This script generates Python wrappers to interface with the C++
|
||
|
|
libraries that have already been run through interrogate. It is
|
||
|
|
necessary to run this script after building the Panda tools for the
|
||
|
|
first time, or after any major change in which some of the interface
|
||
|
|
may have changed.
|
||
|
|
|
||
|
|
The default options are baked into genPyCode by ppremake and need not
|
||
|
|
be specified. However, it is possible to override these on the
|
||
|
|
command line if you need to fine-tune the behavior of genPyCode for
|
||
|
|
some reason. Most often, the only needed change will be to add one or
|
||
|
|
more additional libraries to the list of libraries instrumented by
|
||
|
|
default.
|
||
|
|
|
||
|
|
|
||
|
|
Options:
|
||
|
|
-h print this message
|
||
|
|
-v verbose
|
||
|
|
-d generate HTML documentation too
|
||
|
|
-C dir directory to write output code
|
||
|
|
-H dir directory to write output HTML
|
||
|
|
-x dir directory to pull extension code from
|
||
|
|
-i lib interrogate library
|
||
|
|
-e dir directory to search for *.in files (may be repeated)
|
||
|
|
-p dir directory to search for Python source files (may be repeated)
|
||
|
|
-r remove the default library list; instrument only named libraries
|
||
|
|
-O no C++ comments or assertion statements
|
||
|
|
-n Don't use squeezeTool to squeeze the result into one .pyz file
|
||
|
|
-s Don't delete source files after squeezing
|
||

Any additional names listed on the command line are taken to be names
|

|
|
of libraries that are to be instrumented.
