In my case a previous run of my app from VS reserved the URL. I could see this by running in a console:
netsh http show urlacl
to delete this reservation i ran this in an elevated console:
netsh http delete urlacl http://127.0.0.1:10002/
I found these steps here solved my problem.
I'm using VS2013
You can use %x
or %X
or %p
; all of them are correct.
%x
, the address is given as lowercase, for example: a3bfbc4
%X
, the address is given as uppercase, for example: A3BFBC4
Both of these are correct.
If you use %x
or %X
it's considering six positions for the address, and if you use %p
it's considering eight positions for the address. For example:
If you are using Java 6 or higher you can use wildcards of this form:
java -classpath ".;c:\mylibs\*;c:\extlibs\*" MyApp
If you would like to add all subdirectories: lib\a\, lib\b\, lib\c\, there is no mechanism for this in except:
java -classpath ".;c:\lib\a\*;c:\lib\b\*;c:\lib\c\*" MyApp
There is nothing like lib\*\*
or lib\**
wildcard for the kind of job you want to be done.
Find the C file and Makefile implementation in below to meet your requirements
foo.c
main ()
{
int a = MAKE_DEFINE;
printf ("MAKE_DEFINE value:%d\n", a);
}
Makefile
all:
gcc -DMAKE_DEFINE=11 foo.c
VelocityEngine velocityEngin = new VelocityEngine();
velocityEngin.setProperty(RuntimeConstants.RESOURCE_LOADER, "classpath");
velocityEngin.setProperty("classpath.resource.loader.class", ClasspathResourceLoader.class.getName());
velocityEngin.init();
Template template = velocityEngin.getTemplate("nameOfTheTemplateFile.vtl");
you could use the above code to set the properties for velocity template. You can then give the name of the tempalte file when initializing the Template and it will find if it exists in the classpath.
All the above classes come from package org.apache.velocity*
It's also possible to customise your bootstrap build by using:
http://twitter.github.com/bootstrap/customize.html
All the plugins are included by default.
If you have installed more than one jdk version , uninstall the others and keep only the one in use. this worked for me. https://www.java.com/en/download/help/uninstall_java.xml
Remove all files not belonging to a repositiory (e.g. for a clean-build after switching a branch):
git status | xargs rm -rf
In PHP use .=
to append strings, and not +=
.
Why does this output 0? [...] Does PHP not like += with strings?
+=
is an arithmetic operator to add a number to another number. Using that operator with strings leads to an automatic type conversion. In the OP's case the strings have been converted to integers of the value 0
.
More about operators in PHP:
Use the literal escape character \
print("Here is, \"a quote\"")
The character basically means ignore the semantic context of my next charcter, and deal with it in its literal sense.
Try closing and reopening the file, then press Ctrl+F11
.
Verify that the name of the file you are running is the same as the name of the project you are working in, and that the name of the public class in that file is the same as the name of the project you are working in as well.
Otherwise, restart Eclipse. Let me know if this solves the problem! Otherwise, comment, and I'll try and help.
You could just use
DataGridView1.CurrentRow.Cells["ColumnName"].Value
You can just use:
> names(LIST)
[1] "A" "B"
Obviously the names of the first element is just
> names(LIST)[1]
[1] "A"
Yes you can use both. js bootstrap from twitter is a collection of jquery plugins. There shohuldn't be any conflict with jQuery UI.
Regarding bandwidth overload, it really depends on how you handle the requests to load all of your js files. if you really dont want to make multiple requests to the server to request for each file, just append them together and minimize. Or you probably can get rid of some js bootstrap plugins you dont need. it is very modular.
Here is an approach that doesn't require the use of a for
loop or defining an intermediate function or lambda function (and is also a one-liner). The method combines the following two ideas:
calling the iter()
built-in function with the optional sentinel argument, and
using the itertools
recipe for advancing an iterator n
steps (see the recipe for consume()
).
Putting these together, we get:
next(islice(iter(do, object()), 3, 3), None)
(The idea to pass object()
as the sentinel comes from this accepted Stack Overflow answer.)
And here is what this looks like from the interactive prompt:
>>> def do():
... print("called")
...
>>> next(itertools.islice(iter(do, object()), 3, 3), None)
called

