As written in the clang-format documentation I set the BreakTemplateDeclarations Option to "Yes", but when format my Code it still gets put on the same line. e.g.
template<typename type> class Class{};
instead of
template<typename type>
class Class{};
Is there anything I´m overlooking?
I tried the BreakTemplateDeclarations Option and I also tried the (deprecated) AlwaysBreakTemplateDeclarations Option but none made a difference.
This is my current .clang-format File:

The problem is that you've specified a wrong value true for the key AlwaysBreakTemplateDeclarations (renamed to BreakTemplateDeclarations since clang-format 19). From clang format documentation the possible values are:
Possible values:
- Leave : Do not change the line breaking before the declaration.
- No : Do not force break before declaration.
- MultiLine : Force break after template declaration only when the following declaration spans multiple lines.
- Yes : Always break after template declaration.
So to solve this, change true to Yes.
