Pull request overview
This PR updates the @xterm/xterm library and its related addons from beta.77 to beta.89, addressing issue #239541. The update includes a significant dependency change in the addon-ligatures package, which now uses lru-cache and opentype.js directly instead of the intermediary font-finder and font-ligatures packages.
Key Changes
- Updates @xterm/xterm core library from beta.77 to beta.89
- Updates most xterm addons to beta.89 (clipboard, image, ligatures, progress, search, serialize, unicode11)
- Updates @xterm/addon-webgl to beta.88 (note: different from other addons)
- Simplifies addon-ligatures dependency tree by removing font-finder, font-ligatures, get-system-fonts, and promise-stream-reader
