Lua實現*

Question

如何在Lua中實現vba-like符號*？ 我想在字符串"aaabbb"（false）或"aabbds"（true）中比較"aabb*"這樣的模式。

Answer 1

function string.like(text, pattern) 
    pattern = "^"..pattern:gsub("*", "\0"):gsub("%p", "%%%0"):gsub("%z", ".-").."$" 
    return text:find(pattern) and true or false 
end 

用法是local bool_result = str:like(pattern)

local pattern = "aabb*" 

print(("aaabbb"):like(pattern)) --> false 
print(("aabbds"):like(pattern)) --> true
