Hi all,
After many months of hard work, the Snap team is proud to announce
the release of the next major version of the Snap Framework: Snap
0.3.
New Features
------------
- Snap now has SSL support! To enable SSL support, install the
gnutls library and pass the "gnutls" in when you build
snap-server:
$ cabal install snap-server -fgnutls
- The snap project starter executable has been pulled out of
snap-core and put into its own package, called "snap". The snap
package also contains some library code which the generated
projects make use of, and the generated projects have a simplified
and much cleaner layout.
- Snap now comes with support for working in a "development mode"
which runs your web handlers in an interpreter using the hint
library. This makes working on Snap applications quicker and more
convenient, since you no longer need to perform a
kill/recompile/reload cycle to see your code changes reflected in
your running application.
- One of the new things in the snap package is an experimental
"extensions" mechanism which contains some interfaces/helper code
for writing reusable web components.
- A new MonadSnap typeclass has been defined:
class (Monad m, MonadIO m, MonadCatchIO m, MonadPlus m, Functor m,
Applicative m, Alternative m) => MonadSnap m where
liftSnap :: Snap a -> m a
Most of the basic functions from Snap.Types have been redefined to
accept any monad implementing MonadSnap, and MonadSnap instances
have been defined for most of the standard monad transformers; this
should make it much more convenient to use monad transformers with
Snap without having to use "lift" all over the place.
- Added
getCookie :: MonadSnap m => ByteString -> m (Maybe Cookie), which
allows you to fetch cookies from the request by name.
- Snap now depends on the enumerator package for iteratee support
instead of iteratee.
- The snap-server now has a convenient configuration mechanism
which will parse arguments from the command line for you.
Bugfixes/Improvements
---------------------
- Changed type signature of finishWith from Response -> Snap ()
to Response -> Snap a.
- When using fileServe, file paths are now properly URL-decoded,
meaning you can now download a file with spaces in its name.
- Parameters grabbed by variable capture using route are also now
URL-decoded.
- Under the hood: snap server backend mechanism has been
improved/factored out, making it possible to listen to two or more
ports using different backends at once (e.g. SSL and non-SSL).
Thanks,
G
