The original example demonstrating the formatting issue
The following example:
TEST_CASE("Test 1") {
#ifndef MY_DEF
{
int b = 0;
}
#endif
}
TEST_CASE("Test 2") {
}
gets formatted by the default clang-format version 10.0.0 as follows:
TEST_CASE("Test 1"){
#ifndef MY_DEF
{int b = 0;
}
#endif
}
TEST_CASE("Test 2") {}
Note that block inside the `#ifdef` is ruined.
TEST_CASE is a special macro from <a href="https://github.com/onqtam/doctest">https://github.com/onqtam/doctest</a> which
creates and registers a test case with a specific name and body.
If I replace `TEST_CASE("Test 1")` with `void foo()`, the problem persists.
However, any of the following changes make the problem go away:
1. Remove #ifndef
2. Replace `TEST_CASE("Test 2")` with `void bar()`.
3. Add `int x;` on a separate line immediately before `TEST_CASE("Test 2")`</pre>
