'expandtab'-agnostic indentation

[kraftwerk28]

Is it possible to create a multiline snippet that would have an indentation based on et/ts/sw options in the buffer?
For example:

s(
  "ie=",
  fmt([[
    if err := {}; err != nil {{
    {}{}
    }}
  ]], { i(1), agnostic_indent_node(), i(0) })
)

The agnostic_indent_node should insert a single tab if noexpandtab is set, 2 spaces if expandtab, shiftwidth=2 etc.

idea: In Ultisnips, a tab in the snippet would do exactly that (match the tab/space config of the buffer), maybe LuaSnip could copy this behavior?

The machinery is in place, maybe is just that the fmt helper is not using it.

Hm, I just realized that LuaSnip also has this behavior, i.e. t("\t") matches et/sw/ts. Thank you.

Try:

    s(
      "ie=",
      fmt([[
        if err := {}; err != nil {{
        {}{}
        }}
      ]], { i(1), t"\t", i(0) })
    ),
