Ok probably barking up the wrong tree with this one but some guidance would be nice!
Currently got an app that exports data to a text file
stream.open(file, FileMode.APPEND);
stream.writeUTFBytes(data1 + data2);
stream.close();
and then use the following to import that data
var textloader:URLLoader = URLLoader(event.target);
MyTextFile_txt.text = textloader.data;
Now is there anyway of sorting this information (for example put it in order of data2 records)? I know sorting from a textfile is probably a little difficult. Would there be a better way of exporting the file instead? Or when importing the file can I get it to import into a specific text box.
Dunno just throwing some ideas out.
Although not essential you can use stream.readUTFBytes instead of URLLoader.
Regarding sorting data you can add all the loaded data into an array and then use sort() on the array.
e.g.
var someArray:Array = [];
for (var i:int; i < loadedData.xmlNodeName.length; i++) {
someArray.push(loadedData.xmlNodeName[i]);
}
someArray.sort();

I have been searching for ar.js multimarkers tutorial or anything that explains about it. But all I can find is 2 examples, but no tutorials or explanations.
So far, I understand that it requires to learn the pattern or order of the markers, then it stores it in localStorage. This data is used later to display the image.
What I don't understand, is how this "learner" is implemented. Also, the learning process is only used once by the "creator", right? The output file should be stored and then served later when needed, not created from scratch at each person's phone or computer.
Any help is appreciated.
Since the question is mostly about the learner page, I'll try to break it down as much as i can:
1) You need to have an array of {type, URL} objects.
A sample of creating the default array is shown below (source code):
var markersControlsParameters = [
{
type : 'pattern',
patternUrl : 'examples/marker-training/examples/pattern-files/pattern-hiro.patt',
},
{
type : 'pattern',
patternUrl : 'examples/marker-training/examples/pattern-files/pattern-kanji.patt',
}]
2) You need to feed this to the 'learner' object.
By default the above object is being encoded into the url (source) and then decoded by the learner site. What is important, happens on the site:
for each object in the array, an ArMarkerControls object is created and stored:
// array.forEach(function(markerParams){
var markerRoot = new THREE.Group()
scene.add(markerRoot)
// create markerControls for our markerRoot
var markerControls = new THREEx.ArMarkerControls(arToolkitContext, markerRoot, markerParams)
subMarkersControls.push(markerControls)
The subMarkersControls is used to create the object used to do the learning. At long last:
var multiMarkerLearning = new THREEx.ArMultiMakersLearning(arToolkitContext, subMarkersControls)
The example learner site has multiple utility functions, but as far as i know, the most important here are the ArMultiMakersLearning members which can be used in the following order (or any other):
// this method resets previously collected statistics
multiMarkerLearning.resetStats()
// this member flag enables data collection
multiMarkerLearning.enabled = true
// this member flag stops data collection
multiMarkerLearning.enabled = false
// To obtain the 'learned' data, simply call .toJSON()
var jsonString = multiMarkerLearning.toJSON()
Thats all. If you store the jsonString as
localStorage.setItem('ARjsMultiMarkerFile', jsonString);
then it will be used as the default multimarker file later on. If you want a custom name or more areas - then you'll have to modify the name in the source code.
3) 2.1.4 debugUI
It seems that the debug UI is broken - the UI buttons do exist but are nowhere to be seen. A hot fix would be using the 'markersAreaEnabled' span style for the div
containing the buttons (see this source bit).
It's all in this glitch, you can find it under the phrase 'CHANGES HERE' in the arjs code.
Using JavaScript for automation in macOS, it's straightforward to get the elements of a container. But I can't figure out how to get the containers of an element.
In the Photos documentation, for example, an Album "contains mediaItems"; and a MediaItem is "contained by albums".
This works:
Application('Photos').albums[0].mediaItems()
This is what I want to write, but does not work:
Application('Photos').mediaItems[0].albums()
(resulting error:
Error: Can't get object. (-1728)
)
I've also tried to do something with the whose method, but I'm not quite sure how to write it:
Application('Photos').albums.whose({ /* what to put here? */ })
(Obviously I'd rather use the more direct route, if it exists, but if the proper way to do what I want is via whose, okay.)
