Neovim support

[liketoeatcheese]

Hey mate,

I saw in your description that it supports nvim. Is there documentation somewhere on how to set it up? Great stuff :)

Hi,

jinja-lsp should be installed on your path.

init.lua:

local nvim_lsp = require('lspconfig')
local configs = require('lspconfig.configs')
if not configs.jinja_lsp then
configs.jinja_lsp = {
  default_config = {
    cmd = { 'PATH/jinja-lsp'},
    filetypes = {'jinja', 'rs'},
    root_dir = function(fname) 
      return lspconfig.util.find_git_ancestor(fname)
    end,
    settings = {
      templates = './TEMPLATES_DIR',
      backend = {'./BACKEND_DIR'},
      lang = "rust"
    }
  }
}
end

nvim_lsp.jinja_lsp.setup{}

Lsp should be available for Rust files too.

I haven't used Neovim in while now, maybe they changed how to add custom language server.

[liketoeatcheese]

Righttt. Yea, that makes sense now. Thanks for replying! And I assume the templates dir would be the directory of the templates starting from the project’s root and the backend dir would be the src folder?

[uros-5]

Yeah, correct. In configuration, backend is array(table) of all directories that can contain variables, functions, filters for templates. It's array because you may want to use cargo-workspaces. Check example.

[liketoeatcheese]

Amazing. I got it set up. Thanks again! I appreciate it :)

Hi uros, I can see the LSP server was attached to the buffer, but I'm not sure if it's working. I couldn't see the suggestions and all the fancy stuff that was showcased. Is there a way to confirm or do I need to do anything to trigger it? Note that I also tried your example folder but it didn't work as well.

local lspconfig = require("lspconfig")
local configs = require("lspconfig.configs")
if not configs.jinja_lsp then
configs.jinja_lsp = {
  default_config = {
      cmd = { "/home/wpham/.cargo/bin/jinja-lsp" },
      filetypes = { "html", "jinja", "rs" , "css"},
      root_dir = function(fname)
          print(fname)
          return lspconfig.util.find_git_ancestor(fname)
      end,
      settings = {
          templates = "./templates",
          backend = { "./src" },
          lang = "rust",
      },
  },
}
end

lspconfig.jinja_lsp.setup({})

When I do LspInfo:

Happy to provide any extra info if needed

[uros-5]

Try this:

vim.filetype.add {
  extension = {
    jinja = 'jinja',
    jinja2 = 'jinja',
    j2 = 'jinja',
  },
}

-- uncomment this part if language server is not working
-- vim.lsp.set_log_level("debug")

local nvim_lsp = require('lspconfig')
local configs = require('lspconfig.configs')

-- try to remove this if statement at the moment and leave only that inner block
-- if it succeeds then add it again

if not configs.jinja_lsp then
configs.jinja_lsp = {
  default_config = {
    name = "jinja-lsp",
    cmd = { "/home/wpham/.cargo/bin/jinja-lsp" },
    filetypes = { "html", "jinja", "rs" , "css"},
    root_dir = function(fname)
      return "."
      --return nvim_lsp.util.find_git_ancestor(fname)
    end,
    init_options = {
      templates = './templates',
      backend = { './src' },
      lang = "rust"
    }
  }
}
end

nvim_lsp.jinja_lsp.setup {}

The lsp does attach to the buffer, but it's not providing suggestions, etc... Attached is the video showing the example project

[uros-5]

Replace your current configuration with one I mentioned in previous comment.

[liketoeatcheese]

Noiceee! I got it working <3 Thanks for that!

[zilahir]

Heyo!

unfortunately, i have the same issue, i cant seem to get this working. use the snippet you provided @uros-5 , the LSP gets attached to the buffer, but nothing really happening, no syntax highlight etc.

i am using a lazyvim, and created a file for the config. However, i needed to add a

return {}

at the end of the file, otherwise it failes as i am not returning a table, but a boolean.

Any tips would be greatly appreciated! 🙏

Hi. I'm using lazy.vim as well, but I setup the LSP by leveraging the nvm-lsconfig plugin.However the LSP doesn't seem to attached to the .html buffer, could you please provide your config file? Any tips would be greatly appreciated! 🙏
