Clara HD (Pre-FBInk) rmkit on my Clara HD

[raisjn]

if input_demo can draw to screen, that is really promising!! now the question is: why did remux not succeed at drawing :-/ the line about "displayed launcher for 400ms" is a little suspicious, but I'm unsure

[elinkser]

That is encouraging news!

Dragging the square - you're right about how that works.

Swiping not killing app - right again, it is killed by clicking on the memory stat listed to the right of the item in the main menu, which you are not seeing.

Drawing_demo and simple not doing much - lol drawing_demo presents a blank page for you to drag your finger around to leave a hazy trail. Simple is really a framework within a framework to support the actual script app which you would click on like menu.sh.

The one other test I could suggest before Raisjn checks in is:
If you put your ereader in Activities mode so that there are no Nickelly elements to respond to touch in the middle of the display, what happens when you click on your invisible remux main window, where the menu elements are supposed to be?

Maybe they are there but invisible....

[elinkser]

oh hi raisjn, didn't see you there!

I'm not sure if this is anything, but unlike Clouds, my very next line after detecting device was "Enabled Kobo Mark 7 quirks".

Maybe NiLuJe could lend some insight?

On a hunch, I tried rmkit in landscape rotation and got the same "NOT SHOWING LAUNCHER IN LANDSCAPE" as Clouds.

So I removed the condition.

$ nano -l src/remux/launcher.cpy

  34 //#define PORTRAIT_ONLY

Now I don't get the message.
Clouds can you try this one please?



***

[raisjn]

wow, good catch! I completely missed that log line - hmmm ������

elinkser: when you removed that define, did remux show in landscape mode?

[elinkser]

***


Yes that's right.

The previous remux (0131) gives repeated "NOT SHOWING LAUNCHER IN LANDSCAPE" log messages when I swipe up in landscape orientation.

The latest remux (0201) displays the launcher menu correctly when I swipe up. (You have to swipe from all the way at the bottom corner, but it did not cause me any nickel item activation.)

Interestingly, the latest input_demo (0131) works while the one I uploaded in Post #1 gives me a double pane.

Conversely, the harmony drawing app uploaded in Post #10 still works great, as does the puzzles collection from Post #28, but the latest harmony seems to not permit drawing with any drawing tool. Rpncalc works, for those who like reverse polish notation calculators.

Killing apps and returning to Nickel worked unless I used the old input_demo.

So, I guess we're waiting on Clouds...
I uploaded rpncalc for an extra incentive!

I see the problem. I'm not sure what the correct capability to check is (look for supports_stylus in input.cpy). I need some indication that there is a stylus on the Elipsa. It looks like other devices also claim to support BTN_TOOL_PEN, though.

[Clouds]

Now I don't get the message.
Clouds can you try this one please?

With remux-0201 I don't get the "NOT SHOWING LAUNCHER IN LANDSCAPE" message either. Unfortunately that's all that's different. Still nothing happens on screen. Output is the same as well (apart from the "landscape" line)

If you put your ereader in Activities mode so that there are no Nickelly elements to respond to touch in the middle of the display, what happens when you click on your invisible remux main window, where the menu elements are supposed to be?

Well....nothing really. Nothing on screen, no output to ssh window. I tried tapping everywhere on the screen just to be sure.

On the positive side of things: rpncalc works fine...

Ok, let's try this:

You can try to get launcher to "show" via second SSH window where you launch command:

# echo 'show' > /run/remux.api

(This info was from src/remux/README.md)

92 ### API (0.1.6)
93
94 remux opens `/run/remux.api` as a FIFO and listens for incoming commands. The supported commands are `show`, `hide`, and `back`.

Let's add a second way to get the launcher to show in remux-0202:

# echo 'show2' > /run/remux.api

Anything displayed?
You may have to do a '# ps' then '# kill -KILL <remux.sh process id> to kill remux.

$ nano -l src/remux/launcher.cpy

 430     if line == "show":
 431       self.show_launcher()
 432     else if line == "show2":
 433       app_dialog->show()

***

(Unrelated) kludge to get wordlet app to compile:

$ nano -l src/wordlet/app/keyboard.cpy

...
119             kev := KeyboardEvent {self.text}
...
130           kev := KeyboardEvent {self.text}
...
159             kev := KeyboardEvent {self.text}
...

Otherwise, same error would occur 3 times e.g.:
/keyboard.h:121:18: error: designated initializers cannot be used with a non-aggregate type 'ui::KeyboardEvent'
121 | auto kev = KeyboardEvent {text:this->text};

[raisjn]

Clouds: i'm waiting on a KA1, should hopefully be here next week

elinkser: you can try fbink branch again (harmony should support drawing properly now (i hope). i tested on elipsa and clara. i'll also go back over this thread and pull in more of your fixes

[elinkser]

Latest harmony tested and drawing working again.
Thanks raisjn!

You can try to get launcher to "show" via second SSH window where you launch command:

# echo 'show' > /run/remux.api

Another step forward!
Running remux-0201, issuing echo 'show' > /run/remux.api in the second ssh window launches the menu! Menu items that refer to programs that would work when launched from cli (such as input_demo, rpncalc) can then be launched from the menu.

After running echo 'show' > /run/remux.api the menu shows and the window running remux says:

Let's add a second way to get the launcher to show in remux-0202:
# echo 'show2' > /run/remux.api

This method works too. However, it appears that when using this method touch input is sent to both the menu, the program that was started from the menyu, and Nickel below it. With the original method to launch the menu touch input is sent only to the menu and app launched from it.
It appears to me that this is because method2 doesn't stop the currently running app.
The lines from method1

SENDING 19 TO GROUP -736 RET 0
SENDING 19 TO GROUP -614 RET 0
stopping apps took 0.0222954

don't appear with method2. Instead, with method2 only this line appears:

SENDING 18 TO GROUP -2725 RET 0

Sometimes, regardless of the method used to spawn the menu, there will be a long (or even endless) loop of

NEW THREAD EXC Resource temporarily unavailable

put out to the window running remux. I haven't been able to find a pattern or cause yet.

Also the screen isn't always (re)drawn completely. E.g. when launching the menu or one of the menu items, only part of the screen is redrawn. Input elements do work at that time even when invisible, and if input actions give reason to redraw (part of) the screen, the program is displayed (more) completely.

I added the echo 'show' > /run/remux.api command as an entry to NickelMenu too. That way to spawn the menu works too.

[elinkser]

Nice job. I'm glad were able to get a nice NickelMenu app out of it.

Now we can relax and wait for raisjn to get an Aura One.

But if you want, we can also continue to plod along at a leisurely pace.
Totally optional of course!

The main difference I see with your output log when swiping up is

DISPLAYED LAUNCHER FOR 358 MS
NOT HIDING LAUNCHER BECAUSE INTERVAL < 500

Could it be that the launcher is actually shown, but then quickly hidden again (before even being rendered to screen) because the swipe up is also interpreted as clicking outside the menu, thus closing it?
