用ruby写了一个生成xpcom组件模板的小工具

写xpcom组件我们经常copy paste,因为xpcom组件的与业务无关的注册、QueryInterface代码都是基本固定的,
写了一个自动生成xpcom组件的template,这样就可以只关心核心业务,避免书写样板式的代码。

=begin
NOTICE:
Before use the code:
You should use command "gem install uuid" to install uuid gem for ruby
Once installed, create a uuid.state file by running command "uuid-setup"
=end

require 'uuid'

puts "please input the component interface name:"
component_interface_name = gets.chomp

puts "please input the component class name:"
class_name = gets.chomp
cid = "{#{UUID.new}}";

template = <<EOF
const Cc = Components.classes;
const Ci = Components.interfaces;
const Cr = Components.results;

const nsISupports = Ci.nsISupports;
const #{component_interface_name}  =  Ci.#{component_interface_name};

const CLASS_ID = Components.ID("#{cid}");
const CLASS_NAME = "#{class_name}";
const CONTRACT_ID = "@ibm.com/#{class_name.downcase};1";

function #{class_name}(){
};

#{class_name}.prototype = {

	QueryInterface: function(aIID){
		if(!aIID.equals(#{component_interface_name}) && 
		   !aIID.equals(nsISupports)) 
			throw Cr.NS_ERROR_NO_INTERFACE;
		return this;
	}
};	
	
var #{class_name}Factory = {
	createInstance: function(aOuter, aIID){
		if(aOuter != null)
			throw Cr.NS_ERROR_NO_AGGREGATION;
		return (new #{class_name}()).QueryInterface(aIID);
	}
};

var #{class_name}Module = {
	registerSelf: function(aComMgr, aFileSpec, aLocation, aType){
		aComMgr = aComMgr.QueryInterface(Ci.nsIComponentRegistrar);
		aComMgr.registerFactoryLocation(CLASS_ID, CLASS_NAME, CONTRACT_ID, aFileSpec, aLocation, aType);
	},
	
	unregisterSelf: function(aComMgr, aLocation, aType){
		aComMgr = aComMgr.QueryInterface(Ci.nsIComponentRegistrar);
		aComMgr.unregisterFactoryLocation(CLASS_ID, aLocation);
	},
	
	getClassObject: function(aComMgr, aCID, aIID){
		if(!aIID.equals(Ci.nsIFactory))
			throw Cr.NS_ERROR_NO_IMPLEMENTED;
		if(aCID.equals(CLASS_ID))
			return #{class_name}Factory;
		throw Cr.NS_ERROR_NO_INTERFACE;
	},
	
	canUnload: function(aComMgr){
		return true;
	}
};

function NSGetModule(aComMgr, aFileSpec){
	return #{class_name}Module;
};
EOF

file_name = "#{class_name}.js"

File.open(file_name,"w") do |file|
   file.puts template
end

 生成idl文件:

=begin
NOTICE:
Before use the code:
You should use command "gem install uuid" to install uuid gem for ruby
Once installed, create a uuid.state file by running command "uuid-setup"
=end

require 'uuid'

puts "please input the component interface name:"
component_interface_name = gets.chomp

template = <<EOF
#include "nsISupports.idl"

[scriptable, uuid(#{UUID.new})]
interface #{component_interface_name} : nsISupports{

};
EOF

file_name = "#{component_interface_name}.idl"

File.open(file_name,"w") do |file|
   file.puts template
end
