[racket] Unload an FFI library

[Dmitry Pavlov]

Hello,

The topic of unloading a library loaded with ffi-lib
was raised in 2010:

http://lists.racket-lang.org/users/archive/2010-August/041023.html

The answer was that Racket can not unload a library.
Has there been any update since then?

Best regards,

Dmitry

No, there's still no support for unloading.

If there were to be support for unloading, is should prorbably be
invoked by the garbage collector.

It would be nice to have at least REloading,
at least "for debugging purposes only" or such.
(also, as far as I understand, reloading brings less
safety issues that unloading). Without the ability
to reload the FFI, it is quite hard to develop a
C library in parallel with Racket code that uses it.
You need to restart DrRacket after each change
in the C library that you want to test in Racket ...

In all other areas -- particularly DSL development --
Racket is the best! I can work on my DSL all the way
incrementally without restarting the IDE.

Best regards,

Dmitry
