Yes you can: you need the latest version of Apache::DB. For now, you
have to run httpd -X to prevent it from forking, but I'm working on
that limitation.
You have to run a wrapper script around Apache, because Emacs insists
on fiddling with command line switches assuming that the real
/usr/bin/perl is used as the interpreter (which it won't). That
wrapper should run apache -X, after setting the following environment
variables:
~ * PERLDB_OPTS="TTY=$tty ReadLine=0 ornaments=0" where $tty is the
~ tty the wrapper script is attached to (obtained e.g. with
~ `/usr/bin/tty`)
~ * MOD_PERL_TRACE="dshg" (only relevant if mod_perl was compiled
~ with debugging on)
Here are appropriate httpd.conf snippets to honor this setup:
PerlPassEnv PERLDB_OPTS
PerlPassEnv MOD_PERL_TRACE
PerlPassEnv TERM
<Perl>
~ BEGIN { if ($ENV{PERLDB_OPTS}) {
~ require Apache::DB;
~ Apache::DB->init;
~ require 'Apache/perl5db.pl';
~ warn "Support for editor embedding (e.g. Emacs) enabled\n\n";
~ $DB::slave_editor=1;
~ }}
~ $DB::single = 1;
# Your usual <Perl> stuff goes here
</Perl>
Now launch Emacs, type M-x perldb <ret>, erase the minibuffer
contents, type in the path of your wrapper script followed by a bogus
command-line argument (e.g. "/home/dom/bin/apache-gud mod_perl"). The
debugger should stop at the "$DB::single = 1" line above.
