How do they color code source code in an IDE. What is the basic indea behind it? What are they tokens they look for?
The most common approach that I know of is the use of single- or multi-line regexes, depending on language syntax.
For IDEs with syntax files, the IDE compiles the file into a regex on first load of relevant file.
