From 38149872989477f62222ce68dc32d2d6018ae165 Mon Sep 17 00:00:00 2001 From: Michael Davis Date: Fri, 4 Nov 2022 11:04:16 -0500 Subject: Fix panic on paste from blackhole register (#4497) The sequence "_y"_p panics because the blackhole register contains an empty values vec. This causes a panic when pasting since it unwraps a `slice::last`.--- helix-term/src/commands.rs | 5 +++++ 1 file changed, 5 insertions(+) (limited to 'helix-term/src') diff --git a/helix-term/src/commands.rs b/helix-term/src/commands.rs index a6ee6263..ef963477 100644 --- a/helix-term/src/commands.rs +++ b/helix-term/src/commands.rs @@ -3447,7 +3447,12 @@ enum Paste { } fn paste_impl(values: &[String], doc: &mut Document, view: &mut View, action: Paste, count: usize) { + if values.is_empty() { + return; + } + let repeat = std::iter::repeat( + // `values` is asserted to have at least one entry above. values .last() .map(|value| Tendril::from(value.repeat(count))) -- cgit v1.2.3-70-g09d2
