src/ifcopenshell-python/ifcopenshell/express/README.txt

This folder contains Python code to generate C++ type information based on an
Express schema. In particular is has only been tested using recent version of
the IFC schema and will most likely fail on any other Express schema.

The code can be invoked in the following way and results in several code outputs
named according to the schema name in the Express file. A python 3 interpreter
with the pyparsing [1] library is required.

$ python bootstrap.py express.bnf > express_parser.py
$ python express_parser.py IFC2X3_TC1.exp header implementation schema_class definitions

templates.py: disable C4100 warnings for headers created by this file + move <map> inclusion to .cpp as it's not needed in .h + use spaces instead of tabs consistently for these files as seems to be the convention. 2015-11-22 02:20:34 +02:00
