CONSTANTS

const (
	Dir  = "/zx/lib/bib" // default bib dir (should become /u/bib)
	Keys = "ATBSJPRVNEFGICDOWX"
)

TYPES

type Bib struct {
	All []*Ref // once loaded, can be used to iterate over the references.
	// contains filtered or unexported fields
}
    A bib maps from words found in references to references

func Load(dir string) (*Bib, error)
    Load the files at the given dir into a Bib set.

func (b *Bib) Cite(keys ...string) *Ref
    Search bib for keys and return at most one reference

func (b *Bib) Cites(keys ...string) []*Ref
    Search bib for keys and return all matching references

func (b *Bib) WriteTo(w io.Writer)

type Ref struct {
	Keys map[rune][]string
}
    A reference maps from the key (eg. 'A') to values (eg. authors)

func (r *Ref) Authors() string
    return authors separated by "," and terminated with a "."

func (r *Ref) Reference() []string
    Return text lines or sentences for a reference. The strings might be written
    in a single paragraph. The first two strings are usually the title and
    author list, but that depends on the existence of such keys.

func (r *Ref) String() string

func (r *Ref) Title() string
    return title terminated in "."

FUNCTIONS

VARIABLES

var BibTexOk = true
    When true, Load() reads .bib files containing "bib2ref ok" in the first line
    (with this line being discarded). Parsing of the bibtex entries is naive and
    assumes that each field is described in a single line.
