Coding Style

Tabs and indentation

No tab characters should be used. Use 4 spaces instead of tabs.

Identifiers

• Class names: CamelCase with uppercase first letter
• Method and property names: camelCase with lowercase first letter
• Private and protected class and struct fields: _camelCase prepend with underscore
• Signal names: camelCase
• Enum member names: camelCase

Spaces

Always put space after comma or semicolon if there are more items in the same line

auto list = [1, 2, 3, 4, 5];

Usually no spaces after opening or before closing [] (). Spaces may be added to improve readability when there is a sequence of brackets of the same type.

auto y = (x * x + ( ((a - b) + c) ) * 2);

Use spaces before and after == != && || + - * / etc.

Brackets

Use curly braces for if, switch, for, foreach - preferable placed on the same lines as keyword:

if (a == b) {
    //
} else {
    //
}

foreach (item; list) {
    writeln(item);
}

Cases in switch should be intended:

switch(action.id) {
    case 1:
        break;
    default:
        break;
}
