To derive `clap` types, you need to enable the [`derive` feature flag][crate::_features]. +//! +//! Example: +//! ```rust +#![doc = include_str!("../../examples/demo.rs")] +//! ``` +//! +//! Let's start by breaking down the anatomy of the derive attributes: +//! ```rust +//! use clap::{Parser, Args, Subcommand, ValueEnum}; +//! +//! /// Doc comment +//! #[derive(Parser)] +//! #[command(CMD ATTRIBUTE)] +//! #[group(GROUP ATTRIBUTE)] +//! struct Cli { +//! /// Doc comment +//! #[arg(ARG ATTRIBUTE)] +//! field: UserType, +//! +//! #[arg(value_enum, ARG ATTRIBUTE...)] +//! field: EnumValues, +//! +//! #[command(flatten)] +//! delegate: Struct, +//! +//! #[command(subcommand)] +//! command: Command, +//! } +//! +//! /// Doc comment +//! #[derive(Args)] +//! #[command(PARENT CMD ATTRIBUTE)] +//! #[group(GROUP ATTRIBUTE)] +//! struct Struct { +//! /// Doc comment +//! #[command(ARG ATTRIBUTE)] +//! field: UserType, +//! } +//! +//! /// Doc comment +//! #[derive(Subcommand)] +//! #[command(PARENT CMD ATTRIBUTE)] +//! enum Command { +//! /// Doc comment +//! #[command(CMD ATTRIBUTE)] +//!

Variant1, +//! } +//! +//! fn main() { +//! let cli = Cli::parse(); +//! } +//! ``` +//! +//! Traits: +//! - [`Parser`][crate::Parser] parses arguments into a `struct` (arguments) or `enum` (subcommands). +//! - [`Args`][crate::Args] allows defining a set of re-usable arguments that get merged into their parent container. +//! - [`Subcommand`][crate::Subcommand] defines available subcommands. +//! - Subcommand arguments can be defined in a struct-variant or automatically flattened with a tuple-variant. +//! - [`ValueEnum`][crate::ValueEnum] allows parsing a value directly into an `enum`, erroring on unsupported values. +//! - The derive doesn't work on enums that contain non-unit variants, unless they are skipped +//! +//! *See also the [derive tutorial][crate::_derive::_tutorial] and [cookbook][crate::_cookbook]* +//! +//! ## Attributes +//! +//! ### Terminology +//! +//! **Raw attributes** are forwarded directly to the underlying [`clap` builder][crate::builder]. Any +//! [`Command`][crate::Command], [`Arg`][crate::Arg], or [`PossibleValue`][crate::builder::PossibleValue] method can be used as an attribute. +//! +//! Raw attributes come in two different syntaxes: +//! ```rust,ignore +//! #[arg( +//! global = true, // name = arg form, neat for one-arg methods +//! required_if_eq("out", "file") // name(arg1, arg2, ...) form. +//! )] +//! ``` +//! +//! - `method = arg` can only be used for methods which take only one argument. +//! - `method(arg1, arg2)` can be used with any method. +//! +//! As long as `method_name` is not one of the magical methods it will be +//! translated into a mere method call. +//! +//! **Magic attributes** have post-processing done to them, whether that is +//! - Providing of defaults +//! - Special behavior is triggered off of it +//! +//! Magic attributes are more constrained in the syntax they support, usually just +//! ` = ` though some use `()` instead. See the specific +//! magic attributes documentation for details. This allows users to access the +//! raw behavior of an attribute via `()` syntax. +//! +//! **NOTE:** Some attributes are inferred from [Arg Types](#arg-types) and [Doc +//! Comments](#doc-comments). Explicit attributes take precedence over inferred +//! attributes. +//! +//! ### Command Attributes +//! +//! These correspond to a [`Command`][crate::Command] which is used for both top-level parsers and +//! when defining subcommands. +//! +//! **Raw attributes:** Any [`Command` method][crate::Command] can also be used as an attribute, +//! see [Terminology](#terminology) for syntax. +//! - e.g. `#[command(arg_required_else_help(true))]` would translate to `cmd.arg_required_else_help(true)` +//! +//! **Magic attributes:** +//! - `name = `: [`Command::name`][crate::Command::name] +//! - When not present: [package `name`](https://doc.rust-lang.org/cargo/reference/manifest.html#the-name-field) (if on [`Parser`][crate::Parser] container), variant name (if on [`Subcommand`][crate::Subcommand] variant) +//! - `version [= ]`: [`Command::version`][crate::Command::version] +//! - When not present: no version set +//! - Without ``: defaults to [crate `version`](https://doc.rust-lang.org/cargo/reference/manifest.html#the-version-field) +//! - `author [= ]`: [`Command::author`][crate::Command::author] +//! - When not present: no author set +//! - Without ``: defaults to [crate `authors`](https://doc.rust-lang.org/cargo/reference/manifest.html#the-authors-field) +//! - `about [= ]`: [`Command::about`][crate::Command::about] +//! - When not present: [Doc comment summary](#doc-comments) +//! - Without ``: [crate `description`](https://doc.rust-lang.org/cargo/reference/manifest.html#the-description-field) ([`Parser`][crate::Parser] container) +//! - **TIP:** When a doc comment is also present, you most likely want to add +//! `#[arg(long_about = None)]` to clear the doc comment so only [`about`][crate::Command::about] +//! gets shown with both `-h` and `--help`. +//! - `long_about[ = ]`: [`Command::long_about`][crate::Command::long_about] +//! - When not present: [Doc comment](#doc-comments) if there is a blank line, else nothing +//! - When present without a value: [Doc comment](#doc-comments) +//! - `verbatim_doc_comment`: Minimizes pre-processing when converting doc comments to [`about`][crate::Command::about] / [`long_about`][crate::Command::long_about] +//! - `next_display_order`: [`Command::next_display_order`][crate::Command::next_display_order] +//! - `next_help_heading`: [`Command::next_help_heading`][crate::Command::next_help_heading] +//! - When `flatten`ing [`Args`][crate::Args], this is scoped to just the args in this struct and any struct `flatten`ed into it +//! - `rename_all = `: Override default field / variant name case conversion for [`Command::name`][crate::Command::name] / [`Arg::id`][crate::Arg::id] +//! - When not present: `"kebab-case"` +//! - Available values: `"camelCase"`, `"kebab-case"`, `"PascalCase"`, `"SCREAMING_SNAKE_CASE"`, `"snake_case"`, `"lower"`, `"UPPER"`, `"verbatim"` +//! - `rename_all_env = `: Override default field name case conversion for env variables for [`Arg::env`][crate::Arg::env] +//! - When not present: `"SCREAMING_SNAKE_CASE"` +//! - Available values: `"camelCase"`, `"kebab-case"`, `"PascalCase"`, `"SCREAMING_SNAKE_CASE"`, `"snake_case"`, `"lower"`, `"UPPER"`, `"verbatim"` +//! +//!

In addition, [`.value_parser(value_parser!(T))`][crate::value_parser!] is called for each +//! field. +//! +//! Notes: +//! - For custom type behavior, you can override the implied attributes/settings and/or set additional ones +//! - To force any inferred type (like `Vec`) to be treated as `T`, you can refer to the type +//! by another means, like using `std::vec::Vec` instead of `Vec`. For improving this, see +//! [#4626](https://github.com/clap-rs/clap/issues/4626). +//! - `Option>` will be `None` instead of `vec![]` if no arguments are provided. +//! - This gives the user some flexibility in designing their argument, like with `num_args(0..)` +//! +//! ## Doc Comments +//! +//! In clap, help messages for the whole binary can be specified +//! via [`Command::about`][crate::Command::about] and [`Command::long_about`][crate::Command::long_about] while help messages +//! for individual arguments can be specified via [`Arg::help`][crate::Arg::help] and [`Arg::long_help`][crate::Arg::long_help]. +//! +//! `long_*` variants are used when user calls the program with +//! `--help` and "short" variants are used with `-h` flag. +//! +//! ```rust +//! # use clap::Parser; +//! +//! #[derive(Parser)] +//! #[command(about = "I am a program and I work, just pass `-h`", long_about = None)] +//! struct Foo { +//! #[arg(short, help = "Pass `-h` and you'll see me!")] +//! bar: String, +//! } +//! ``` +//! +//! For convenience, doc comments can be used instead of raw methods +//! (this example works exactly like the one above): +//! +//! ```rust +//! # use clap::Parser; +//! +//! #[derive(Parser)] +//! /// I am a program and I work, just pass `-h` +//! struct Foo { +//! /// Pass `-h` and you'll see me! +//! bar: String, +//! } +//! ``` +//! +//! **NOTE:** Attributes have priority over doc comments! +//! +//! **Top level doc comments always generate `Command::about/long_about` calls!