Examples

Select a logfile and send it to the Client

import os

from ppms.user_interface import ask_user_to_select_from_list, store_file


def get_all_logfiles():
    return [logfile for logfile in os.listdir('log') if logfile.endswith('.log')]
    
def ending_stripper(logfile):
    return logfile.rstrip('.log')
    
    
logfiles = get_all_logfiles()
selected_logfile = ask_user_to_select_from_list(possible_values=logfiles, heading='Please select a logfile:', transform_value_to_text=ending_stripper)

if selected_logfile is not None:
    logfile_path = os.path.join('log', selected_logfile)
    
    with open(logfile_path, 'rb') as logfile:
        title = 'Where do you want to save this logfile?'
        filter = 'Log files (*.log)|*.log|All files (*.*)|*.*'
        
        store_file(local_file=logfile, title=title, filter=filter, suggested_filename=selected_logfile)
