| | Lex programming tool - Wikipedia, the free encyclopedia |
 | | Lex is a program that generates lexical analyzers ("scanners"). | | | When lex sees a pattern in its input matching a given rule, it executes the associated C code. | | | The following is an example input file for the flex version of lex. |

| | CSCI524 Programming Language Principles |
| | Languages are classified as low level if they are close to machine code and high level if each language statement corresponds to many machine code instructions (though this could also apply to a low level language with extensive use of macros, in which case it would be debatable whether it still counted as low level). | | | A programming environment is the collection of tools used in the development of software. | | | The semantics of a programming language is a function from programs to answers. |

| | The Lex programming language and its compiler is designed to generate code for fast lexical analysers based on a formal description of the lexical syntax. | | | Lexical analysis is the process of taking an input string of characters (such as the source code of a computer program) and producing a sequence of symbols called "lexical tokens", or just "tokenss", which may be handled more easily by a parser. | | | Each regular expression is associated with a phrase in a programming language which will evaluate the lexemes that match the regular expression. |

| | Lex - A Lexical Analyzer Generator |
| | Lex is not a complete language, but rather a generator representing a new language feature which can be added to different programming languages, called ``host languages.'' Just as general purpose languages can produce code to run on different computer hardware, Lex can write code in different host languages. | | | Lex is a program generator designed for lexical processing of character input streams. | | | The table is translated to a program which reads an input stream, copying it to an output stream and partitioning the input into strings which match the given expressions. |

| | RIGAL PROGRAMMING SYSTEM LANGUAGE DESCRIPTION |
| | Programming language RIGAL is intended to be a tool for parsing (context checking, diagnosing and neutralization of errors included), for code optimization, code generation, static analysis of programs, as well as for the programming of preprocessors and convertors. | | | Pattern matching is a convenient tool for programming of parsing, optimization and code generation. | | | Dependence of control structures in the program from data structures used for program's work is one of the basic principles in programming. |

| | The language was built upon the object-oriented model of Simula and designed to work directly with the newly developed concept of the graphic user interface (GUI), To this day, Smalltalk is considered one of the "purest" object-oriented programming languages. | | | The Smalltalk programming language was developed at the Xerox labs at Palo Alto in the mid 1970s. | | | The language is unique in a number of ways - which include the features of the language and the programming "culture" involved. |

| | GOLD Parsing System - A Free, Multi-Programming Language, Parser |
| | Rather than taking on the tedious task of writing the program using the actual machine code used by the computer processor, the logic and behavior of the program are expressed using human-like and English-like terms. | | | When a software engineer writes a program, it is often in one of the many modern programming languages available. | | | Since the parse tables are programming language independent, the parser engine can be, and has been, easily implemented in different programming languages. |

| | Lex is a lexical analyzer generator for the UNIX operating system, targeted to the C programming language. | | | Lex takes a specially-formatted specification file containing the details of a lexical analyzer. | | | Writing lexical analyzers by hand can be a tedious process, so software tools have been developed to ease this task. |

| | This eliminates the need to include programming language statements in the grammar definition--resulting in grammars that are programming language independent, less cluttered, and more reusable across multiple applications having different uses for the same data. | | | Yacc operates in coordination with Lex, which is a lexical analyzer (or tokenizer) that scans the input to produce a sequence of tokens. | | | In Yacc, semantic actions consist of C language statements that are entered directly into the grammar definition. |

| | perl.com: Perl, the first postmodern computer language |
| | One of the characteristics of a postmodern computer language is that it puts the focus not so much onto the problem to be solved, but rather onto the person trying to solve the problem. | | | The very fact that it's possible to write messy programs in Perl is also what makes it possible to write programs that are cleaner in Perl than they could ever be in a language that attempts to enforce cleanliness. | | | So, to drag the subject back to computers, one of the characteristics of a postmodern computer language is that it puts the focus not so much onto the problem to be solved, but rather onto the person trying to solve the problem. |
