Description

lang#c layer provides c/c++/object-c language support for SpaceVim.

Install

To use this configuration layer, update the custom configuration file with:

[[layers]]
  name = "lang#c"

Features

• code completion
• syntax checking
• formatting

Configuration

• enable_clang_syntax_highlight (boolean)

Enable/Disable clang based syntax highlighting.

• clang_executable (string)

Set the path to the clang executable

• libclang_path (string)

The libclang shared object (dynamic library) file path. By default it is empty.

• clang_std (dict)

A dict containing the standards you want to use. The default is:

{
    "c": "c11",
    "cpp": "c++1z",
    "objc": "c11",
    "objcpp": "c++1z",
}

• clang_flag (list)

You should be able to just paste most of your compile flags in there. You can also use a list ['-Iwhatever', ...] when loading this layer.

Here is an example how to use above options:

[[layers]]
  name = "lang#c"
  clang_executable = "/usr/bin/clang"
  clang_flag = ['-I/user/include']
  [layer.clang_std]
    c = "c11"
    cpp = "c++1z"
    objc = "c11"
    objcpp = "c++1z"

Instead of using clang_flag options, You can also create a .clang file in the root directory of your project. SpaceVim will load the options defined in .clang file. For example:

-std=c11
-I/home/test

Note: If .clang file contains std configuration, it will override clang_std layer option.
