S/sl, or Syntax/Semantics Language, is a high-level specification language used for defining the syntax and semantics of programming languages. It allows developers to describe language constructs and their associated behaviors in a formalized manner, often used in compiler construction and language design.

An S/sl expert must have strong skills in formal language theory, compiler design, and syntax analysis. Proficiency in writing and understanding formal specifications, as well as experience with parsing algorithms and semantic analysis, are also essential.

How to hire a S/sl expert

S/sl was created in the late 1970s as a tool for defining the syntax and semantics of programming languages. It was developed to assist in compiler construction by providing a formal method to specify language constructs and their behaviors.

About S/sl

Strengths of S/sl included its formal approach to defining language syntax and semantics, which made it useful for compiler construction. Weaknesses involved its complexity and the steep learning curve for new users. Competitors included other specification languages like BNF (Backus-Naur Form) and EBNF (Extended Backus-Naur Form).
