NeoCMake

This is CMake extension for Zed editor. It combines uyha/tree-sitter-cmake and Decodetalkers/neocmakelsp (hence why it's "neo"). The tree-sitter grammar is taken from helix repo.

C++ LSP support (compile_commands.json)

For making clangd and cmake work together do the following:

1. Add set(CMAKE_EXPORT_COMPILE_COMMANDS ON) at the top of the CMakeLists.txt (somewhere below project);
2. Reconfigure cmake project. If everything is correct there should be compile_commands.json file under build directory. I also advise using CXX=clang for better compatibility with clangd;
3. Go to Zed's settings.json: Ctrl+Shift+P open local settings/open default settings;
4. Find lsp section. Inside it paste the following (replace build with your build directory name):

"clangd": {
    "arguments": ["-background-index", "-compile-commands-dir=build"]
}

CMake tasks

Until adding tasks to the extension is possible here are some templates for CMake project. Note that by default all tasks use build directory, but you can change it

Configure

{
  "label": "CMake configure Debug",
  "command": "cmake",
  "args": ["-DCMAKE_BUILD_TYPE=Debug", "-B", "build/"],
  "env": {},
  "use_new_terminal": false,
  "allow_concurrent_runs": false,
  "reveal": "always"
}

Build

{
  "label": "CMake build",
  "command": "cmake",
  "args": ["--build", "build"],
  "env": {},
  "use_new_terminal": false,
  "allow_concurrent_runs": false,
  "reveal": "always"
}

Build and configure

{
  "label": "CMake configure Debug and build",
  "command": "cmake -DCMAKE_BUILD_TYPE=Debug -B build/ && cmake --build build/",
  "args": [],
  "env": {},
  "use_new_terminal": false,
  "allow_concurrent_runs": false,
  "reveal": "always"
}

All together
