README

Dump merged configuration

Load from a YAML file and APP_* environment variables, then write the combined result to a new YAML file with WithFileDumperAs and Dump.

This is handy for debugging -- you can see exactly what Synthra resolved after merging all sources.

Run

cd examples/dump
APP_SERVER_PORT=9090 go run .
cat effective-config.yaml

You can also pass a custom output path:

go run . /tmp/my-config.yaml

Tests

cd examples/dump && go test -v

Key ideas

1. Inspect the merged state -- Dump writes whatever Load produced.
2. Any codec -- WithFileDumperAs accepts codec.YAML, codec.JSON, or codec.TOML.
3. No side effects on Load -- the dumper only writes when you call Dump explicitly.

Package main writes the merged effective configuration to a YAML file.
