## Core functions
## Namespaces
Currently, the engine uses a namespace hierarchy that minimizes conflicts between individual modules, scripts, and even packs.
The following structure is relevant:
- Global namespace (_G), which is the root namespace. Writing to it outside of engine core modules is highly undesirable, as it can waste hours of debugging time.
- Pack namespace - created each time content is loaded for each pack included in the configuration. This namespace is used by modules, as well as item and block scripts.
- [Component namespace](scripting/ecs.md#built-in-components).
- [UI document namespace](scripting/ui.md).
- Isolated world generator namespace.
## Modules
A module is a global object with a lifetime limited to the lifetime of the loaded content, used both for interaction between different packages and as a substitute for global variables within the package itself.
The module must be located in `contentpack/modules/**` (subfolders are allowed, but you will need to specify them)
```lua
require "packid:module_name" -- load Lua module from pack-folder/modules/
-- no extension included, just name
local module_name = require "contentpack:module_name" -- imports the module
-- If the module is in the same pack in which it is imported, you can use the shortcut:
local module_name = require "module_name"
-- When using nested folders:
local module_name = require "contentpack:path/to/module_name" -- the path does not include `modules`
local module_name = require "path/to/module_name" -- if in the same pack
```
The module will have the namespace of the folder in which it is located, regardless of the namespace from which the first import was performed.
When creating a module, you should follow the following approach, which is what *require* expects:
```lua
local this = {
variable_name = ... -- public variables
}
-- private module variables
local variable_name = ...
-- private module functions
local function function_name(...)
...
end
-- public module functions
function this.function_name(...)
...
end
return this -- the result that require will return and cache
```
When reimported, the module will not be reloaded; instead, require will return the cached result.

## Custom Components
A component is defined as a script in `{pack}/scripts/components/{name}.lua`.
The component will be available for use in the entity definition as `{pack}:{name}`.
Example: `core:scripts/components/pathfinding.lua` -> `core:pathfinding`.
For **each** entity containing a component, a **separate instance** is created with **its own namespace** within the pack namespace.
Global variables declared in it act as public fields of the component (same for global functions).
Entity components are specified via the ["components" list](../entity-properties.md#components)

## Table Extensions
```lua
-- Creates and returns a copy of the given table by creating a new one and copying all elements from the given table into it.
table.copy(t: table) -> table
-- The deep copy function creates a full copy of the source table, including all its subtables.
table.deep_copy(t: table) -> table
-- Returns the number of pairs in the given table.
table.count_pairs(t: table) -> int
-- Returns one element from the given table at a random position.
table.random(t: table) -> any
-- Returns true if x is contained in t.
table.has(t: table, x: any) -> boolean
-- Returns the index of x in t. If the given object is not contained in the table, the function returns -1.
table.index(t: table, x: any) -> int
-- Removes element x from t.
table.remove_value(t: table, x: any)
-- Shuffles values ​​in the table.
table.shuffle(t: table) -> table
-- Adds values ​​from table t2 to table t1. If table t2 contains a key from t1, the key's value will not be changed.
table.merge(t1: table, t2: table) -> table
-- Iterates through the table and applies a func to all its elements, returning the new value of the element.
table.map(t: table, func: function(indx, value)) -> table
-- Iterates through the table using a func that returns true if the element should be kept and false if it should be deleted.
table.filter(t: table, func: function(indx, value)) -> table
-- Allows you to safely retrieve the value for the specified key. If the key exists in the table, the method will return its value.
-- If the key is missing, the method will set it to the default value and return it.
table.set_default(t: table, key: int | string, default: any) -> any
-- Returns a "flattened" version of the original table.
table.flat(t: table) -> table
-- Returns a deep "flat" version of the original table.
table.deep_flat(t: table) -> table
-- Returns a truncated version of the table from index start to index stop, inclusive. Key-value pairs
-- are not preserved in the new table. For nil values, the value starts at 1 and ends at #arr, respectively.
table.sub(arr: table, start: number | nil, stop: number | nil) -> table
-- Adds a value to the table only if it was not originally there.
table.insert_unique(t: table, val: any)
table.insert_unique(t: table, pos: int, val: any)
-- Returns a table containing all keys of the given table, including numeric ones. table.keys(t: table) -> table
-- Adds all key-value pairs from table extension to table t. If a key from t is present in extension, its value will be overwritten.
