In computer science, syntactic sugar is syntax within a programming language that is designed to make things easier to read or to express. It makes the language "sweeter" for human use: things can be expressed more clearly, more concisely, or in an alternative style that some may prefer.
So the "I" is merely syntactic sugar. Since I is optional, the system is also referred as SK calculus or SK combinator calculus. It is possible to define a complete system using only one (improper) combinator. An example is Chris Barker's iota combinator, which can be expressed in terms of S and K as follows: ιx = xSK
It is a declarative and visual programming language based on influence diagrams. FlexPro is a program for data analysis and presentation of measurement data. It provides a rich Excel-like user interface and its built-in vector programming language FPScript has a syntax similar to MATLAB. FreeMat, an open-source MATLAB-like environment with a ...
Authors often introduce syntactic sugar, such as let, [k] to permit writing the above in the more intuitive order let f = N in M. By chaining such definitions, one can write a lambda calculus "program" as zero or more function definitions, followed by one lambda-term using those functions that constitutes the main body of the program.
Landin is responsible for inventing the stack, environment, control, dump SECD machine, the first abstract machine for a functional programming language, [12] and the ISWIM programming language, defining the Landin off-side rule and for coining the term syntactic sugar.
This is only syntactic sugar that disguises a monadic pipeline as a code block; the compiler will then quietly translate these expressions into underlying functional code. Translating the add function from the Maybe into Haskell can show this feature in action.
In a similar fashion, the properties of components in a Power Fx program are connected by formulas (whose syntax is very reminiscent of Excel) and their values are automatically updated if changes occur. For instance, a simple formula may connect a component's color property to the value of a slider component; if the user moves the slider, the ...
This article describes the syntax and semantics of the purely declarative subset of these languages. Confusingly, the name "logic programming" also refers to a specific programming language that roughly corresponds to the declarative subset of Prolog. Unfortunately, the term must be used in both senses in this article.
