Borkdude Skill: ClojureScript Runtime Selection

Status: ✅ Production Ready Trit: 0 (ERGODIC - runtime neutral) Principle: Right tool for context Author: Michiel Borkent (@borkdude)

Overview

Borkdude provides guidance for selecting the appropriate ClojureScript runtime based on execution context. Named after Michiel Borkent, creator of Babashka, SCI, Cherry, Squint, and other Clojure tools.

Runtime Matrix

Decision Tree

Start
  │
  ├── Need fast startup? ─────────► Babashka (bb)
  │
  ├── Browser target?
  │     ├── Minimal bundle? ──────► Squint
  │     ├── Full ClojureScript? ──► Cherry  
  │     └── Script tag? ──────────► Scittle

  ├── Node scripting? ────────────► nbb
  │
  └── Embedded interpreter? ──────► SCI

Commands

# Babashka (scripting)
bb script.clj

# nbb (Node)
npx nbb script.cljs

# Squint (compile to JS)
npx squint compile src/main.cljs

# Cherry (compile with macros)
npx cherry compile src/main.cljs

# Scittle (browser)
# <script src="https://cdn.jsdelivr.net/npm/scittle@0.6.15/dist/scittle.js"></script>

SCI (Small Clojure Interpreter)

Embedded interpreter for sandboxed evaluation:

(require '[sci.core :as sci])

(def ctx (sci/init {:namespaces {'user {'foo (fn [] "bar")}}}))

(sci/eval-string* ctx "(user/foo)")
;; => "bar"

Cherry vs Squint

Babashka Pods

Extend Babashka with pods:

(require '[babashka.pods :as pods])

(pods/load-pod 'org.babashka/go-sqlite3 "0.1.0")
(require '[pod.babashka.go-sqlite3 :as sqlite])

(sqlite/execute! "test.db" ["CREATE TABLE users (id INTEGER PRIMARY KEY)"])

Integration with Music Topos

;; Use Babashka for scripts
(ns ruler.propagate
  (:require [babashka.fs :as fs]))

;; Use SCI for embedded color evaluation
(def color-ctx
  (sci/init {:namespaces 
             {'gay {'color-at (fn [idx] (gay/color-at idx))}}}))

When to Use Each

Babashka

• Shell scripts
• Build automation
• CLI tools
• Data processing

SCI

• Sandboxed evaluation
• Plugin systems
• Configuration DSLs
• Interactive REPLs

Cherry

• Full CLJS features in browser
• Macro-heavy code
• CLJS library compat

Squint

• Minimal JS output
• JS-first interop
• Small bundles

Scittle

• Browser scripting
• No build step
• Quick prototypes

nbb

• Node.js scripting
• npm library access
• Server scripts

Example: Skill Propagation

#!/usr/bin/env bb
;; .ruler/propagate.clj

(require '[babashka.fs :as fs]
         '[clojure.string :as str])

(defn propagate-skill! [skill-name]
  (let [source (str ".ruler/skills/" skill-name "/SKILL.md")
        content (slurp source)]
    (doseq [agent ["codex" "claude" "cursor"]]
      (let [target (str "." agent "/skills/" skill-name "/SKILL.md")]
        (fs/create-dirs (fs/parent target))
        (spit target content)))))

(propagate-skill! "unworld")

Scientific Skill Interleaving

This skill connects to the K-Dense-AI/claude-scientific-skills ecosystem:

Graph Theory

• networkx [○] via bicomodule
  • Universal graph hub

Bibliography References

• general: 734 citations in bib.duckdb

Cat# Integration

This skill maps to Cat# = Comod(P) as a bicomodule in the equipment structure:

Trit: 0 (ERGODIC)
Home: Prof
Poly Op: ⊗
Kan Role: Adj
Color: #26D826

GF(3) Naturality

The skill participates in triads satisfying:

(-1) + (0) + (+1) ≡ 0 (mod 3)

This ensures compositional coherence in the Cat# equipment structure.
