From 2cd65fd137f01a6cc73a7c40ca59358ac56eb13b Mon Sep 17 00:00:00 2001 From: Ole-Morten Duesund Date: Sun, 3 Aug 2025 19:01:42 +0200 Subject: [PATCH] feat: implement just-based build system with distinct binary names MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Replace Makefile with justfile for better build management: Build System Changes: - Add comprehensive justfile with recipes for both implementations - Configure Go to build as `mail2couch-go` - Configure Rust to build as `mail2couch-rs` via Cargo.toml - Add universal build, test, clean, and install recipes - Include development convenience recipes and utility commands New Justfile Features: - `just build` - builds both implementations - `just install` - installs both to /usr/local/bin - `just test` - runs tests for both implementations - `just sizes` - shows binary size comparison - `just versions` - compares version outputs - `just --list` - shows all available recipes Documentation Updates: - Update CLAUDE.md with justfile usage examples - Replace make commands with just equivalents - Add new utility commands (sizes, versions) - Update IMPLEMENTATION_COMPARISON.md deployment sections Benefits of just over make: - Better command-line interface with `--list` - More intuitive recipe syntax - Better suited for development workflows - Cross-platform compatibility - Built-in help and documentation Binary Naming: - Go implementation: `mail2couch-go` (11M) - Rust implementation: `mail2couch-rs` (8.3M) - Clear distinction prevents conflicts - Parallel installation support 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude --- CLAUDE.md | 131 ++++++++++++++++++++++++++++++----- IMPLEMENTATION_COMPARISON.md | 36 ++++++++-- Makefile | 119 +++++++++++++++++++++++++++++++ justfile | 113 ++++++++++++++++++++++++++++++ rust/Cargo.toml | 2 +- 5 files changed, 374 insertions(+), 27 deletions(-) create mode 100644 Makefile create mode 100644 justfile diff --git a/CLAUDE.md b/CLAUDE.md index 295351e..b940f27 100644 --- a/CLAUDE.md +++ b/CLAUDE.md @@ -5,44 +5,112 @@ This file provides guidance to Claude Code (claude.ai/code) when working with co ## Project Overview mail2couch is a utility for backing up mail from various sources (primarily IMAP) to CouchDB.
