A python library and CLI for the LanguageTool JSON API

Project description

travis license Latest Version pypi_versions

A python library and CLI for the LanguageTool JSON API.

LanguageTool is an open source spellchecking platform. It supports a large variety of languages and has advanced grammar support.

Installation

pyLanguagetool can be installed with pip/pipenv:

pip install pylanguagetool
# or via pipenv
pipenv install pylanguagetool

Basic Usage

# pipe text to pylanguagetool
echo "This is a example" | pylanguagetool

# read text from a file
pylanguagetool textfile.txt

# read text from stdin
pylanguagetool < textfile.txt

# read text from the systems clipboard
pylanguagetool -c # get text from system clipboard

All samples above will return a list of detected errors and possible replacements.

# Use "an" instead of 'a' if the following word starts with a vowel sound, e.g. 'an article', 'an hour'
#   ✗ This is a example
#             ^
#   ✓ This is an example

Configuration

All LanguageTool API parameters can be set via command line arguments, environment variables or a configuration file (~/.config/pyLanguagetool.conf) For more information about the configuration file syntax, read the ConfigArgParse documentation.

Parameters

$ pylanguagetool --help
usage: pylanguagetool [-h] [-v] [-a API_URL] [--no-color] [-c] [-s]
                      [-t {txt,html,md,rst,ipynb}] [-l LANG]
                      [-m MOTHER_TONGUE] [-p PREFERRED_VARIANTS]
                      [-e ENABLED_RULES] [-d DISABLED_RULES]
                      [--enabled-categories ENABLED_CATEGORIES]
                      [--disabled-categories DISABLED_CATEGORIES]
                      [--enabled-only] [--pwl PWL]
                      [input file]

Args that start with '--' (eg. -v) can also be set in a config file
(~/.config/pyLanguagetool.conf). Config file syntax allows: key=value,
flag=true, stuff=[a,b,c] (for details, see syntax at
https://pypi.org/project/ConfigArgParse/). If an arg is specified in more than
one place, then commandline values override environment variables which
override config file values which override defaults.

positional arguments:
  input file            input file

optional arguments:
  -h, --help            show this help message and exit
  -v, --verbose         [env var: VERBOSE]
  -a API_URL, --api-url API_URL
                        the URL of the v2 languagetool API, should end with
                        '/v2/' [env var: API_URL]
  --no-color            don't color output [env var: NO_COLOR]
  -c, --clipboard       get text from system clipboard [env var: CLIPBOARD]
  -s, --single-line     check every line on its own [env var: SINGLE_LINE]
  -t {txt,html,md,rst,ipynb}, --input-type {txt,html,md,rst,ipynb}
                        if not plaintext [env var: CLIPBOARD]
  -l LANG, --lang LANG  A language code like en or en-US, or auto to guess the
                        language automatically (see preferredVariants below).
                        For languages with variants (English, German,
                        Portuguese) spell checking will only be activated when
                        you specify the variant, e.g. en-GB instead of just
                        en. [env var: TEXTLANG]
  -m MOTHER_TONGUE, --mother-tongue MOTHER_TONGUE
                        A language code of the user's native language,
                        enabling false friends checks for some language pairs.
                        [env var: MOTHER__TONGUE]
  -p PREFERRED_VARIANTS, --preferred-variants PREFERRED_VARIANTS
                        Comma-separated list of preferred language variants.
                        The language detector used with language=auto can
                        detect e.g. English, but it cannot decide whether
                        British English or American English is used. Thus this
                        parameter can be used to specify the preferred
                        variants like en-GB and de-AT. Only available with
                        language=auto. [env var: PREFERRED_VARIANTS]
  -e ENABLED_RULES, --enabled-rules ENABLED_RULES
                        IDs of rules to be enabled, comma-separated [env var:
                        ENABLED_RULES]
  -d DISABLED_RULES, --disabled-rules DISABLED_RULES
                        IDs of rules to be disabled, comma-separated [env var:
                        DISABLED_RULES]
  --enabled-categories ENABLED_CATEGORIES
                        IDs of categories to be enabled, comma-separated [env
                        var: ENABLED_CATEGORIES]
  --disabled-categories DISABLED_CATEGORIES
                        IDs of categories to be disabled, comma-separated [env
                        var: DISABLED_CATEGORIES]
  --enabled-only        enable only the rules and categories whose IDs are
                        specified with --enabled-rules or --enabled-categories

  --pwl PWL, --personal-word-list PWL
                        File name of personal dictionary. A private dictionary
                        can be used to add special words that would otherwise
                        be marked as spelling errors. [env var:
                        PERSONAL_WORD_LIST]

Privacy

By default pyLanguagetool sends all text via HTTPS to the LanguageTool server (see their privacy policy). You can also setup your own server and use it by changing the --api-url attribute.
