Line breaks between function definitions

Question

Is there any way to to automatically insert spaces between function definitions. E.g. my initial sources are:

void
func1()
{
    // func1 body.
}
void
func2()
{
    // func2 body.
}

I would like it to be reformatted to:

void
func1()
{
    // func1 body.
}


void
func2()
{
    // func2 body.
}

And if there are more line breaks, fixed number of them should be kept.

They really need to add this and the ability to insert blank lines in other obvious spots too (e.g. - after variable definitions). — jschultz410, Mar 05 '21 at 22:46
Possible in clang-format 14 - see: https://stackoverflow.com/questions/70732683/how-to-add-blank-lines-between-definitions/70732858 — dluco, Nov 03 '22 at 02:33

As far as I can tell, there's currently no way to force clang-format to insert blank lines between consecutive functions where there currently are none. IMHO this is a huge missing feature.

Is that still not possible in 2020? – Simon Fromme Aug 13 '20 at 03:00

Is that still not possible in 2022? – Saeed Masoomi Feb 18 '22 at 18:22

@SaeedMasoomi It is possible in clang-format ≥ 14. Look at the option _SeparateDefinitionBlocks_. See the documentation [here](https://clang.llvm.org/docs/ClangFormatStyleOptions.html#configurable-format-style-options). – Benoît Dubreuil Jul 14 '22 at 19:52
Current clang-format can insert a single line, but not more. :-/ – barfuin Mar 24 '23 at 09:09

Your best bet is to set 'MaxEmptyLinesToKeep: 2' inside .clang-format file to let clang-format keep 2 lines intact.

As mentioned in this answer with clang-format 14, you can use the following in your config file:

SeparateDefinitionBlocks: Always

The other possible values are Leave, to leave the spacing of definition blocks as-is, or Never, to remove empty lines between definition blocks.

SeparateDefinitionBlocks: Always
