It is important to define the buffer local backend variables in a config.el otherwise it is not available in the layer configuration if the auto-completion layer is removed. There were also some issues by hiding the explicit configuration of company inside a macro, for instance helm-spacemacs is unable to display the company package configured in a given layer if the auto-completion layer is removed. |

C/C++ contribution layer for Spacemacs
Table of Contents
Description
This layer adds configuration for C/C++ language as well support for CMake scripts.
Features
- Support syntax checking with Clang.
- Display function or variable definition at the bottom.
- Display current function cursor is in at the top. See this page for demos in some programming languages.
- Support common refactoring with semantic-refactor. See this page for demonstration of refactoring features.
Clang Fanciness
This layer adds some fancy improvements to company-clang.
It includes a hook to load a projects .clang_complete file, which is
just a text file with one clang flag per line, a format also used by
other text editor clang plugins.
Not only does this allow proper autocomplete on projects with extra includes and flags, but there is also support for flycheck so that it doesn't complain about missing header files.
