Completion and Diagnostic for C/C++/Objective-C using Clang

• Install Clang
  • For Max OS X, Clang is installed with XCode Command Line Tools and PATH is configured automatically.
• Configure the PATH environment variable so that you can execute clang command.
  • or specify clang.executable configuration (See the next section for detail)

You can use configuration interface of Visual Studio Code. (Press F1 and type User Settings or Workspace Settings)

• clang.executable: Clang command or the path to the Clang executable (default: clang)
• clang.cflags, clang.cxxflags, clang.objcflags: Compiler Options for C/C++/Objective-C

• clang.completion.enable: Enable/disable completion feature (default: true)
• clang.completion.maxBuffer: Tolerable size of clang output for completion (default: 8 * 1024 * 1024 bytes)
• clang.completion.triggerChars: Trigger completion when the user types one of the characters (default: [".". ":", ">"])

• clang.diagnostic.enable: Enable/disable diagnostic feature (default: true)
• clang.diagnostic.maxBuffer: Tolerable size of clang output for diagnostic. (default: 256 * 1024 bytes)
• clang.diagnostic.delay: The delay in millisecond after which diagnostic starts (default: 500)

Configurations support some variables which are available in tasks.json. They can be used inside of strings (e.g. "-I${workspaceRoot}/include")

• ${workspaceRoot}
• ${cwd}
• ${env.ENVIRONMENT_VARIABLE}

Since version 0.2.0, clang.diagnosticDelay, clang.enableCompletion, clang.enableDiagnostic is deprecated. Please update as follows:

• clang.enableCompletion -> clang.completion.enable
• clang.enableDiagnostic -> clang.diagnostic.enable
• clang.diagnosticDelay -> clang.diagnostic.delay

• Show Executable and Compile Options: Showing Clang executable and compile options for the active editor.

• Regexp for parsing completion results of Clang is based autocomplete-clang.
