Jump to navigationJump to searchTemplate:Module rating This module implements Template:Coxeter–Dynkin diagram. It is invoked as
{{#invoke:Coxeter–Dynkin diagram|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.
<syntaxhighlight lang="lua"> local CDD = require('Module:Coxeter–Dynkin diagram')._CDD </syntaxhighlight>
You can then use it with the following syntax.
<syntaxhighlight lang="lua"> CDD{"node", "3", "node"} </syntaxhighlight>
See the template documentation for possible inputs.
