Terminal emulator for Touch (and Paperwhite?)
Hi,
My port of XTerm stopped working with 5.3 firmware. Instead of trying to revive it I took another way. I wrote a very simple GTK+ terminal emulator based on VteTerminal library.
It is available for testing here.
I run it successfully on KT 5.3.2 firmware. I hope it will also work on PW. It is reported to run fine on Paperwhite. I believe it should also be compatible with 5.1 firmware.
Any feedback welcome

Wow, great! Looking forward to a terminal for KT 5.3.2 since the firmware update.

Thanks, I'll give it a try.

Eh, there seems to be a problem: if I quit the kterm by type
Code:
# exit
, the matchbox-keyboard will not terminate, and when I run kterm through ssh again, the input wil be a mess.

The code which launched the matchbox-keyboard is probably missing a trap for sigterm that would allow it to terminate matchbox-keyboard before it exits.

Author can probably fix that without too much trouble.

Thanks for testing it!
I can't reproduce your error. How did you start kterm? You mean that keyboard stays open after terminal is closed?

I ssh into the kindle, and launch kterm by
Code:
# /mnt/us/extensions/kterm/bin/kterm
then I can see kterm running on KT. I run some command such as ls, cd, and it works well.

Then I type exit to quit the kterm.

But if you run ps -e or pgrep -l match in ssh, you may see that matchbox-keyboard is still running in the background.

No, the keyboard doesn't stay open on the screen, but is still running in the background.

Hmm, it should be killed when kterm exits. I tried several times and it did every time.
Does it stay alive each time you exit kterm?
What happens if you quit by choosing "quit" from the menu?

Kung-Fu. Hard work over time to accomplish skill. A painter can have kung-fu... The musician can have kung-fu, or the poet who paints pictures with words and makes emperors weep. This, too, is kung-fu. Formless, nameless, the true master dwells within. Only you can free him.

SIGTERM (15) should be enough. But maybe there is something I don't get.
My matchbox-keyboard is polite to go, silverzhao's is not

Could he have somehow created one more matchbox-keyboard than that in a matchbox-keyboard/xterm pair?

Have him do a Kindle restart, try that again, and this time include the pid and ppid in the posts.

Or kterm died without killing its child.

No need to restart Kindle. I think killall -9 matchbox-keyboard will do.

Ah, I reboot my kindle just, and run the kterm again. Now it seems no problem any more, no more matchbox-keyboard left running in the background when the kterm exits. Maybe it is because of that my kindle has run for too long time before?

Sorry to trouble you about this problem.

But here seems to be another problem: if I want to run kterm the second time, it will sometimes print a lot of newlines, as is shown in the attached picture. Do you have this problem?

Besides, a question: is there anyway to save the font size setting? The default font size is a little larger for me.

Yes, it happens sometimes. I don't know why yet. Same thing happened in kindle port of XTerm.

Unfortunately no. I may add some config in future.

Thanks for feedback!

It's wonderfully clean code. Simple and clear make. not a difficult TC to use neither.

In the interim (before a config-able release was to surface it would be a relatively trivial job to slap together yourself a custom version. : )
