dot-mode.el is a minor mode for GNU Emacs that emulates the ‘.’ command in vi.
See: http://wyrick.org/source/elisp/dot-mode/
This mode is written to address one argument in the emacs vs. vi jihad :-) It emulates the vi `redo’ command, repeating the immediately preceding sequence of commands. This is done by recording input commands 7A09 which change the buffer, i.e. not motion commands.
Add to load-path, and (require 'dot-mode).
Run the command dot-mode to start dot-mode, if you want dot-mode to be
enabled in all buffers you can have the sexp (global-dot-mode t) in your
config.
There are three variables that allow you to modify how dot-mode behaves:
dot-mode-verbose
dot-mode-ignore-undo
dot-mode-global-modedot-mode-ignore-undo defaults to t.
When nil, it will record keystrokes that generate an undo just like any other
keystroke that changed the buffer. I personally find that annoying, but if you
want dot-mode to always remember your undo’s:
(setq dot-mode-ignore-undo nil)
Besides, you can always use dot-mode-override to record an undo when you need to (or even M-x undo).
dot-mode-global-mode - defaults to t.
When t, dot-mode only has one keyboard command buffer.
That means you can make a change in one buffer, switch buffers, then repeat the
change.
When set to nil, each buffer gets its own command buffer.
That means that after making a change in a buffer, if you switch buffers, that
change cannot repeated.
If you switch back to the first buffer, your change can then be repeated again.
This has a nasty side effect if your change yanks from the kill-ring (You
could end up yanking text you killed in a different buffer).
If you want to set this to nil, you should do so before dot-mode is activated on
any buffers.
Otherwise, you may end up with some buffers having a local command buffer and
others using the global one.
`C-.’ is bound to dot-mode-execute, which executes the buffer of
stored commands as a keyboard macro.
`C-M-.’ is bound to dot-mode-override, which will cause dot-mode
to remember the next keystroke regardless of whether it
changes the buffer and regardless of the value of the
dot-mode-ignore-undo variable.
`C-c-.’ is bound to dot-mode-copy-to-last-kbd-macro, which will
copy the current dot mode keyboard macro to the last-kbd-macro
variable. It can then be executed via call-last-kbd-macro
(normally bound to `C-x-e’), named via name-last-kbd-macro,
and then inserted into your .emacs via insert-kbd-macro.
Installation of the development environment can be done with cask install.
Tests are written using ecukes, and can be run with cask exec ecukes.
The script ./testrun.sh starts an emacs instance in the environment that the
tests are run under. This instance begins with dot-mode loaded, but not turned
on.