I don’t think there’s a direct answer to this question. What you’re basically looking for, if I read you correctly, is, how can I use JXA to query a container based on its elements. That is, you want the answer to how to perform this AppleScript query in JavaScript:
tell application "Photos"
--get an arbitrary photo
set firstPhoto to the first media item
--get the albums that contain that photo
get the name of every album whose id of media items contains id of firstPhoto
end tell
This means going multiple levels deep, something like:
//this does not work
var firstPhoto = Application('Photos').mediaItems[0]();
var containingAlbums = Application('Photos').albums.whose({mediaItems: {_contains: firstPhoto}});
But according to the error this script generates, the albums object doesn’t even have a property called “mediaItems”.
Tantalizingly, if you were to run the following script you would see the ids of each of the albums that contains your photo:
//get a photo
var firstPhoto = Application('Photos').mediaItems[0]();
var firstPhotoId = firstPhoto.id();
albumQuery = Application('Photos').albums.mediaItems.where({id: {_equals: firstPhotoId}});
containingAlbums = []
for (var possibleAlbum of albumQuery[0]()) {
if (possibleAlbum != null) {
containingAlbums.push(possibleAlbum);
}
}
containingAlbums;
I see, for example,:
[Application("Photos").albums.byId("RLf9PUOxSLunpY5vFLLR6A").mediaItems.byId("68IM5jaiRDqIJhcKVBXo%w"),
Application("Photos").albums.byId("7QpA6wQrSEeIPyhu8xHlOw").mediaItems.byId("68IM5jaiRDqIJhcKVBXo%w"),
Application("Photos").albums.byId("SX8PbxO9S+a4%w4FvHH%Og").mediaItems.byId("68IM5jaiRDqIJhcKVBXo%w")]
But if I change the push line to containingAlbums.push(possibleAlbum.properties()); I see no property that will get the album name or even id back in any of the entries.
I asked a similar question about getting people from the same city in Contacts. The only solution I’ve been able to find is to get your media item and then loop through all albums.
//get an arbitrary photo
var firstPhoto = Application('Photos').mediaItems[0]();
var firstPhotoId = firstPhoto.id();
//loop through all albums and compile list of those that contain this photo
var containingAlbums = []
for (var possibleAlbum of Application('Photos').albums()) {
if (possibleAlbum.mediaItems.whose({id: {_equals: firstPhotoId}}).length) {
containingAlbums.push(possibleAlbum.name());
}
}
containingAlbums;
This is obviously not a satisfactory answer. I’m providing it in the hope that it may help you hack up a solution, and that someone will put up a better answer to prove me wrong.
In general, JXA support is spotty enough that if you don’t need one of its features that AppleScript doesn’t have, such as the ability to chain queries programmatically, it’s better to build the solution in AppleScript.
I'm a beginning learner of InDesign scripting and would like to help myself with debugging, but my attempts seem to run into walls. Hope someone has some insights that will help me going forward.
I'm working on a little project that loops through some selected tables, puts the 3 tables into an array/variable (accomplished that) and then loops through the content of those tables to find a GREP match and store those in an array/variable (for further uses I won't get into now)
My main objective at this point: See exactly what text characters the .findGrep(); function is catching and display those in the Javascript Console of the ExtendScript Toolkit app.
So here's a bit of the journey up to this point, including codes tried and suggestions from others. (All of my attempted uses of these has failed...why I'm here now... and why this is long; my apologies)
Initial try.
var myTables = []; (in Data Browser this shows values of [object Table], [object Table], [object Table]
var myFinds = [];
var myTest = [];
var myCharacters = [];
app.findGrepPreferences = null;
app.findGrepPreferences.findWhat = "\"";
for (x = 0; x < myTables.length; x++) {
var myFinds = myTables[x].findGrep();
$.writeln(myFinds);
};
Notes on this code: Because not every table has the characters in the findWhat, sometimes in this loop myFinds has nothing, but when it does have something, it shows this in console [object Character],[object Character],[object Character]
So someone (firstHelp) gave me this: And it did not work... error thrown on .contents.toString(); *"undefined is not an object" which I thought, "ok, yes I see at times in the loop myFinds has nothing in it... more on this later"
var stringArray = [];
for( var n=0; n<myFinds.length; n++ ) {
stringArray[n] = myFinds[n].contents.toString();
};
$.writeln(myFinds.join("\r"));
Code revamp Gave up on the $.writeln(myFinds); within the loop and tried this in order to gather Grep finds in a variable/array that could be dealt with outside of loop.
for (x = 0; x < myTables.length; x++) {
$.writeln(myTables[x].cells.firstItem().texts[0].contents[0]);
myFinds.push(myTables[x].findGrep());
};
$.writeln(myFinds);
ExtendScript Toolkit console now showing this for myFinds:
*myFinds = [Array], [object Character], [object Character], [object...
