# Test script for Tkhtml
#
# This file contains test cases that ensure the handling of syntax
# errors in stylesheets is consistent with other interpretations of
# the various CSS specs.
#
# Interfaces:
#
#     pathName style TEXT
#     pathName parse -final TEXT
#     pathName search SELECTOR
#     nodeHandle property PROPERTY-NAME
#

# Standard test file code.
proc sourcefile {file} {
  set fname [file join [file dirname [info script]] $file] 
  uplevel #0 [list source $fname]
}

  .h reset
  .h parse -final $a(-document)
  .h style $a(-style)
  tcltest::test $name {} -body $a(-body) -result $a(-result)
}

#---------------------------------------------------------------------
# The following tests - syntax-1.* - come from the selectors 
# in the acid2 page.
#
syntaxtest syntax-1.0 -style {
  div { 
    background: yellow /* comment */ no-repeat /* comment */ ; 
  }
} -document {
  <div></div>
} -body {
  set node [lindex [.h search div] 0]
  $node property background-color
} -result yellow

} -body {

  $node property position
} -result absolute

#---------------------------------------------------------------------
# The selector in this test case - syntax-2.0 - comes from 
# "http://www.freenigma.com". This should just be handled as a 
# syntax error (ignore the whole declaration):
#
#   a:* {
#     text-decoration: none;
#     color: #436976;
#   }
#

  }
} -document {
  <a>Hello</a>
} -body {
  set node [lindex [.h search a] 0]
  $node property color
} -result black
#
# Also from www.freenigma.com:
#
#   @CHARSET "UTF-8";
#
#   div.content h1 { color: red }
#

#---------------------------------------------------------------------
# The selector in this test case - syntax-3.0 - tests a problem found at
# "http://www.yahoo.com". The lines prefixed with "*" should be skipped,
# the others respected.
#
# Apparently people have figured out that the following are all legal
# ways of commenting out a property/value pair in CSS:
#
#     selector {
#       *prop: value;
#       # prop: value;
#       // prop: value;
#     }
#

    text-decoration:underline;
    *color:red;
    color:green;
    *text-decoration:strikethrough;
  }
} -document {
  <div>Hello</div>
} -body {
  set node [lindex [.h search div] 0]
  list [$node property color] [$node property text-decoration]
} -result {green underline}
syntaxtest syntax-3.1 -style {
  div {
    text-decoration:underline;
    // color:red;
    color:green;
    # text-decoration:strikethrough;
  }
} -document {
  <div>Hello</div>
} -body {
  set node [lindex [.h search div] 0]
  list [$node property color] [$node property text-decoration]
} -result {green underline}
#---------------------------------------------------------------------
