I have some patches to etags (not etags.el) to do this.
The idea is to have a ".etags" config file that tells etags what to do.
Then "etags --find" will read this file, walk the directory tree, and
update the TAGS file.
Here's a sample config file based on what gdb's "make TAGS" currently
does:
# Ignore some test suite files.
!testsuite/*.[chylmsS]
# Ignore some other things.
!*.def
!*/Makefile*
# Handle DejaGNU (Tcl) files using regexps.
*.exp --language=none
--regex='/\(gdb_caching_proc\|proc\|proc_with_prefix\)[ \t]+\([^ \t]+\)/\2/'
Making etags.el auto-update with this is simple: just run "etags --find".
It would also be easy to script this using inotify-tools.
This work still has some minor things to clean up. I didn't make
--include work (I think --find should stop at any subdirectory .etags it
finds, and then process those directories separately -- that is, include
should be automatically handled); and there's some argument validation
to be implemented.
If this sounds interesting, I can clean it up and send it.
