Python package "CppHeaderParser"
--------------------------------
**Purpose:** Parse C++ header files and generate a data structure representing the class
**Author:** Jashua Cloutier (jashuac@bellsouth.net)
**Licence:** BSD
**External modules required:** PLY
**Quick start**::
#include <vector>
#include <string>
using namespace std;
class SampleClass
{
public:
SampleClass();
/*!
* Method 1
*/
string meth1();
///
/// Method 2 description
///
/// @param v1 Variable 1
///
int meth2(int v1);
/**
* Method 3 description
*
* \param v1 Variable 1
* \param v2 Variable 2
*/
void meth3(const string & v1, vector<string> & v2);
/**********************************
* Method 4 description
*
* @return Return value
*********************************/
unsigned int meth4();
private:
void * meth5(){return NULL};
/// prop1 description
string prop1;
//! prop5 description
int prop5;
};
namespace Alpha
{
class AlphaClass
{
public:
AlphaClass();
void alphaMethod();
string alphaString;
};
namespace Omega
{
class OmegaClass
{
public:
OmegaClass();
string omegaString;
};
};
}
**Python code**::
#!/usr/bin/python
import sys
sys.path = ["../"] + sys.path
import CppHeaderParser
try:
cppHeader = CppHeaderParser.CppHeader("SampleClass.h")
except CppHeaderParser.CppParseError, e:
print e
sys.exit(1)
print "CppHeaderParser view of %s"%cppHeader
sampleClass = cppHeader.classes["SampleClass"]
print "Number of public methods %d"%(len(sampleClass["methods"]["public"]))
print "Number of private properties %d"%(len(sampleClass["properties"]["private"]))
meth3 = [m for m in sampleClass["methods"]["public"] if m["name"] == "meth3"][0] #get meth3
meth3ParamTypes = [t["type"] for t in meth3["parameters"]] #get meth3s parameters
print "Parameter Types for public method meth3 %s"%(meth3ParamTypes)
print "\nReturn type for meth1:"
print cppHeader.classes["SampleClass"]["methods"]["public"][1]["rtnType"]
print "\nDoxygen for meth2:"
print cppHeader.classes["SampleClass"]["methods"]["public"][2]["doxygen"]
print "\nParameters for meth3:"
print cppHeader.classes["SampleClass"]["methods"]["public"][3]["parameters"]
print "\nDoxygen for meth4:"
print cppHeader.classes["SampleClass"]["methods"]["public"][4]["doxygen"]
print "\nReturn type for meth5:"
print cppHeader.classes["SampleClass"]["methods"]["private"][0]["rtnType"]
print "\nDoxygen type for prop1:"
print cppHeader.classes["SampleClass"]["properties"]["private"][0]["doxygen"]
print "\nType for prop5:"
print cppHeader.classes["SampleClass"]["properties"]["private"][1]["type"]
print "\nNamespace for AlphaClass is:"
print cppHeader.classes["AlphaClass"]["namespace"]
print "\nReturn type for alphaMethod is:"
print cppHeader.classes["AlphaClass"]["methods"]["public"][0]["rtnType"]
print "\nNamespace for OmegaClass is:"
print cppHeader.classes["OmegaClass"]["namespace"]
print "\nType for omegaString is:"
print cppHeader.classes["AlphaClass"]["properties"]["public"][0]["type"]
**Output**::
