Feature Request: is_gimp, is_krita, is_paintnet

[Reptorian]

Sometimes gmic filters do not work on specific softwares due to limitations or bugs associated with host programming. There are some times when I make filters, and then realize paint.netcannot use it. So, I would like to make error output say "Incompatible with Paint.NET".

Good idea.

Variable $_host can help you.

[David_Tschumperle (G'MIC staff)]

To be more precise, $_host is a pre-defined variable whose value is a string that tells on which host the G’MIC interpreter is running.

• For the command-line tool:

dtschump@gmicky:~/work/src/gmic/src$ gmic e \$_host
[gmic]-0./ Start G'MIC interpreter.
[gmic]-0./ cli
[gmic]-0./ End G'MIC interpreter.

• For the plug-in G’MIC-Qt for GIMP:

• For the plug-in G’MIC-Qt for Krita:

(I suppose something similar for the Paint.NET version).

• In a filter code, you can then easily test on which platform the plug-in is running:

foo:
  if '$_host'=='gimp'
    ...
  elif '$_host'=='krita'
    ...
  else # Other hosts
    ...
  fi
