LanguageTool is an Open Source proof­reading software for English, French, German, Polish, and more than 20 other languages.

You can use the LanguageTools with a firefox-plugin.

This is a Dockerfile to get the languagetools running on a system without java.

The Server is running on port 8010, this port should exposed.

$ docker pull silviof/docker-languagetool [...] $ docker run --rm -p 8010:8010 silviof/docker-languagetool 

Or you run it in background via -d-option.

Run with no minimum rights and RAM

docker run --name languagetool \ --cap-drop=ALL \ --user=65534:65534 \ --read-only \ --mount type=bind,src=/tmp/languagetool/tmp,dst=/tmp \ -p 127.0.0.1:8010:8010 \ --memory 412m --memory-swap 500m \ -e EXTRAOPTIONS="-Xmx382M" \ silviof/docker-languagetool:latest 

Route information can be found at https://languagetool.org/http-api/swagger-ui/#/default, an easy route to test that it's running is /v2/languages.

To support ngrams you need an additional volume or directory mounted to the /ngrams directory. For that add a -v to the docker run-command.

docker run ... -v /path/to/ngrams:/ngrams ... 

Download English ngrams with the commands:

mkdir ngrams wget https://languagetool.org/download/ngram-data/ngrams-en-20150817.zip (cd ngrams && unzip ../ngrams-en-20150817.zip) rm -f ngrams-en-20150817.zip 

One can use them using web browser plugin "Local server (localhost)" setting by running:

docker run -d --name languagetool -p 127.0.0.1:8081:8010 -v `pwd`/ngrams:/ngrams:ro --restart=unless-stopped silviof/docker-languagetool
