Syntax highlighting
Syntax highlighting is a feature of some text editors that displays text—especially source code—in different colors and fonts according to the category of terms. This feature eases writing in a structured language such as a programming language or a markup language as both structures and syntax errors are visually distinct.
Users can specify the language of the text, such as C, LaTeX, HTML, or the text editor can automatically recognize it based on the contents or name of the file.
Text editors that have syntax highlighting include the following:
Example
Below is a snippet of C++ code which the editor has automatically highlighted based on the syntax:
// Allocate all the windows
for( int i=0; i < max; i++ )
{
pWins[i] = new Window();
}
In this example, the editor has recognized the keywords for, int and new. It recognized the variable names i, pWins and max and highlighted them accordingly. The comment before the code is also highlighted in a specific manner to distinguish it from working code. When looking at pages and pages of code, syntax hightlighting greatly improves the readability and context of the text. The reader can automatically ignore large sections of comments or code, depending on what one desires.
