meissa

Shared public tooling for RigelBuild repositories. Meissa pins the toolchain and exports rumdl, Biome, and their shared Markdown policy.

Exports

The flake exports packages.<system>.rumdl, packages.<system>.biome, and packages.<system>.rumdl-base-config. The last package contains rumdl/base.toml. It also exports devenvModules.default, which adds only rumdl and Biome to PATH and sets RUMDL_BASE_CONFIG to that store file.

Import the module in a consumer's devenv.nix:

{ inputs, ... }:
{
  imports = [ inputs.meissa.devenvModules.default ];
}

Declare Meissa as a devenv input without following the consumer's nixpkgs pin:

inputs:
  meissa:
    url: github:RigelBuild/meissa

Consumer .rumdl.toml files inherit the shared rules and can add local exclusions:

extends = "$RUMDL_BASE_CONFIG"

The policy is the shared [MD0nn] rule set in Compass's .rumdl.toml. Meissa's own development shell also provides Bun, Node.js, and moon from its pinned nixpkgs.

Packages

Packages under packages/ are published to npm as @rigelbuild/<tool> and versioned independently.

Meissa is public: never name or cite a private repository. ref-gate enforces this with ref-gate.config.json.

Releases

Release Please opens one release pull request covering every changed package. When it merges, the release workflow publishes each released package to npm with provenance through trusted publishing. A new package needs one manual first publish before its trusted publisher can be attached.

Local development

Run direnv allow . once, then direnv exec . rumdl check . or direnv exec . bun test. CI runs nix flake check and moon run :ci (lint, markdown, the ref-gate self-check, and every package's typecheck and tests).
