Rewrite rules have names, e.g. simplify_conditional_assignment. Each rule has a "match this" and "replace by that" pattern pair separated by -> , in our example, on separate lines for readability. The patterns must correspond to language syntax categories; in this case, both patterns must be of syntax category statement also separated in ...
Self-modifying code can involve overwriting existing instructions or generating new code at run time and transferring control to that code. Self-modification can be used as an alternative to the method of "flag setting" and conditional program branching, used primarily to reduce the number of times a condition needs to be tested.
Formally, a graph rewriting system usually consists of a set of graph rewrite rules of the form , with being called pattern graph (or left-hand side) and being called replacement graph (or right-hand side of the rule). A graph rewrite rule is applied to the host graph by searching for an occurrence of the pattern graph (pattern matching, thus ...
A string rewriting system or semi-Thue system is a tuple (,) where . is an alphabet, usually assumed finite. [5] The elements of the set (* is the Kleene star here) are finite (possibly empty) strings on , sometimes called words in formal languages; we will simply call them strings here.
The Rule Interchange Format (RIF) is a W3C Recommendation.RIF is part of the infrastructure for the semantic web, along with (principally) SPARQL, RDF and OWL.Although originally envisioned by many as a "rules layer" for the semantic web, in reality the design of RIF is based on the observation that there are many "rules languages" in existence, and what is needed is to exchange rules between ...
In web applications, a rewrite engine is a software component that performs rewriting on URLs (Uniform Resource Locators), modifying their appearance. This modification is called URL rewriting . It is a way of implementing URL mapping or routing within a web application .
Given a set E of equations between terms, the following inference rules can be used to transform it into an equivalent convergent term rewrite system (if possible): [4] [5] They are based on a user-given reduction ordering (>) on the set of all terms; it is lifted to a well-founded ordering ( ) on the set of rewrite rules by defining (s → t) (l → r) if
