External tool for building cross-reference table from cscope/ctags (was Re: call graph functionality)

[hari.ra...@gmail.com]

After the discussion in this thread, I spawned off a new project: ccglue. ccglue is a native application that can build cross-reference tables from cscope (and ctags, in future versions). The generated cross-reference can be traced directly from disk by the CCTree plugin  without any additional load time.

ccglue is available in posix/win32 flavors and cross-reference building times are in the order of tens of seconds even for extremely large cscope database sizes.  ccglue can be run in the background or as a shell command similar to updating ctags and cscope database. ccglue should make it more practical to use large-sized projects with CCTree.

hi hari,

i really appreciate your effort on this front.
i guess the only reason the script is not
being used by many hardcore programmers
is it's lack of usability for huge projects.
as it is obvious that you are clearly working
on it to make it better. i would love to give
it a try, but the only reasonable way for it
to become useful is when it gets the capability
to run in background.

cheers
