language-check on PyPI  

Checks grammar using LanguageTool.

AuthorSteven Myint

Python wrapper for LanguageTool.

This is a fork of that produces more easily parsable results from the command-line.

Example usage

From the interpreter:

>>> import language_check
>>> tool = language_check.LanguageTool('en-US')
>>> text = u'A sentence with a error in the Hitchhiker’s Guide tot he Galaxy'
>>> matches = tool.check(text)
>>> len(matches)

Check out some Match object attributes:

>>> matches[0].fromy, matches[0].fromx
(0, 16)
>>> matches[0].ruleId, matches[0].replacements
('EN_A_VS_AN', ['an'])
>>> matches[1].fromy, matches[1].fromx
(0, 50)
>>> matches[1].ruleId, matches[1].replacements
('TOT_HE', ['to the'])

Print a Match object:

>>> print(matches[1])
Line 1, column 51, Rule ID: TOT_HE[1]
Message: Did you mean 'to the'?
Suggestion: to the

Automatically apply suggestions to the text:

>>> language_check.correct(text, matches)
'A sentence with an error in the Hitchhiker’s Guide to the Galaxy'

From the command line:

$ echo 'This are bad.' > example.txt

$ language-check example.txt
example.txt:1:1: THIS_NNS[3]: Did you mean 'these'?


To install via pip:

$ pip install --upgrade language-check

If you are using Python 2, you’ll need to install 3to2 beforehand:

$ pip install --upgrade 3to2


The installation process should take care of downloading LanguageTool (it may take a few minutes). Otherwise, you can manually download and unzip it into where the language_check package resides.

Vim plugin

To use language-check in Vim, install Syntastic and use the following settings:

let g:syntastic_text_checkers = ['language_check']
let g:syntastic_text_language_check_args = '--language=en-US'

Customize your language as appropriate.
