Code Climate

This repository is intended to store the python helper scripts for generating the Mantid IDFs. Each instrument is supported in its own python script.

Using

The classes that will help with creating geometry are helper.py, rectangle.py, and sns_column.py. A quick example

from helper import MantidGeom

inst_name = "VISION"

xml_outfile = inst_name+"_Definition.xml"

comment = " Created by G. Fawkes "
valid_from = "2013-11-5 00:00:01"

instr = MantidGeom(inst_name, comment=comment, valid_from=valid_from)
instr.addSnsDefaults(indirect=True)
instr.addComment("SOURCE AND SAMPLE POSITION")
instr.addModerator(-16.0)
instr.addSamplePosition()

instr.writeGeom(xml_outfile)

Testing

The test harness is small and will (generically) generate false positives, but you should run it anyway.

  1. Do your work and commit it locally
  2. git checkout origin/master or just git checkout master if you did your work on a branch
  3. ./test_unchanged.py --setup will create all the geometry files before you do your work
  4. git checkout - to go back to your latest commit/branch
  5. ./test_unchaged.py to see what (if anything) has changed

There are also tests for some of the helper classes. This is run automatically by travis-ci and can be found in the .travis.yml in the script section.
