Detailed Description

The current state when indenting a unwrapped line.

As the indenting tries different combinations this is copied by value.

Column

unsigned clang::format::LineState::Column

The number of used columns in the current line.

Definition at line 413 of file ContinuationIndenter.h.

FirstIndent

unsigned clang::format::LineState::FirstIndent

The indent of the first token.

Definition at line 454 of file ContinuationIndenter.h.

IgnoreStackForComparison

bool clang::format::LineState::IgnoreStackForComparison

Ignore the stack of ParenStates for state comparison.

In long and deeply nested unwrapped lines, the current algorithm can be insufficient for finding the best formatting with a reasonable amount of time and memory. Setting this flag will effectively lead to the algorithm not analyzing some combinations. However, these combinations rarely contain the optimal solution: In short, accepting a higher penalty early would need to lead to different values in the ParenState stack (in an otherwise identical state) and these different values would need to lead to a significant amount of avoided penalty later.

FIXME: Come up with a better algorithm instead.
