§Types of arguments
common types of line options and conventions
This chapter serves as an introduction to available command line options and tries to set the terminology. If you are familiar with command line argument parsers in general - feel free to skip it.
If you ever used any software from a command line (say cargo) you used command line options.
Let’s recap how you might run tests for a crate in your rust project:
$ cargo test -p my_project --verbose
cargo here is an executable name, everything to the right of it separated by spaces are the
options.
Nowadays programs share mostly similar conventions about what a command line argument is, it wasn’t the case before though. Let’s cover the basic types.
- Options, switches or flags
- Option arguments or arguments
- Operands or positional items
- Commands or subcommands
- Exotic schemas
