rtreesitter provides R bindings to the [tree-sitter](https://tree-sitter.github.io/tree-sitter/) parsing library.

## Installation

You can install the development version from [GitHub](https://github.com/) with:

``` r

# install.packages("remotes")

remotes::install_github("jimhester/rtreesitter")

```

## Usage

```bash

mkdir vendor

cd vendor

git clone https://github.com/jimhester/tree-sitter-r

git clone https://github.com/tree-sitter/tree-sitter-python

git clone https://github.com/tree-sitter/tree-sitter-javascript

git clone https://github.com/tree-sitter/tree-sitter-go

```

```{r}

library(rtreesitter)

lib_dir <- file.path(tempdir(), "rtreesitter")

lib <- file.path(lib_dir, "languages.so")

repos <- c(

  "tree-sitter/tree-sitter-python",

  "tree-sitter/tree-sitter-javascript",

  "jimhester/tree-sitter-r"

)

for (repo in repos) {

  processx::run("git", c("clone", "--depth=1", sprintf("https://github.com/%s", repo), file.path(lib_dir, basename(repo))))

}

build_library(lib, file.path(lib_dir, basename(repos)))

p_r <- rts_parser$new("tree_sitter_R")

p_r$parse("x <- function(x) 1")

p_py <- rts_parser$new("tree_sitter_python")

p_py$parse("

def foo():

    if bar:

       baz()

")

p_js <- rts_parser$new("tree_sitter_javascript")

p_js$parse('

    let name = "world";

    alert("hello " + name);')

```
