#tonyfettes/tree_sitter

#Quickstart

1. Add this module as a dependency to your MoonBit project:

   moon update # Update the mooncakes.io package index
   moon add tonyfettes/tree_sitter

2. Import the tonyfettes/tree_sitter package in moon.pkg.json:

   {
     "import": [
       "tonyfettes/tree_sitter"
     ]
   }

3. Optionally you may want to install MoonBit bindings to the tree-sitter grammars you want to use. For example, to install the tree-sitter-moonbit grammar:

   moon add tonyfettes/tree_sitter_moonbit

   And then import the tonyfettes/tree_sitter_moonbit package in your moon.pkg.json file as well:

   {
     "import": [
       "tonyfettes/tree_sitter",
       "tonyfettes/tree_sitter_moonbit"
     ]
   }

4. Use the tonyfettes/tree_sitter API to parse your code:

   fn main {
     let moonbit = @tree_sitter_moonbit.language()
     let parser = @tree_sitter.Parser::new()
     parser.set_language(moonbit)
     let source_code =
       #|fn main {
       #|  println("Hello, World!")
       #|}
     let tree = parser.parse_string(None, source_code)
     let root_node = tree.root_node()
     println(root_node.string())
   }

#API Walkthrough

#Development

#Prerequisites

#Build

# Initialize the tree-sitter submodule
git submodule update --init --recursive
moon update
moon build --target native

python scripts/prepare.py

#Test

cd test && moon test --target native

[!NOTE] You may find that the LSP is not working when you are editing files under the test/ directory. This is because test/ is a MoonBit module itself, and therefore the LSP process has to be spawned in the test/ directory to work properly. In most cases, this means you need to spin up a new editor instance inside the test/ directory.
