# Legacy Code Support Functions
|
|
|
|
## `vl_legacy.deprecated(description, replacement)`
|
|
|
|
Creates a wrapper that logs calls to deprecated function.
|
|
|
|
Arguments:
|
|
* `description`: The text logged when the deprecated function is called.
|
|
* `replacement`: The function that should be called instead. This is invoked passing
|
|
along the parameters exactly as provided.
|
|
|
|
## `vl_legacy.register_item_conversion`
|
|
|
|
Allows automatic conversion of items.
|
|
|
|
Arguments:
|
|
* `old`: Itemstring to be converted
|
|
* `new`: New item string
|
|
|
|
## `vl_legacy.convert_node(pos, node)`
|
|
|
|
Converts legacy nodes to newer versions.
|
|
|
|
Arguments:
|
|
* `pos`: Position of the node to attempt conversion
|
|
* `node`: Node definition to convert. The node will be loaded from map data if `nil`.
|
|
|
|
The node definition for the old node must contain the field `_vl_legacy_convert` with
|
|
a value that is either a `function(pos, node)` or `string` for this call to have any
|
|
affect. If a function is provided, the function is called with `pos` and `node` as
|
|
arguments. If a string is provided, a node name conversion will occur.
|
|
|
|
This mod provides an LBM and ABM that will automatically call this function for nodes
|
|
with `group:legacy` set.
