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: its inner
7: interpreter is direct threaded with several optimizations, but you can
8: also use a traditional-style indirect threaded interpreter. Gforth is
9: distributed under the GNU General Public license (see COPYING).
11: Gforth runs under Unix, MS Windows, MacOS X, OS/2, and DOS and should
12: not be hard to port to other systems supported by GCC. This version
13: has been tested successfully on the following platforms:
31: Read INSTALL for installation instructions from source, or INSTALL.DOS
32: for DOS, Windows, and OS/2 from source, or INSTALL.BINDIST if you have
33: a binary package distributed as .tar.gz or .zip file. If you received
34: a self-installing executable, just run it and follow the instructions.
36: To start the system, just say `gforth' (after installing it).
38: You can find new versions of Gforth at ftp://ftp.gnu.org/gnu/gforth/
39: and its mirrors or at
45: The latter site also contains binary distributions of Gforth for some
46: popular platforms.
48: If you want to work on Gforth, mail me. Tasks to be done can be found
49: in ToDo; but if you would like to do something not mentioned there,
50: it's ok, too. In any case, we would like to hear what you are
51: doing. The most important tasks IMO are the missing ANS Forth words,
52: the documentation and the foreign language interface for C.
54: On popular request, here are the meanings of unusual file extensions:
56: *.fs Forth stream source file (include with "include <file>" from within
57: gforth, or start with "gforth <file1> <file2> ...")
58: *.fi Forth image files (start with "gforth -i <image file>")
59: *.fb Forth blocks file (load with "use <block file> 1 load")
60: *.i C include files
61: *.ds documenation source
62: *TAGS etags files
64: A number of Forth source files are included in this package that are
65: not necessary for building Gforth. Not all of them are mentioned in
66: the rest of the documentation, so here's a short overview:
69: code.fs random.fs more.fs ansi.fs colorize.fs
70: oof.fs oofsampl.fs objects.fs blocked.fb tasker.fs
73: ans-report.fs etags.fs glosgen.fs filedump.fs
76: tt.fs sokoban.fs
78: Test programs (for testing Forth systems):
82: bubble.fs siev.fs matrix.fs fib.fs
84: ANS Forth implementations of Gforth extensions:
85: compat/*.fs other.fs
