xrepl/protocol

Complete wire protocol implementation for xREPL - 83 operations across 12 modules with 100% spec coverage

Status

✅ Production Ready - All 83 operations from the unified xREPL specification are implemented with 776 comprehensive tests.

Overview

This library provides a complete implementation of the xREPL protocol:

• 83 operations across 12 organized modules
• MessagePack encoding/decoding with length framing
• Request/response builders for all operations
• Comprehensive message validation
• Field aliasing for client compatibility (Emacs, VSCode, etc.)
• Full error handling and standardization

Protocol Operations

The protocol is organized into 12 modules covering:

• Session Management - Session lifecycle and state
• Code Evaluation - Execution and file loading
• System & Introspection - Server capabilities and health
• Code Intelligence - Completion, signatures, formatting
• Navigation - Symbol lookup and definitions
• Documentation - Doc access and generation
• Debugging - Breakpoints, stepping, inspection
• Testing - Test execution and coverage
• Refactoring - Symbol rename, function extraction
• Compilation - Building and static analysis
• BEAM Operations - Hot reload, process inspection
• Advanced Features - Macros, profiling, LSP integration

Installation

Add to your rebar.config:

{deps, [
    {xrepl_protocol, "0.2.0"}
]}.

Usage

;; Encoding an eval request
(let ((request (xrepl-ptcl-ops-eval:eval-request #m(code "(+ 1 2)"))))
  (xrepl-ptcl-msgpack:encode request))

;; Decoding a response
(case (xrepl-ptcl-msgpack:decode binary-data)
  (`#(ok ,message)
   (xrepl-ptcl-ops-eval:parse-response 'eval message)))

Testing

Run the full test suite:
