Cut the first vertical slice through both layers: a runnable
`kitchen view <file>` that reads a Recipe File, parses it, and renders
it styled to the terminal.
@kitchen-md/core exposes a pure, total `parse(input): DocumentAST` built
on a minimal remark pipeline (parse + frontmatter) with a translation
layer to core's own AST types — frontmatter passthrough, HeadingBlock,
ParagraphBlock, and TextNode. remark types never leak into the public
API.
@kitchen-md/bin's `view` subcommand (commander) reads the file and hands
the DocumentAST to a pure `render(ast): string` (chalk, ANSI
auto-suppressed off a TTY). Fallible file I/O is modelled as a neverthrow
Result over a tagged-union CliError, matched at the boundary: stdout on
success, stderr and exit 1 on failure. The command functions sit beside
the import.meta.main-guarded CLI entry so they are testable in-process.
Tests follow ADR 0009's tiers — unit (parse, render), integration (the
view command's Result), and e2e (the binary as a subprocess) — with
coverage, a path-scoped test-report generator, and a prose fixture
rounding out the tooling. ADR 0008 records errors-as-values at the CLI
boundary; ADR 0009 records the testing tiers.
Layer the remaining flake outputs onto the build: a default app pointing at
the compiled binary, a dev shell exposing the pinned Bun, biome, and bun2nix,
a `use flake` .envrc for direnv, and a checks set aggregating the Bun test
tiers, a build-seam smoke check against the Nix-built binary, and biome lint
through the treefmt-nix flake-parts module.
The dev shell and the build share the one pinned nixpkgs-bun input so Bun
cannot drift between them. treefmt's biome reuses the repo's biome.json with
VCS disabled for the sandbox, and packages/core/src/index_test.ts is
reformatted by biome so the new lint gate is green.
Add a flake-parts flake whose default package Bun-compiles the kitchen
CLI into a self-contained native binary, built in the sandbox with
dependencies vendored by bun2nix.
Bun is pinned via a dedicated nixpkgs-bun input (Bun 1.3.13) that
bun2nix follows, so nixpkgs can track unstable without moving the
compile toolchain onto a release that emits empty binaries.
bun2nix is both a flake input and an npm devDependency, and a
postinstall hook keeps the checked-in bun.nix in sync with the lockfile.
Sets up the initial project structure: two packages (@kitchen-md/core
and @kitchen-md/bin), shared tsconfig, shared fixtures, per-package
test stubs (unit, integration, smoke), .gitignore, and project
CLAUDE.md with Conventional Commits convention.
