A feature complete BibTeX parser using nom.

nom-bibtex can parse the four differents types of entries listed in the BibTeX format description:

• 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 nombibtex; use nombibtex::*;

const BIBFILE_DATA: &str = "@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[0], ("name".into(), "Charles Vandevoorde".into()));
assert_eq!(variables[1], ("github".into(), "https://github.com/charlesvdv".into()));

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[0], ("author".into(), "Charles Vandevoorde".into()));
assert_eq!(bib_tags[1], ("title".into(), "nom-bibtex".into()));
assert_eq!(bib_tags[2], ("note".into(), "Github: https://github.com/charlesvdv".into()));

} ```
