Spawn

TOML config driven agent to generate data

CircleCIGo Reference

Overview

This is an agent to generate data via a TOML configuration file. Users define a serializer format and call generator functions to generate data at each interval. The generated data is then sent the corresponding outputs.

To create a basic JSON with some random numeric values:

[[generator.randomfloat64]]
id = "float"# id used to reference in serializer template
[[serializer.template]]
id = "json"# id used to reference in outputstemplate = """{ "value": {{ float }} }"""
[[output.stderr]]
serializers = ["json"]

Would produce a different JSON value at each interval in the format:

{ "value": 123.456 }

Install

Pre-build binaries are available on the releases page.

Usage

To generate data use the run subcommand:

./spawn run <toml file>

The other subcommands include:

  • once: To run all serializers and generators once and output to stdout
  • toml: To validate a TOML file

Contributing

Pull requests are welcome. For major changes, please open an issue first to discuss what you would like to change.

Please make sure to update tests as appropriate.

If you find a bug, have a question, or ideas for improvements please file an issue on GitHub.
