Settings

A server's settings, such as its address, its mock files or its log level, come from four places, each overriding the ones before it:

1. Code: mockhttp.Setup() or mockgrpc.Setup(), such as Setup().Addr(":8080").
2. A .vlatterc.yaml, .vlatterc.yml or .vlatterc.json file in the working directory or in testdata.
3. VLATTE_* environment variables.
4. Command-line flags, for the vlatte command.

Each setting has one key that the others derive from: log.level is log: {level: debug} in a file, VLATTE_LOG_LEVEL=debug and --log-level=debug.

# .vlatterc.yaml
addr: ":8080"
log:
  level: debug

Servers in tests read the file and the environment too, unless Setup().ConfigSources() says otherwise.

• Configuration covers the sources in full: how values are written, the root and work directories, and the sources in tests.
• The settings reference lists every setting, with its flag, variable and file key.
