metacat.nvim

Render diagrams from a metacat file from nvim. Assumes metacat-cli is installed.

To configure using Lazy.nvim, add this to plugins.lua:

{
  "statusfailed/metacat.nvim",
  opts = {
    viewer = { "svgtail" },
  },
},

Then bind the render method to a key (e.g. F6 below) by adding the following to init.lua:

vim.keymap.set("n", "<F6>", require("metacat").render, { desc = "Metacat: render def-arrow as SVG" })

Configuration

The configuration above uses svgtail to render SVGs. You can use other programs by setting the viewer opt, e.g. for feh:

viewer = { "feh", "--reload", "1" }

viewer should be a command which:

• Launches with the path to an SVG as its final argument
• Will auto-reload the file when the file path changes