** +//! If you really want to use the `Command::about/long_about` methods (you likely don't), +//! use the `about` / `long_about` attributes to override the calls generated from +//! the doc comment. To clear `long_about`, you can use +//! `#[command(long_about = None)]`. +//! +//! ### Pre-processing +//! +//! ```rust +//! # use clap::Parser; +//! #[derive(Parser)] +//! /// Hi there, I'm Robo! +//! /// +//! /// I like beeping, stumbling, eating your electricity, +//! /// and making records of you singing in a shower. +//! /// Pay up, or I'll upload it to youtube! +//! struct Robo { +//! /// Call my brother SkyNet. +//! /// +//! /// I am artificial superintelligence. I won't rest +//! /// until I'll have destroyed humanity. Enjoy your +//! /// pathetic existence, you mere mortals. +//! #[arg(long, action)] +//! kill_all_humans: bool, +//! } +//! ``` +//! +//! A doc comment consists of three parts: +//! - Short summary +//! - A blank line (whitespace only) +//! - Detailed description, all the rest +//! +//! The summary corresponds with `Command::about` / `Arg::help`. When a blank line is +//! present, the whole doc comment will be passed to `Command::long_about` / +//! `Arg::long_help`. Or in other words, a doc may result in just a `Command::about` / +//! `Arg::help` or `Command::about` / `Arg::help` and `Command::long_about` / +//! `Arg::long_help` +//! +//! In addition, when `verbatim_doc_comment` is not present, `clap` applies some preprocessing, including: +//! +//! - Strip leading and trailing whitespace from every line, if present. +//! +//! - Strip leading and trailing blank lines, if present. +//! +//! - Interpret each group of non-empty lines as a word-wrapped paragraph. +//! +//! We replace newlines within paragraphs with spaces to allow the output +//! to be re-wrapped to the terminal width. +//! +//! - Strip any excess blank lines so that there is exactly one per paragraph break. +//! +//! - If the first paragraph ends in exactly one period, +//! remove the trailing period (i.e. strip trailing periods but not trailing ellipses). +//! +//! Sometimes you don't want this preprocessing to apply, for example the comment contains +//! some ASCII art or markdown tables, you would need to preserve LFs along with +//! blank lines and the leading/trailing whitespace. When you pass use the +//! `verbatim_doc_comment` magic attribute, you preserve +//! them. +//! +//! **Note:** Keep in mind that `verbatim_doc_comment` will *still* +//! - Remove one leading space from each line, even if this attribute is present, +//! to allow for a space between `///` and the content. +//! - Remove leading and trailing blank lines +//! +//! ## Mixing Builder and Derive APIs +//! +//! The builder and derive APIs do not live in isolation. They can work together, which is +//! especially helpful if some arguments can be specified at compile-time while others must be +//! specified at runtime. +//! +//! ### Using derived arguments in a builder application +//! +//! When using the derive API, you can `#[command(flatten)]` a struct deriving `Args` into a struct +//! deriving `Args` or `Parser`. This example shows how you can augment a `Command` instance +//! created using the builder API with `Args` created using the derive API. +//! +//! It uses the [`Args::augment_args`][crate::Args::augment_args] method to add the arguments to +//! the `Command` instance. +//! +//! Crates such as [clap-verbosity-flag](https://github.com/rust-cli/clap-verbosity-flag) provide +//! structs that implement `Args`. Without the technique shown in this example, it would not be +//! possible to use such crates with the builder API. +//! +//! For example: +//! ```rust +#![doc = include_str!("../../examples/derive_ref/augment_args.rs")] +//! ``` +//! +//! ### Using derived subcommands in a builder application +//! +//! When using the derive API, you can use `#[command(subcommand)]` inside the struct to add +//! subcommands. The type of the field is usually an enum that derived `Parser`. However, you can +//! also add the subcommands in that enum to a `Command` instance created with the builder API. +//! +//! It uses the [`Subcommand::augment_subcommands`][crate::Subcommand::augment_subcommands] method +//! to add the subcommands to the `Command` instance. +//! +//! For example: +//! ```rust +#![doc = include_str!