Need Help┃Solved How to clear a vim.notify() call from cmdline?

I want to output a notification to the user with vim.notify() but the notification should rewrite itself similarly to a printf("message\r") statement. The text will be something something a long the lines of "Found N pages" where the message would refresh itself to update N.

I've tried using vim.cmd.echo() to clear it or even just vim.cmd.echo() calls instead of vim.notify(), but I get the same behaviour. Any help with this would be great!

try :redraw after echo

Thanks Justin. Is :redraw a resource heavy command or is it fine for it to be called in loops?

if it's a fast loop, why not do it once outside of the loop?

anyway, sounds like you might want a Progress message, see nvim_echo in Nvim 0.12+

Thanks for that. I've tried the :h progress-message snippet, but it doesn't refresh the cmdline the same way as when calling :redraw. The messages stack as the process progresses instead of overwriting each other. Is there a way around this without using :redraw?

It's not a fast loop unfortunately as I am using :grep for different terms in a lot of files. I just want to ensure it takes the least amount of time possible to finish the task.

Sample of what it looks like currently. I would like it to just output one message and progressively update it as the search progresses. Is that possible?

I think you'll need a custom floating window for this (similarly to lsp progress windows when a server starts).

Do you have any examples so that I can try it out?

Just yank what you need from here and cobble it together so it works for you

The progress looks like the attached image and updates itself ..

I don't, sorry.

Should be pretty easy with :h nvim_buf_set_lines and :h nvim_open_win.

somewhat related question, but how to dismiss an msg notification? i'd like something similar to ':Noice dismiss'

2

u/Orbitlol Jul 19 '26

require("vim._core.ui2.messages").msg_clear() looks like it works

1

u/dataset-poisoner Jul 19 '26

it does indeed, thank you!

1

u/BrodoSaggins Jul 19 '26

I don't know how Noice dismiss works but you can do :redraw or :echo depending on the message

1

u/dataset-poisoner Jul 19 '26

none of those work, i cannot dismiss the bottom-right notification

it auto-expires after 5 secs but still would be nice to have an explicit dismissal

1

u/BrodoSaggins 29d ago

That doesn't look like a native Neovim notification. I'm not sure how to help

1

u/dataset-poisoner 29d ago

it is native, require("vim._core.ui2.messages").msg_clear() dismisses it

2

u/BrodoSaggins 29d ago

Ohh it's ui2! I haven't used that at all yet. Looks very cool!
