The compilation database is a JSON file named “ compile_commands.json” which lives at I put that in quotes because, although the language server is pre-installed and pre-configured:Ĭlangd relies on a “compilation database” which provides necessary informationĪbout compiler options and lists the files relevant to the current project workspace. C-family languages and Swift “work” out of the box if you have Xcode installed. If you’re using a custom language, you can write your own LSP server.Īs you might expect, to get this working requires installing a server package for each language (links here). ![]() It uses an open protocol that’s implemented by various open-source language implementations. In a way, this is better because it also works with languages not supported by Xcode. I’d long hoped that Xcode would add an API to make its indexing information available to external editors. I’m really excited about this, as it enables all sorts of IDE-type features. If a language server reports issues (errors and warnings) for a file in which you’re editing, ranges corresponding to those issues get highlighted according to their severity, and the corresponding lines are highlighted in the line number bar.Ĭommand-double-click on a word will direct the request to an appropriate language server and perform the equivalent of “Go to Definition”, if possible. If a language server supports the “signature help” feature, BBEdit enables the “Show Parameter Help” command on the Edit menu choosing this will open a panel providing assistance for filling in function parameters at the current insertion point (if applicable). (occasionally referred to here as “LSP”, not to be confused withĬompletions supplied by the language server are significantly more accurate and complete than those available using the built-in mechanisms.
