@oh-my-pi/pi-natives

Native Rust functionality compiled to WebAssembly via wasm-bindgen.

What's Inside

  • Grep: Regex-based search powered by ripgrep's engine (WASM handles matching, JS handles I/O + gitignore-aware file walking)
  • Find: Glob-based file/directory discovery with gitignore support (pure TypeScript via globPaths)
  • Image: Image processing via photon-rs (resize, format conversion)

Usage

import { grep, find, PhotonImage, resize, SamplingFilter } from "@oh-my-pi/pi-natives";

// Grep for a pattern
const results = await grep({
	pattern: "TODO",
	path: "/path/to/project",
	glob: "*.ts",
	context: 2,
});

// Find files
const files = await find({
	pattern: "*.rs",
	path: "/path/to/project",
	fileType: "file",
});

// Image processing
using image = await PhotonImage.new_from_byteslice(bytes);
using resized = await resize(image, 800, 600, SamplingFilter.Lanczos3);
const pngBytes = await resized.get_bytes();
