Getting started

You can use Qlue-ls with any tool that has a lsp-client or as standalone formatter..

Local Installation

Qlue-ls is available on crate.io:

cargo install qlue-ls

And on PyPI:

pipx install qlue-ls

You can also build it from source:

git clone https://github.com/IoannisNezis/Qlue-ls.git
cd Qlue-ls
cargo build --release --bin qlue-ls

Web Usage

If you want to connect from a web-based-editor, you can use this package as well. For this purpose this can be compiled to wasm and is available on npm:

npm i qlue-ls

You will have to wrap this in a Web Worker and provide a language server client. There will be more documentation on this in the future...

Until then you can check out the demo in ./editor/

Editor Setup

Here are a few common editors:

Neovim

After you installed the language server, add this to your init.lua:

vim.lsp.config('qlue-ls',{
  filetypes = {'sparql'},
  cmd = { 'qlue-ls', 'server' },
  root_dir = vim.fn.getcwd(),
  -- Set any keymaps you want to use with Qlue-ls
  on_attach = function(client, bufnr)
    vim.keymap.set('n', '<leader>f', vim.lsp.buf.format, { buffer = bufnr, desc = 'LSP: ' .. '[F]ormat' })
  end,
}
)

vim.lsp.enable({'qlue-ls'})

With the above setup, Qlue-ls will load configuration from a file called qlue-ls.{yml, toml} in the working directory neovim is launched from. All file formats supported by the config create are valid.

Open a .rq file and check that the buffer is attached to the server:

:checkhealth lsp
