New! July 24, 2009: At long last, we solved a set of related install issues that resulted from some errors in our feature meta-data (see the mailing list for details, if you are interested). Those errors manifested in various ways: as an inability to install IMP, an inability to update IMP, or an inability to install other (even unrelated) components after installing IMP, and the like. IMP should now install cleanly under Eclipse 3.5, 3.4, or 3.3.
IMP was previously available on an update site on SourceForge.net. This site is exceedingly old, and no longer kept up to date. We expect to remove that site sometime soon.
If you will be using LPG, you will also need the LPG generator and runtime features. The
former includes the LPG generator executable and the associated templates needed to build
parsers and lexers from their specification files. The latter
contains the LPG Java runtime library.
New! 25 March 2009: Both of these features are now available through the IMP update site.
To create formatting specifications for a language editor in an IMP IDE you will also need the Syntax Definition Formalism (SDF) plug-ins.
New! 25 March 2009: This feature is now available through the IMP update site.
X10 is an adaptation of Java with extensions to support parallel programming. If you are interested in working
