varargs[untyped] in template

[jk49]

based on @Clonk 's answer, I have used SCF with dumpTree,

`users.nimf`
    
    
    #? stdtmpl | standard
    #proc generateType(class: string,
    #                      fields: openArray[string]): string =
    #  result = ""
    import macros
    dumpTree:
        type
            ${class}* = object
                #for field in items(fields):
                ${field}*: string
                #end for
    
    
    Run
    
    
    include "users.nimf"
    # writeFile("users.nim", generateType("Person", @["name", "job", "email"]))
    
    
    import macros
    
    macro writeFileAtCompileTime(filename: string, content: string): untyped =
      # This macro will generate code to write a file at compile time
      result = quote do:
        static:
          writeFile(`filename`, `content`)
    
    # Usage of the macro
    writeFileAtCompileTime("users.nim", generateType("Person", @["name", "job", 
"email"]))
    
    # Regular code continues here
    echo "File has been written at compile time"
    
    
    
    
    # dumpTree here
    include users
    
    
    Run

result:
    
    
    StmtList
      TypeSection
        TypeDef
          Postfix
            Ident "*"
            Ident "Person"
          Empty
          ObjectTy
            Empty
            Empty
            RecList
              IdentDefs
                Postfix
                  Ident "*"
                  Ident "name"
                Ident "string"
                Empty
              IdentDefs
                Postfix
                  Ident "*"
                  Ident "job"
                Ident "string"
                Empty
              IdentDefs
                Postfix
                  Ident "*"
                  Ident "email"
                Ident "string"
                Empty
    
    
    Run

just an idea, can we use scf and dumpTree results to autogenerate macros from 
scf?
