= grepblush A simple python script through which you can pipe things like log files and get colorized lines based on regular expression matching. There are more advanced options out there: * grc http://korpus.juls.savba.sk/~garabik/software/grc.html * pygmentize http://pygments.org/docs/cmdline/ * and others I'm sure... which handle regexps in parts of lines etc. I just wanted something that did dead simple full line matching with colors. = Usage Assuming grepblush.py is available in your path, you'll probably want to do something like: cmd_producing_log | grepblush.py matchfile = Matchfile syntax The matchfile syntax is: regex=color Where regex is a python regular expression (which has to match the line using *match*, not find). The regular expression may contain the char '=', as the parser looks for the last = in the line when parsing. The color designation should either be a bash color code (e.g. 0;30 for black), or one of the special built in codes: red, yellow, green, blue, purple, or light_gray. Regexs are attempted in the order they appear in the matchfile, and the first match is used to determine the color. This means you can use a default at the bottom of the file, for example: =light_gray To make any non-matching lines even easier to ignore. See matchfile.sample for a sample file suitable for log4j and imitators. = Bugs Please report them at github if you find them!
