pactljson v1.0.1
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.valuein the output ofpactl list modulesis 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,infoandstatAll 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 cardsCode 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);
}
}

// You can also use any of these for more direct pactl access, e.g. in case pactl implements new methods that this library doesn't support yet:
async function _pactlRaw(args=[])
async function _pactlObj(args=[])
async function pactl({server, clientName, args = [] })
