Problem:
Nvim does not have a core concept for indicating "progress" of
long-running tasks. The LspProgress event is specific to LSP.
Solution:
- `nvim_echo` can emit `kind="progress"` messages.
- Emits a `Progress` event.
- Includes new fields (id, status, percent) in the `msg_show` ui-event.
- The UI is expected to overwrite any message having the same id.
- Messages have a globally unique ID.
- `nvim_echo` returns the message ID.
- `nvim_echo(… {id=…})` updates existing messages.
Example:
local grp = vim.api.nvim_create_augroup("Msg", {clear = true})
vim.api.nvim_create_autocmd('Progress', {
pattern={"term"},
group = grp,
callback = function(ev)
print(string.format('event fired: %s', vim.inspect(ev))..'\n')
end
})
-- require('vim._extui').enable({enable=true, msg={target='msg', timeout=1000}})
vim.api.nvim_echo({{'searching'}}, true, {kind='progress', percent=80, status='running', title="terminal(ripgrep)"})
local id = vim.api.nvim_echo({{'searching'}}, true, {kind='progress', status='running', percent=10, title="terminal(ripgrep)"})
vim.api.nvim_echo({}, true, {id = id, kind='progress', percent=20, status = 'running', title='find tests'})
vim.api.nvim_echo({}, true, {id = id, kind='progress', status='running', percent=70})
vim.api.nvim_echo({{'complete'}}, true, {id = id, kind='progress', status='success', percent=100, title="find tests"})
Followups:
- Integrate with 'statusline' by listening to the Progress autocmd event.
- Integrate progress ui-event with `vim._extui`.
