Kedro Language Server: an LSP wrapper for Kedro.

optional arguments:
  -h, --help           show this help message and exit
  --version            display version information and exit
  --tcp                use TCP server instead of stdio
  --host HOST          host for TCP server (default 127.0.0.1)
  --port PORT          port for TCP server (default 2087)
  --log-file LOG_FILE  redirect logs to the given file instead of writing to stderr

Examples:
    Run from stdio: kedro-lsp

Visual Studio Code

To use it with visual studio code, install the Kedro extension from Visual Studio Code Marketplace.

Pycharm

TBD

nvim

To use it with nvim, install lspconfig.

:Plug 'neovim/nvim-lspconfig'

Then add the following config to your vimrc.

lua <<EOF
local configs = require 'lspconfig/configs'

configs.kedro = {
    default_config = {
        cmd = {"kedro-lsp"};
        filetypes = {"python"};
        root_dir = function(fname)
            return vim.fn.getcwd()
        end;
    };
};
EOF

🗒️ Note, you must have the kedro-lsp installed and on your PATH

There are a number of plugins that will help setup lsp functionality in nvim, but if you want a bare minimum go-to-definition add this to your .vimrc as well.

nnoremap <leader>n <cmd>lua vim.lsp.buf.definition()<CR>

If you are having any issues with kedro-lsp not working in nvim try running :LspInfo or looking into your ~/.cache/nvim/lsp.log file.

Todos

• Provide diagnostic when there is a typo in dataset or parameter name in the pipeline.
• Be Kedro environment-aware
