javascript - ThunderBird Event for Viewing a Message -


i'm trying modify message before displayed in main window in thunderbird. can't seem find 1) event triggered when new message opened/viewed 2) way modify displayed contents of message.

i believe need chrome://messenger/content/messenger.xul overlay, , can use listener such as:

window.addeventlistener( "some magic here", modify_message_handler, true );

but event is, unsure, along object (a message header?) , how can modify displayed.

so questions are:

  • do have correct overlay?
  • can done events? if not, how?
  • if so, event needed , object pass?

if want similar greasemonkey script run on every message, should:

  1. wait load event of window.
  2. retrieve message pane object document.getelementbyid("messagepane").
  3. bind handler message pane's domcontentloaded event, or similar events load depending on when want handler called. domcontentloaded give greasemonkey-style behavior.
  4. in event handler, event.originaltarget document corresponding displayed message. can apply usual dom modification techniques here.

for more details, see this example documentation.

c++ - Accessing inactive union member and undefined behavior? -

i under impression accessing union member other last 1 set ub, can't seem find solid reference (other answers claiming it's ub without support standard). so, undefined behavior? the confusion c explicitly permits type-punning through union, whereas c++ ( c++11 ) has no such permission. c11 6.5.2.3 structure , union members 95) if member used read contents of union object not same member last used store value in object, appropriate part of object representation of value reinterpreted object representation in new type described in 6.2.6 (a process called ‘‘type punning’’). might trap representation. the situation c++: c++11 9.5 unions [class.union] in union, @ 1 of non-static data members can active @ time, is, value of @ 1 of non-static data members can stored in union @ time. c++ later has language permitting use of unions containing struct s common initial sequences; doesn't permit type-punning. to determine whether union type-punning is allowe...

php - Get uncommon values from two or more arrays -

is there function in php give array of uncommon values 2 or more arrays? for example: $array1 = array( "green", "red", "blue"); $array2 = array( "green", "yellow", "red"); .... $result = function_needed($array1, $array2,...); print_r($result); should give output: array("blue", "yellow", ...); use array_diff , array_merge : $result = array_merge(array_diff($array1, $array2), array_diff($array2, $array1)); here's demo. for multiple arrays, combine callback , array_reduce : function unique(&$a, $b) { return $a ? array_merge(array_diff($a, $b), array_diff($b, $a)) : $b; } $arrays = array( array('green', 'red', 'blue'), array('green', 'yellow', 'red') ); $result = array_reduce($arrays, 'unique'); and here's demo of that.
