「How can I make emacs do something similar with if-fi constructs as it
does with parens? 」
To match paren, you want to turn on Show Paren Mode under the Options
menu. Once the mode is on, when your cursor is on a paren, the
matching paren (or the entire enclosed text) will be highlighted, and
you can jump to it by forward-sexp.
For details on these, see:
★ Tips For Editing Lisp Code With Emacs
http://xahlee.org/emacs/emacs_editing_lisp.html
Now, the problem is to make it work for shell's if/fi syntax. Alan
Mackenzie gave suggestions how to properly implement this, but he
drivels on like a militarist sees the world.
Here's a hack that does what you want.
(defun jump-to-if-fi ()
"jump to “fi” if cursor is on word “if”, and vice versa."
(interactive)
(let (myword)
(setq myword (thing-at-point 'word))
(if (equal myword "if")
(progn
(set-mark-command nil)
(search-forward "fi")
)
(if (equal myword "fi")
(progn
(set-mark-command nil)
(search-backward "if")
)
)
)
)
)
(global-set-key (kbd "<f8>") 'jump-to-if-fi)
