From: Michael Welsh Duggan <mwd <at> cert.org> To: bug-gnu-emacs <at> gnu.org Subject: 24.0.50; c-mode syntax problems Date: Tue, 20 Sep 2011 11:25:08 -0400I really wish I could give an exact recipe for this, but this particular failure is extremely transient. I can leave an emacs open in an bad state for postmortem diagnosis, but I cannot predict when or under what conditions this problem and ones similar to it will happen. In this particular case, I am editing an immediate struct at top level. For example: static const sk_stringmap_entry_t field_map_entries[] = { {"class", RWST_CLASS, "class name", NULL}, {"type", RWST_TYPE, "type name", NULL}, {"flowtype", RWST_FLOWTYPE, "flowtype name", NULL}, {"id-flowtype", RWST_FLOWTYPE_ID, "flowtype integer identifier", NULL}, {"sensor", RWST_SENSOR, "sensor name", NULL}, {"id-sensor", RWST_SENSOR_ID, "sensor integer identifier", NULL}, {"describe-sensor", RWST_SENSOR_DESC, "sensor description", NULL}, {"default-class", RWST_DEFAULT_CLASS, "default class name", NULL}, {"default-type", RWST_DEFAULT_TYPE, "default type name", NULL}, {"mark-defaults", RWST_MARK_DEFAULTS, "'+' for default classes, '*' for types", NULL}, {"class:list", RWST_CLASS_LIST, "list of class names", NULL}, {"type:list", RWST_TYPE_LIST, "list of type names", NULL}, {"flowtype:list", RWST_FLOWTYPE_LIST, "list of flowtype names", NULL}, {"id-flowtype:list", RWST_FLOWTYPE_ID_LIST, "list of flowtype integer identifier", NULL}, {"sensor:list", RWST_SENSOR, "list of sensor names", NULL}, {"id-sensor:list", RWST_SENSOR_ID, "list of sensor integer identifier", NULL}, {"default-class:list", RWST_DEFAULT_CLASS_LIST, "list of default class name", NULL}, {"default-type:list", RWST_DEFAULT_TYPE_LIST, "list of default type name", NULL}, }; Note the indentation of that next-to-last line. That's because the syntax thinks it is ((statement-block-intro 4740) (statement-cont 4740)), indent: 12. It thinks the line above it is ((defun-open 4740)), indent: 4. But if I cursor up a few lines before hitting TAB, I get ((brace-list-entry 4557)), indent: 5, and tabbing down from there fixes the problem. This has happened to me three times while adding entries to this struct. I will include the entire file as I am editing it in this bug report, in case someone can recreate it by emptying the struct and typing the stuff in again. This sort of problem happens to me relatively frequently when editing C files, on the order of 1-10 times a day. Usually saving and reloading the file fixes the problem. Sometimes reindenting the section does. If there is any in-situ debugging I can do when this happens again, please let me know. auto-fill-mode (setq c-basic-offset 4 c-comment-only-line-offset '(0 . 0) c-indent-comment-alist '((anchored-comment column . 0) (end-block space . 1) (cpp-end-block space . 2)) c-indent-comments-syntactically-p nil c-block-comment-prefix "* " c-comment-prefix-regexp '((pike-mode .
