Use Vim as a C/C++ IDE

This is a general guide for using SpaceVim as a C/C++ IDE, including layer configuration and usage. Each of the following sections will be covered:

• Enable language layer
• code completion
• alternate file jumping
• code running
• code format
• REPL support <!-- vim-markdown-toc --> ### Enable language layer

To add C/C++ language support in SpaceVim, you need to enable the lang#c layer. Press SPC f v d to openSpaceVim configuration file, and add following configuration:

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

for more info, you can read the lang#c layer documentation.

code completion

By default the autocomplete layer has been enabled, so after loading lang#c layer, the code completionfor C/C++ language should works well.

alternate file jumping

To manage the alternate file for a project, you may need to create a .project_alt.json file in the root of yourproject.

for exmaple, add following content into the .project_alt.json file:

{
  "*.c": {"alternate": "{}.h"},
  "*.h": {"alternate": "{}.c"}
}

with this configuration, you can jump between the alternate file via command :A

code running

The default code running key binding is SPC l r. It will compile and run current file asynchronously.And the stdout will be shown on a runner buffer.

code format

The format layer use neoformat as default tool to format code, it will format current file.And the default key binding is SPC b f.

[[layers]]
  name = "format"

REPL support

Start a igcc inferior REPL process with SPC l s i. After the REPL process being started, you cansend code to inferior process, all key bindings prefix with SPC l s, including sending line, sending selection or evensend whole buffer.
