Get Homebrew installed on your mac if you don't already have it
Install highlight. "brew install highlight". (This brings down Lua and Boost as well)
## fix "Waiting for other installations to complete." on OSX 10.6 10.7 | |
## sometimes a failed installation leaves us unable to | |
## perform an installation. The following fixes it for me | |
sudo rm /private/var/db/mds/system/mds.install.lock | |
sudo reboot |

When using directives, you often need to pass parameters to the directive. This can be done in several ways. The first 3 can be used whether scope is true or false. This is still a WIP, so validate for yourself.

Last week I had a crash course in PureScript - a Haskell-like language that compiles to JavaScript. I’m not about to preach that you should write your web apps in Haskell (though I strongly recommend learning Haskell), however, I do wish to explore an important part of any Functional Programming language that has eluded Javascript...
There is a lot to be said about Javascript and its lack of static typing. We’ve built the whole web with it! But this post will explore the benefits of a compile-time strong static type system.
