A feature complete *BibTeX* parser using [nom](https://github.com/rust-bakery/nom).

**nom-bibtex** can parse the four differents types of entries listed in the
[BibTeX format description](http://www.bibtex.org/Format/):

- Preambles which allows to call *LaTeX* command inside your *BibTeX*.
- Strings which defines abbreviations in a key-value format.
- Comments.
- Bibliography entries.

## Example

```rust
extern crate nom_bibtex;
use nom_bibtex::*;

const BIBFILE_DATA: &str = r#"@preamble{
        "A bibtex preamble"
    }

    @Comment{
        Here is a comment.
    }

    Another comment!

    @string ( name= "Charles Vandevoorde")
    @string (github = "https://github.com/charlesvdv")

    @misc {my_citation_key,
        author= name,
        title = "nom-bibtex",
        note = "Github: " # github
    }
"#;

fn main() {
    let bibtex = Bibtex::parse(BIBFILE_DATA).unwrap();

    let preambles = bibtex.preambles();
    assert_eq!(preambles[0], "A bibtex preamble");

    let comments = bibtex.comments();
    assert_eq!(comments[0], "Here is a comment.");
    assert_eq!(comments[1], "Another comment!");

    let variables = bibtex.variables();
    assert_eq!(variables["name"], "Charles Vandevoorde");
    assert_eq!(variables["github"], "https://github.com/charlesvdv");

    let biblio = &bibtex.bibliographies()[0];
    assert_eq!(biblio.entry_type(), "misc");
    assert_eq!(biblio.citation_key(), "my_citation_key");

    let bib_tags = biblio.tags();
    assert_eq!(bib_tags["author"], "Charles Vandevoorde");
    assert_eq!(bib_tags["title"], "nom-bibtex");
    assert_eq!(bib_tags["note"], "Github: https://github.com/charlesvdv");
}
