rep(1) not working (empty)

[axieax]

Hi, I'm trying to make a snippet for a Lua module. However, I'm not sure how to repeat the highlighted node with index 1 from the previous / upper level (not in the same curly brace). Is there a way I can achieve this?

Uhh nice, a usecase for absolute_indexer :D
Passing (with local ai = require("luasnip.nodes.absolute_indexer")) ai[1] instead of 1 should do the trick.
Check in DOC.md or :h luasnip-absolute_indexer for more info

Yeah kinda hard to explain, apologies for the confusions!

Ahhhh alright: the choiceNode is jumped into, but there is no position at which the cursor could stop (ie. an insertNode) inside it, so it's just jumped over.
Adding an i(1) somewhere (the beginning, probably) should prevent that

Do you mean something like this? Not sure why it's still not working rip

local mod = s(
  "mod",
  fmt(
    [[
    local {} = {{}}
    {}
    return {}
    ]],
    {
      i(1, "M"),
      c(2, {
        i(1),
        t(""),
        fmt(
          [[
            function {}.config()
            end
          ]],
          { rep(ai[1]) }
        ),
        fmt(
          [[
            function {}.setup()
            end

            function {}.config()
            end
          ]],
          { rep(ai[1]), rep(ai[1]) }
        ),
      }),
      c(3, {
        i(1),
        rep(ai[1]),
        fmt("setmetatable({}, {{}})", { rep(ai[1]) }),
      }),
    }
  )
)

Ahh, "no position to stop in the active choice" is what I should've said.
so

fmt(
          [[
            function {}.config()
            end
          ]],
          { rep(ai[1]) }

to

fmt(
          [[
            {}function {}.config()
            end
          ]],
          { i(1), rep(ai[1]) }

Ahh I got it now! Cheers for the followup :))
