Relative line numbers

[gbaranski]

Describe your feature request

Vim-like relative line numbers, they're very helpful for code navigation.

this could be configured like that

line_numbers = "none" # No line numbers
line_numbers = "absolute" # Absolute line numbers(default)
line_numbers = "relative" # Relative line numbers

[gbaranski]

I can try implementing that after I'll finish #478

How will this work with multiple cursors?

[pickfire]

There will still be one main cursor with multi cursors.

helix/helix-term/src/ui/editor.rs

Lines 330 to 355 in eba0bbd

	for (i, line) in (view.first_line..last_line).enumerate() {
	use helix_core::diagnostic::Severity;
	if let Some(diagnostic) = doc.diagnostics().iter().find(|d| d.line == line) {
	surface.set_stringn(
	viewport.x - OFFSET,
	viewport.y + i as u16,
	"●",
	1,
	match diagnostic.severity {
	Some(Severity::Error) => error,
	Some(Severity::Warning) | None => warning,
	Some(Severity::Info) => info,
	Some(Severity::Hint) => hint,
	},
	);
	}
	// line numbers having selections are rendered differently
	surface.set_stringn(
	viewport.x + 1 - OFFSET,
	viewport.y + i as u16,
	format!("{:>5}", line + 1),
	5,
	linenr,
	);
	}

This is where the line numbering is done.

I hope this can be toggled while editing. In Kakoune, it is possible to make pressing 0 temporarily toggle relative line numbers until the next command executes, which is very cool.

Hello. I didn't want to open a new issue, so I'll report here.
I think the relative numbers option is not working in the ~/.config/helix/config.toml file. But this is not working:

[editor]
line-number = "relative"

Nor line_numbers = "relative".

I'm new to Helix so maybe I'm configuring it the wrong way. Thank you

@tryzniak Relative line numbers are only in master and not yet released, so you'll have to build from source.

@sudormrfbin Thanks, I didn't notice that 😄

Any word on this becoming something you can switch to temporarily from within helix? I'd find that very useful!
