foldr on ElemsView is defined as such:
foldr f i (ElemsView c) = foldr (f . snd) i c
so, for example:
getElementList = toList . ElemViews
When I designed this code (some years ago), I didn't like the fold of Map to
have the type:
fold :: (a - b - b) - b - Map k a - b
This just doesn't
Hello folks,
Prompted by Ashley's proposal for Category class, I came up with the following
module, which gives a summary of the overloading situation in the base package.
Maybe it can help people find their way through all the available names...
Failing that it surely was fun to come up with. :)
Can you explain why you could not use the parsec name,
with revision number (say) 2.2?
This would help improve hackage/cabal/... versioning mechanism.
Thanks,
JP.

Hi,
could I ask you for efficient StringMap implementations, i.e. based on
tries or hash keys? It's mainly for the sake of interest. In the (not

along the lines of Data.Map

Hello,
I have modified the Alex lexer generator to support unicode.
The general idea is that the state-machine works on the UTF8
representation of the text. I submit my work here for review
in order to off-load the maintainer (Simon Marlow) as far
as possible.

Hi Jean-Philippe,
Using cabal install:
cabal install yi-0.4.1
when I do this on my Windows machine, cabal-install tries to download
the unix-2.3.0.0 package, which clearly won't work. How do I get yi to
install on Windows?

Consistently on x64. The pango stuff is generally unstable anyway. I'm not sure
what's to blame.

Maybe you could ask Krasimir Angelov, which did the win32 port.

Yep; I think this is fixed in later GHCs.

I think it would be worth spending some time (on this mailing list,
perhaps, or in another forum) trying to hash out a decent API which
meets most people's requirements, rather than ending up with 4 or 5
slightly different ones.
Indeed. I have my own version here:

This is just fixed in the darcs repo.
The custom file yi-i386-linux does not exist and I don't have
any idea what that is.
Yi tries to compile your config file as it starts. It was

You can install the cabal packages for everyone (ie. dropping --user)

copy it into every directory.

I am Yi maintainer, and therefore responsible for this mess :)
The Yi build is rather involved (due among others to its dynamic nature), and to
make things worse, the build procedure is not up to date. I'm working on
simplifying things though.

OK, got the builds to work. I did, in fact, have to go two layers down to

My take:
Blacklisting equals releasing a bugfix.
Using version number conventions, identifying such a release should be easy.
If there exists a bugfix release for a package currently in use, then cabal
should emit a warning.

Not quite.
I propose to *define* blacklisting as such.
package-X.Y.Z.W is blacklisted if there exists package-X.Y.Z.V
