1**This requires enabling the [`derive` feature flag][crate::_features].** 2 3You can use `--` to escape further arguments. 4 5Let's see what this looks like in the help: 6```console 7$ escaped-positional-derive --help 8A simple to use, efficient, and full-featured Command Line Argument Parser 9 10Usage: escaped-positional-derive[EXE] [OPTIONS] [-- <SLOP>...] 11 12Arguments: 13 [SLOP]... 14 15Options: 16 -f 17 -p <PEAR> 18 -h, --help Print help 19 -V, --version Print version 20 21``` 22 23Here is a baseline without any arguments: 24```console 25$ escaped-positional-derive 26-f used: false 27-p's value: None 28'slops' values: [] 29 30``` 31 32Notice that we can't pass positional arguments before `--`: 33```console 34$ escaped-positional-derive foo bar 35? failed 36error: unexpected argument 'foo' found 37 38Usage: escaped-positional-derive[EXE] [OPTIONS] [-- <SLOP>...] 39 40For more information, try '--help'. 41 42``` 43 44But you can after: 45```console 46$ escaped-positional-derive -f -p=bob -- sloppy slop slop 47-f used: true 48-p's value: Some("bob") 49'slops' values: ["sloppy", "slop", "slop"] 50 51``` 52 53As mentioned, the parser will directly pass everything through: 54```console 55$ escaped-positional-derive -- -f -p=bob sloppy slop slop 56-f used: false 57-p's value: None 58'slops' values: ["-f", "-p=bob", "sloppy", "slop", "slop"] 59 60``` 61
