Usage

You MUST print anything in the end of the called command, else it will freeze the process. The session automatically queues commands if it is busy when receiving it.

Importing the Library

import { PipeSession } from 'potpiper';

Initializing a Session

To start a session, you can create an instance of PipeSession:

const session = new PipeSession(execPath, args);

• execPath: The path to the executable.
• args : Arguments.

Sending Commands

You can send commands to the process and receive the results using the send method:

const result = await session.send("your message here");

You can also use the pass method, it ignores all prints, it only returns the last one:

//only the result of "line three" will be returned
const result = await session.pass("line one\n line two\n line three");

Closing the Session

Don't forget to close the session when you're done:

session.close();

Example

Here's a simple example of how to use potpiper with lua:

import { PipeSession } from 'potpiper';

const lua = new PipeSession('luajit');

(async () => {
  const result = await lua.send('your message here');
  console.log(result);
  lua.close();
})();
