1: Gforth is a fast and portable implementation of the ANS Forth
2: language. It works nicely with the Emacs editor, offers some nice
3: features such as input completion and history, backtraces, a
4: decompiler and a powerful locals facility, and it even has a
5: manual. Gforth combines traditional implementation techniques with
6: newer techniques for portability and performance performance: its
7: inner innerpreter is direct threaded with several optimizations, but
8: you can also use a traditional-style indirect threaded interpreter.
9: Gforth is distributed under the GNU General Public license (see
12: Gforth runs under Unix, Win95, OS/2, and DOS and should not be hard to
13: port to other systems supported by GCC. This version has been tested
14: successfully on the following platforms:
32: Read INSTALL for installation instructions, or INSTALL.DOS for DOS,
33: Windows 95, and OS/2, or INSTALL.BINDIST if you have a binary package.
34: To start the system, just say `gforth' (after installing it).
36: You can find new versions of Gforth at ftp://ftp.gnu.org/gnu/gforth/
37: and its mirrors or at
43: The latter site also contains binary distributions of Gforth for some
44: popular platforms.
46: If you want to work on Gforth, mail me. Tasks to be done can be found
47: in ToDo; but if you would like to do something not mentioned there,
48: it's ok, too. In any case, we would like to hear what you are
49: doing. The most important tasks IMO are the missing ANS Forth words,
50: the documentation and the foreign language interface for C.
52: On popular request, here are the meanings of unusual file extensions:
54: *.fs Forth stream source file (include with "include <file>" from within
55: gforth, or start with "gforth <file1> <file2> ...")
56: *.fi Forth image files (start with "gforth -i <image file>")
57: *.fb Forth blocks file (load with "use <block file> 1 load")
58: *.i C include files
59: *.ds documenation source
60: *TAGS etags files
62: A number of Forth source files are included in this package that are
63: not necessary for building Gforth. Not all of them are mentioned in
64: the rest of the documentation, so here's a short overview:
67: code.fs random.fs more.fs ansi.fs colorize.fs
68: oof.fs oofsampl.fs objects.fs blocked.fb tasker.fs
71: ans-report.fs etags.fs glosgen.fs filedump.fs
74: tt.fs sokoban.fs
76: Test programs (for testing Forth systems):
80: bubble.fs siev.fs matrix.fs fib.fs
82: ANS Forth implementations of Gforth extensions:
83: compat/*.fs other.fs
