bug#4019: command to move point to #else (or #elif) in c-mode

[Dan Nicolaescu]

When looking at code with a lot of preprocessor conditionals, a lot of
times it is very useful when the point is at an #if to move it the
corresponding #else (or #elif) to check what is happening on the other
branch of the #if.  C-c C-p and C-c C-n are not very useful when you
have to deal with a lot of nested and not nested #if #else.

Please consider adding such a command.

Thanks!

This wishlist request was reported in 2009, but never got a reply.

It seems to me that such a command would be useful but is still missing.

There are c-down-conditional-with-else and c-up-conditional-with-else,
which you can bind to a key if you use them frequently.

OK, so I guess this has been fixed meanwhile?  Should the request be
closed?

Yes, I think so.

No.  The two commands have always been there (for values of "always"
greater that 20 years).  Maybe they need more publicity, somehow.

I'm not sure that c-down/up-conditional-with-else are exactly what the
OP is asking for.

Me neither, but this reminds me -- do we have a command/minor mode that
tells you all the C conditionals you're inside?  I'd love a minor mode
that'd say (in the mode line, for instance), that I'm inside

HAVE_UNEXEC -> DOUG_LEA_MALLOC

or whatever.

There wasn't any response in a month, and it seems unlikely that
there'll be more progress here without input from the original bug
reporter, so I'm closing this bug report.

If progress can be made, please respond to the debbugs address and we'll
reopen.
