How to get the base directory in visual studio code snippet?

Question

I am trying to get the file current directory in a snippet for visual studio code.

VSCode has a variable: TM_DIRECTORY, which is the fullpath.

eg:

{folder: "$TM_DIRECTORY"}

would be replaced by

{folder: "/Volumes/my-project-path/ParentFolder/MyFolder"}

But I want only MyFolder.

Normally, we can use a transform as indicated in the docs. Sublime Text works in the same way. But for as much as I try, the snippet simply outputs the whole regex.

Could someone answer with the magical variable/transform? :)

Answer 1

Ok, finally found it.

${TM_DIRECTORY/^.+\\/(.*)$/$1/} gives the base directory.

The part I didn't get was the "double escape" of the directory separator / -> \\/.

Nevermind found it too: ${TM_DIRECTORY/^.+\\\\(.*)$/$1/} – Luker

I dont get how vscode snippets are working but definitely it differ from regex101. I tried this ${TM_DIRECTORY/(\\w+)$/$1/} and it just doesnt work, thought I expected it to take last word before end of string as it does here regex101.com/r/kc7oNF/1 – Pending

Answer 2

This supports Windows & Unix:

${TM_DIRECTORY/^.+[\\/\\\\]+(.*)$/$1/}

Answer 3

I wanted to add that in Windows the code above will print the entire directory.

You need to add a quadruple backslash vs the forward-slash:

${TM_DIRECTORY/^.+\\\\(.*)$/$1/}

What is this language called? I'd like to understand it to use it on my own. – Legg

@Legg I think it's just plain JavaScript. It's just escaping the strings due to parsing. – Qp

Plain JS? I tried using this snippet in Neovim, and its not working at all. I assumed it was some kind of regex. What do you mean by plain JS? – Legg

@Legg are you using Linux/WSL or Windows? That code works only for Windows. – Qp

@Legg I'm sorry, it's not plain JavaScript. VSCode follows the TextMate syntax macromates.com/manual/en/snippets. You can learn more about it here: code.visualstudio.com/docs/editor/userdefinedsnippets – Qp

Big help! Thanks! I'm on linux btw, is there some keyword I should look out for? – Legg
