LuaSnip-Markdown-Snippets

A set of preconfigured snippets for latex math inside of markdown for the snippet engine LuaSnip.

Idea

These are snippets for Latex inside of markdown. My use case for this is math inside of Obsidian while writing in Neovim. This is a fork of evesdroppers luasnip-latex-snippets.

Installation

Lazy.nvim

{
  "LukasKorotaj/luasnip-markdown-snippets.nvim",
  dependencies = { "L3MON4D3/LuaSnip" },
  config = true, -- or custom configuration
}

Add these lines to ~/.config/nvim/queries/markdown_inline/highlights.scm:

;;; LaTeX-related captures
(latex_block) @latex_block
(latex_span_delimiter) @latex_delimiter

This is so that snippets are only active and usable inside of math blocks in markdown.

Enable autosnippets in your init.lua file:

config = function()
    local luasnip = require 'luasnip'

    luasnip.setup {
	enable_autosnippets = true,
    }
end,

If you are using kickstart.nvim don't forget to have only one luasnip.setup. The second one is hidden in cmp_luasnip.

Full Config Example

return {
  "LukasKorotaj/luasnip-markdown-snippets.nvim",
  config = function()
    local ls = require("luasnip")
    local t = ls.text_node
    local i = ls.insert_node
    local fmta = require("luasnip.extras.fmt").fmta
    local autosnippet = ls.extend_decorator.apply(ls.snippet, { snippetType = "autosnippet" })
    local lms = require 'luasnip-markdown-snippets'


    require("luasnip-markdown-snippets").setup({
      snippets = {
        markdown = {
          -- Override existing snippet
          autosnippet(
            { trig = "cb", wordTrig = false },
            { t("^4") }, -- original was ^3
            { condition = lms.in_math }
          ),
          
          -- New test snippet
          ls.snippet(
            { trig = "test", name = "testing snippets", dscr = "Test to check if new snippets work" },
            fmta([[
		testing <>, it is <>.
            ]], { i(1), i(0) })
          )
        }
      }
    })
  end
}

Additionally, I would like to thank Max Mehta for bringing up the idea of creating this plugin and the creator of LuaSnip, L3MON4D3, for helping me debug some of the early stages of the plugin. There are also functions scattered throughout the code which are not made by me, so I've posted acknowledgements for those in the comments of the code.
