ide-clangd

Provides C and C++ language support for Atom using Clangd language server

About

This plugin only provides some of the functionality designated by the language server protocol. This plugin currently enables many of the features supported by Clangd:

• Diagnostics (errors, warnings, info)
• Code Formatting
• Completion
• Fix-its
• Function signature help
• Document highlights
• Go To Definition (it will go to the declaration, but not the definition)
• Rename (not yet supported by Atom)

All contributions and feedback are appreciated.

Requirements

• Atom 1.21-beta
• atom-ide-ui atom plugin
• Clangd executable installed in your path (prebuilt binaries)

Additional Notes

compile_commands.json

• In order to make this plugin work effectively, you need to generate a compile_commands.json file in a place where clangd can find it (project root). CMake is currently your best bet for making that happen. If you're doing an out-of-source build and you're already in your project/build directory, the CMake command to generate compile_commands.json along with your project looks like this: cmake .. -DCMAKE_EXPORT_COMPILE_COMMANDS=ON

Clangd won't see your compile_commands.json file if you do an out of source build like this, though. The best solution I've come up with so far is to symlink compile_commands.json from my build directory to my project root with ln -s build/compile_commands.json .

Areas of interest

• clang-format supports a plethora of formatting options. Need to figure out how to use .clang-format options with Clangd.
• Automatic installation of Clangd
