Sibyl

The term Sibyl denotes a family of Object Pascal IDEs for OS/2, eComStation and Windows.

Speedsoft Sibyl

The first Sibyl version was Speedsoft Sibyl, which also included a Delphi-like Pascal compiler.

WDSibyl

After being discontinued by Speedsoft, development of Sibyl was resumed by Wolfgang Draxler. WDSibyl contains a Pascal compiler that is an improved version of that of Speedsoft Sibyl. It is available under a GPL license.

Open Sibyl

Another modern Sibyl implementation is Open Sibyl, a RAD IDE that abadonded the Sibyl compiler and replaced it with Free Pascal. Open Sibyl is available as source code under a GPL license.

Significance

Today, all Sibyl implementations have a rather small user base. WDSibyl and Open Sibyl are, however, the only RAD IDEs for Pascal development on and for OS/2 and eComStation (eCS), which are important operating systems for enterprise markets. Sibyl also had a historical impact, since the Megido initiative had the intention to port Speedsoft Sibyl to Free Pascal and to extend its targeting to Linux. While Megido failed it had nevertheless a lasting impact since it was the nucleus of the later highly successful Lazarus project.
