Example

"requireNewlineBeforeBlockStatements": true

Valid

function good()
{
    var obj =
    {
        val: true
    };

    return {
        data: obj
    };
}

if (cond)

    foo();
}

for (var e in elements)
{
    bar(e);
}

while (cond)
{
    foo();
}

Invalid

function bad(){
    var obj = {
        val: true
    };

    return {
        data: obj
    };
}

if (cond){
    foo();
}

for (var e in elements){
    bar(e);
}

while (cond){
    foo();
}

Example

"requireNewlineBeforeBlockStatements": ["if", "else", "for"]

Valid

if (i > 0)
{
    positive = true;
}

if (i < 0)
{
    negative = true;
}
else
{
    negative = false;
}

for (var i = 0, len = myList.length; i < len; ++i)
{
    newList.push(myList[i]);
}

// this is fine, since "function" wasn't configured
function myFunc(x) {
    return x + 1;
}

Invalid

if (i < 0) {
    negative = true;
}

if (i < 0) {
    negative = true;
} else {
    negative = false;
}

for (var i = 0, len = myList.length; i < len; ++i) {
    newList.push(myList[i]);
}

Example

"requireNewlineBeforeBlockStatements": ["function", "while"]

Valid

function myFunc(x)
{
    return x + 1;
}

var z = function(x)
{
    return x - 1;
}

// this is fine, since "for" wasn't configured
for (var i = 0, len = myList.length; i < len; ++i) {
    newList.push(myList[i]);

Invalid

function myFunc(x) {
