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

Command	Opened/Generated file	Detection method
`athena edit`	the main configuration file	no additional arguments after the `edit` subcommand
`athena edit mpv.play`	the `mpv player` app entry	an argument after the `edit` subcommand
`athena edit .mp4`	the `.mp4` file extension	the `.` at the start of the file extension
`athena edit https://`	the `https` protocol	the `://` part at the end of the protocol

* due to CliWrap's current limitation, TUI applications opened through Athena don't support interactivity
