Extension to use an external scripting language, Lua.

Since an infinite loop can be achieved by Lua, script_monitoring.sh run by crond will kill all Lua processes running longer than 10 seconds.

For security, Lua's io, debug, package, os library are nullified. Also, the program halts when it finds 'dofile'.

Example

{{#lua:luaコード|標準入力}}

第一引数にコード、第二引数に標準入力文字列を渡します。第二引数はコード中で「stdin」として利用できます。

• ソース

{{#lua:print(stdin)|input string}}

• 実行例

input string

Requirements

• lua
