A version of the Gambit Scheme system for iPhone/iPod touch/iPad is
now available on the Apple App Store:
“Gambit REPL” is a complete version of Gambit (http://
dynamo.iro.umontreal.ca/~gambit) including the interpreter, debugger
and built-in library (but not the compiler). The standard REPL is
provided and also a script editor. Scripts can be saved, attached to
function keys, and the “main” function of the application can be
redefined to customize the application to your needs. Applications
can be debugged remotely by telneting to the device from a desktop
machine.
The application is sold for $0.99 as a demonstration that you can
distribute on the App Store paid applications written in Scheme and
containing an interpreter, something that wasn’t clear with previous
versions of the App Store developer agreement.
A version of Gambit REPL for Android is not planned (by me). The
Gambit Scheme system compiles fine on Android (for example see
GitHub - seoushi/gambit-android-example: An example project for running Gambit Scheme on android), but the user
interface layer would have to be changed and tested, and I don’t own
an Android device. If someone wants to try porting Gambit REPL to
Android let me know and I can help. The sources of Gambit REPL for
iOS are in the examples/iOS subdirectory of the Gambit source
distribution.
