Reptorian G'MIC Filters

[Reptorian]

I found a easier way of doing this that’s pretty flexible:

In my example yes, but if you need more complex selections, there is another solution : define your own (temporary) command that returns whatever you want, then call it with the original parameters.
Like in this example:

foo :
  a=2
  b=5
  m "temp : u ${"$a-$b"}" # Return a subset of arguments
  temp $"*"
  echo ${}
  um temp

then:

$ gmic foo 1,2,3,4,5,6,7,8
[gmic]./ Start G'MIC interpreter (v.3.3.1).
2,3,4,5
[gmic]./ End G'MIC interpreter.

The key idea here is that you can define your own command where the command code depends itself of some variables you have computed before.

My solution is this:

rep_custom_command_test:
m "temp:
	m \"$0_temp:u ${\"$""1--1:$""2\"}\"
	$0_temp $*
	um $0_temp
	"
echo ${temp\ $1,$2}

This is going to be used in another attempt of gui_toolkit_pal, and this time I coded in printing of available of global arguments.
