nabla.nvim

-----------



Take your scentific notes in Neovim.










The colorscheme used here is [tokyonight](https://github.com/folke/tokyonight.nvim).



An ASCII math generator from LaTeX equations.



Requirements

------------



* Neovim nightly

* A colorscheme which supports treesitter [see here](https://github.com/rockerBOO/awesome-neovim#tree-sitter-supported-colorscheme)

* Tree-sitter : [nvim-treesitter/nvim-treesitter](https://github.com/nvim-treesitter/nvim-treesitter)

* Latex parser : Install with `TSInstall latex`.



Install

-------



  Using vim-plug



  ```vim

  Plug 'jbyuki/nabla.nvim'

  ```



  Using packer.nvim



  ```vim

  use 'jbyuki/nabla.nvim'

  ```



  Using the built-in package manager



  * Create a folder `pack//start`

  * Inside the `start` folder `git clone` nabla.nvim

    * `git clone https://github.com/jbyuki/nabla.nvim`

  * In your init.lua, add the pack folder to packpath (see `:help packpath`)

    ```lua

    vim.o.packpath = vim.o.packpath .. ","

    ```



  * `git pull` in the plugin folder to update it. You want something more viable

  though, that's why package managers are useful.




Configuration

-------------



Bind the following command:



```vim

nnoremap p :lua require("nabla").popup() " Customize with popup({border = ...})  : `single` (default), `double`, `rounded`

```



See [here](https://github.com/jbyuki/nabla.nvim/issues/35) for virt_lines support.



Usage

-----



* Press leader + p while the cursor is on a math expression to open floating menu
