@gajae-code/natives

Native Rust functionality via N-API.

What's Inside

• Grep: Regex-based search powered by ripgrep's engine with native file walking and matching
• Find: Glob-based file/directory discovery with gitignore support (pure TypeScript via globPaths)
• SIXEL: Terminal image encoding for SIXEL-capable terminals (decode, resize, encode in one pass)

General-purpose image processing (decode/resize/encode for files and buffers) lives in Bun.Image on the JS side; this crate only ships the SIXEL encoder because no built-in equivalent exists for that terminal protocol.

Usage

import { grep, find, encodeSixel } from "@gajae-code/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",
});

// SIXEL encode for a terminal cell box (px)
const sequence = encodeSixel(pngBytes, widthPx, heightPx);
