• Emacs: Xah Fly Keys
• major new version 24.

• Major key change, two commands is combined into one, and with a easier key, detail:
• The key (qwerty d) (dvorak e) now is xah-smart-delete, which does xah-shrink-whitespaces or xah-delete-backward-char-or-bracket-text. (before, it just does the latter)
• The key (qwerty w) (dvorak ,) now does xah-delete-backward-char. (before, it does xah-shrink-whitespaces)

• xah-smart-delete is new.
• xah-delete-backward-char is new.
• xah-shrink-whitespaces improved.

• The following commands have implementation change. Removed using looking-back, to improve speed.
• xah-goto-matching-bracket
• xah-delete-backward-char-or-bracket-text
• xah-delete-forward-bracket-pairs
• xah-extend-selection

• xah-css-complete-or-indent now faster
• xah-elisp-complete-or-indent now faster

• Emacs: Xah Fly Keys

update

• now, abbrev related commands has ergo keys.
• And several keys for inserting unicode brackets are removed. (A bit experimental) Detail:

we had these keys before, was temp, never used by me much:

("TAB 1" . abbrev-prefix-mark)
("TAB 2" . edit-abbrevs)
("TAB 3" . expand-abbrev)
("TAB 4" . expand-region-abbrevs)
("TAB 5" . unexpand-abbrev)
("TAB 6" . add-global-abbrev)
("TAB 7" . add-mode-abbrev)
("TAB 8" . inverse-add-global-abbrev)
("TAB 9" . inverse-add-mode-abbrev)
("TAB 0" . expand-jump-to-next-slot)
("TAB =" . expand-jump-to-previous-slot)

now they have ergo keys (dvorak notation):

("e c r" . expand-region-abbrevs)
("e c t" . edit-abbrevs)
("e c u" . expand-abbrev)

("e c g" . add-mode-abbrev)
("e c c" . add-global-abbrev)
("e c m" . inverse-add-mode-abbrev)
("e c w" . inverse-add-global-abbrev)

("e c f" . unexpand-abbrev)

("e c h" . expand-jump-to-previous-slot)
("e c n" . expand-jump-to-next-slot)
("e c y" . abbrev-prefix-mark)

also, these keys are removed (rarely used):

("e c" . xah-insert-ascii-single-quote) ; ''

• Xah Fly Keys. xah-unicode-list changed format. was list of string, now assoc list.
• The command xah-insert-unicode implementation changed accordingly.
• Added back several keys for commands that insert unicode brackets e.g. xah-insert-corner-bracket . These are useful, but unfamiliar to most american programers. (i use them to markup text, better than markdown's backtick that have problems with code contain it.) might be removed in the future.

• Xah Fly Keys
• change some command's use of set-mark to push-mark, as proper.
• commands changed are
• xah-select-line
• xah-select-text-in-quote
• xah-extend-selection
• xah-cycle-hyphen-lowline-space
• this fixed some rare mysterious bug, where some command pushed mark, but the mark disappeared.

• xah-shrink-whitespaces more fix. now 3 calls removes all whitespace, like before the rewrite.
• xah-shrink-whitespaces, rewrote, now can work in minibuffer. However, behavior is slightly different than before. Before, it always ends up removing all whitespaces after repeated call. Now, either remove all, or leave just one newline. I think the new behavior is actually better.
• Also removed xah-delete-blank-lines, xah-fly-delete-spaces

Xah Emacs Packages update

• Emacs: Xah HTML Mode (xah-html-mode.el)
• xah-html-rename-source-file-path more fix.
• xah-html-any-to-link-hook now work on current path/url or selection. (before, it works on line or selection)
• xah-html-keyboard-shortcut-markup now work on current line or selection. (before, always currentline)
• xah-html-join-tags minor reimplement.
• xah-html-rename-source-file-path now shows relative path in prompt. (instead full). this makes it cleaner and easier to edit. Also colon in filename is replaced by lowline.
• xah-html-any-to-link-hook now by default take current line as input (not guessing filepath or url chars).
• xah-html-validate-xml-buffer lots fix on correctness. now should return true if valid, else false.
• xah-html-validate-xml-dir.
• added xah-html-amazon-url-to-link and integrated to xah-html-any-to-link

• Emacs: Xah Elisp Mode (xah-elisp-mode.el)
• xah-elisp-mode.el added abbrev pt p1 pc and template for print print1 printc

• xah-dired-rename-space-to-underscore fixed a bug when parent dir contains space.

Emacs: Xah Fly Keys

some key changes. now more ergo.

;; here's the new keys (all dvorak notation)
("t a" . xah-reformat-to-sentence-lines)
("t g" . goto-line)
("t n" . goto-char)
("t f" . move-to-column)

;; their old keys are
("t '" . xah-reformat-to-sentence-lines)
("t f" . goto-line)
("t c" . goto-char)
("t g" . move-to-column)

emacs tip: start new emacs instance sans prompt

• make sure your emacs can always start an instance without effecting existing instance. (so that, you can start a new emacs anytime when some job freezes emacs)
• the key is to make sure when you start a new emacs instance, there is no prompt that requires you to answer questions.
• also, do not use emacs server feature. it creates a lot complications.

• how? just start a new emacs instance. if you get any promp, try to change your init so there is no prompt.
