Today, I am going to discuss my attempts to parse c style comments.
//This is a comment<br></br>
/***This is also<br></br> *** a comment ***/
Initially, I came up with a regex for /…/ style comments :
Well, the above expression was not able to parse comments like:
<br></br> /*** This is a comment ***/<br></br>``` I googled and came across [http://ostermiller.org/findcomment.html](http://ostermiller.org/findcomment.html) where I found the regex: `<strong>/*(.|[rn])*?*/</strong>` This was able to match comments like the above one. But it’d also match the following /*…*/ comments which are not really comments:
s = “This is a string: /* with a comment /”;
I then worked on a regex for //… style comments:
Then I combined the two regexes by or and my regex pattern becomes:
Now, this pattern is able to search for both: //… and /…/ style comments and avoid matches for patterns like:
<br></br> //comment1 /*<br></br> foo();<br></br> //comment2 */``` One caveat that remains is the /*…*/ pattern in `s = "This is a string: /* with a comment */";` getting matched. If any one has a work around this issue, please comment. I hope this helps.
