Vim plugin to automatically identify and set the spell language

It detects the language based on the buffer contents through 'mguesser' (http://www.mnogosearch.org/guesser/), which in turn uses "N-Gram-Based Text Categorization".

Decompress the tarball and change to directory sli-x.y.z/. From there, assuming you have a standard Vim setup:

   mkdir -p ~/.vim/plugin
   cp -r SpellLangIdentifier.vim LanguageIdentifier.sh mguesser ~/.vim/plugin
   cp vimrc.sample ~/.vimrc.sli
   cd ~/.vim/plugin/mguesser && make

Please, check out the sample Vim configuration file which you have just copied. If you prefer you can introduce your changes there and source it directly from your personal vimrc (usually ~/.vimrc), by inserting the line source ~/.vimrc.sli.

Make sure you remove or comment out any previous spell checking configuration that might conflict with the new ones.

1. Automatically (just open a text, mail or TeX file, as illustrated in vimrc.sli). It even works on-the-fly while you edit the file, switching the languages on a paragraph basis when working on multi-language documents (configurable).
2. Using shortcuts in normal or insert mode (F5, F6, F7 and F8; F9 to disable spell checking and on-the-fly language identification).
3. Directly: :{range}SpellLangIdentify (identify the language based on {range} lines; default is the whole buffer).

The user can create its own reference language set ("maps") which will guide/bias the language identification. An example would be to create an n-gram frequency file (a map) for words related to the medical literature or, perhaps, to some subset of the English language. Please check out mguesser's documentation for that.

• Unix-like environment (POSIX shell, coreutils, awk, sed, grep, file, ...).

• In order to improve language detection according to the file type at hand, it is recommended (but not required) to have the following utilities installed: detex, ps2ascii, html2text.
