Overview

Squint is a light-weight ClojureScript dialect that compiles to JavaScript with minimal runtime overhead. It's the "minimal" alternative in borkdude's browser runtime spectrum.

When to Use Squint vs Cherry

Aspect	Squint	Cherry 🍒
Runtime size	Minimal (~10KB)	Full cljs.core (~100KB)
Semantics	JS-like	Full CLJS
Data structures	JS objects/arrays	Persistent immutable
Keywords	Strings	CLJS keywords
Interop	Seamless	Requires macros
JSX	❌	✅
Use case	Small scripts, interop	Full applications

Installation

npm install squint-cljs@latest

Usage

;; example.cljs
(ns example)

;; Functions compile to regular JS functions
(defn greet [name]
  (str "Hello, " name "!"))

;; JS interop is seamless
(js/console.log (greet "World"))

;; Object destructuring works naturally
(defn process [{:keys [a b c]}]
  (+ a b c))

(process #js {:a 1 :b 2 :c 3})  ; => 6

Compile and Run

# Compile to JS
npx squint compile example.cljs

# Run directly
npx squint run example.cljs

Key Differences from CLJS

1. Data structures are JS native:

   {:a 1}  ; => {a: 1} in JS (plain object)
   [1 2 3] ; => [1, 2, 3] in JS (array)
   

2. Keywords become strings:

   :foo ; => "foo" in JS
   

3. No persistent data structures (use JS mutation)

4. Faster interop (no conversion needed)

Integration with Gay.jl Colors

(ns squint.gay-colors)

;; SplitMix64 constants
(def GOLDEN 0x9E3779B97F4A7C15)
(def MASK64 0xFFFFFFFFFFFFFFFF)

(defn splitmix64 [state]
  (let [s (bit-and (+ state GOLDEN) MASK64)
        z (-> s
              (bit-xor (unsigned-bit-shift-right s 30))
              (* 0xBF58476D1CE4E5B9)
              (bit-and MASK64))
        z (-> z
              (bit-xor (unsigned-bit-shift-right z 27))
              (* 0x94D049BB133111EB)
              (bit-and MASK64))]
    (bit-xor z (unsigned-bit-shift-right z 31))))

(defn color-at [seed idx]
  (loop [state seed i idx]
    (if (zero? i)
      (let [v (splitmix64 state)
            l (+ 10 (* 85 (/ (bit-and v 0xFF) 255)))
            c (* 100 (/ (bit-and (unsigned-bit-shift-right v 8) 0xFF) 255))
            h (* 360 (/ (bit-and (unsigned-bit-shift-right v 16) 0xFFFF) 65535))]
        {:L l :C c :H h})
      (recur (splitmix64 state) (dec i)))))
