Source Code Formatting Examples

When blogging, source code formatting is a huge PITA. I’m working on an Eclipse plugin to take away some of that pain. So bear with me as I play with some formatting. There is absolutely nothing useful at all in this post. This is merely a post that I can use to continually test tweaks.

Here’s some XML:

<target name="package" depends="clean,version" description="--> packages the appropriate files into the deployment-ready zip file. use this for testing; otherwise, use publish">
	<echo message="building ${zipfile}. basedir is  ${basedir}" />
	<zip destfile="${zipfile}" casesensitive="false">
		<zipfileset dir="${basedir}" 
			includes="/*.*,ant/,buildprops/,cfeclipse/,doc/,framework/,generator/,images/,PluginDemoTests/,resources/,runner/,samples/,tests/,lib/ant-contrib**" 
			excludes="MXUnitInstallTest.cfc,**/testresults/,**/junithtml/,.project,.deployment,**/unames.properties,tests/tmp/,ftp.listing,**/*.db,**/copysnippets.properties,**/copydictionary**,**/*.bak" 
			prefix="mxunit" casesensitive="false" />
	</zip>
</target>

And here’s some Java:

private static String getCommonWhitespacePrefix(String[] lines){
	//get rid of any completely blank lines, as they will throw off the getCommonPrefix function
	List<String> newLines = new ArrayList<String>();
	for (int i = 0; i < lines.length; i++) {
		if(lines[i].trim().length()>0){
			newLines.add(lines[i]);
		}
	}
	return StringUtils.getCommonPrefix(newLines.toArray(new String[newLines.size()]));
}

And some lovely ColdFusion

<cffunction name="_MixinAll" access="public">
	<cfargument name="objReceiver" required="true" hint="the object to receive the functions">
	<cfargument name="objGiver" required="true" hint="the object whose functions will be mixed in">
	<cfargument name="includedMethods" required="false" default="" hint="pass a list of methods; otherwise, all are included">
	<cfset var md = getMetadata(objGiver)>
	<cfset var a_functions = md.functions>
	<cfset var fn = 1>

	<cfset arguments.objReceiver._Mixin = _Mixin>
	<cfset arguments.objGiver._getComponentVariable = _getComponentVariable>

	<cfloop from="1" to="#ArrayLen(a_functions)#" index="fn">
		<cfif (arguments.includedMethods eq "" OR listFindNoCase(arguments.includedMethods,a_functions[fn].name))>
			<cfset arguments.objReceiver._Mixin(a_functions[fn].name,	arguments.objGiver._getComponentVariable(a_functions[fn].name))>
		</cfif>
	</cfloop>
</cffunction>

And some javascript, just to prove it looks OK

try
{
	if (window.XMLHttpRequest)
		req = new XMLHttpRequest();
	else if (window.ActiveXObject)
	{
		while (!req && Spry.Utils.msProgIDs.length)
		{
			try { req = new ActiveXObject(Spry.Utils.msProgIDs[0]); } catch (e) { req = null; }
			if (!req)
				Spry.Utils.msProgIDs.splice(0, 1);
		}
	}
}

How'd all that look?
