Introduction: What is Nety?
=====================================
Nety is a Python_ library, which parses through Cisco IOS-style
(and other vendor) configurations. It can:
- Audit existing router / switch / firewall / wlc configurations
- Retrieve portions of the configuration
- Modify existing configurations
- Build new configurations
The library examines an IOS-style config and breaks it into a set of linked
parent / child relationships. You can perform complex queries about these
relationships.

What if we don't use Cisco?
===========================
Don't let that stop you.
As of Nety 1.2.4, you can parse `brace-delimited configurations`_
into a Cisco IOS style (see `Github Issue #17`_), which means that
Nety understands these configurations:
- Juniper Networks Junos, and Screenos
- F5 Networks configurations
Nety also handles anything that has a Cisco IOS style of configuration, which includes:
- Cisco IOS, Cisco Nexus, Cisco IOS-XR, Cisco IOS-XE, Aironet OS, Cisco ASA, Cisco CatOS
- Arista EOS
- Brocade
- HP Switches
- Force 10 Switches
- Dell PowerConnect Switches
- Extreme Networks
- Enterasys

.. _Pre-Requisites:
Pre-requisites
==============
Nety_ requires Python versions 3.5+ (We no longer support Python 2.x); the OS should not
matter. If you want to run it under a Python virtualenv_, it's been heavily
tested in that environment as well.
.. _Installation:
Installation and Downloads
==========================
The best way to get Nety is with setuptools_ or pip_. If you
already have setuptools_, you can install as usual:
::
# Substitute whatever Nety version you like...
easy_install -U nety==1.3.0
Alternatively you can install into Python2.x with pip_:
::
pip install --upgrade Nety
Use ``pip3`` for Python3.x...
::
pip3 install --upgrade Nety
Otherwise `download it from PyPi <https://pypi.python.org/pypi/Nety>`_, extract it and run the ``setup.py`` script:
::
python setup.py install
If you're interested in the source, you can always pull from the `github repo`_:
- From github_:
::
git clone https://github.com/YtenSoftware/Nety.git
.. _FAQ:
FAQ
===
#) *QUESTION*: I want to use Nety_ with Python3; is that safe? *ANSWER*: As long as you're using Python 3.3 or higher, it's safe. I test every release against Python 3.2+; however, Python 3.2 is currently exposed to a small bug for some configurations (see `Github Issue #14`_).
#) *QUESTION*: Some of the code in the documentation looks different than what I'm used to seeing. Did you change something? *ANSWER*: Yes, starting around Nety_ v0.9.10 I introducted more methods directly on ``IOSConfigLine()`` objects; going forward, these methods are the preferred way to use Nety_. Please start using the new methods shown in the example, since they're faster, and you type much less code this way.
#) *QUESTION*: Nety_ saved me a lot of time, I want to give money. Do you have a donation link? *ANSWER*: I love getting emails like this; helping people get their jobs done is why I wrote the module. However, I'm not accepting donations.
#) *QUESTION*: Is there a way to use this module with perl? *ANSWER*: Yes, I do this myself. Install the python package as you normally would and import it into perl with ``Inline.pm`` and ``Inline::Python`` from CPAN.
#) *QUESTION*: When I use ``find_children("interface GigabitEthernet3/2")``, I'm getting all interfaces beginning with 3/2, including 3/21, 3/22, 3/23 and 3/24. How can I limit my results? *ANSWER*: There are two ways... the simplest is to use the 'exactmatch' option... ``find_children("interface GigabitEthernet3/2", exactmatch=True)``. Another way is to utilize regex expansion that is native to many methods... ``find_children("interface GigabitEthernet3/2$")``
