Question: Do I need an auto-save plugin for live preview?

[jacob-jacob-jacob]

The browser for me only updates when I write the file (:w). I'm relatively new to VIM, so not sure if this is a problem on my side - the vim configuration is relatively vanilla though.

I do not understand if this should be working, or if a plugin like https://github.com/pocco81/auto-save.nvim is assumed to be installed? If so, would you mind sharing your auto-safe configuration?

Thank you for the great plugin!

[chomosuke]

Nope, that's not supposed to happen. I'd appreciate it if you can share your config so that I can investigate further into this issue.

Hello, thank you very much! This is my config

My init.lua:

local lazypath = vim.fn.stdpath("data") .. "/lazy/lazy.nvim"
if not (vim.uv or vim.loop).fs_stat(lazypath) then
  vim.fn.system({
    "git",
    "clone",
    "--filter=blob:none",
    "https://github.com/folke/lazy.nvim.git",
    "--branch=stable", -- latest stable release
    lazypath,
  })
end
vim.opt.rtp:prepend(lazypath)

-- Example using a list of specs with the default options
vim.g.mapleader = " " -- Make sure to set `mapleader` before lazy so your mappings are correct
vim.g.maplocalleader = "\\" -- Same for `maplocalleader`

local typst_preview = {
  'chomosuke/typst-preview.nvim',
  lazy = false, -- or ft = 'typst'
  version = '0.3.*',
  build = function() require 'typst-preview'.update() end,
}

require("lazy").setup({
    typst_preview
})

Basically, I am only installing the lazy package manager and using an autosave feature (however, it did not work before the autosaving either).

Also, to add, I am on Manjaro linux and NVIM v0.9.5.

I am not supposed to be installing https://github.com/Enter-tainer/typst-preview manually, right? The above should pull in that plugin and work without any other config?

[chomosuke]

Yup, your config are supposed to work. In fact, I copied your config and it did work for me. May I ask what OS are you running? It could also help if you set debug = true and post the output of :mes.

[jacob-jacob-jacob]

Hello. Thanks for the fast answer! I am running Manjaro Linux.

My new config, with debug = true:

local lazypath = vim.fn.stdpath("data") .. "/lazy/lazy.nvim"
if not (vim.uv or vim.loop).fs_stat(lazypath) then
  vim.fn.system({
    "git",
    "clone",
    "--filter=blob:none",
    "https://github.com/folke/lazy.nvim.git",
    "--branch=stable", -- latest stable release
    lazypath,
  })
end
vim.opt.rtp:prepend(lazypath)

-- Example using a list of specs with the default options
vim.g.mapleader = " " -- Make sure to set `mapleader` before lazy so your mappings are correct
vim.g.maplocalleader = "\\" -- Same for `maplocalleader`

local typst_preview = {
  debug = true,
  'chomosuke/typst-preview.nvim',
  lazy = false, -- or ft = 'typst'
  version = '0.3.*',
  build = function() require 'typst-preview'.update() end,
}

require("lazy").setup({
    typst_preview
})

When I open the file with nvim, and then do :TypstPreview, the preview opens correctly. When I then type in some stuff in insert mode (withot saving), :mes does not show me anything.

When I write the file, the preview is updated, and afterwards, :mes shows me

"filename.typ" 183L, 9715B written

but nothing else.

[jacob-jacob-jacob]

I just reinstalled nvim (and deleted everything in .config/nvim as well as .local/share/nvim), and only copied over the above config. But I am still getting the same behaviour as before.

[chomosuke]

Sorry for the late reply. I forgot to tell you how to set debug = true, you need to do this

local typst_preview = {
  'chomosuke/typst-preview.nvim',
  lazy = false, -- or ft = 'typst'
  version = '0.3.*',
  config = function()
    require('typst-preview').setup { debug = true }
  end,
  build = function() require 'typst-preview'.update() end,
}

Hello, I have the same issue. The following is the output of :mes after setting debug:
