Steve,
maybe I can help.
##decompile retrieve the source code of a procedure (if
available):
> (##decompile (##lambda () test))
(lambda () test)
If you change the name-space with:
> (namespace ("test-namespace#"))
decompile yields:
> (##decompile (##lambda () test))
(lambda () test-namespace#test)
That means you have to strip the symbol suffix `test`
to get the name-space.
If you use the empty symbol, denoted by ||, you get the name-space
symbol directly:
> (##decompile (##lambda () ||))
(lambda () test-namespace#)
With this information, one can define the following macro:
> (define-macro (##current-namespace) (##symbol->string (eval
(##quote (##caddr (##decompile (##lambda () ||)))))))
For e newly started gsi you get:
>
(##current-namespace)
""
If you change the name-space you get:
> (namespace ("test-namespace#"))
>
(##current-namespace)
"test-namespace#"
HTH,

Marc,
Could you explain this a bit?

Subject: Re: [gambit-list] Current namespace at the repl
A bit of a hack... Try:
(##caddr (##decompile (##lambda () ||)))
You can define a macro based on that idea.

Is there a function (or would it be easy to access the internals to write one) to find out what the currently active namespace is at the repl. Ie after entering a few (namespace ("foo#")) expressions it would be nice to be able check what the current namespace is with eg (current-namespace) --> "foo#"
Thanks
Duncan
