# tree-sitter-newick

A [tree-sitter](https://tree-sitter.github.io/tree-sitter/) grammar for the
[Newick (nh, nwk)](https://en.wikipedia.org/wiki/Newick_format) and [New
Hampshire X
(nhx)](https://www.cs.mcgill.ca/~birch/birchhomedir/java/forester/NHX.pdf)
formats for trees representation.

# Example

## NHX source

```
(
    (
        (
            ADH2:0.1[&&NHX:S=human:E=1.1.1.1],
            ADH1:0.11[&&NHX:S=human:E=1.1.1.1]
        ):0.05[&&NHX:S=Primates:E=1.1.1.1:D=Y:B=100],
        ADHY:0.1[&&NHX:S=nematode:E=1.1.1.1],
        ADHX:0.12[&&NHX:S=insect:E=1.1.1.1]
    ):0.1[&&NHX:S=Metazoa:E=1.1.1.1:D=N],
    (
    ADH4:0.09[&&NHX:S=yeast:E=1.1.1.1],
    ADH3:0.13[&&NHX:S=yeast:E=1.1.1.1],
    ADH2:0.12[&&NHX:S=yeast:E=1.1.1.1],
    ADH1:0.11[&&NHX:S=yeast:E=1.1.1.1]
    ):0.1[&&NHX:S=Fungi]
)[&&NHX:E=1.1.1.1:D=N];
