From: Joseph Brenner <doom <at> kzsu.stanford.edu> To: emacs-pretest-bug <at> gnu.org Subject: 23.1.50; weak documentation of prefer-coding-system Date: Wed, 04 Nov 2009 13:25:09 -0800
The function prefer-coding-system does not explain if the CODING-SYSTEM argument must be a symbol or a string (or either). Without seeing a code example, a user might try using a quoted string: (prefer-coding-system "utf-8") In which case, the error message is very confusing (this makes it sound as though utf-8 is not supported): error: Invalid coding system `utf-8' At a minimum, the documentation should be made more explicit, and I would strongly suggest adding a code example: (prefer-coding-system 'utf-8) In GNU Emacs 23.1.50.1 (x86_64-unknown-linux-gnu, GTK+ Version 2.16.1) of 2009-10-22 on fineline Windowing system distributor `The X.Org Foundation', version 11.0.10600000 configured using `configure '--prefix' '/usr/local/emacs/cvs-102209'' Important settings: value of $LC_ALL: nil value of $LC_COLLATE: nil value of $LC_CTYPE: nil value of $LC_MESSAGES: nil value of $LC_MONETARY: nil value of $LC_NUMERIC: nil value of $LC_TIME: nil value of $LANG: en_US.UTF-8 value of $XMODIFIERS: nil locale-coding-system: utf-8-unix default enable-multibyte-characters: t Major mode: Text Minor modes in effect: shell-dirtrack-mode: t display-time-mode: t tooltip-mode: t mouse-wheel-mode: t file-name-shadow-mode: t global-font-lock-mode: t font-lock-mode: t blink-cursor-mode: t global-auto-composition-mode: t auto-composition-mode: t auto-encryption-mode: t auto-compression-mode: t column-number-mode: t line-number-mode: t transient-mark-mode: t Recent input: <return> g f C-x 1 s C-p C-p C-p C-p <return> SPC SPC <return> C-p C-p o C-n C-n + P i c k <return> C-n R P i r SPC <backspace> c SPC <return> <return> SPC <return> C-p C-p f o <backspace> C-n C-x 2 C-x o M-x s h e l l <return> k 3 b SPC & <return> C-x 0 C-x 2 ^ ^ ^ g C-n f g f g C-n o C-p s C-n C-p C-p C-p C-p C-p C-p C-p C-p C-p o g o C-n C-n C-n C-n C-n o <switch-frame> <switch-frame> <switch-frame> <switch-frame> C-x o g ^ g ^ g C-x 0 g C-x 5 0 C-x C-b C-x o C-n C-n C-n C-n C-n C-n C-n C-n <escape> < C-s n o t e s - C-a f <escape> > C-n C-n C-y C-a C-k C-y C-x C-x C-p C-o C-o D r e w SPC A d m a <backspace> <backspace> a m s SPC n u d g e s SPC m e SPC t o SPC d o SPC a SPC b u f <backspace> g SPC r e p o r t : C-x C-s C-x C-p M-x d o o m SPC r e v SPC <return> C-x o C-x C-g C-a C-n C-x C-o C-x C-s C-n C-l C-n C-n C-n C-n C-k C-n C-k C-k C-k C-x C-o C-x C-s C-n C-n C-n C-n C-n M-f M-b M-h v <return> M-h f <return> C-SPC M-f M-f M-f M-w C-x C-p M-h i u u u <return> s C-y <return> <prior> u u u C-n C-n C-n C-n C-n C-n C-a <return> s <return> s <return> s <return> C-x 0 C-a M-x r e p o r t SPC e m SPC b SPC <return> Recent messages: Searching subfile elisp-2...
