Subject: bug#26564: Document that only functions and not variables can end with "-p"
Date: Wed, 19 Apr 2017 15:47:06 +0000 [thread overview]
Message-ID: <CAFyQvY2Jhe7d7tFMgqQH+oHOHhx2_OXT3UBDYqjbUaXLw-KrNg@mail.gmail.com> (raw)

The discussion on whether variables should end in "-p" came up few time on
emacs-devel, at least the ones I was part of:
1. https://lists.gnu.org/archive/html/emacs-devel/2016-07/msg00734.html
2. http://lists.gnu.org/archive/html/emacs-devel/2017-04/msg00540.html
Doing a rudimentary search in emacs/lisp/ code-base shows a sign of an
undocumented convention that predicate functions, functions that return
either nil or non-nil can end in "-p" (if the function name is multi-word,
like nested-alist-p), or just "p" (if the function name is a single word,
like stringp).
I ran ag[1] in emacs/lisp:
1. 1511 matches -- defuns and defsubsts ending in -p -- ag
'def(un|subst)\s+[^ ]+-p\s+' --stats
2. 149 matches -- defvars, defconsts and defcustoms ending in -p -- ag
'def(var|const|custom)\s+[^ ]+-p\s+' --stats
3. 65 matches -- Just the user-facing defcustoms -- ag 'defcustom\s+[^
]+-p\s+' --stats
That corroborates that more functions tend to end in "-p" than variables.
This bug report is to make a request to incorporate this unspoken rule as a
rule in the Elisp manual.
What would be the correct section to do so?