Use the background-color property instead of the background property in your CSS.
So your code will look like this:
.fb-icon:hover {
background: blue;
}
if your tmp folder is relative to the directory where your code is running remove the /
in front of /tmp
.
So you just have tmp/test.jpg
in your code. This worked for me in a similar situation.
You can also simply change Apache Conf file to a different User Name and keep the group:
Apache Conf Applications/Xammp/etc/..
User 'User' = your user name in Mac os x.
Group daemon
sudo chown -R 'User':daemon ~/Sites/wordpress
sudo chmod -R g+w ~/Sites/wordpress
You can obtain all jQuery events using $._data($('[selector]')[0],'events'); change [selector] to what you need.
There is a plugin that gather all events attached by jQuery called eventsReport.
Also i write my own plugin that do this with better formatting.
But anyway it seems we can't gather events added by addEventListener method. May be we can wrap addEventListener call to store events added after our wrap call.
It seems the best way to see events added to an element with dev tools.
But you will not see delegated events there. So there we need jQuery eventsReport.
UPDATE: NOW We CAN see events added by addEventListener method SEE RIGHT ANSWER TO THIS QUESTION.
The current PHP Nightrain (4.0.0) is written in Python and it uses the wxPython libraries. So far wxPython has been working well to get PHP Nightrain where it is today but in order to push PHP Nightrain to its next level, we are introducing a sibling of PHP Nightrain, the PHPWebkit!
It's an update to PHP Nightrain.
Hehe. You have an implicit cast here, because you're telling printf
what type to expect.
Try this on for size instead:
unsigned int x = 0xFFFFFFFF;
int y = 0xFFFFFFFF;
if (x < 0)
printf("one\n");
else
printf("two\n");
if (y < 0)
printf("three\n");
else
printf("four\n");

you can use DateUtils class in org.apache.commons.lang3.time package
int addMinuteTime = 5;
Date targetTime = new Date(); //now
targetTime = DateUtils.addMinutes(targetTime, addMinuteTime); //add minute
Length of characters to be matched.
{n,m} n <= length <= m
{n} length == n
{n,} length >= n
And by default, the engine is greedy to match this pattern. For example, if the input is 123456789, \d{2,5} will match 12345 which is with length 5.
If you want the engine returns when length of 2 matched, use \d{2,5}?
This just allow positive integers.

Assuming you're using the cv2 version, that code finds the center of the image you want to rotate, calculates the transformation matrix and applies to the image.

I've used Blat ( http://www.blat.net/ ) for many years. It's a simple command line utility that can send email from command line. It's free and opensource.
You can use command like "Blat myfile.txt -to [email protected] -server smtp.domain.com -port 6000"
Here is some other software you can try to send email from command line (I've never used them):
http://caspian.dotconf.net/menu/Software/SendEmail/
http://www.petri.co.il/sendmail.htm
http://www.petri.co.il/software/mailsend105.zip
http://retired.beyondlogic.org/solutions/cmdlinemail/cmdlinemail.htm
Here ( http://www.petri.co.il/send_mail_from_script.htm ) you can find other various way of sending email from a VBS script, plus link to some of the mentioned software
The following VBScript code is taken from that page
Set objEmail = CreateObject("CDO.Message")
objEmail.From = "[email protected]"
objEmail.To = "[email protected]"
objEmail.Subject = "Server is down!"
objEmail.Textbody = "Server100 is no longer accessible over the network."
objEmail.Send
Save the file as something.vbs
Set Msg = CreateObject("CDO.Message")
With Msg
.To = "[email protected]"
.From = "[email protected]"
.Subject = "Hello"
.TextBody = "Just wanted to say hi."
.Send
End With
Save the file as something2.vbs
I think these VBS scripts use the windows default mail server, if present. I've not tested these scripts...
var isiOSSafari = (navigator.userAgent.match(/like Mac OS X/i)) ? true: false;
This code will be helpful for you
Model.update({
'type': "newuser"
}, {
$set: {
email: "[email protected]",
phoneNumber:"0123456789"
}
}, {
multi: true
},
function(err, result) {
console.log(result);
console.log(err);
})
You can use the below expression:
(^\d*\.?\d*[1-9]+\d*$)|(^[1-9]+\.?\d*$)
Valid entries: 1 1. 1.1 1.0 all positive real numbers
Invalid entries: all negative real numbers and 0 and 0.0
var str = "{ hello: 'world', places: ['Africa', 'America', 'Asia', 'Australia'] }" var fStr = str .replace(/([A-z]*)(:)/g, '"$1":') .replace(/'/g, "\"")
console.log(JSON.parse(fStr))

