parspy

A tool to parse text into a list where it can be interpreted and executed.

Install

Install using pip install parspy.

Usage

First, import and initiate the class:

import re
import parspy
parsertool = parspy.Parser()

Then, add elements to the alphabet:

parsertool.addelems("ad", "bc", " ")

If you have things more complicated than static elements, use the setregelems method by feeding it compiled regex objects:

parsertool.setregelems(number = re.compile("Number: \d+"), string = re.compile("String: '.*'"))

But what use is this without using it to parse something? None. Here is how you parse a string with this:

parsertool.parse("adbcbcbcad  Number: 123      String: 'banana!'")

The output should be:

['ad', 'bc', 'bc', 'bc', 'ad', ' ', ' ', {'number':'Number: 123'}, ' ', ' ', ' ', ' ', ' ', ' ', {'string':"String: 'banana!'"}]

Now you can pass this into a program where it can be processed more easily.

If something goes wrong during parsing, a ParseError will be thrown.

Notes

It seems to have an issue when executing in a REPL environment (name 're' is not defined).
