compiler/diction.vim

Enforce vim script implementation to reduce ambiguities and improve robustness:

scriptversion 4

Configure diction support:

setlocal errorformat=%f:%l:\ %m
setlocal makeprg=diction\ -s\ %

If possible, enable language support:

const s:lang = split(v:lang, '\.')[0]
if filereadable('/usr/share/diction/' .. s:lang)
    let &l:makeprg ..= ' -L ' .. s:lang
endif
