This Emacs package provides several commands to switch between various
line positions, like moving to the beginning/end of code, line or
comment. It is inspired by this EmacsWiki page (some code from this
page is used).
mwim stands for
Move Where I Mean.
If you don't have a wish to read all the text written below, just try the following key bindings and see what happens:
(global-set-key (kbd "C-a") 'mwim-beginning) (global-set-key (kbd "C-e") 'mwim-end)
This package can be installed from MELPA (with
M-x package-install or
For the manual installation, clone the repo, add the directory to =load-path= and add autoloads for the commands you need:
(add-to-list 'load-path "/path/to/mwim-dir") (autoload 'mwim "mwim" nil t) (autoload 'mwim-beginning "mwim" nil t) (autoload 'mwim-end "mwim" nil t) (autoload 'mwim-beginning-of-code-or-line "mwim" nil t) (autoload 'mwim-beginning-of-line-or-code "mwim" nil t) (autoload 'mwim-beginning-of-code-or-line-or-comment "mwim" nil t) (autoload 'mwim-end-of-code-or-line "mwim" nil t) (autoload 'mwim-end-of-line-or-code "mwim" nil t)
As you can see in the gif demonstration:
M-x mwim-beginning-of-code-or-linemoves the point between a first
M-x mwim-end-of-code-or-linemoves the point between the end of code
M-x mwim-beginning-of-line-or-code and =M-x mwim-end-of-line-or-code=
do the same but in a reverse order.
Also there is
M-x mwim-beginning-of-code-or-line-or-comment command
that switches the point between these 3 positions.
You may bind some keys to some of those commands in a usual manner, for example:
(global-set-key (kbd "C-a") 'mwim-beginning-of-code-or-line) (global-set-key (kbd "C-e") 'mwim-end-of-code-or-line) (global-set-key (kbd "<home>") 'mwim-beginning-of-line-or-code) (global-set-key (kbd "<end>") 'mwim-end-of-line-or-code)
shift-selection is supported by all MWIM commands, which
means if you press
Shift with the bound keys (for example,
==), the region of text will be selected (see Emacs manual for
Along with the described simple commands, there are more general commands that allow you to switch between any positions you want:
You can configure switching positions for these commands with
The position functions from these variables are called without arguments and they should return a new point position. For example, after:
(setq mwim-beginning-position-functions (list (lambda () (+ 2 (line-beginning-position))) 'mwim-code-beginning))
M-x mwim-beginning will switch between the third character (the second
counting from 0) on the current line and the code beginning position.
You can also make mode-specific positions by making these variables
local. Let's say, for
emacs-lisp-mode, you want a usual switch
between the code end and line end when you call =M-x mwim-end=; but if
there is a comment on the current line, you want to move to the
beginning of this comment instead of the code end position. You can do
it like this:
(defun my/comment-beginning-or-code-end () (or (mwim-line-comment-beginning) (mwim-code-end))) (defun my/setup-elisp-mwim-positions () (setq-local mwim-end-position-functions '(my/comment-beginning-or-code-end mwim-line-end))) (add-hook 'emacs-lisp-mode-hook 'my/setup-elisp-mwim-positions)
So, if you want to use these commands instead of the Emacs defaults, you can bind them like this:
(global-set-key (kbd "<C-tab>") #'mwim) (global-set-key [remap move-beginning-of-line] #'mwim-beginning) (global-set-key [remap move-end-of-line] #'mwim-end)
Finally, you can define your own commands using
=mwim-move-to-next-position= macro. See the code of
mwim-end commands for examples.
Many thanks to Adam Porter, who wrote mosey.el package, which provides
similar facilities as
mwim.el. Several ideas were taken from it.
