Getting Started

The LOVE MetaLanguage is a multi-pass neuro-symbolic compiler. This guide walks you through drafting intent, materializing strict Abstract Syntax Trees, and verifying invariants.

Installation

Install the LOVE MetaLanguage CLI compiler (love-cli) via bun or npm:

# Install LOVE MetaLanguage CLI globally
bun install -g love-metalang-cli

# Initialize a new LOVE programme
love init my-programme
cd my-programme

The Three-Phase Pipeline

Step 1: OPERA Intent Drafting (/logic/auth.love)

Draft logical causality in pseudo-lisp without worrying about strict bracket depths:

;; /logic/auth_flow.love
(def raw_pass "password123")
(def user_name "alice")

(let [hashed_pass (@hash_pass raw_pass)
      payload     (UserPayload user_name hashed_pass)]
  (@sql_write "users" payload))

Step 2: MATERIALIZE AST Nodes (/programmes/auth.edn)

Materialize the .love recipe into strict LOVE_LANG EDN with ring bracket depths:

;; /programmes/auth_flow.edn
{:type :programme
 :body
 [raw_pass . "password123"
  user_name . "alice"
  hashed_pass . [[ @hash_pass [raw_pass] ]]

  [[[[[ @sql_write
    "users"
    [[[ UserPayload ]]] { :name [user_name] :hash [hashed_pass] }
  ]]]]]]}

Step 3: SIMULATE Invariants (/simulations/auth.ini)

Assert expected side-effects and state changes for static verification:

; /simulations/auth_flow.ini
[expected_state]
db_table = "users"
inserted_keys = "name, hash"
hash_matches_raw = false
side_effect_level = 5

Running the Compiler

# Compile and verify simulation invariants
love compile /logic/auth_flow.love --simulate /simulations/auth_flow.ini
