Repository
Prerequisite
Before getting the actual source code you need to get familiar with subversion and its tools. Visit the subversion reference to discover the basics about subversion and the subversion configuration page to configure subversion properly for this project.
Getting the source code
The URL for the repository used to host EiffelStudio's source code is https://eiffelsoftware.origo.ethz.ch/svn/es.
To get all the source code at once simply do:
svn co https://eiffelsoftware.origo.ethz.ch/svn/es/trunk EiffelStudio
This will create a EiffelStudio directory in the directory where the above command was entered.
However to compile EiffelStudio you will have to proceed slightly differently, have a look at the Compiling EiffelStudio page. We will remove this special check out of the code in the near future.
How to get the old releases
The SVN repository also contains the 5.4, 5.5 and 5.6 releases of the EiffelStudio environment. Those versions can only be compiled with an EiffelStudio 5.4, 5.5 and 5.6 release.
The source code can be found in the subdirectories of the branches directory of the svn repository.
