Command Group: Strings - Regular Expression – Category

patterns can have flags, similar to Javascript by specifying /flags at the end of the pattern. Flags need to be lowercase, if there are any non-flag characters in the flags they will be ignored and considered part of the pattern itself.

Available flags:

• g - global (only relevant for replace/find, missing global flag sets format_first_only flag https://en.cppreference.com/w/cpp/regex/match_flag_type and only replaces first occurence, only returns first element with regexFind)
• i - Case insensitive
• n - nosubs (https://en.cppreference.com/w/cpp/regex/syntax_option_type)
• o - optimize (Optimize pattern, pattern creation is slower, but will execute more efficiently, https://en.cppreference.com/w/cpp/regex/syntax_option_type)

If you don't specify any flags, the default flags are set to /gi, its valid to specify / to indicate no flags, first match only, case sensitive
