Language Server Protocol implementation for working with Turtle and other RDF technologies

Turtle Language Server

This is a LSP server implementation for RDF graphs serialized as Turtle.

Install with: pip install turtle_language_server

Commands and Features

• Use the loadGraphs command to pull in the graph definitions listed as prefixes in your Turtle file:

  # caches graphs in-memory for NeoVim session
  :CocCommand loadGraphs
  

  # overrides cache and pulls graphs anyway
  :CocCommand loadGraphs force
  

• syntax checking your Turtle file (including undefined namespaces)

• auto-complete when adding statements to the file (relies on loadGraphs)

TODOs:

• verify shapes and add validation information to UI

Setup With NeoVim and CoC

If you are using coc.nvim, you can configure the language server as follows:

1. Make sure Vim correctly detects turtle files and sets the filetype. One way to achieve this is by adding the following line to your .vimrc or init.nvim:

   au BufRead,BufNewFile *.ttl set filetype=turtle

2. Modify your CoC settings to use the turtle_language_server when you open a Turtle file.

   1. First, run :CocConfig or edit coc-settings.json
   2. Add the following (merge with existing keys in "languageserver" if needed):

      {
        "languageserver": {
          "turtle": {
            "command": "turtle_langserver",
            "filetypes": ["ttl", "turtle"]
          }
        }
      }
