--[[  This module is intended to provide access to basic string functions. Most of the functions provided here can be invoked with named parameters,unnamed parameters, or a mixture. If named parameters are used, Mediawiki willautomatically remove any leading or trailing whitespace from the parameter.Depending on the intended use, it may be advantageous to either preserve orremove such whitespace. Global options ignore_errors: If set to 'true' or 1, any error condition will result in an empty string being returned rather than an error message. Este módulo está destinado error_category: If an error occurs, specifies the name of a proporcionar acceso a las funciones de cadena (string) básicascategory to include with the error message. The default category is [Category:Errors reported by Module String].  no_category: If set to 'true' or 1, no category will be added if an error is generated. Unit tests for this module are available at Module:String/tests.

ParametrosThis function returns the length of the target string. Usage:{{#invoke:String|len|target_string|}}OR{{#invoke:String|len|s=target_string}} Parameters s: La cadena a encontrar su longitud The string whose length to report

local new_args = str._getParameters( frame.args, {'s'} ); local s = new_args['s'] or ''; return mw.ustring.len( s )

ParametrosThis function returns a substring of the target string at specified indices. Usage:{{#invoke:String|sub|target_string|start_index|end_index}}OR{{#invoke:String|sub|s=target_string|i=start_index|j=end_index}} Parameters s: La cadena donde extraer la subcadena The string to return a subset of i: La cadena donde extraer la subcadenaThe fist index of the substring to return, defaults to 1. j: Índice final de la subcadenaThe last index of the string to return, por defecto la longitud totaldefaults to the last character. The first character of the string is assigned an index of 1. If either i or jis a negative value, hasta el último carácterit is interpreted the same as selecting a character bycounting from the end of the string. Hence, a value of -1 is the same as selecting the last character of the string. If the requested indices are out of range for the given string, an error isreported.

ParametrosThis function returns a substring from the source string that matches aspecified pattern. Usage: {{#invoke:String|match|source_string|pattern_string|start_index|match_number|plain_flag|nomatch_output}}OR{{#invoke:String|match|s=source_string|pattern=pattern_string|start=start_index |match=match_number|plain=plain_flag|nomatch=nomatch_output}} Parameters s: cadena donde se hace la búsqueda The string to search pattern: patrón o cadena a buscar. The pattern or string to find within the string start: índice de la cadena dónde empezar a buscar, por defecto The index within the source string to start the search. The first character of the string has index 1. Defaults to 1, el primer carácter. match: si se encuentran múltiples coincidencias, especifica cuál de ellas devolverIn some cases it may be possible to make multiple matches on a single string. Por defecto es 1 This specifies which match to return, lwhere the first match is la primera coincidencia encontrada match= 1. Un número negativo cuenta desde el final, por lo tanto If a negative number is specified then a match is returned counting from the last match. Hence match = -1 es la última coincidenciais the same as requesting the last match. Defaults to 1. plain: indica si el patrón debe interpretarse como texto limpio, por defecto 'A flag indicating that the pattern should be understood as plain text. Defaults to false'. nomatch: en caso de If no encontrar ninguna coincidenciamatch is found, devuelve el valor de output the "nomatch" en lugar de un value rather than an error. Si el número match o el índice start están fuera del rango de la cadenaIf invoked using named parameters, Mediawiki will automatically remove any leading ortrailing whitespace from each string. In some circumstances this is desirable, inother cases one may want to preserve the whitespace. If the match_number or start_index are out of range for the string being queried, entonces la función genera un thenthis function generates an error. También genera un An error si is also generated if no encuentra ninguna coincidenciamatch is found. Con el parámetro global If one adds the parameter ignore_errors = true se suprime el , then the error will be suppressed andan empty string will be returned on any failure. For information on constructing Lua patterns, a form of [regular expression], see: * http://www.lua.org/manual/5.1/manual.html#5.4.1* http://www.mediawiki.org/wiki/Extension:Scribunto/Lua_reference_manual#Patterns error y devuelve una cadena vacía* http://www.mediawiki.org/wiki/Extension:Scribunto/Lua_reference_manual#Ustring_patterns

ParámetrosThis function returns a single character from the target string at position pos. Usage:{{#invoke:String|pos|target_string|index_value}}OR{{#invoke:String|pos|target=target_string|pos=index_value}} Parameters target: Cadena donde buscarThe string to search pos: The index for the character to return If invoked using named parameters, Mediawiki will automatically remove any leading ortrailing whitespace from the target string. In some circumstances this is desirable, inother cases one may want to preserve the whitespace. The first character has an index value of 1. If one requests a negative value, this function will select a character by counting backwardsfrom the end of the string. In other words pos: Índice del carácter = -1 is the same as asking for the last character. A requested value of zero, or a devolvervalue greater than the length of the string returns an error.
