  • How to handle HTML Strings in Cocoa Touch

    - by balexandre
    I'm using a RSS Reader and works fine when I tap the UITableViewCell to load the <link> either in a UIWebView or to open Safari on that link. But I really want to learn how to load the Topic content into the application instead showing the entire site or jump to Safari In the RSS feed per each <item> there is a <body> tag (and a <Description> that contains the same but encoded) that contains the topic content, like the image below shows: So, instead of catching the <link> I'm assigning the <body>. Problem is that it does not work correctly :-( for this example I only get the content until the first <br> nothing more. I'm using a NSString as I would use in C#, should I use any other object, is there a better object to use on such data? Should I use an UITextView to load this information (as it has scroll already) or I should use a UIWebView instead? Thank you.

  • scaling svg paths in Raphael 2.1

    - by user1229001
    I'm using SVG paths from a wikimedia commons map of the US. I've singled out Pennsylvania with its counties. I'm feeding the paths out of a database and using Raphael 2.1 to put them on the page. Because in the original map, Pennsylvania was so small and set at an angle, I'd like to scale up the paths and rotate Pa. so that it isn't on an angle. When I try to use Raphael's transform method, all the counties look strange and overlapped. I gave up on setting the viewBox when I heard that it doesn't work in all browsers. Anyone have any ideas? Here is my code: $(document).ready(function() { var $paths = []; //array of paths var $thisPath; //variable to hold whichever path we're drawing $.post('getmapdata.php', function(data){ var objData = jQuery.parseJSON(data); for (var i=0; i<objData.length; i++) { $paths.push(objData[i].path); //$counties.push(objData[i].name); }//end for drawMap($paths); }) function drawMap(data) { // var map = new Raphael(document.getElementById('map_div_id'),0, 0); var map = new Raphael(0, 0, 520, 320); //map.setViewBox(0,0,500,309, true); for (var i = 0; i < data.length; i++) { var thisPath = map.path(data[i]); thisPath.transform(s2); thisPath.attr({stroke:"#FFFFFF", fill:"#CBCBCB","stroke-width":"0.5"}); } //end cycling through i }//end drawMap });//end program

  • PHP get "Application Root" in Xampp on Windows correctly

    - by Michael Mao
    Hi all: I found this thread on StackOverflow about how to get the "Application Root" from inside my web app. However, most of the approaches suggested in that thread can hardly be applied to my Xampp on Windows. Say, I've got a "common.php" which stays inside my web app's app directory: / /app/common.php /protected/index.php In my common.php, what I've got is like this: define('DOCROOT', $_SERVER['DOCUMENT_ROOT']); define('ABSPATH', dirname(__FILE__)); define('COMMONSCRIPT', $_SERVER['PHP_SELF']); After I required the common.php inside the /protected/index.php, I found this: C:/xampp/htdocs //<== echo DOCROOT; C:\xampp\htdocs\comic\app //<== echo ABSPATH /comic/protected/index.php //<== echo COMMONSCRIPT So the most troublesome part is the path delimiters are not universal, plus, it seems all superglobals from the $_SERVER[] asso array, such as $_SERVER['PHP_SELF'], are relative to the "caller" script, not the "callee" script. It seems that I can only rely on dirname(__FILE__) to make sure this always returns an absolute path to the common.php file. I can certainly parse the returning values from DOCROOT and ABSPATH and then calculate the correct "application root". For instance, I can compare the parts after htdocs and substitute all backslashes with slashes to get a unix-like path I wonder is this the right way to handle this? What if I deploy my web app on a LAMP environment? would this environment-dependent approach bomb me out? I have used some PHP frameworks such as CakePHP and CodeIgniter, to be frank, They just work on either LAMP or WAMP, but I am not sure how they approached such a elegant solution. Many thanks in advance for all the hints and suggestions.

