javascript - Create and use user functions in lesscss -

i have in html:

<script type="text/javascript">     less = {         env: "development", // or "production"         async: false,       // load imports async         fileasync: false,   // load imports async when in page under                             // file protocol         poll: 1000,         // when in watch mode, time in ms between polls         functions: {             returncenter: function (value, context) {                 return 'center';             }         },      // user functions, keyed name         dumplinenumbers: "comments", // or "mediaquery" or "all"         relativeurls: false,// whether adjust url's relative                             // if false, url's relative                             // entry less file         rootpath: ":/a.com/"// path add on start of every url                             //resource     }; </script> <script src="less.js" type="text/javascript"></script> 

so in functions, how can create , use functions in less file?

thanks , luck!

p.d. returncenter, doesn't work. or without parameters.

for reason should write function names in lowercase. should function return proper type.

try:

<script> less = {      env: "development",     functions: {          returncenter: function(context, value) {             return new(less.tree.anonymous)('center');         }     } }; </script> 

now can use following less code:

selector { property: returncenter();     } 

the preceding less code compile following css code:

selector { property: center;     } 

nb see: user defined functions lesscss?
