value: The value to convert to a string. This can be any Lua value. This parameter is optional, and defaults to nil. options: A table of options. This parameter is optional. The following options can be specified in the options table: pretty: If true, output the string in "pretty" format (as in pretty-printing). This will add new lines and ...
MessagePack is more compact than JSON, but imposes limitations on array and integer sizes.On the other hand, it allows binary data and non-UTF-8 encoded strings. In JSON, map keys have to be strings, but in MessagePack there is no such limitation and any type can be a map key, including types like maps and arrays, and, like YAML, numbers.
This module provides a consistent interface for processing boolean or boolean-style string input. While Lua allows the true and false boolean values, wikicode templates can only express boolean values through strings such as "yes", "no", etc. This module processes these kinds of strings and turns them into boolean input for Lua to process.
Lua is intended to be embedded into other applications, and provides a C API for this purpose. The API is divided into two parts: the Lua core and the Lua auxiliary library. [20] The Lua API's design eliminates the need for manual reference counting (management) in C code, unlike Python's API. The API, like the language, is minimalist.
Note: Lua patterns are not regular expressions in the traditional POSIX sense, and they are not even a subset of regular expressions. But they share many constructs with regular expressions (more below). Lua patterns are used to define, find and handle a pattern in a string. It can do the common search and replace action in a text, but it has ...
Regular expressions (or regex) are a common and very versatile programming technique for manipulating strings. On Wikipedia you can use a limited version of regex called a Lua pattern to select and modify bits of text from a string. The pattern is a piece of code describing what you are looking for in the string.
Lua has a Boolean data type, but non-Boolean values can also behave as Booleans. The non-value nil evaluates to false, whereas every other data type value evaluates to true. This includes the empty string "" and the number 0, which are very often considered false in other languages.
If it isn't a table, it's a string, a number, a boolean, a function, or a nil. Libraries are tables. string.gmatch is the "gmatch" entry in the table named by the global variable string. Arguments that you receive from MediaWiki are tables. But they're a bit special. Arrays are tables that follow a specific convention.
