Environment Variables

Regolith supports usage of environment variables in various contexts:

• Go-Simple-Eval expressions

• Filters can access them in their code.

• The preShell and posShell properties of profiles can set them using shell commands.

This section provides an overview of how to work with environment variables in Regolith.

.env File

Regolith supports loading environment variables from a .env file located in the root of your project directory. This file should contain key-value pairs in the format KEY=VALUE, one per line. For example:

SOME_VAR=Hello, World!
SOME_OTHER_VAR=Some other value

–env Flag

The --env flag can be used with any Regolith command. It allows you to specify a custom path to a .env file.

For example if you want to run regolith with a custom .env file, you can use the following command:

regolith run --env ./path/to/env/file
