Hey there Maciej!
I've been using clangd with no problems, the indexing is expensive but
after that it's a breeze. Are you cleaning your tree very often?
(...)
local lspconfig = require("lspconfig")
local get_servers = require("mason-lspconfig").get_installed_servers
for _, server_name in ipairs(get_servers()) do
if server_name == "clangd" then
local compile_commands = vim.fn.getcwd() .. "/compile_commands.json"
if vim.fn.filereadable(compile_commands) == 1 then
lspconfig[server_name].setup({
on_attach = LSPAttach,
capabilities = LSPCapabilities,
offset_encoding = "utf-16",
})
end
else
lspconfig[server_name].setup({
on_attach = LSPAttach,
capabilities = LSPCapabilities,
offset_encoding = "utf-16",
})
end
end
