ultisnips VS vim-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:

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).

Also, I'm using vim-snipmate style snippets in LuaSnip. How can I import snippets in javascript.snippets in html.snippetswithout having to copy everything.

cmp works fine and I was able to trivially make it only suggest lsp completion for me by only including lsp sources. The setup is significantly more complicated with having the install 7ish plugins instead of just 3 for coq. I don't think I would've had the patient to go through the setup when I was just starting to use neovim. cmp also have much nicer UI (e.g. it shoulds documentation and sometimes function signiture as you browse through the suggestion.) With snippet you can find something like https://github.com/honza/vim-snippets which have more than what I need. You also need to choose a snippet engine so that's more decision to make.

Since LuaSnip also supports snipmate I'm using vim-snippets since it's offering a lot of snippets I'm using often without having to write my own. But as @eliizaak said: it's not Lua and perhaps I'll find the time and energy to learn a bit more about LuaSnip and write my own snippets ... ;)

It includes the snippets from honza/vim-snippets and my own snippets.

vim-snippets as you've already mentioned.

Skimming over the blog post you linked, it appears that the author uses Vim plugins to get some of the snippets working, which I'm near-certain is impossible with the Vim features available to Obsidian. I don't think installing Vim plugins with vim-plug (as used by both myself and the author of the linked blog) is possible in Obsidian, for example. Without some way to manage installing Vim plugins, you won't be able to get plugins which enable vim snippets as used in the blog post.

Sorry does it?

Auto adding include files or a specific non-static function is generally a bad idea, but I use yasnippet on Emacs for copyright/licensing info, this seemingly has the same purpose but oriented towards vim users, which makes file templates trivial (on Emacs at least, I don’t usually use vim unless I can’t use Emacs or mg for some reason).
