This is a feature I use with some frequency, but not frequently enough that I remember the pattern when I need it. Therefore, I am writing this art...

What if I need to replace something with $? For example, replace '$var' with '$this->var=$var', the regex to search is easy, the problem is the replacement, I tries with '$this->$1 = $$1', it does not work properly. So how do we go about it?
OK. I see a couple of things going on here.
First, you state you are using '$var', for replacement, this should be '(\$[a-zA-Z]*)'.
Second, to use '$this->$1 = $$1' as a pattern for replacement ...
Article written and posted ... here: dev.to/rfornal/vs-code-search-and-...
Having provided a reply, I think I'll write this up as a separate article for clarity. I'll post here when it's complete ... probably in the next day or two. Thanks for the GOOD question!
that's amazing, thanks very much that's helped a lot
Glad it helped!
In case you need to replace something like "NumberInt(2018)" with 2018, e.g. in mongodb json files, this would be the find pattern "NumberInt((.?)(\d+))" with the replace "$2". Or this one "ISODate((.?)(.+))" => $2 to transform "ISODate("2021-06-13T20:00:00.000+0000")" to "2021-06-13T20:00:00.000+0000". Cheers!
Is that any way to replace regex expression with vsCode extension API?
I'm not quite sure what this question is.
While using vs code you can find and replace some word using with regex. We are using this usage in our daily lives. But my question is Can I do it with vscode API. I want to make a vscode extension with this endpoint So if it exists
That's a question I'm not able to answer. I know VS Code by usage as a developer ... not by working on VS Code Extensions. I would assume there would be a way to interact with it via API. You might have to come up with an example and contact the team working on VS Code (it is Open Source, so shouldn't be an issue).
Where is the option for Perl based PCRE2 engine? I looked in the settings but didn't see it.
OK. I will start by saying that I am not an expert here.
It looks like VS Code, at one time, had a setting to use PCRE2. It has since been deprecated, and PCRE2 is automatically used as a fallback when the default engine doesn't support a feature.
Found this information HERE.
this is really helpful. I can easily understand and even apply in a different situation
Thanks for this! First time I've seen this explained clearly.
Took me a while to figure that we actually "declare" a param in our regex with ( and ).
Thanks! By helping yourself you also helped others.
I’ll go back and look at the article to see if I can clarify that better.
Wow thats nice, using $1 its what I was looking for
