pxsas 1.0

Dependencies

pxsas needs a working SAS installation. SAS has to be initialized before importing pxsas into your python environment.

A note about SAS 17.0.0 and above

Starting with version 17.0.0, the SAS installation procedure creates its own python environment for running some tasks. This is the system’s default python environment after the initialization of SAS. You can install pysas in this environment, but this is extremely NOT recomended. Instead, you can redefine your PATH after SAS initialization like this (in bash):

export PATH="/path/to/my/python:$PATH"

Installation

pxsas can be easily installed using pip:

pip install pxsas

Example

A simple example of using pxsas:

import os
import pxsas

# Show SAS version used by pxsas
pxsas.sasversion(full=True)

# Show the version of the task 'evselect'
pxsas.run("evselect", "-v")

# Create a Calibration Index File for a given observation
os.environ["SAS_ODF"] = "/path/to/observation/ODF"
pxsas.run("cifbuild", calindexset="ccf.cif")

The output messages from the SAS tasks are captured through the python logging system. If the task runs succesfully, pxsas.run returns the output text as a string. If an error happens during execution, it returns None.
