Configuration

1. Create a symlink in the root of your WebKit source directory:

   $ ln -s WebKitBuild/GTK/Release/compile_commands.json compile_commands.json
   

   Replacing GTK with WPE if you are commonly building the WPE port.

2. In your IDE set the clangd path to <WebKitSourceDirectory>/Tools/flatpak/webkit-clangd.
3. Make sure that the clangd arguments include the --enable-config and the --gtk or --wpe options.

Vim Example

For instance, when configuring vim's coc via :CocLocalConfig you write:

{
    "clangd.arguments": [
        "--enable-config",
        "--gtk"
    ],
    "clangd.path": "/home/user/WebKit/Tools/flatpak/webkit-clangd"
}