table.extend(t: table, extension: table) -> table
-- Converts the passed table to a string.
table.tostring(t: table) -> string
```
## String extensions
It's important to note that all of the functions listed below that extend **string** can be used as meta-methods on string instances, i.e.:
```lua
local str = "ABA str BAB"
if str:starts_with("ABA") and str:ends_with("BAB") then
print(str:replace("BA", "DC"))
end
```
```lua
-- Splits the string into parts based on the specified separator/expression and returns the result as a table of strings. If withpattern is true, the separator parameter will be evaluated as a regular expression. string.explode(separator: string, str: string, withpattern: boolean) -> table<string>
-- Splits the string into parts based on the specified delimiter and returns the result as a table of strings.
string.split(str: string, delimiter: string) -> table<string>
-- Escapes special characters in the string, such as `()[]+-.$%^?*`, into `%character` format. The `NUL` character (`\0`) will be converted to `%z`.
string.pattern_safe(str: string) -> string
-- Splits seconds into hours, minutes, and milliseconds and formats them using the following parameter order: `minutes, seconds, milliseconds`, and then returns the result. If format is not specified, it returns a table where:
-- h - hours,
-- m - minutes,
-- s - seconds,
-- ms - milliseconds.
string.formatted_time(seconds: number, format: string) -> string | table
-- Replaces all substrings in str equal to tofind with toreplace and returns a string with all the modified substrings.
string.replace(str: string, tofind: string, toreplace: string) -> string
-- Removes all characters equal to char from the string from the left and right ends and returns the result.
-- If the char parameter is undefined, all empty characters will be selected.
string.trim(str: string, char: string) -> string
-- Removes all characters equal to char from the string from the left end and returns the result.
-- If the char parameter is undefined, all empty characters will be selected.
string.trim_left(str: string, char: string) -> string
-- Removes all characters equal to char from the right end of the string and returns the result.
-- If the char parameter is undefined, all empty characters will be selected.
string.trim_right(str: string, char: string) -> string
-- Returns true if the string begins with the substring start.
string.starts_with(str: string, start: string) -> boolean
-- Returns true if the string ends with the substring endStr.
string.ends_with(str: string, endStr: string) -> boolean
-- The string.lower and string.upper functions are also overridden by utf8.lower and utf8.upper.
-- Escapes a string. It is an alias for utf8.escape.
string.escape(str: string) -> string
-- Escapes special XML characters. An alias for utf8.escape_xml.
string.escape_xml(text: string) -> string
-- Adds a char to the left and right of the string until its size equals size.
-- By default, char is equal to the space character.
string.pad(str: string, size: int, char: string) -> string
-- Adds a char to the left of the string until its size equals size.
-- By default, char is equal to the space character.
string.left_pad(str: string, size: int, char: string) -> string
-- Adds a char to the right of the string until its size equals size.
-- By default, char is equal to the space character.
string.right_pad(str: string, size: int, char: string) -> string
```
## Math extensions
```lua
-- Returns _in if it is in the range low <= _in <= high
-- Otherwise, returns the boundary to which _in is closest.
math.clamp(_in: number, low: number, high: number) -> number
-- Returns a random fractional number in the range low to high.
math.rand(low: number, high: number) -> number
-- Returns the normalized value of num relative to conf.
math.normalize(num: number, [optional] conf: number) -> number
-- Returns the rounded value of num to the specified number of decimal places.
math.round(num: number, [optional] places: number) -> number
-- Returns the sum of all received arguments. If a table was passed as an argument, the method will return the sum of all its elements.
math.sum(x: number, ... | t: table) -> number
```
## Bit extensions
```lua
-- Common arguments:
-- * expr: A string containing a bitwise expression, conforming to the Lua 5.3 bitwise operations format
-- * args: A list of names of the expression arguments. If nil, the list is automatically generated based on the detected identifiers.
- Compiles the function to perform bitwise operations
-- * asFunction: If true, returns the function; otherwise, returns a string of function code
bit.compile(expr: string, args: table | nil, asFunction: boolean=true) -> function | string
-- Compiles the function to perform bitwise operations and executes it in place
-- * ...: Values ​​to be passed to the compiled function. bit.execute(expr: string, args: table | nil, ...) -> number
```
## Additional Global Functions
This script also defines other global functions that are available for use. Their list is below.
