Flex :: Recognize Multiple Lexical Errors In An Input String?
Mar 15, 2011
I am using flex to generate a lexical analyser for a custom language. The problem I am having is that as soon as I find a misformed token... I have no way to tell what other tokens follow this one. e.g.[code]Here, the stream of tokens will be id,<,>,id,<;>...... the language specifies that each token be seperated by a whitespace. So seeing a v after 1 should produce an error and the scanner has to print that error. After that, there are more legal tokens and another illegal token (~return). How do I process the rest of the legal tokens and print the second error.I am using flex as the scanner generator. When I find that none of the regular expressions for the lexeme matches, I call an error routine that prints the appropriate message.How do I resume processing after calling this routine?

I was wondering. Is there any lexical/syntax analizer (like Flex/Bison) that would work on Android? In this case it would be something like JavaCC, considering the Android SDK uses Java.
So far I have only found out that ANTLR could work on Android. Are there any other options you know of?

If I load an SWF with a query string at the end, like:
object.swf?this=that
then "this" is properly recognized as a flashvar within the flash object.But, if I set "this" via mod_rewrite, as in:
RewriteRule ^object$ lib/object.swf?this=that [QSA,NC,L]
then "this" is undefined.I even wrote a little PHP script to dump the contents of $_GET (changed the rewrite target temporarily), and I'm positive that the rewrite rule is working.
mod_rewrite clarification:
To demonstrate the strangeness of the problem, let me temporarily change the rewrite target to "object.php", so the rule now reads:
RewriteRule ^object$ lib/object.php?this=that [QSA,NC,L]
I created object.php in the /lib/ directory with the following line:
<?php echo '<pre>'.print_r($_GET, true).'</pre>'; ?>
Then, when I navigate to /object, I get the following output:
Array
(
[this] => that
)
This demonstrates that the rewrite rule is working as expected.Still, when I change the rewrite target back to the SWF, "this" is not recognized as a flashvar.(I'd definitely check the rewrite log to make sure, but I don't think I have access to it on the Media Temple server I'm using.)

One of our application is implemented in flex and adobe air. We want to have the user press combination of keys, say 'ABC', and have the keyboard return a different character, 'FOG', to whatever app is in focus. This should work even if app has no focus.
Will it possible in Adobe Air/Flex? If yes, provide me some examples?

I'm trying to create a form that based on the users input would determine how many forms to generate dynamically. I have a base state with a combo box that contains 1-4. Bases on the users selection I would like to have the next state generate the number of forms. So if you user selects 2 and click next - 2 copies of the form would be display.
I'm just wondering if this is possible how i would go about doing this or if any one knows of any examples?

I'm using AS3 in timeline. I have a three page movieclip (dynamic_mc). Each page is labeled p1..p3. On p1 I have an input text box named userName and button named next_1. On p2 I have a dynamic text box named greetings_1, an input text field named schoolName and two buttons (back1 and next2).On p3 I have another dynamic text box named greetings_2 and two buttons (back_2 and next_3).
On p1 user enters name, which is captured on p2. Once a click next button on p1, I get this error:
TypeError: Error #1009: Cannot access a property or method of a null object reference. at FlashCS4_Curriculum_fla::lesson9_pg6_dynamic_122/frame10() at flash.display::MovieClip/gotoAndStop() at FlashCS4_Curriculum_fla::lesson9_pg6_dynamic_122/goP2()
Why do I get an error when using buttons? Is there a better way to capture input text?
Here is the code by page.
//page 1 = p1stop();
var hisName:String;
next_1.addEventListener(MouseEvent.CLICK, goP2);function goP2(evt:MouseEvent): void{ hisName =userName.text; gotoAndStop("p2");
} // page 2 =p2 greetings_1.text= "Welcome :" +hisName;var school:String;
//next buttonnext_2.addEventListener(MouseEvent.CLICK, goP3);

In Actionscript and Adobe Flex, I'm using a pattern and regexp (with the global flag) with the string.match method and it works how I'd like except when the match returns multiple occurrences of the same word in the text. In that case, all the matches for that word point only to the index for the first occurrence of that word. For example, if the text is "cat dog cat cat cow" and the pattern is a search for cat*, the match method returns an array of three occurrences of "cat", however, they all point to only the index of the first occurrence of cat when i use indexOf on a loop through the array. I'm assuming this is just how the string.match method is. I want to find the specific indices of every occurrence of a match, even if it is of a word that was already previously matched.

I've found out that when publishing with Flash 8 my previous MX's working fla files, I get multiple errors.I've had a look at the Export publishing settings and I think they're all correct: - Exporting version: 8- AS Version: 1.0So, I guess it must be a silly thing I'm doing wrong but after a long while I haven't been able to know what's wrong. Perhaps AS compatibility is not that accurate?The most common error I get is:"A ')' or ',' was expected" or"An unexpected '}' was found"(I'm using Spanish Flash 8, so I don't know if this is the exact message you're given in English Flash 8) The 'supposed to be wrong' code seems to be in lines like[AS].posicion = posicion+eval("abc" add i)+gap;abc=eval("_parent._parent.abc" add _parent.n)[/AS]and I even get a "Declaration must be inside a on/onClipEvent controller" here:[AS]._xscale=abc*1.4;[/AS] ...while ALL of this code worked perfectly in Flash MX, I get up to 104 errors in Flash 8

[Code]...
Do you have idea about the reason for that error and how to prevent it? N.B. The code that triggers this error is as a result for click handler. If before encountering this error change the selection on my yearsCb, everithing is fine. EDIT: I forget to specify that this error is thrown when it is a selected item in my ComboBox. It seem that after container that holds the ComboBox loses the focus, it doesn't recognize it's ComboBox child as having a selected item anyway (this problem arise only after the modal popup close.).

I do math applications for the web. Often I have to check if a user input is correct. For example: the right answer is 3x+5. Is the user input that.I do this by checking character by character. I don't think that it is the best way, especially since the user may have written 5+3x, which is right, too, although it is preferred to write the other way around.I sometimes have to check more complicated expressions, like -3x^2+7x-15 or -2 sin (4x^2).Right now I'm doing an equation solving exercise. There I have to check what the user wants to do to the equation, like +2x or /(-5).

IŽam trying to create my own custom list component in a Flex mobile Project which fires an Event when the user touches a listitem and holds the finger down for a given time.Some kind of "longTouch"-Event like its implemented on native android listitems to edit the entry for example.
I tried to listen for the MOUSE_DOWN Event to start a timer and dispatch an event when the timer finished. But this approach failed because i cant get the listitem that was pressed by the user because the List component updates the "selectedItem"-property only after the user lifts his finger from the list.
