DetectSpellLang

Introduction

This Vim plug-in autodetects the spell-check language in which the text of of a newly or recently (that is, after typing a couple of words) opened buffer is written. It depends on the spell checker aspell (which is contained in many Linux distributions by default, in Mac OS, and also available for Microsoft Windows, where the path to its executable must be added to the %PATH% environment variable).

Setup

This plug-in only acts on buffers that are spell checked, that is, &l:spell is set. To ensure that certain file types, such as text, markdown and mail, are spell checked, add either the line

  autocmd FileType text,markdown,mail setlocal spell

or the line

  setlocal spell

to text.vim, markdown.vim and mail.vim in ~/.vim/ftplugin (on Microsoft Windows, in %USERPROFILE%\vimfiles\ftplugin).

The spell-check language is detected in-between those listed in the variable g:guesslang_langs. It is empty by default and must be set by the user, choosing the appropriate spell-check languages among the output of the command aspell dicts! For example,

    let g:guesslang_langs = [ 'en_US', 'de_DE', 'es', 'it' ]
