Move company and auto-complete to a common layer. They are not enabled globally anymore, each mode using them must explicitly declare a hook. Only one frontend is supported for a given mode, we have to choose the best between the two. Only one key binding to toggle auto-completion on `SPC t a` no matter if it is company or auto-complete. The lighter in the mode-line is Ⓐ for both frontends.

## 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][stickyfunc-demos]
|
|
for demos in some programming languages.
|
|
- Support common refactoring with [semantic-refactor][]. See [this page][srefactor-demos]
|
|
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.
|
|
|
|
