I find PCRE's rule easy enough: for a character you want to be taken literally, if it's punctuation backslash it, if it's not then don't; any unbackslashed punctuation (or backslashed non-punctuation) may be a metacharacter. Compare to, say, POSIX or Vim[0] REs, where some punctuation characters are special with a backslash, others are special without, and I can never remember which is which. [0] Regardless of the state of the "magic" option - the only way to get consistent behavior is to start every single RE with either \v (which works like PCRE) or \V (which works like your proposal). |
