Harnocode

Reformats JavaScript code to look like an ASCII-art picture of your choice. Like this:

                   const                          esprima   =
               require('esprima');            const   escodegen =
             require( 'escodegen') ;        const fs=require('fs');
           exports.harnocode=function(    code,mask,options){options=
          options||{ };const  format= {  safeConcatenation  :  true  ,
         escapeless:true,semicolons:true,renumber:true,quotes:'single'}
         ;code=escodegen.generate(esprima.parse(code),{format:format});
         const tokens=tokenize(code);const lines=splitMaskToGroups(mask
         );let  tokenIndex= 0; let groupIndex =0; let result =[ ];let
         splitStrings=options. splitStrings===undefined?false: options.
          splitStrings;let safe=options.safe===undefined?true:options.
           safe;function processMask(){return lines.map(groups=>{let
             lineResult=[ ];let  offset= 0;if( tokenIndex>=tokens .
              length)return ;groups .forEach (( group,i )=> {let
                groupWidth=group[0].length;let isBeforeNewline=i
                  ==groups.length -1;if( group.index<offset ){
                    groupWidth -= offset- group .index ; if(
                      groupWidth <= 0  ) return ; }  let
                        groupTokens=takeTokens (tokens ,
                          groupWidth , tokenIndex  , {
                            isBeforeNewline , safe ,
                              splitStrings}); let
                                groupTokensJustified
                                  = justify  (
                                    groupTokens
                                         ,

The code should stay functional after the transformation.

"Harnocode" (ukr. гарнокод) means "beautiful code" in the Ukrainian language.
