CMake Language Support

CMake Language Support implements all of your favorite code editor features and is currently available for Visual Studio Code. An interactive preview is available at https://josetr.github.io/cmake-language-support.

Please note that we do our best to get most of the command signatures and parameters by scanning the whole CMake Documentation but it's currently impossible to be 100% accurate due to the nature of the documentation.

Installing .NET 6 Runtime (required)

Automatic

Microsoft's .NET Install Tool for Extension Authors will be used to acquire a .NET Runtime automagically once the extension runs for the first time. If it fails, as seems to be the case for some users, please follow the manual installation instructions.

Manual

• Install .NET Runtime
  • Windows: https://learn.microsoft.com/en-us/dotnet/core/install/windows
  • Linux: https://learn.microsoft.com/en-us/dotnet/core/install/linux
  • macOS: https://learn.microsoft.com/en-us/dotnet/core/install/macos
• Set cmake.languageSupport.dotnetPath to your dotnet executable path (usually C:/Program Files/dotnet/dotnet.exe on Windows)

Configuration

Format Options

• allowOptionalArgumentIndentation

  # false (default) true
  message( message(
   WARNING WARNING
   msg msg # manually added indentation will be kept
  ) )
  

FileAPI (Experimental)

Enables experimental use of https://cmake.org/cmake/help/git-stage/manual/cmake-file-api.7.html in order to provide more accurate results.

• Install Microsoft's CMake Tools extension
• Set cmake.languageSupport.enableFileAPI to true.

Every time CMake Tools configures the active cmake project (usually when you save a CMakeLists.txt file), our cmake-file-api query will be executed and we will be able to:

1. Provide accurate results for:

   • Targets
   • Configurations
   • Toolchains

2. Get the exact cmake files used by the cmake project and parse them all in order to:

   • Search user-declared functions, macros, and variables in all files
   • Enable the following features to work across all of the available files
     • Find All References
     • Go to Definition
     • Workspace Symbols
     • Auto Completion
     • Signature Help
     • Quick Info
