Install style-analyzer with pip:
pip3 install lookout-style
Create a fork of the GitHub repository you wish to run analysis against. Let's suppose it is "node". Get another GitHub Personal Access Token with "repo" permissions.
Then package and run the "format" analyzer:
analyzer package lookout.style.format -y -u github-user -t personal-access-token -r github-user/node -w /tmp/pkg
Here comes the tricky part: we need to override the version of JavaScript driver in Babelfish.
docker exec pkg_bblfsh_1 bblfshctl driver remove javascript
docker exec pkg_bblfsh_1 bblfshctl driver install javascript bblfsh/javascript-driver:v1.2.0
Now you can create a new pull request to your fork and watch the analysis run.
