Refer to the documentation of the setting for a list of valid placeholders.

For setting a cube, this is 1.3x faster than set_node whereas LVM is 20
times faster.
* `minetest.swap_node(pos, node)`
* Set node at position, but don't remove metadata
* `minetest.remove_node(pos)`
* By default it does the same as `minetest.set_node(pos, {name="air"})`
* Swap node at position with another.
* This keeps the metadata intact and will not run con-/destructor callbacks.
* `minetest.remove_node(pos)`: Remove a node
* Equivalent to `minetest.set_node(pos, {name="air"})`, but a bit faster.
* `minetest.get_node(pos)`
* Returns the node at the given position as table in the format
`{name="node_name", param1=0, param2=0}`,
returns `{name="ignore", param1=0, param2=0}` for unloaded areas.
* Returns the node at the given position as table in the same format as `set_node`.
* This function never returns `nil` and instead returns
`{name="ignore", param1=0, param2=0}` for unloaded areas.
* `minetest.get_node_or_nil(pos)`
* Same as `get_node` but returns `nil` for unloaded areas.
* Note that areas may still contain "ignore" despite being loaded.
* Note that even loaded areas can contain "ignore" nodes.
* `minetest.get_node_light(pos[, timeofday])`
* Gets the light value at the given position. Note that the light value
