go get github.com/steverusso/cli@latest- Lightweight, simple, composable.
- There are zero external dependencies.
- No required project / file layout or recommended use of a generator.
- No reflection.
- Fully POSIX-compliant flags (including short & long versions). (TODO reword and check if true)
- Inputs can additionally be parsed from environment variables and / or default values.
- Nested subcommands.
- Clean, well-formatted help messages by default.
- Ability to build custom help messages.
Note
This is primarily a library to parse command line arguments. Anything it offers in addition to that (such as optionally reading values from environment variables as well) should be invisible to the user who wants to simply parse command line arguments.
