*Julia bindings for [tree-sitter](https://github.com/tree-sitter/tree-sitter) —

"An incremental parsing system for programming tools."*

[![Build Status](https://travis-ci.org/MichaelHatherly/TreeSitter.jl.svg?branch=1.4)](https://travis-ci.org/MichaelHatherly/TreeSitter.jl)

## Installation

This package is not registered yet and so can be installed using:

```

pkg> add https://github.com/MichaelHatherly/TreeSitter.jl

```

## Usage

```

julia> using TreeSitter

julia> c = Parser(:c)

Parser(Language(:c))

julia> ast = parse(c, "int x;")

(translation_unit (declaration type: (primitive_type) declarator: (identifier)))

julia> json = Parser(:json)

Parser(Language(:json))

julia> ast = parse(json, "{1: [2]}")

(document (object (pair key: (number) value: (array (number)))))

julia> traverse(ast) do node, enter

           if enter

               @show node

           end

       end

node = (document (object (pair key: (number) value: (array (number)))))

node = (object (pair key: (number) value: (array (number))))

node = ("{")

node = (pair key: (number) value: (array (number)))

node = (number)

node = (":")

node = (array (number))

node = ("[")

node = (number)

node = ("]")

node = ("}")

julia> julia = Parser(:julia)

Parser(Language(:julia))

julia> ast = parse(julia, "f(x)")

(source_file (call_expression (identifier) (argument_list (identifier))))

julia> traverse(ast, named_children) do node, enter

           if !enter

               @show node

           end

       end

node = (identifier)

node = (identifier)

node = (argument_list (identifier))

node = (call_expression (identifier) (argument_list (identifier)))

node = (source_file (call_expression (identifier) (argument_list (identifier))))

```
