Description

This is the main project for various Umple subprojects and components.

Umple is a model-oriented programming technology, allowing developers to embed modelling concepts (e.g. UML associations, state machines), patterns, generation templates, and other abstractions in traditional code, and vice versa. It generates high quality code for Java, C++ and PhP (Python in beta), as well as diagrams, metrics and many other artifacts. It can be embeded in the above languages as well as embed them.

The project homepage is located at https://umple.org/

There are a large number of scientific papers about Umple listed at: https://umple.org/publications

Cite latest software release as: University of Ottawa, Umple, https://umple.org/releases https://doi.org/10.5281/zenodo.4677562 DOI

Releases are created 1-4 times a year, but UmpleOnline always has the latest version.

Development Process

Umple is developed in itself, guaranteeing robustness; the most recent version of the compiler must be used to compile itself. See the wiki for development setup: https://umple.org/devsetup

Development follows a model-driven, test-driven, agile, continuous-integration process. Umple is hosted currently on Github at https://umple.org/code . It was first released in 2007. The master was on Google Code from 2011 to mid 2015 and moved to Github in 2015.

Umple has been largely developed as a research project at the University of Ottawa, Canada, by numerous PhD and masters students. Many undergraduates from across Canada and the USA have also contributed through the UCOSP program. See the license file for the list of contributors. https://umple.org/license

Installation and Downloading

Umple does not need necessarily to be downloaded, the following allow you to run it directly in any web browser:

You can download the java jar for command-line use, or the Eclipse plugin:

  • Download page: https://umple.org/dl - Links to the latest official release and continuous builds (command-line, Eclipse, Docker)

To run locally on your machine, Umple needs Java (versions 8 and up although 17 is recommended) installed. It runs on Mac, Linux and Windows.

Usage

Umple is a programming and modeling language with a rich syntax. Full documentation with many examples can be found at

Other Key links

Umple is continuously tested and built on its own Jenkins server (see https://jenkins.umple.org) . It is also built on Appveyor (https://umple.org/appveyor/).
