Hi,
I've written a small haskell program to extract a section from a file
between start and end markers. For example, if I have a file such as below
-
a
b
c
<bug>
d
e
f
</bug>
g
h
i
I'd like to extract the contents between <bug> and </bug> (including the
markers).
startTag = "<bug>"endTag = "</bug>"
process = unlines . specialTakeWhile (f endTag) . dropWhile (f
startTag) . lines
where f t x = not (x =~ t)
specialTakeWhile :: (a -> Bool) -> [a] -> [a]
specialTakeWhile ff [] = []
specialTakeWhile ff (x:xs) = if ff x then
x:(specialTakeWhile ff xs) else [x]
It'll be great if I could get some feedback on this.
Regards,
Kashyap

Are there any such matrix algorithms that operate mainly from the start or
end or rows and columns?
Note: If the access pattern starts from the end of a row then one stores
the row in reverse order in a list.

Dear all,
being completely new to Haskell I wanted to explore what DPH is about, so I
tried to install it via
cabal install dph-examples
but the installation process stops once it gets to installing the actual
examples package:
---
Building dph-examples-0.6.1.3...
Preprocessing executable 'dph-spectral-smvm' for dph-examples-0.6.1.3...
[1 of 3] Compiling Vectorised ( examples/spectral/SMVM/dph/Vectorised.hs,
dist/build/dph-spectral-smvm/dph-spectral-smvm-tmp/Vectorised.o )
exprType TYPE ghc-prim:GHC.Types.Double{(w) tc 3u}
exprType TYPE ghc-prim:GHC.Types.Double{(w) tc 3u}
exprType TYPE ghc-prim:GHC.Types.Double{(w) tc 3u}
exprType TYPE ghc-prim:GHC.Types.Double{(w) tc 3u}
exprType TYPE ghc-prim:GHC.Types.Double{(w) tc 3u}
exprType
TYPE (ghc-prim:GHC.Types.Int{(w) tc 3J},
ghc-prim:GHC.Types.Double{(w) tc 3u})
Warning: Couldn't figure out LLVM version!
Make sure you have installed LLVM
ghc: could not execute: opt
cabal: Error: some packages failed to install:
dph-examples-0.6.1.3 failed during the building phase. The exception was:
ExitFailure 1
---
This is the rest of my setup:
Mac OS X 10.7.4
Xcode 4.3.3 + Command Line Tools (from within Xcode)
Haskell Platform 2012.2.0.0 32bit
Why doesn't Haskell find the LLVM compiler? Is there a way to install the
remaining examples without LLVM compilation?
Thanks,
Oliver

Apple doesn't ship the full LLVM suite, but only the small part Apple cares
about; you need to install a full LLVM from somewhere else.

Thanks for your quick answer. So how would I install the full LLVM suite and
make it coexist peacefully with whatever Apple chose to ship?
