Usage

1. Setup typst-lsp. (see example here)

2. Call require("typst-preview").preview().

How it works

1. Generate pdf files by typst compile.
2. Respond to subsequent file changes with typst-lsp.
3. Redirect these pdf files to a fixed path when you switch buffer.
4. Preview this pdf by a pdf viewer with the ability to respond to the file changes.

Dependencies

• typst (typst compile command)
• typst-lsp
• niuiic/core.nvim
• pdf viewer (recommend okular)

Config

Default configuration here.

{
	-- file opened by pdf viewer
	output_file = function()
		local core = require("core")
		return core.file.root_path() .. "/output.pdf"
	end,
	-- how to redirect output files
	redirect_output = function(original_file, output_file)
		vim.cmd(string.format("silent !ln -s %s %s", original_file, output_file))
	end,
	-- how to preview the pdf file
	preview = function(output_file)
		local core = require("core")
		core.job.spawn("mimeopen", {
			output_file,
		}, {}, function() end, function() end, function() end)
	end,
	-- whether to clean all pdf files on VimLeave
	clean_temp_pdf = true,
}

Notice

Shell commands ln and mimeopen are used by default. You may need alternatives if they don't exist.

The first time you execute mimeopen command, it requires you to set the default application, please run the command manually first, complete the settings before using the plugin.

It is recommended to enable this plugin as soon as reading a typst file, or temp pdf files cannot be cleaned completely.

Compare to other tools

typst-live is awesome. However, severe flickering occurs when the file is updated. This is the limitation of the browser. In addition, it cannot switch files.

chomosuke/typst-preview.nvim supports cross jumping between code and preview, but does not support file switching yet. It should be noted that typst-preview used by this plugin implements the rendering logic itself instead of using official tools.
