Extended ATG Log Colorizer

===

An attempt at a more detailed colorizer than Kelly Goetsch's classic tool.

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 atg-color

Usage:

The atg-color command reads from the standard output and writes a colorized log

tail -f dynamo.log | atg-color

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

cat dynamo.log | atg-color | less -R

Disclamer - Known Limitations

Functionnal

atg-color 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

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