check-config — Validate Configuration

Reads .greengate.toml, validates it, and prints all resolved configuration values. Useful for verifying that overrides are applied correctly and that the file has no syntax errors.

Usage

greengate check-config

Behaviour

• If .greengate.toml exists and is valid, prints every resolved value and exits 0.
• If the file contains a TOML syntax or type error, prints a descriptive error and exits 1.
• If no config file is found, prints the built-in defaults that will be used and exits 0.

Examples

# Verify your config file before running the pipeline
greengate check-config

# Combine with a profile to preview merged values
greengate --profile strict check-config

Sample output (valid config)
