模块:CDD/sandbox

![]() | 这是Module:CDD(差异)的沙盒。 |
本模组是为了要实现考克斯特计号显示用的{{CDD}}模板,即Template:CDD的显示所建立的。原始版本之支援最多50个记号,现在则可以引用超过50个记号。
使用方法:
{{#invoke:CDD|CDD}}
though the parameter is ignored; instead it uses the parameters passed to the template. See the template documentation for how that is used.
For using this from other Lua modules, first load the module.
local CDD = require('Module:CDD')._CDD
You can then use it with the following syntax.
CDD{"node", "3", "node"}
See the template documentation for possible inputs.
