=======
Caching
=======
This example shows how to use caching. This can be useful
for big projects where you don't want the c++ to be parsed
again and again.
Let's consider the following c++ file:
.. literalinclude:: example.hpp
:language: c++
:lines: 5-
To enable caching, you can use the following code:
.. literalinclude:: example.py
:language: python
:lines: 6,7,8,17-27,29-
The first time you run this example, the c++ file will be read and a xml
file will be generated:
INFO Creating xml file "example.hpp.xml" from source file "example.hpp" ...
INFO Parsing xml file "example.hpp.xml" ...
My name is: ns
The second time you run the example the xml file will not be regenerated:
INFO Parsing xml file "example.hpp.xml" ...
My name is: ns
Of course the performance gain will be small for this example,
but can be intersting for bigger projects.
