PyParsing -- A Python Parsing Module
|
||||
====================================
|
||||
|
||||
|Build Status|
|
||||
|
||||
Introduction
|
||||
============
|
||||
|
||||
The pyparsing module is an alternative approach to creating and
|
||||
executing simple grammars, vs. the traditional lex/yacc approach, or the
|
||||
use of regular expressions. The pyparsing module provides a library of
|
||||
classes that client code uses to construct the grammar directly in
|
||||
Python code.
|
||||
|
||||
*[Since first writing this description of pyparsing in late 2003, this
|
||||
technique for developing parsers has become more widespread, under the
|
||||
name Parsing Expression Grammars - PEGs. See more information on PEGs at*
|
||||
https://en.wikipedia.org/wiki/Parsing_expression_grammar *.]*
|
||||
|
||||
Here is a program to parse ``"Hello, World!"`` (or any greeting of the form
|
||||
``"salutation, addressee!"``):
|
||||
|
||||
.. code:: python
|
||||
|
||||
from pyparsing import Word, alphas
|
||||
greet = Word(alphas) + "," + Word(alphas) + "!"
|
||||
hello = "Hello, World!"
|
||||
print(hello, "->", greet.parseString(hello))
|
||||
|
||||
The program outputs the following::
|
||||
|
||||
Hello, World! -> ['Hello', ',', 'World', '!']
|
||||
|
||||
The Python representation of the grammar is quite readable, owing to the
|
||||
self-explanatory class names, and the use of '+', '|' and '^' operator
|
||||
definitions.
|
||||
|
||||
The parsed results returned from ``parseString()`` can be accessed as a
|
||||
nested list, a dictionary, or an object with named attributes.
|
||||
|
||||
The pyparsing module handles some of the problems that are typically
|
||||
vexing when writing text parsers:
|
||||
|
||||
- extra or missing whitespace (the above program will also handle ``"Hello,World!"``, ``"Hello , World !"``, etc.)
|
||||
- quoted strings
|
||||
- embedded comments
|
||||
|
||||
The examples directory includes a simple SQL parser, simple CORBA IDL
|
||||
parser, a config file parser, a chemical formula parser, and a four-
|
||||
function algebraic notation parser, among many others.
|
||||
|
||||
Documentation
|
||||
=============
|
||||
|
||||
There are many examples in the online docstrings of the classes
|
||||
and methods in pyparsing. You can find them compiled into online docs
|
||||
at https://pyparsing-docs.readthedocs.io/en/latest/. Additional
|
||||
documentation resources and project info are listed in the online
|
||||
GitHub wiki, at https://github.com/pyparsing/pyparsing/wiki. An
|
||||
entire directory of examples is at
|
||||
https://github.com/pyparsing/pyparsing/tree/master/examples.
