Ignore specific different comment pattern (but not the whole line)

[Bainion]

I'm want to compare some instruction files for CNC that don't have the same comment pattern as the default IgnoreComment plugin. In my case comment are between parenthesis.

Could it be possible to add a way to ignore part of lines following a pattern. Maybe that the IgnoreComment can have configurable comment boundaries where we can set start and end of comment symbols.

This could also be useful for some other languages/type of files with different comment pattern.

Adding a Substitution filter that replaces comments with empty strings as shown below may get you the results you expect.

Thanks but unfortunately it doesn't work.
First it only works for lines that are only composed of a comment. If there is code and a comment it doesn't ignore the comment part. Even with the full comment lines it does not work constitantly. Some are ignored but for other it is still considered as a code difference.
There doesn't seem to be any rhyme or reason as to why some lines are recognized or not.

Do you mean it doesn't work if the code and comments are different on both sides of the same line? I think it would work if the code matches but the comments are different. This is a limitation of the current WinMerge functionality. If it doesn't work when the code matches but the comments are different, could you please attach a file that shows the problem?
