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).
10:
11: Gforth runs under Unix, Win32, MacOS X, OS/2, and DOS and should not
12: be hard to port to other systems supported by GCC. This version has
13: been tested successfully on the following platforms:
14:
15: alpha-dec-osf4.0d
16: alpha-unknown-linux-gnu
17: alphapca56-unknown-linux-gnu
18: hppa1.1-unknown-linux-gnu
19: hppa2.0n-hp-hpux11.00
20: hppa2.0w-hp-hpux11.11
21: i386-unknown-freebsd5.1
22: i686-pc-cygwin
23: i686-pc-linux-gnu
24: mips-sgi-irix6.5
25: mipsel-pc-linux-gnu
26: powerpc-apple-darwin5.4
27: powerpc-unknown-linux-gnu
28: sparc-sun-sunos4.1.4
29: sparc-unknown-linux-gnu
30:
31: Read INSTALL for installation instructions, or INSTALL.DOS for DOS,
32: Windows, and OS/2, or INSTALL.BINDIST if you have a binary package.
33: To start the system, just say `gforth' (after installing it).
34:
35: You can find new versions of Gforth at ftp://ftp.gnu.org/gnu/gforth/
36: and its mirrors or at
37:
38: http://www.complang.tuwien.ac.at/forth/gforth/
39: or
40: ftp://ftp.complang.tuwien.ac.at/pub/forth/gforth/
41:
42: The latter site also contains binary distributions of Gforth for some
43: popular platforms.
44:
45: If you want to work on Gforth, mail me. Tasks to be done can be found
46: in ToDo; but if you would like to do something not mentioned there,
47: it's ok, too. In any case, we would like to hear what you are
48: doing. The most important tasks IMO are the missing ANS Forth words,
49: the documentation and the foreign language interface for C.
50:
51: On popular request, here are the meanings of unusual file extensions:
52:
53: *.fs Forth stream source file (include with "include <file>" from within
54: gforth, or start with "gforth <file1> <file2> ...")
55: *.fi Forth image files (start with "gforth -i <image file>")
56: *.fb Forth blocks file (load with "use <block file> 1 load")
57: *.i C include files
58: *.ds documenation source
59: *TAGS etags files
60:
61: A number of Forth source files are included in this package that are
62: not necessary for building Gforth. Not all of them are mentioned in
63: the rest of the documentation, so here's a short overview:
