Tools

parse_semver

Parse a semantic-version string into major/minor/patch/prerelease/build (keyless, offline). Accepts an optional leading "v".

No parameters required.

▶ Try it
compare_semver

Compare two semver strings. Returns -1 (a<b), 0 (equal), or 1 (a>b), honoring prerelease precedence.

No parameters required.

▶ Try it
satisfies_range

Test whether a version satisfies a range: exact, ^ (caret), ~ (tilde), comparators (>=,>,<=,<,=), x-ranges (1.2.x), AND (space-separated), OR (||). E.g. version "1.4.2", range "^1.2.0".

No parameters required.

▶ Try it

Test with curl

The gateway speaks JSON-RPC 2.0 over HTTP POST. You can test any pack directly from the terminal.

Use with the SDK

Install @pipeworx/sdk to call tools from any TypeScript/Node project.

TypeScript 
import { Pipeworx } from '@pipeworx/sdk';
const px = new Pipeworx();
const result = await px.call("parse_semver", {});
ask_pipeworx 
// Or ask in plain English:
const answer = await px.ask("parse, compare, and range-test semantic versions offline (keyless): prerelease precedence + ^, ~, comparators, x-ranges, and/or ranges");
