| \chapter{Experimental Features} | ||
|
|
||
| The designers of Unicon have taken a very conservative approach when adding to | ||
| the language and when changing existing features. With the small number of | ||
| exceptions that have been previously noted on page \pageref{Unicon-Icon}, an | ||
| Icon program that runs on the final version of Icon (version 9.5, first released | ||
| in 1996) will run on the current Unicon system {\em and give the same results\/} | ||
| a quarter of a century later. The conservative approach is continued when | ||
| dealing with additions to Unicon; breaking existing Unicon programs by making an | ||
| incompatible change to the language is, in most circumstances, considered to be | ||
| a very bad thing to do. | ||
|
|
||
| Most of the development of Unicon starting from it's progenitor has already been | ||
| discussed but there are some more experimental features that are waiting in the | ||
| wings. Some of them may never see the light of day in their present form -- or, | ||
| perhaps, in any form -- so the most cautious approach is not to rely on any of | ||
| them until they make their way from this appendix into the definition of the | ||
| language in Appendix A. | ||
|
|
||
| Without exception, the experimental features are not enabled by default in a | ||
| release build of Unicon -- they can only be accessed by making the appropriate | ||
| pre-processor definitions (or, in some cases, by specifying additional arguments | ||
| to \texttt{configure}) and rebuilding the system from the source code. Some | ||
| features that are now part of the language -- for example, the array extension | ||
| to lists that makes them faster in many cases -- are still guarded by | ||
| pre-processor definitions, showing their pedigree as experimental additions, but | ||
| are now enabled by default. | ||
|
|
||
| %% Candidates for inclusion | ||
| %% | ||
| %% Plugins | ||
| %% User defined operators | ||
| %% UTF-8 | ||
| %% Extensions to &random | ||
|
|
||
| \section{User defined operators} | ||
| This feature extends the syntax of classes to allow the built-in operator | ||
| symbols to be redefined when their operands are objects. It may be enabled by | ||
| using the \texttt{-{}-enable-ovld} option to \texttt{configure} before | ||
| rebuilding the Unicon system. | ||
|
|
||
| \section{Extensions to \texttt{\&random}} | ||
| This feature allows the programmer to choose from a portfolio of different | ||
| random number generators (in addition to the one provided by Icon). It is also | ||
| possible to implement other generators and use them without rebuilding Unicon. | ||
| More than one generator may be in use at the same time. | ||
| It may be enabled by defining the C preprocessor symbol \texttt{RngLibrary} | ||
| before rebuilding the Unicon system. |
