Other build systems, using BearĬompile_commands.json file by recording a complete build.įor a make-based build, you can run make clean bear - make to generate the Refer to instructions in the project README it is intended for use with clangd. Ln -s ~/myproject-build/compile_commands.json ~/myproject/īazel can generate this file via this extractor extension. If your project builds with CMake, it can generate this file. $SRC/gui/build/, $SRC/, $SRC/build/, … CMake-based projects This file provides compile commands for every source file in a project.Ĭlangd will look in the parent directories of the files you edit looking for it,įor example, if editing $SRC/gui/window.cpp, we search in $SRC/gui/, (This is just a fact of life in C++, source files are not self-contained).īy default, clangd will assume your code is built as clang some_,Īnd you’ll probably get spurious errors about missing #included files, etc. To understand your source code, clangd needs to know your build flags. Support and most faithfully demonstrates what clangd can do. ![]() If you don’t have strong feelings about an editor, we suggest you try out There is a directory of LSP clients at .Ī generic client should be configured to run the command clangd, andĬommunicate via the language server protocol on standard input/output. Command-line flags and alternate clangd binary: inside the.Settings can be tweaked under Preferences–> Package Settings–> LSP. code completion (a bit noisy due to how snippets are presented).The LSP package has excellent support for all most clangd features, including: Open a C++ file, and you should see diagnostics and completion: Press Ctrl-Shift-P and select LSP: Enable Language Server Globally. Press Ctrl-Shift-P and select Package Control: Install Package. Select Tools–> Install Package Control (if you haven’t installed it yet). Tomv564/LSP works with clangd out of the box. Alternate clangd binary: set the clangd.path string in settings.json.Command-line flags: these can be passed in the clangd.arguments array.In the dropdown of the Output panel ( View -> Output). Debug logs: when clangd is running, you should see “Clang Language Server”.find symbol in file ( Ctrl-P or workspace ( Ctrl-P #foo).find declarations, references, and definitions.Vscode-clangd has excellent support for all clangd features, including: You should get rich code completions including e.g. The Microsoft C/C++ extension is not installed).Īfter restarting, you should see red underlines underneath errors, and To eglot-server-programs, add ("/path/to/clangd" "-log=verbose") etc.Ĭhoose View –> Extensions, then search for “clangd”. Command-line flags and alternate binary: instead of adding "clangd".Debug logs: available in the EGLOT events buffer.You can install it with M-x package-install RET company RET, and enable it find definitions and references ( M-x xref-find-definitions etc)Įglot does have basic integration with company-mode, which provides a more.code completion, enhanced by company-mode, see below.( require 'eglot ) ( add-to-list 'eglot-server-programs ' (( c++-mode c-mode ) "clangd" )) ( add-hook 'c-mode-hook 'eglot-ensure ) ( add-hook 'c++-mode-hook 'eglot-ensure )Īfter restarting you should see diagnostics for errors in your code, and M-xĮglot supports many of clangd’s features, with caveats: ![]() ![]() We recommend changing a couple of YCM’s default settings. This is not on by default, you must install it with Here are some plugins we know work well with clangd: VimĬlangd support. Should work with any of them, though feature set and interface may vary. Language Server plugins are available for many editors. If you live on the bleeding edge, snapshot pre-releases are built weekly andĪvailable on the github releases page. You can also download binaries directly for macOS, windows, and Linux (x86-64): Package, or in the full llvm distribution.įor some platforms, binaries are also available at. Most distributions include clangd in a clangd package, in a clang-tools Sudo update-alternatives -install /usr/bin/clangd clangd /usr/bin/clangd-12 100
