Haskell support for Eclipse

It would probably be possible, but you need to have Cabal configured
with your proxy outside of EclipseFP, don't you? For example, we don't
run "cabal update" for you, we just recommend to do it before
installing scion. If your cabal is configured to use your proxy, will
the scion install work properly?

Hi JP,

Sorry for the missing subject ;-)

this was my solution: configure the proxy for cabal outside of eclipse. And it works now.
I think this feature makes eclipse-fp wokring for more people out-of-the-box, especially for haskell beginners like me.

Thanks

Ok, done. It will appear in 2.0.3. If you have a proxy defined in
Eclipse that would be used by Eclipse to access
http://hackage.haskell.org, then cabal install scion will use it,
through the HTTP_PROXY environment variable.

Sorry for the late reply into this discussion. It's an impedance mismatch between a Unix and Win32 environment, I'm guessing. KDE and Gnome handle setting the environment for you (mostly), whereas the Win32 API deals with proxies differently and you really need to use the API. That doesn't help for a Unix-based program like cabal-install.

I'm sure that JP just hacked in support for HTTP_PROXY, although http_proxy seems to be more common. Might want to beg the Cabal maintainers to consider supporting the Win32 API to avoid these issues in the future.

Bug/misfeature I can think of and need to test: Win32 eclipse doesn't store or prompt for pass if needed. Might cause interesting bug reports for people behind authenticating proxies, where the proxy password changes daily (hint: this confirms that there's a real user at the keyboard.)

BTW it's a misfeature of Java, not windows.

Huh? Cabal-install deals fine with proxies defined in Windows. I have
a machine that uses a proxy and don't have any issue. Klaus' issue is
that if you have NOT defined your proxy at your OS level, but at the
Eclipse level, we ignore it. Hence, the changes I made reads the
Eclipse information and if it is set passes it to Cabal using the
documented Cabal parameters.

Hmmm... I'm not entirely sure that I'm totally off base. I'll test on Monday when I'm behind the corporate firewall.

Hi,

I think it would be a nice feature if EclipseFP automatically installs a missing package on adding it to a project.
