clangd --version is used to check the version of the Clangd language server.
Here's a breakdown of what it does:
clangd: This is the name of the command or executable. Clangd is a language server for the C and C++ languages. It provides IDE-like features, such as code completion, diagnostic messages, and code navigation, to editors and integrated development environments (IDEs).
--version: This is a command-line option that tells the
clangdexecutable to print its version information. Instead of executing the normal functionality of the
clangdlanguage server, it will only output the version number.
When you run the command
clangd --version in your terminal or command prompt, it will display the version number of the Clangd language server that is installed on your system. This information can be useful for troubleshooting or ensuring that you have the latest version of Clangd installed.
