GPM

So you want to make your own package manager?

For something that feels like overkill to create standalone package manager, but is just too lazy to manually check for updates and download.

Introduction

gpm is a lightweight command runner and configuration manager that centralizes the information required to execute scripts across custom-defined package types. It simplifies managing reusable scripts, repositories, and execution environments in a structured and extensible way.

By default, gpm organizes your environment with the following directory layout:

.gpm
├── config.toml     - Stores global repository configuration
├── types.toml      - Defines available package types and their shell arguments
├── repositories    - Managed repositories and package data
│   └── dir
│       ├── .editorconfig
│       ├── FUNDING.yml
│       ├── LICENSE
│       ├── Localizing.md
│       ├── template.typ
│       ├── version.toml    - Contains metadata and script arguments
│       └── ISSUE_TEMPLATE
└── scripts         - Script for all types defined in types.toml
    ├── dir.ps1
    ├── exe.ps1
    ├── file.ps1
    ├── README.md
    ├── zip_exe.ps1
    └── lib
        └── gh_dl.ps1

Core Concept

• Repository - A folder that stores packages
• Package type - Defines how the package is handled handled by the script with the same name.

Features

Download third party cargo subcommand instead of compile locally

1. Add a new repository gpm add cargo --path ~/.cargo/bin

Windows

There's no standard way to pass arguments to executables in Windows, each executable has its own parsing logic. So, if you have issues with passing arguments to certain executables, please open an issue.
