Linting dotenv files like a charm!

Project description

dotenv-linter Build Status Coverage Github Action Python Version Documentation Status

Simple linter for .env files.


While .env files are very simple it is required to keep them consistent. This tool offers a wide range of consistency rules and best practices.

And it integrates perfectly to any existing workflow.

Installation and usage

pip install dotenv-linter

And then run it:

dotenv-linter .env .env.template

See Usage section for more information.


There are many things that can go wrong in your .env files:

# Next line has leading space which will be removed:

# Equal signs should not be spaced:

# Quotes won't be preserved after parsing, do not use them:
SECRET="my value"

# Beware of duplicate keys!
SECRET=Already defined ;(

# Respect the convention, use `UPPER_CASE`:

And much more! You can find the full list of violations in our docs.


Special thanks goes to Ignacio Toledo for creating an awesome logo for the project.
