Completion and Diagnostic for C/C++/Objective-C using Clang command.
Clang project officialy starts to implement Language Server named clangd. (https://github.com/llvm-mirror/clang-tools-extra/tree/master/clangd)
This extension was renamed to C/C++ Clang Command Adapter to avoid confusion, because this extension is unofficial and only parse output of clang command.

- Configure the
PATH
environment variable so that you can executeclang
command.- or specify
clang.executable
configuration (See the next section for detail)
- or specify
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
ClangCommandAdapter: Show Executable and Compile Options
: Showing Clang executable and compile options for the active editor.ClangCommandAdapter: Trust Workspace
: Trust the current workspace. (see #Security)ClangCommandAdapter: Untrust Workspace
: Untrust the current workspace. (see #Security)
The following settings may cause security issue, if you are opening a malicious workspece.
clang.executable
: Arbitrary executables specified in the workspace-level setting will be executed.clang.cflags
,clang.cxxflags
,clang.objcflags
: Clang command is executed with artibrary options specified in the workspace-level setting.
Therefore, these workspace-level settings are disabled by default.
- To enable these workspace-level settings, please trust the workspace from dialog that appears when you open the file.
- To change trust/untrust status of the current workspace, please use
ClangCommandAdapter: Trust Workspace
orClangCommandAdapter: Untrust Workspace
.
- Regexp for parsing completion results of Clang is based autocomplete-clang.
