//! Note: this documentation is relative to `crowbook` *as a library*.
//! For documentation regarding the *program* `crowbook`, see
//! [the Github page](https://github.com/lise-henry/crowbook).
//!
//! # Usage
//!
//! Just like any other library, just add a dependency on `crowbook`
//! in your `Cargo.toml` file. You will probably want to deactivate
//! default features that are mostly useful for the binary:
//!
//! ```ignore
//! crowbook = {version = "0.14.1", default-features = false}
//! ```
//!
//! # Book
//!
//! The central structure of Crowbook is `Book`, which coordinates everything.
//!
//! Its roles are:
//!
//! * read a book configuration file and setting the book options accordingly;
//! * read the chapters (written in Markdown) listed in this
//! configuration file and pass them to to `Parser`, get back an AST and store it in memory
//! * call the various renderers according to the book's parameters
//! and generate the appropriate files.
//!
//! ## Example
//!
//! ```ignore
//! use crowbook::Book;
//! // Reads configuration file "foo.book" and render all formats according to this
//! // configuration file
//! Book::new()
//! .load_file("foo.book").unwrap()
//! .render_all().unwrap();
//! ```
//!
//! This is basically the code for the `crowbook` binary (though it contains a
//! bit more error handling, checking parameters from command line and so on).
//! This is, however, not very interesting for a library usage.
//!
//! The `Book` structure, however, exposes its `chapter` fields, which contains
//! a vector with an element by chapter. With it, you can access the Markdown
//! for all chapters represented as an Abstract Syntax Tree (i.e., a vector of `Token`s).
//! It is thus possible to create a new renderer (or manipulate this AST in other ways).
//!
//! # Parser
//!
//! It is also possible to directly use `Parser` to transform some markdown string or file
//! to this AST:
//!
//! ```
//! use crowbook::{Parser,Token};
//! let mut parser = Parser::new();
//! let result = parser.parse("Some *valid* Markdown").unwrap();
//! assert_eq!(format!("{:?}", result),
//! r#"[Paragraph([Str("Some "), Emphasis([Str("valid")]), Str(" Markdown")])]"#);
//! ```
//!
//! Of course, you probably want to do something else with this AST than display it.
//! Let's assume you want to count the number of links in a document.
//!
//! ```
//! use crowbook::{Parser,Token};
//! fn count(ast: &[Token]) -> u32 {
//! let mut n = 0;
//! for token in ast {
//! match *token {
//! // It's a link, increase counter
//! Token::Link(_,_,_) => n += 1,
//! // It's not a link, let's count the number of links
//! // inside of the inner element (if there is one)
//! _ => {
//! if let Some(sub_ast) = token.inner() {
//! n += count(sub_ast);
//! }
//! }
//! }
//! }
//! n
//! }
//!
//! let md = "# Here's a [link](http://foo.bar) #\n And *another [one](http://foo.bar)* !";
//!
//! let mut parser = Parser::new();
//! let ast = parser.parse(md).unwrap();
//! assert_eq!(count(&ast), 2);
//! ```
