Re: Abbrev suggestions - feedback appreciated

[Mathias Dahl]

Actually, my "clever" idea was that you don't read any word at all: just
go though the existing abbreviations, and check for each one of the if
the text before point matches the expansion.

Admittedly, I don't think we currently have a fast implementation of the
equivalent of (looking-back (regexp-quote expansion)), so I don't know
how well it will perform.

My simple function `asug-get-previous-words' function performs quite well,

it seems. I could not get `looking-back' to work across lines. It was very quick

though, when words was on the same line.

Also, collecting all active abbrev expansions was also very fast (1000 runs

takes 0.1 on my not very hot PC) so I did not bother with that optimization. But

perhaps I will experiment a bit with that too.

All in all this seems to turn out quite nicely. I will try to integrate it properly in

abbrev.el and add some option there to toggle this feature on.

Thanks for the pointers!