I found helpful information in the
Celery Project Workers Guide inspecting-workers
For my case, I am checking to see if Celery is running.
inspect_workers = task.app.control.inspect()
if inspect_workers.registered() is None:
state = 'FAILURE'
else:
state = str(task.state)
You can play with inspect to get your needs.
You add to the back state from the FragmentTransaction
and remove from the backstack using FragmentManager
pop methods:
FragmentManager manager = getActivity().getSupportFragmentManager();
FragmentTransaction trans = manager.beginTransaction();
trans.remove(myFrag);
trans.commit();
manager.popBackStack();
I think you want Any
:
if (myList.Any(str => str.Contains("Mdd LH")))
It's well worth becoming familiar with the LINQ standard query operators; I would usually use those rather than implementation-specific methods (such as List<T>.ConvertAll
) unless I was really bothered by the performance of a specific operator. (The implementation-specific methods can sometimes be more efficient by knowing the size of the result etc.)
Please try this answer.
SELECT * FROM `Yourtable` WHERE date(`dateField`) = '2018-09-25'
Serialize data:
setcookie('cookie', serialize($info), time()+3600);
Then unserialize data:
$data = unserialize($_COOKIE['cookie'], ["allowed_classes" => false]);
After data, $info and $data will have the same content.

Better to always download as your first try, the most recent version from the developer's site
I had the same error message you had, and by downloading the jar from the above (slf4j-1.7.2.tar.gz most recent version as of 2012OCT13), untarring, uncompressing, adding 2 jars to build path in eclipse (or adding to classpath in comand line):
slf4j-api-1.7.2.jar

