Compressing javascript
======================

$ cat sample.js |  \
tr -d '\n\t' |  tr -s ' ' \ 
| sed 's:/\*.*\*/::g' \
| sed 's/ \?\([{}();,:]\) \?/\1/g' 

function sign_out(){$("#loading").show();$.get("log_in",{logout:"True"},function(){window.location="";});}

解压缩

用";\n"替换";"

用"{\n"替换"{","\n}"替换"}"

$ cat obfuscated.txt | sed 's/;/;\n/g; s/{/{\n\n/g; s/}/\n\n}/g' 
or
$ cat obfuscated.txt | sed 's/;/;\n/g' | sed 's/{/{\n\n/g' | sed 's/}/\n\n}/g' 

$ cat obfuscated.txt | sed 's/;/;\n/g; s/{/{\n\n/g; s/}/\n\n}/g' 
function sign_out(){

$("#loading").show();
$.get("log_in",{

logout:"True"

},function(){

window.location="";

});
