No user interaction. The gphoto cmd to return iso is calling by node.js for automatic scripting. The filtered result by a nested sed or greb command should return always the integer of the current iso setting.

User will changes the iso on the camera and the automated script monitoring periodically the current iso.

There is a weakness of the call gphoto2 --get-config /main/imgsettings/iso it returns the current value but all the time the enum.

My script calls internally and autom.
gphoto2 --get-config /main/imgsettings/iso | sed <nested commands>
to return the index of current iso setting only for further processin.

libgphoto2

LIBGPHOTO2(3)						  The gPhoto2 Reference (the man					     LIBGPHOTO2(3)

NAME

       libgphoto2 - cross-platform digital camera library

SYNOPSIS

       #include <gphoto2/gphoto2.h>

DESCRIPTION

       The gphoto2 library provides applications with access to a variety of cameras.

       This man page will be extended with autogenerated documentation of the interface types and methods used for communication between the
       gphoto2 library and a frontend.

FILES

       ~/.gphoto/settings
	      Here gphoto2 applications may store their configuration used to access gphoto2.

       To track down errors, you can add the --debug parameter to the gphoto2 command line and, if dealing with USB problems, setting the
       environment variable USB_DEBUG=1.

ENVIRONMENT VARIABLES

       CAMLIBS
	      If set, defines the directory where the libgphoto2 library looks for its camera drivers (camlibs). You only need to set this on OS/2
	      systems and broken/test installations.

       IOLIBS If set, defines the directory where the libgphoto2_port library looks for its I/O drivers (iolibs). You only need to set this on
	      OS/2 systems and broken/test installations.

       LD_DEBUG
	      Set this to all to receive lots of debug information regarding library loading on ld based systems.

       USB_DEBUG
	      If set, defines the numeric debug level with which the libusb library will print messages. In order to get some debug output, set it
	      to 1.
