extract_files 0.0.1

# extract_files Extract files from files or stdin for a given extension. ## Yes, but i can do that with sed. I know. Before this I use this snippet: for css_file in `find css -name "*.css" ` ; do sed -n 's/^.*url *( *"*\'"'"'*\([^"]*\)\'"'"'*"* *).*$/'`dirname $css_file`'\/\1/p' $css_file ; done | ruby -n -e "puts File.expand_path(\$_)[File.expand_path('.').size+1..-1]" Probably could be improve. ## Usage Given a css file with absolute and relative images $ cat style.css body { background: url(../images/bg.jpg), url ( ../images/bg2.jpg ); background: url("../images/bg3.jpg"); background: url('/images/bg4.jpg); background: url('images/bg5.jpg'); } Extract the images only ``-e jpg -e png -e gif`` $ cat style.css | extract_files -e jpg ../images/bg.jpg ../images/bg2.jpg ../images/bg3.jpg /images/bg4.jpg images/bg5.jpg Now, relative to the css directory ``-b css`` $ cat style.css | extract_files -e jpg -b css css/../images/bg.jpg css/../images/bg2.jpg css/../images/bg3.jpg css/images/bg4.jpg css/images/bg5.jpg And do the path expansion ``-p``. $ cat style.css | extract_files -e jpg -b css -p images/bg.jpg images/bg2.jpg images/bg3.jpg css/images/bg4.jpg css/images/bg5.jpg Or show the full path ``-f``. $ cat style.css | extract_files -e jpg -b css -p -f /Users/guillermo/Documents/extract_files/images/bg.jpg /Users/guillermo/Documents/extract_files/images/bg2.jpg /Users/guillermo/Documents/extract_files/images/bg3.jpg /Users/guillermo/Documents/extract_files/css/images/bg4.jpg /Users/guillermo/Documents/extract_files/css/images/bg5.jpg You can pass the file/files directly: $ extract_files * -e png image1.png /images/img1.png ## Install There are two ways of installing this small libbrary: ### Rubygems $ gem install extract_files You will have the code as a library and the binary ### Script only curl -O https://raw.github.com/guillermo/extract_files/master/bin/extract_files chmod +x extract_files ## Development The script is generated automatically with rake, so if you fork, ensure that you edit the correct files. ## License <pre> ____ __ __ | __ ) ___ ___ _ _\ \ / /_ _ _ __ ___ | _ \ / _ \/ _ \ '__\ \ /\ / / _` | '__/ _ \ | |_) | __/ __/ | \ V V / (_| | | | __/ |____/ \___|\___|_| \_/\_/ \__,_|_| \___| _ _ | | (_) ___ ___ _ __ ___ ___ | | | |/ __/ _ \ '_ \/ __|/ _ \ | |___| | (_| __/ | | \__ \ __/ |_____|_|\___\___|_| |_|___/\___| ---------------------------------------------------------------------------- "THE BEER-WARE LICENSE" (Revision 42): guillermo@cientifico.net wrote this file.
