ap -bytestring -fgl
In many situations, the liftM operations can be replaced by uses of ap, which promotes function application.
> return f `ap` x1 `ap` ... `ap` xn
is equivalent to
> liftMn f x1 x2 ... xn
The computation appendFile file str function appends the string str, to the file file.
Note that writeFile and appendFile write a literal string to a file. To write a value of any printable type, as with print, use the show function to convert the value to a string first.
> main = appendFile "squares" (show [(x,x*x) | x <- [0,0.1..2]])
approxRational, applied to two real fractional numbers x and epsilon, returns the simplest rational number within epsilon of x. A rational number y is said to be simpler than another y' if
* abs (numerator y) <= abs (numerator y'), and
* denominator y <= denominator y'.
Any real interval contains a unique simplest rational; in particular, note that 0/1 is the simplest rational of all.
A gtk2hs server and clan browser for the open source game Tremulous http://tremulous.net. Both Tremulous 1.1 and GPP are supported. Features filtering, player search, a list of online clan members, a clan list and basic perferences.
A simple applicative parser in Parsec style
O(n) Appends one Text to the other by copying both of them into a new Text. Subject to fusion.
O(n\c)/ Appends one Text to another. Subject to fusion.
Write a string the end of a file.
Some instances for applicative functors and type-level composition. Forkable on github.
Any applicative functor can be given numeric instances in a boilerplate way. The applicative-numbers package provides an include file that makes it a snap to define these instances. See Data.Numeric.Function for an example.

Instances of Num classes for applicative functors. To be #include'd after defining APPLICATIVE as the applicative functor name and CONSTRAINTS as a list of constraints, which must carry its own trailing comma if non-empty. The APPLICATIVE symbol gets #undef'd at the end of the include file, so that multiple includes are convenient.
@ #define INSTANCE_Ord #define INSTANCE_Enum
#define APPLICATIVE Vec2 #include "ApplicativeNumeric-inc.hs"
#define APPLICATIVE Vec3 #include "ApplicativeNumeric-inc.hs"
#define APPLICATIVE Vec4 #include "ApplicativeNumeric-inc.hs" @
You'll also have to import pure and liftA2 from Control.Applicative and specify the FlexibleContexts language extension (due to an implementation hack).
Some instances are generated only if a corresponding CPP symbol is defined: INSTANCE_Eq, INSTANCE_Ord, INSTANCE_Show, INSTANCE_Enum
Quasiquoters taken from Matt Morrow's haskell-src-meta to implement Conor McBride's idiom brackets, and a do-notation that only requires Applicative (and is correspondingly less powerful).
applicative-quoters currently has no maintainer: if it is broken and you want it to be fixed, then fix it!
Utility to perform approximate randomization tests.
