Descriptive flake8 errors in PyCharm

Question

PyCharm does not have a built-in support for flake8 at the moment. But, flake8 can be configured to run as an external tool.

Sometimes, especia

Answer 1

To all the folks, who need:

• run against files using a remote python interpreter with SSH
• who want only flake8 on changed files regarding git status
• who want to pass any other flake8 arguments without pain

To setup that kind of tool in Pycharm:

File | Settings | Tools | Remote SSH External Tools

see below screen for example configuration:

Arguments: -c "flake8 $(git status -s | grep -E '\.py$' | cut -c 4-) --max-line-lengt=120"

In my case the crucial thing was:

1. use /bin/bash instead of flake8 directly
2. Filling the arguments section by -c "whatever args subcommands etc I need here"

For reference:

• $(git status -s | grep -E '\.py$' | cut -c 4-) is responsible for passing locations of files with changes according to git version control

NOTE: to have your flake8 from virtualenv you might want to specify full path like: /z/your_virtual_envs/bin/flake8
