Helium is a functional programming language (a subset of Haskell) and a compiler designed especially for teaching. The main developers and initiators are Arjan van IJzendoorn, Rijk Jan van Haaften, Bastiaan Heeren and Daan Leijen. Currently, Jurriaan Hage, and Bastiaan Heeren maintain the compiler and associated tools. For more information about Helium contact us.
Helium and the runtime lvmrun are on Hackage. This means that you can install the latest version of Helium by running
cabal install helium
cabal install lvmrun
The former of the two is the compiler (which will probably install a few more packages, like Top and lvmlib), the second is the run-time. You can then test the installation by running the program texthint and evaluating a few expressions.
Other kinds of downloads are not supported anymore, and we advise against using them.
Helium 1.8.1 and higher again have support to work with the graphical Java-based programming environment Hint, originally developed by Arie Middelkoop.
Download the Hint 1.8.1 jar file
The program can be run from the command line in the usual way
java -jar Hint-1.8.1.jar
Of course, you must have the Java runtime installed on the system. Note that you need Hint version 1.8.1 or higher for this to work.
Hint is not available through Hackage. The sources of Hint are publicly available from the github repository that also stores the source code of the Helium compiler and all associated tools.
All software associated with Helium is available from a publicly available git repository at https://github.com/Helium4Haskell/, in particular the repositories
These source distributions are to be used at your own risk.
- making Helium full Haskell 2010 compliant
- check documentation consistency
- performance bug fix type inferencer
