The Glasgow Haskell Compiler (GHC) is a native or machine code compiler for the functional programming language Haskell. [5] It provides a cross-platform software environment for writing and testing Haskell code and supports many extensions, libraries , and optimisations that streamline the process of generating and executing code.
re2c is a free and open-source lexer generator for C, C++, D, Go, Haskell, Java, JavaScript, OCaml, Python, Rust, V and Zig. It compiles declarative regular expression specifications to deterministic finite automata.
The Haskell Platform is a set of software packages, tools, and libraries that create a common platform for using and developing applications in the programming language Haskell. With the Haskell Platform, Haskell follows the same principle as Python: "Batteries included". [3] Since 2022, the Haskell Platform has been deprecated. [4]
Hugs deviates from the Haskell 98 specification [2] in several minor ways. [3] For example, Hugs does not support mutually recursive modules. A list of differences exists. [4] The Hugs prompt is a Haskell read–eval–print loop (REPL). It accepts expressions for evaluation, but not module, type, or function definitions.
It is compatible with the compiler, Glasgow Haskell Compiler (GHC) and the interpreter, Haskell User's Gofer System . It is free and open-source software released under a BSD-style license. In QuickCheck, assertions are written about logical properties that a function should fulfill.
Python uses the following syntax to express list comprehensions over finite lists: S = [ 2 * x for x in range ( 100 ) if x ** 2 > 3 ] A generator expression may be used in Python versions >= 2.4 which gives lazy evaluation over its input, and can be used with generators to iterate over 'infinite' input such as the count generator function which ...
It is dependent on Glasgow Haskell Compiler (GHC), using a modified form of the HsParser (written in Happy) parser for Haskell included in GHC. [6] Its lightweight markup is based on IDoc's. [6] Haddock is contained in the Haskell Platform. It is used by the GHC, Gtk2Hs and HTk projects, [7] as well as xmonad. [citation needed]
