linux - How can I direct output from a program to fill a form on a webpage? -

-

my 1d barcode scanner appears input device in linux allowing me fill web page form barcode scans if manually typing input. need replicate 'scan--put data web form' behaviour using 2d barcodes read webcam , extracted command line utility. utility i'm using (zbarcam), prints detected code stdout whenever barcode detected---very nice! need somehow redirect stdout stream current web page in browser can fill in text box data. seems simple redirection problem can't figure out how make work. perhaps there way make utility act 'virtual' input device?

i go way.

first send output of app temp location, file automatically updated everytime read new barcode.

zbarcam <params> > /tmp/barcodeoutput

then create script 1 automatically using ajax , jquery refresh contents.

index.php

<html> <head>     <title>jquery ajax</title>      <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.6.2/jquery.min.js"></script>     <script type="text/javascript">  $(document).ready(function() {      $("#content").load("feed.php");    var refreshid = setinterval(function() {       $("#content").load('feed.php?randval='+ math.random());    }, 2000);    $.ajaxsetup({ cache: false }); }); </script> </head> <body>      <pre id="content">      </pre>  </body> </html>

and last file php file index.php call using ajax.

feed.php

<?php readfile('/tmp/barcodeoutput');   ?>

-
i got following problem: i have object called tempscore game. this object blitted canvas renderer via copypixels method. object not display object. it's score-object (self made). score-object extends object called basicblitarrayobject. basicblitarrayobject extends eventdispatcher (therefore no display object). i tried apply several different tweenlite-plugins tempscore-object (i.e. transformaroundcenter, colormatrixfilter, etc.). nothing happens. absolutely nothing. sometimes error messages (when plugin requires display object , object not display object). far good. according greensock (maker of tweenlite) engine can tween numeric property of object. when plugin transformaroundcenter requires display object tweening have modify plugin working non-display object (tempscore). can't because it's way hard me. my game rests upon code: http://www.8bitrocket.com/book/ch11_blastermines.zip try apply tweenlite object called tempmine inside game class blastermines.
