More useful word motions for Vim

Build Status

This is one word under Vim's definition:

CamelCaseACRONYMWords_underscore1234
w--------------------------------->w
e--------------------------------->e
b<---------------------------------b

With this plugin, this becomes six words:

CamelCaseACRONYMWords_underscore1234
w--->w-->w----->w---->w-------->w->w
e-->e-->e----->e--->e--------->e-->e
b<---b<--b<-----b<----b<--------b<-b

word definitions

A word (lowercase) is any of the following:

word Example
Camel case words [Camel][Case]
Acronyms [HTML]And[CSS]
Uppercase words [UPPERCASE] [WORDS]
Lowercase words [lowercase] [words]
Hexadecimal literals [0x00ffFF] [0x0f]
Octal literals [0o644] [0o0755]
Binary literals [0b01] [0b0011]
Regular numbers [1234] [5678]
Other characters [~!@#$]

A WORD (uppercase) is any sequence of non-space characters separated by spaces.

Customization

Default word/WORD mappings:

Mode Mapping
nxo w/W
nxo b/B
nxo e/E
nxo ge/gE
xo aw/aW
xo iw/iW
c <C-R><C-W>/<C-R><C-A>

Use g:wordmotion_prefix to apply a common prefix to each of the default word motion mappings.
E.g.,

let g:wordmotion_prefix = '<Leader>'

NOTE: does not apply to the command line mode <C-R><C-W> and <C-R><C-A> mappings.

Use g:wordmotion_mappings to individually replace the default word motion mappings.
E.g.,

let g:wordmotion_mappings = {
\ 'w' : '<M-w>',
\ 'b' : '<M-b>',
\ 'e' : '<M-e>',
\ 'ge' : 'g<M-e>',
\ 'aw' : 'a<M-w>',
\ 'iw' : 'i<M-w>',
\ '<C-R><C-W>' : '<C-R><M-w>'
\ }

Unspecified entries will still use the default mappings.
Set the value to an empty string to disable the mapping.

NOTE: this overrides g:wordmotion_prefix.

Use g:wordmotion_spaces (default '_') to designate extra space characters.
E.g.,

let g:wordmotion_spaces = '_-.'

will produce the following result:

foo_bar-baz.qux
w-->w-->w-->w>w

All options can be applied dynamically by reloading the plugin.
E.g., to disable the w mapping:

let g:wordmotion_mappings['w'] = ''
unlet g:loaded_wordmotion
runtime plugin/wordmotion.vim

then later re-enable it

let g:wordmotion_mappings['w'] = '<M-w>'
unlet g:loaded_wordmotion
runtime plugin/wordmotion.vim

Caveats

There are some special cases with how Vim's word motions work.
E.g.,

Vim:

	^foo [b]ar$ -> dw -> ^foo[ ]$
	^ baz$               ^ baz$

	^[f]oo bar$ -> cw -> ^[ ]bar$

This plugin:

	^foo [b]ar$ -> dw -> ^foo [b]az$
	^ baz$

	^[f]oo bar$ -> cw -> ^[b]ar$

This plugin faithfully follows the motion of w when executing dw and cw, while Vim replaces these two special cases with the behavior of de and ce, respectively.

If you want to restore Vim's special case behavior with dw and cw, you can do this:

nmap dw de
nmap cw ce
nmap dW dE
nmap cW cE
