See\n and\n.\n\n## Installation\n\nDepends on [vimtex](https://github.com/lervag/vimtex) to determine if the\ncursor is within math mode. Alternatively, you can use\n[nvim-treesitter](https://github.com/nvim-treesitter/nvim-treesitter) (experimental) by passing `{ use_treesitter = true }` to the setup call.\n\nIt's necessary to enable `autosnippets` in luasnip: `require(\"luasnip\").config.setup { enable_autosnippets = true }`.\n\nCan be installed like any neovim plugin. If using\n[wbthomason/packer.nvim](https://github.com/wbthomason/packer.nvim):\n\n```lua\nuse {\n \"iurimateus/luasnip-latex-snippets.nvim\",\n -- vimtex isn't required if using treesitter\n requires = { \"L3MON4D3/LuaSnip\", \"lervag/vimtex\" },\n config = function()\n require'luasnip-latex-snippets'.setup()\n -- or setup({ use_treesitter = true })\n require(\"luasnip\").config.setup { enable_autosnippets = true }\n end,\n}\n```\n\n## Configuration\n\n```\n{\n use_treesitter = false, -- whether to use treesitter to determine if cursor is in math mode; if false, vimtex is used\n allow_on_markdown = true, -- whether to add snippets to markdown filetype\n}\n```\n\n## Misc\n\nThe following convention, from\n[SirVer/ultisnips](https://github.com/SirVer/ultisnips), is used for naming lua\ntables and respective files:\n\n```\nA: Automatic snippet expansion - snippets will activate as soon as their trigger\nmatches.\n\nw: Word boundary - With this option the snippet trigger will match when the\ntrigger is a word boundary character. This is the default behavior.\n\nb: Beginning of line expansion - A snippet with this option is expanded only if\nthe trigger is the first word on the line (i.e., only whitespace precedes the\ntrigger).\n```\n\nNote that the _regex_ term used in LuaSnip is misleading: it is not a POSIX\nregexp. What's actually being used is Lua pattern matching, which has some\nlimitations. In particular, it lacks positive lookbehind and alternation `|`.\nThe first which is used in postfix completions (e.g. match `delta`, but not\n`\\delta`) and can be handled with simple functions. The second was solved by\nsplitting and/or partially rewriting the expressions.\n\n### Adding your own snippets / overrides\n\nSee discussion https://github.com/iurimateus/luasnip-latex-snippets.nvim/discussions/3#discussioncomment-11348745\n\n```lua\nlocal ls = require(\"luasnip\")\nlocal utils =