Runnable
is often used to provide the code that a thread should run, but Runnable
itself has nothing to do with threads. It's just an object with a run()
method.
In Android, the Handler
class can be used to ask the framework to run some code later on the same thread, rather than on a different one. Runnable
is used to provide the code that should run later.
import requests
site_request = requests.get("https://abhiunix.in")
site_response = str(site_request.content)
print(site_response)
As apps run in the background anyway. I’m assuming what your really asking is how do you make apps do stuff in the background. The solution below will make your app do stuff in the background after opening the app and after the system has rebooted.
Below, I’ve added a link to a fully working example (in the form of an Android Studio Project)
This subject seems to be out of the scope of the Android docs, and there doesn’t seem to be any one comprehensive doc on this. The information is spread across a few docs.
The following docs tell you indirectly how to do this: https://developer.android.com/reference/android/app/Service.html
https://developer.android.com/reference/android/content/BroadcastReceiver.html
https://developer.android.com/guide/components/bound-services.html
In the interests of getting your usage requirements correct, the important part of this above doc to read carefully is: #Binder, #Messenger and the components link below:
https://developer.android.com/guide/components/aidl.html
Here is the link to a fully working example (in Android Studio format): http://developersfound.com/BackgroundServiceDemo.zip
This project will start an Activity which binds to a service; implementing the AIDL.
This project is also useful to re-factor for the purpose of IPC across different apps.
This project is also developed to start automatically when Android restarts (provided the app has been run at least one after installation and app is not installed on SD card)
When this app/project runs after reboot, it dynamically uses a transparent view to make it look like no app has started but the service of the associated app starts cleanly.
This code is written in such a way that it’s very easy to tweak to simulate a scheduled service.
This project is developed in accordance to the above docs and is subsequently a clean solution.
There is however a part of this project which is not clean being: I have not found a way to start a service on reboot without using an Activity. If any of you guys reading this post have a clean way to do this please post a comment.
Thanks Hong, that was exactly the problem I was running into. The error you get suggests that the number of rows is wrong, but the problem is actually that the model has been trained using a command that ends up with the wrong names for parameters.
This is really a critical detail that is entirely non-obvious for lm and so on. Some of the tutorial make reference to doing lines like lm(olive$Area@olive$Palmitic)
- ending up with variable names of olive$Area NOT Area, so creating an entry using anewdata<-data.frame(Palmitic=2)
can't then be used. If you use lm(Area@Palmitic,data=olive)
then the variable names are right and prediction works.
The real problem is that the error message does not indicate the problem at all:
Warning message: 'anewdata' had 1 rows but variable(s) found to have X rows
I combined the efficiency of Mark's solution - so I do not have to .Clone
the entire DataTable - with generics and extensibility, so I can define my own conversion function. This is what I ended up with:
/// <summary>
/// Converts a column in a DataTable to another type using a user-defined converter function.
/// </summary>
/// <param name="dt">The source table.</param>
/// <param name="columnName">The name of the column to convert.</param>
/// <param name="valueConverter">Converter function that converts existing values to the new type.</param>
/// <typeparam name="TTargetType">The target column type.</typeparam>
public static void ConvertColumnTypeTo<TTargetType>(this DataTable dt, string columnName, Func<object, TTargetType> valueConverter)
{
var newType = typeof(TTargetType);
DataColumn dc = new DataColumn(columnName + "_new", newType);
// Add the new column which has the new type, and move it to the ordinal of the old column
int ordinal = dt.Columns[columnName].Ordinal;
dt.Columns.Add(dc);
dc.SetOrdinal(ordinal);
// Get and convert the values of the old column, and insert them into the new
foreach (DataRow dr in dt.Rows)
{
dr[dc.ColumnName] = valueConverter(dr[columnName]);
}
// Remove the old column
dt.Columns.Remove(columnName);
// Give the new column the old column's name
dc.ColumnName = columnName;
}
This way, usage is a lot more straightforward, while also customizable:
DataTable someDt = CreateSomeDataTable();
// Assume ColumnName is an int column which we want to convert to a string one.
someDt.ConvertColumnTypeTo<string>('ColumnName', raw => raw.ToString());
public String millsToDateFormat(long mills) {
Date date = new Date(mills);
DateFormat formatter = new SimpleDateFormat("HH:mm:ss");
String dateFormatted = formatter.format(date);
return dateFormatted; //note that it will give you the time in GMT+0
}
The printf() family of functions uses %
character as a placeholder. When a %
is encountered, printf reads the characters following the %
to determine what to do:
%s - Take the next argument and print it as a string
%d - Take the next argument and print it as an int
See this Wikipedia article for a nice picture: printf format string
The \n
at the end of the string is for a newline/carriage-return character.
Try this:
<?php
$servername = "localhost";
$database = "database";
$username = "user";
$password = "password";
// Create connection
$conn = new mysqli($servername, $username, $password, $database);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
echo "Connected successfully";
?>
There are several problems here:
The newdata
argument of predict()
needs a predictor variable. You should thus pass it values for Coupon
, instead of Total
, which is the response variable in your model.
The predictor variable needs to be passed in as a named column in a data frame, so that
predict()
knows what the numbers its been handed represent. (The need for this becomes clear when you consider more complicated models, having more than one predictor variable).
For this to work, your original call should pass df
in through the data
argument, rather than using it directly in your formula. (This way, the name of the column in newdata
will be able to match the name on the RHS of the formula).
With those changes incorporated, this will work:
model <- lm(Total ~ Coupon, data=df)
new <- data.frame(Coupon = df$Coupon)
predict(model, newdata = new, interval="confidence")
How to download and install if you have SUSE. As an example I am downloading the tablefunc module so I can use crosstab. I have PostgreSQL 9.6.1.
right-click desktop, terminal, type:
sudo zypper in postgreql-contrib
Enter credentials, continue by typing:
y
Run query (I ran mine from pgAdminIII):
CREATE EXTENSION tablefunc;
You should now have the crosstab
function.
I did not have to restart.
Instead of a functor as Mehrdad proposed, you could use a Lambda function.
sort(numbers.begin(), numbers.end(), [](const int a, const int b) {return a > b; });

numpy.ndarray
can contain any type of element, e.g. int
, float
, string
etc. Check the type an do a conversion if neccessary.
If you need a weak reference to the cell value:
object field = d.Rows[0][3]
or
object field = d.Rows[0].ItemArray[3]
Should do it
If you need a strongly typed reference (string in your case) you can use the DataRowExtensions.Field extension method:
string field = d.Rows[0].Field<string>(3);
(make sure System.Data is in listed in the namespaces in this case)
Indexes are 0 based so we first access the first row (0) and then the 4th column in this row (3)

I was just noticing my instance of IISExpress wasn't serving woff files, so I wen't searching (Found this) and then found:
http://www.tomasmcguinness.com/2011/07/06/adding-support-for-svg-to-iis-express/
I suppose my install has support for SVG since I haven't had issue with that. But the instructions are trivially modifiable for woff:
Run the command:
appcmd set config /section:staticContent /+[fileExtension='woff',mimeType='application/x-woff']
Solved my problem, and I didn't have to mess with some crummy config (like I had to to add support for the PUT
and DELETE
verbs). Yay!
MSTest does not support that feature, but you can implement your own attribute to achieve that.

This is typically done manually by choosing the appropriate bits from the vector and then appending 0s.

