[cfe-dev] [clang-format] Trying to use libFormat for code indentation

[Jonas Toth via cfe-dev]

Hi Ivan,


take a look at this one:
https://clang.llvm.org/doxygen/classclang_1_1Lexer.html#a9102a4b3ccbed3505f6d002502193793

The Lexer provides a function that gives the indendation for a line,
given that you seem to know the line of interest you can probably query
the Lexer there.


Best Jonas
