Overview

CLI entry point for kettle-jem-appraisals.

Auto-detects mode (+scaffold+ vs resolve) based on config state, or accepts explicit --scaffold / --resolve flags.

In scaffold mode, reads the project gemspec, excludes standard-library gems, and writes a skeleton appraisal_matrix into .structuredmerge/kettle-jem.yml with tier1 candidates.

In resolve mode, queries RubyGems for version data, assigns gem versions to Ruby-series buckets, generates modular gemfiles, an Appraisals file, and workflow strategy matrix snippets.

Examples:

Run from the command line

Kettle::Jem::Appraisals::CLI.run(["--resolve"])

Instantiate and run

cli = Kettle::Jem::Appraisals::CLI.new(["--scaffold"], project_dir: "/path/to/gem")
cli.run

<<~USAGE
  Usage: kettle-jem-appraisals [--scaffold | --resolve] [--force]

  Generates an Appraisal matrix for the gem in the current directory.
  Without a mode flag, scaffolds appraisal_matrix in #{CONFIG_FILE} when it
  has no resolved versions, and resolves it otherwise.

  Options:
    --scaffold     Force scaffold mode (even if config exists)
    --resolve      Force resolve mode
    --force        Bypass freshness TTL and re-resolve
    -v, --version  Print the version and exit
    -h, --help     Print this help and exit

  !%w[false no off none never 0].include?(value.to_s.strip.downcase)
end

#annotate_activerecord_support(appraisal_entries, tier1_gems, matrix) ⇒ void

This method returns an undefined value.

Generates the ActiveRecord database support gemfiles the matrix needs and adds the one matching each ActiveRecord entry's version to its extra gemfiles. Warns when no sqlite3 release an entry's support gemfile allows fixes an advisory. Skipped when disabled via activerecord_support, when activerecord is not a tier1 gem, or when appraisal_gemfiles already names a support gemfile.

Parameters:

  • appraisal_entries (Array[Hash[Symbol, untyped]])
  • tier1_gems (Array[Hash[String, untyped]])
  • matrix (Hash[String, untyped])
