If you are a Windows Programmer, I would like to introduce
something intersting to you.
COMer is a native programming language for COM
component
development.
A COM component can be easily made in COMer as follow:
[File:
MyCom.cm]
#ifndef _MYCOM_CM
#define _MYCOM_CM
/*
* A COM Class
*/
[ clsid = "{EF6CD47E-B844-4219-B582-6F9FE16D45F6}",
progid = "Dexterity.MyCom1.1",
helpstring = "Dexterity Com1 Class",
export, unhandle ]
com CMyCom1
{
/*
* An Interface implemented in this class
*/
[iid="{A123799B-1D8B-4efb-8D43-42AE582767C1}"]
interface IMyInterface
{
method SetValue(int dVal)
{
m_dValue = dVal;
done;
}
method GetDoubleValue(int &dVal)
{
dVal = m_dValue << 1;
done;
}
}
/*
* Instance variables
*/
instvars
{
int m_dValue;
}
}
#endif
The design of COMer is native to the concept of the
Component
Object Model (COM) machanism. COM classes are defined as in
the
way that COM specifies. Interfaces are specified or defined
within
a COM class and the methods of the interfaces are defined
within
the interfaces. It is simple.
A special characteristic of COMer is that the COMer
compiler
generates C++ source code files as its final outputs.
Therefore,
you can use C++ code within the COMer classes, like Lex, Yacc
or
MIDL. To build the component, what you need to do is to
specify
one more file only to indicate the module of the component to
build.
E.g: [File:MyCom.cmdef]
module: inprocsvr
source { MyCom.cm }
Then, by the following command line (cmc is the COMer
compiler
program):
> cmc MyCom.cmdef
COMer compiler will generate the following C++
files:
Main.cpp
MyCom.h
MyCom.cpp
MyCom.def
Makefile
Finally, you only need to build these C++ files by using
the
generated makefile by C++ build tools. The component
'MyCom.dll'
will then be made. It's so simple!