  • Isolated storage misunderstand

    - by Costa
    Hi this is a discussion between me and me to understand isolated storage issue. can you help me to convince me about isolated storage!! This is a code written in windows form app (reader) that read the isolated storage of another win form app (writer) which is signed. where is the security if the reader can read the writer's file, I thought only signed code can access the file! If all .Net applications born equal and have all permissions to access Isolated storage, where is the security then? If I can install and run Exe from isolated storage, why I don't install a virus and run it, I am trusted to access this area. but the virus or what ever will not be trusted to access the rest of file system, it only can access the memory, and this is dangerous enough. I cannot see any difference between using app data folder to save the state and using isolated storage except a long nasty path!! I want to try give low trust to Reader code and retest, but they said "Isolated storage is actually created for giving low trusted application the right to save its state". Reader code: private void button1_Click(object sender, EventArgs e) { String path = @"C:\Documents and Settings\All Users\Application Data\IsolatedStorage\efv5cmbz.ewt\2ehuny0c.qvv\StrongName.5v3airc2lkv0onfrhsm2h3uiio35oarw\AssemFiles\toto12\ABC.txt"; StreamReader reader = new StreamReader(path); var test = reader.ReadLine(); reader.Close(); } Writer: private void button1_Click(object sender, EventArgs e) { IsolatedStorageFile isolatedFile = IsolatedStorageFile.GetMachineStoreForAssembly(); isolatedFile.CreateDirectory("toto12"); IsolatedStorageFileStream isolatedStorage = new IsolatedStorageFileStream(@"toto12\ABC.txt", System.IO.FileMode.Create, isolatedFile); StreamWriter writer = new StreamWriter(isolatedStorage); writer.WriteLine("Ana 2akol we ashrab kai a3eesh wa akbora"); writer.Close(); writer.Dispose(); }

  • Problem with DataTrigger binding - setters are not being called

    - by aoven
    I have a Command bound to a Button in XAML. When executed, the command changes a property value on the underlying DataContext. I would like the button's Content to reflect the new value of the property. This works*: <Button Command="{x:Static Member=local:MyCommands.TestCommand}" Content="{Binding Path=TestProperty, Mode=OneWay}" /> But this doesn't: <Button Command="{x:Static Member=local:MyCommands.TestCommand}"> <Button.Style> <Style TargetType="{x:Type Button}"> <Style.Triggers> <DataTrigger Binding="{Binding Path=TestProperty, Mode=OneWay}" Value="True"> <DataTrigger.Setters> <Setter Property="Content" Value="Yes"/> </DataTrigger.Setters> </DataTrigger> <DataTrigger Binding="{Binding Path=TestProperty, Mode=OneWay}" Value="False"> <DataTrigger.Setters> <Setter Property="Content" Value="No"/> </DataTrigger.Setters> </DataTrigger> </Style.Triggers> </Style> </Button.Style> </Button> Why is that? * By "works" I mean the Content gets updated whenever I click the button. TIA

  • There is no attachment in the sent mail by iPhone

    - by naruhodo
    I'm trying to send a recorded sound file as attachment with MFMailComposeViewController. The sound file is OK. The picker shows the correct file name, shows the audio file icon as attachment, sends the mail, but there is no attachment in the result. I attached below the source of the sent mail.

  • Django Template tag, generating template block tag

    - by Issy
    Hi Guys, Currently a bit stuck, wondering if anyone can assist. I am using django-adminfiles. Which is a near little application. I want to use it to insert images into posts/articles/pages for a site i am building. How django-adminfiles works is it inserts a placeholder i.e <<< ImageFile and this gets rendered using a django template. It also has the feature of inserting custom options i.e (Insert Medium Image) , i figured i would used this to automatically resize images and include it in the post (similar to how WP does it). Django-adminfiles makes use of sorl.thumbnail app to generate thumbnails. So i have tried testing generating thumbnails: The current template that is used to render the inserted image is: {% spaceless %} <img src="{{ upload.upload.url }}" width="{{ upload.width }}" height="{{ upload.height }}" class="{{ options.class }}" class="{{ options.size }}" alt="{% if options.alt %}{{ options.alt }}{% else %}{{ upload.title }}{% endif %}" /> {% endspaceless %} I tried modifying this to: {% load thumbnail %} {% spaceless %} <img src="{% thumbnail upload.upload.url 200x50 %}" width="{{ upload.width }}" height="{{ upload.height }}" class="{{ options.class }}" class="{{ options.size }}" alt="{% if options.alt %}{{ options.alt }}{% else %}{{ upload.title }}{% endif %}" /> {% endspaceless %} I get the error: Exception Value: Caught an exception while rendering: Source file: '/media/uploads/DSC_0014.jpg' does not exist. I figured the thumbnail needs the absolute path so tried putting that in the template, and that works. i.e this works: {% thumbnail '/Users/me/media/uploads/DSC_0014.jpg' 200x50 %} So basically i need to generate the absolute path to the file give the relative path (to web root). You could do this by passing the MEDIA_ROOT setting to the template, but the reason i want to do a template tag is to programmatically set the image size.

