Pygrok is a python library to parse strings and extract information from structured/unstructured data.It's a implementation of jordansissel's grok regular expression library.
With pygrok, you can easily:
- parsing and matching patterns in a string(log, message etc.)
- relieving from complex regular expressions.
- extracting information from structured/unstructured data
Getting Started
>>> import pygrok
>>> text = 'gary is male, 25 years old and weighs 68.5 kilograms'
>>> pattern = '%{WORD:name} is %{WORD:gender}, %{NUMBER:age} years old and weighs %{NUMBER:weight} kilograms'
>>> print pygrok.grok_match(text, pattern)
{'gender': 'male', 'age': '25', 'name': 'gary', 'weight': '68.5'}Pretty Cool ! Some of the pattern you can use are listed here:
`WORD` means \b\w+\b in regular expression.
`NUMBER` means (?:%{BASE10NUM})
`BASE10NUM` means (?<![0-9.+-])(?>[+-]?(?:(?:[0-9]+(?:\.[0-9]+)?)|(?:\.[0-9]+)))
other patterns such as `IP`, `HOSTNAME`, `URIPATH`, `DATE`, `TIMESTAMP_ISO8601`, `COMMONAPACHELOG`..See All patterns here.
