@oh-my-pi/pi-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 "@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",
});

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

Building

# Build native addon from workspace root (requires Rust)
bun run build

# Type check
bun run check

Architecture

@oh-my-pi/pi-natives publishes a small core package plus generated platform-specific optional dependency packages:

crates/pi-natives/       # Rust source (workspace member)
  src/lib.rs             # N-API exports
  src/sixel.rs           # SIXEL terminal-image encoding
  Cargo.toml             # Rust dependencies
native/                  # Core loader files and local/CI native build outputs
  index.js               # Public native export surface
  loader-state.js        # Platform, ISA variant, and addon resolution
  embedded-addon.js      # Standalone binary embed stub/generated metadata
  pi_natives.<platform>-<arch>-modern.node   # x64 modern ISA (local/CI artifact)
  pi_natives.<platform>-<arch>-baseline.node # x64 baseline ISA (local/CI artifact)
  pi_natives.<platform>-<arch>.node          # non-x64 build artifact
npm/<platform>-<arch>/   # Generated at publish time, not committed
  package.json           # @oh-my-pi/pi-natives-<platform>-<arch>
  *.node                 # Only that platform's addon binary or x64 ISA variants
src/                     # TypeScript wrappers and generated declarations source
  native.ts
  index.ts

The published core package contains only the JS loader, declarations, README, and package.json. Release publishing generates one leaf package per supported os/cpu pair and injects those leaves into the core manifest as pinned optionalDependencies, so package managers install only the host platform's native addon. x64 leaves include every built ISA variant, and the loader keeps choosing between baseline and modern at runtime.