I think you are wrapping your exception in another exception (which isn't in your code above). If you try out this code:
public static void main(String[] args) {
try {
throw new RuntimeException("Cannot move file");
} catch (Exception ex) {
JOptionPane.showMessageDialog(null, "Error: " + ex.getMessage());
}
}
...you will see a popup that says exactly what you want.
However, to solve your problem (the wrapped exception) you need get to the "root" exception with the "correct" message. To do this you need to create a own recursive method getRootCause
:
public static void main(String[] args) {
try {
throw new Exception(new RuntimeException("Cannot move file"));
} catch (Exception ex) {
JOptionPane.showMessageDialog(null,
"Error: " + getRootCause(ex).getMessage());
}
}
public static Throwable getRootCause(Throwable throwable) {
if (throwable.getCause() != null)
return getRootCause(throwable.getCause());
return throwable;
}
Note: Unwrapping exceptions like this however, sort of breaks the abstractions. I encourage you to find out why the exception is wrapped and ask yourself if it makes sense.
For a long time, CMake had the add_definitions
command for this purpose. However, recently the command has been superseded by a more fine grained approach (separate commands for compile definitions, include directories, and compiler options).
An example using the new add_compile_definitions:
add_compile_definitions(OPENCV_VERSION=${OpenCV_VERSION})
add_compile_definitions(WITH_OPENCV2)
Or:
add_compile_definitions(OPENCV_VERSION=${OpenCV_VERSION} WITH_OPENCV2)
The good part about this is that it circumvents the shabby trickery CMake has in place for add_definitions
. CMake is such a shabby system, but they are finally finding some sanity.
Find more explanation on which commands to use for compiler flags here: https://cmake.org/cmake/help/latest/command/add_definitions.html
Likewise, you can do this per-target as explained in Jim Hunziker's answer.
If the difference between endTime and startTime is greater than or equal to 60 Minutes , the statement:endTime.Subtract(startTime).Minutes;
will always return (minutesDifference % 60)
. Obviously which is not desired when we are only talking about minutes (not hours here).
Here are some of the ways if you want to get total number of minutes
(in different typecasts):
// Default value that is returned is of type *double*
double double_minutes = endTime.Subtract(startTime).TotalMinutes;
int integer_minutes = (int)endTime.Subtract(startTime).TotalMinutes;
long long_minutes = (long)endTime.Subtract(startTime).TotalMinutes;
string string_minutes = (string)endTime.Subtract(startTime).TotalMinutes;
Select constraint_name,constraint_type from user_constraints where table_name** **= ‘TABLE_NAME’ ;
(This will list the primary key and then)
Select column_name,position from user_cons_cloumns where constraint_name=’PK_XYZ’;
(This will give you the column, here PK_XYZ is the primay key name)
Something like this
String myTime = "14:10";
SimpleDateFormat df = new SimpleDateFormat("HH:mm");
Date d = df.parse(myTime);
Calendar cal = Calendar.getInstance();
cal.setTime(d);
cal.add(Calendar.MINUTE, 10);
String newTime = df.format(cal.getTime());
As a fair warning there might be some problems if daylight savings time is involved in this 10 minute period.
Using Java createBitmap()
method you can pass the degrees.
Bitmap bInput /*your input bitmap*/, bOutput;
float degrees = 45; //rotation degree
Matrix matrix = new Matrix();
matrix.setRotate(degrees);
bOutput = Bitmap.createBitmap(bInput, 0, 0, bInput.getWidth(), bInput.getHeight(), matrix, true);

You can do something like this:
Using search will return a SRE_match object, if it matches your search string.
>>> import re
>>> m = re.search(u'ba[r|z|d]', 'bar')
>>> m
<_sre.SRE_Match object at 0x02027288>
>>> m.group()
'bar'
>>> n = re.search(u'ba[r|z|d]', 'bas')
>>> n.group()
If not, it will return None
Traceback (most recent call last):
File "<pyshell#17>", line 1, in <module>
n.group()
AttributeError: 'NoneType' object has no attribute 'group'
And just to print it to demonstrate again:
>>> print n
None
The best workaround that I found creating a new Project from scratch, then import all the source files with the code. My project was not so complicated so I had no problem from there.
If you need just positive integer numbers and don't need leading zeros (e.g. "0001234" or "00"):
var reg = /^(?:[1-9]\d*|\d)$/;
Just use basename
:
echo `basename "$filename"`
The quotes are needed in case $filename contains e.g. spaces.

benefit.indexOf(map4)
It either returns an index or -1 if the items is not found.
I strongly recommend wrapping the map in some object and use generics if possible.

