Quick Start

local
    rx: SIMPLE_REGEX_QUICK
    words: ARRAYED_LIST [STRING]
do
    create rx.make

    -- Check if pattern matches
    if rx.matches ("[a-z]+", "hello") then ...

    -- Find first match
    if attached rx.find ("\w+", "Hello World") as word then
        print (word)  -- "Hello"
    end

    -- Find all matches
    words := rx.find_all ("\w+", "Hello World")  -- ["Hello", "World"]

    -- Replace first match
    print (rx.replace ("World", "Eiffel", "Hello World"))  -- "Hello Eiffel"

    -- Replace all matches
    print (rx.replace_all ("\d+", "X", "a1b2c3"))  -- "aXbXcX"

    -- Split by pattern
    words := rx.split ("\s+", "Hello   World")  -- ["Hello", "World"]

    -- Extract all emails/URLs/numbers from text

    numbers := rx.extract_numbers (document)

    -- Capture groups
