Editor

The language server protocol can be launched with vapour -lsp. Note that the LSP only runs on save (live diagnostics are obnoxious).

Integrations​

Vim​

Install the Vim integration to get syntax highlighting as well as LSP diagnostics.

Plug 'vapourlang/vapour-vim'

Neovim​

Install the Neovim integration to get syntax highlighting as well as LSP diagnostics.

{
  "vapourlang/vapour-nvim",
  config = function()
    require("vapour").setup()
  end
}

Vscode​

Install the extension to get syntax highlighting as well as LSP diagnostics.

Customise​

You can customise the LSP by creating a .vapour file in your home directory (~).

{
  "lsp": {
      "when": ["open", "save", "close", "change"],
      "severity": ["fatal", "warn", "hint, "info"]
    }
}

When​

Defines when the LSP runs:

• open: when a vapour file is opened
• save: when a vapour file is saved
• close: when a vapour file is closed
• change: when a vapour file is changed

You can remove any of these to disable that behaviour, e.g.: you can remove change to not have the LSP interrupt you as you write code.

Severity​

Customise what errors are displayed:

• fatal: fatal errors that result in the code not being transpiled to R
• warn: severe warnings that result in the code not being transpiled to R
• hint: hints to improve code
• info: informational messages

Remove a severity to not have messages of that severity shown in your editor (not recommended).
