branch: master
commit 2eb492ba0fdb16cdb3e0e3763e8eff80fd50c578
Author: Luke Lee <address@hidden>
Commit: Luke Lee <address@hidden>
Brief mode: add [C-p] for viewing compilation buffer and error messages
* packages/brief/brief.el: fix comments, add C-p and a customized flag
to turn off scroll-bar-mode for emulating Brief editor's "thin borders".
(brief-turn-off-scroll-bar-mode): new custom flag.
(brief-view-compilation-output): for C-p, jump to compilation buffer/
frame/window if there is one. After enters compilation buffer C-p finds
previous compilation error message (while C-n finds next).
(brief-buffer-read-only-toggle): consistent behavior among all Emacs
versions for showing message.
(brief-bookmark-jump-set): correct doc string.

+;; This Extended Brief editor emulator was originally based on the
+;; CRiSP mode emulator (listed below), with extensive rewriting over
+;; 17+ years. Almost all of the original Brief 3.1 Editor keys are
+;; implemented and extended.
+;;
+;; A lot of editor behaviors were also adapted to Emacs. One example
+;; is that this Brief emulator is able to respect `visual-line-mode',
+;; `toggle-truncate-lines' and hidden/abbreviated mode texts (which
+;; usually shown as "..." in Emacs) such as org-mode, hideshow mode
+;; and hideif mode (hide C/C++ "#ifdef" conditional compilation units,
+;; another package that I had rewritten). When texts are hidden at
+;; cursor line, Brief line-oriented commands like line-cut, line-copy,
+;; line-deletion ... will operate on all hidden lines. For a complete
+;; description of the functions extended, search the "brief.el" source
+;; code for ";;; Brief Extension:". Main TOC is:
+;;
+;; * Visual mode, line truncation and hidden texts
+;; * Fast line number computation cache
+;; * Huge clipboard/Xselection texts
+;; * External Xselection helper programs `xsel' and `xclip'
+;; * Fast cursor movement
