What is the difference between this and vim-surround or vim-sandwich?

[ok-nick]

Hi, I am interested in switching to this plugin, but what advantages and disadvantages does it have over its predecessors? Obviously, for one, it's written in Lua, making it a much better configuration experience. What else?

Perhaps a table should be included in the README comparing them all to give potential users more of an incentive to migrate.

Hi there! There is this wiki page that I was originally planning on using for migration, but it is kind of out-of-date. I've mostly been focusing on patching bugs and trying to push out new features as soon as possible before I get busy with schoolwork again. I personally haven't really used vim-sandwich much, but from the little experience I do have, nvim-surround covers most of the common functionality, e.g. add/modify surrounds, but does not yet include the "sandwich" surrounds (see #135). This project mostly aims to be more or less a superset of everything vim-surround does, with a few minor tweaks that I find to be "more sensible". Most notably, < adds a < , > pair to the buffer instead of adding an HTML-style tag (which is done via t or T). As for bonus features, here we go:

• Dot-repeat support out-of-the-box
• Pattern-based surrounds, e.g. function calls can be deleted/changed via dsf/csf
  • Tree-sitter based surrounds are coming soon:tm:, in branch v2.0.0; they should give "more accurate" surrounds than pattern-based ones
• Surround aliasing, e.g. by default you can use dsq to delete the closest pair of `, ', and "
• Highlights for visual feedback on surrounds

In general I've tried to open this plugin up to be as extensible as possible, instead of hard-coding specific cases. For example, the HTML tags and function calls are actually not a part of the core plugin itself, but rather just part of the default user configuration that I've provided. You can see #53 to see some things that myself and others have created, to help with workflows.

TL;DR Pattern-based surrounds allow for modifying function calls, e.g. dsf, dot-repeat works out-of-the-box, and the extensibility of the plugin using Lua is unmatched by its VimL counterparts.

But yeah I definitely agree that I'm not really incentivizing people to switch at the moment; so far it's mostly just been people trying it out and liking the stuff that I've put in :) Hopefully in the future once I've "settled down" on adding new features/bug fixes, I can write some better docs on why this is a good alternative to older surround plugins.

BTW @ok-nick if you're looking at other surround plugins, mini.surround is also a notable alternative that I would recommend.
