Add colors to plain text lines matching either a Python string or regular expression

pip install


There is at least one existing tool to perform automatic syntax highlighting of code and output ANSI escape sequences. Unfortunately, to the best of the author's knowledge, there is no existing tool for highlighting lines of log files that contain a particular pattern. Vim's match and 2match are close, but a little kludgy to use.

The purpose of this tool is to colorize lines matching a particular pattern, to make it easier to highlight relevant lines in a log file, when poring over such files with your coworker or manager.
