Emacs TODO List: Have a command suggestion help system that recognizes patterns

Emacs TODO List: Have a command suggestion help system that recognizes patterns

Hi there,

I'm working on a command suggestion minor mode. I just realized that this is
also an item on the Emacs TODO list (C-h C-t), and that I should contact you
about it on off chance that you want it, or have some suggestions about its
implementation. The code is located at http://github.com/tlh/re-suggest.el

From the comments:

;; re-suggest.el is a simple command suggestion minor-mode. It works
;; by mapping commands to characters, creating a string out of the
;; character mappings of recent commands, matching the resulting
;; string against a list of user-defined regexps that correspond to
;; command sequences, and finally suggesting a better way to do things
;; when a match is found. re-suggest looks strictly at sequences of
;; commands, not sequences of keystrokes, avoiding complications
;; resulting from different keybindings in different modes.

So re-suggest actually uses the built-in regexp engine to do its command
pattern matching.

I'm more than willing to sign the papers if you actually want it. I'd love
to hear from you.

I'm not sure why you bother turning the commands into single-letter
chars, rather than just use their full name, but it looks interesting.
I think the most interesting part is the recs-cmd-regexps.

What do people think about this?
We could definitely add it to elpa.gnu.org, but of course, this would
require you signing some copyright paperwork for it.
BTW, please try C-u M-x checkdoc-current-buffer a few times to fix some
minor coding convention details.

This reminds me a peephole optimisation in compilers. Indeed I see
a potential. Looks good. However the messages should be really symbol
names. Also, a good thing for further would be remember missed
combinations, and have access to a summary of missed commands. More
annoying this mode would be - better chances for somebody to get rid of
bad habits.  Making rules programaticaly would be an advantage too,
keeping those in some configuration file.
And I agree, mapping to letters is not needed, and less readable.

Well, the intent with messages being strings was that the user could
define their own warning messages. As it stands, any command name
quoted `like-this' gets extracted, and its keybindings, if they exist,
are displayed along with the suggestion.

I agree on the silliness of mapping commands to characters. I'm
working on converting it over to use full command names.

Logging matched patterns, interactive pattern definition and a
separate config file are all good suggestions. I'll put them on the
TODO list.

recs-mode can be made *really* annoying, if you wish. It can ding and
steal the window selection out from under you. And `recs-hook' is run
for every pattern match, so you can define arbitrary code to run on
match.

Thanks for your input,

I've updated recs.el to match on full command names rather than mapped
chars,
and to return command name symbols per Wojciech's suggestion.
You can view the changes here: http://github.com/tlh/re-suggest.el

Honestly, it didn't cross my mind to just use commands' full names,
probably due to some misplaced concern for efficiency. You're right,
though -- using command names would make it considerably easier to
read and configure. I'll convert it over first thing.

I've corrected most of the warnings thrown by checkdoc-current-buffer,
although "First line is not a complete sentence" is a little difficult
to pull off in 80 chars :) The updated code can still be found at
http://github.com/tlh/re-suggest.el

I should have matching on command names completed by tomorrow or the
next day.

So what's the next step? I'm willing to sign the copyright papers, of
course.
