Apple Code Assistant

Professional CLI tool powered by Apple Intelligence for on-device code generation. Features modern terminal UI, real-time streaming, multi-language support, and conversation management.

Inspired by Apple-AI-CLI.

Prerequisites

Rust 1.70+ (edition 2021)
macOS 15+ with Apple Intelligence support (for future integration)
Apple Silicon Mac recommended

Installation

cargo install apple-code-assistant

Then use the apple-code binary:

apple-code --help

Build and run

cargo build
cargo run -- --help

Quick start

# Simple generation
apple-code -p "hello world in Python" -l python --tool-mode

# Summarize a diff (smartcat-style)
git diff | apple-code -p "summarize the changes" --tool-mode --char-limit 8000

# Use a template for tests
apple-code -p "write tests for this function" -T tests --tool-mode

Getting plain code only (no markdown)

By default, some models may still wrap code in ``` fences and add explanations. To force plain code output suitable for files and editors:

# Only code written to the file (no markdown, no explanation)
apple-code -p "implement binary search" -l python --save -o binary_search.py --tool-mode

You can further tighten behavior with a prompt template in config.toml, for example:

[prompts.strict_code]
system = "Never use markdown or explanations. Return only the final code."

Then call:

apple-code -p "implement binary search" -l python -T strict_code --save -o binary_search.py --tool-mode

Examples (from source checkout)

# Interactive mode (REPL with logo, /help, /exit, /history, /sessions)
cargo run -- -i

# Direct code generation with preview
cargo run -- -p "hello world in Python" -l python --preview

# Save to file
cargo run -- -p "quicksort" -l rust --save -o sort.rs

# Copy to clipboard
cargo run -- -p "utility function" --copy

# Use stdin as context (pipe data in, smartcat-style)
git diff | apple-code -p "summarize the changes"
git diff | apple-code -p "summarize the changes" > summary.txt
cat src/main.rs | apple-code -p "add doc comments to this code"

# Use prompt templates from config.toml
apple-code -p "write tests for this function" -T tests
apple-code -p "refactor this module" -T refactor -l rust

# Extend previous conversation in non-interactive mode
apple-code -p "summarize the architecture of this project" --extend-conversation
apple-code -p "now propose improvements" --extend-conversation

# Repeat input before output (useful in editors)
git diff | apple-code -p "apply these changes but fix formatting" --repeat-input --tool-mode

# Limit size of piped/context data and add globbed context files
git diff | apple-code -p "summarize the changes" --char-limit 8000 --context-glob "src/**/*.rs"

# Edit existing file (send file content + prompt to model, write result back)
cargo run -- -p "add error handling" -e src/main.rs

# Configuration
cargo run -- config --list
cargo run -- config --get theme
cargo run -- config --set default_language=python
cargo run -- config --reset

# List models and languages, test API
cargo run -- models
cargo run -- languages
cargo run -- test

Features

Config – Load from .env and ~/.config/apple-code-assistant/config.toml; subcommand config --list/get/set/reset
Terminal UI – ASCII logo, theme (light/dark), bordered code preview
Code generation – Trait-based client (mock included); direct mode with -p and options
REPL – Interactive mode with /help, /exit, /clear, /history, /sessions, /models, /languages, /test
Conversations – Sessions persisted under config dir; /history and /sessions
File operations – --save -o <file>, --edit <file>
Clipboard – --copy (arboard)
Syntax highlighting – syntect in preview and REPL when language is set
Multi-language – 20+ languages and aliases; languages subcommand; validation of --language
Stdin piping – When stdin is not a TTY (e.g. git diff | apple-code -p "…") the piped content is appended to the prompt (smartcat-style)
Prompt templates – Templates configurables dans config.toml, sélectionnés via --template/-T
CLI conversations – --extend-conversation pour réutiliser la dernière session, --repeat-input pour rejouer l’entrée avant la sortie
Context control – --char-limit pour borner la taille de stdin/contexte, --context-glob pour ajouter des fichiers de contexte par glob
Tool mode – --tool-mode pour une sortie brute adaptée aux éditeurs (aucun cadre ni mise en forme)
Signals – Ctrl+C handled with “Operation cancelled”
