discoball Description

A simple stream filter to highlight patterns discoball is a Python module to filter streams and colorize patterns. It functions somewhat like egrep --color, except that it can highlight multiple patterns (in different colors). Patterns are arbitrary ruby regexes that are matched against the entire line.Usage: discoball < pattern1 pattern2 ... >where options are: --group-colors or -g: Color all matches of the same pattern with the same color --one-color or -o: Highlight all matches with a single color --match-any or -m: Only print lines matching an input pattern --match-all or -a: Only print lines matching all input patterns --help or -h: Print the help messageExamples: Highlight instances of "foo" and "bar" in the text of myfile.txt: cat myfile.txt | discoball foo bar Highlight paths of processes running out of /usr/sbin/: ps -ef | discoball --one-color --match-any '/usr/sbin/.*$' I wrote discoball for use with Steve Losh's todo-list tool, t. I put tags on my tasks annotated with + (inspired by Todo.txt): t Make an appointment with the dentist +health When I list my tasks (using t), I use discoball to highlight the tags with different colors: t | discoball '\+\S+' I can even do some fancier stuff to list particular labels. I have the following function defined in my .bashrc: function tl() { if ; then t | discoball '\+\S+' else t | discoball -a "${@/#/\+}" fi } I can use this as follows: tl # ~> Show the list of tasks, with tags highlighted tl health urgent # ~> Show only tasks tagged with 'health' and 'urgent'Installation:The easiest way to get discoball is by using pip (or easy_install):pip install discoball Requirements: · Python