Notice the space between ':' and '-', otherwise it means different:
${var:-word} If var is null or unset,
word is substituted for var. The value of var does not change.${var:+word} If var is set,
word is substituted for var. The value of var does not change.
Which is described in:Unix / Linux - Shell Substitution
The basic answer to the question in the title is eval(as.symbol(variable_name_as_string))
as Josh O'Brien uses. e.g.
var.name = "x"
assign(var.name, 5)
eval(as.symbol(var.name)) # outputs 5
Or more simply:
get(var.name) # 5
Neither way is necessarily correct or incorrect, they are just two different kinds of class elements:
__init__
method are static elements; they belong to the class.__init__
method are elements of the object (self
); they don't belong to the class.You'll see it more clearly with some code:
class MyClass:
static_elem = 123
def __init__(self):
self.object_elem = 456
c1 = MyClass()
c2 = MyClass()
# Initial values of both elements
>>> print c1.static_elem, c1.object_elem
123 456
>>> print c2.static_elem, c2.object_elem
123 456
# Nothing new so far ...
# Let's try changing the static element
MyClass.static_elem = 999
>>> print c1.static_elem, c1.object_elem
999 456
>>> print c2.static_elem, c2.object_elem
999 456
# Now, let's try changing the object element
c1.object_elem = 888
>>> print c1.static_elem, c1.object_elem
999 888
>>> print c2.static_elem, c2.object_elem
999 456
As you can see, when we changed the class element, it changed for both objects. But, when we changed the object element, the other object remained unchanged.
Gmail started basic support for style tags in the head area. Found nothing official yet but you can easily try it yourself.
It seems to ignore class and id selectors but basic element selectors work.
<!doctype html>
<html>
<head>
<style type="text/css">
p{font-family:Tahoma,sans-serif;font-size:12px;margin:0}
</style>
</head>
<body>
<p>Email content here</p>
</body>
</html>
it will create a style tag in its own head area limited to the div containing the mail body
<style>div.m14623dcb877eef15 p{font-family:Tahoma,sans-serif;font-size:12px;margin:0}</style>
Here is an example on how to configure Jetty's websocket timeout (the most likely culprit) using WebSocketServlet (in scala, sorry, but the syntax is pretty much the same).
import javax.servlet.annotation.WebServlet
import org.eclipse.jetty.websocket.servlet.{WebSocketServletFactory, WebSocketServlet}
@WebServlet(name = "WebSocket Servlet")
class WebsocketServlet extends WebSocketServlet {
override def configure(factory: WebSocketServletFactory): Unit = {
factory.getPolicy.setIdleTimeout(1000 * 3600)
factory.register(classOf[ClientWebsocket])
}
}
On many source packages (e.g. for most GNU software), the building system may know about the DESTDIR
make variable, so you can often do:
make install DESTDIR=/tmp/myinst/
sudo cp -va /tmp/myinst/ /
The advantage of this approach is that make install
don't need to run as root, so you cannot end up with files compiled as root (or root-owned files in your build tree).
From the command-line:
echo '{"one":1,"two":2}' | python -mjson.tool
which outputs:
{
"one": 1,
"two": 2
}
Programmtically, the Python manual describes pretty-printing JSON:
>>> import json
>>> print json.dumps({'4': 5, '6': 7}, sort_keys=True, indent=4)
{
"4": 5,
"6": 7
}
XmlDocument doc = new XmlDocument();
doc.Load("MonFichierXML.xml");
XmlNode node = doc.SelectSingleNode("Magasin");
XmlNodeList prop = node.SelectNodes("Items");
foreach (XmlNode item in prop)
{
items Temp = new items();
Temp.AssignInfo(item);
lstitems.Add(Temp);
}
If you have GNU coreutils installed, consider %!unexpand --first-only
or for 4-space tabs, consider %!unexpand -t 4 --first-only
(--first-only
is present just in case you were accidentally invoking unexpand
with --all
).
Note that this will only replace the spaces preceding the prescribed tab stops, not the spaces that follow them; you will see no visual difference in vim unless you display tabs more literally; for example, my ~/.vimrc
contains set list listchars=tab:??
(I suspect this is why you thought unexpand
didn't work).
Suppose you have a database field created_at Where you take value from timestamp. You want to search by Year & Month from created_at date.
YEAR(date(created_at))=2019 AND MONTH(date(created_at))=2
