This version introduces a new DDS (Data Distribution Service) aimed at facilitating communication and state synchronization between multiple Yazi instances, as well as state persistence.

It's built on a client/server architecture (without the need for running additional server processes), and deeply integrates with a Lua-based publish-subscribe model.

It also provides a set of new command-line options for interaction, such as ya pub, ya pub-static, yazi --local-events, yazi --remote-events, and currently used for:

• Cross-process yank-paste

• Change Yazi's CWD to PWD on subshell exit

  https://github.com/sxyazi/yazi/assets/17523360/fe571f77-1922-4d72-99f8-3a341c2c9046

• Integration with the new yazi.nvim plugin: subscribing to file deletion, movement, and renaming events through yazi --local-events to keep Neovim's buffer/LSP in sync

• bookmarks.yazi plugin: Saving bookmarks added by the user through the persistence feature provided by DDS

Performance optimizations

• Reduced CPU overhead during icon matching: Icon matching accounted for 35.6% of CPU time during rendering, and by changing the matching algorithm, this proportion has been reduced by ~10%
• Caching of each matched icon to avoid repeated calculations: By caching icons, further reductions in CPU usage for matching are achieved, as only a few new files that appear when scrolling through panes need to be matched
• Re-implemented the file watcher in an async way: This is the only sync I/O operation besides configuration initialization at startup, which occurs during cd and scrolling through the file list. For certain slow external devices, Yazi would experience noticeable lagginess, which has now been addressed, see https://github.com/sxyazi/yazi/pull/877 for more details

Feature enhancements

• Re-implemented fzf and zoxide as plugins for better flexibility: fzf and zoxide have added more runtime error handling. zoxide now supports the new update_db feature, which automatically adds Yazi's CWD to zoxide when navigating. To enable it, add the following to your init.lua:

  require("zoxide"):setup {
      update_db = true,
  }
  

• Maintain the original modification time when copying files
• Support smart case for cd path completion
• Add placeholder messages when there are no files in the directory
• Preserve the order of file selection when performing open, shell, or bulk rename on multiple selected files
• Prevent copying a directory to itself

The plugin system has also seen some improvements:

• ya.dbg() and ya.err() now support printing any type of data
• New ps API as a carrier for DDS interaction
• ya.manager_emit() now supports passing Url type
