By the current uninstall rule,
the following command is run in the ${infodir}
directory:

$ rm -f cl* ada-mode*
autotype* calc* ccmode* ebrowse* efaq* eintr elisp*
eshell* eudc* idlwave* message* pcl-cvs* reftex*
speedbar* tramp* widget* woman* dired-x* ediff* emacs*
emacs-xtra* flymake* forms* gnus* info* mh-e*
newsticker* org* sc* ses* vip* smtpmail* url* rcirc*
erc*

Now if another package, say the clisp project, happens
to also offer info pages, those pages can be ruined by
this command.

Imagine that Clisp offers clisp.info, installed in
${infodir}. It matches cl*, and is thus removed by
make uninstall.

    erc*

We could make these more specific.  For instance, it could be

cl cl-*

or even

cl cl-[0-9] cl-[0-9][0-9]

for each one of the manuals.

But that is rather clumsy.  Is there any cleaner way to do it?
Perhaps with a shell program that is given an argument such as
`cl', and returns the list of file names for that manual.
Do you know how to write one?

With a for loop; automake uses this to uninstall info
files (from lib/am/texinfos.am in the Automake package
- I only strip the DJGPP stuff):

        @list='$(INFO_DEPS)'; \
        for file in $$list; do \
          relfile=`echo "$$file" | sed 's|^.*/||'`; \
          (if cd "$(DESTDIR)$(infodir)"; then \
             rm -f $$relfile $$relfile-[0-9]
$$relfile-[0-9][0-9]; \
           else :; fi); \
        done

I did not think about all the details yet,
but it should be possible to scan the "Indirect"
section in the main info file, and read the rest of
the info files from there.
The program should be put in the texinfo package under
utils I think. However, maybe that regex is safe
enough.

I forward this to bug-texinfo@gnu.org .

                 rm -f $$relfile $$relfile-[0-9] $$relfile-[0-9][0-9]; \

Isn't that exactly what rms suggested?

It seems better (and way less work) than writing a new program that
parses info files to find out the filenames to me.

yes, only enveloped in a for.

Agreed.

The cleanest way I know of is to have a single list of main Info files
(i.e., without the -[0-9] etc. suffixes, and then do something like
this:

   for f in ${INFO_FILES} do
     rm -f $$f $$f-[1-9] $$f-[1-9][0-9]
   done

We could then have the install target use INFO_FILES as well.

That is indeed clean.  Please install that.

dangerous command in Makefile.in uninstall rule

[Claudio Fontana]

Hello,

as part of the uninstall rule in Makefile.in
(top_srcdir)
the following command is executed:

        (cd ${infodir} && rm -f cl* ada-mode*
autotype* calc* ccmode* ebrowse* efaq* eintr elisp*
eshell* eudc* idlwave* message* pcl-cvs* reftex*
speedbar* tramp* widget* woman* dired-x* ediff* emacs*
emacs-xtra* flymake* forms* gnus* info* mh-e*
newsticker* org* sc* ses* vip* smtpmail* url* rcirc*
erc*)

this is very dangerous, because by this command other
info files, unrelated with emacs, can be removed.