  • Overlaying 2D paths on UIImage without scaling artifacts

    - by tat0
    I need to draw a path along the shape of an image in a way that it is always matching its position on the image independent of the image scale. Think of this like the hybrid view of Google Maps where streets names and roads are superimposed on top of the aerial pictures. Furthermore, this path will be drawn by the user's finger movements and I need to be able to retrieve the path keypoints on the image pixel coordinates. The user zooms-in in order to more precisely set the paths location. I manage to somehow make it work using this approach: -Create a custom UIView called CanvasView that handles touches interaction and delivers scaling, rotation, translation values to either the UIImageView or PathsView (see bellow) depending on a flag: deliverToImageOrPaths. -Create a UIImageView holding the base image. This is set as a children of CanvasView -Create a custom UIView called PathsView that keeps track of the 2D paths geometry and draws itself with a custom drawRect. This is set as children of the UIImageView. So hierarchy: CanvasView - UIImageView -PathsView In this way when deliverToImageOrPaths is YES, finger gestures transforms both the UIImageView and its child PathsView. When deliverToImageOrPaths is NO the gestures affect only the PathsView altering its geometry. So far so good. QUESTION: The problem I have is that when scaling the base UIImageView (via its .transform property) the PathsView is scaled with aliasing artifacts. drawRect is still being called on the PathsView but I guess it's performing the drawing using the original buffer size and then interpolating. How can I solve this issue? Are there better ways to implement these features? PS: I tried changing the PathsView layer class to CATiledLayer with levelsOfDetailBias 4 and levelsOfDetail 4. It solves the aliasing problem to some extent but it's unacceptable slow to render.

  • CAShapeLayer slowing down interface rotation

    - by MrMage
    Hi, I am trying to move some custom drawing code from a view into a CAShapeLayer, which then get added as a sublayer to the original view's CALayer. This also works well, but when rotating the device, the animation starts to stutter, e.g. you just see the frame in the original orientation and then the final orientation, with at most one frame in between - not smooth at all. Slide-in and slide-out animations of the corresponding UIViewController are a bit jerky, too (but not that much). All the CAShapeLayer has in its path is one CGPathAddRect, it is set to be opaque, its opacity is 1.0f and the fillColor is set to opaque blue. When drawing the path directly in the views drawRect method, however, the animation is smooth. So I suppose it has something to do with the CAShapeLayer being animated during the rotation. Could you tell me how to either get rid of those jerkiness or just hide the CAShapeLayer when animating? Getting back to just draw CGPaths directly is not an option to me because I rely on the ability of CAShapeLayer to animate its path (it is not animated in my tries with rotating the view). /update: this also happens when the rotating UIViewControllers view contains a view with a subclass of CAGradientLayer as its layerClass (e.g. a view with a gradient layer as background). Cheers MrMage

  • [Google Maps] Trouble with invalid argument when switching jQueryUI based tabs

    - by Chad
    Here's a page with the issue To reproduce the error, using IE - click the directions tab, then any of the others. What I'm trying to do is this: On page load, do nothing really. However, when the directions tab loads - setup the map. Like so: $('#tabs').bind('tabsshow', function(event, ui) { if (ui.panel.id == "tabs-5") { // get map for directions var dirMap = new GMap2($("div#dirMap").get(0)); dirMap.setCenter(new GLatLng(35.79648921414565,139.40663874149323), 12); dirMap.enableScrollWheelZoom(); dirMap.addControl(new PanoMapTypeControl()); geocoder = new GClientGeocoder(); $("#dirMap").resizable({ stop: function() { dirMap.checkResize(); } }); // clear dirText $("div#dirMapText").html(""); dirMap.clearOverlays(); var polygon = new GPolygon([new GLatLng(35.724496338474104,139.3444061279297),new GLatLng(35.74748750802863,139.3363380432129),new GLatLng(35.75765724051559,139.34303283691406),new GLatLng(35.76545779822543,139.3418312072754),new GLatLng(35.767547103447725,139.3476676940918),new GLatLng(35.75835374997911,139.34955596923828),new GLatLng(35.755149755962755,139.3567657470703),new GLatLng(35.74679090345495,139.35796737670898),new GLatLng(35.74762682821177,139.36294555664062),new GLatLng(35.744422402303826,139.36346054077148),new GLatLng(35.74860206266584,139.36946868896484),new GLatLng(35.735644401200986,139.36843872070312),new GLatLng(35.73843117306677,139.36174392700195),new GLatLng(35.73592308277646,139.3531608581543),new GLatLng(35.72686543236113,139.35298919677734),new GLatLng(35.724496338474104,139.3444061279297)], "#f33f00", 5, 1, "#ff0000", 0.2);dirMap.addOverlay(polygon); // load directions directions = new GDirections(dirMap, $("div#dirMapText").get(0)); directions.load("from: [email protected],139.37083393335342 to: Ruby [email protected],139.40663874149323"); } }); What the heck is causing the error? The IE javascript debugger claims the error lies in main.js, line 139 character 28. (the google maps api file). Which is this line: function zf(a,b){a=a.style;a.width=b.getWidthString();a.height=b.getHeightString()} Any ideas? Thanks in advance!

