# Filesystem and serialization
|
|
|
|
### *file* library
|
|
|
|
See [file library](builtins/libfile.md)
|
|
|
|
## *json* library
|
|
|
|
The library contains functions for serializing and deserializing tables:
|
|
|
|
```python
|
|
json.tostring(object: table, human_readable: bool=false) -> str
|
|
```
|
|
|
|
Serializes an object into a JSON string. If the second parameter is **true**, multi-line human-readable formatting will be used, rather than the compact format used by default.
|
|
|
|
```python
|
|
json.parse(code: str) -> table
|
|
```
|
|
|
|
Parses a JSON string into a table.
|
|
|
|
## *toml* library
|
|
|
|
The library contains functions for serializing and deserializing tables:
|
|
|
|
```python
|
|
toml.tostring(object: table) -> str
|
|
```
|
|
|
|
Serializes an object into a TOML string.
|
|
|
|
```python
|
|
toml.parse(code: str) -> table
|
|
```
|
|
|
|
Parses a TOML string into a table.
|
|
|
|
## *yaml* library
|
|
|
|
The library contains functions for serializing and deserializing tables:
|
|
|
|
```python
|
|
yaml.tostring(object: table) -> str
|
|
```
|
|
|
|
Serializes an object into a YAML string.
|
|
|
|
```python
|
|
yaml.parse(code: str) -> table
|
|
```
|
|
|
|
Parses a YAML string into a table.
|
|
|
|
## *bjson* library
|
|
|
|
The library contains functions for working with the binary data exchange format [vcbjson](../../specs/binary_json_spec.md).
|
|
|
|
```lua
|
|
-- Encodes a table into a byte array
|
|
bjson.tobytes(
|
|
-- encoded table
|
|
value: table,
|
|
-- compression
|
|
[optional] compression: bool=true
|
|
) --> Bytearray
|
|
|
|
-- Decodes a byte array into a table
|
|
bjson.frombytes(bytes: table | Bytearray) --> table
|
|
```
|
|
|
|
## Storing data in a world
|
|
|
|
When saving pack data in the world, you should use the function:
|
|
|
|
```python
|
|
pack.data_file(packid: str, filename: str) -> str
|
|
```
|
|
|
|
Returns data file path like: `world:data/packid/filename`
|
|
and creates missing directories.
|
|
|
|
If paths other than `data/{packid}/...` are used, data may be lost.
