Subject: 23.2; ld-script-mode grabs .xs, and probably shouldn't
Date: Sun, 19 Sep 2010 18:35:51 +0100

I just found the following in auto-mode-alist:

 ("\\.x[bdsru]?[cn]?\\'" . ld-script-mode)

which explains why when I open a .xs file, it ends up in ld-script-mode.
I had never even heard of ld scripts. I’m no Perl programmer, but I had
heard of Perl .xs files (which for the uninitiated are basically C, but
with special annotations for writing bindings to Perl).

I suggest that .xs should be awarded to perl-mode.

Subject: Correction: I meant c-mode, not perl-mode

From what I wrote, it should be obvious that I meant that .xs should
be awarded to c-mode, not, as I stupidly said, perl-mode.
