getstack

Arguments

number

required

The stack-frame level to inspect. See this function’s frame-numbering rules below.

number

default:"-1"

A 1-based register slot, or -1 to return all frame slots.

Returns

any

One register value, or all selected frame slots when index is -1 or omitted.

Also accepts debug.getstack(thread, level, index). Frame levels are zero-based in frame_at_level; registers are 1-based. -1/omitted index requests a table. Internal executor frames are skipped; C frames and invalid indexes raise. Related types: Debug types & behavior.

local function inspect()
    local value = "docs-slot"
    local ok, slots = pcall(debug.getstack, 1)
    print(ok, slots, value)
end
inspect()
