## Language support and libraries
|

Vishap Oberon supports the Oberon 2 programming language, including type-bound procedures.
|
||||
Vishap Oberon supports the Oberon 2 programming language, including type-bound procedures. SYSTEM.Mod includes additional functionality and some changes for 64 bit support.
|
||||
|

It also supports some features of Oberon-07.
|
||||
##### Integer and set type sizes:
|
||||
|
||||
Vishap Oberon comes with libraries easing the porting of code from the major
|
||||
Oberon systems:
|
||||
| Type | -O2 option (default) | -OC option |
|
||||
| --- | --- | --- |
|
||||
| SHORTINT | 8 bit | 16 bit |
|
||||
| INTEGER | 16 bit | 32 bit |
|
||||
| LONGINT | 32 bit | 64 bit |
|
||||
| SET | 32 bit | 64 bit |
|
||||
|
||||
##### Libraries
|
||||
|
||||
Included libraries ease porting of code from the major Oberon systems:
|
||||
|
||||
- Oberon V4 and S3 compatible library set.
|
||||
|
||||
- ooc (optimizing oberon-2 compiler) library port.
|
||||
|
||||
- Ulm’s Oberon system library port.
|
||||
- Okwood standard libraries.
|
||||
- Some other freely redistributable libraries.
|
||||
|
||||
Oakwood libraries are supported for both -O2 and -OC options, whereas the ULM, OOC and ETH system 3 libraries are only available on -O2 (default) compilations.
|
||||
|
||||
|
||||
Vishap Oberon also supports some features of Oberon-07.
|
||||
|
||||
Some other freely redistributable libraries are available as a part of voc distribution.

## Contributors

Originally developed as a cross platform implementation of the
|
||||
Oberon system by Joseph Templ.
|
||||
Joseph Templ developed ofront as a tool to translate Oberon-2 programs into semantically equivalent
|
||||
C programs. It was Copyrighted in 1995, and transferred to the Free BSD license in 2012.
|
||||
|
||||
Updated for 64 bit support, refactored as a standalone compiler and brought
|
||||
to new platforms by Norayr Chilingarian.
|
||||
From Joseph's github repository:
|
||||
|
||||
Build process simplified for more platform support and bugs fixed by David
|
||||
C W Brown.
|
||||
> Design and implementation of ofront is due to Josef Templ ... ofront has been based in part on Regis Crelier's PhD thesis and Stefan Gehring's diploma thesis, both at ETH Zurich, Institute for Computer Systems.
|
||||
|
||||
Norayr Chilingarian forked ofront in 2013, porting extensive libraries from [ULM Oberon](http://www.mathematik.uni-ulm.de/oberon/), [OO2C](https://github.com/Spirit-of-Oberon/oo2c) and ETH Oberon System 3, and adding support for more platforms including 64 bit systems, and .
|
||||
|
||||
David Brown has worked on adding support for more platforms incuding windows using MSC, cygwin or mingw since January 2016. More recently he has generalised basic type support within the compiler to allow e.g. 64 bit LONGINT on 32 bit systems, and 32 bit LONGINT on 64 bit systems.

## Origin of the name "Ѵishap Oberon"
|
||||
|
||||
###### Ѵishap
|
||||
|
||||
Vishaps are dragons inhabiting the Armenian Highlands.
|
||||
We decided to name the project “Vishap” because ties between compilers and dragons have ancient traditions.
|
||||
|
||||
Also, Vishaps are known in tales, fiction. [This page](http://blog.fogus.me/2015/04/27/six-works-of-computer-science-fiction/) refers to some technologies as “computer science fiction”. Among them to Oberon. This brings another meaning, Oberon is like aliens, ghosts. And Vishaps.
