Omelette is a language dedicated to describe UML diagrams. Currently we support only class and use case diagrams, but the language and compiler are designed to be extensible.

Omelette consists of three parts:

1. Omelette - Language used to describe UML diagrams
2. Fromage - Simple IDE for editing, generating and exporting diagrams.
3. cli - command line compiler of Omelette

Omelette requires pyQT and pyparsing.

Although it's not required, we encourage you to install pygraphviz. We offer two built-in layout algorithms, but they aren't very impressive.

Currently there's no such thing.

If you speak polish you can read our report. You will find the manual and semi-formal description of language syntax there.

class Student
  +learn(stuff)

class University

association
    source-object : Student
    target-object : University 

prototype class course
    stereotype : "course"

course Course

course compSci
    name : "Computer Science"
    +code()

course Art
    +dance()
    +paint()
    +play()

prototype generalisation is_crs 
    target-object : Course 

is_crs
    source-object : compSci
is_crs
    source-object : Art

This compiles to:

As you can see, the language is pretty powerful. This example covers some features of Omelette:

1. classes, and different types of relations (currently we also support notes, use cases, actors, and other types of relations)
2. properties and operations (we also support attributes)
3. prototyping (objects compSci, Course and Art inherit stereotype from course; There are also two anonymous is_crs objects, which inherit theirs target object from is_crs).
