rex.flags

Summary

Returns a table of PCRE flags

Prototype

flag_table = rex.flags ()


Description

This returns a table of PCRE flags. You can index into this to get various compile and runtime flags.

The following are valid compile-time flags:


  • ANCHORED
  • CASELESS
  • DOLLAR_ENDONLY
  • DOTALL
  • EXTENDED
  • EXTRA
  • MULTILINE
  • NO_AUTO_CAPTURE
  • UNGREEDY
  • UTF8



The following are valid execution-time flags:


  • ANCHORED
  • NOTBOL
  • NOTEOL
  • NOTEMPTY


An example of using the flags would be:


re = rex.new ("(.+) goes (.+)", rex.flags ().CASELESS)


This would make a caseless regular expression.
