cherrytree 0.1.1

A build tool to pick cherry, bake release branches, and power label-driven development

Cherry Tree

Cherry Tree is a set of tools that were originally designed to help build releases for Apache Superset, but can be use for any other project that wants to implement a similar workflow.

Ideas behind cherrytree include:

• Baking and storing release metadata in static, deterministic config files
• Github label driven development / releases
• Make release files from specifying base reference and Github labels
• Bake release branches/SHAs from said config files
• Follow a base reference + cherries approach

An example build file

cherrytree offers tooling to both:

1. generate a "bake file" from a base git reference along with a set of tagged PRs
2. craft a branch in a target repo from a "bake file"

Here's an example "bake file":

// this is a Hocon formatted file,
// learn more about hocon here https://github.com/lightbend/config/blob/master/HOCON.md
{
  id = "lyft.28.0rc4.1"
  base_ref = 0.28.0rc4
  source_repos = [
    'https://github.com/apache-superset/cherrytree',
    'https://github.com/some_fork/cherrytree',
  ]
  cherries = [
    [5e6efae15563036d98aa9a13affcef38c6957cb1, "Some SHA from either repos above"],
  ]
}

The format is hocon, which is yet another [bet much better] markup language.
