Maybe you know it, maybe you don’t but yUML is awesome!

Create and share simple UML diagrams in your blogs, wikis, forums, bug-trackers and emails.

Yesterday I was creating a new class diagram using yUML and besides it’s a great product it was a bit cumbersome working in a small textarea and pressing ‘Generate!’ (all the time). I fired up textmate and created a diagram using the yUML syntax. A couple of minutes later I had ruby script which generated the diagram using yUML by taking a text file as input.

Thanks to Jeweler it’s dead easy to create gems and release them to Gemcutter so a yumlcmd gem was born.

###Installation###

sudo gem install yumlcmd

###Usage###

yumlme -f your-diagram.txt

###Example your-diagram.txt###

[Customer]+1->*[Order]

[Order]++1-items >*[LineItem]

[Order]-0..1>[PaymentMethod]

Syntax overview: http://yuml.me/diagram/scruffy/class/draw

###Output###

I hope you like it as much as I do :)
