Exclude debug JavaScript code during minification

Question

I\'m looking into different ways to minify my JavaScript code including the regular JSMin, Packer, and YUI solutions. I\'m really interested in the new Google Closure Compil

Answer 1

I am with @marcel-korpel. Isn't perfect but works. Replace the debug instructions before minification. The regular expression works in many places. Watch out unenclosed lines.

/console\.[^;]*/gm

Works on:

;;;     console.log("Starting process");
console.log("Starting process");
console.dir("Starting process");;;;;
console.log("Starting "+(1+2)+" processes"); iamok('good');
console.log('Message ' +
    'with new line'
);
console.group("a");
console.groupEnd();
swtich(input){
    case 1 : alert('ok'); break;
    default: console.warn("Fatal error"); break;
}

Don't works:

console.log("instruction without semicolon")
console.log("semicolon in ; string");
