Gcode parser

Hi,

I'm looking to understand how LinuxCNC parses G-code into commands. Could you point me to any documentation or resources that explain this process?

Thanks

I'm not aware of any documentation on gcode parsing but maybe you can find information in the source code:
github.com/LinuxCNC/linuxcnc/tree/master/src/emc/rs274ngc

Have you read this part of the Linuxcnc user manual. It may clear up some of the questions you might have.
