cperl-info-buffer sometimes fails to load correct info page

[VladimirAlexiev]

Steps to reproduce:

1. open info with C-h i. Make sure you're at the directory (press d if needed)
2. Invoke (cperl-info-on-command "shift")
3. Get error search-failed "^-X[ ]"
4. If you look at the open buffers, you'll see:

• *info* (perl) perlfunc but not at the right function, and
• *info-perl* (dir) Top

Somehow the switcheroo in cperl-info-buffer doesn't get it right

[choroba]

I don't understand. Open a Perl program, move your cursor at shift, press C-c C-h p Enter. Same for namespaces (e.g. Path::Tiny).

[VladimirAlexiev]

C-c C-h p invokes cperl-perldoc. This issue is about C-c C-h f or cperl-info-on-command. But thanks for the pointer!

Apologies for a slightly off-topic question, but this is the only place on the internet where I can find a remotely recent reference to info documentation for Perl. @VladimirAlexiev, where do I find up-to-date info documentation for Perl? In fact, the reason I came here was to suggest removing the info-related functions from cperl-mode, because it seemed to me they are obsolete!

@rrthomas I got "Perl 5.6.0 and Module docs snapshot as of 2001/03/15-ish, converted to Emacs TeXinfo and Info format. Krishna Sethuraman [email protected]"

I can't find this distribution. I find two others, I guess they are older

• https://github.com/gitpan/perl-54-info
• https://github.com/gitpan/perl-info: this one has scripts for converting POD to TEXI/INFO

I am a casual perl user, so I don't need the latest info. I appreciate the convenience of having all of this in info.
Seems all these modules are abandoned, so it will be highly appreciated if someone renews perl info efforts.

Great, well if it's still possible to make, then I guess it's up to some Perl & texinfo fan to make a more up-to-date version, but as you say, even older versions can be useful, so I wouldn't suggest removing support from cperl-mode given that.
