Hi
I'd love to have TextMate like snippets.
I started something similar in my own yi.hs config
file, but didn't continue it due to lack of time :(
In my config i overloaded the Tab-key to do
auto completion, insert tabs or if symbol before pointer
is a snippet keyword expand its snippet. My snippets
even allow to set markers which one can jump to later.
When jumping to a marker - depending on ones
configuration - the marker will be deleted or put to the
end of the list of (buffer specific) know snippet markers.
Writing snippets is fairly simple too using
the '&'-Operator.
e.g. my test case i was playing with:
>
> testSnippet :: SnippetCmd ()
> testSnippet =
> "if ( " & (cursorWith 1 "...") & " ) {\n" &
> "\t" & (cursorWith 2 "/* code */") &
> "\n}\n" & (cursor 3)
This will insert the Text
if ( ... ) {
/* code */
}
and 3 markers. Depending on your config Tabs
will be expanded + the expansion is kinda indent
aware. Meaning indentation of following snippet lines
depends on column the snippet was triggered on.
the text associated with the markers is deleted
when jumping to a marker (currently in my
keymap Ctrl-S), but it would be fine just to highlight
it and delete it only if buffer gets modified whereas
if user chooses to jump to next marker the associated text
is not modified. I planed to use the post-modified-buffer
hook to do this and to add dependent regions
(positions with same cursor id in snippet)...
So, if you are interested you can reuse some of my code.
Unfortunately i have no time to hack on this right now,
but still some discussions will be fine :)

I'm Sorry the code is kinda dirty. But i used this file to play
a little with yi and haven't had time to clean it up. You will
find the main snippets-functionality at about line 280.
cheers
