Cousins Cousins Cousins

I consistently forget the difference between the various kinds of cousins you can have. Fortunately, I recently found a chart that explains it all (and not just cousins) on Wikipedia:

I opened a new IntelliJ issue

I opened an issue for IntelliJ IDEA to highlight TODOs in blue in gsp files like they do for other files tonight. Vote if you're interested.

Greasemonkey and local files

I'm a big fan of the Javadoc Search Frame userscript. Today's apperent outage of the Javadoc page has forced me to use a local copy of the documentation. I did some poking around on the Greasemonkey mailing list and found that if you still want to run this userscript (or any other userscript) on local files, you will need to edit your about:config. An update changed the default greasemonkey.fileIsGreaseable in about:config from true to false for security reasons. If you want to run Greasemonkey on local files, simply change that value to true.

Also, if you're using the shiny new Scriptish, the value to set to true is extensions.scriptish.fileIsGreaseable.

Cheers!

BASH Colors

I was messing with my .dir_colors file (about.com also has a good article on this) and wanted a chart to help me pick out my colors. So I modified the popular script that is floating around on the internet to display every possible combination in a graphical chart.
The way it is read is foreground and effect is on the row titles and the backgrounds are on the column titles. Hopefully someone else will find this useful.

#!/bin/bash
#
#  This file echoes a bunch of color codes to the 
#  terminal to demonstrate what's available.  Each 
#  line is the color code of one forground color,
#  out of 17 (default + 16 escapes), followed by a 
#  test use of that color on all nine background 
#  colors (default + 8 escapes).
# 
#  Attribute codes: 
#   00=none 01=bold 04=underscore 05=blink 07=reverse 08=concealed
#  Text color codes:
#   30=black 31=red 32=green 33=yellow 34=blue 35=magenta 36=cyan 37=white
#  Background color codes:
#   40=black 41=red 42=green 43=yellow 44=blue 45=magenta 46=cyan 47=white
#
#  A quick test can be done by echo -e "\033[<color code><test text>\033[0m"
#   e.g. echo -e "\033[01;32mHello World\033[0m"
#

#echo -e "\n                 40m     41m     42m     43m     44m     45m" \
#        "    46m     47m";
#for FGs in '    m' '   1m' '  30m' '  31m' '  32m' '  33m' '  34m' '  35m' \
#           '  36m' '  37m' ;
echo -e "\n                  40m     41m     42m     43m     44m     45m" \
        "    46m     47m";
for FGs in '     m' '    1m' \
           '   30m' '01;30m' '02;30m' '03;30m' '05;30m' '07;30m' '08;30m' \
           '   31m' '01;31m' '02;31m' '03;31m' '05;31m' '07;31m' '08;31m' \

           '   33m' '01;33m' '02;33m' '03;33m' '05;33m' '07;33m' '08;33m' \
           '   34m' '01;34m' '02;34m' '03;34m' '05;34m' '07;34m' '08;34m' \
           '   35m' '01;35m' '02;35m' '03;35m' '05;35m' '07;35m' '08;35m' \
           '   36m' '01;36m' '02;36m' '03;36m' '05;36m' '07;36m' '08;36m' \
           '   37m' '01;37m' '02;37m' '03;37m' '05;37m' '07;37m' '08;37m';
  do FG=${FGs// /}  
  echo -en " $FGs \033[$FG  $T  "
  for BG in '40m' '41m' '42m' '43m' '44m' '45m' '46m' '47m';
    do echo -en "$EINS \033[$FG\033[$BG  $T  \033[0m";
  done
  echo;
done
echo

As a side note, for those who may be like myself and didn't see any logic to the codes used for colors, ls and most terminals use the ANSI escape codes (ECMA-48), which is where the numbers come from.
