命名跟修改一个string:
a = "one string" b = string.gsub(a, "one", "another") -- change string parts print(a) --> one string print(b) --> another string
转义字符:
\a bell
\b back space
\f form feed
\n newline
\r carriage return
\t horizontal tab
\v vertical tab
\\ backslash
\" double quote
\‘ single quote
\[ left square bracket
\] right square bracket
不想累死的话, 用[[]]包含大量的转义字符:
page = [[
<HTML>
<HEAD>
<TITLE>An HTML Page</TITLE>
</HEAD>
<BODY>
<A HREF="http://www.lua.org">Lua</A>
[[a text between double brackets]]
</BODY>
</HTML>
