gforth - GNU Forth for Android

gforth - GNU Forth for Android


Gforth is the GNU's project implementation of the programming language Forth. This APK is the binary distribution for the Android platform, for ARM and x86-processors. You can find more information and links to source code on http://bernd-paysan.de/gforth.html, and more information about Android-specific features on http://www.forth-ev.de/wiki/doku.php/en:projects:gforth-android:start. Gforth is available under GPLv3.

Gforth uses GCC to compile a fast direct or indirect threaded Forth; Gforth is fully ANS FORTH compliant. Authors of Gforth are Anton Ertl, Bernd Paysan, Jens Wilke, Neal Crook, David Kühling and others.

The goal of the Gforth Project is to develop a standard model for ANSI Forth. This can be split into several subgoals:

* Gforth should conform to the ANSI/200x Forth standard.
* It should be a model, i.e. it should define all the implementation-dependent things.
* It should become standard, i.e. widely accepted and used. This goal is the most difficult one.

To achieve these goals Gforth should be

* Similar to previous models (fig-Forth, F83)
* Powerful. It should provide for all the things that are considered necessary today and even some that are not yet considered necessary.
* Efficient. It should not get the reputation of being exceptionally slow.
* Free.
* Available on many machines/easy to port.

Recent changes:
Most recent snapshot code, most recent net2o.

This also fixes the problem with keyboards like Swype, where the input text is a composite text, and that text wasn't shown before; now you see it in green before it is committed.

Still, using a keyboard dedicated to programming like Hacker's keyboard, or a keyboard with at least some support for cursors and tab (like Go keyboard) is recommended.

A full ANS forth and more on Android, very nice !. Just one feature I would like to add. I would like to use adb to connect to the phone and then have gforth interact with me in that way.

Committed and Organized Programmer I sent Mr. Paysan an email about a difficulty I had installing the latest 5/23/15 version and was amazed to receive a reply within 20 minutes. There is an incredible amount of work that goes into a program like this and an equally incredible amount of knowledge contributed by its programmers. Gforth is one of the best, if not the best open source program available. Don't hesitate to try it, learn from it, and even improve it. A Great Work.

Awesome! Updated review: this is gforth on Android, with an extremely fast OpenGL UI that is written in Forth code that's installed under /sdcard/gfoth/ . I really recommend digging into that code; I've had a lot of fun learning OpenGL with this app. NB. tools to create android apps *with* this app, ala AIDE or Terminal IDE, aren't intended; you'll need to set up a toolchain under some other OS. Also, depending on your hardware, you might not enjoy the console as much (it might aggressively scroll before ever using half of the screen; it might not update the display after each typed character). You might take that as an encouragement to dig into gl-terminal.fs :) If you break it; gforth will unpack the original over it.

Excellent ap Great work Bernd, best forth I've seen for Android. Great for learning Forth in bed at night with "learning forth" pdf open, and switching between them. Thank you, much appreciated.

gforth.on.android. Cannot believe you did this. Thank you, Bernd, most appreciated. Can't wait to throw some code at it.
