With regex input supported, for example, these jumps would be possible:

" Alternative searching, flexibility improved
nnoremap g/ :call sneak#wrap('', 99, 0, 2, 1)<CR>\v
" Jump around word boundaries, accuracy improved
nnoremap \\w :call sneak#wrap('', 4, 0, 2, 1)<CR>\v<

Add an option to support optional regex input

Fix justinmk#104. This should support more flexibility in customisation. With
this option enabled, only input text not containing "\v, \V, \m, \M" are
treated literal.

Thank you! What are some example inputs that you use? I can use those examples to add some tests.

Fix justinmk#104. This should support more flexibility in customisation. With
this option enabled, input text not matching '^\\[vVmM].' are still
treated literal.

I suppose the the pattern parsing is correct. But there are probably problems when inputting patterns in vmap, omap or in streak mode. Additional integration would be done.

My initial intention for adding pattern input is that, by defining specific mappings, we can jump to common text objects, which is currently all I need. I define a simple wrapper function and some mappings which seems work well.

function! Sneak(pre, post, reverse)
  let n = getchar()
  if n == 27 | return | endif
  let c = nr2char(n)
  call sneak#to('', a:pre.c.a:post, 1, 1, 0, a:reverse, 2, 0)
endfunction
nnoremap <silent> 8w  :call Sneak('\v<',      '',       0)<CR>
nnoremap <silent> 8b  :call Sneak('\v<',      '',       1)<CR>
nnoremap <silent> 8e  :call Sneak('\v',       '>',      0)<CR>
nnoremap <silent> 8ge :call Sneak('\v',       '>',      1)<CR>
nnoremap <silent> 9w  :call Sneak('\v\_s\zs', '',       0)<CR>
nnoremap <silent> 9b  :call Sneak('\v\_s\zs', '',       1)<CR>
nnoremap <silent> 9e  :call Sneak('\v',       '\ze\_s', 0)<CR>
nnoremap <silent> 9ge :call Sneak('\v',       '\ze\_s', 1)<CR>

Support regex input mode
59061b5 
Prefix input text with '\v', '\m' or '\M' to turn on "regex mode".

This doesn't break search of "literal text" whose length is less than 3.
Because only text matching '^\\[vVmM].' are not literal any more, which
is identical to what "literal text" means in Vim search pattern starting
with '\V'.

Systemic adjustments are needed for utilizing "regex mode", which is
better to be served by the author.

Close justinmk#104.
