rpglepp is a preprocessor for the ILE RPG language,
also known as RPG IV. It is written in Java with the help of the ANTLR parser generator.
The main use case for rpglepp is to handle conditionals and perform copybook inclusion in order to
obtain the exact source that a proper RPG parser would process. This may be saved to a file or fed to
such a parser.
Originally rpglepp was developed to be used in conjunction with the rpgleparser
ILE RPG parser, but the project has since diverged. The rpgleparser-compatible branch tracks the
last version that followed rpgleparser, but is not being actively maintained.
rpglepp is available from the Maven Central repository.
