  • Ever compress a file for the web by replacing all newline characters with nothing so it makes one nice big blob? It is a great idea, however what about when you want to edit that file? ...Serious pain in the butt. I ran into this today in that my only copy of a CSS file was "compressed" with no newlines. I whipped this up and it converted back into nice human readable CSS :-) It could be nicer, but it does the job.

    cat somefile.css | awk '{gsub(/{|}|;/,"&\n"); print}' >> uncompressed.css

  • This searches through all CSS files in the current directory and sub-directories, matches the content between "url(...)", and prints a list of all the URLs. If you prefer to see the file the URL came from, remove the -h and --nogroup params. Show Sample Output

    ack -o -h --nogroup --css 'url\((.*)\)' --output "\$1"

  • This will extract the differing CSS entries of two files. I've left the initial character (plus or space) in output to show the real differing line, remove the initial character to get a working CSS file. The output CSS file is usable by either adding it in a below the to original.css, or by only using the output but adding @import url("original.css"); in the beginning. This is very useful for converting Wordpress theme copies into real Wordpress child themes. Could exclude common lines within entries too, I guess, but that might not be worth the complexity. Show Sample Output

    diff -U99999 original.css modified.css | awk '/^-/{next} {f=f"\n"$0} /^\+.*[^ ]/{yes=1} /}/ {if(yes){print f} f="";yes=0}'

  • With code, the only way to have spaces parsed correctly in any kind of portable way is to use ... but then long lines will not wrap. That's kinda important for low-res screens or smaller windows. Ideally, code blocks would be wrapped to the screen width, with line numbers and syntax hilighted, so that if someone does "view source", they'd see the unadulterated code for cutting and pasting. Then have all formatting done by CSS and javascript, such that: - if someone copies the text as displayed in any browser, they'll get properly formatted code in their clipboard, without wrapping - it fails gracefully so that it looks at least reasonable in all browsers, even those that don't know CSS/JS and can't do colours (eg lynx, screen readers) If anyone knows a way, that would make me happy. Until then, I am stuck with the above as the best I can do. For example, in LiveJournal, something like this: <div width="100%" style="(the code above)"><pre>Code goes here</pre> ... will look considerably better and more readable than the default <blockquote><pre></pre></blockquote>. It's not perfect, of course. If you have enough control to create your own css file, you should definitely do that instead.

    overflow:auto;padding:5px;border-style:double;font-weight:bold;color:#00ff00;background-color:0;"><pre style="white-space:pre-wrap;white-space:-moz-pre-wrap !important;white-space:-pre-wrap;white-space:-o-pre-wrap;word-wrap:break-word;_white-space:pre;

  • Count the number of unique colors there are in a websites css folder (136 is way too many imho time to get people stick to a color scheme) Show Sample Output

Adding Color Escape Codes to global CC array for use by echo -e
I was looking for the fastest way to create a bunch of ansi escapes for use in echo -e commands throughout a lot of my shell scripts. This is what I came up with, and I actually stick that loop command in a function and then just call that at the beginning of my scripts to not clutter the environment with these escape codes, which can wreck havok on my terminal when I'm dumping the environment. More of a cool way to store escape ansi codes in an array. You can echo them like: $ echo -e "${CC[15]}This text is black on bright green background." I usually just use with a function: $ # setup_colors - Adds colors to array CC for global use $ # 30 - Black, 31 - Red, 32 - Green, 33 - Yellow, 34 - Blue, 35 - Magenta, 36 - Blue/Green, 37 - White, 30/42 - Black on Green '30\;42' $ function setup_colors(){ declare -ax CC; for i in `seq 0 7`;do ii=$(($i+7));CC[$i]="\033[1;3${i}m";CC[$ii]="\033[0;3${i}m";done;CC[15]="\033[30;42m"; export R='\033[0;00m';export X="\033[1;37m"; }; $ export -f setup_colors CC[15] has a background of bright green which is why it is separate. R resets everything, and X is my default font of bright white. $ CC[15]="\033[30;42m"; R=$'\033[0;00m'; X=$'\033[1;37m' Those are just my favorite colors that I often use in my scripts. You can test which colors by running $ for i in $(seq 0 $((${#CC[@]} - 1))); do echo -e "${CC[$i]}[$i]\n$R"; done See: for more usage.
