Struct crowbook::Parser

pub struct Parser { /* fields omitted */ }

A parser that reads markdown and convert it to AST (a vector of Tokens)

This AST can then be used by various renderes.

As this Parser uses Pulldown-cmark's one, it should be able to parse most valid CommonMark variant of Markdown.

Compared to other Markdown parser, it might fail more often on invalid code, e.g. footnotes references that are not defined anywhere.

Examples

use crowbook::Parser;
let mut parser = Parser::new();
let result = parser.parse("Some *valid* Markdown[^1]\n\n[^1]: with a valid footnote");
assert!(result.is_ok());

use crowbook::Parser;
let mut parser = Parser::new();
let result = parser.parse("Some footnote pointing to nothing[^1] ");
assert!(result.is_err());

Methods

impl Parser

fn new() -> Parser

Creates a parser

fn from(book: &Book) -> Parser

Creates a parser with options from a book configuration file

fn html_as_text(&mut self, b: bool)

Enable/disable HTML as text

fn set_source_file(&mut self, s: &str)

Sets a parser's source file

fn parse_file<P: AsRef<Path>>(&mut self, filename: P) -> Result<Vec<Token>>

Parse a file and returns an AST or an error

fn parse(&mut self, s: &str) -> Result<Vec<Token>>

Parse a string and returns an AST an Error.

fn parse_inline(&mut self, s: &str) -> Result<Vec<Token>>

Parse an inline string and returns a list of Token.

This function removes the outermost Paragraph in most of the cases, as it is meant to be used for an inline string (e.g. metadata)

fn features(&self) -> Features

Returns the list of features used by this parser
