OSX GNU Guile — beating libltdl into submission

After encountering an issue with socket handling in the remote REPL server code I needed to build guile from source but it just wouldn’t.

I downloaded a mint latest source from http://www.gnu.org/software/libtool/ and gave it this spell:
./configure --prefix=/opt/local
to make it overwrite the Mac Porst version to see if that would fix it.
It didn’t.

After further close reading of the configure help text for guile the answer was there as usual, resulting in this incantation:
./configure --with-libltdl-prefix=/opt/local --prefix=/opt/local

Result… clean run of the configure script!

Now all I have to do is build it and get to the bottom of the problem. Apparently it only happens on OSX, Ubuntu is not affected, nor presumably is any other *nix.
Oddly, geiser mode works, if that is using com-int buffers then I don’t see why I cannot then use telnet or netcat to connect to the REPL server. We’ll see!

It’s got something to do with opening a socket in non-blocking mode then send() thinks the output buffer is full. I’ll spare you the details but just in case you are interested the bug report is here (original), I submitted a new one with lots more information but it’s not on the list yet.

PHP and Lisp: multiple-value-bind (MVB)

This is another article in my attempts to find new ways of looking at PHP and making it less of a chore to type in all that code. As much as I love PHP I hate wasting keystrokes. More typing is more errors is more grief. Being an off and on user of Lisp, although not as much as I used to, one of the things that I always liked in Lisp was the ability to be able to return multiple values from a function at once using (values) and then marry that with (multiple-value-bind) to create convenient named bindings for whatever you were about to do. I recently found myself wanting to return a couple of values from a helper function and I just didn't want to go to the trouble of having to type all those character required to create an array with keys for the two values and then I remembered MVB and a little light went on in my head! If somebody else has already done this then I apologise up front but it was new to me and I haven't seen it anywhere else so this could be a first! ...

Angular.JS ... absolutely awesome BUT...

Aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaagh! Sort the documentation soon please!  More soon, I really do like it though. :)

Communicating between controllers in AngularJS

I have seen many solutions to how to make controllers talk to each other whilst at the same time remaining within "da rulez" of writing Angular applications. I have been using Angular for about a month now and at times it has been swearier than a good Haskell session, it is most definitely worth it all in the end. I have written a really nice looking web application for my employer and they seem to like it. I think Angular. One thing I really aced (to my own satisfaction at least) was wrapping a REST (of any type) API using a resource. I will make a separate post about that. Do the simplest thing... Here is my own solution to the problem of how you can make different controllers communicate cleanly using the "event" system that Angular provides. All you have to do is ensure that the following event listener is added to your application root-scope: App.run( function( $rootScope )) { $rootScope.$on('broadcast', function( e, data ) { if (undef...
