factory regex

Description:

  • Specifies the regular expression (regex) specific functions.

    • The regex pattern is a string with a special syntax that describes what constitutes a match, using the ECMAScript syntax.
    • It appears that some regex catching multiline string may fail or induce infinite loops:
      • The solution is to convert a multiline string into a single line string, e.g.:
        aidesys::regexReplace(aidesys::regexReplace(string, "\\s+", " "), regex_for_single_line, output)
    • These functions are accessible via the aidesys:: prefix.