("../../examples/derive_ref/augment_subcommands.rs")] +//! ``` +//! +//! ### Adding hand-implemented subcommands to a derived application +//! +//! When using the derive API, you can use `#[command(subcommand)]` inside the struct to add +//! subcommands. The type of the field is usually an enum that derived `Parser`. However, you can +//! also implement the `Subcommand` trait manually on this enum (or any other type) and it can +//! still be used inside the struct created with the derive API. The implementation of the +//! `Subcommand` trait will use the builder API to add the subcommands to the `Command` instance +//! created behind the scenes for you by the derive API. +//! +//! Notice how in the previous example we used +//! [`augment_subcommands`][crate::Subcommand::augment_subcommands] on an enum that derived +//! `Parser`, whereas now we implement +//! [`augment_subcommands`][crate::Subcommand::augment_subcommands] ourselves, but the derive API +//! calls it automatically since we used the `#[command(subcommand)]` attribute. +//! +//! For example: +//! ```rust +#![doc = include_str!("../../examples/derive_ref/hand_subcommand.rs")] +//! ``` +//! +//! ### Flattening hand-implemented args into a derived application +//! +//! When using the derive API, you can use `#[command(flatten)]` inside the struct to add arguments as +//! if they were added directly to the containing struct. The type of the field is usually an +//! struct that derived `Args`. However, you can also implement the `Args` trait manually on this +//! struct (or any other type) and it can still be used inside the struct created with the derive +//! API. The implementation of the `Args` trait will use the builder API to add the arguments to +//! the `Command` instance created behind the scenes for you by the derive API. +//! +//! Notice how in the previous example we used [`augment_args`][crate::Args::augment_args] on the +//! struct that derived `Parser`, whereas now we implement +//! [`augment_args`][crate::Args::augment_args] ourselves, but the derive API calls it +//! automatically since we used the `#[command(flatten)]` attribute. +//! +//! For example: +//! ```rust +#![doc = include_str!("../../examples/derive_ref/flatten_hand_args.rs")] +//! ``` +//! +//! ## Tips +//! +//! - To get access to a [`Command`][crate::Command] call +//! [`CommandFactory::command`][crate::CommandFactory::command] (implemented when deriving +//! [`Parser`][crate::Parser]) +//! - Proactively check for bad [`Command`][crate::Command] configurations by calling +//! [`Command::debug_assert`][crate::Command::debug_assert] in a test +//!

First, let me say that these comparisons are highly subjective, and not meant +//! in a critical or harsh manner. All the argument parsing libraries out there (to +//! include `clap`) have their own strengths and weaknesses. Sometimes it just +//! comes down to personal taste when all other factors are equal. When in doubt, +//! try them all and pick one that you enjoy :). There's plenty of room in the Rust +//! community for multiple implementations! +//! +//! For less detailed but more broad comparisons, see +//! [argparse-benchmarks](https://github.com/rust-cli/argparse-benchmarks-rs). +//! +//! #### How does `clap` compare to [structopt](https://github.com/TeXitoi/structopt)? +//! +//! Simple! `clap` *is* `structopt`. `structopt` started as a derive API built on +//! top of clap v2. With clap v3, we've forked structopt and integrated it +//! directly into clap. structopt is in +//! [maintenance mode](https://github.com/TeXitoi/structopt/issues/516#issuecomment-989566094) +//! with the release of `clap_derive`. +//! +//! The benefits of integrating `structopt` and `clap` are: +//! - Easier cross-linking in documentation +//! - [Documentation parity](../examples) +//! - Tighter design feedback loop, ensuring all new features are designed with +//! derives in mind and easier to change `clap` in response to `structopt` bugs. +//! - Clearer endorsement of `structopt` +//! +//! See also +//! - [`clap` v3 CHANGELOG](https://github.com/clap-rs/clap/blob/v3-master/CHANGELOG.md#300---2021-12-31) +//! - [`structopt` migration guide](https://github.com/clap-rs/clap/blob/v3-master/CHANGELOG.md#migrate-structopt) +//! +//! #### What are some reasons to use `clap`? (The Pitch) +//! +//! `clap` is as fast, and as