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 will automatically remove any leading or trailing whitespace from the

Remove all text between delimiters, including the delimiters themselves. getPlain Remove wikimarkup (except templates): comments, tags, bold, italic, nbsp isLatinRange Returns some content, unless the string contains a character that would not normally be found in Latin text. Returns nothing if there is a non-Latin string. isQuote
source_string The string to count occurrences in pattern The string or pattern to count occurrences of within source plain Boolean flag indicating that pattern should be understood as plain text and not as a Scribunto ustring pattern (a unicode-friendly Lua-style regular expression); defaults to true. Examples:
This function may return 0 when the needle is found at the begining of the haystack, so it might be misinterpreted as false value by another comparative operator. The better way is to use == or !== for testing whether it is found. str_replace: Replaces all occurrences of the search string with the replacement string.
The constructor is a node in a tree and the integer and string are leaves in branches. When we want to write functions to make Color an abstract data type, we wish to write functions to interface with the data type, and thus we want to extract some data from the data type, for example, just the string or just the integer part of Color.
A simple and inefficient way to see where one string occurs inside another is to check at each index, one by one. First, we see if there is a copy of the needle starting at the first character of the haystack; if not, we look to see if there's a copy of the needle starting at the second character of the haystack, and so forth.
The Boyer–Moore algorithm searches for occurrences of P in T by performing explicit character comparisons at different alignments. Instead of a brute-force search of all alignments (of which there are n − m + 1 {\displaystyle n-m+1} ), Boyer–Moore uses information gained by preprocessing P to skip as many alignments as possible.
