FAQ

Q: How do I define a custom provider?

-
require('preview').setup({
-  rst = {
-    cmd = { 'rst2html' },
-    args = function(ctx)
-      return { ctx.file, ctx.output }
-    end,
-    output = function(ctx)
-      return ctx.file:gsub('%.rst$', '.html')
-    end,
-  },
-})
-

Q: How do I override a preset?

-
require('preview').setup({
-  typst = { env = { TYPST_FONT_PATHS = '/usr/share/fonts' } },
-})
-

Q: How do I automatically open the output file?

-

Set open = true on your provider (all built-in presets -have this enabled) to open the output with vim.ui.open() -after the first successful compilation in toggle/watch mode. For a -specific application, pass a command table:

-
require('preview').setup({
-  typst = { open = { 'sioyek', '--new-instance' } },
-})
