fst -opengl

fst :: (a, b) -> a
base Prelude, base Data.Tuple
Extract the first component of a pair.
package fst
Fst is an application for construction and running of finite state transducers, as based on the concepts of transducers and regular relations developed by Xerox.  The syntax of Xerox's fst program has functioned as an inspiration for the syntax of fstStudio. The application was written purely in Haskell, and is intended to be a tool for the Haskell programmer, especially for ones that develop language applications. This package provides an interactive shell for parsing transducers specified in a specialized FST language. See FST.FSTStudio. This package also provides a programmer's interface for building and applying transducers. See FST.TransducerInterface. Version
deRefStablePtr :: StablePtr a -> IO a
base Foreign.StablePtr
Obtain the Haskell value referenced by a stable pointer, i.e., the same value that was passed to the corresponding call to makeStablePtr. If the argument to deRefStablePtr has already been freed using freeStablePtr, the behaviour of deRefStablePtr is undefined.
