ETAGS & find-tag

ETAGS & find-tag

[A Soare]

Do you consider normal that M-. <find-tag>

jumps in order to the following definitions (of function or variable) using C-u as prefix :

find-tag-hook
find-tag-default-function

but not to... find-tag?

I opened TAGS file, and <find-tag> was not there.

Still I had created the TAGS by

find -name *.[ch] -o -name *.el | xargs etags -

1. The first problem is in etags.
2. The second "problem": Why M-. <name> does not jump first of all to all defun or defvar which are called EXACTLY <name>, and after there are no more such ones, to jump to the non-exact regexp matching.

No.  It should jump to find-tag first, then to the other ones.  In fact,
I cannot reproduce the behaviour you describe.

Which etags did you use?  I can see the tag whith either new or old
etags.

In this particular case this works, but don't do that in general,
because xargs may make two calls to etags as the consequence of too many
arguments, and in this case you would get a second TAGS overwriting the
first one without any warnings.  For Emacs, just do `make tags'.
