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 and a powerful locals
4: facility, and it even has a manual. Gforth employs traditional
5: implementation techniques: its inner innerpreter is indirect or direct
6: threaded. Gforth is distributed under the GNU General Public license
7: (see COPYING).
9: Gforth runs under Unix, Win95, OS/2, and DOS and should not be hard to
10: port to other systems supported by GCC. This version has been tested
11: successfully on the following platforms:
29: Read INSTALL for installation instructions, or INSTALL.DOS for DOS,
30: Windows 95, and OS/2. To start the system, just say `gforth' (after
31: installing it).
33: You can find new versions of Gforth at ftp://ftp.gnu.org/gnu/gforth/
34: and its mirrors or at
40: The latter site also contains binary distributions of Gforth for some
41: popular platforms.
43: If you want to work on Gforth, mail me. Tasks to be done can be found
44: in ToDo; but if you would like to do something not mentioned there,
45: it's ok, too. In any case, we would like to hear what you are
46: doing. The most important tasks IMO are the missing ANS Forth words,
47: the documentation and the foreign language interface for C.
49: On popular request, here are the meanings of unusual file extensions:
51: *.fs Forth stream source file (include with "include <file>" from within
52: gforth, or start with "gforth <file1> <file2> ...")
53: *.fi Forth image files (start with "gforth -i <image file>")
54: *.fb Forth blocks file (load with "use <block file> 1 load")
55: *.i C include files
56: *.ds documenation source
57: *TAGS etags files
59: A number of Forth source files are included in this package that are
60: not necessary for building Gforth. Not all of them are mentioned in
61: the rest of the documentation, so here's a short overview:
64: code.fs random.fs more.fs ansi.fs colorize.fs
65: oof.fs oofsampl.fs objects.fs blocked.fb tasker.fs
68: ans-report.fs etags.fs glosgen.fs filedump.fs
71: tt.fs sokoban.fs
73: Test programs (for testing Forth systems):
77: bubble.fs siev.fs matrix.fs fib.fs
79: ANS Forth implementations of Gforth extensions:
80: compat/*.fs other.fs
