GNU Forth programming language


Gforth is the GNUs 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.For optimum experience when programming, use a soft keyboard made for that task, like Hackers Keyboard.Gforth is available under GPLv3.Gforth uses GCC to compile a fast direct or indirect threaded Forth; Gforth is fully ANS-Forth and Forth-2012 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.The Gforth apk installs three icons: One is the fast engine (Gforth fast), one the debug engine (Gforth ITC), where the single step debugger works, and the backtrace is precise even on exceptions, and the third one is the net2o protocol demo app, with the "Nettie" octopus. Its a demo now, so dont expect it to work flawless.Fix for Android 12

Editor doesn't work well on my Android 11 tablet. I tried to define a new word from a tutorial example and the interpreter complained that the word I was defining does not exist.

John Moore

Works like a charm on Android 9, but crashes immediately on Android 11. UPD: Thanks, it works now!

Kedru Fubge

Doesn't open; tapped "allow" on file permissions, instantly quits. Shame.

Roswell Grey

Works well, if you understand what Forth is about. There are no ads and no expectation to go pro for a silly fee.

David Harrison

Doesn't work on Samsung Tab A NO more. :( Therd is some problem but now the last version works again.

It works. (1) Would be nice to be able to change font size (2) I can't paste anything into the editor using long press... Also, consider adding options like "Use volume down key for CTRL"; that way, we wouldn't have to install outdated keyboards like Hackers Keyboard, which doesn't work well on all systems.

Alan Squire

last version that works on my android 4.4.4 is from 2018. anything newer just crashes. PLEASE tag new releases as requiring newer android or see about making it work for 4.4

This app creates icon photos in My Photos library. Can't remove the pictures unless remove the app, so I did.

Superb, forth is a wacky language came across it back in the 80s on a commodore 64 , yeah I know. :-) The new versions do not start on any of my devices one device has error that there is no space on device . the Criticism that it is bloated is part because of ANSI spec compliance.

James Andrews

Works well, but very bloated, something that could be said of most GNU software.
