Subscripts in Haskell Diagrams
Posted on March 31, 2014
Not sure what the official way of doing subscripts in Diagrams is, but surprisingly this tiny piece of code does the job:
subs :: String -> String -> Diagram B R2 subs x y = norm ||| strutX (0.05) ||| sub where norm = stroke $ textSVG x 1 sub = stroke $ textSVG y 1 # translateY (-0.35) # scale 0.55
subs "Unicode: X₈ / Haskell: X" "8"
Why not just use the unicode subscripts? Simple: not all subscript characters are defined in the unicode.
