Static Semantics CFGs cannot describe all of the syntax of programming languages--context-specific parts are left out Static semantics refers to type checking and resolving declarations; has nothing to do with "meaning" in the sense of run-time behavior Often described using an attribute grammar(AG) (Knuth, 1968)

Static and Dynamic Semantics of NoSQL Languages Véronique Benzaken 1Giuseppe Castagna2 Kim Nguyên˜ Jérôme Siméon3 1LRI, Université Paris-Sud, Orsay, France, 2CNRS, PPS, Université Paris Diderot, Sorbonne Paris Cité, Paris, France 3IBM Watson Research, Hawthorne, NY, USA Abstract We present a calculus for processing semistructured data that spans static semantics in a sentence - Use "static semantics" in a sentence 1. These properties do not exist in a vacuum; they are linked to the semantics of the programming language they describe, and there is a large space of varied languages that can fit these criteria, since the notion of " well typed " program is part of the static semantics of the programming language and the notion of Static Semantics High-Level Petri Nets—Extensions, Analysis, and Applications.

Tasks of the Semantic Analyzer •Find the declaration that defines each identifier instance •Determine the static types of expressions •Perform re-organizations of the AST that were inconvenient in parser, or required semantic information •Detect errors and fix to allow further processing Aspects of Language: Syntax, Static Semantics & Semantics Syntax: Let’s take an example to understand this. for example: “Mouse Cat Dog” is not in a correct syntax as far as English language is concerned. Static objects are constructs (identifiers, statements, expressions etc.) in the text of the program, and have no meaningful existence beyond compile-time. Dynamic objects are (instances of) values, locations and the like, which live and move and have their being inside the computer at run-time. Static and Dynamic Semantics. Syntax concerns the form of a valid program, while semantics concerns its meaning; Static semantic rules are enforced by a compiler at compile time; Implemented in semantic analysis phase of the compiler In C++ specifically, what are the semantic differences between for example: static const int x = 0 ; and .

On to Static Semantics •Lexical analysis –Produces tokens –Detects & eliminates illegal tokens •Parsing –Produces trees –Detects & eliminates ill-formed parse trees •Static semantic analysis –Produces “decorated tree” with additional information attached –Detects & eliminates remaining static errors To understand the relationship between syntax, static semantics, and semantics, making a parallel to English language might help.

In computer science, the term semantics refers to the meaning of language constructs, as opposed to their form . According to Euzenat, semantics "provides the rules for interpreting the syntax which do not provide the meaning directly but constrains the possible interpretations of what is declared." Programming languages Static Semantics Most programming languages exhibit a phase distinction between the static and dynamic phases of processing. The static phase consists of parsing and type checking to ensure that the program is well-formed; the dynamic phase consists of execution of well-formed programs.

The Formal Semantics spec defines static typing pessimistically. That is, the rules derive the types of all expressions in a manner that guarantees that no type errors can occur at query evaluation time.

The equations are solved iteratively over some abstract domain. If 2014-10-30 · Static Semantics "static" here means "at compile time", as opposed to "dynamic", which means "at run time" in the context of an interpreted language, substitute "at definition time" and "at evaluation time" "semantics" here has little to do with meaning, but lots to do with semantic information management 3 Static Semantics The static semantics ﬁlters the set of syntactically correct programs to exclude those programs that are not well-typedaccording to the rules in Figure 1.

Then we verify that the abstract syntax satisﬁes the requirements of the static semantics.
