Bracket formatting not doing anything

[ayur666]

Hi, I'm on sublimetext3, with mavensmate, windows10, trying to get the formatter to put brackets on a new line rather than at the end of a statement like so:
if(argument)
{
code
}

currently it's doing
if(argument){
code
}

I've selected the allman style, but it just doesn't do anything and I don't know why.

"options_default": {
// Default bracket style
// Can be one of "allman", "bsd", "break", "java", "attach", "kr", "k&r",
// "k/r" "stroustrup", "whitesmith", "banner", "gnu", "linux", "horstmann",
// "1tbs", "otbs ", "google", "pico", "lisp", "python", "vtk", or null
// for default.
"style": "allman",