+ (object symbol) 0 =
+ (object symbol) 1 = [object Character], [object Character], [object Character]
+ (object symbol) 2 =
+ (object symbol) _proto_ =*
*again tried the .contents.toString(); on the myFinds and still the same error, "undefined..." including targeting the array when it clearly had something in it.
**So then I get this tipoff...(but no helpful code to apply to what I already have)
"you are dealing with arrays of arrays mixed with texts.
So you have to check with each item of the result array if it is text
or another array of texts.
If it is an array loop that array."
And later this bit of code that is supposed to "flatten" my array... a = [].concat.apply([],a);
Replacing a with myFinds like this, myFinds = [].concat.apply([],myFinds); did absolutely nothing. The array and its contents showed no change in the console... and I have no idea how to loop through each item of this array within an array, find out if it's text or another array and then show its real contents to console.
Really...how many loops and if/thens etc do I need to run on one array to show its actual contents in the console? But I know I struggle with breaking down every little step I want, to its minute scripting granularity and so my ignorance regularly impedes me. I welcome any suggestions/tips to move me closer to my **main objective" as stated above. Thanks
Regarding the first help. The real reason why you get an error while accessing content property is that you don’t check the type of the object and presume it will be a Text object. As the findGrep may not find a Text occurrence, you actually get an empty array. And Array.prototype.contents doesn’t exist hence the error.
Then $.writeln is legacy of Adobe ExtendScript toolkit, the IDE for ExtendScript. This product is no longer de eloped and maintained by Adobe. You should consider using other logging techniques such as the Visual Studio ExtendScript plugin which will allow you to use breakpoints and everything you need.
I'm having some trouble with reading out the IPTC data of some images, the reason why I want to do this, is because my client has all the keywords already in the IPTC data and doesn't want to re-enter them on the site.
So I created this simple script to read them out:
$size = getimagesize($image, $info);
if(isset($info['APP13'])) {
$iptc = iptcparse($info['APP13']);
print '<pre>';
var_dump($iptc['2#025']);
print '</pre>';
}
This works perfectly in most cases, but it's having trouble with some images.
Notice: Undefined index: 2#025
While I can clearly see the keywords in photoshop.
Are there any decent small libraries that could read the keywords in every image? Or am I doing something wrong here?
I've seen a lot of weird IPTC problems. Could be that you have 2 APP13 segments. I noticed that, for some reasons, some JPEGs have multiple IPTC blocks. It's possibly the problem with using several photo-editing programs or some manual file manipulation.
Could be that PHP is trying to read the empty APP13 or even embedded "thumbnail metadata".
Could be also problem with segments lenght - APP13 or 8BIM have lenght marker bytes that might have wrong values.
Try HEX editor and check the file "manually".
I have found that IPTC is almost always embedded as xml using the XMP format, and is often not in the APP13 slot. You can sometimes get the IPTC info by using iptcparse($info['APP1']), but the most reliable way to get it without a third party library is to simply search through the image file from the relevant xml string (I got this from another answer, but I haven't been able to find it, otherwise I would link!):
The xml for the keywords always has the form "<dc:subject>...<rdf:Seq><rdf:li>Keyword 1</rdf:li><rdf:li>Keyword 2</rdf:li>...<rdf:li>Keyword N</rdf:li></rdf:Seq>...</dc:subject>"
So you can just get the file as a string using file_get_contents(get_attached_file($attachment_id)), use strpos() to find each opening (<rdf:li>) and closing (</rdf:li>) XML tag, and grab the keyword between them using substr().
