Match dashes/underscores in identifiers

[blueyed]

I changed IDENTIFIER_REGEX to include dashes and underscores (in https://github.com/Valloric/YouCompleteMe/blob/master/cpp/ycm/IdentifierUtils.cpp#L37):

const char *IDENTIFIER_REGEX = "[_a-zA-Z][\\w_-]*";

(It would be great, if it could respect Vim's iskeyword setting.)

But that appears to need further adjustments somewhere else.. after completing "foo-bar-baz" it still offers "foo-bar-baz" and completes it to "foo-foo-bar-baz".

See also issue #98 (about comments).

Duplicate issue #86.

Can you tell me, if what I've tried should basically work?
Is there a reason why completion of the matched/collected foo-bar indentifiers behaves strange ("foo-" => "foo-bar" => "foo-foo-bar")?

@blueyed You need to update python/ycm_utils.py like so:

def IsIdentifierChar( char ):
  return char.isalnum() or char in ['_', '-']

That should help.

Thanks, @noprompt - that appears to work.

This works for me too, thanks guys.

For anyone finding this now, this Gist will patch YouCompleteMe to support -'s and _'s as identifiers.
