dimgigov 10e4ec07d6 docs: reorganize into en/ and bg/ subfolders with numbered indices
- New docs/index.md with language selector
- docs/en/ — 01-getting-started, 02-architecture, 03-ai-integration,
  04-api-reference, 05-user-guide, 06-roadmap
- docs/bg/ — same structure in Bulgarian
- Root README.md trimmed to quick-start + links to docs/
- Removed old flat docs/ files (ARCHITECTURE.md, AI_FIRST.md, etc.)
- Added swap!/reset! examples to getting-started guides

Getting Started

A Clojure dialect that compiles to Nim → C → native binaries.

Prerequisites

  • Nim >= 2.0.0
  • GCC or Clang
  • make
  • curl (for AI features, optional)

Installation

git clone https://gitlab.com/balvatar/lisp-nim.git
cd lisp-nim
make build

Verify Installation

make check    # build + 276+ tests + all examples

CLI Commands

Command Description
./cljnim compile <file.clj> Compile to Nim source
./cljnim compile-lib <file.clj> Compile to Nim with exported functions (*)
./cljnim run <file.clj> Compile and run binary
./cljnim read <file.clj> Parse and print AST
./cljnim repl Start human REPL
./cljnim repl --json Start JSON REPL (for AI agents)
./cljnim deps Resolve dependencies from deps.edn
./cljnim -e '<code>' Evaluate expression
./cljnim ai '<description>' Generate Clojure code with AI

Quick Examples

Hello World

;; examples/hello.clj
(println "Hello, Nim world!")
(println (+ 1 2 3))
$ ./cljnim run examples/hello.clj
Hello, Nim world!
6

Functions & Recursion

(defn square [x] (* x x))
(defn factorial [n]
  (if (= n 0)
    1
    (* n (factorial (- n 1)))))

(let [a 5]
  (println (square a))
  (println (factorial a)))

loop/recur

(defn sum [n]
  (loop [acc 0 i 1]
    (if (> i n)
      acc
      (recur (+ acc i) (inc i)))))
(println (sum 10))  ;; => 55

Atoms (REPL)

user> (def a (atom 0))
user> (swap! a inc)
1
user> (reset! a 42)
42
user> (deref a)
42

AI Setup (Optional)

export DEEPSEEK_API_KEY="sk-..."
# or OPENAI_API_KEY, or MIMO_API_KEY

See 03-ai-integration.md for full AI documentation.
