MLWorks is a compiler and interactive development environment for the Standard ML language, developed by Harlequin in the 1990s and now owned by Ravenbrook Limited.

The main project page is at http://www.ravenbrook.com/project/mlworks/

MLWorks does not currently build. The compiler is written in Standard ML and should be easy to bootstrap. The run-time system is a mixture of C and assembler but is neither large nor complicated, and should be easy to port. Get involved!

IMPORTANT: This is a temporary Git repository starting at the latest revision of the MLWorks sources, and does not include the full version history. This repository will be replaced by one with a full history, and any work will need to be migrated. Please consider this before cloning or forking.

MLWorks is a commercially developed "industrial strength" ML development system, developed by Harlequin in the 1990s. Harlequin broke up in 1998, and MLWorks became property of Xanalys Limited. Ravenbrook Limited (whose directors were members of the original MLWorks team) acquired the rights to MLWorks on 2013-04-26 and open sourced the project.

Ravenbrook would like to thank Xanalys, and especially Paul Miller, for being both willing and generous to help with the open source publishing of this work.
