Some programs use CamelCaseWords (or camelCaseWords). The following maps allow you to move word by word, for example, from the 'C' of Camel, to the 'C' of Case, to the 'W' of Words. Some alternate versions are given, starting with something simple and more easily understood.
Simple move
nnoremap <C-Left> :call search('\<\<Bar>\u', 'bW')<CR>
nnoremap <C-Right> :call search('\<\<Bar>\u', 'W')<CR>
inoremap <C-Left> <C-o>:call search('\<\<Bar>\u', 'bW')<CR>
inoremap <C-Right> <C-o>:call search('\<\<Bar>\u', 'W')<CR>
Better handling of all-uppercase words
Here is a more thorough version. It does not go through a CAPITALIZED word one character at a time.
nnoremap <silent><C-Left> :<C-u>call search('\<\<Bar>\U\@<=\u\<Bar>\u\ze\%(\U\&\>\@!\)\<Bar>\%^','bW')<CR>
nnoremap <silent><C-Right> :<C-u>call search('\<\<Bar>\U\@<=\u\<Bar>\u\ze\%(\U\&\>\@!\)\<Bar>\%$','W')<CR>
inoremap <silent><C-Left> <C-o>:call search('\<\<Bar>\U\@<=\u\<Bar>\u\ze\%(\U\&\>\@!\)\<Bar>\%^','bW')<CR>
inoremap <silent><C-Right> <C-o>:call search('\<\<Bar>\U\@<=\u\<Bar>\u\ze\%(\U\&\>\@!\)\<Bar>\%$','W')<CR>
Enhanced version
With the following, the cursor will stop at:
- The beginning of a word.
- The beginning of a run of camel characters.
- A camel character followed by a run of non-camel characters.
- The start and end of the file.
" Use one of the following to define the camel characters.
" Stop on capital letters.
let g:camelchar = "A-Z"
" Also stop on numbers.
let g:camelchar = "A-Z0-9"
" Include '.' for class member, ',' for separator, ';' end-statement,
" and <[< bracket starts and "'` quotes.
let g:camelchar = "A-Z0-9.,;:{([`'\""
nnoremap <silent><C-Left> :<C-u>call search('\C\<\<Bar>\%(^\<Bar>[^'.g:camelchar.']\@<=\)['.g:camelchar.']\<Bar>['.g:camelchar.']\ze\%([^'.g:camelchar.']\&\>\@!\)\<Bar>\%^','bW')<CR>
nnoremap <silent><C-Right> :<C-u>call search('\C\<\<Bar>\%(^\<Bar>[^'.g:camelchar.']\@<=\)['.g:camelchar.']\<Bar>['.g:camelchar.']\ze\%([^'.g:camelchar.']\&\>\@!\)\<Bar>\%$','W')<CR>
inoremap <silent><C-Left> <C-o>:call search('\C\<\<Bar>\%(^\<Bar>[^'.g:camelchar.']\@<=\)['.g:camelchar.']\<Bar>['.g:camelchar.']\ze\%([^'.g:camelchar.']\&\>\@!\)\<Bar>\%^','bW')<CR>
inoremap <silent><C-Right> <C-o>:call search('\C\<\<Bar>\%(^\<Bar>[^'.g:camelchar.']\@<=\)['.g:camelchar.']\<Bar>['.g:camelchar.']\ze\%([^'.g:camelchar.']\&\>\@!\)\<Bar>\%$','W')<CR>
vnoremap <silent><C-Left> :<C-U>call search('\C\<\<Bar>\%(^\<Bar>[^'.g:camelchar.']\@<=\)['.g:camelchar.']\<Bar>['.g:camelchar.']\ze\%([^'.g:camelchar.']\&\>\@!\)\<Bar>\%^','bW')<CR>v`>o
vnoremap <silent><C-Right> <Esc>`>:<C-U>call search('\C\<\<Bar>\%(^\<Bar>[^'.g:camelchar.']\@<=\)['.g:camelchar.']\<Bar>['.g:camelchar.']\ze\%([^'.g:camelchar.']\&\>\@!\)\<Bar>\%$','W')<CR>v`<o
Alternatives
The camelcasemotion script is based on this tip, but much refined and enhanced. It can move through both CamelCase and underscore_notation words. It provides configurable mappings for normal mode, operator-pending mode and visual mode, plus a corresponding "inner" text object. -- Inkarkat 12:12, 5 April 2009 (UTC)
