edpm 3.1.24

Easy Dependency Package Manager

edpm

edpm (Easy Dependency Package Manager) is a lightweight tool for managing external dependencies in C++/CMake (and occasionally Python) projects. Unlike heavy package managers (e.g., Spack) or mixed approaches (like CMake’s FetchContent), edpm cleanly separates dependency fetching/building from your main build process—keeping things reproducible and straightforward.

Key Features

• Manifest & Lock File: edpm uses a YAML-based plan (“manifest”) and a lock file to ensure predictable, repeatable installs.
• Minimal Overhead: Installs a known set of scientific/engineering packages without building an entire OS worth of sub-libraries.
• Environment Scripts: Automatically generates shell scripts (bash/csh) so your tools can locate installed packages via PATH, LD_LIBRARY_PATH, and CMAKE_PREFIX_PATH.
• Extensible Recipes: Supports Git + CMake, tarballs, local filesystems, and specialized recipes (e.g., Geant4, ROOT).

Quick Start

1. Install edpm:

   pip install --upgrade edpm
   

2. Initialize & Install:

   # Create or edit your plan (plan.edpm.yaml) then install
   edpm add root geant4
   edpm install
   

3. Use the Environment:

   source <(edpm env)   # or edpm env csh > env.csh
   

   This makes your newly installed packages available to your shell or CMake builds.

Why edpm?

• Avoid “version hell” and heavy-lift solutions like Spack when you only need a few well-defined libraries.
• Keep the build and install steps separate: simpler debugging, faster CI, and more control over dependencies.
• Clean integration with CMake through environment variables or optional CMakePresets.json / EDPMConfig.cmake.

Contributing & Development

• To hack on edpm itself, clone this repository and install in editable mode:

  pip install -e .
  

• We welcome new recipes for scientific libraries, feature requests, and issue reports.
