avm

(Potentially) Any language Version Manager, a Command-Line Interface tool designed to manage multiple versions of development tools for potentially any programming language, maximizing code reuse.

Key designs

• Version Management: Easily install, manage, and switch between different versions of various development tools.
• Flexible Installation:
  • Configure mirrors using URL prefix replacement to adapt to different network environments.
  • Install tools from local archives for offline use. Use get-downinfo to get download details and install-local with the downloaded files and info for offline installation.
• Tagging and Aliasing:
  • Each tool version/architecture is identified by a unique tag.
  • Create aliases for tags, providing fixed paths that can point to different underlying tool versions. This is useful for configuring your environment.
  • copy a tag to duplicate its contents, ideal for tools that modify themselves during execution.
• Manual Environment Setup: avm does not automatically modify your system's environment variables. Use the path subcommand to retrieve the installation path for a specific tag or alias and manually configure your environment. Aliases provide stable paths that can point to different underlying tags.

Roadmap

• Liberica JDK/JRE
• Go
• Node.js
• Python
• .NET
  • .NET CLI has its own SDKs manager. Need to decide how to integrate it.
• Rustup
  • Rustup delegate
  • Install rustup if not found
  • Install MSVC toolchain on Windows if not found
• uv for Python
  • uv delegate
  • Install uv if not found

Configuration

The configuration file path can be found by running avm config-path.

Format:

mirror: # optional: Define download mirrors
  - from: https://original-prefix.com/a/b
    to: https://mirror-prefix.com/c/d # e.g., https://original-prefix.com/a/b/e/f becomes https://mirror-prefix.com/c/d/e/f
  # - ... more mirror rules
dataPath: /path/to/data # Optional: Directory to store downloaded tools. Uses an OS-specific default if omitted.
rustup:
  path: /path/to/rustup # Optional: Path to rustup executable.
