Fast Parse - A fast way to get terminal arguments!

With Fast Parse, you can get command line and terminal arguments in an easy and convenient way. With only one line of code.

Overview

The Fast Parse module provides the following features:

• An easy way to get a basic command line or terminal arguments.
• If the user doesn't give the arguments in the command line, they will need to give them through the input.

• First, you need to download it from pip. pip install fastparse

• Then import it to your project.

from fastparse import fast_parse, try_parse

fast_parse

This function is THE function. fast_parse enables you to get command lines arguments with one line of code, as following.

args = fast_parse('all', 'of', 'your', 'command', 'line', 'arguemtns')

# later on you can get the argumetns from the 'args' variable
all_value = args.get('all')

print(all_value)

Now it's time to let the user add the arguemnts.

python main.py 'all_value_here' 'of_value_here' 'your_value_here', 'command_value_here', 'line_value_here', 'arguments_value_here'

The output is:

all_value_here

Note: the fast_parse function returns a value (in the above example we called it 'args'), this value is a dictionary.

try_parse

try_parse is a bit more exciting than fast_parse, it lets the user add the arguments in the command line and if they don't, it asks them to give the args in the input.

Let's look at an example,

args = try_parse('arg1', 'arg2')

arg1_value = args.get('arg1')

print(arg1_value)

If we give the arguments in the terminal it works just as fast_parse

python main.py 'arg1_value_here' 'arg2_value_here'

Output is as expected: arg1_value_here

But if we don't give the arguments in the command line, it asks the arguments in the input

python main.py
enter arg1 value: arg1_value
enter arg2 value: arg2_value

And the output is: arg2_value
