  63 ## Special directives, etc.
  64 color magenta "\\s *#\\s *"
  65
  66 ## String literals
  67 ## TODO: multiline backtick and doublequote string. (Unlikely possible at all with nano.)
  68 ### DoubleQuotedString
  69 color yellow ""(\\.|[^"])*""
  70
  71 ### WysiwygString
  72 color yellow (s) "r".*?""
  73 color yellow "`[^`]*`"
  74
  75 ### HexString
  76 color ,yellow "x"([[:space:]]*[[:xdigit:]][[:space:]]*[[:xdigit:]])*[[:space:]]*""
  77
  78 ### DelimitedString
  79 color yellow "q"\(.*\)""
  80 color yellow "q"\{.*\}""
  81 color yellow "q"\[.*\]""
  82 color yellow "q"<.*>""
  83 color yellow (s) "q"[^({[<"][^"]*$.*?^[^"]+""
  84 color yellow "q"([^({[<"]).*\1""
  85
  86 ### TokenString
  87 ### True token strings require nesting, so, again, they can't be implemented accurately here.
  88 ### At the same time, the intended purpose of token strings makes it questionable to highlight them as strings at all.
  89 ## color ,magenta (s) "q\{.*?\}"
  90
  91 ## Comments
  92 ## NB: true nested comments are impossible to implement with plain regex
  93 color brightblack "//.*"
  94 color brightblack (s) "/\*.*?\*/"
  95 color brightblack (s) "/\+.*?\+/"
  96
