brew tap julien-blanchon/homebrew-tap
# Then install montelimar
brew install --cask montelimar

You can also manually download the .dmg in the Github Release section.

Getting Started

Prerequisites

• Bun - Fast all-in-one JavaScript runtime & package manager
• uv - Fast Python package installer
• Rust - For Tauri's backend

Development Setup

1. Install the project dependencies for javascript

bun install

2. Python Sidecar Setup:

# Navigate to src-python directory and create a virtual environment
cd src-python
# Create a virtual environment
uv venv
# Activate the virtual environment
source .venv/bin/activate
# Sync the dependencies
uv sync

The Python sidecar (backend) is packaged using box-packager, which:

• Takes the entry point defined in pyproject.toml (backend.endpoint:main)
• Bundles all dependencies into a single executable
• Places the executable in src-tauri/binaries with platform-specific naming
• Uses PyApp to bootstrap the Python environment at runtime

3. Build the Python Sidecar:

# This command will:
# 1. Package the Python app using box-packager
# 2. Copy the executable to src-tauri/binaries
# 3. Name it appropriately for your platform
bun run python:package:build

# Initialize the packaged environment
bun run python:package:reset

4. Start Development Server:

# This will:
# 1. Start the Svelte dev server
# 2. Launch the Tauri window
# 3. Initialize the Python sidecar for OCR
bun run tauri dev

Building for Production

# Build the complete application:
# 1. Checks if Python sidecar needs rebuilding
# 2. Rebuilds sidecar if needed
# 3. Builds the Tauri application
bun run tauri build

The built application will be available in src-tauri/target/release.

Development Workflow

Frontend Development (SvelteKit + Tauri)

• src/ - SvelteKit frontend code
• src-tauri/ - Tauri backend code
• Hot reload enabled for both frontend and Rust changes

Python Sidecar Development

• src-python/ - Python OCR service code

• Development mode: bun run python:package:dev

• API development:

  # Generate OpenAPI specs from Python service
  bun run python:package:generate-openapi
  
  # Generate TypeScript client from OpenAPI specs
  bun run python:package:generate-client
  

Asset Generation

• bun run icon:generate - Generate app icons from SVG
• bun run icon:generate-tray - Generate animated tray icons
