Autocomplete for Objective-C

Autocomplete for Objective-C

[Germán Arias]

Hi,

Is there available autocomplete for Objective-C, using GCC? If not, is there an example about how do this? I know that etags allows you create tables. But not sure how this works.

Regards.
Germán.

Germán,

You might consider looking at CEDET/EDE/Semantic. I'm hardly an expert, but it has some very good tools for different languages.

WRT tags: Tags let you jump to a symbol's definition (and back again). It's very useful, but doesn't address your explicit question. To use etags with Objective C, I would go to the root of your source tree and type:
    $ etags $(find . -type f -name '*.m')
M-. will ask you for a tag (or use the symbol at point if you want). The first time you use it, it will ask you for a TAGS table. Just give it the root directory of your source tree.

Of course, shells have one feature that no other language has: subshells.

CEDET does not support Obj-C.

Yes, I noticed this today. But, can I use a table to do basic completion? Or I need write some semantic rules?

If you use tags, then M-/ (dabbrev-expand) may just do what you want without anything new.

I don't know if the etags that is delivered with emacs supports Objective C, but Exuberant Ctags (http://ctags.sourceforge.net/) is very flexible. While it does not claim to support Objective C, it can be extended for new languages via regular expressions. I use something like the following to get support for a somewhat obscure language called Passport:

etags --langdef=pl --regex-pl="/procedure[[:blank:]]+([_[:alnum:]]+)/\1/" --language-force=pl

Thanks, took me some time understand the syntax of regex. But I achieved it, now I need refine my regexp.

If you don't mind using Clang for completion, you can try Company:

http://company-mode.github.io/

The bundled company-clang backend supports Objective-C.
