Searching strategy and underscore

[pi2...@piprime.fr]

Hi,

I've the following problem within php-mode.
str<TAB> recognizes str_getcsv as snippet key but
str_<TAB> does not recognize anything.
str_get<TAB> recognizes only words begining with "get".

Reading http://tinyurl.com/yjz4ay7 it seems that it isn't the default
behavior...

Maybe I misunderstood... Thanks to confirm it.

C-h v yas/version<ret>
yas/version is a variable defined in `yasnippet.el'.
Its value is "0.6.1b"

M-x emacs-version<ret>
GNU Emacs 23.1.50.1 (i486-pc-linux-gnu, GTK+ Version 2.18.3) of \
2009-11-28 on elegiac, modified by Debian

Hi! pluskid is the specialist in this stuff, but I'll try to explain
the two distinct cases:

> str<TAB> recognizes str_getcsv as snippet key but
> str_<TAB> does not recognize anything.

I think you're mixing it up... "str<TAB>" will try to find snippets
for the "str" snippet *key*. Another thing is to say that you have the
"str_getcsv" snippet associated with the "str" key.

"str_" will work as a snippet *key* if you have some snippet keyed to
"str_", but it *won't* magically autocomplete to "str_getcsv".

YASnippet is a templating engine, not a completion engine. A very
nice, simple and language-agnostic completion system is bundled with
emacs and is called "hippie-expand". Try 'M-x hippie-expand'.

> str_get<TAB> recognizes only words begining with "get".

`yas/key-syntaxes' has many elements, right? Well, turns out the "word
chars" element of 'yas/key-syntaxes' has precedence over the "word and
punctuation chars" element. "_" being a punctuation char (non-word),
yasnippet won't search further since it already found valid,
expandible snippets for the snipept key "get".

"str_getcsv" snippet is associated with the "str_getcsv" NAME (so it
must be associated with the "str_getcsv" key)

> "str_" will work as a snippet *key* if you have some snippet keyed

My problem is�ｿｽ:
why str is autocomplete by Yasnippet to str_getcsv but str_ not.

Yasnippet is an completion engine... for its own templates.

>> str_get<TAB> recognizes only words begining with "get".

It's a pity�ｿｽ!
Autocomplete str to str_getcsv but not str_ is disconcerting.

yasnippet can be whatever you want it to be because it is free
software. Feel free to fork from it and modify it!

However, the behavior you describe was never a part of yasnippet, not
in its original design by pluskid or ever.

Thanks, I'll think about it.

Ok, you're right again. This feature is provided by the package
auto-complete-yasnippet <http://www.emacswiki.org/emacs/AutoComplete>

Thank for your help, I will not bother most.
