Description

Breeze JS Bindgen is a command-line tool that generates C++ bindings and TypeScript definitions for Breeze.JS from C++ header files. It uses Clang to parse the C++ code and generates the necessary files to interface C++ code with QuickJS.

Installation

You can install Breeze JS Bindgen globally using Yarn:

yarn global add breeze-bindgen

Or add it as a development dependency to your project:

yarn add --dev breeze-bindgen

Or use it with npx

npx breeze-bindgen

Usage

The breeze-bindgen command-line tool can be used to generate bindings and definitions.

breeze-bindgen -i <input_header_file> [options]

**Options:**

      --version                 Show version number                    [boolean]
  -i, --input                   Path to the input C++ header file to process.
                                                             [string] [required]
  -o, --output                  Directory where the generated binding.h and
                                definition.d.ts files will be saved.    [string]
      --clang                   Optional path to the clang++ executable.[string]
      --cppBindingOutputFile    Name of the generated C++ binding file.
                                             [string] [default: "binding_qjs.h"]
      --tsDefinitionOutputFile  Name of the generated TypeScript definition
                                file.   [string] [default: "binding_types.d.ts"]
      --tsModuleName            Name of the TypeScript module.
                                                  [string] [default: "BreezeJS"]
      --extTypesPath            Path to additional type definitions.
                                                          [string] [default: ""]
      --nameFilter              Clang AST dump filter for names (e.g.,
                                "breeze::js").  [string] [default: "breeze::js"]
  -h, --help                    Show help                              [boolean]

Example:

breeze-bindgen -i ./src/my_module.h -o ./generated

This will generate binding_qjs.h and binding_types.d.ts in the ./generated directory based on the definitions found in ./src/my_module.h that match the default name filter.

Development

• yarn build: Builds the project (CommonJS and ES modules for index and ES module for cli).
• yarn cli: Runs the CLI using esbuild-register.
• yarn typegen: Runs the type generation script using esbuild-register.
• yarn parser-test: Runs the C type parser test script using esbuild-register.
