Replace string with carriage return line feed with regular expression in Visual Studio Code

Question

In Visual Studio Code, I would like to replace, in all project files, all instructions log.info NOT equal to:

log.info(
                `DEBUG other strings...
);

with nothing (I want to delete them in all files); for example, this log.info should be removed:

log.info(
                `remove this instruction!!!
);

but not this (it has DEBUG has first word):

log.info(
                `DEBUG other strings...
);

Pay attention, log.info() could be also on a single line, for example:

log.info(`remove this instruction!!!);<br>
log.info(`DEBUG other strings...);<br>

I have tried this, with no result:

log.(info|warn|error)\([\n|\s]`*(?!DEBUG).*\)

Perhaps like this `log\.info\((?:(?!DEBUG|\);)[\s\S])*\);` https://regex101.com/r/wan9rr/1 — The fourth bird, Apr 03 '20 at 14:20
@Thefourthbird In VSCode, [any char is matched](https://stackoverflow.com/a/41151078/3832970) with `[\w\W]` or `[\s\S\r]` or `[^\r]`. — Wiktor Stribiżew, Apr 03 '20 at 14:26
@WiktorStribiżew You are right! Now it works :-) `log\.info\((?:(?!DEBUG|\);)[\w\W])*\);` https://regex101.com/r/os9kqm/1 — The fourth bird, Apr 03 '20 at 14:28
Well, I'd suggest ``\blog\.(?:info|warn|error)\((?!\s*`DEBUG\b)[\w\W]*?\);`` — Wiktor Stribiżew, Apr 03 '20 at 14:29
@Yellow75 Should `DEBUG` always be the first word after the opening parenthesis? — The fourth bird, Apr 03 '20 at 14:40
@The fourth bird: yes, `DEBUG` is always the first word after opening parenthesis and backtick. — user1, Apr 03 '20 at 14:41
@ Wiktor Stribiżew: you are right! Thanks Wiktor and everybody. — user1, Apr 03 '20 at 14:44

You may use

\blog\.(?:info|warn|error)\((?!\s*`DEBUG\b)[\w\W]*?\);

Details

\b - a word boundary
log\. - log. string
(?:info|warn|error) - either info, warn or error
\( - a ( char
(?!\s*DEBUG\b)- a negative lookahead that fails the match if, immediately to the right of the current location, there is 0+ whitespaces, a backtick,DEBUG` as whole word
[\w\W]*? - any 0 or more characters, as few as possible
\); - a ); substring.
