Well...... there is one maybe-sort-of-viable path to a low-quality,
"shovelware" direct port to something that would run on a phone.
Qt for WebAssembly is a thing that exists, and would theoretically let it
run in a browser or, say, an Electron app.Not all of Qt is supported, and I
haven't had a proper look to see if enough of what Hydrogen uses is
supported to make it at all viable, but conspicuously missing are top-level
windows (of course, because it's a browser) and I have no idea if sound is
even supported (Qt has its own audio API which we'd need to target a driver
to, it uses the regular Qt messaging system and is, I think,
single-threaded!).
Either way, Phil is entirely right -- the GUI isn't at all well suited to
mobile and making it usable would need a near-complete overhaul.
HOWEVER!
If you're prepared to live with an absolutely awful user experience, you
can run Hydrogen on an Android device already right now if you want to:
- Install XServer XSDL and start it up
- Install UserLand
- Create an Ubuntu session
- apt install hydrogen
- export PULSEAUDIO_SERVER=tcp:127.0.0.1:<whatever port XSDL tells you
to use>
- start hydrogen and select PulseAudio driver
The user experience is absolutely abysmal, of course, but.... it exists at
least.
