Everything I need to not forget. This is my basic configuration for TeXpresso on Neovim, specifically Lazyvim.

Video Example

From the TeXpresso repository.

Setup

Installation

Follow these instructions.

Configuration

In ~/.config/nvim/lua/plugins/texpresso.lua:

return {
  {
    "let-def/texpresso.vim",
    ft = "tex", -- load only for TeX files for efficiency
    config = function()
      -- Set the custom path to your texpresso binary
      require("texpresso").texpresso_path = "/home/yourname/dev/texpresso/texpresso"
    end,
  }
}

In ~/.config/nvim/lua/config/keymamps.lua:

vim.keymap.set(
  "n",
  "<leader>öt", -- Or whatever you may want to use as a keymap
  ":TeXpresso %<CR>",
  vim.tbl_extend("force", opts, { desc = "Run TeXpresso on current file" })
)
