ASCII Rune

ASCII runes are an important component of the hoon programming language. They replace the awkward practice of using keywords.

Two glyphs make a digraph. For instance +: is a digraph pronounced as lus-col.

This is the decrement function written in hoon.

++  dec
      ~/  %dec
      |=  a=@
      ^-  @
      ?<  =(0 a)
      =+  b=@
      |-
      ?:  =(a +(b))
        b
      $(b +(b))

When translated, this becomes "luslus dec sigfas cen dec bartis a tis pat sigbar soq dec soq ketcab pat wutgal tis pel zero a per tislus b tis pat barhep wutcol tis pel a lus pel b per per b buc pel b lus pel b per per", which is far simpler.
