<div>
<pre>With the addition of the BraceWrapping/AfterCaseLabel option the default
behavior has changed and it seems impossible to produce a .clang-format file
which produces consistent output across versions.
The following .clang-format file produces different output depending on the
clang-format version.
---
BreakBeforeBraces: Custom
BraceWrapping:
AfterControlStatement: true
AfterFunction: true
$ clang-format --version
clang-format version 7.0.0 (tags/RELEASE_700/final)
$ clang-format <<< 'switch (42) { default:{ break; } }'
switch (42)
{
default:
{
break;
}
}
$ clang-format --version
clang-format version 9.0.0 (tags/RELEASE_900/final)
$ clang-format <<< 'switch (42) { default:{ break; } }'
switch (42) {
default: {
break;
}
}
Note that adding ` AfterCaseLabel: true` restores the old behavior however
having this line stops older versions of clang-format from running.
`YAML:4:19: error: unknown key 'AfterCaseLabel'`</pre>
