In computer programming and software design, code refactoring is the process of restructuring existing source code —changing the factoring —without changing its external behavior. Refactoring is intended to improve the design, structure, and/or implementation of the software (its non-functional attributes), while preserving its functionality.
Equations and rewrite rules can also be conditional rules, which means they have to fulfill some criteria to be applied to the term (other than just matching the left hand side of the rewrite rule). The rules are applied at "random" by the Maude system, meaning that you can not be sure that one rule is applied before another rule and so on.
A critical pair arises in a term rewriting system when two rewrite rules overlap to yield two different terms. In more detail, ( t 1 , t 2 ) is a critical pair if there is a term t for which two different applications of a rewrite rule (either the same rule applied differently, or two different rules) yield the terms t 1 and t 2 .
In computer programming, an assignment statement sets and/or re-sets the value stored in the storage location (s) denoted by a variable name; in other words, it copies a value into the variable. In most imperative programming languages, the assignment statement (or expression) is a fundamental construct. Today, the most commonly used notation ...
A production or production rule in computer science is a rewrite rule specifying a symbol substitution that can be recursively performed to generate new symbol sequences. A finite set of productions is the main component in the specification of a formal grammar (specifically a generative grammar ). The other components are a finite set of ...
Rewrite (programming) A rewrite in computer programming is the act or result of re-implementing a large portion of existing functionality without re-use of its source code. When the rewrite uses no existing code at all, it is common to speak of a rewrite from scratch .
C is a fairly small language, with only a handful of statements, and without too many features that generate extensive target code – it is comprehensible. C has direct control over memory allocation and deallocation, which gives reasonable efficiency and predictable timing to memory-handling operations, without any concerns for sporadic stop ...
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.
