# luasnip-latex-snippets

A port of [Gilles Castel's](https://github.com/gillescastel/latex-snippets)

snippets for the [LuaSnip Engine](https://github.com/L3MON4D3/LuaSnip).

## Why?

UltiSnips felt unbearably slow. See

 and

.

## Installation

Depends on [vimtex](https://github.com/lervag/vimtex) to determine if the

cursor is within math mode. Alternatively, you can use

[nvim-treesitter](https://github.com/nvim-treesitter/nvim-treesitter) (experimental) by passing `{ use_treesitter = true }` to the setup call.

It's necessary to enable `autosnippets` in luasnip: `require("luasnip").config.setup { enable_autosnippets = true }`.

Can be installed like any neovim plugin. If using

[wbthomason/packer.nvim](https://github.com/wbthomason/packer.nvim):

```lua

use {

  "iurimateus/luasnip-latex-snippets.nvim",

  -- vimtex isn't required if using treesitter

  requires = { "L3MON4D3/LuaSnip", "lervag/vimtex" },

  config = function()

    require'luasnip-latex-snippets'.setup()

    -- or setup({ use_treesitter = true })

    require("luasnip").config.setup { enable_autosnippets = true }

  end,

}

```

## Configuration

```

{

  use_treesitter = false, -- whether to use treesitter to determine if cursor is in math mode; if false, vimtex is used

  allow_on_markdown = true, -- whether to add snippets to markdown filetype

}

```

## Misc

The following convention, from

[SirVer/ultisnips](https://github.com/SirVer/ultisnips), is used for naming lua

tables and respective files:

```

A: Automatic snippet expansion - snippets will activate as soon as their trigger

matches.

w: Word boundary - With this option the snippet trigger will match when the

trigger is a word boundary character. This is the default behavior.

b: Beginning of line expansion - A snippet with this option is expanded only if

the trigger is the first word on the line (i.e., only whitespace precedes the

trigger).

```

Note that the _regex_ term used in LuaSnip is misleading: it is not a POSIX

regexp. What's actually being used is Lua pattern matching, which has some

limitations. In particular, it lacks positive lookbehind and alternation `|`.

The first which is used in postfix completions (e.g. match `delta`, but not

`\delta`) and can be handled with simple functions. The second was solved by

splitting and/or partially rewriting the expressions.
