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");

} ```
