Hurl tree-sitter Parser

hurl.dev

Introduction

Welcome to the Hurl Tree-sitter parser. This project is aimed at creating a syntax parser for Hurl, a text form of the CURL tool using the Tree-sitter parsing library.

Tree-sitter is a parser generator tool and an incremental parsing library. It aims to build a concrete syntax tree for a source code and efficiently update the syntax tree as your source code changes.

This parser aids in transforming the text representation of Hurl into a structured format that can be utilized by various text editors or IDEs for features like syntax highlighting, code linting, and intelligent code completion.

Dependencies

• Node.js

Installation

1. Clone this repository:

   git clone https://github.com/kjuulh/tree-sitter-hurl.git
   

2. Navigate to the repo:

   cd tree-sitter-hurl
   

3. Install the required dependencies:

   npm install
   

4. Compile the parser:

   npm run ci # runs both generate and test (for good measure)
   

Usage

To parse a file or text, run:

tree-sitter parse examples/<file-name>.hurl

This will generate a syntax tree for the input file.

-- Search for vim.filetype.add
vim.filetype.add({
  extension = {
    hurl = "hurl"
  }
})

Add your own queries and injections as well (will come with nvim-treesitter, if it ever goes upstream)

cp -r queries ~/.config/nvim

Moves queries to your own nvim config. It may be placed somewhere else use :h rfp for help

Testing

Tests can be performed using the following command:

npm run test

All test files are located in the ./corpus directory. If you wish to add more test cases, simply add new .txt files in the corpus directory following the existing naming convention.
