Detailed Description

Implements the OP_PCRE2_TEST opcode (conditional build).

Tests whether a PCRE2 pattern matches a subject string and returns 1 on success or 0 otherwise when FUN_WITH_PCRE2 is enabled. When PCRE2 support is disabled at build time, the opcode always returns 0.

OP_PCRE2_TEST

case OP_PCRE2_TEST

OP_PCRE2_TEST: (pattern:any, text:any, flags:int|bool=0) -> int

Behavior when FUN_WITH_PCRE2 is enabled:

• Pops: pattern, text, flags. Converts pattern/text to strings.
• Flags bits:
  • 1 = PCRE2_CASELESS (I)
  • 2 = PCRE2_MULTILINE (M)
  • 4 = PCRE2_DOTALL (S)
  • 8 = PCRE2_UTF (U)
  • 16 = PCRE2_EXTENDED (X)
• Returns 1 if pcre2_match() returns a non-negative result, else 0.
• On compile error or allocation failure, returns 0.

Behavior when FUN_WITH_PCRE2 is disabled:

• Pops three values and returns 0.