```lua
-- Returns true if the passed table is an array, that is, if each key is an integer greater than or equal to one
-- and if each key follows the previous one.
is_array(x: table) -> boolean
-- Splits the path into two parts and returns them: the entry point and the file path.
parse_path(path: string) -> string, string
-- Calls the function func iters times, passing it the arguments ..., and then prints to the console the time in microseconds that has elapsed
-- since the call to timeit. timeit(iters: int, func: function, ...)
-- Causes the coroutine to pause until the number of seconds specified in timesec has elapsed.

Parses a YAML string into a table.
## XML Library
The library contains functions for serializing and deserializing XML:
Further, XML as a data type denotes a Lua table with the following structure:
- Element tag is accessible by the key `#`
- XML ​​attributes are accessible as key = value pairs
- Inner elements are accessible by index
The table is used both as a dictionary and an array.
Example:
```xml
<panel size='400' color='0' interval='1' context='menu'>
<button onclick='menu.page="worlds"'>@Worlds</button>
</panel>
```
Equivalent Lua table:
```lua
{
['#'] = "panel",
size = "400",
color = "0",
interval = "1",
context = "menu",
{
['#'] = "button",
onclick = 'menu.page="worlds"',
{
"@Worlds"
}
}
}
```
Consequently, the button element is accessible as `panel_element[1]`.
```lua
-- Serializes a tree in XML format
-- multiline - use multiline formatting
xml.tostring(data: XML, multiline: bool = true) -> str
-- Parses XML
xml.parse(code: str) -> XML
-- Parses the VCD (VoxelCore Declaration) format used by the VCM format.
-- root_tag - a root element with the specified tag will be implicitly created,
-- containing all root elements
xml.parse_vcd(code: str, root_tag: str = "root") -> XML
```
## *bjson* library
The library contains functions for working with the binary data exchange format [vcbjson](../../specs/binary_json_spec.md).

## Пространства имён
В настоящее время, движок использует иерархию пространств имён, минимизирующую конфликты между отдельными модулями, скриптами, да и паками.
Актуальна следующая структура:
- Глобальное пространство (оно же - _G), являющееся корневым, запись в которое, вне модулей ядра движка, является крайне нежелательным для вашего же времени, что может уйти на лишние часы отладки.
- Пространство пака - создаётся каждый раз при загрузке контента для каждого, включённого в конфигурацию, пака. Это пространство используют модули, а также скрипты предметов и блоков.
- Пространство [компонента](scripting/ecs.md#пользовательские-компоненты).
- Пространство [UI-документа](scripting/ui.md)
- Изолированное пространство имён генератора мира.
## Модули
Модуль - глобальный объект со сроком жизни, ограниченным сроком жизни контента, используемый как для взаимодействия разных паков, так и для вместо глобальных переменных в пределах самого пака.
Модуль должен находиться в `контентпак/modules/**` (допускаются вложенные папки, что нужно будет указывать)
```lua
require "контентпак:имя_модуля" -- загружает lua модуль из папки modules (расширение не указывается)
local имя_модуля = require "контентпак:имя_модуля" -- импортирует модуль
-- если модуль находится в том же паке, в котором импортируется, можно использовать сокращённый вариант:
local имя_модуля = require "имя_модуля"
-- при использовании вложенных папок:
local имя_модуля = require "контентпак:путь/к/имя_модуля" -- путь не включает `modules`
local имя_модуля = require "путь/к/имя_модуля" -- если в том же паке
```
Модуль будет иметь пространство имён того пака, в котором находится, независимо от пространства имён, из которого был выполнен первый импорт.
При создании модуля следует придерживаться следующего подхода, которого и ожидает *require*:
```lua
local this = {
имя_переменной = ... -- публичные переменные
}
-- приватные переменные модуля
local имя_переменной = ...
-- приватные функции модуля
local function имя_функции(...)
...
end
-- публичные функции модуля
function this.имя_функции(...)
...
end
return this -- результат, который и будет возвращать и кешировать require
```
При повторном импорте модуль не будет перезагружен - вместо этого require вернёт кешированный результат.

Таблица используется как словарь, так и массив.
