Python CMD autocomplete

Question

I am currently working on creating a command line interface using the Python's CMD module.This command line takes multiple arguments for various functions in the form:" command parametre1=value1 parametre2=value2 " and so on .I want to setup an TAB autocomplete feature for the parametre's names along with the command name. The commmand name Autocomplete is done but struggling with the Parametre's autcomplete. Help

It's not clear what parts of the problem are solved and which ones are unsolved, nor exactly where you have trouble. — Brian Cain

I think this does what you want it to do:

import cmd


class MyCmd(cmd.Cmd):
    def do_command(self, line):
        'do_command: [parametre[1,2]=xxx]'

    def complete_command(self, text, line, begidx, endidx):
        return [i
                for i in ('parametre1=', 'parametre2=')
                if i.startswith(text)]

    def do_EOF(self, line):
        'exit the program. Use  Ctrl-D (Ctrl-Z in Windows) as a shortcut'
        return True

if __name__ == "__main__":
    myCmd = MyCmd()
    myCmd.cmdloop("Welcome! What is your command?")
