pactljson

1.0.1 • Public • Published

Description

This is a wrapper cli and library for pactl. It's main purpose is to provide a reasonable JSON output format.

Known issues

  • module.value in the output of pactl list modules is kept as a string because I had no good idea for a JSON representation:
    module.value: "[nice.level=<priority: default 20(don't change)>] [rt.prio=<priority: default 88>] [rt.time.soft=<in usec: default -1] [rt.time.hard=<in usec: default -1]"
    
  • I have only tested list, info and stat All the other methods are implemented and probably work, but the output might not be formatted in a way that makes sense For list I have verified all possible types: modules, sinks, sources, sink-inputs, source-outputs, clients, samples, cards, message-handler

CLI usage exapmles

Install via npm i -g pactljson, then use it exactly like pactl. E.g. to get all sound cards in JSON format:

pactljson list cards

Code usage Examples

import { info } from 'pactljson';

async function main() {
    const infoObj = await info();
    const infoJson = JSON.stringify(infoObj, null, '  ');
    console.log(infoJson);
}

main().catch(console.error);
import { list } from 'pactljson';

async function main() {
    const sourcesObj = await list({type: 'sources'});
    const sourcesJson = JSON.stringify(sourcesObj, null, '  ');
    console.log(sourcesJson);

    const cardsObj = await list({type: 'cards'});
    const cardsJson = JSON.stringify(cardsObj, null, '  ');
    console.log(cardsJson);
}

main().catch(console.error);
import { setCardProfile } from 'pactljson';

async function main() {
    try {
        await setCardProfile({card: 1, profile: 'output:analog-stereo'});
        console.log('Card profile set successfully');
    } catch (e) {
        console.error(e);
    }
}

main().catch(console.error);

async function _pactlRaw(args=[])
async function _pactlObj(args=[])
async function pactl({server, clientName, args = [] })
function rawPactlToObj(rawPactlOutput)
