6.5 The location list callback *syntastic-loclist-callback*
*SyntasticCheckHook()*
Syntastic also gives you direct access to the list of errors. A function
named |SyntasticCheckHook()| is called by syntastic (if it exists) right
before populating the |location-list| and enabling the notifiers. The function
takes exactly one argument, the list of errors in |location-list| format (see
|getqflist()| for details). format. You can do essentially anything with this
list, as long as you don't change its format, and you don't add or remove
elements.
For example the following function will make the error window smaller if fewer
than 10 errors are found: >
function! SyntasticCheckHook(errors)
if !empty(a:errors)
let g:syntastic_loc_list_height = min([len(a:errors), 10])
endif
endfunction
<
(Please keep in mind however that Vim options |winheight| and |winminheight|
also affect window sizes.)
