# OPML 📄 # OPML
> **OPML library for Rust & standalone CLI.** > An OPML parser for Rust and the command-line.
## API ## API
For API documentation and examples see [docs.rs](https://docs.rs/opml). For the API documentation, see [docs.rs](https://docs.rs/opml).
## CLI ## CLI
### Cargo To install the OPML command-line parser, run `cargo install opml_cli` or download a precompiled executable directly from [the Releases page](https://github.com/Holllo/opml/releases/latest).
With a working [Rust and Cargo](https://www.rust-lang.org/learn/get-started) installation, you can install the OPML CLI from [Crates.io](https://crates.io/crates/opml_cli). Then run `opml --help` to see all the available options.
```
cargo install opml_cli
```
### Binaries
Precompiled `x86_64-unknown-linux-gnu` binaries are available on the [Releases page](https://git.bauke.xyz/Holllo/opml/releases).
## Development
With [Nix flakes](https://nixos.wiki/wiki/Flakes) and [direnv](https://direnv.net/) installed and enabled, all the required dependencies are automatically loaded from [`shell.nix`](./shell.nix). Then [cargo-make](https://sagiegurari.github.io/cargo-make/) can be used to build, deploy and lint the code. The available tasks are all described in the [`Makefile.toml`](Makefile.toml) configuration.

//! This crate provides an API to parse and create [OPML documents]. //! This crate provides an API to parse and construct
//! [OPML documents](http://dev.opml.org/spec2.html) to and from regular Rust
//! structs.
//! //!
//! [OPML documents]: http://opml.org/spec2.opml //! ## Getting Started
//! //!
//! ## Parsing //! ### Parsing
//! //!
//! To parse an OPML document use [`OPML::from_str`] or [`OPML::from_reader`]. //! Parsing XML into [an OPML struct](struct.OPML.html) can be done with
//! //! [`OPML::new()`](struct.OPML.html#method.new). Resulting in an error if the
//! Parsing will result in an error if: //! XML can't be parsed, if the included OPML version is not supported
//! * the XML is malformed, //! (currently all OPML versions (1.0, 1.1 and 2.0) are supported) or if the
//! * the included OPML version is not supported (currently all OPML versions //! [Body](struct.Body.html) element contains no child
//! (1.0, 1.1 and 2.0) are supported) or, //! [Outline](struct.Outline.html) elements,
//! * if the [`Body`] element contains no child [`Outline`] elements, //! [as per the spec](http://dev.opml.org/spec2.html#whatIsALtbodygt).
//! [as per the spec].
//!
//! [as per the spec]: http://opml.org/spec2.opml#1629042198000
//! //!
//! ```rust //! ```rust
//! use opml::OPML; //! use opml::{OPML, Outline};
//! //!
//! let xml = r#"<opml version="2.0"><head/><body><outline text="Outline"/></body></opml>"#; //! let xml = r#"<opml version="2.0"><head/><body><outline text="Outline"/></body></opml>"#;
//! let document = OPML::from_str(xml).unwrap(); //! let parsed = OPML::new(xml).unwrap();
//! //!
//! assert_eq!(document.version, "2.0"); //! let mut expected = OPML::default();
//! expected.body.outlines.push(Outline {
//! text: "Outline".to_string(),
//! ..Outline::default()
//! });
//!
//! println!("{:#?}", parsed);
//! assert_eq!(parsed, expected);
//! ``` //! ```
//! //!
//! ## Creating //! ### Constructing
//! //!
//! To create an OPML document from scratch, use [`OPML::default()`] or the good //! Constructing OPMLs is very easy as all you have to do is instantiate the
//! old `OPML { /* ... */ }` syntax. //! [OPML struct](struct.OPML.html) with
//! [`OPML::default()`](struct.OPML.html#method.default), add anything wanted
//! and then call [`OPML::to_xml()`](struct.OPML.html#method.to_xml) to return
//! the XML as a string.
//!
//! ```rust
//! use opml::{Head, OPML};
//!
//! let mut opml = OPML::default();
//! opml.head = Some(Head {
//! title: Some("Rust Feeds".to_string()),
//! ..Head::default()
//! });
//! opml
//! .add_feed("Rust Blog", "https://blog.rust-lang.org/feed.xml")
//! .add_feed(
//! "Inside Rust",
