xterm.js - 5.4.0

Published by Tyriar 8 months ago

📢 The package has been migrated to the @xterm scope (#4860, #4861) via @Tyriar. This means that the old xterm and xterm-* packages are now deprecated and will no longer be maintained. This was done mainly for security reasons to remove ambiguity around the package names and to prevent potential typosquatting attacks.

Please use the new scoped @xterm/* packages.

    }
});

xterm.js - 5.1.0

Published by Tyriar almost 2 years ago

🚀 Features

Multiple texture atlas page support (#4244, #4252, #4274) via @Tyriar

Instead of there being a hard cap of 1024x1024 on the size of the texture atlas backing the canvas and webgl renderers, multiple textures are now supported. Each individual texture is now 512x512 which allows faster uploading to the GPU and will continually merge until the maximum of 4096x4096 is reached.

The benefits in simple terms of this change are:

Less time from drawing a glyph to rendering it
Less CPU is used when lots of glyphs are used
Essentially unlimited space for glyphs, which is good for certain use cases but will also let us explore things like "perfect" dotted and curvy underlines in the future

Here is an example of a 512x512 texture atlas page right after the terminal has loaded and printed a powerline-based prompt:

And here is the 1024x1024 page after a lot of glyphs have rendered:

Slash and triangle custom glyphs (#4313) via @Tyriar

Eight new powerline extra custom glyphs are supported:

New option scrollOnUserInput (#4289) via @JasonXJ

You can now specify whether to scroll to the bottom of the terminal on user input, previously this was the default and only behavior. This new setting is enabled by default.

const term = new Terminal({ scrollOnUserInput: false });

🛑 Breaking changes

There is a new allowNonHttpProtocols property on ILinkHandler which forces the embedder to opt-in to non-http(s) protocols. This is a breaking change in a minor release as it could improve security of embedders.

// before 5.1.0
const term = new Terminal({
  linkHandler: {
    ...
  }
};

// after 5.1.0
const term = new Terminal({
  linkHandler: {
    // If you explicitly support and sanitize the links
    allowNonHttpProtocols: true,
    ...
  }
};

xterm.js - 5.0.0

Published by Tyriar about 2 years ago

v5 is here! This is our largest release in a long time, maybe ever 👀

Since this was a major version bump, we used the opportunity to clean up the API and make other breaking changes. Many of these changes enabled a significant reduction in the xterm module bundle size which went from 379kb to 265kb for a 30% reduction!

Some work was also done to improve underline rendering overall, characters with long descenders don't overlap with the underline:

Hyperlink escape sequence support (#4005, #4087, #4088) via @Tyriar, @jerch

Building upon the improved underline rendering, hyperlink escapes outlined in this gist are now supported. They will be rendered using a dashed underline (like CSI 4:5m ST):

Along with this is a new linkHandler option which allows controling hover, leave and activate events, for example to show a custom tooltip. VS Code's implementation looks like this:

Smooth scroll support (#3940) via @Tyriar

The new smoothScrollDuration allows setting a duration in milliseconds to animate scroll between the origin and target positions. This is most useful when using a physical mouse (not a trackpad) to help not disorient the user when scrolling with the mouse wheel.

Canvas renderer addon (#3949, #3950, #3954, #3959, #3961, #3981) via @Tyriar

The canvas renderer has moved into an addon, significantly reducing the bundle size of the xterm module. This used to be the default renderer and is now recommended only as a fallback to the webgl addon if that does not work for some reason (eg. no webgl2 support).

New VT feature support (#4093, #4095, #4098)via @jerch

🛑 Breaking changes

bellSound and bellStyle options as well as the previously builtin sound have been removed (#3941) via @Tyriar. This reduces the bundle size while still allowing the embedder to support the terminal bell via the Terminal.onBell API
```
// before 5.0.0
term = new Terminal({
  bellStyle: 'sound'
});

// after 5.0.0
term = new Terminal();
term.onBell(() => {
  // Play a sound
});
```
The link matcher API registerLinkMatcher and deregisterLinkMatcher have been removed in favor of the link provider API (#3944) via @Tyriar.

The allowProposedApi option now defaults to false, set this to true to opt-in to proposed API usage if you understand the implications (#3945) via @Tyriar

// before 5.0.0
term = new Terminal({});
term.someProposedApi();

// after 5.0.0
term = new Terminal({
  allowProposedApi: true
});
term.someProposedApi();

The deprecated addMarker API has been removed in favor of registerMarker (#3946) via @Tyriar. They are functionally equivalent.

