What is ansi-regex?
The ansi-regex npm package is used to create regular expressions to match ANSI escape codes, which are used to format output in terminal with colors, background colors, styles like bold or underline, and other text effects.
What are ansi-regex's main functionalities?
Matching ANSI escape codes
This code sample demonstrates how to use ansi-regex to match ANSI escape codes in a string. The string contains the ANSI escape codes for underlining text, followed by the word 'cake', and then the reset code to stop the underlining. The ansiRegex function is called to generate a regular expression that matches these codes.
"\u001B[4mcake\u001B[0m".match(ansiRegex());
Other packages similar to ansi-regex
strip-ansi
strip-ansi is a package that removes ANSI escape codes from strings. It is similar to ansi-regex in that it deals with ANSI codes, but instead of matching them, it strips them from the text, which can be useful for cleaning up terminal output for logging or processing.
chalk
chalk is a popular package for styling terminal output with ANSI escape codes. It provides a more user-friendly API for applying styles compared to manually writing escape codes. While ansi-regex is used for detecting ANSI codes, chalk is used for generating them.
