TypR CLI

Command-line interface, REPL, and LSP server for TypR - a typed superset of R.

This crate provides the CLI layer for TypR, depending on typr-core for the core logic. It includes:

• Command-line interface with project management commands
• Interactive REPL with syntax highlighting
• Language Server Protocol (LSP) server for IDE integration
• Filesystem-based source and output handlers

Usage

# Create a new project
typr new myproject

# Check types
typr check

# Build to R
typr build

# Run
typr run

# Start REPL
typr repl

# Start LSP server
typr lsp

Architecture

This crate follows the same design philosophy as typr-wasm:

• Minimal wrapper - Only CLI-specific code, no business logic
• Uses typr-core abstractions - Implements SourceProvider for filesystem
• Clear dependency separation - CLI deps (clap, tokio, tower-lsp) stay here

Modules

• cli - Main CLI entry point with clap
• repl - Interactive REPL with rustyline
• lsp - LSP server with tower-lsp
• project - Project management commands
• fs_provider - Filesystem implementations of core traits
• engine - Build/compile utilities
• io - R execution utilities
• metaprogramming - Module expansion