lightweight as possible while still giving all the features you'd expect from a modern argument parser. In fact, for the amount and type of features `clap` offers it remains about as fast as `getopts`. If you use `clap`, when you just need some simple arguments parsed, you'll find it's a walk in the park. `clap` also makes it possible to represent extremely complex and advanced requirements without too much thought. `clap` aims to be intuitive, easy to use, and fully capable for wide variety use cases and needs. +//! +//! #### What are some reasons *not* to use `clap`? (The Anti Pitch) +//! +//! Depending on the style in which you choose to define the valid arguments, `clap` can be very verbose. `clap` also offers so many finetuning knobs and dials, that learning everything can seem overwhelming. I strive to keep the simple cases simple, but when turning all those custom dials it can get complex. `clap` is also opinionated about parsing. Even though so much can be tweaked and tuned with `clap` (and I'm adding more all the time), there are still certain features which `clap` implements in specific ways that may be contrary to some users' use-cases. +//! +//! #### Reasons to use `clap` +//! +//! * You want all the nice CLI features your users may expect, yet you don't want to implement them all yourself. You'd like to focus on your application, not argument parsing. +//! * In addition to the point above, you don't want to sacrifice performance to get all those nice features. +//! * You have complex requirements/conflicts between your various valid args. +//! * You want to use subcommands (although other libraries also support subcommands, they are not nearly as feature rich as those provided by `clap`). +//! * You want some sort of custom validation built into the argument parsing process, instead of as part of your application (which allows for earlier failures, better error messages, more cohesive experience, etc.). +//! +//! ### How many approaches are there to create a parser? +//! +//! The following APIs are supported: +//! - [Derive][crate::_derive::_tutorial] +//! - [Builder][crate::_tutorial] +//! +//! Previously, we supported: +//! - [YAML](https://github.com/clap-rs/clap/issues/3087) +//! - [docopt](http://docopt.org/)-inspired [usage parser](https://github.com/clap-rs/clap/issues/3086) +//! - [`clap_app!`](https://github.com/clap-rs/clap/issues/2835) +//! +//! There are also experiments with other APIs: +//! - [fncmd](https://github.com/yuhr/fncmd): function attribute +//! - [clap-serde](https://github.com/aobatact/clap-serde): create an `Command` from a deserializer +//! +//! ### When should I use the builder vs derive APIs? +//! +//! Our default answer is to use the [Derive API][crate::_derive::_tutorial]: +//! - Easier to read, write, and modify +//! - Easier to keep the argument declaration and reading of argument in sync +//! - Easier to reuse, e.g. [clap-verbosity-flag](https://crates.io/crates/clap-verbosity-flag) +//! +//! The [Builder API][crate::_tutorial] is a lower-level API that someone might want to use for +//! - Faster compile times if you aren't already using other procedural macros +//! - More flexibility, e.g. you can look up an [arguments values][crate::ArgMatches::get_many], +//! their [ordering with other arguments][crate::ArgMatches::indices_of], and [what set +//! them][crate::ArgMatches::value_source]. The Derive API can only report values and not +//! indices of or other data. +//! +//! You can [interop between Derive and Builder APIs][crate::_derive#mixing-builder-and-derive-apis]. +//! +//! ### Why is there a default subcommand of help? +//! +//! There is only a default subcommand of `help` when other subcommands have been defined manually. So it's opt-in(ish), being that you only get a `help` subcommand if you're actually using subcommands. +//! +//! Also, if the user defined a `help` subcommand themselves, the auto-generated one wouldn't be added (meaning it's only generated if the user hasn't defined one themselves). +//! diff --git a/vendor/clap/src/_features.rs b/vendor/clap/src/_features.rs new file mode 100644 index 0000000..b47ee25 --- /dev/null +++ b/vendor/clap/src/_features.rs @@ -0,0 +1,28 @@ +//! ## Documentation: Feature Flags +//! +//!
