help needed setting up etags on Windows

help needed setting up etags on Windows

[C K Kashyap]

Hi folks,

Could someone please help me get started with setting up etags for a large
C++ source base? I'd like to use emacs on cygwin. I assume etags is the
right tool for source indexing with emacs.

Regards,
Kashyap

I don't think there's anything to do. 

`cd' to your source directory and run `etags file1.c file2.c ...' and you'll have a tags file. Type `M-x .' with the cursor on the symbol of interest, tell emacs that you want to use TAGS as the tags file and it should find the symbol.

For starters, I cant seem to find a way to install etags in my cygwin
setup..

Looks like etags is part of the ctags package on cygwin...

For C++, you will be better off with ebrowse, a program that also
comes with Emacs.  It understands C++ much better than etags does, and
provides similar commands (so you don't lose anything).  Check out the
Ebrowse manual, which is part of the Emacs distribution, for details.

I guess cscope would be better, and there is an elisp script called xcscope.el.
http://cscope.sourceforge.net/
http://inst.eecs.berkeley.edu/~cs186/fa05/debugging/xcscope.el

But it sucks when you need to modify some of your source code since the
update of cscope database always takes much time(AFAIK, there is no
incremental update at all); so it would be rather annoying if the code
base is large and there is a need to update the tag database
frequently.
There is another tagging system called GNU Global, however
it seems not available in cygwin.

I am going to give cscope (infact, I forgot, I always used cscope with vim
:) )
I'll readup on ebrowse as well ....

Thank you very much,

RE: help needed setting up etags on Windows

[Ludwig, Mark]

I hope you will share your results/decision at some point.

I've used etags for decades but have been doing only C coding.  
I'm on the cusp of switching to a C++ project, and etags just doesn't cut it.  
I'll be interested in what you find with Ebrowse.  
I've also seen chatter about CEDET being good for C++.

Cheers,
Mark Ludwig

Here are my related configuration links for C/C++ development:
1. https://github.com/HongxuChen/dotfiles/blob/master/_emacs.d/config/init-cc-mode.el
General cc mode settings
2. https://github.com/HongxuChen/dotfiles/blob/master/_emacs.d/config/init-flymake.el
Add a flymake clang for single files
3. auto-complete-clang+yasnippet+autopair for editing assistance
4. fic-mode for highlight FIXME/TODO etc.
5. source code navigation:
(1) tag based: xgtags.el and xcscope.el(for header files that I never
modify since I cscope seems more accurate than xgtags).
(2) semantic based: cc-lookup(a simple script I write, based on
clang-lookup; it only looks for declaration/definition, no reference
support, no name refactoring support, and more improvements are
expected)
https://github.com/HongxuChen/cc-lookup
6. I also use directory local variables quite a lot

There are also several clang based tools for C/C++ coding:
1. https://github.com/Sarcasm/irony-mode
auto complete headers and code, syntax check; I cannot make the trigger
key right and there are some bugs for its plugins.
2. https://github.com/Golevka/emacs-clang-complete-async
a client-server version of auto-complete-completion; faster than
auto-complete-clang but many bugs
3. https://github.com/Andersbakken/rtags
Powerful tag system, there is a series video about it on Youtube, lookup
defintion/declaration/reference, rename refactoring, code completion;
but I don't know how to configure right:-(
4. company-mode
It's inferior to auto-complete and I don't use it.

Personally I don't like CEDET(together with ECB) since it's too Emacsy
and I come from Vim; the most important thing is that it sucks quite
often and the speed is not satisfying. But there seems a clang semantics
analysis on it and I hope it would make a hit.

cscope seems to run pretty well - http://linux.die.net/man/1/xcscope is
useful to get started.

I can't speak specifically to cygwin, but this is what I do under gnu/
linux, and I don't see any reason it would fail under cygwin.  I'm happy 
with the results with the exception that I can only do a single source 
tree (so far).  I find the results better for C++ than etags.

1.  From the cygwin installer, install gnu-global or gtags (I don't know 
the name in cygwin).  Alternatively install from tarball.

2.  In the root of your source tree, run gtags.  This will create three 
files containing tagging information.

3.  Install ggtags using emacs package manager.

4.  alt-x ggtags-mode will start ggtags mode.  From there alt-. will jump 
to a given tag.  See ggtags docs for further usage.


Hope that helps.
