Oubliette

Introduction

Oubliette is the Mesham compiler line from version 1.0 onwards. This line is completely rewritten from the previous Arjuna, using lessons learned and the fact that the language has reached a stable state in terms of definition and the type oriented approach.

Implementation

Oubliette is written in C++ and uses Flex for tokenisation and Bison for parsing. The type library is entirely separate and it is intended in the future to support extra libraries via dynamic libraries. Unline Arjuna, which has the standard function library hard coded in the compiler, Oubliette just considers these to be normal Mesham source code files which are included by the programmer. This approach gives increased flexibility and a cleaner compiler.

All the types have been entirely rewritten and an API (documentation to follow) has been created to allow for third party extensions.

Idaho

To support this new version of the compiler, the runtime library has been reengineered and released under the name Idaho. This version supports the functionality required by Mesham, the standard library and some internal housekeeping work.
