# Smalltalk Skill Execute Smalltalk code and browse live Squeak/Cuis images via MCP. ## Prerequisites **Get the ClaudeSmalltalk repo first:** ```bash git clone https://github.com/CorporateSmalltalkConsultingLtd/ClaudeSmalltalk.git ``` This repo contains: - MCP server code for Squeak (`MCP-Server-Squeak.st`) - Setup documentation (`SQUEAK-SETUP.md`, `CLAWDBOT-SETUP.md`) - This Clawdbot skill (`clawdbot/`) ## Setup 1. **Set up Squeak with MCP server** — see [SQUEAK-SETUP.md](https://github.com/CorporateSmalltalkConsultingLtd/ClaudeSmalltalk/blob/main/SQUEAK-SETUP.md) 2. **Configure Clawdbot** — see [CLAWDBOT-SETUP.md](https://github.com/CorporateSmalltalkConsultingLtd/ClaudeSmalltalk/blob/main/CLAWDBOT-SETUP.md) ## Usage ```bash # Check setup python3 smalltalk.py --check # Evaluate code python3 smalltalk.py evaluate "3 factorial" python3 smalltalk.py evaluate "Date today" # Browse a class python3 smalltalk.py browse OrderedCollection # View method source python3 smalltalk.py method-source String asUppercase # List classes (with optional prefix filter) python3 smalltalk.py list-classes Collection # Get class hierarchy python3 smalltalk.py hierarchy OrderedCollection # Get subclasses python3 smalltalk.py subclasses Collection # List all categories python3 smalltalk.py list-categories # List classes in a category python3 smalltalk.py classes-in-category "Collections-Sequenceable" # Define a new class python3 smalltalk.py define-class "Object subclass: #Counter instanceVariableNames: 'count' classVariableNames: '' poolDictionaries: '' category: 'MyApp'" # Define a method python3 smalltalk.py define-method Counter "increment count := (count ifNil: [0]) + 1. ^ count" # Delete a method python3 smalltalk.py delete-method Counter increment # Delete a class python3 smalltalk.py delete-class Counter ``` ## Commands | Command | Description | |---------|-------------| | `--check` | Verify VM/image paths and dependencies | | `--debug` | Debug hung system (sends SIGUSR1, captures stack trace) | | `evaluate <code>` | Execute Smalltalk code, return result | | `browse <class>` | Get class metadata (superclass, ivars, methods) | | `method-source <class> <selector>` | View method source code | | `define-class <definition>` | Create or modify a class | | `define-method <class> <source>` | Add or update a method | | `delete-method <class> <selector>` | Remove a method | | `delete-class <class>` | Remove a class | | `list-classes [prefix]` | List classes, optionally filtered | | `hierarchy <class>` | Get superclass chain | | `subclasses <class>` | Get immediate subclasses | | `list-categories` | List all system categories | | `classes-in-category <cat>` | List classes in a category | ## Environment Variables | Variable | Description | |----------|-------------| | `SQUEAK_VM_PATH` | Path to Squeak/Cuis VM executable | | `SQUEAK_IMAGE_PATH` | Path to Smalltalk image with MCP server | ## Notes - Requires xvfb for headless operation on Linux servers - Uses Squeak 6.0 MCP server (GUI stays responsive if display available) - `saveImage` intentionally excluded for safety
