Athena is a cross-platform utility for file extension handling across multiple applications with various parameters.

Features

• Cross-platform with portability in mind
  • The commands are as equivalent as possible on all supported platforms
  • Configuration is saved as plain text and can be version-controlled across multiple systems
  • Easily turned portable by creating a user directory in the application's root
• Seamless
  • Double-clicking a file opens an app picker, letting the user choose how to open the file
    • The entries aren't limited to just applications like it is with most system pickers
  • Easily add multiple entries of the same application with different parameters
    • Media player (Play), Media player (Add to queue)
    • Web browser (Open), Web Browser (Open in private window)
  • Multiple app picker frontends are available based on the user's preference
    • TUI (platform-agnostic)
    • WPF (Windows)
    • GTK (Linux)
• Online streaming support
  • For applications that support it, add a protocol prefix to the front of a URL to parse it as a file
    • athena run <URL>/<file>.mp4 (opens in a web browser)
    • athena run athena:<URL>/<file>.mp4 (opens in a video player)
• QoL enhancements
  • Easily edit configuration* and generate templates using built-in commands
