This is somewhat similar to the question in https://unix.stackexchange.com/questions/33131/how-to-grep-on-source-code-without-catching-comments - however, what I actually want, is this: provided a C source file like this, myfile.c:
/*
* foo has changed [...] and is now a 2-parameters function
*/
// foo(24)
int myvar = foo(42, 28);
... and grepping/searching for some string (e.g. "foo") in it - the results should contain both:
- the search term colored in one color - and
- the rest of the line colored either with the default terminal text color, or colored differently if it is a comment
So for a pseudocode like:
$ commentgrep 'foo' --match-color="red" --c-comment-color="green" myfile.c
... I would like results like these:
This probably implies that such a tool, like this imagined "commentgrep", should do one pass to look for matches in the file, and if found, do another pass to find and color the comments ...
(and of course, it would be great, if you could also switch language comment styles, so you might have --python-comment-color as well)
Is there such a command line tool available?
