Build, test, and debug regular expressions
This regular expression captures consecutive sequences of non-whitespace characters (words) that may be followed by any number of periods and then optional whitespace. It effectively splits text into word tokens while stripping trailing punctuation and separating spaces. Useful for basic tokenization, keyword extraction, or parsing simple command-line input where each word is delimited by spaces. The global and multiline flags allow it to be applied repeatedly across all lines of input.
