This happened because, on DOS and Windows, file-coding-system-alist includes the association `("" . find-buffer-file-type-coding-system)', and find-buffer-file-type-coding-system was not ready to see an argument whose `car' does not appear to exist because jka-compr removed the .gz extension from its name.

Actually, this explains why _visiting_ compressed files might produce a buffer with ^M characters in it. The change I made cannot help with Info files because the buffer name is "*info*" in that case, not FOO.gz. After the change, visiting, e.g., emacs-1.gz produces a buffer whose buffer-file-coding-system is -dos, and there are no ^M characters in it. Visiting ccmode-1.gz still produces ^M's (because ccmode-1 includes null characters in the Index node). > > 2.- Additionally, for info nodes that do NOT contain a Top node: > > > > cd info > > emacs -Q --eval "(progn (set-language-environment \"UTF-8\") (info > > \"(ccmode)\")" > > ;; works OK. > > > > gzip ccmode* > > emacs -Q --eval "(progn (set-language-environment \"UTF-8\") (info > > \"(ccmode)\")" > > ;; "No such node or anchor: Top" > > This is yet another separate bug: set-language-environment always sets > default-buffer-file-coding-system to *-unix. See my other message a > few minutes ago. Specifically, I propose the change below for this latter problem. After that change, visiting compressed files, both regular and Info files, work correctly for me, both before or after setting a non-default language environment.

Right, I had that in mind, too. The problem is, it's not trivial. The way it works on startup now is a bit kludgey: dos-w32.el says (setq-default buffer-file-coding-system 'undecided-dos) and then set-language-environment-coding-systems does (let* ((priority (get-language-info language-name 'coding-priority)) (default-coding (car priority)) (eol-type (coding-system-eol-type default-buffer-file-coding-system))) ... (if (memq eol-type '(0 1 2 unix dos mac)) (coding-system-change-eol-conversion default-coding eol-type))) the kludge being that this only works because of the specific order files are loaded at dump time and the order of function invocation during startup. Are we okay with making non-trivial changes in that at this time? ^ permalink raw reply [flat|nested] 9+ messages in thread
