Colorgs - A Log Colorizer

===

An attempt at a more detailed colorizer than Kelly Goetsch's classic tool, extended for other languages and format than ATG

The goal it to highlight more than just log level : patterns like stacktraces, pipeline logs, and more

Features

color each type of log level
highlight pipeline logs : keywords, chain names, return values
highlight stacktraces : exceptions, class name & line number
highlight component names, some key atg logs (Nucleus Starting), key/value pairs (ex: order=o10000)
filter out elements of the logs, if one has no control over the output pattern

Examples

With solarized terminal colors

Install

npm i -g colorgs

Usage:

The colorgs command reads from the standard output and writes a colorized log

tail -f file.log | colorgs

In order to use it with less, you must pass the -R flag to less, so that less applies the color codes.

cat file.log | colorgs | less -R

note : taking a file as stdin is on the wishlist

Disclamer - Known Limitations

Functionnal

colorgs is based on a parser that must recognize the whole line pattern. Small deviations in the pattern can lead the tool to fail to recognize a line. For now the recognized patterns are limited to ones I've encountered in the projects I worked on. With time the library of patterns will grow. I also intend on making the tool customizable (pattern & color schemes) so that anyone can easily adapt it to their needs.

Performances

colorgs runs on nodejs, it's obviously slower than the original C++ tool. For now it looks fine.
