Portable Forth Environment Description

ANSI Standard for Forth based environment Portable Forth Environment (or PFE for short) is based on the ANSI Standard for Forth. The PFE has been created by Dirk-Uwe Zoller and had been maintained up to the 0.9.x versions (1993-1995). Tektronix has adopted the PFE package in 1998 and made a number of extensions.It is now fully multithreaded and it features a module system. You can load additional C objects at runtime to extend the Forth dictionary. It is best targeted for embedded environments since you can easily exchange the terminal driver and the initialization routines.Design objectivesCORRECTthis means not just "no bugs" -- it means all the interaction of all parts works as specified by the standard.TRADITIONALand beyond the standard, it shall behave in tradional ways to allow to easily adapt sources from older forth systems to the PFE.COMPLETEwith powerful computers on the desk and powerful programming environments there is no need to and no use in strategies like "here kernel, there xyz word set" that might be appropriate on a microcontroller.PORTABLEI hate to rewrite code because of environmental dependencies. The PFE uses autoconf/automake for automatic system detection, and its drivers for system interaction are largely seperated out.USABLEA sole kernel helps noone. It should be a development environment. You should be able to manage multiple-source-file-projects from within. A source debugger and help files are included of course.SIMPLEor transparent. At least to my taste. The coding style should make it easy to pick up PFE and adapt it to whatever environment it shall run in.MODULARit allows to add extensions during runtime. There is no need to rebuild the PFE core for each different application, the main runtime can be shared and extended with extra modules.FREEapart from being free of cost, the PFE is given away under LGPL (not the GPL!) which allows you to add dynamic extra modules under whatever copyright you wish to, even commercial ones. No GPL virus here.OPENand if you have a nice extra module then I am open to ship it along and to provide it with whatever hooks are needed in the LGPL core. What's New in This Release: · This is mostly a bug fix release. It does also feature updates to dstrings, an extended testsuite, forth200x extension queries, removal of pfe-config.
