paste from system clipboard not working under linux (Ubuntu)

[umazanatastatura]

Hi,

I'm using helix 22.12 (96ff64a) on
5.19.0-26-generic Ubuntu 22.10

and hx --health | head shows:
Clipboard provider: termcode
System clipboard provider: termcode

Terminal: GNOME Terminal Version 3.46.2 for GNOME 43
Using VTE version 0.70.0 +BIDI +GNUTLS +ICU +SYSTEMD

Issue: Nothing happens when I paste text from system clipboard.
Observation: I've tried to use fish shell and pasting under it works, so I assume it's because of "system clipboard provider"..

The termcode provider can't paste any values you didn't yank with <space>y/<space>Y within helix:

helix/helix-view/src/clipboard.rs

Lines 223 to 247 in 0c51201

	fn get_contents(&self, clipboard_type: ClipboardType) -> Result<String> {
	// This is the same noop if term is enabled or not.
	// We don't use the get side of OSC 52 as it isn't often enabled, it's a security hole,
	// and it would require this to be async to listen for the response
	let value = match clipboard_type {
	ClipboardType::Clipboard => self.buf.clone(),
	ClipboardType::Selection => self.primary_buf.clone(),
	};
	Ok(value)
	}
	fn set_contents(&mut self, content: String, clipboard_type: ClipboardType) -> Result<()> {
	#[cfg(feature = "term")]
	crossterm::execute!(
	std::io::stdout(),
	osc52::SetClipboardCommand::new(&content, clipboard_type)
	)?;
	// Set our internal variables to use in get_content regardless of using OSC 52
	match clipboard_type {
	ClipboardType::Clipboard => self.buf = content,
	ClipboardType::Selection => self.primary_buf = content,
	}
	Ok(())
	}

You should install a clipboard provider program (see the Wiki link kirawi posted) for paste to work as you expect. For Wayland this would be wl-clipboard.
