fixbug for get part of filename when filename contains two '.'

[yss]

when use Building the files object dynamically
like this:

{
    expand: true,
    src: [PATH_SRC + APP_NAME + '/*.js', PATH_SRC + APP_NAME + '/**/*.js'],
    dest: PATH_DEST,
    ext: '.js',
    rename: function(dest, src) { console.log(src);
        var version = getVersion(src, PATH_TMP + APP_NAME + '.json', grunt);
        return version && (dest + version);
    }
}

If there has a js file like zepto.min.js, and the output is zepto.js.

My project is broken by this problem.
Hope you can fix it quickly.
And I will report a new version for my own project.

Thanks but closing as this is a duplicate of #750, #625, #718, #730.

There's two ways ext could work; it could consider everything after the first dot the extension, or everything after the last dot the extension—it can't be smart enough to "guess" automatically. We chose the former because the use-case is more common (we encounter .min.js files all the time). That being said, you can use the rename option to specify a function that will use whatever custom naming logic you need.

FWIW, I believe support for this way was added in globule which will eventually get upstreamed into grunt.

@shama that paragraph should probably be in the FAQ in the wiki as I've seen it asked countless of times.

This has been resolved with the extDot option. See:
