abbreviation ending with "."

abbreviation ending with "."

[finotti]

Hi,

I want to have an abbreviation that turns "p." into
"para" (Portuguese).  But all my abbreviations that end with "." are
not expanded.  I googled around and could not find anything on this.

Any ideas?

Thanks,

Luis

Abbreviations by default only work if they're exclusively made up of
"word chars" (a.k.a chars of syntax class "word").

So you can either change the char "." to be a word constituent (which
may lead to surprises), or you can change the setting on the
abbrev-table in which you placed that "p." abbreviation.

E.g. if it's added to the abbrev table named `foo-abbrev-table', you
could do

   (abbrev-table-put foo-abbrev-table
                     :regexp "\\<\\(\\w+\\.?\\)\\W*")

See C-h v define-abbrev-table to see the default value used for
the :regexp (to which I just added \\.?).

I see.  Thanks for clarifying that.

Should I put it in my .emacs?  If so, it did not work.  (BTW, I have
it in my global-abbrev-table.)

That command did not work for me: define-<TAB> gives only "define-key-
rebound-commands"...

Any suggestions?

Thanks again for the quick reply!

I should have said C-h f (help for functions) rather than C-h v (help
for variables).

This does not seem to work. I tried the following with emacs -Q 

(progn
   (setq abbrev-mode t)
   (define-abbrev-table 'my-abbrev-table '(
      ("success"         "success again")
      ("try."            "try again")))
   (abbrev-table-put my-abbrev-table
                        :regexp "\\<\\(\\w+\\.?\\)\\W*")
   (setq local-abbrev-table my-abbrev-table))

success expands as success again.
try. does not expand.

Strange enough, If I try to make a new expansion for "try." with C-x a i l, 
it says that I am trying to overwrite the "try. -> try again" expansion, but 
there is still no expansion. What am I doing wrong ?

Here an explizit 'M-x expand-abbrev' does it, but <space> not.
Seems a bug somewhere.

Good catch.  `self-insert-command' only calls `expand-abbrev' on word
ends (i.e. when inserting a non-word char after a word char).
Hmm...
