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:
More recent net2o version in gforth/site-forth/net2o

BTW: If you have troubles after the update with loading examples: several files moved from gforth/site-forth into gforth//minos2 or -/unix; you might want to delete the entire /sdcard/gforth directory to get rid of the old stuff.

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.

Little left to be desired Since it's gotten pretty stable now, even though I still lose my session after phone went into screen lock. Also, using my phone's standard keyboard in interpreter is nearly impossible, where even backspace doesn't work. Use an alternative one if you can, esp. TAB being a must. Thank you for bringing the Forth into our hands!

Droid RAZR Maxx Been waiting a long time for this. It's bloated, but it does what I need it to.
