julia-vim VS vim-vsnip

There's a handy Vim plug-in for Julia that will convert latex commands to symbols so it's a one character difference for a pretty notable improvement to readability when you start to get into longer equations.

Nowadays during my master thesis does lots of equations appear in my python code, but I would love to use tex rendering in some way, like latex preview in emacs. However, I know that there is some great latex rendering such as tex-conceal.vim and latex_to_unicode in julia-vim, but I am not able to make it work for python comments. Any idea on how to solve this?

There is a plugin I tried which is called julia-vim. However, this plugin is too broken for me. It conflicts with other completion plugins which makes it so hard to either fix or manage my configuration and keymaps. Fortunately, I found cmp-latex-symbols, a completion plugin that as described in the README

I use Git and plain text files. The Julia addon for Vim allows one to write UTF-8 math symbols with LaTeX commands.

I use julia.vim for unicode support. I find it a bit more responsive than agda-vim, and it has more symbols (the list is autogenerated). but I have two gripes with it:

Ideally, yes, I want to use LSP in order for it to work as close as possible from my nvim with julia-vim, coc.nvim and vim-julia-cell. At least until I'm more familiarized with Emacs. I really do want to learn, but I cannot just stop my daily work, so the best world possible would be to be able to keep working while learning.

I use vim+vim_slime along with the julia plugin configured with tab latex to unicode conversion. This means I can have a REPL open in a split vim buffer and send chunks from my script directly to the REPL. It's really lightweight and fast. I'm working to make some functional snippets too.

Since I was still missing some more advanced Vim features, I did some search and now have a pretty decent terminal based environment. The base is Tmux + Neovim- I open 2 panes, where one is used for coding and the other is Julia REPL. I use julia-vim plugin for base syntax and code highlights and vim-slime with vim-julia-cell for live sending of the code from the Neovim to the REPL.

My go to these days has been https://github.com/hrsh7th/vim-vsnip. It is compatible with LSP and VSCode snippet format. Since it is in pure VimScript you don’t need to battle configuring python just to get the plug-in to work.

I first started by reading some tutorials but most of those used parser combinators. For me, parser combinators always caused some issues sooner or later (at least in Lua when trying to parse recursive / nested nodes). An example project that uses this technique is vim-vsnip: https://github.com/hrsh7th/vim-vsnip/blob/master/autoload/vsnip/snippet/parser.vim. Later, I found out that Luacheck uses a different approach which I liked better: https://github.com/lunarmodules/luacheck/blob/master/src/luacheck/parser.lua. That's the project that helped me the most while writing my own parsers for different snippet engines.

This plugin could use it? hrsh7th/vim-vsnip

I am not a snippets expert, I don't even currently use snippets. However, I know that both LuaSnip and vim-vsnip can load these vscode style snippets. So my recommendation would be to get the snippets and use one of those two snippet plugins.

For autocompletion I use the nvim-cmp plugin. If you're not coding, it might be overkill. But during writing it helps me a lot, because it autosuggests words that I used in the current buffer, too. The most popular autocomplete plugins should be compatible with the most popular snippets engines like vim-vsnip.

Have you ever wondered how to have a snippet completion in VSCode so you can write Julia code fast but in Neovim? Fear not! vim-vsnip is the plugin you need. This plugin supports LSP/VSCode's snippet format. But first, you need to install cmp-vsnip for this plugin to be sourced to nvim-cmp. Oh btw, these three plugins: nvim-cmp, vim-vsnip, and cmp-vsnip → are made by the same person which is actually cool! If you want to support them, become a sponsor! (I am poor so I cannot sponsor yet 😔)

I believe you want the second variant. Then you should install some snippet plugin like vsnip or luasnip and config it with your completion engine.

https://github.com/hrsh7th/vim-vsnip says it supports vscode style snippets, so apparently you could use https://marketplace.visualstudio.com/items?itemName=kaffeine.advanced-drupal-8-snippets with that plugin.
