Replace specific char from regular expression in VS Code

Question

I have this regex:

([A-Za-z])\'([A-Za-z])

This works, is for example for words like : d'utilisateur (in fr)

This regex select the d'u but I just want if the condition is met, select only '.

I don't know if this is posible and how.

This is for masive replace in VS Code in plain text.

Answer 1

In Visual Studio Code, you may still use your ([A-Za-z])'([A-Za-z]) and replace with 1ドル2ドル to remove this apostrophe.

However, this won't work for consecutive matches, and you will have to use a lookahead instead of the second group. So, to remove the apostrophes in between letters use

Find What: ([A-Za-z])'(?=[A-Za-z])
Replace With: 1ドル2ドル

If you need to replace with some other text, replace with 1ドル<MY_NEW_TEXT>.

Alternatively, you may use

\b'\b

However, this pattern will also match ' in between digits and _.

• Jordi Castillo: 1ドル2ドル works fine and it was that I was searching, but your regex and now is for learn not for need, don't works: regexr.com/4jn7n
• Wiktor Stribiżew: @JordiCastillo You are testing the regex with the JavaScript regex engine. Why? You say you are going to use the regex in Visual Studio. Use it there.
• Jordi Castillo: Yeah, i tested in both sites! And remember the VS Code works with Javascript engine
• Wiktor Stribiżew: @JordiCastillo you have both tags in the question, please remove the wrong one. Actually, VSCode is not using JS regex flavor. It is close to it, but not exactly the same. Also, the curent ECMAScript in Chrome supports all kinds of lookarounds and named groups.
• Jordi Castillo: I removed Visual studio I don't know if you refered to that
