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.
Bluespec SystemVerilog (BSV) is a language extension of Haskell, for designing electronics. It is an example of a domain-specific language embedded into Haskell. Further, Bluespec, Inc.'s tools are implemented in Haskell. Cryptol, a language and toolchain for developing and verifying cryptography algorithms, is implemented in Haskell.
In languages which support first-class functions and currying, map may be partially applied to lift a function that works on only one value to an element-wise equivalent that works on an entire container; for example, map square is a Haskell function which squares each element of a list.
In computer science, the syntax of a computer language is the rules that define the combinations of symbols that are considered to be correctly structured statements or expressions in that language. This applies both to programming languages , where the document represents source code , and to markup languages , where the document represents data.
As another example, the list of all Fibonacci numbers can be written in the programming language Haskell as: [13] fibs = 0 : 1 : zipWith ( + ) fibs ( tail fibs ) In Haskell syntax, " : " prepends an element to a list, tail returns a list without its first element, and zipWith uses a specified function (in this case addition) to combine ...
This was later adopted by Miranda, and Haskell adopted a similar (but rather more complex) version of Miranda's off-side rule, which is called "layout". Other languages to adopt whitespace character-sensitive syntax include Python and F#. The use of layout in Haskell is optional. For example, the function product above can also be written:
A concatenative programming language is a point-free computer programming language in which all expressions denote functions, and the juxtaposition of expressions denotes function composition. [4] Concatenative programming replaces function application , which is common in other programming styles, with function composition as the default way ...
