emacs + etags

[rkv]

hi all,

I having large project , divided in to number of opensources and libraries
each having a TAG file.

If i change from one directory to another one , and search for any specific
tag in the file related to the current directory

i get message as No Tags Containing <the speficic tag>

I would like to know how to make the change of the current using TAG file.

regards
rama kanth

You should set tags-file-name variable.
Alternatively, I think you can also use tags-table-list - a list of
all tags files -  but I have never tried... I suppose it will search
in all tags files.

It may be of little use to you, but XEmacs provides a tags mechanism
which achieves what you describe.

Try out my `ctags.el'[1] module.

Configuration example:

  (setq tags-revert-without-query t)
  (global-set-key (kbd "<f5>") 'ctags-create-or-update-tags-table)

Then just press <f5> to update or create your TAGS file. That function
look for a file TAGS in the current and its parent directories, if a TAG
file is not found it ask you where create a new one.

It is a new library and probably has bugs, etc, so any help is welcome.

Changing to XEmacs for a feature seems a little extreme. Especially with
the somewhat ropey spec above.

The EMacs Wiki lists ways of changing the tags files  used based on the
project directory of the opened file.

etags-table I think.

I am not exactly sure what you are looking for, but note that Emacs 
allows you to have several tags files loaded and to select some subset 
of them for active use at any given time.  The info manual has all the 
details.
