How to match every file but one in grunt concat?

Question

I'm using grunt to concatenate and minimize my js files, I use the following config for the concat part:

concat: {
  dist: {
    src: ['<banner:meta.banner>', 'js/*.js'],
    dest: 'js/script.js'
  }
}

It matches every file in my js folder but I need to ignore modernizr.js, is there a way to do this? I assume I'd need some pattern matching voodoo to do it but I'm not sure how.

Thanks in advance.

Note that 'js/*.js' is not a regex, it is a path selector (or whatever they are called). A regex would have been js\/.*\.js (.* instead of *, and escaping the dot, at least). I'd look into other ways of excluding files, it may have additional configurations. – Waxbill

You're right, it uses minimatch for file selection which converts expressions into JavaScript RegExp objects so it's not 100% regex – Benedikt

Based on documentation I would try:

js/!(modernizr).js
(js/)!(modernizr).js
{js/}!(modernizr).js
js/!({modernizr}).js
(js/)!({modernizr}).js
{js/}!({modernizr}).js
js/!{modernizr}.js
(js/)!{modernizr}.js
{js/}!{modernizr}.js

If none of them is going to work, then probably you are of out luck...

Thanks the first one worked fine, I was trying js/!modernizr.js before no wonder why it didn't work... – Benedikt

@javiervd - In js/!modernizr.js you used negation just for letter m, that's why it didn't work... – Debutant
