XR pass-through integration #19

Examples of changing screen resolution to make it more readible.


var http = require('http')
var url = require('url')
var fs = require('fs')

const execSync = require('child_process').execSync;

const highrescmd = 'xrandr --output DP-0 --mode 2560x1440; xrandr --output DP-2 --mode 1920x1080'
const lowrescmd = 'xrandr --output DP-2 --mode 800x600; xrandr --output DP-0 --mode 1600x1200'

http.createServer(function (request, response) {
    var requestUrl = url.parse(request.url)
    response.writeHead(200)
    console.log(requestUrl.pathname)
    if (requestUrl.pathname == '/low')
        code = execSync(lowrescmd);
    else
        code = execSync(highrescmd);
    response.end()
}).listen(9615)

Could also provide a list of opened tabs.

Could rely on an eye chart to calibrate scaling per user. Ideally it'd be displayed on the target screens though, not in the XR display controlling scaling. Selected value could then be saved locally, e.g localStorage, or remotely with a user ID so that it becomes the default on next connection.

Consider how furnitures could be used too, via e.g https://immersive-web.github.io/real-world-meshing/ , to know where screens are related to user.

Consider also kwin and Vimperator scripts, among the different ways to manage windows and tabs programmatically and thus remotely.

see also #16 to avoid doing specific documentation and endpoints

paths /hmdlink and /hmdlink/set are arguably XR specific, even though in truth are mostly about devices with inconvenient input methods

example with KWin :

script=/home/fabien/Prototypes/kwin-scripting/minimizeall.kjs
# from https://unix.stackexchange.com/a/517690/486198

num=$(dbus-send --print-reply --dest=org.kde.KWin \
    /Scripting org.kde.kwin.Scripting.loadScript \
    string:"$script" | awk 'END {print $2}' )

dbus-send --print-reply --dest=org.kde.KWin /$num \
    org.kde.kwin.Script.run

# I'm not sure if some delay is in order here to let your script complete?
dbus-send --print-reply --dest=org.kde.KWin /$num \
    org.kde.kwin.Script.stop

running the content of minimizeall.kjs

const clients = workspace.clientList();
for (var i = 0; i < clients.length; i++) {
  print(clients[i].caption);
  clients[i].minimized = true;
}

see past test with xdotool when APIs are missing e.g https://twitter.com/utopiah/status/1499486056042872839 and https://twitter.com/utopiah/status/1493480186368700416

Instead consider JavaScript timer in :jsb running tri.excmds.source("~/path/to/magic/RC") and have your RC file start that timer (cf discussion on Matrix)
