Difference between nvim-surround and vim-surround

[perseoGI]

Hi!
What are the main differences between this plugin and the old school vim-surround (apart from being written in lua)?

Hi there! Here's a list of a few things that stand out to me (hopefully others will add to this list if I forget anything):

• Inserting function-evaluated surrounds
  • This allows for processing to be done while the surround is being created, e.g. getting user input, calling into Tree-sitter, etc.
  • Some examples of this can be found in the showcase page
• When changing/deleting, jumping can occur backwards if no surrounding pairs are found around the cursor nor after, so if the cursor is in the comment for the below example, then ds" will delete the quotes anyhow

local str = "some text" -- with a comment

• Character "aliasing" allows you to let one char stand in for several other characters, e.g. by default q is mapped to { `, ', " }. That way dsq will delete the nearest set of quotes of any kind, which ties in with dot-repeating quite nicely I think. See the README's video for an example.
• Highlighting inserts/changes can be seen in the README's demo video, which can be nice for checking yourself

This is pretty neat! I have already uninstalled old tpope's and installed yours.
Love each of the points you answer!
Great job 🚀

Is there anything this plugin does not have but tpope/vim-surround has? Also this should be faster because its written in LUA right?

Hi there, so far I think I've covered most (if not all) of what tpope's vim-surround has (at the very least I haven't gotten a feature parity request in a while). I will say that speed shouldn't really be a deciding factor, as the actual computations performed in both aren't very intensive. If you're curious, I would recommend trying out nvim-surround as a drop-in replacement and see how it works for yourself. The main two benefits would be more functionality (e.g. dsf for deleting function calls), as well as a saner configuration language. If you have any more questions, feel free to ask!
