yamlin
A small YAML loader with custom tags for resolving values at load time — secrets from the OS keychain, values from the environment, and async placeholders — then dumps the resolved result back out as plain YAML.
Install
uv add yamlin
Tags
!keychain <service>/<secret id>— looks up a secret viakeyring.!env <NAME>— looks up an environment variable.!sleep <seconds>— waits, then resolves to the number of seconds (useful for testing concurrent resolution).
Example
# config.yaml
database:
password: !keychain myapp/db-password
host: !env DB_HOST
uv run keyring set myapp db-password # store the secret once
export DB_HOST=localhost
yamlin -f config.yaml
database:
host: localhost
password: <value stored in the keychain>
Omit -f to read from stdin, and add -o <file> to write to a file instead
of stdout.
