If you use the location to specify where to place the comment, it will only match if its above the comment tag. Otherwise, it seems to match itself, and the output is placed above the comment tag.

Heh; nasty. I can imagine that might happen. Do you have a testcase, please? Use LitterTray web.


Have created a test case here: Item3689Test

Yep. That is confirmed.

I have fixed this for my local install. Maybe you can patch the release. All I have done is modified the regex to skip lines starting with a % sign (i.e. %COMMENT..).

The code is below, starting at line 250 in lib/TWiki/Plugins/CommentPlugin/Comment.pm

            if ( $position eq 'BEFORE' ) {
                $text =~ s/^[^\%]($location)/$output$1/m;
            } else { # AFTER
                $text =~ s/^[^\%]($location)/$1$output/m;

Obviously, if people decide to use the start of line in location, then this will break it. But its a quick fix anyway.

It would be an easy check to see if location=" is not just before the match.

Also fixed a warning in locations, highlighted while unit testing.
