Motely (MotelyJAML)

Motely is a vectorized (SIMD) seed-search engine for Balatro. Filters are authored in JAML (Jimbo's Ante Markup Language).

Build

dotnet build Motely.slnx

Test

dotnet test Motely.Tests/Motely.Tests.csproj
dotnet test Motely.Tests/Motely.Tests.csproj --filter "FullyQualifiedName~SomeTestName"

Toolchain

• .NET 10 SDK, pinned to 10.0.204 in global.json (rollForward: latestFeature).

Layout

The solution is Motely.slnx. Projects:

• Motely/ — the core engine (vectorized SIMD seed search).
• Motely.CLI/ — command-line head.
• Motely.TUI/ — terminal UI head.
• Motely.Wasm/ — WebAssembly head (Bootsharp interop).
• Motely.DataLake/ — data/results tooling.
• Motely.Tests/ — the test project.

Other top-level items: JamlFilters/ (pre-made .jaml filter configs), jaml-lang/ (the JAML language), Seeds/, and docs/ (balatro-mechanics.md).

JAML

Filters are written in JAML — a YAML-based config describing what to look for in a seed. See JamlFilters/ for ready-made filters to copy and adapt, jaml-lang/ for the language service, and docs/balatro-mechanics.md for the game mechanics filters target.

JAML language tooling (LSP, grammar, editor support)

JAML is a real language with real tooling, all generated from the engine:

• jaml-lang/ — the language service (diagnostics, completions, hover, document symbols). Its vocab and key tables (src/generated.ts) are generated by jaml-lang/generate.mjs from Motely/Enums and the JAML clause model — the C# engine is the only source of truth. Generation runs automatically on every Motely.Wasm build; run it by hand with node jaml-lang/generate.mjs.
• jaml-lsp/ — the LSP server (stdio) and VS Code extension. The TextMate grammar (jaml-lsp/syntaxes/jaml.tmLanguage.json) is generated alongside the vocab — never edit it by hand.

node jaml-lang/generate.mjs          # regenerate vocab + grammar from the engine
cd jaml-lang;  npm install; npm run build   # build the language service
cd ../jaml-lsp; npm install; npm run build  # build the LSP server + extension
npm run smoke                        # drive the server over real LSP JSON-RPC

A typo'd joker name, an unknown clause key, or a bad deck value squiggles in your editor with the same judgement the engine itself would pass — because the tables came from the engine.

Finding a Balatro Seed

See FIND_BALATRO_SEED_WITH_MOTELY_CLI.md for the full guide — JAML authoring, CLI flags, gotchas, worked examples.

Quick start:

dotnet run --project Motely.CLI -- --jaml yourfilter --keyword YOURNAME --cutoff 0

The filter lives in JamlFilters/yourfilter.jaml. Run from the repo root so --jaml resolves correctly.

JAML Language Server (LSP)

A real Language Server Protocol implementation lives in jaml-lsp/. It provides:

• Diagnostics — instant validation of syntax, unknown keys, and invalid enum values
• Completion — context-aware suggestions for jokers, cards, decks, stakes, etc.
• Hover — documentation on every JAML key and value
• Document symbols — outline of must / should / mustNot clauses

The vocabulary is generated from the Motely C# engine enums — one source of truth, no drift. See docs/EDITOR_INTEGRATION.md for setup in VS Code, Neovim, Helix, Zed, and Claude Code.

Working with agents

CLAUDE.md covers how AI agents should work in this repo (consent, running policy, the Bootsharp docs). This README is the human-facing source of truth for what Motely is and how to build it.
