Hi All,

This note is mostly a carry over from a note on the ecb list.

What I do mostly is fix code in a large code base.  We have cscope  
db's set up but, if semantic can get me close to what I need, I could  
make local copies of things and create db's myself.

The key is to be able to find all the places in the code base where a  
particular variable (global) or function is used.  cscope gives me  
this.  I don't see how semantic with distributed files could do this.  
So, that is my first question.  Is this something that semantic can  
do or is going to be able to do.

Even in the OO world, you still need to find where, in a hugh code  
base, where things are created.  Where are methods used.  etc.

And, even in a small code base working on my Ruby on Rails projects,  
I need at least TAGS ability so I can go from a method invocation to  
where it is defined.  Can semantic do this?

If it can (or if you plan to make it do that), then I'm really  
interested.

If it can not, then I'm lost.  I don't see, more than making my  
buffer's pretty, what semantic can do.

Thank you for your time,
Perry

Semantic(which is part of Cedet) is really a kind of unified api on top of many possible tag generators. The on-the-fly(wisent) ones are really just one kind. Cedet doesnt support all kinds of tag generators yet, but it does support ebrowse, which is able to handle large codebases. Semantic could be extended to handle etags and cscope as well, and the ebrowse semantic interface could be used as example. "man csope" seems to indicate that cscope support could be added with not too much effort, at least if "compression" is disabled on db creation. Cedet provide jump to definition functionality and lots of interesting stuff. It even supports a combination of on-the-fly parsers, and database parsers, meaning that if an ebrowse db, for example, is not up to date, an on the fly parse can be made and used instead. > Hi All, > > This note is mostly a carry over from a note on the ecb list. > > What I do mostly is fix code in a large code base.

Re: [CEDET-devel] Questions From: Eric M. Ludlam <eric@si...> - 2007-08-23 15:13 Hi, Semantic CAN replace `find-tag', and jump to a definition from code. Using a new command, `semantic-ia-fast-jump', which I happen to have written just recently, it will also find the right owning class if multiple classes define the same method. Semantic CANNOT find all usages of a particular method. Indexing a large project is not really a job for an Emacs Lisp program. Semantic is already pushing the boundary of what is rational in Emacs Lisp. cscope or xref is the right choice here. In your case, the best solution would be if Semantic supported cscope as a back-end as Joakim suggested. That way you could continue to use cscope for some things, and semantic for others. When I investigated cscope, it was missing a lot of detail that Semantic uses to get smart completion stuff working, so I wasn't too motivated to continue, as a TAGS back end would be similar. Beyond the above features, Semantic can also provide smart completion, where it can suggest completions based on the context. Getting this to be reliable and fast is high on my priority list, but it is still a bit slow. I made some checkins just yesterday to fix one accuracy bug in this area.
