The macro to generate template with SCF

macrosTemp.tmpl

#? stdtmpl | standard
# view(
# for i in 0..12:
  # if true == true:
  <h1>hello world $i</h1>
  # end if
# end for
# )

main.nim

include "viewMacro.nim"
include "macrosTemp.tmpl"

echo pastes_index_view()

viewMacro.nim

import macros

macro view*(x: untyped): untyped =
  quote:
    template pastes_index_view*(): untyped =
      var result {.inject.} = ""
      `x`
      result

First working version of creating template using macro within SCF file.
Note the two extra spaces before result.add is essential to make indentation correct.

#? stdtmpl(emit="  result.add") | standard

You can actually use view(code) syntax
