Re: ctags/etags: rc file?

Hi,

Yes, ctags has such ability.

       --options=file
            Read additional options from file. The file should contain one
            option per line. As a special case, if --options=NONE is spec‐
            ified as the first option on the command line, it will disable
            the automatic reading of any configuration options from either
            a file or the environment (see FILES).

There is more advanced feature.
Look at my work at fishman/ctags:

     https://github.com/fishman/ctags/blob/master/docs/f-optlib.rst

Optlib may be the feature you want.
fishman/ctags was a branch of exuberant-ctags. However, these days
fishman/ctags people are talking about merging the result into
exuberant-ctags:
