Using autocomplete from html LSP

b-m-f commented 2 months ago

According to https://www.andersevenrud.net/neovim.github.io/lsp/configurations/html/ it is necessary to setup up the vscode-langservers-extracted with

--Enable (broadcasting) snippet capability for completion
local capabilities = vim.lsp.protocol.make_client_capabilities()
capabilities.textDocument.completion.completionItem.snippetSupport = true

require'lspconfig'.html.setup {
  capabilities = capabilities,
}

In order to get auto-completion working for HTML.

Is there a possibility to add an option for this on https://nix-community.github.io/nixvim/plugins/lsp/servers/html/index.html .

Maybe there is also another way to do this in my user config? Unfortunately I have not been able to get this properly setup.

The following should work:

extraConfigLuaPre = ''
  local hmtl_capabilities = vim.lsp.protocol.make_client_capabilities()
  html_capabilities.textDocument.completion.completionItem.snippetSupport = true
'';

lsp = {
  enable = true;
  servers.html = {
    enable = true;
    extraOptions.capabilities.__raw = "html_capabilities";
  };
};

Could you please try it and tell me if it works ?

Hi, thanks for the quick response!

Unfortunately it still does not seem to work. Maybe it has something to do with the luasnip setup mentioned in lspconfig.

Here is where I currently at:
