snippets.nvim VS ultisnips

Seems like vim-vsnip and snippets.nvim are popular to migrate into.

I'm moving from coc.nvim to built-in LSP and thereby considering changing from UltiSnips to some other snippet plugin, preferably one written in Lua. I've found two different ones: snippets.nvim and LuaSnip. Is there anyone with more experience with either of them that can say whether they are mature enough yet to be used. Or do you recommend some other snippet plugin written in VimL?

The documentation of snippets.nvim feels nonexisting (only 1 wiki example), so you might just adapt this quite extensive snippets.

I always like people's LaTeX-based note taking setups. I'm a mathematician, so I write a lot of LaTeX too. (And I use vim, so I really like vim+Latex workflows).

It's interesting that this post (or rather, the later post that discusses this) talks about the advantages of UltiSnips. The well-known vim-LaTeX posts written by Gilles Castel (RIP) relied pivotally on UltiSnips.

It's not just that UltiSnips is a snippet engine. There are many of those (including LuaSnip, the other snippet engine mentioned in the OP series of articles). It's that UltiSnips can dispatch arbitrary expressions to short python code sections, and python has a great scientific library. For example, it's trivial to write a `sympy` snippet that will simplify or compute a given expression and write the output in latex for you.

But UltiSnips works *terribly* with neovim [1] [2]. Why? Because UltiSnips uses python, and neovim's python interface is 100x slower than vim's python interface. There are design decisions for this and I'm not trying to say that neovim is bad. I use both vim and neovim. But I use vim+UltiSnips+vimtex for writing LaTeX.

LuaSnip has interpolation too. I suppose it would be possible to write more code that calls from LuaSnip to a system like sympy (or other). But that's work. On the other hand, I think it takes a true power user to actually want or use the fancy interpolation functions.

I think in-the-wild examples like Ultisnips deoplete semshi (although they are advanced and somewhat complex) would also be good examples to learn how one can use python for writing plugins.

I didn't know lsp-zero, but this integration seems just for me except for that I am using UltiSnips instead of luasnip. Just curious how difficult do you think it is to add UltiSnips integration along with cmp-nvim-ultisnips?

If you use UltiSnips, you can just do this:

The other option will be to use some snippets plugin to achieve same/similar functionality. One such option is ultisnips.

Snipets or code completion can be done in a number of different ways, and how that is configured will depend on what method you use. In the blog he uses the vim plugin ultisnips. You'll find details on configuration for that in that link.

Heyo, I've been trying to get UltiSnips and YouCompleteMe to work, however, I've ran into a bit of a problem. The python36.dll library does not seem to exist for UltiSnips, and YouCompleteMe cannot locate python at all (screenshots at bottom).

for actual use, I suspect most editors have a snippets plugin or such that is generally much more powerful and interactive/visual; for example see https://github.com/SirVer/ultisnips
