Use Production Facility (stats.com) instead of SpssClient to run .sps

[fomcl]

Hi,

From the readme: "To use the run selected code in SPSS tool
1.Make sure you have SPSS already running"

If you use the Production Facility, you only use a costly license when you actually run the .sps.
The Production Facility takes an .spj while (which is actually an .xml file) that itself calls one of more .sps files. When you're done, you can use the free smartreader to view the output (.spv).

Code fragment:

stats = r"C:\PROGRA~1\IBM\SPSS\STATIS~1\22\stats.com"
reader = r"C:\PROGRA~1\IBM\SPSS\Smartreader\21\reader.exe"

# this has the locale and locale/codepage  setting hard-coded. Not nice, but good enough for my purposes
def create_spj(syntaxPath, outputPath, productionPath):
    """create the SPSS production facility file (.spj)"""
    spj_template = '''\
    <job xmlns="http://www.ibm.com/software/analytics/spss/xml/production"

    logger.debug("create .spj:" + spj_template % locals())
    with open(productionPath, "w") as f:
        f.write(spj_template % locals())
