[MMM] mmm-mode and `awk-mode' as a submode for shell-script

[Alex L. <al...@us...>]

Folks,

I've just started using MMM - great package - great idea!  I have
shell-scripts that have embedded `awk' in them.  I've successfully
created an `embedded-awk' mode, from .emacs:

(require 'mmm-mode)
(mmm-add-find-file-hook)

;;{{{ awk embedded in shell

(mmm-add-classes
 '((embedded-awk
    :submode awk-mode
    :front "awk --source='"
    :back "'")))

;;}}}

MMM correctly identifies and font-locks the regions in the shell
script, for example, in the script below, `awk' mode is in effect from
the left of "awk --source='", to the end quote "'", but the automatic
indentation that is usually in effect in `awk' mode is totally screwed
up.  It left-justifies every line, no matter what the content,
i.e. if-then statements are not indented correctly.  I know that in
the FAQ it mentions that "often this sort of problem can be fixed by
adding elements to `mmm-save-local-variables'".  I'm fully prepared to
look into this, but it would be nice to know what variables may or may
not be relevant to look at, in the context of indentation.

test_fun() {
    awk --source='
BEGIN {}

for (i=0; i<test; i++) {
print "something";
}

$5 ~ /^sfdsdf$/ {
print "echo";
}
$6 ~ /5/ && $3 !~ /4[gh]4/ { 
print "no echo";
}
'
}
# Local variables:
# mmm-classes: embedded-awk
# End:

I'm using the pretest version of GNU Emacs 21 (emacs-21.0.91.1) with
mmm-0.4.6.  I will attempt to duplicate the problem in GNU Emacs 20.7,
to see if this is an incompatibilty problem with Emacs 21, but I
wanted to see if MMM and the bleeding-edge of Emacs would work
together, since I expect that Emacs 21 will be out real soon now...

Thanks,

Alex
