Monitor global variable from AngularJS -


i want monitor value of global variable angular. have flash movie records microphone data , pushes out global variable. reference variable angular this:

$scope.audiodata = $window.audiodata; $scope.$watch('audiodata', function() {     console.log("audio in angular!:", $scope.audiodata.length); });

and in html i've put:

<h1>{{audiodata.length}}</h1>

in html can see audio data changed after recorded, watch function not being called while it's recording, need stream audio server.

there 2 things keep in mind here.

the first $watch default watches identity of objects , array, doesn't notice if there changes inside value. can solved watching length or using third argument yoshi has mentioned.

the second thing remember angular check watches when triggers it. if nothing happening in angular-world, no watches or callbacks executed. since recorder lives outside of angular-world, needs notify angular has been changed. can done calling $apply after updating recording. alternate way consider have angular update @ regular intervals using $timeout.

linux - Does gcc have any options to add version info in ELF binary file? -

i mean whether gcc can insert source code version infor elf binary section or similar. not want change source file, add info gcc option in makefile. you can emit version info text file, turn text file object file statically link executable. the first step simple have write code: script or write version info in format plain text file. write makefile rule produce version.o version.txt, using objcopy . you'll have object file 2 useful symbols defined in it: beginning , end of textual version info. add generated object executable, , you'll able access version 2 ways: running strings on binary, or writing code in application print version string (you'll need declare start , end symbols variables in header file).
