A string rewriting system (SRS), also known as semi-Thue system, exploits the free monoid structure of the strings (words) over an alphabet to extend a rewriting relation, , to all strings in the alphabet that contain left- and respectively right-hand sides of some rules as substrings.
A string homomorphism (often referred to simply as a homomorphism in formal language theory) is a string substitution such that each character is replaced by a single string. That is, f ( a ) = s {\displaystyle f(a)=s} , where s {\displaystyle s} is a string, for each character a {\displaystyle a} .
A string datatype is a datatype modeled on the idea of a formal string. ... (replacing repeated characters by the character value and a length) ...
Returns string with the first n occurrences of target replaced with replacement. Omitting count will replace all occurrences. Space counts as a character if placed in any of the first three parameters.
In computer programming, string interpolation (or variable interpolation, variable substitution, or variable expansion) is the process of evaluating a string literal containing one or more placeholders, yielding a result in which the placeholders are replaced with their corresponding values.
The text editor could replace this byte with the replacement character to produce a valid string of Unicode code points for display, so the user sees "f r". A poorly implemented text editor might write out the replacement character when the user saves the file; the data in the file will then become 0x66 0xEF 0xBF 0xBD 0x72.
This function allows one to replace a target string or pattern within another string. To Lua programmers: this function works internally by calling mw.ustring.gsub. Usage: {{#invoke:String|replace|source_str|pattern_string|replace_string|replacement_count|plain_flag}} OR
