Python Code Generation

Since FESA3 2.x a part of the code generation is done with Python instead of XSLT. One of the goals of this change is to be able to debug the code generation and to have more possibilities than with the functional programming language XSLT.

Setup

Project	Location	Softlink to
fesa-codegen	src/libs	springpython -> /usr/lib/python2.6/site-packages/springpython/
fesa-codegen	Makefile.dep	LIB_SPINGPYTHON_HOME = /usr/lib/python2.6/site-packages/springpython/
fesa-codegen-gsi	src/libs	springpython -> /usr/lib/python2.6/site-packages/springpython/
fesa-codegen-gsi	src/py/	codegen -> ../../../fesa-codegen/src/py/codegen

Eclipse:

• before launching Eclipse set the PYTHONPATH environment variable, e.g. export PYTHONPATH=/home/bel/matthies/lnx/workspaceFesaFWK2.0.1/fesa-codegen/src/py/:/home/bel/matthies/lnx/workspaceFesaFWK2.0.1/fesa-codegen-gsi/src/py/ . If PyDev is installed a dialog will appear during the launch of Eclipse to confirm the content of PYTHONPATH.
• install PyDev from update site http://update-production-pydev.s3.amazonaws.com/pydev/updates
• set libs, src, test as source folders (right click in Project Explorer, PyDev > Set As Source Folder)

Usage

• Edit Run Configurations, configure Python Runs or Python unittest
• right click in Project Explorer, run as > Python

Debugging specific FESA design files

To debug a specific Python controller similar to the Eclipse plug-in call:

• Create a new run configuration:
  • Project: fesa-codegen-gsi
  • Main module: ${workspace_loc:fesa-codegen-gsi/src/py/Generate.py}
  • Program arguments: $sourceFilePath $outputDirPath $controllerName(s), e.g. --overwrite /common/home/bel/matthies/lnx/runtime-EclipseApplicationLuna/UEye/src/UEye.design /common/home/bel/matthies/lnx/runtime-EclipseApplicationLuna/UEye/generated/cpp/UEye/GeneratedCode PropertyData
  • Working directory: set to ${workspace_loc:fesa-codegen-gsi/src/py}
• Create a new run configuration automatically by right-clicking on a Python test and adapt the working directory manually.
