escaping double quotes in strings

[Brydon Cheyney <br...@2fluid.co.uk>]

hi,

according to the user guide, if the right hand side of a #set directive, is
a string literal, strings quoted by "..." are interpolated, while strings
quoted by '...' are not.   this allows you to set variables such as

#set ( $foo = "$bar$baz" )

however, what this does /not/ allow you to do it seems is this

#set ($foo = "foo=\"$bar\"" )

which you would imagine would be valid code.  after all, you can quote other
characters within the string literal, so why not double quotes?

or am i missing something?  i'd search the archives on mail-archive, but it
appears the facility is broken.

cheers,
brydon

Do you mean escape?  - you can't escape characters in Velocity.

No, not broken.

In 1.4, there is an existing proposal for doing

  #set($foo = " This is ""quoted""!")
  #set($foo = ' This is ''quoted''!')

because it's backwards compatible.
