Syntax (programming languages)

In computer science , the syntax of a computer language is the set of rules that defines 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. The syntax of a language defines its surface form. Documents that are syntactically invalid are said to have a syntax error. When designing the syntax of a language, a designer might start by writing down examples of both legal and illegal strings , before trying to figure out the general rules from these examples. Syntax therefore refers to the form of the code, and is contrasted with semantics — the meaning.

The security of blockchain smart contracts is one of the most emerging issues of the greatest interest for researchers. This article presents an intermediate specification language for the formal verification of Ethereum-based smart contract in Coq, denoted as Lolisa. The formal syntax and semantics of Lolisa contain a large subset of the Solidity programming language developed for the Ethereum blockchain platform. To enhance type safety, the formal syntax of Lolisa adopts a stronger static type system than Solidity. In addition, Lolisa includes a large subset of Solidity syntax components as well as general-purpose programming language features.

Он являл собой печальное зрелище. - Это сделаю я, - сказал он, встал и, спотыкаясь, начал выбираться из-за стола. Сьюзан, чуть подтолкнув, усадила его на место. - Нет! - рявкнула.  - Пойду я! - Ее тон говорил о том, что возражений она не потерпит.

На это уходило много времени, но математически гарантировало успех.

С пистолетом в руке он рвался вперед, к тупику. Но Беккера там не оказалось, и он тихо застонал от злости. Беккер, спотыкаясь и кидаясь то вправо, то влево, продирался сквозь толпу. Надо идти за ними, думал .

 Кто вы такой? - потребовала. Беккер перешел на испанский с ярко выраженным андалузским акцентом: - Guardia Civil. Росио засмеялась. - Не может быть! - сказала она по-испански. У Беккера застрял комок в горле.

Уже теряя сознание, она рванулась к свету, который пробивался из приоткрытой двери гостиничного номера, и успела увидеть руку, сжимающую пистолет с глушителем. Яркая вспышка - и все поглотила черная бездна. ГЛАВА 40 Стоя у двери Третьего узла, Чатрукьян с безумным видом отчаянно пытался убедить Хейла в том, что с ТРАНСТЕКСТОМ стряслась беда. Сьюзан пробежала мимо них с одной только мыслью - как можно скорее предупредить Стратмора. Сотрудник лаборатории систем безопасности схватил ее за руку.
