From d8d6ec7d7a1033178cb7dd7fc95e9fad0cd571a4 Mon Sep 17 00:00:00 2001 From: DevLeonardoK Date: Tue, 14 Jul 2026 21:21:26 -0300 Subject: [PATCH] Add keybinding to cycle log tail line count in Logs tab Lets you press 't' while focused on the containers panel to cycle through common --tail presets (all, 50, 100, 200, 500) for the selected container's Logs tab, instead of only being able to set a fixed value via the logs.tail config option. The current value is shown in the Logs tab subtitle. --- docs/keybindings/Keybindings_de.md | 1 + docs/keybindings/Keybindings_en.md | 1 + docs/keybindings/Keybindings_es.md | 1 + docs/keybindings/Keybindings_fr.md | 1 + docs/keybindings/Keybindings_nl.md | 1 + docs/keybindings/Keybindings_pl.md | 1 + docs/keybindings/Keybindings_pt.md | 1 + docs/keybindings/Keybindings_tr.md | 1 + docs/keybindings/Keybindings_zh.md | 1 + pkg/gui/container_logs.go | 32 +++++++++++++++++++++++++++++- pkg/gui/containers_panel.go | 2 +- pkg/gui/gui.go | 7 +++++++ pkg/gui/keybindings.go | 7 +++++++ pkg/i18n/english.go | 2 ++ 14 files changed, 57 insertions(+), 2 deletions(-) diff --git a/docs/keybindings/Keybindings_de.md b/docs/keybindings/Keybindings_de.md index dc9dd08e..b3a2642c 100644 --- a/docs/keybindings/Keybindings_de.md +++ b/docs/keybindings/Keybindings_de.md @@ -25,6 +25,7 @@ _This file is auto-generated.
