Use Visual Studio Code on Chromium code base

Visual Studio Code (Wikipedia) is a multi-platform code editor that is itself based on Electron which is based on Chromium. Visual Studio Code has a growing community and base of installable extensions and themes. It works without too much setup.

Install extensions

ctrl+p paste ext install cpptools you-complete-me then enter. For more extensions: https://marketplace.visualstudio.com/search?target=vscode

Highly recommend you also install your favorite keymap.

An Example to install eclipse keymaps ext install vscode-eclipse-keybindings. You can search keymaps here. https://marketplace.visualstudio.com/search?target=vscode&category=Keymaps

Settings

Open Settings File/Code - Preferences - Settings and add the following settings.

{
  "editor.tabSize": 2,
  "editor.rulers": [80],
  // CPP
  "C_Cpp.clang_format_path": "<your_depot_tools_path>/clang-format",
  "C_Cpp.clang_format_fallbackStyle": "Chromium",
  // Exclude
  "files.exclude": {
    "**/.git": true,
    "**/.svn": true,
    "**/.hg": true,
    "**/.DS_Store": true,
    "**/out": true
  },
  // YCM
  "ycmd.path": "<your_ycmd_path>",
  "ycmd.global_extra_config": 
      "<your_chromium_path>/src/tools/vim/chromium.ycm_extra_conf.py",
  "ycmd.confirm_extra_conf": false,
  "ycmd.use_imprecise_get_type": true
}

Install auto-completion engine(ycmd)

$ git clone https://github.com/Valloric/ycmd.git ~/.ycmd
$ cd ~/.ycmd
$ ./build.py --clang-completer

Work flow

ctrl+p open file.
ctrl+shift+o goto symbol. ctrl+l goto line.
ctrl+` toggle terminal.

Tips

On laptop

Because we use ycmd to enable auto completion. we can disable CPP autocomplete to save battery. "C_Cpp.autocomplete": "Disabled"
