Rewrite of plugin/repmo.vim, the script is simpler now, and autoloaded.
With repmo, you can map keys and make them repeatable with a key. Repmo is targeted at motions and scroll commands, because for each mapped key you need to specify an opposite key.
For key mapping there are two functions: repmo#SelfKey() indicates remapping off (required when mapping a builtin key to itself), repmo#Key() indicates remapping on (usually for everything else). The indicator is used by repetition keys.
New Feature: Typing [count]; (given you mapped ;) updates the remembered
count.
There is no plugin file, mappings should be defined in the vimrc.
" map a motion and its reverse motion:
:noremap <expr> h repmo#SelfKey('h', 'l')|sunmap h
:noremap <expr> l repmo#SelfKey('l', 'h')|sunmap l
" if you like `:noremap j gj', you can keep that:
:map <expr> j repmo#Key('gj', 'gk')|sunmap j
:map <expr> k repmo#Key('gk', 'gj')|sunmap k
" repeat the last [count]motion or the last zap-key:
:map <expr> ; repmo#LastKey(';')|sunmap ;
:map <expr> , repmo#LastRevKey(',')|sunmap ,
" add these mappings when repeating with `;' or `,':
:noremap <expr> f repmo#ZapKey('f')|sunmap f
:noremap <expr> F repmo#ZapKey('F')|sunmap F
:noremap <expr> t repmo#ZapKey('t')|sunmap t
:noremap <expr> T repmo#ZapKey('T')|sunmap T
With argument, you can make f remember the count (same for F, t and T):
:noremap <expr> f repmo#ZapKey('f', 1)|sunmap f
Scroll commands work too:
:noremap <expr> <C-E> repmo#SelfKey('<C-E>', '<C-Y>')
:noremap <expr> <C-Y> repmo#SelfKey('<C-Y>', '<C-E>')
Alternative repetition keys (also working in addition to ; and ,):
" repeat the last [count]motion:
:map <expr> <Space> repmo#LastKey('')|sunmap <Space>
:map <expr> <BS> repmo#LastRevKey('')|sunmap <BS>
g:repmo_require_count boolean (default 0)
If non-zero, a repetition key like ; only repeats the last motion for which a count was given. This used to be the only available option. If zero, ; repeats any last motion, this is the new default! You can change the value at any time.
If you want the old behavior back, put in your vimrc
:let g:repmo_require_count = 1
If you want to use ; and , for repetition, then this may raise conflicts with foreign scripts. But you can set up repmo to work together with many of these scripts:
Make it work with Fanfingtastic:
" Do not map fanfingtastic keys:
:let g:fing_enabled = 0
:map <expr> ; repmo#LastKey('<Plug>fanfingtastic_;')|sunmap ;
:map <expr> , repmo#LastRevKey('<Plug>fanfingtastic_,')|sunmap ,
:map <expr> f repmo#ZapKey('<Plug>fanfingtastic_f')|sunmap f
:map <expr> F repmo#ZapKey('<Plug>fanfingtastic_F')|sunmap F
:map <expr> t repmo#ZapKey('<Plug>fanfingtastic_t')|sunmap t
:map <expr> T repmo#ZapKey('<Plug>fanfingtastic_T')|sunmap T
or if you like Sneak:
map <expr> ; repmo#LastKey('<Plug>Sneak_;')|sunmap ;
map <expr> , repmo#LastRevKey('<Plug>Sneak_,')|sunmap ,
map <expr> s repmo#ZapKey('<Plug>Sneak_s')|ounmap s|sunmap s
map <expr> S repmo#ZapKey('<Plug>Sneak_S')|ounmap S|sunmap S
omap <expr> z repmo#ZapKey('<Plug>Sneak_s')
omap <expr> Z repmo#ZapKey('<Plug>Sneak_S')
map <expr> f repmo#ZapKey('<Plug>Sneak_f')|sunmap f
map <expr> F repmo#ZapKey('<Plug>Sneak_F')|sunmap F
map <expr> t repmo#ZapKey('<Plug>Sneak_t')|sunmap t
map <expr> T repmo#ZapKey('<Plug>Sneak_T')|sunmap T
The odd term "zap-key" means one of f, F, t, T, ; or , (no text is deleted!).
Requires a not-too-old Vim which correctly handles a [count] typed before an <expr> mapping.
The leading colons are only for readability, nevertheless Vim treats them as whitespace.
Looks like vim-expand-region has a similar purpose.
