From: Michael Albinus <michael.albinus <at> gmx.de> To: bug-gnu-emacs <at> gnu.org Subject: 26.0.91; info-lookup-symbol oddities Date: Thu, 15 Feb 2018 09:12:28 +0100
The Emacs manual says in section "26.6.1 Info Documentation Lookup": "The major mode determines where to look for documentation for the symbol—which Info files to look in, and which indices to search." This is not really true. No major mode determines itself "where to look for information", this is hard coded in info-look.el. See the several info-lookup-maybe-add-help calls in that file. I do not recommend to change this section for Emacs 26. But shouldn't it be more transparent, how a major mode "determines where to look for documentation"? Something to be said in the Elisp manual? Furthermore, some hard coded locations in info-look.el seem to be deprecated. If I, for example, choose manually autoconf-mode as symbol help mode, I get (taken from the *Messages* buffer): Processing Info node ‘(m4)Macro index’...done Processing Info node ‘(autoconf)Autoconf Macro Index’...done Processing Info node ‘(autoconf)M4 Macro Index’...done Processing Info node ‘(autoconf)Autotest Macro Index’...done Processing Info node ‘(autoconf)Macro Index’...

It doesn't mean that the mode's code specifies that; it means that Emacs determines where to look by consulting some data base that takes the mode into account.

I'm not sure Emacs should only support the latest versions of each manual. Of course, it would be good to see what replaces those nodes in the latest manuals, and then _add_ them, but without removing the old ones. patches welcome. Thanks.
