Hi, I'm writing a simple function to perform "smart" completions with
LaTeX. I would like to use the <tab> key to perform omni completion by
default, but if it produces no output, then it should try key completion (I
use a dictionary with LaTeX keywords).
Is there a way to produce this flow? Currently, when completion can't find
a match, I get the message "Pattern not found". Is there a way to say vim
"when you find no pattern in omni completion, return <c-p>"?
Thanks a lot.
For further details, I attach the current state of my function:
function! Smart_TabComplete_Tex()
" if the pop-up window is shown, go down
if(pumvisible())
return "\<down>"
endif
" get the line to guess what the user wants
let line = getline('.')
" if the line is empty, return \ followed by omni completion
if(match(line, '\S')==-1)
noh
return "\\\<c-x>\<c-o>"
endif
" find the last word in the line
let lastword = matchstr(line, '\S*$')
" if the last word contains some LaTeX-like character, omni completion
if(match(lastword,'[\{}]') != -1)
noh
return "\<c-x>\<c-o>"
endif
" if the last word seems like a folder, file completion
if(match(lastword,'[/]') != -1)
noh
return "\<c-x>\<c-f>"
endif
" if nothing else works, key completion
noh
return "\<c-p>"
endfunction
