When using split windows in VIM, sometimes I create new split of a file already opened in another split (typically with plugins that open a unit test for given file in a new split).
Is there a way how to remap split command so that it checks whether the file is already opened before splitting, and if it is, give a focus on it?
You can't remap the existing split
command, as far as I know, but you can achieve the same same effect by writing a new function Split
and then using a command-mode abbreviation (cabbrev
).
Here's a function/mapping that should do what you want.
function! MySplit( fname )
let bufnum=bufnr(expand(a:fname))
let winnum=bufwinnr(bufnum)
if winnum != -1
" Jump to existing split
exe winnum . "wincmd w"
else
" Make new split as usual
exe "split " . a:fname
endif
endfunction
command! -nargs=1 Split :call MySplit("<args>")
cabbrev split Split
Note that this will only "check" for existing splits in the current tab, and hidden buffers are ignored. (However, it shouldn't be too difficult to add more cases to enhance this functionality.)
