Text diffs in the sandbox
Specifier: @nodetool-ai/sandbox-diff. Import it at the top of the body.
The diff library schedules with setTimeout, and the guest has no timers, so
it cannot be compiled in. This pack is a host module: the import resolves to
a generated facade over NodeTool's own implementation.
unified — a unified diff of two texts
import { unified } from "@nodetool-ai/sandbox-diff";
const patch = await unified(inputs.before, inputs.after, {
oldName: "before.md",
newName: "after.md",
context: 5
});
return { patch, changed: patch.includes("@@") };
Options: context (lines of context, 0–100, default 3), oldName, newName.
Identical inputs produce a header with no hunks, so includes("@@") is the
cheap "did anything change" test — handy in a verify loop.
Gotchas
unifiedis async.- 5 MB per side. Larger input is refused by name.
- Line-oriented. Two texts that differ only in trailing whitespace still diff; normalize first if that is noise.
