vscode-clangd
Provides C/C++ language IDE features for VS Code using clangd:
- code completion
- compile errors and warnings
- go-to-definition and cross references
- include management
- code formatting
- simple refactorings
Setup
clangd
server
clangd
is a language server that must be installed separately, see
getting started.
The vscode-clangd extension will look for clangd
on your PATH (you can change
this in the settings).
Project setup
clangd is based on the clang C++ compiler, and understands even complex C++
code. However, you must tell clangd how your project is built (compile flags).
A compile_commands.json
file
can usually be generated by your build system
(e.g. by setting -DCMAKE_EXPORT_COMPILE_COMMANDS=1
when building with CMake,
or with
many other tools).
It should live at the top of your source tree: symlink or copy it there.
Features
Code completion
Suggestions will appear as you type names, or after .
or ->
.
Because clangd uses a full C++ parser, code completion has access to precise
type information.
Errors, warnings, and clang-tidy
Code errors are shown as you type (both as red squiggle underlines, and in the "Problems" panel). These are the same as produced by the clang compiler, and suggested fixes can automatically be applied.
Most clang-tidy checks are supported (these can be enabled using a .clang-tidy file).
Cross-references
Go-to-definition and find-references work across your code, using a project-wide index.
Press Ctrl-P #
to quickly navigate to a symbol by name.
Include management
Code completion works across your codebase and adds #include
directives where
needed. The •
shows includes that will be inserted.
clangd can also suggest inserting missing #includes, where they cause errors.
Formatting
clangd uses the clang-format
engine. You can format a file or the selection.
When "Format on Type" is enabled in the settings, pressing enter will cause
clangd to format the old line and semantically reindent.
The style used for formatting (and certain other operations) is controlled by the .clang-format file is controlled by the project's .clang-format file.
Refactoring
clangd supports some local refactorings. When you select an expression or declaration, the lightbulb menu appears and you can choose a code action.
Current refactorings include:
- extract variable/function
- expand
auto
types and macros - use raw strings
- rename (bound to
<F2>
, rather than a contextual code action)
