You can create an application with several arguments using usage strings. -//! -//! ```rust -#![doc = include_str!("../examples/tutorial_builder/01_quick.rs")] -//! ``` -//! -#![doc = include_str!("../examples/tutorial_builder/01_quick.md")] -//! -//! ## Configuring the Parser -//! -//! You use [`Command`][crate::Command] to start building a parser. -//! -//! ```rust -#![doc = include_str!("../examples/tutorial_builder/02_apps.rs")] -//! ``` -//! -#![doc = include_str!("../examples/tutorial_builder/02_apps.md")] -//! -//! You can use [`command!()`][crate::command!] to fill these fields in from your `Cargo.toml` -//! file. **This requires the [`cargo` feature flag][crate::_features].** -//! -//! ```rust -#![doc = include_str!("../examples/tutorial_builder/02_crate.rs")] -//! ``` -#![doc = include_str!("../examples/tutorial_builder/02_crate.md")] -//! -//!

You can have users specify values by their position on the command-line: -//! -//! ```rust -#![doc = include_str!("../examples/tutorial_builder/03_03_positional.rs")] -//! ``` -#![doc = include_str!("../examples/tutorial_builder/03_03_positional.md")] -//! -//! ### Options -//! -//! You can name your arguments with a flag: -//! - Order doesn't matter -//! - They can be optional -//! - Intent is clearer -//! -//! ```rust -#![doc = include_str!("../examples/tutorial_builder/03_02_option.rs")] -//! ``` -#![doc = include_str!("../examples/tutorial_builder/03_02_option.md")] -//! -//! ### Flags -//! -//! Flags can also be switches that can be on/off: -//! -//! ```rust -#![doc = include_str!("../examples/tutorial_builder/03_01_flag_bool.rs")] -//! ``` -#![doc = include_str!("../examples/tutorial_builder/03_01_flag_bool.md")] -//! -//! Or counted. -//! -//! ```rust -#![doc = include_str!("../examples/tutorial_builder/03_01_flag_count.rs")] -//! ``` -#![doc = include_str!("../examples/tutorial_builder/03_01_flag_count.md")] -//! -//! ### Subcommands -//! -//! Subcommands are defined as [`Command`][crate::Command]s that get added via -//! [`Command::subcommand`][crate::Command::subcommand]. Each instance of a Subcommand can have its -//! own version, author(s), Args, and even its own subcommands. -//! -//! ```rust -#![doc = include_str!("../examples/tutorial_builder/03_04_subcommands.rs")] -//! ``` -#![doc = include_str!("../examples/tutorial_builder/03_04_subcommands.md")] -//! -//! ### Defaults -//! -//! We've previously showed that arguments can be [`required`][crate::Arg::required] or optional. -//! When optional, you work with a `Option` and can `unwrap_or`. Alternatively, you can set -//! [`Arg::default_value`][crate::Arg::default_value]. -//! -//! ```rust -#![doc = include_str!("../examples/tutorial_builder/03_05_default_values.rs")] -//! ``` -#![doc = include_str!("../examples/tutorial_builder/03_05_default_values.md")] -//! -//! ## Validation -//! -//! ### Enumerated values -//! -//! If you have arguments of specific values you want to test for, you can use the -//! [`PossibleValuesParser`][crate::builder::PossibleValuesParser] or [`Arg::value_parser(["val1", -//! ...])`][crate::Arg::value_parser] for short. -//! -//! This allows you specify the valid values for that argument. If the user does not use one of -//! those specific values, they will receive a graceful exit with error message informing them -//! of the mistake, and what the possible valid values are -//! -//! ```rust -#![doc = include_str!("../examples/tutorial_builder/04_01_possible.rs")] -//! ``` -#![doc = include_str!("../examples/tutorial_builder/04_01_possible.md")] -//! -//! When enabling the [`derive` feature][crate::_features], you can use -//! [`ValueEnum`][crate::ValueEnum] to take care of the boiler plate for you, giving the same -//! results. -//! -//! ```rust -#![doc = include_str!("../examples/tutorial_builder/04_01_enum.rs")] -//! ``` -#![doc = include_str!("../examples/tutorial_builder/04_01_enum.md")] -//! -//! ### Validated values -//! -//! More generally, you can validate and parse into any data type. -//! -//! ```rust -#![doc = include_str!("../examples/tutorial_builder/04_02_parse.rs")] -//! ``` -#![doc = include_str!("../examples/tutorial_builder/04_02_parse.md")] -//! -//! A custom parser can be used to improve the error messages or provide additional validation: -//! -//! ```rust -#![doc = include_str!("../examples/tutorial_builder/04_02_validate.rs")] -//! ``` -#![doc = include_str!("../examples/tutorial_builder/04_02_validate.md")] -//! -//! ### Argument Relations -//! -//! You can declare dependencies or conflicts between [`Arg`][crate::Arg]s or even -//! [`ArgGroup`][crate::ArgGroup]s. -//! -//! [`ArgGroup`][crate::ArgGroup]s make it easier to declare relations instead of having to list -//! each individually, or when you want a rule to apply "any but not all" arguments. -//! -//! Perhaps the most common use of [`ArgGroup`][crate::ArgGroup]s is to require one and *only* one -//! argument to be present out of a given set. Imagine that you had multiple arguments, and you -//! want one of them to be required, but making all of them required isn't feasible because perhaps -//! they conflict with each other. -//! -//! ```rust -#![doc = include_str!("../examples/tutorial_builder/04_03_relations.rs")] -//! ``` -#![doc = include_str!("../examples/tutorial_builder/04_03_relations.md")] -//! -//! ### Custom Validation -//! -//! As a last resort, you can create custom errors with the basics of clap's formatting. -//! -//! ```rust -#![doc = include_str!("../examples/tutorial_builder/04_04_custom.rs")] -//! ``` -#![doc = include_str!("../examples/tutorial_builder/04_04_custom.md")] -//! -//! ## Testing -//! -//! clap reports most development errors as `debug_assert!`s. Rather than checking every -//! subcommand, you should have a test that calls -//! [`Command::debug_assert`][crate::App::debug_assert]: -//! ```rust,no_run -#![doc = include_str!("../examples/tutorial_builder/05_01_assert.rs")] -//! ``` -- cgit v1.2.3
