Monorepo versioning, changelog, and Hex publishing for Elixir.

Releaser provides a complete toolkit for managing multi-package Elixir projects (poncho or umbrella). It handles version bumping with pre-release tags, cascading version changes through dependency graphs, changelog generation from git commits, and topological publishing to Hex.

Features

• Versioning — SemVer bump with pre-release tags (dev, beta, rc), cascade to dependents
• Publishing — Publish all packages to Hex in dependency order, replacing path: deps automatically
• Changelog — Generate changelogs from conventional git commits
• Hooks — Pre/post-bump hooks for git tagging, changelog generation, custom logic
• Status — Compare local versions against Hex to see what needs publishing

Quick start

Add to your root mix.exs:

{:releaser, "~> 0.1", only: :dev, runtime: false}

Then use:

mix releaser.bump my_app patch --tag dev
mix releaser.graph
mix releaser.status
mix releaser.publish --dry-run

Configuration

Configure in your root mix.exs project config:

def project do
  [
    app: :my_project,
    releaser: [
      apps_root: "apps",
      changelog: [anchors: %{"feat" => "Added", "fix" => "Fixed"}],
      hooks: [post: [Releaser.Hooks.GitTag]],
      publisher: [package_defaults: [licenses: ["MIT"]]]
    ]
  ]
end

See Releaser.Config for all options.
