repl for android

[Sonny To]

One thing I like about Clojure for Android is the repl. Is there a
repl for android where I can attach from emacs and eval some code and
dynamically construct a UI?

Kawa does includes a telnet server. You could start it on the phone with:
java kawa.repl --port PORTNUM
where PORTNUM is the listening port. (If you use 0, an available port is used.)

Then from your PC you can telnet to that port:

telnet IPADDR PORTNUM

where IPADDR is that of your Android device.

I haven't tested this with an Android device. Of course note that telnet
is unencrypted and insecure, so don't use an unencrypted WiFi connection.

Better, but more complex, would be to use a ssh server on the device.

Kawa's eval/repl on Android does have some limitations because you can't
construct new classes on the fly. (On other targets repl/eval code is
first compiled to bytecode before it is executed. That is not an option
on Android at this time.)

Oops - that should have been

java kawa.repl --server PORTNUM

The ---port flag used used to start a http server, while the --server flag
is used to start a telnet server.
