I am trying to export a csv using react-csv. The documentation says that I should be able to modify the enclosing character with an enclosingCharacter prop, but it doesn't seem to make a difference when I set it. It always uses a quotation mark as the enclosing character. I've tried single quotes, false, null. Nothing works. Ideally, I'd like for there to be no enclosing characters and just use commas for the delimiter. What am I doing wrong?
<CSVLink
data={this.state.csvData}
filename="sample.csv"
enclosingCharacter={`'`}
/>
Current output looks like this: "data1","data2","data3"
Desired output should look like this: data1,data2,data3

I would like to create a User Snipper in VS Code that is a combination of variables and plaint text. This can typically be achieved by combining variables and plain text with a whitespace between then. But I would like to ad a variable next to a text without a whitespace.
For Example, I would like to create the current timestamp like this:
2022-02-19T21:02:24-0530
Below is what I tried
$CURRENT_YEAR-$CURRENT_MONTH-$CURRENT_DATET$CURRENT_HOUR:$CURRENT_MINUTE:$CURRENT_SECOND-0530
Notice the T in between $CURRENT_DATE & $CURRENT_HOUR
OUTPUT:
2022-02-CURRENT_DATET21:06:12-0530
You can add $ symbol before the plain-text you want to add.
In this case, you need at add $T instead of T
$CURRENT_YEAR-$CURRENT_MONTH-$CURRENT_DATE$T$CURRENT_HOUR:$CURRENT_MINUTE:$CURRENT_SECOND-0530
Note that $T will get considered as a placeholder, and it will be the last item selected while tabbing through the inserted snippet.
I'm creating a javascript regex to match queries in a search engine string. I am having a problem with alternation. I have the following regex:
.*baidu.com.*[/?].*wd{1}=
I want to be able to match strings that have the string 'word' or 'qw' in addition to 'wd', but everything I try is unsuccessful. I thought I would be able to do something like the following:
.*baidu.com.*[/?].*[wd|word|qw]{1}=
but it does not seem to work.
replace [wd|word|qw] with (wd|word|qw) or (?:wd|word|qw).
[] denotes character sets, () denotes logical groupings.
Your expression:
.*baidu.com.*[/?].*[wd|word|qw]{1}=
does need a few changes, including [wd|word|qw] to (wd|word|qw) and getting rid of the redundant {1}, like so:
.*baidu.com.*[/?].*(wd|word|qw)=
But you also need to understand that the first part of your expression (.*baidu.com.*[/?].*) will match baidu.com hello what spelling/handle????????? or hbaidu-com/ or even something like lkas----jhdf lkja$##!3hdsfbaidugcomlaksjhdf.[($?lakshf, because the dot (.) matches any character except newlines... to match a literal dot, you have to escape it with a backslash (like \.)
There are several approaches you could take to match things in a URL, but we could help you more if you tell us what you are trying to do or accomplish - perhaps regex is not the best solution or (EDIT) only part of the best solution?
I have such a code ng-init="validationRegex = '#RegularExpression.expression'" where RegularExpression.expression is c# string variable = "(\w+\/|\w+\\)+(\w+)\.\w+". I want to pass variable value to angular controller using ng-init. But in the end I get (w+/|w+\)+(w+).w+. How can I get right value?
I assume that your C# code is actually: #"(\w+\/|\w+\\)+(\w+)\.\w+". The # avoids needing the evil escaped escape.
You will likely need to use the evil escaped escape in this case. Note that you don't need to escape the / if you are putting it directly in a string (if you are using it how I think you are). You can also use braces to minimize the escaping. So you can take this regex:
(\w+/|\w+\\)+(\w+)[.]\w+
and pass it through regex planet to get this:
"(\\w+/|\\w+\\\\)+(\\w+)[.]\\w+"
I would not recommend manual conversion since you already have an escaped backslash.
Double escape the string using:
#RegularExpression.expression.Replace(#"\", #"\\")
When it comes through on the JavaScript side it will be singly-escaped again.
So my HTML passes a file into AngularJS, and it is named as myFile.
So I use:
console.log($scope.myFile.type);
and it prints out 'application/pdf'.
But when I use this line:
if ($scope.myFile.type == 'application/pdf'){
// some stuff here
}
or
($scope.myFile.type == {'image/jpeg': fileMimeType})
Those will not ever be equal to true. I have no idea how to run this comparison anymore, and would appreciate snippets that would allow me to somehow create this comparison.
Thanks.
I wish i could make comments, but alas i do not have enough points. Did you try console.log( typeof $scope.myFile.type); to make sure it was a string? Also did the output itself have single quotes in it? because if it does have the quotes in it you'll either need to strip those or compare with the quotes in your string.
The value of the second parameter of the markup extension I am using is a string containing some commas and I don't want those commas to be interpreted as parameter separators by the xaml interpreter / parser, but that the whole string as such including the commas is used as value.
Here is an example:
<SomeControl SomeProperty="{Wpf:MyExtension MyFirstParameter,
MySecondParameter, being a string, containing some commas.}" />
Google didn't help, I found some similar issues but none apply to this problem:

You can use single quotes to encapsulate a string; so your mark-up should look something like:
<SomeControl SomeProperty="{Wpf:MyExtension MyFirstParameter,
'MySecondParameter, being a string, containing some commas.'}" />
I'm not sure whether you will also need the {} escape sequence mark-up.
