Dependencies

- 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.
