Boost.GIL Clang-Format

This is an example of .clang-format file which offers good enough configuration and may be useful when writing code for GIL, not required though.

This is not a complete configuration!

It does not cover all the recommended or preferred ways of formatting the code for GIL. It may be necessary to manually tweak the formatting generated by this .clang-format file. For example, there is a bug in clang-format that does not allow spacing and breaking trailing return types properly (here and here). More in details can be found in the brainstorm of .clang-format proposal.

It has been successfully used with clang-format 8 or later.

If you wish to use this file with clang-format, copy it to the root directory of GIL sources, to libs/gil/.clang-format.
