Example 36 with Varargs

use of org.luaj.vm2.Varargs in project LuaViewSDK by alibaba.

the class StringLib method gsub.

/**
 * string.gsub (s, pattern, repl [, n])
 * Returns a copy of s in which all (or the first n, if given) occurrences of the
 * pattern have been replaced by a replacement string specified by repl, which
 * may be a string, a table, or a function. gsub also returns, as its second value,
 * the total number of matches that occurred.
 *
 * If repl is a string, then its value is used for replacement.
 * The character % works as an escape character: any sequence in repl of the form %n,
 * with n between 1 and 9, stands for the value of the n-th captured substring (see below).
 * The sequence %0 stands for the whole match. The sequence %% stands for a single %.
 *
 * If repl is a table, then the table is queried for every match, using the first capture
 * as the key; if the pattern specifies no captures, then the whole match is used as the key.
 *
 * If repl is a function, then this function is called every time a match occurs,
 * with all captured substrings passed as arguments, in order; if the pattern specifies
 * no captures, then the whole match is passed as a sole argument.
 *
 * If the value returned by the table query or by the function call is a string or a number,
 * then it is used as the replacement string; otherwise, if it is false or nil,
 * then there is no replacement (that is, the original match is kept in the string).
 *
 * Here are some examples:
 * 	     x = string.gsub("hello world", "(%w+)", "%1 %1")
 * 	     --> x="hello hello world world"
 *
 *	     x = string.gsub("hello world", "%w+", "%0 %0", 1)
 *	     --> x="hello hello world"
 *
 *	     x = string.gsub("hello world from Lua", "(%w+)%s*(%w+)", "%2 %1")
 *	     --> x="world hello Lua from"
 *
 *	     x = string.gsub("home = $HOME, user = $USER", "%$(%w+)", os.getenv)
 *	     --> x="home = /home/roberto, user = roberto"
 *
 *	     x = string.gsub("4+5 = $return 4+5$", "%$(.-)%$", function (s)
 *	           return loadstring(s)()
 *       end)
 *	     --> x="4+5 = 9"
 *
 *	     local t = {name="lua", version="5.1"}
 *	     x = string.gsub("$name-$version.tar.gz", "%$(%w+)", t)
 *	     --> x="lua-5.1.tar.gz"
