`bcf` is a [bcf](https://samtools.github.io/hts-specs/BCFv2_qref.pdf) parser for the go programming language.

```Go

import "github.com/brentp/bcf"

func main() {

    rdr, _ := os.Open("some.bcf")

    brdr, _ := bcf.NewReader(rdr, 2)

    for {

        variant, err := brdr.Read()

        if err == io.EOF {

            break

        }

        fmt.Println(variant.Chrom, variant.Id, variant.Pos)

    }

}

```

TODO

====

The library is currently working, but some things remain to be done:

+ parse header into proper structure

+ fix parsing of FILTER

+ finalize parsing of FORMAT fields. This is done, but we don't currently replace the missing tokens with NaN or whatever is appropriate.

+ benchmark the current INFO and FORMAT parsing (which is lazy) that saves a slice (3 uint32's) to the underlying data to compare to just saving the offsets and having each entry in the INFO pull from

 the same underlying slice.

+ docs
