Theia - Cpp Extension

This extension uses Clangd to provide LSP features.

To install Clangd on Ubuntu 18.04:

$ wget -O - https://apt.llvm.org/llvm-snapshot.gpg.key | sudo apt-key add -
$ echo "deb http://apt.llvm.org/bionic/ llvm-toolchain-bionic main" | sudo tee /etc/apt/sources.list.d/llvm.list
$ sudo apt-get update && sudo apt-get install -y clang-tools-8
$ sudo ln -s /usr/bin/clangd-8 /usr/bin/clangd

See here for detailed installation instructions.

To get accurate diagnostics, it helps to:

Have the build system of the C/C++ project generate a compile_commands.json file.
Point Clangd to the build directory containing said compile_commands.json.
Set path to Clangd executable.
Set arguments to pass to clangd when starting the language server.

#2 can be done using the cpp.buildConfigurations preference. In your home or your project .theia/settings.json, define one or more build configurations:

{
    "cpp.buildConfigurations": [{
        "name": "Release",
        "directory": "/path/to/my/release/build"
    },{
        "name": "Debug",
        "directory": "/path/to/my/debug/build"
    }]
}

You can then select an active configuration using the C/C++: Change Build Configuration command from the command palette.

#3 can be done either by:

Setting CPP_CLANGD_COMMAND environment variable
Adding cpp.clangdExecutable preference in your home or your project .theia/settings.json:
```
  {
      "cpp.clangdExecutable": "/path/to/my/clangd/executable"
  }
```
Adding clangd to system path. Default value of executable path is set to clangd

#4 can be done either by:

Setting CPP_CLANGD_ARGS environment variable
Adding cpp.clangdArgs preference in your home or your project .theia/settings.json:
```
  {
      "cpp.clangdArgs": "list of clangd arguments"
  }
```
