What it is

ripgrep (rg) walks a directory tree and searches every file for a regular expression, skipping hidden, binary and .gitignored files by default. It is one of the fastest grep tools available. In the browser it searches projects loaded into the VM with the same flags developers already know.

With the SDK, installApp resolves ripgrep in the signed index, fetches its content-addressed chunks from the CDN, verifies each one and writes the files into the VM. Details in Installing catalog apps.

javascript

import { createNano } from "@userland-run/nano-sdk";

const nano = await createNano({ image: { wasm: "/nano/console.wasm" }, ramMB: 512 });
await nano.installApp("ripgrep"); // signature-verified, cached in OPFS

const r = await nano.shExec("rg --version");
