This article is about How to use the Python extension "Envy" by Cyke64

The envy module is for 3rd Edition devices only.

Envy is mainly used to prevent closing/exiting/aborting the python/application on pressing the red/disconnect key. Also a useful feature is that it prevents Python to be closed in low memory condition too.

Below is the code for the same.

#importing the module envy
import envy
 
#Print version of envy
print envy.version
 
print envy.is_app_system()
try:
  envy.set_app_system(1) # trying to set system your application
                         # (standalone) or python shell if you run it from there !
except: 
  print 'exception !'    #exception encountered
  
print envy.is_app_system() 
#After this code it the pythonshell would not exit
#on pressing the red/disconnect key

An Added update to the envy module has a additional feature. Using it one could check if the python scriptshell is unsigned with dev cert (13) or selfsigned (5 caps) or amazing with any capabilities,

Below is the code for using this added feature.

from envy import *
# testing selfsigned
print has_capabilities(SELFSIGNED) # return 1 if True / 0 if false
print has_capabilities('selfsigned') 
print has_capabilities('ALL-ReadDeviceData-WriteDeviceData-TrustedUI-ProtServ-SwEvent-Location-SurroundingsDD-PowerMgmt-NetworkControl-CommDD-MultimediaDD-DiskAdmin-DRM-TCB-AllFiles') print has_capabilities((ECapabilityReadUserData,ECapabilityWriteUserData,ECapabilityUserEnvironment,ECapabilityNetworkServices,ECapabilityLocalServices)) print has_capabilities('ReadUserData+WriteUserData+UserEnvironment+NetworkServices+LocalServices')
 
# testing unsigned
print has_capabilities('unsigned') 
 
# testing your against any capabilities set
print has_capabilities('ALL-TCB-AllFiles')
 
# Display capacity in Python Script shell or your standalone application if running 
#from this location !
 
print app_capabilities()

Another added update to the envy extension has made possible remove Python Script shell icon or your standalone application icon from task list. Thus the application runs in the background an thus becomes invisible!

Below is the code for making the application/Pythonshell invisible.

importing the module envy
import envy
 
#Print version of envy
print envy.version
 
print envy.is_app_hidden() 
 
try:
  envy.set_app_hidden(1) # try to hide your application from tasklist
                         # (standalone) or python shell if you run it from there !
except: 
  print 'exception !'
  
print envy.is_app_hidden()
#Now pythonshell would have disappeared from the Taskbar/Tasklist.
