gforth Documentation

Some Fossies usage hints in advance:

  1. To see the Doxygen generated documentation please click on one of the items in the steelblue colored "quick index" bar above or use the side panel at the left which displays a hierarchical tree-like index structure and is adjustable in width.
  2. If you want to search for something by keyword rather than browse for it you can use the client side search facility (using Javascript and DHTML) that provides live searching, i.e. the search results are presented and adapted as you type in the Search input field at the top right.
  3. Doxygen doesn't incorporate all member files but just a definable subset (basically the main project source code files that are written in a supported language). So to search and browse all member files you may visit the Fossies gforth-0.7.3.tar.gz contents page and use the Fossies standard member browsing features (also with source code highlighting and additionally with optional code folding).
README
Gforth is a fast and portable implementation of the ANS Forth
language. It works nicely with the Emacs editor, offers some nice
features such as input completion and history, backtraces, a
decompiler and a powerful locals facility, and it even has a
manual. Gforth combines traditional implementation techniques with
newer techniques for portability and performance: its inner
interpreter is direct threaded with several optimizations, but you can
also use a traditional-style indirect threaded interpreter.  Gforth is
distributed under the GNU General Public license (see COPYING).

Gforth runs under GNU, BSD, and similar systems, MS Windows, MacOS X,
OS/2, and DOS and should not be hard to port to other systems
supported by GCC. This version has been tested successfully on the
following platforms:

Read INSTALL for installation instructions from source, or INSTALL.DOS
for DOS, Windows, and OS/2 from source, or INSTALL.BINDIST if you have
a binary package distributed as .tar.gz or .zip file.  If you received
a self-installing executable, just run it and follow the instructions.

To start the system, just say `gforth' (after installing it).

You can find new versions of Gforth at ftp://ftp.gnu.org/gnu/gforth/
and its mirrors or at

http://www.complang.tuwien.ac.at/forth/gforth/
or
ftp://ftp.complang.tuwien.ac.at/pub/forth/gforth/

The latter site also contains binary distributions of Gforth for some
popular platforms.

If you want to work on Gforth, mail me. Tasks to be done can be found
in ToDo; but if you would like to do something not mentioned there,
it's ok, too. In any case, we would like to hear what you are
doing. The most important task IMO is the foreign language interface
for C.

On popular request, here are the meanings of unusual file extensions:

*.fs	Forth stream source file (include with "include <file>" from within
        gforth, or start with "gforth <file1> <file2> ...")
*.fi	Forth image files (start with "gforth -i <image file>")
*.fb	Forth blocks file (load with "use <block file> 1 load")
*.i	C include files
*.ds	documenation source
*TAGS	etags files

A number of Forth source files are included in this package that are
not necessary for building Gforth. Not all of them are mentioned in
the rest of the documentation, so here's a short overview:

Add-ons:
code.fs random.fs more.fs ansi.fs colorize.fs
oof.fs oofsampl.fs objects.fs blocked.fb tasker.fs

Utilities:
ans-report.fs etags.fs glosgen.fs filedump.fs

Games:
tt.fs sokoban.fs

Test programs (for testing Forth systems):
test/*.fs

Benchmarks:
bubble.fs siev.fs matrix.fs fib.fs

ANS Forth implementations of Gforth extensions:
compat/*.fs
