In a previous article I described how to create a parser for a pseudo-INI file. The grammar presented in the post is unfortunately unable to parse inline comments correctly.

I asked for ways to improve it, both on perlmonks and on IRC. After some testing it turns out that a slight change is enough: the first line of the grammar should be changed to:

AsIni: <skip: qr{s*(;[^n]*ns*)?}s> Line(s?) /Z/

Unfortunately, this won't print the skipped content (as CommentLine) does. From the answers I had it's not quite clear if this is actually possible with Parse::RecDescent. Anyway, I am satisfied with the result so far 🙂
