# Description
arya is a tool that will convert APIC object documents from their XML or JSON
form into the equivalent Python code leveraging the Cobra SDK.
arya supports input in a number of formats, including XML, JSON, a directory containing
multiple xml or json documents, as well as standard input. The standard input
option is very useful for use as a filter in most text editors, where one
can copy the JSON or XML extracted from APIC Visore or API inspector, and quickly
generate the Python source code framework, which can then be modified, tokenized
and rapidly turned into functional prototypes.
Note that arya is a very useful tool for the heavy lifting of converting object
model into source code, however it does not validate configuration, perform
advanced lookup logic or implement a number of best practices that should be
followed, such as performing lookups to validate targets, referencing object
attributes instead of hardcoding Dns and names, and other proper coding practices
It is strongly recommended that for advanced use cases, getting expert advice
and validating your code, you reach out to Cisco Advanced Services for support.

$ arya.py
# Usage
Once installed arya will place the file `arya.py` in your path, so you should be able to call `arya.py` from any prompt.
Usage is as such:
$ arya.py
usage: Code generator for APIC cobra SDK [-h] [-f FILEIN] [-s] [-d SOURCEDIR]
[-t TARGETDIR] [-i IP] [-u USERNAME]
[-p PASSWORD] [-nc] [-b]
optional arguments:
-h, --help show this help message and exit
-f FILEIN, --filein FILEIN
Document containing post to be sent to REST API
-s, --stdin Parse input from stdin, for use as a filter, e.g., cat
doc.xml | arya.py -s
-d SOURCEDIR, --sourcedir SOURCEDIR
Specify a source directory containing ACI object files
you want to convert to python.
-t TARGETDIR, --targetdir TARGETDIR
Where to write the .py files that come from the -d
directory. If none is specified, it will default to
SOURCEDIR
-i IP, --ip IP IP address of APIC to be pre-populated
-u USERNAME, --username USERNAME
Username for APIC account to be pre-populated in
generated code
-p PASSWORD, --password PASSWORD
Password for APIC account to be pre-populated in
generated code
-nc, --nocommit Generate code without final commit to changes
-b, --brief Generate brief code (without headers, comments, etc)
Password for admin account on APIC
