Module: Rvim::Lua::Ui

Defined in:
lib/rvim/lua/ui.rb

Overview

vim.ui.input / vim.ui.select — modal input prompts.

NeoVim’s default implementations block on user input via vim.fn.input() / inputlist(). Without integrating into the editor’s interactive loop we can’t do that here, so v3.10 ships:

- synchronous fallbacks that call the callback with the default value
  (or nil) immediately. This matches NeoVim's "no UI provider" path.
- vim.ui.input / vim.ui.select are *replaceable* — plugins like
  dressing.nvim re-assign these tables, and that override mechanism
  works the same way here.

Tests cover the default fallback path AND the override path.
