Attribute grammar in relation to Haskell and functional programming. Jukka Paakki: Attribute grammar paradigms—a high-level methodology in language implementation. ACM Computing Surveys 27:2 (June 1995), 196–255. Ox is an attribute grammar compiling system that augments Lex and Yacc specifications with definitions of synthesized and ...
In computer science, a Van Wijngaarden grammar (also vW-grammar or W-grammar [1]) is a formalism for defining formal languages. The name derives from the formalism invented by Adriaan van Wijngaarden [2] for the purpose of defining the ALGOL 68 programming language. The resulting specification [3] remains its most notable application.
The phrase grammar of most programming languages can be specified using a Type-2 grammar, i.e., they are context-free grammars, [8] though the overall syntax is context-sensitive (due to variable declarations and nested scopes), hence Type-1. However, there are exceptions, and for some languages the phrase grammar is Type-0 (Turing-complete).
L-attributed grammars are a special type of attribute grammars. [1] They allow the attributes to be evaluated in one depth-first left-to-right traversal of the abstract syntax tree. As a result, attribute evaluation in L-attributed grammars can be incorporated conveniently in top-down parsing.
An affix grammar is a two-level grammar formalism used to describe the syntax of languages, mainly computer languages, using an approach based on how natural language is typically described. [ 1 ] The formalism was invented in 1962 by Lambert Meertens while developing a grammar for generating English sentences. [ 2 ]
In computer science, an attributed graph grammar is a class of graph grammar that associates vertices with a set of attributes and rewrites with functions on attributes. In the algebraic approach to graph grammars, they are usually formulated using the double-pushout approach or the single-pushout approach .
Syntax is usually associated with the rules (or grammar) governing the composition of texts in a formal language that constitute the well-formed formulas of a formal system. In computer science, the term syntax refers to the rules governing the composition of well-formed expressions in a programming language. As in mathematical logic, it is ...
The C# language has supported attributes from its very first release. These attributes was used to give run-time information and are not used by a preprocessor. Currently with source generators, you can use attributes to drive generation of additional code at compile-time.
