From 22f1ce4a115795f2ef12f49e0013eece2b633122 Mon Sep 17 00:00:00 2001 From: Daniel Imms <2193314+Tyriar@users.noreply.github.com> Date: Tue, 19 Dec 2023 08:16:48 -0800 Subject: [PATCH] Add bg+powerline background blend behavior When a with bg is selected, the cell's regular background will be blended with 50% opacity selectionBackground in order to retain the bg color info as well as getting the color to change and getting decent contrast. This commit also fixes a terrible, nasty bug where the standalone shared renderer tests were causing the terminal to open multiple times and not get the WebGL addon activated the second time. So some tests were actually testing the DOM renderer :o Fixes #4918 --- .../renderer/dom/DomRendererRowFactory.ts | 4 +- .../renderer/shared/CellColorResolver.ts | 102 ++++++++++++++++-- src/browser/renderer/shared/RendererUtils.ts | 2 +- src/browser/renderer/shared/TextureAtlas.ts | 4 +- src/common/Color.test.ts | 21 ++++ src/common/Color.ts | 17 +++ test/playwright/Renderer.test.ts | 5 +- test/playwright/SharedRendererTests.ts | 93 +++++++++++----- 8 files changed, 208 insertions(+), 40 deletions(-) diff --git a/src/browser/renderer/dom/DomRendererRowFactory.ts b/src/browser/renderer/dom/DomRendererRowFactory.ts index 6ab68e7d6..50d3eb49e 100644 --- a/src/browser/renderer/dom/DomRendererRowFactory.ts +++ b/src/browser/renderer/dom/DomRendererRowFactory.ts @@ -11,7 +11,7 @@ import { ICoreService, IDecorationService, IOptionsService } from 'common/servic import { color, rgba } from 'common/Color';
