6. FAQ *UltiSnips-FAQ*
Q: Do I have to call UltiSnips#ExpandSnippet() to check if a snippet is
expandable ? Is there instead an analog of neosnippet#expandable ?
expandable? Is there instead an analog of neosnippet#expandable?
A: Yes there is, try
function UltiSnips#IsExpandable()
return !empty(UltiSnips#SnippetsInCurrentScope())
endfunction
Consider that UltiSnips#SnippetsInCurrentScope() will return all the
snippets you have if you call it after a space character. If you want
UltiSnips#IsExpandable() to return false when you call it after a space
character use this a bit more complicated implementation:
function UltiSnips#IsExpandable()
return !(
\ col('.') <= 1
\ || !empty(matchstr(getline('.'), '\%' . (col('.') - 1) . 'c\s'))
\ || empty(UltiSnips#SnippetsInCurrentScope())
\ )
endfunction
