action-dotenv-to-setenv

GitHub action to export a .env file to environment variables (via $GITHUB_ENV)

Adapted from https://github.com/madcoda/dotenv-shell

Inputs

env-file

Required Path to the dotenv file. Default ".env".

Outputs

echo "{name}={value}" workflow commands to $GITHUB_ENV.

echo "TEST_DEFAULT_ENVFILE=expected" >> $GITHUB_ENV
echo "TEST_DOTENV_OVERRIDES_DEFAULT=unexpected" >> $GITHUB_ENV
echo "TEST_UNQUOTED=unexpected" >> $GITHUB_ENV
echo "TEST_UNQUOTED=a=1 b=2 c=3" >> $GITHUB_ENV
echo "TEST_SINGLE_QUOTED=1 2 3 4" >> $GITHUB_ENV
echo "TEST_DOUBLE_QUOTED=1 2 3 4" >> $GITHUB_ENV
echo "TEST_INTERPOLATION=a=1 b=2 c=3 d=4" >> $GITHUB_ENV
echo "TEST_EXISTING=new-value" >> $GITHUB_ENV
echo "TEST_DOTENV_OVERRIDES_DEFAULT=expected" >> $GITHUB_ENV
echo "TEST_NO_NEWLINE=still there" >> $GITHUB_ENV

Example Usage

uses: c-py/action-dotenv-to-setenv@v5
with:
  env-file: .env

Usage with NODE_OPTIONS

Unfortunately, NODE_OPTIONS cannot be set in this action due to GitHub security settings. To work around this NODE_OPTIONS is automatically output under node_options.

  - uses: c-py/action-dotenv-to-setenv@v5
    id: source-env
    with:
      env-file: .env
  - run: echo ${{ steps.source-env.outputs.node_options }}
