CFPOP – deleting an email when there is a comma in the UID

It seems that a problem has existed with the CFPOP delete action for a number of versions and it has not been fixed. The problem occurs when trying to delete a single email (or a list of emails) from the mail server where the mail server has included a comma in the UID. eg “1382396111.12731.mydomain.net,S=965”

The CF docs for the CFPOP Delete action says: “UID or a comma-separated list of UIDs to get or delete. Invalid UIDs are ignored.”

So, the abovementioned UID gets split into 2 uids (notice that it has a comma in it) and of course the email is not located so cant be deleted. CFPOP does not include a DELIMITERS parameter to use with the UID paramater which would solve the problem, I think. eg

 
<cfset myUIDlist = "1382051456.15221.mydomain.net,S=965|1382051456.18000.mydomain.net,S=966" />  
<cfpop server = "********" username = "********" password = "******** 
	action = "Delete" uid="#myUIDlist#" delimiter="|" >

Fortunately, there is a solution – use POP CFC instead of CFPOP! Thanks to Paul Vernon.

So, here is a sample page to demonstrate a way to use POP CFC.

<cfscript>
/**
 * Example of reading, processing then deleting individual emails from the pop mail server
 * using the POP CFC custom component.
 * http://popcfc.riaforge.org/
 */

	// To make it easier to rescope this example (local, variables ... whatever)
variables.s = {};

			// Initialise the custom POP CFC component. Used instead of CFPOP
			// Set your values here
s.popAccount = createObject("component", "pop").init(myPopServerHostname, myUsername, myPassword)

			// Specify a non-comma separator for the UID lists. 
			// You must do this in order for the list functionality
			// of POP CFC to work (including deletions)
s.mySeparator = "|";
s.popAccount.setProperty("separator",s.mySeparator);

			// Get an array of the UIDs of the messages in the mail account.
			// ie retrieve them from the mail server
			// This is a necessary step to solve the comma-in-uid problem
s.UIDArray = s.popAccount.getUIDList();

if (arrayLen(s.UIDArray)) {
			// Convert the array to a list
			// Keep the list to use for deletions
	s.UIDList = ArrayToList(s.UIDArray, s.mySeparator);

			// Get an array of the raw messages - one entry per UID supplied
			// This gets the raw email data from the pop server for whichever
			// emails are in the UIDList
	s.msgSrcArray = s.popAccount.GetRawMessageByUID(s.UIDList);

			// Turn the array into a query of email structures
	s.messagesQry = s.popAccount.parseRawMessage(s.msgSrcArray);

			// Loop over the array of email messages
	for( s.i=1; s.i <= s.messagesQry.recordcount; s.i=s.i+1) {

			// Process the message as you wish
			// ....
		
		writeOutput("<br/>" & s.messagesQry.subject[s.i]);


			// Now, delete this email from the server 
			// Note: you can also delete all the emails in your query 
			// in one go after the loop. See below.

			// The UID is NOT present in the messagesQry. Therefore,
			// you need to look up the UID by list position.
			// Obviously, you can also selectively delete single messages 
			// based on your criteria.

		s.uid = listGetAt(s.UIDList, s.i, s.mySeparator);
		s.popAccount.deleteMessagesByUID(s.uid);

	}

			// Uncomment to delete all messages in the list in one go, 
			// instead of one by one as above
	//s.popAccount.deleteMessagesByUID(s.UIDList);
}

</cfscript>

POP CFC has lots of other useful functions too.

Sublime Text – exclude / include search folders using regex

I recently switched from Eclipse to Sublime Text 3 and am very happy I did. It is fast to load, lots of extensions, active community.

One thing that I couldnt figure out was how to exclude folders from the search within files (project). I mostly code in JS (Sencha Ext/Touch) and ColdFusion and keep my JSDuck API Docs etc in the same project folder as my source files. That means that when I search within files in my project I end up with matches from the docs folder, which is not what I want. Also, and probably more importantly, when using Sencha Cmd to build production apps there is a /build folder which I do not want to search in since that is the “compiled” output.

There is a forum post about using -/my/path/to/folderToExclude (ie prefix the path with a – ). http://sublimetext.userecho.com/topic/97052-find-in-files-exclude-directories/

For Windows (which I use) you need backslashes instead of forward slashes and the syntax becomes odd (IMJ). At the end of that post was an example of using regex in the Where input box. This was a revelation.

So, to exclude the various folders within my project that I never want to search in, my where box looks like:

-*/docs/*,-*/build/*,-*/ext/*,-*/sass/*

which means search in all folders and subfolders in the project except these ones. Brilliant!

By the same method you can be specific about which folder to include. eg:

*/app/* will find a match in all “app” folders (and sub folders of course) eg myappname/app and myappname/build/app. However I want the first one but not the second one (build). So:

*/myappname/app/*

does the trick, only searching in folder (and sub folders of) myappname/app.

And, of course you can combine exclude and include:

*/myappname/app/*,-*/controller/*

ie only search in myappname/app/ but NOT in myappname/app/controller (or any sub folder with ‘controller’ in the path)

Finally, dont forget that the Where box is cached and previous contents are available by clicking the down arrow at the end of the input box. So, you can easily switch between saved search strings.

All very nifty!