The following snippet works for all jpegs I have tested it on. It will fill the array $keys with IPTC tags taken from an image on wordpress with id $attachment_id:
$content = file_get_contents(get_attached_file($attachment_id));
// Look for xmp data: xml tag "dc:subject" is where keywords are stored
$xmp_data_start = strpos($content, '<dc:subject>') + 12;
// Only proceed if able to find dc:subject tag
if ($xmp_data_start != FALSE) {
$xmp_data_end = strpos($content, '</dc:subject>');
$xmp_data_length = $xmp_data_end - $xmp_data_start;
$xmp_data = substr($content, $xmp_data_start, $xmp_data_length);
// Look for tag "rdf:Seq" where individual keywords are listed
$key_data_start = strpos($xmp_data, '<rdf:Seq>') + 9;
// Only proceed if able to find rdf:Seq tag
if ($key_data_start != FALSE) {
$key_data_end = strpos($xmp_data, '</rdf:Seq>');
$key_data_length = $key_data_end - $key_data_start;
$key_data = substr($xmp_data, $key_data_start, $key_data_length);
// $ctr will track position of each <rdf:li> tag, starting with first
$ctr = strpos($key_data, '<rdf:li>');
// Initialize empty array to store keywords
$keys = Array();
// While loop stores each keyword and searches for next xml keyword tag
while($ctr != FALSE && $ctr < $key_data_length) {
// Skip past the tag to get the keyword itself
$key_begin = $ctr + 8;
// Keyword ends where closing tag begins
$key_end = strpos($key_data, '</rdf:li>', $key_begin);
// Make sure keyword has a closing tag
if ($key_end == FALSE) break;
// Make sure keyword is not too long (not sure what WP can handle)
$key_length = $key_end - $key_begin;
$key_length = (100 < $key_length ? 100 : $key_length);
// Add keyword to keyword array
array_push($keys, substr($key_data, $key_begin, $key_length));
// Find next keyword open tag
$ctr = strpos($key_data, '<rdf:li>', $key_end);
}
}
}
I have this implemented in a plugin to put IPTC keywords into WP's "Description" field, which you can find here.
ExifTool is very robust if you can shell out to that (from PHP it looks like?)
I've used "Google AJAX Transliteration API" and it's going well with me.
http://code.google.com/apis/ajaxlanguage/documentation/referenceTransliteration.html
Currently I've a project that I need all input fields in every page (input & textarea tags) to be transliteratable, while these input fields differs from page to page (dynamic).
As I know, I've to call makeTransliteratable(elementIds, opt_options) method in the API call to define which input fields to make transliteratable, and in my case here I can't predefine those fields manually. Is there a way to achieve this?
Thanks in advance
Rephrasing what you are asking for: you would like to collect together all the inputs on the page which match a certain criteria, and then pass them into an api.
A quick look at the API reference says that makeTransliteratable will accept an array of id strings or an array of elements. Since we don't know the ids of the elements before hand, we shall pass an array of elements.
So, how to get the array of elements?
I'll show you two ways: a hard way and an easy way.
First, to get all of the text areas, we can do that using the document.getElementsByTagName API:
var textareas = document.getElementsByTagName("textarea");
Getting the list of inputs is slightly harder, since we don't want to include checkboxes, radio buttons etc. We can distinguish them by their type attribute, so lets write a quick function to make that distinction:
function selectElementsWithTypeAttribute(elements, type)
{
var results = [];
for (var i = 0; i < elements.length; i++)
{
if (elements[i].getAttribute("type") == type)
{
results.push(elements[i]);
}
}
return results;
}
Now we can use this function to get the inputs, like this:
var inputs = document.getElementsByTagName("input")
var textInputs = selectElementsWithTypeAttribute(textInputs, "text");
Now that we have references to all of the text boxes, we can concatenate them into one array, and pass that to the api:
var allTextBoxes = [].concat(textareas).concat(textInputs);
makeTransliteratable(allTextBoxes, /* options here */);
So, this should all work, but we can make it easier with judicious use of library methods. If you were to download jQuery (google it), then you could write this more compact code instead:
var allTextBoxes = $("input[type='text'], textarea").toArray();
makeTransliteratable(allTextBoxes, /* options here */);
This uses a CSS selector to find all of the inputs with a type attribute of "text", and all textareas. There is a handy toArray method which puts all of the inputs into an array, ready to pass to makeTransliteratable.
I hope this helped,
