Release Notes

xtermjs/xterm.js

### [`v4.19.0`](https://togithub.com/xtermjs/xterm.js/releases/tag/4.19.0) [Compare Source](https://togithub.com/xtermjs/xterm.js/compare/4.18.0...4.19.0) #### 🚀 Features - The minimum contrast ratio feature will now change luminance in the opposite direction if the contrast ratio isn't met ([#​3806](https://togithub.com/xtermjs/xterm.js/issues/3806), [#​3808](https://togithub.com/xtermjs/xterm.js/issues/3808)) via [@​Tyriar](https://togithub.com/Tyriar). For example a red foreground on a slightly darker red background will try lighten the color and if the `minimumContrastRatio` option isn't met when `#FFFFFF` is reached it will try moving it towards `#000000`. This can cause somewhat unexpected results by changing explicitly styled whites to blacks for example but it's really good for accessibility. - The library now supports parsing `#rgb`, `#rgba`, `rgb(r, g, b)` and `rgba(r, g, b, a)` color formats ([#​3815](https://togithub.com/xtermjs/xterm.js/issues/3815), [#​3819](https://togithub.com/xtermjs/xterm.js/issues/3819), [#​3823](https://togithub.com/xtermjs/xterm.js/issues/3823)) via [@​ChaseKnowlden](https://togithub.com/ChaseKnowlden), [@​Tyriar](https://togithub.com/Tyriar) - Opaque `selectionBackground` is now supported in the DOM renderer ([#​3839](https://togithub.com/xtermjs/xterm.js/issues/3839)) via [@​Tyriar](https://togithub.com/Tyriar) - The symbol powerline font glyphs now use custom rendering when `ITerminalOptions.customGlyphs` is enabled ([#​3856](https://togithub.com/xtermjs/xterm.js/issues/3856), [#​3862](https://togithub.com/xtermjs/xterm.js/issues/3862), [#​3866](https://togithub.com/xtermjs/xterm.js/issues/3866)) via [@​Tyriar](https://togithub.com/Tyriar)  This has multiple benefits: - A patched powerlines font doesn't need to be installed to render the most common characters - Ugly lines due to anti-aliasing that can appear no longer do - The glyphs always use greyscale anti-aliasing (not sub-pixel) - `ITerminalOptions.lineHeight` is taken into account when rendering the glyph ##### 📦 API - The overview ruler is a companion feature to the decorations introduced in 4.18.0 which shows little indicators on the scroll bar ([#​3676](https://togithub.com/xtermjs/xterm.js/issues/3676), [#​3687](https://togithub.com/xtermjs/xterm.js/issues/3687), [#​3688](https://togithub.com/xtermjs/xterm.js/issues/3688), [#​3689](https://togithub.com/xtermjs/xterm.js/issues/3689), [#​3693](https://togithub.com/xtermjs/xterm.js/issues/3693), [#​3694](https://togithub.com/xtermjs/xterm.js/issues/3694), [#​3695](https://togithub.com/xtermjs/xterm.js/issues/3695), [#​3697](https://togithub.com/xtermjs/xterm.js/issues/3697), [#​3702](https://togithub.com/xtermjs/xterm.js/issues/3702), [#​3711](https://togithub.com/xtermjs/xterm.js/issues/3711), [#​3723](https://togithub.com/xtermjs/xterm.js/issues/3723), [#​3730](https://togithub.com/xtermjs/xterm.js/issues/3730), [#​3733](https://togithub.com/xtermjs/xterm.js/issues/3733), [#​3738](https://togithub.com/xtermjs/xterm.js/issues/3738), [#​3788](https://togithub.com/xtermjs/xterm.js/issues/3788), [#​3791](https://togithub.com/xtermjs/xterm.js/issues/3791), [#​3792](https://togithub.com/xtermjs/xterm.js/issues/3792), [#​3841](https://togithub.com/xtermjs/xterm.js/issues/3841)) via [@​meganrogge](https://togithub.com/meganrogge), [@​Tyriar](https://togithub.com/Tyriar). To use it, add the `overviewRulerOptions` property to a decoration's `IDecorationOptions` and it will automatically show up in the overview ruler. ```ts const marker = term.addMarker(1); const decoration = term.registerDecoration({ marker, x: 5, overviewRulerOptions: { color: '#FF0000', position: 'left' } }); decoration.onRender(() => { decoration.element.style.backgroundColor = 'red'; }); ``` The width of the resulting overview ruler is controlled by `ITerminalOptions.overviewRulerWidth`. - Decorations can now change a cell's background and foreground colors ([#​3775](https://togithub.com/xtermjs/xterm.js/issues/3775), [#​3782](https://togithub.com/xtermjs/xterm.js/issues/3782)) via [@​Tyriar](https://togithub.com/Tyriar). When this is set, the minimum contrast ratio feature will also be in effect. ```ts const decoration = term.registerDecoration({ marker, backgroundColor: '#ff0000', foregroundColor: '#ffffff' }); ``` - Decorations can now specify the layer property to allow rendering above the selection ([#​3785](https://togithub.com/xtermjs/xterm.js/issues/3785), [#​3800](https://togithub.com/xtermjs/xterm.js/issues/3800)) via [@​Tyriar](https://togithub.com/Tyriar) ```ts const decoration = term.registerDecoration({ marker, layer: 'top' }); ``` - There's a new `selectionForeground` theme color, when set this will use a static color for selections ([#​3813](https://togithub.com/xtermjs/xterm.js/issues/3813)) via [@​Tyriar](https://togithub.com/Tyriar) ```ts const term = new Terminal({ theme: { selectionBackground: '#​000000', selectionForeground: '#FFFFFF' } }); ``` #### 🐞 Bug fixes - Fix triple click selection edge case where initial line was getting unselected ([#​3669](https://togithub.com/xtermjs/xterm.js/issues/3669)) via [@​silamon](https://togithub.com/silamon) - Fixing edge cases when clearing decorations via `Terminal.clear` ([#​3671](https://togithub.com/xtermjs/xterm.js/issues/3671), [#​3868](https://togithub.com/xtermjs/xterm.js/issues/3868)) via [@​meganrogge](https://togithub.com/meganrogge) -

Exclude powerline characters from the minimum contrast ratio feature ([#​3740](https://togithub.com/xtermjs/xterm.js/issues/3740), [#​3742](https://togithub.com/xtermjs/xterm.js/issues/3742)) via [@​meganrogge](https://togithub.com/meganrogge) -
