Emacs as C IDE

Emacs as C IDE

[Lorenzo Isella]

Dear All,
I am working on a fairly large (for my standards) C project. I have to
browse different .c and .h files and sometimes I feel lost. It would
be wonderful, when looking at a single file, being able to "visualize"
(maybe in a different window) its skeleton: structures, functions
etc... or to collapse them in the view of the original file.
I have not found what I am looking for, but I cannot believe that
nobody has ever taken steps in this direction.
I should add I am using cc-mode right now,
Many thanks

Lorenzo

There is a project called ECB. Maybe that's what you want. But I never
used it, so can't give other advice.

http://ecb.sourceforge.net/

Yep, that's the one you should have a look at. It makes use of CEDET:

     http://cedet.sourceforge.net/

("a collection of tools written with the end goal of creating an advanced
development environment in Emacs")

For finding your way through the code, I still use Cscope under Emacs:

    http://cscope.sourceforge.net/

Alternatively, GNU Global is quite useful and has an Emacs front end, too.

Possibilities I use:

- selective-display can collapse code by level

- speedbar allows file and function browsing in a separate frame

- imenu allows jumping to a function using a GUI menu

(Since it's emacs, there are probably 10 more.)

As well as tags and cscope you should look at xref. Far and away better
than anything else out there I think for code navigation with emacs. 

http://www.xref.sk/xrefactory/main.html

The C version is free now.

In addition there is ecb and semantic - it can get confusing as to what
is what as there are so many options! Unfortunately I think you might be
a little disappointed as the features do not compare to things like
Visual Studio and Eclipse in my opinion.
