I haven't had the time to work on this in a long while - StaySail Systems has massively improved this work with CDragon and I'd highly recommend you use their extension instead
This extension provides very bare-bones integration with clangd to Nova - it's basically the example wrapper with a few tweaks.
In order to use this extension, you need to supply a version of clangd - its path can be specified in the global settings pane for this extension if required.
There are two simple routes that can get you started:
Open a terminal and run
# brew install llvm
This will install a copy of clangd and symlink it into /usr/bin
Go to https://clangd.llvm.org in your web browser and download the Standalone .zip release. Extract this to any location on your mac and set the path in the extension preferences.
The plugin will start when editing a C++ source file. In order to provide project-context specific information, your project will need to provide a compile_commands.json file - CMake can generate one for you by passing the CMAKE_EXPORT_COMPILE_COMMANDS variable when generating your project. More information can be found at https://clang.llvm.org/docs/JSONCompilationDatabase.html
The directory where your compile_commands.json file is stored can be specified in global or project preferences, if it is not in the root oft he project directory
To configure global preferences, open Extensions → Extension Library... then select C++'s Preferences tab.
You can also configure preferences on a per-project basis in Project → Project Settings...
I would eventually like to make this generally more configurable, and perhaps provide some build/debug functionality.
If you have a better grasp of Nova's extension API feel free to open a pull request, I don't have a tonne of time to work on this by myself so any help from the community is appreciated.
