Powering the Web with Logic-based AI

Installing via npm

Install lps.js for your server-side JS app via Node.js package manager (npm) by running the command:

$ npm install lps --save

Then in your code, require() lps.js and run a program file "program.lps" like this :

const LPS = require('lps');
LPS.loadFile('program.lps')
  .then((engine) => {
      engine.run();
  });

Alternatively, a LPS program can also be loaded from string:

const LPS = require('lps');
LPS.loadString('...')
  .then((engine) => {
      engine.run();
  });

Running as CLI

Use the CLI Toolset to run LPS programs from the CLI:

$ npm install -g lps-cli

To run a LPS program file "program.lps", run:

$ lps program.lps

• lps
• lps-test
• lps-generate-spec
• lps-p2p-tracker

For more information and help usage about the CLI Toolset, use the '-v' argument option for each of the available programs.

Using for Frontend

Download the lps.js release bundled for browsers from the Releases page.

Then, use the bundled file through the <script> tag:

<script src="lps.bundle.js"></script>

The LPS API is available through the global variable LPS:

LPS.loadFile('program.lps')
  .then((engine) => {
      engine.run();
  });

Alternatively, a LPS program can also be loaded from string:

LPS.loadString('...')
  .then((engine) => {
      engine.run();
  });
