Regex working on regex101 but not in Vscode snippet

Question

I am struggling with a regex that works fine on regex101: https://regex101.com/r/Hhj2l9/1, but not in a vscode snippet for html.

From the following string: C:\folder0\folder1\folder2\libtest\folder3\folder4\folder5

I get the following results on regex101: libtest/libfolder3/libfolder4/folder5, which is what I want.

In my snippet:

lib${TM_DIRECTORY/(?:.*lib)?([^\\\\.*]*)\\\\/$1\\//g}

The result below in the html:

lib${TM_DIRECTORY/(?:.*lib)?([^\.*]*)\/\//g}

Has anyone an idea on how to make it work in a vscode snippet? Thanks a lot in advance.

You can use

"${TM_DIRECTORY/(?:.*[\\\\\\/]lib)?([^\\\\\\/]+)[\\\\\\/]/lib$1\\//g}"

Here,

(?:.*[\\\/]lib)? - matches an optional occurrence of any zero or more chars other than line break chars as many as possible, and then \ or / and lib
([^\\\\\\/]+) - Group 1 ($1): one or more chars other than \ and /
[\\\\\\/] - a / or \.

Great thanks a lot it works! Do you have any idea why my first attempt did not work? (I am curious to know, I am a bit of a beginner in regex)

@Benoit00 Your regex only added lib at the start of the text and the backslashes that match a literal backslash cannot appear immediately before the / regex delimiter char, so I put it into a character class, [...]. Also, note that [^\\\\.*] matches any char other than a \, . and *. I think . and * are typos here.
