I got a snippet of the code (called primes) from online. Lastly, if you try to determine whether a number (in your case fst t, again in partC and partD) is prime or a Fibonacci number by checking whether it's an element tr command has no effect when used in $() and saved in a variable What shape is a Calippo? Bam! more info here
In particular we have found that GHC's default is equivalent to -XHaskell2010 -XNondecreasingIndentation. Why not to cut into the meat when scoring duck breasts? This is what gave you the indentation error. In particular: Anytime there is a parse error caused by a malformed if, case, lambda, or (non-monadic) let, ghc will now remind the programmer of the correct syntax.
It takes up roughly half the space that the C++ code does, yet they both output hello world when the correct number is entered. Both error messages let the programmer know where the mistake happened, but the g++ message is far more helpful. Loading package base ...

There is no option for the third mode of operation, namely 'make it behave in a GHC-specific way', so it makes some sense that ghci sets it as the detault. FP Complete member snoyberg commented May 27, 2014 I'm fine with moving to Haskell2010 as the new standard for all code in the IDE. Not talking about ghci here. http://stackoverflow.com/questions/11141272/possibly-incorrect-indentation-in-haskell-case-statement Passing different value (link value) from VF page to VF component and display it on screen How do creatures affected by Compelled Duel or Bear Totemic Attunement know who to attack?

It tells me that there are not enough arguments in my function call.
I've read the docs of 7.4 and 7.8 and it seems that indeed the default GHC mode differs from Haskell2010 standard only by NondecreasingIndentation. http://back2cloud.com/parse-error/parse-error-parse-error-unexpected-t-string-expecting-t-function.php Cool. permalinkembedsavegive gold[–]creepingdeathv2[S] 2 points3 points4 points 1 year ago(0 children)the "equal to"!

That sounds good to me.

FP Complete member snoyberg commented May 15, 2014 Can you make the default language a configuration value? Browse other questions tagged haskell or ask your own question. I agree setting both to Haskell2010 would make it consistent, future-proof and in agreement to what most people write in their .cabal files.
