hterm on android and mobile devices?

[Will McGugan]

Hi,

I'd love to get hterm working with keyboard input on android / OSX, but tapping on the terminal doesn't bring up the keyboard.

Should I expect the software keyboard to work, or is that just not supported?

Thanks in advance,

Will McGugan

what version are you using ?  the latest releases should pop up the virtual keyboard (or at least, they did last time i tested on my phone/tablet).

I re-built the latest from git. Still no luck with the virtual keyboard.

Does it work for you with latest?

just tried 1.69 and master and i get a virtual keyboard in my android/chrome browser

That's encouraging! Thanks.

Any suggestions how I may have broken the virtual keyboard? Our app is a fairly straight-forward embedded hterm.

https://hterm.org/ has a very simple integration that works for me you can compare against.  it's how i test things.

It's tough to use that integration to try/test anything given the following meta tag :-/

sure, but since Will is a hacker, i'm sure he can grab the index.html and resources and test things locally :)

So I can confirm with the code on hterm.org that the virtual keyboard does work. I'm guessing it must be some other JS on the page that breaks it. Or maybe CSS?

I can probably figure out what broke it by striping out code until it works.

I've gotten a little further in to debugging this one. Even after stripping away all but essential code the problem persists. When I inspect the hterm iframe the only difference is that the <x-screen> tag in our app is lacking a "contenteditable" attribute. If I patch that in, the virtual keyboard works.

I don't see anything in our code that might change that. Virtually all thats left is JQuery. Still debugging, but if anyone has any suggestions, please let me know!

[Mike Frysinger]

correct, in order for the VK to show up, the x-screen element has to be contenteditable.  are you not using hterm to initialize things ?  it takes care of setting those attributes on the x-screen element.

I may have been working with an old version of hterm_all.js, although I could have sworn I re-built and copied it!

After re-building the latest htrem_all the keyboard does come up. But its not quite working in our app. After every keypress I get the following message in console.log:

    No definition for keyCode: 229

The keys appear, but don't invoke "onVTKeystroke". When I hit return, onVTKeystroke is called, but only with a newline character.

In case its relevant, the app I'm working on is essential a remote terminal (https://www.dataplicity.com). Any guidance would be appreciated. I'm a little stuck.

i don't have a Pi, so not sure i can test

to confirm, you're talking about the VK only right ?  if you use a normal keyboard, it works fine ?  VK support is probably alpha level atm ... we've done some basic tests, but i rarely use it, so rely on people to verify it :).

[Will McGugan]

Yeah, just the virtual keyboard. Plugging an external keyboard in to a mobile device seems to work.

No problem if the support is not there yet. We do have a mobile app we can direct users to, VK on mobile would have been a nice-to-have.

If you do more work on VK, I'd be more than happy to test it out. Thanks for the help.

[Mike Frysinger]

honestly, i don't have any immediate plans to do more VK work until it starts impacting people significantly on the CrOS side.  sorry.

VK does work on Android but I can confirm it is not working on iOS.
p.s. I am using chrome on both devices.
