Reference

​
new

Constructs a new regex matcher from a regular expression string. The regex syntax follows Rust’s regex crate, which supports standard Perl-style regular expressions.

​
is_match

Returns true if the regex matches the given text string, false otherwise. Optionally takes a second parameter specifying the starting position to begin matching from. If not provided, matching starts from the beginning of the string.

​
Example

local regex = RegexMatcher.new("strcpy|strcat|sprintf")
if regex:is_match(function_name) then
  -- Function name matches the pattern
end

-- Check if text matches starting from position 5
if regex:is_match(text, 5) then
  -- Pattern matches from position 5 onwards
end
