Python Interface: getting active gcodes was created by fletch

I'm trying to clean up the Manualmatic G5x offset functionality and need to find out if G90 or G91 is active. The Python Interface kindly offers

linuxcnc.stat.gcodes

: "Active G-codes for each modal group. G code constants G_x - G_xxx" so I naively expected a quick

if ( self.linuxcnc.G_90 ) in self.ls.gcodes:

would see me right but it would appear G_90 is not a constant of

linuxcnc

(nor is it of

stat

command

.

I also tried a string, as in

if ( "G_90" ) in self.ls.gcodes:

but even after explicitly setting G90 via MDI the response is still negative.

Any help in using the

linuxcnc.stat.gcodes

would be greatly appreciated and as a bonus, an understanding of what "for each modal group" means also, because I think that might be relevant...

As a PS, is there an automatically generated 'API doc' for the Python Interface available? The Python Interface doc is really useful but sometimes there's a need to dig a little deeper (and I still can't find the source!)

IIRC linuxcnc.stat.gcodes should contain a list of integers, G90 would be 900, G91 910 and so on. github.com/LinuxCNC/linuxcnc/blob/master...k/taskmodule.cc#L441

import sys
import linuxcnc

try:
    s = linuxcnc.stat() # create a connection to the status channel
    s.poll() # get current values
except Exception as detail:
    print("error", detail)
    sys.exit(1)

print(s.gcodes)

if 900 in s.gcodes:
    print("G90 active")
elif 910 in s.gcodes:
    print("G91 active")

Many thanks Robert and Oliver - the Python Interface is a little misleading when it describes 'G code constants' as G_90 and G_91 so it didn't occur to me to drop the 'G_'.

Gstat might be useful tool.
