  Julia syntax highlighting file for the KDE editors Kate and Kwrite
  ====================================================================

  This was adapted from the Matlab syntax highlighting file

  Most of this XML file is straightforward. Only the character ' (&apos;)
  needs nontrivial treatment, since it is both a postfix operator indicating
  complex conjugate transpose (adjoint) and a character delimiter. It is an
  adjoint operator in the following positions:
  1) immediately after an identifier (variable, function, but not keyword)
  2) immediately after a number literal
  3) immediately after the closing parenthesis ), ] and }
  4) immediately after a simple transpose operator .'
  5) immediately after another adjoint operator '
  Otherwise it is a character delimiter.

  This is implemented using look-ahead regexps. If one of the entities in the
  above cases 1-4 (identifier, number literal, ...) matches and look-ahead
  shows that it is followed by a ', the entity is highlighted and control is
  passed to the special context _adjoint, whose sole purpose is to correctly
  highlight a series of ' (thus covering case 5 as well). _adjoint immediately
  returns to the default context _normal.
