Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

LPS CLI Toolset

lps-cli package on npm lps.js Dependencies

LPS is a logic-based programming language and production system developed by Robert Kowalski and Fariba Sadri at Imperial College London. This CLI toolset uses lps.js, the LPS runtime implemented in JavaScript, to enable access to LPS from the command line using Node.js.

This repository contains CLI tools that complement to the usage lps.js on your system. To use lps.js in the browser context or as a Node.js library, see the main repository for instructions.

To access these CLI tools, you must have the Node.js and Node.js Package Manager npm installed on your system. Using npm, you can install LPS CLI Tools as a global package by running:

$ npm install -g lps-cli

Once installed, you will have the following CLI commands available for use:

  • lps: Execute LPS programs
  • lps-generate-spec: Generate a test specification file based on the output from the execution of a LPS program. Executes LPS program.
  • lps-test: Runs a LPS program and compares the output with a test specification file.
  • lps-p2p-tracker: Starts a LPS P2P Peer Tracker service.

To get help for the options and usage of each CLI tool, use the --help option, e.g. lps --help.
