Re: [Haskell-cafe] ByteString install issues with GHC 7.0.3 on Windows 7
Resolved my problems by going after later versions of ByteString:
>cabal install bytestring-0.9.2.0
Resolving dependencies...
cabal: bytestring.cabal:70: The 'type' field is required for test suites.
The
available test types are: exitcode-stdio-1.0
cabal: Error: some packages failed to install:
bytestring-0.9.2.0 failed during the configure step. The exception was:
ExitFailure 1
That did not work, but the following:
>cabal install bytestring-0.9.1.10
Resolving dependencies...
No packages to be installed. All the requested packages are already
installed.
If you want to reinstall anyway then use the --reinstall flag.
tells me that I already had a working version. I was chasing the wrong
problem.
Looking at my BlazeHtml code again, there were imports declared as follows:
> import Prelude hiding (head, id, div)
> import Text.Blaze.Html4.Strict as H hiding (map)
> import Text.Blaze.Html4.Strict.Attributes as A
> import Control.Monad
> import Data.Monoid (Monoid, mappend, mempty, mconcat)
> import Text.Blaze.Renderer.Utf8 (renderHtml)
> import Data.ByteString.UTF8 as B
The last import was the problem. Something changed in the libraries to make
this 'UTF8' line break. I worked around this for now.
Need to research some more, quick glance at the bytestring library versions
suggest 'Char8' not 'UTF8' . However Data.ByteString.UTF8 is in the
utf8-string-0.3 library
(http://hackage.haskell.org/packages/archive/utf8-string/0.3/doc/html/Data-B
yteString-UTF8.html).
So my question becomes "Can someone tell me if there are notes somewhere on
the state of play of the UTF8 ByteString Libraries"

Subject: [Haskell-cafe] ByteString install issues with GHC 7.0.3 on Windows
7
This morning I was successfully running BlazeHtml on Windows 7. Then I
installed some libraries from other packages and BlazeHtml broke.
I then decided to go from ghc 6.12.1 to ghc 7.0.3 and reinstall everything.
BlazeHtml installed OK. But my program also needed ByteString. So I did the
following:
First I tried the stable version:

E.g. {-# LANGUAGE RecordPuns, Generics #-}

I am not experienced enough to fix this, so I tried a previous ByteString
version:

No joy.
Help appreciated.
May try all this on my MAC tomorrow.

It's not the library, it's runhaskell ./Setup.hs ... versus cabal install The previous defaults to global installs, the latter to user installs. So you can either - run cabal install in the package directory (if you don't give a package name to install, it installs [tries to install] the package from the current directory) - pass the --user flag to runhaskell ./Setup.hs, runhaskell ./Setup.hs configure --user --prefix=C:\Users\Ralph\...

RE: [Haskell-cafe] Installing Curl on Windows 7 - no longer a permissions problem - due to dependency conflicts
Permissions issue was straight-forward to resolve. Yesterday I tracked this down to a conflict with versions of bytestring. ghc.6.10.4 needs bytestring-0.9.1.4 ghc-pkg: unregistering bytestring-0.9.1.4 would break the following packages: ha ddock-2.4.2 ghc-6.10.4 Win32-2.2.0.0 regex-base-0.72.0.2 regex-posix-0.72.0.3 re gex-compat-0.71.0.1 zlib-0.5.0.0 HTTP-4000.0.6 cgi-3001.1.7.1 curl-1.3.5 QuickCh eck-2.1.0.3 tagsoup-0.9 feed-0.3.7 tagsoup-0.10 utf8-string-0.3.6 xml-1.3.7 (use --force to override) other libraries need bytestring-09.1.6 ghc-pkg: unregistering bytestring-0.9.1.6 would break the following packages: Wi n32-2.2.0.0 Win32-2.2.0.2 HTTP-4000.0.9 (use --force to override) Yesterday I could not access haskell.org to see if I can install a newer version of GHC - network or server is done.

My change notes have this being a change between 0.6 and 0.8. As Malcolm says, any old uses of "Tag" should become "Tag String". The reason is that Tag is now parameterised, and you can use Tag ByteString etc. However, I should point out that Tag ByteString won't be any faster than Tag String in this version (it's in the future work pile). >> > Forgot to add: I now need to understand the following warnings on this >> > line "> import Text.HTML.Download": Everyone's comments have been right. I previously included Text.HTML.Download so that it was easy to test tagsoup against the web. Since I first wrote that snippet the HTTP downloading libraries have improved substantially, so people should use those in favour of the version in tagsoup - you'll be able to connect to more websites in more reliable ways, go through proxies etc. I don't intend to remove the Download module any time soon, but I will do eventually.

You could go to the Haskell folder, and grand your current user full rights, but any new tools installed will inherit the original and not modified permission (I believe). The other approach I like much better is instead of doing global installs, do user installs. In fact, I made it my default. Which solves any permission error, but means every user on that machine has to install the libs separately which shouldn't be a problem if you're the only one. To do this go to C:\Users\\AppData\Roaming\cabal\ and open the file "config" in a text editor and inside that, uncomment the bit that says "user-install: True" That should do it.

[Haskell-cafe] Windows 7 Permission Denied Problem on Cabal
Following a successful install of the Haskell Platform on MAC OSX, I proceed to update my Windows PC. Frustration followed. I am blocked by a "Permission Denied" error when I do a "Setup install": >ghc --make Setup [58 of 58] Compiling Main ( Setup.hs, Setup.o ) Linking Setup.exe ... >Setup configure Configuring Cabal-1.8.0.4... >Setup build Preprocessing library Cabal-1.8.0.4...

Re: [Haskell-cafe] Passing Constructors as arguments
Thanks for your help Daniel - I am clarifying my message

Now I need a way to extract properties from the frame. Start by testing
pattern matching
without using parameters. Then I need to find out how to pass a
constructor as a parameter.
Your code works fine.
I'm not sure, what your problem is.
Given type-correctness, data constructors can be passed as arguments to
functions like any other function. Probably that's not your question,
however.
I would like to see an example of passing constructors as arguments. I
am still getting familiar with constructs like:
> getProperty ( a -> b) -> [ContactProperty] -> b
I am not sure how to test the Constructor passed as the argument. Do I
say the following:
> getProperty c ((c v:_) = v
> getProperty c ((_:xs) = getProperty c xs
..
I have tried doing this but GHC gives me parse errors. There is Haskell
syntax that I don't know yet that I need to learn.
As a wild guess, maybe you should use labelled records,
data Contact = Contact
{ firstName :: FirstName
, lastName :: LastName
, ...
}
and you have your selector-functions.
thanks - very useful
And it's possible to define partial contacts as
me = Contact{firstName="Daniel", lastName="Fischer"}
-- just don't ask for my phone-number or anything else which is undefined.
If I'm far off, state your problem more precisely.
> getProperty:: [ContactProperty] -> FirstName
> getProperty ((FN fn):_) = fn
> getProperty (_:xs) = getProperty xs
> getProperty [] = "unknown"
>
> firstName:: Contact -> FirstName
> firstName (Contact cpl) = getProperty cpl
Cheers,
Daniel
