Installing
**********

It's working on Ubuntu 18.04 with Zebra SDK 4.4, which you can download from https://www.zebra.com/de/de/support-downloads/software/developer-tools/scanner-sdk-for-linux.html
You can easily install zebra_scanner with pip:

.. code-block:: sh

 sudo apt-get install libboost-dev libboost-python-dev libpugixml-dev
 sudo pip3 install pybind11
 sudo pip3 install . # in zebra-scanner directory


*****************
A minimal example
*****************

.. code-block:: python

 import pprint
 import time
 
 from zebra_scanner import CoreScanner
 
 pp = pprint.PrettyPrinter(indent=4)
 scanners = []
 cs = CoreScanner()
 
 
 @cs.on_scanner_added
 def on_scanner_added(scanner):
     print("New scanner found:")
     pp.pprint(scanner.__dict__)
     scanners.append(scanner)
     scanner.pull_trigger()
 
     scanner.fetch_attributes()
     for id, attribute in scanner.attributes.items():
         if id<10:
             pp.pprint({
                 "id": id,
                 "datatype": attribute.datatype,
                 "value": attribute.value,
                 "permission": attribute.permission
             })
 
     @scanner.on_barcode
     def on_barcode(barcode):
         print("Scanned:")
         print(barcode.code, barcode.type)
 
 @cs.on_scanner_removed
 def on_scanner_removed(scanner):
     print("Scanner removed:")
     scanner.release_trigger()
     scanners.remove(scanner)
     pp.pprint(scanner.__dict__)
 
 while True:
     time.sleep(0.1)
     # do nothing while the scanner is reading in continous mode
