## config
`clang-format version 17.0.6`
```
---
BasedOnStyle: LLVM
---
Language: Cpp
UseTab: AlignWithSpaces
IndentWidth: 4
TabWidth: 4
AlignAfterOpenBracket: Align
# this causes the buggy continuation indents
ColumnLimit: 0
---
```
tabs are highlighted with `╺╴╴╴`.
## input (and expected output)
```cpp
int main() {
╺╴╴╴std::cout << "stuff"
╺╴╴╴ << a
╺╴╴╴ << " gnampf";
╺╴╴╴auto chain = a.b()
╺╴╴╴╺╴╴╴.c()
╺╴╴╴╺╴╴╴.d();
╺╴╴╴auto stuffstuff0 = stuff(blsf, eriw);
╺╴╴╴auto stuffstuff1 = stuff(blsf,
╺╴╴╴ eriw);
╺╴╴╴auto stuffstuff2 = stuff(
╺╴╴╴╺╴╴╴bla,
╺╴╴╴╺╴╴╴iee
╺╴╴╴);
╺╴╴╴auto stuffstuff3 = stuff(
╺╴╴╴╺╴╴╴bla,
╺╴╴╴╺╴╴╴iee
╺╴╴╴).trailcall();
}
```
## output after formatting
```cpp
int main() {
// bug 1: should have alignment spaces to line up <<
╺╴╴╴std::cout << "stuff"
╺╴╴╴╺╴╴╴╺╴╴╴ << a
╺╴╴╴╺╴╴╴╺╴╴╴ << " gnampf";
// bug 2: should just be continuation indent (or a new config option)
╺╴╴╴auto chain = a.b()
╺╴╴╴ .c()
╺╴╴╴ .d();
// correct
╺╴╴╴auto stuffstuff0 = stuff(blsf, eriw);
// correct
╺╴╴╴auto stuffstuff1 = stuff(blsf,
╺╴╴╴ eriw);
// correct, but needs new config item to allow the ) on the next line.
╺╴╴╴auto stuffstuff2 = stuff(
╺╴╴╴╺╴╴╴bla,
╺╴╴╴╺╴╴╴iee);
// bug 3: indent of bla/iee should be just one continuation indent, and .trailcall() should not be indented (probably bug 2)
╺╴╴╴auto stuffstuff3 = stuff(
╺╴╴╴╺╴╴╴╺╴╴╴╺╴╴╴╺╴╴╴╺╴╴╴ bla,
╺╴╴╴╺╴╴╴╺╴╴╴╺╴╴╴╺╴╴╴╺╴╴╴ iee)
╺╴╴╴ .trailcall();
}
