clang-format set short lambda max length?

[Vladislav-Bartalevich]

Is it possible to set a maximum length for short lambdas?

In my project, I have a ColumnLimit: 0 and I want to achieve two things:

• Short lambdas should stay on a single line (so I have AllowShortLambdasOnASingleLine: All)
• Allman-style line breaks before braces for long lambdas (so I have BreakBeforeBraces: Allman)

However, it seems that clang-format uses a default maximum line length of 90 characters for short lambdas. When the line length reaches or exceeds 90, clang-format always introduces a line break.

From a code formatting perspective, I want this:

auto SomeLongOneLiner = [](int SomeLongPieceOfCodeHere) { return SomeLongPieceOfCodeHere != 2; };  // 114 characters

To remain on a single line as shown above. But when I run the formatter, it transforms the code into:

auto SomeLongOneLiner = [](int SomeLongPieceOfCodeHere)
{ return SomeLongPieceOfCodeHere != 2; };
