vary with where and how you store the encryption key...)
an Authorization Server may issue both access tokens and refresh tokens at the same time, depending on the grant that is used by the client to obtain them; the spec contains the details and options on each of the standardized grants
If you execute your Spring Boot application as a linux service (e.g. init.d script or similar), then you have the following option as well: Create a file called yourApplication.conf and put it next to your executable war/jar file. It's content should be something similar:
JAVA_OPTS="
-Djavax.net.ssl.trustStore=path-to-your-trustStore-file
-Djavax.net.ssl.trustStorePassword=yourCrazyPassword
"
Swift 3:
extension URL {
func getQueryItemValueForKey(key: String) -> String? {
guard let components = NSURLComponents(url: self, resolvingAgainstBaseURL: false) else {
return nil
}
guard let queryItems = components.queryItems else { return nil }
return queryItems.filter {
$0.name.lowercased() == key.lowercased()
}.first?.value
}
}
I used it to get the image name for UIImagePickerController
in func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any])
:
var originalFilename = ""
if let url = info[UIImagePickerControllerReferenceURL] as? URL, let imageIdentifier = url.getQueryItemValueForKey(key: "id") {
originalFilename = imageIdentifier + ".png"
print("file name : \(originalFilename)")
}
I don't know if maybe it's a difference in Excel version but this question is 6 years old and the accepted answer didn't help me so this is what I figured out:
Under Conditional Formatting > Manage Rules:
$A2<$B2
$B$2:$B$100
(assuming you have 100 rows)This worked for me in Excel 2016.

If you are developing to a modern browser. https://caniuse.com/#search=fit%20content
You can use:
width: fit-content;
Simple and dynamic solution (Swift 5):
extension FileManager {
class func directoryUrl() -> URL? {
let paths = FileManager.default.urls(for: .documentDirectory, in: .userDomainMask)
return paths.first
}
class func allRecordedData() -> [URL]? {
if let documentsUrl = FileManager.directoryUrl() {
do {
let directoryContents = try FileManager.default.contentsOfDirectory(at: documentsUrl, includingPropertiesForKeys: nil)
return directoryContents.filter{ $0.pathExtension == "m4a" }
} catch {
return nil
}
}
return nil
}}
R treats backslashes as escape values for character constants. (... and so do regular expressions. Hence the need for two backslashes when supplying a character argument for a pattern. The first one isn't actually a character, but rather it makes the second one into a character.) You can see how they are processed using cat
.
y <- "double quote: \", tab: \t, newline: \n, unicode point: \u20AC"
print(y)
## [1] "double quote: \", tab: \t, newline: \n, unicode point: €"
cat(y)
## double quote: ", tab: , newline:
## , unicode point: €
Further reading: Escaping a backslash with a backslash in R produces 2 backslashes in a string, not 1
To use special characters in a regular expression the simplest method is usually to escape them with a backslash, but as noted above, the backslash itself needs to be escaped.
grepl("\\[", "a[b")
## [1] TRUE
To match backslashes, you need to double escape, resulting in four backslashes.
grepl("\\\\", c("a\\b", "a\nb"))
## [1] TRUE FALSE
The rebus
package contains constants for each of the special characters to save you mistyping slashes.
library(rebus)
OPEN_BRACKET
## [1] "\\["
BACKSLASH
## [1] "\\\\"
For more examples see:
?SpecialCharacters
Your problem can be solved this way:
library(rebus)
grepl(OPEN_BRACKET, "a[b")
You can also wrap the special characters in square brackets to form a character class.
grepl("[?]", "a?b")
## [1] TRUE
Two of the special characters have special meaning inside character classes: \
and ^
.
Backslash still needs to be escaped even if it is inside a character class.
grepl("[\\\\]", c("a\\b", "a\nb"))
## [1] TRUE FALSE
Caret only needs to be escaped if it is directly after the opening square bracket.
grepl("[ ^]", "a^b") # matches spaces as well.
## [1] TRUE
grepl("[\\^]", "a^b")
## [1] TRUE
rebus
also lets you form a character class.
char_class("?")
## <regex> [?]
If you want to match all punctuation, you can use the [:punct:]
character class.
grepl("[[:punct:]]", c("//", "[", "(", "{", "?", "^", "$"))
## [1] TRUE TRUE TRUE TRUE TRUE TRUE TRUE
stringi
maps this to the Unicode General Category for punctuation, so its behaviour is slightly different.
stri_detect_regex(c("//", "[", "(", "{", "?", "^", "$"), "[[:punct:]]")
## [1] TRUE TRUE TRUE TRUE TRUE FALSE FALSE
You can also use the cross-platform syntax for accessing a UGC.
stri_detect_regex(c("//", "[", "(", "{", "?", "^", "$"), "\\p{P}")
## [1] TRUE TRUE TRUE TRUE TRUE FALSE FALSE
Placing characters between \\Q
and \\E
makes the regular expression engine treat them literally rather than as regular expressions.
grepl("\\Q.\\E", "a.b")
## [1] TRUE
rebus
lets you write literal blocks of regular expressions.
literal(".")
## <regex> \Q.\E
Regular expressions are not always the answer. If you want to match a fixed string then you can do, for example:
grepl("[", "a[b", fixed = TRUE)
stringr::str_detect("a[b", fixed("["))
stringi::stri_detect_fixed("a[b", "[")
Actual error
follow bellow two simple steps to fix.
Step 1:- update "Intel x86 Emulator Accelerator (HAXM installer)" Ref. bellow img
Step2:-
After installing the installer, you have to run it to install it on your system. Open the directory where your Android SDK is located. Go inside the extras\Intel\Hardware_Accelerated_Execution_Manager directory and you should see the intelhaxm-android.exe file.
If you got the error "This computer meets requirements for HAXM, but VT-x is not turned on..." during installation try to turn it on in your BIOS and check your antivirus software settings also. (Check this stackoverflow post). Thats it! its working for me.
