Re: [j-devel] Perl mode and extended regexps

[Chris W. <ch...@qw...>]

Hi Peter and all,

I think I've spotted another bug with the Perl mode. Open an empty Perl 
buffer and enter just the following text:

 	if ($i scalar @path - 1 and $perms =~ m|^-|) { }

Now position the cursor at the start of "scalar" (before the "s") and 
press "=". The screen shows:

 	if ($i =~ m|alar @path - 1 and $perms =~ m|^-|) { }

i.e. the text appears to have been subtly corrupted by this innocent 
action! Pressing backspace reverts the text to normal.

Only the "=" and "!" characters have this magical effect. Others work as 
expected.

Pressing "=" a second time reveals that the string "=~ m|" appears to have 
been displayed instead of the buffer contents at those character 
positions. If the file is saved and examined on disk, it contains the 
expected text:

 	if ($i ==scalar @path - 1 and $perms =~ m|^-|) { }

Also, if one copies and pastes the line (pasting outside of J), the 
expected text is pasted. So it would appear to be a bug in the syntax 
highlighting or formatting code, not affecting the underlying buffer 
contents.

Is this the bug that it appears to be, or am I doing something stupid? J 
0.21.1 (thanks!).

Cheers, Chris.
