Hi everyone,

I made up a small HOWTO and example repository about developing simple enigma2 plugins with visual studio code and docker container.

See it here: https://github.com/t...enigma2_example

Questions and pull requests are welcome!

Hi,
I recently found your instructions on how to run enigma2 plugin with docker and vscode.
I got everything working. But when debugging, the debugger suddenly hangs without any messages. Have you encountered such behavior ever? Sorry for my english.

Hi, I didn't have such errors. However, I am not debugging that often.

 

Does enigma2 also hangs at this moment? Did you inspect all errors from output tab (all outputs) as well as enigma stdout and debugger output tab?

Hi, actually I'm playing with e2iplayer. So when I enter a host, the debugger hangs without any messages. Without the debugger there is no problem. By the way what is the keyboard key for menu?

Menu is space. e2iplayer spawns lots of helper processes from some other binaries, maybe this makes an issue. Try with an example plugin.

First of all, I want to thank you for the neat explanation of setting up Docker with enigma2. That in itself works well. I see that my breakpoint is working with loading. Unfortunately when I click on F4 to select my plugin I get the following stack trace:

Traceback (most recent call last):

    res = self.actions[action]()
  File "/usr/lib/enigma2/python/Screens/InfoBarGenerics.py", line 2193, in showExtensionSelection
    self.session.openWithCallback(self.extensionCallback, ChoiceBox, title=_("Please choose an extension..."), list=list, keys=keys, skin_name="ExtensionsList", reorderConfig="extension_order", windowTitle=_("Extensions menu"))

    return max(max([getListLineTextWidth(line[0][0]) for line in self["list"].list]), textsize)

The terminal process "docker 'exec', '-it', '-e', 'ENIGMA_DEBUG_LVL=5', 'enigma2', '/usr/bin/enigma2', '/opt/mytest-ptvsd.py'" terminated with exit code: 137. 
and a greenscreen of dead..... in VNC.
 
 
my hack for now: 
118                 offset = self["list"].l.getItemSize().height() * count
119                 wsizex = 512 #x_width(textsize[0]) + x_offset() + 10 + scrollbar
120                 #precount description size
121                 descrsize = self["description"].getSize()
122                 self["description"].instance.resize(enigma.eSize(*(wsizex - 20, descrsize[1] if descrsize[1] > 0 else 0)))
123                 # then get true description height
124                 descriptionHeight = 50 #getMaxDescriptionHeight()
125                 wsizey = textsize[1] + offset + descriptionHeight

But I can develop my addon now.... many thnx for that.

@Opvolger. If you want to have plugin under F4 button use the following example code

from Plugins.Plugin import PluginDescriptor
from Screens.MessageBox import MessageBox


def start(session):
    session.open(MessageBox, "Hello World!")


def Plugins(path, **kwargs):
    return [
        PluginDescriptor(name="Example", where=PluginDescriptor.WHERE_EXTENSIONSMENU, fnc=start)
    ]

It's a bug in enigma2 that it crashes when extensions list is empty. Maybe I have to update it.
