26;;; Commentary:
27
28;; This package provides the tools meant to help editing PO files,
29;; as documented in the GNU gettext user's manual. See this manual
30;; for user documentation, which is not repeated here.
31
32;; To install, merely put this file somewhere GNU Emacs will find it,
33;; then add the following lines to your .emacs file:
34;;
35;; (autoload 'po-mode "po-mode"
36;; "Major mode for translators to edit PO files" t)
37;; (setq auto-mode-alist (cons '("\\.po\\'\\|\\.po\\." . po-mode)
38;; auto-mode-alist))
39;;
40;; To use the right coding system automatically under Emacs 20 or newer,
41;; also add:
42;;
43;; (autoload 'po-find-file-coding-system "po-compat")
44;; (modify-coding-system-alist 'file "\\.po\\'\\|\\.po\\."
45;; 'po-find-file-coding-system)
46;;
47;; You may also adjust some variables, below, by defining them in your
48;; '.emacs' file, either directly or through command 'M-x customize'.

50;; TODO:
51;; Plural form editing:
52;; - When in edit mode, currently it highlights (in green) the msgid;
53;; it should also highlight the msgid_plural string, I would say, since
54;; the translator has to look at both.
55;; - After the translator finished the translation of msgstr[0], it would
56;; be nice if the cursor would automatically move to the beginning of the
57;; msgstr[1] line, so that the translator just needs to press RET to edit
58;; that.
59;; - If msgstr[1] is empty but msgstr[0] is not, it would be ergonomic if the
60;; contents of msgstr[0] would be copied. (Not sure if this should happen
61;; at the end of the editing msgstr[0] or at the beginning of the editing
62;; of msgstr[1].) Reason: These two strings are usually very similar.
