withsuffix

Withsuffix is a term used in programming and data processing to describe a utility or function that attaches a suffix to a string or to each element in a sequence. The concept is not tied to a single language or standard library; it appears in various libraries as an operation named withsuffix, add_suffix, or append_suffix.

Typical behavior and parameters

A withsuffix operation generally takes at least two operands: a base value (a string or a collection of strings) and a suffix string. Optional parameters may include a condition, a pattern, or a mapper function to determine when the suffix should be applied. When the base is a list, the operation often applies the suffix to each element; when the base is a single string, it returns the concatenated result. Some implementations support conditional suffixing, such as only adding the suffix if the base does not already end with it or if the base matches a given pattern.

Examples

Applying withsuffix to "report" with the suffix ".txt" yields "report.txt". Applying withsuffix to ["chapter1","chapter2"] with the suffix ".md" yields ["chapter1.md","chapter2.md"]. Conditional forms may add the suffix only when certain criteria are met, for example, skipping the suffix if the base already ends with the target ending.

Relation and variants

Withsuffix is related to other string-manipulation operations like adding a fixed suffix, appending a suffix, or composing transformations. Similar concepts appear under names such as add_suffix or suffix, depending on the library or language.
