Lexical analysis is the first phase of a compiler. It takes the modified source code from language preprocessors that are written in the form of sentences. The lexical analyzer breaks these syntaxes into a series of tokens, by removing any whitespace or comments in the source code. If the lexical analyzer finds a token invalid, it generates an error.
Lexical Analyzer: Reads Source Program Character-by-Character to Produce Tokens
Lex - A Lexical Analyzer Generator
Explanation: Users write the program in a high-level language because it is easier to use, understand and remember. Explanation: Compiler is a computer program that accepts the code written in a high-level language and converts that code into the assembly language. Explanation: The compiler is that program which translates the whole high-level code into the machine code at once. Explanation: The object file contains the object code, which is an output of an assembler. Explanation: Scanner is a subroutine which is called by the compiler program. The scanner combines the characters and implements them to produce tokens.
Welcome to the NetBeans Platform Schliemann tutorial. Schliemann is a project that allows you to define a programming language and integrate it to NetBeans IDE. This tutorial shows how to add Prolog support to the NetBeans Editor. You are neither required to know anything about NetBeans Platform develop ment nor Prolog to work on this tutorial.
Lex Compiler. Lex and YACC were designed to work together, and are often used together to create compilers. Like Bison, it produces a parser in C. Syntax analysis phase.
