Converting Markdown To HTML; In Any Mac Text Editor (With A Little Help From Automator)
There must be a truism somewhere out on the interwebs that goes something like this ...
if a computer geek finds himself or herself doing a task repeatedly, he or she will invariably find a way to automate this task
... and if there isn't a truism to this effect, then I've just written it for the first time.
In this particular case, the repetitive task was converting text written using John Gruber's Markdown syntax into HTML. Those of you who know Markdown will be asking the question "but Markdown is already a text-to-HTML conversion tool, why would you want to do this?". They'd be right too, so an explanation is due.
