After enabling this feature I am not able to use clang-format to format files

See original GitHub issue

Issue Type: Bug

Enabling this extension stops VS Code from formatting my files when using clang-format. It works perfectly fine when using Intellisense. It also works fine when enabling the extension for the first time in one VS Code session. But if the extension is enabled and I restart VS code then formatting stops working. There is a quick status message at the bottom saying extension c/c++ cannot format .....myFileName...

The C/C++ extension doesn’t output any logs in the output tab. I assume that has to do with the fact that Intellisense is disabled after clangd is enabled.

Clangd doesn’t output any additional logs in the output tab when formating a file fails.

Extension version: 0.1.11 VS Code version: Code 1.56.2 (054a9295330880ed74ceaedda236253b4f39a335, 2021-05-12T16:45:26.313Z) OS version: Linux x64 5.12.5-arch1-1

This one’s not clangd’s fault. Think you’ve got a setting in your config something like

    "[cpp]": {
        "editor.defaultFormatter": "ms-vscode.cpptools"

which tells it to use cpptools (the MS C/C++ extension) for code formatting. As you surmise, for some reason cpptools doesn’t do code formatting if its intellisense is disabled (I even raised a bug for it the other day!). If you remove that setting, clangd will do the formatting using its own copy of clang-format.

What is the best way to use clangd as a language server and another clang-format for formatting? Is that possible?

That’s going to be client-dependent, but e.g. with VSCode, you can install the xaver.clang-format extension and configure that to be your default formatter (that extension in turn has a setting to point it to a clang-format executable).
