szintaxiskiemelés

Szintaxiskiemelés, often referred to as syntax highlighting, is a feature in text editors and integrated development environments (IDEs) that displays source code in different colors and fonts according to the category of terms. This makes code easier to read and understand by visually distinguishing keywords, variables, strings, comments, and other elements of a programming language.

The primary purpose of syntax highlighting is to improve code readability and to help programmers quickly identify errors. By categorizing different parts of the code, developers can spot syntax mistakes, such as missing punctuation or incorrect keyword usage, more readily. It also aids in comprehending complex code structures and understanding the flow of a program. Different languages have different syntaxes, and syntax highlighting engines are designed to recognize these specific patterns.

The implementation of syntax highlighting typically involves a lexer, which breaks down the source code into a stream of tokens, and a renderer, which applies specific styles to each token based on its type. This process is performed in real-time as the user types or when a file is opened. The colors and styles used can often be customized by the user to suit their preferences. Many modern text editors and IDEs support a wide range of programming languages out of the box, with plugins or extensions available for less common ones. This feature has become a standard expectation for anyone working with code.
