What if I don't find my LSP in MASON about lsp-zero.nvim HOT 3 CLOSED

Make sure you are using the branch v3.x of lsp-zero.

from lsp-zero.nvim.

Is it 0 to LSP tutorial? That video uses an old version of lsp-zero. Make sure you are using lsp-zero version 3 (use the branch v3.x). You can use the command :help lsp-zero-version to check which version you are using.

If a language server is not available in mason, you have to install it manually. After that, if the language server is supported by lspconfig then just call the setup function for it. The list of supported servers is here: server_configurations.md.

Since sourcekit is already supported by lspconfig this should work.

local lsp_zero = require('lsp-zero')

lsp_zero.on_attach(function(client, bufnr)
  lsp_zero.default_keymaps({buffer = bufnr})
end)

require('lspconfig').sourcekit.setup({})

If the language server is not supported by lspconfig you can still add a configuration to make it work. There is a section in the documentation that describes how to do it: Custom servers.

That was helpful, thanks!

Now I'm presenting this issue:

Error detected while processing /Users/user-name/.config/nvim/after/plugin/lsp.lua:
E5113: Error while calling lua chunk: /Users/user-name/.config/nvim/after/plugin/lsp.lua:86: attempt to call field 'cmp_format' (a nil value)

It looks like when I try to set up cmp with the formatting value, lsp-zero.cmp_format() is giving a nil value.