The deprecated getOption and setOption APIs have been removed in favor of options (#3947) via @Tyriar

// before 5.0.0
term.setOption('scrollback', 1000);
console.log(term.getOption('scrollback'));

// after 5.0.0
term.options.scrollback = 1000;
console.log(term.options.scrollback);

The deprecated writeUtf8 API has been removed in favor of write (#3947) via @Tyriar.

const arr = new Uint8Array(10);

// before 5.0.0
term.writeUtf8(arr);

// after 5.0.0
term.write(arr);

ISelectionPosition have been removed from the API in favor of IBufferRange (#3952) via @Tyriar
cols and rows options can now only be set in the constructor (#3960, #3972, #4078) via @Tyriar, @silamon
```
// before 5.0.0
term.setOption('cols', 10);

// after 5.0.0
term.resize(10, term.rows);
```

ITheme.selection has been renamed to selectionBackground for consistency (#3964) via @Tyriar

// before 5.0.0
term.options.theme = { selection: '#000000' };

// after 5.0.0
term.options.theme = { selectionBackground: '#000000' };

The Terminal.options getter now returns a Required<ITerminalOptions> instead of just ITerminalOptions for better correctness. Along with this change fastScrollModifier now accepts 'none' instead of undefined
```
// before 5.0.0
new Terminal({ fastScrollModifier: undefined });

// after 5.0.0
new Terminal({ fastScrollModifier: 'none' });
```

xterm-addon-webgl

More efficient GPU memory usage using new texture atlas packing strategy (#3979) via @Tyriar

The previous naive texture packing strategy which only allowed adding to the "active row" or below has been replaced with a new strategy that uses multiple active rows and adds glyphs to the most suitable row based on its pixel height. This leads to more effective usage of the texture xterm.js uploads to the GPU, meaning it's harder to reset the texture when it becomes filled (which is more likely to happen when screen scale is high).

🚀 Features

The minimum contrast ratio feature will now change luminance in the opposite direction if the contrast ratio isn't met (#3806, #3808) via @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, #3819, #3823) via @ChaseKnowlden, @Tyriar
Opaque selectionBackground is now supported in the DOM renderer (#3839) via @Tyriar
The symbol powerline font glyphs now use custom rendering when ITerminalOptions.customGlyphs is enabled (#3856, #3862, #3866) via @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, #3687, #3688, #3689, #3693, #3694, #3695, #3697, #3702, #3711, #3723, #3730, #3733, #3738, #3788, #3791, #3792, #3841) via @meganrogge, @Tyriar. To use it, add the overviewRulerOptions property to a decoration's IDecorationOptions and it will automatically show up in the overview ruler.
```
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, #3782) via @Tyriar. When this is set, the minimum contrast ratio feature will also be in effect.
```
const decoration = term.registerDecoration({
  marker,
  backgroundColor: '#ff0000',
  foregroundColor: '#ffffff'
});
```
Decorations can now specify the layer property to allow rendering above the selection (#3785, #3800) via @Tyriar
```
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) via @Tyriar

const term = new Terminal({
  theme: {
    selectionBackground: '#000000',
    selectionForeground: '#FFFFFF'
  }
});

xterm.js - 4.12.0

Published by Tyriar over 3 years ago

🚀 Features

Double click to select a word will now use link providers registered via the API (#3230) via @marvinthepa
Support the ligatures addon with the DOM renderer (#3285) and WebGL renderer (#3286) via @Tyriar

📦 API

Support async parser handlers (#3222, #3256, #3257, #3267) via @jerch. This enables for example custom parser handlers to defer heavy work to a worker thread. Note that this will block the terminal and you should generally stay away from this API unless it's a lot of work that would block the UI thread.
```
// Handle \x1b[<params>+Z using an asynchronous handler
terminal.parser.registerCsiHandler({intermediates:'+', final: 'Z'}, async params => {
  await new Promise(res => setTimeout(res, 50));
  return false;
});
```
Add onBell event API so embedders can handle the bell however they want (#3290, #3295) via @bmf-ribeiro
```
terminal.onBell(() => customBellImpl());
```

xterm.js - 4.9.0

Published by Tyriar about 4 years ago

📦 API

Add number support to fontWeight and fontWeightBold options (#3062) via @IllusionMH, this now matches the types that the CSS style supports.
Support optional dispose function on ILink (#3073) via @Tyriar, this allows consumers to be notified when links are no longer needed which was difficult to observe before.

🐞 Bug fixes

Fix renderer pausing when Terminal.open is called during an animation (#3008) via @andrew-schlackman
Use document role instead of list for the terminal (#3020) via @Tyriar
Constructor options are now validated just like when using setOption (#3064) via @IllusionMH
Fix rendering of multi-line selection when only top row is visible (#3081) via @Tyriar
Fix first/last line of selection sometimes not rendering with the canvas renderer (#3082) via @Tyriar

📝 Documentation and internal improvements

Remove the no longer supported Dockerfile from the repo (#3026) via @Tyriar
Update to TypeScript 4 (#3059) via @Tyriar

🛑 Breaking changes

getOption('fontWeight') and getOption('fontWeightBold') now returns string | number instead of string:
```
// before 4.9.0
const weight: string = term.getOption('fontWeight');

// after 4.9.0
const weight: string | number = term.getOption('fontWeight');
```
This change accepted as the impact on consumers should be minimal due to the low usage of the API.
