Subject: 23.1.50; compilation-mode not matching perl and more [regression]
Date: Sat, 25 Jul 2009 22:42:44 +1000

[Message part 1 (text/plain, inline)]

Running "emacs -Q etc/compilation.txt" and scrolling down to the perl
section shows none of the sample perl errors matched at all, where I
hoped they would be.

I think the "^" anchor added by compilation-mode-font-lock-keywords
means perl and some other more obscure patterns need a ".*", like they
had back in Emacs 21, to work in the middle of a line.

I noticed this on the perl one.  I thought it was working fine not so
long ago, so I don't know what/when/how it went bad.  (The looseness of
Emacs 22 not anchoring reverted, but the patterns not put back at the
same time too??)

	* progmodes/compile.el (compilation-error-regexp-alist-alist):
	In aix, ftnchek, mips-1, mips-2, perl, sun, 4bsd entries add ".*" so
	as to match in the middle of a line, now that there's a "^" anchor is
	again enforced by compilation-mode-font-lock-keywords.  These patterns
	were otherwise failing to match anything at all.
	In the 4bsd entry remove the "^" from inside the \\(\\) grouping since
	it's now unnecessary and since inside a group it isn't recognised by
	the omake indentation hack in compilation-mode-font-lock-keywords
	(meaning it wouldn't work with indentation).
