A Controlled Language Programming (CLP) compiler, runtime engine, and development IDE for writing software in a natural (but somewhat restricted) language that clearly represents the real world concerns and maps to a 3GL (Java/Groovy) for execution.
OpenL implements Java-like languages allowing to use code snippets placed in Excel, XML, or DB. OpenL is a foundation for OpenRules http://openrules.com. Maintained from http://openl.org
The compilerMonitor persists a record of all javac error messages and the sources that caused/fixed the errors. It is a CAUSE (computer-aided usability engineering) tool that analyzes interaction between a developer and the compiler.
