I hope this isn't one of those things that is just plain obvious to
lookup in emacs but I'm striking out with M-x apropos

How can I make emacs do something similar with if-fi constructs as it
does with parens?

Even better I'd like the kind of behaviour one can get in vim with
parens, where not only does the syntax coloring show the other paren
but you can jump there with a Ctrl-%

I know emacs can do that as well but not as easily.  But anyway, I use
emacs more and would like to turn its powers used in paren recognition
against the `if fi', `while done', `for done'... etc. one uses in
shell scripting.

Maybe you mean %, not C-%?

You can in Emacs too, using Viper. But see

Thanks for those ... I knew some it but found some more.
But no, I don't want to try to turn emacs into vi so much as turn
emacs power loose on if-fi while-done etc constructs.

That was my my main question and I didn't notice anything on those
sites about that... I hope I just missed it.

So still wondering how to get paren type actions to work on if-fi type
shell constructs.

While you are in a script shell you have keybindings for case, if, 
while getopts, etc... to construct all this statements.
If you do C-h m you will find them.

Maybe they are buried in there somewhere ... I don't see them.
Unless you are talking about the commands that insert a framework for
case while etc.

Or maybe you are referring to M-e M-a which don't really do what I
asked about not even close really.

I'm not asking about how to insert an if-fi statement... I'm asking
how to put the cursor on the `fi' part and jump to the `if' part.  Or
on the `for' and jump to the `done'.

Or at least behave like emacs does with parens.  Place cursor just
after `fi' and the `if' is  highlighted

This is a moderately difficult exercise in Elisp programming.  I would
suggest something like this:

(i) On the i of if, the i of fi, the w of when, the e of done etc., put
"syntax-table" text properties of open-parenthesis and
close-parenthesis.  See pages "Syntax Table Internals", "Text
Properties" and "Special Properties" in the Emacs Lisp manual.

(ii) The best way to apply these text properties might be using
abbreviations - make "if" an abbreviation for "if" together with
applying the property.  You'll need to check that the "if" isn't inside
a comment or string, and this sort of thing.  See page "Abbrevs" and its
sub-pages, particularly the HOOK facility in page "Defining Abbrevs".
Then again, maybe just using (iii) (below) might be better.

(iii) You'll need some way of removing the properties when they
should'nt be there any more - for example, when you comment out a line,
or when you type the "n" of "find".  You'll need an after-change
function here (page "Change Hooks" in the manual) which analyses the
text you're changing.  Beware that font-locking sometimes uses
text-properties, and you might need to synchronise with it.  Be aware
also that some people (including one Emacs core developer) disable font
locking because it annoys them.

When you've got it working, please submit it to Emacs for inclusion in
Emacs 23!  Best of luck!

Yes that would be very nice but is also very unlikely.  My skill level
would have to be improved several hundred percentage points in a
pretty short while.

I guess not too many emacs developers really do much shell scripting.
Probably using a lot more high level scripting languages (perl, lisp,
python and etc).  I run into portability problems more with shell
scripts since something like perl is the same everywhere.

My perl is coming along well enough to use it for all scripting but I
still have many older shell scripts I'd hate to have to convert.

On a slightly different subject... if I may torture the threading
rules a little:
  Speaking of portability... I'd like to get my emacs init files to be
  more portable from one machine to the next but one I'm dealing with
  now has different keyboard responses than most of the others and
  requires differnt keybindings for delete-backward-char and a few
  other things.

  I'd like to include those in .emacs but don't know how to separate
  them off by making them depend on which host emacs is running on.

  Can you give me a push in that direction?

  How to access the env variable HOSTNAME or slurp the results of the
  hostname shell command and make the keybindings dependant on the
  results. 

  I've seen examples of something similar where the code tests if its 
  fsf emacs or Xemacs as a condition.

Don't underestimate yourself.  After all, you've mastered shell script.

Indeed.  Where's the problem with that?  The Emacs documentation
(including that for Emac Lisp) is sensationally good, and there's as much
help as you need on the net.  For functionality this useful, I'd happily
help you by personal email, even several times a week.

This is an ideal problem for getting into heavy elisping - it goes to the
core of Emacs, with hooks, text-properties/overlays, textual analysis
with regular expressions - yet it is tightly enough defined that you
won't just drift into an endless maze of discouraging vagueness and
complexity.  After implementing this, you would be welcomed with open
arms by the core Emacs team.

So, how long would all this take?  Several weeks, assuming ~15-30 hours
hacking time per week.

I would think most Emacsers write shell scripts reasonably fluently.
Lisp isn't really suited for the job, and p{erl,ython} seem over
complicated.  In my humble opinion, of course.  ;-)

So, why convert them?

time

And as you noted.. elisp isn't well suited for scripting so I'm
working on perl.

I'm sure they are fluent.  Way more than I am.

What I said was I doubt they use shell languages as much as someone
who isn't fluent in perl or python.  What I was getting at is there
may not be much of a perceived need for things that aid shell
scripting.  All the higher level stuff uses parens rather than if-fi.

I do agree though that hacking out something to make emacs able to
recognize shell constructs like it does with parens would be a great
learning tool and of some value to the emacs community.  God knows I
owe the community a huge debt for all the help over the years.

I may have to dig into it this new year.

Sorry I missed it in that first link you provided but
Turns out to be right in the emacs FAQ.   I repost it here incase
people searching these forms should hit this thread.

I didn't really like the idea of turning on a whole vi like mode and I
guess a good number of others didn't either.

From the emacs FAQ

   * Here is some Emacs Lisp that will make the <%> key show the
     matching parenthesis, like in `vi'.  In addition, if the cursor
     isn't over a parenthesis, it simply inserts a % like normal.

          ;; By an unknown contributor

          (global-set-key "%" 'match-paren)

          (defun match-paren (arg)
            "Go to the matching paren if on a paren; otherwise insert %."
            (interactive "p")
            (cond ((looking-at "\\s\(") (forward-list 1) (backward-char 1))
                  ((looking-at "\\s\)") (forward-char 1) (backward-list 1))
                  (t (self-insert-command (or arg 1)))))

Have a look at the "Key Bindings" in the Emacs FAQ.

There are several variables you can test to find out what system you're
running under: system-type, system-name, ....   Have a look at page
"System Interface" in the Elisp manual.

    (progn

I think you mean "GNU Emacs".  ;-)  ["fsf emacs" is regarded as rude by
the Emacs project, for reasons I don't fully understand.]

(cond
  ;; linux
  ((string-equal "gnu/linux" system-type)
    (load-file "/usr/share/emacs/site-lisp/site-gentoo.el"))

  ;; darwin
  ((string-equal "darwin" system-type)
    (load-file (concat my-emacs-dir "darwin.el")))
  )

the cond form is a bit easier to extend as the platform list grows.

Sorry for tardy response but looking back over this thread I wanted to
thank all participants for what is a very nice discussion with many
details and suggestions.  Its going into my keeper file for sure.

Sadly, there is not general answer.  Some modes provide special bindings
to do that.  Others extend C-M-f and C-M-b to take those things
into account.
But most don't bother at all. :-(

In case I am not too late, I suggest looking at  gap-mode.el.  It was made
for the GAP computer algebra system, which uses a language with this kind of
syntax.
It does a good job of matching and indentation.  It does not do exactly what
you want, but since the adequate matching functions are there, you can
probably
get some strong leverage.
