tree-sitter-sql

A general/permissive SQL grammar for tree-sitter.

Installation

We don't commit the generated parser files to the main branch. Instead, you can find them on the gh-pages branch. We're open to feedback & encourage you to open an issue to discuss any problems.

They are also hosted on the GitHub pages site and available for download here: github://derekstride/tree-sitter-sql/gh-pages.tar.gz.

Plugin maintainers ensure to specify the HEAD (or a specific revision) of the gh-pages branch when integrating with this project.

Step 1: Download the parser files

Using git

git clone https://github.com/DerekStride/tree-sitter-sql.git
cd tree-sitter-sql
git checkout gh-pages

Using curl

curl -LO https://github.com/DerekStride/tree-sitter-sql/archive/refs/heads/gh-pages.tar.gz
tar -xzf gh-pages.tar.gz
cd tree-sitter-sql-gh-pages

Step 2: Compile the Parser

Tree-sitter parsers need to be compiled as a shared-object / dynamic-library, you can enable this by passing the -shared & -fPIC flags to your compiler.

cc -shared -fPIC -I./src src/parser.c src/scanner.c -o sql.so

Development

See CONTRIBUTING.md for documentation on how to set up the project for development.
