PtcRunner.Dotenv (PtcRunner v0.14.0)

Copy Markdown View Source

Loads environment variables from an explicitly named dotenv file.

Existing process environment variables take precedence over file values. Command frontends use --env-file FILE to choose the exact file; this module does not search the invocation directory or its parents implicitly.

Examples

PtcRunner.Dotenv.load_file(".env")
