The Derive - API can only report presence, number of occurrences, or values but no indices - or combinations of data. - -### Related Projects - -- [wild](https://crates.io/crates/wild) for supporting wildcards (`*`) on Windows like you do Linux -- [argfile](https://crates.io/crates/argfile) for loading additional arguments from a file (aka response files) -- [shadow-rs](https://crates.io/crates/shadow-rs) for generating `Command::long_version` -- [clap_lex](https://crates.io/crates/clap_lex) for a lighter-weight, battle-tested CLI parser -- [clap_mangen](https://crates.io/crates/clap_mangen) for generating man page source (roff) -- [clap_complete](https://crates.io/crates/clap_complete) for shell completion support -- [clap-verbosity-flag](https://crates.io/crates/clap-verbosity-flag) -- [clap-cargo](https://crates.io/crates/clap-cargo) -- [concolor-clap](https://crates.io/crates/concolor-clap) -- [Command-line Apps for Rust](https://rust-cli.github.io/book/index.html) book -- [`trycmd`](https://crates.io/crates/trycmd): Snapshot testing - - Or for more control, [`assert_cmd`](https://crates.io/crates/assert_cmd) and [`assert_fs`](https://crates.io/crates/assert_fs) - -## Feature Flags - -### Default Features - -* **std**: _Not Currently Used._ Placeholder for supporting `no_std` environments in a backwards compatible manner. -* **color**: Turns on colored error messages. -* **suggestions**: Turns on the `Did you mean '--myoption'?` feature for when users make typos. - -#### Optional features - -* **deprecated**: Guided experience to prepare for next breaking release (at different stages of development, this may become default) -* **derive**: Enables the custom derive (i.e. `#[derive(Parser)]`). Without this you must use one of the other methods of creating a `clap` CLI listed above. -* **cargo**: Turns on macros that read values from `CARGO_*` environment variables. -* **env**: Turns on the usage of environment variables during parsing. -* **regex**: Enables regex validators. -* **unicode**: Turns on support for unicode characters (including emoji) in arguments and help messages. -* **wrap_help**: Turns on the help text wrapping feature, based on the terminal size. - -#### Experimental features - -**Warning:** These may contain breaking changes between minor releases. - -* **unstable-replace**: Enable [`Command::replace`](https://github.com/clap-rs/clap/issues/2836) -* **unstable-grouped**: Enable [`ArgMatches::grouped_values_of`](https://github.com/clap-rs/clap/issues/2924) -* **unstable-v4**: Preview features which will be stable on the v4.0 release +For more details, see: +- [docs.rs](https://docs.rs/clap/latest/clap/) +- [examples](examples/) ## Sponsors -- cgit v1.2.3
