dissec 1.2

Dissect pattern implementation for ElasticSearch

He attac, he protec, but most importantly, he dissec.

dissec is a Python module used for implementing string dissection patterns, compatible with ElasticSearch’s Dissect processor.

The project is present at the following locations:

• Official website and documentation;

• Official repository on Gitlab;

• Official project on PyPI.

For example, you can dissect a string using this module with the following snippet:

from dissec.patterns import Pattern

pattern = Pattern.parse(
    r'%{clientip} %{ident} %{auth} [%{@timestamp}] \"%{verb} %{request} '
    + r'HTTP/%{httpversion}\" %{status} %{size}',
)
result = pattern.dissect(
    r'1.2.3.4 - - [30/Apr/1998:22:00:52 +0000] '
    + r'\"GET /english/venues/cities/images/montpellier/18.gif '
    + r'HTTP/1.0\" 200 3171',
)
print(result)

This will print the following, pretty-printed here for readability purposes:

{'@timestamp': '30/Apr/1998:22:00:52 +0000',
 'auth': '-',
 'clientip': '1.2.3.4',
 'httpversion': '1.0',
 'ident': '-',
 'request': '/english/venues/cities/images/montpellier/18.gif',
 'size': '3171',
 'status': '200',
 'verb': 'GET'}
