Using ETAGS/CTAGS in emacs with C++ Project

Question

Im using emacs and etags to navigate my way round a project, is it possible to get to a header file easily by searching for a function. I have been using VisualStudio and I can view it by clicking goto declaration is there a similar way using etags in emacs?

e.g.

ArchiveDialog::onKeyPress()

search for the declaration of onkeypress that will be in the header file of ArchiveDialog (#include at the top of the source file).

at the moment when im using etags "M-. onKeyPress" will just find the tags in cpp files and not my header files.

Any help would be appreciated Thanks

Answer 1

Semantic from CEDET should provide corresponding functionality... Please, look onto this section and into "Semantic User's Guide" for more details...

Yes, I believe so.

First you should know, there are 2 versions of etags. There is the one that ships with emacs, and the version of etags that comes with Exuberant Ctags.

http://ctags.sourceforge.net/

You want the second version of etags. That version has more options, including an option to tag function prototypes.

I think this option may work for you, although I have not tested it:

--C++-kinds=+p

Once declarations are tagged, both will show up as results when you try to jump to a tag. If you land on the declaration when you want the definition, or vice versa, type "C-u M-." to go to the next match.

I think GNU Global may also let you jump to declarations, although its been a while since I used it. However, Global's C++ parser has some bugs...

From your description, it sounds like you might have run etags on the source file(s), but didn't specify the #include file(s). Assuming your header (#include) files have '.hh' suffix and are in the same directory as your source, do the following:

cd $project_directory
etags --append *.hh