  • Internet Explorer Warning when embedding Youtube on HTTPS site?

    - by pellepim
    Our application is run over HTTPS which rarely presents any problems for us. When it comes to youtube however, the fact that they do not present any content over SSL connections is giving us some head ache when trying to embed clips. Mostly because of Internet Explorers famous little warning message: "Do you want to view only the webpage content that was delivered securely? This page contains content that will not be delivered using a secure HTTPS ... etc" I've tried to solve this in several ways. The most promising one was to use the ProxyPass functionality in Apache to map to YouTube. Like this: ProxyPass: /youtube/ http://www.youtube.com ProxyPassReverse: /youtube/ http://www.youtube.com This gets rid of the annoying warning. However, the youtube SWF fails to start streaming The SWF i manage to load into the browser simply states : "An error occurred, please try again later". Potential solutions are perhaps: Download youtube FLV:s and serve them out of own domain (gah) Use custom FLV-player and stream only FLV:s from youtube over a https proxy? Update 10 March: I've tried to use Googles Youtube API for ActionScript to load a player. It looked promising at first and I was able to load a player through my https:// proxy. However, the SWF that is loaded contains loads of explicit calls to different non-ssl urls to create authentication links for the FLV-stream and for loading different crossdomain policies. It really seems like we're not supposed to access flv-streams directly. This makes it very hard to bypass the Internet Explorer warning, short of ripping out the FLV:s from youtube and serving them out of your own domain. There are solutions out there for downloading youtubes FLV:s. But that is not compliant with the Youtube terms of use and is really not an option for us.

  • MVC: capture route url's and pass them to javascript function

    - by Tim Geerts
    Short:Is there a way to have a route-definition that will pass the "CONTROLLER/ACTION" string value to a javascript function in stead of actually going straight for the controller action? More:I have a masterpage which contains the navigation of the site. Now, all the pages need this navigation wrapped around it at all times, but because I didn't want the navigation to constantly load with each pagecall, I changed all my pages to partialviews. These partial views are loaded via the JQuery.Load() method whenever a menu item is clicked in the navigation. This all worked very good, up till now because I noticed it's also a requirement of the website to be able to link directly to page X, rather then default.aspx. So, as an example:The main page is my "default.aspx" page, this utilizes my master page with the nagivation around it. And each call to a new page uses a javascript function that loads that particular partial view inside a div that is known in my masterpage. So, the url never changes away from "default.aspx", but my content changes seemlesly. The problem is, those url's also need to be available when typed directly into the address bar. But, they're partial views, so loading them directly from the address bar makes them display without any masterpages around them. Therefore my question if it might be possible to capture the route typed into the address bar and pass that on to my javascript function that will load that route in the content div. (I hope I explained it ok enough, if not, feel free to ask more information)

  • JSON Serialization of a Django inherited model

    - by Simon Morris
    Hello, I have the following Django models class ConfigurationItem(models.Model): path = models.CharField('Path', max_length=1024) name = models.CharField('Name', max_length=1024, blank=True) description = models.CharField('Description', max_length=1024, blank=True) active = models.BooleanField('Active', default=True) is_leaf = models.BooleanField('Is a Leaf item', default=True) class Location(ConfigurationItem): address = models.CharField(max_length=1024, blank=True) phoneNumber = models.CharField(max_length=255, blank=True) url = models.URLField(blank=True) read_acl = models.ManyToManyField(Group, default=None) write_acl = models.ManyToManyField(Group, default=None) alert_group= models.EmailField(blank=True) The full model file is here if it helps. You can see that Company is a child class of ConfigurationItem. I'm trying to use JSON serialization using either the django.core.serializers.serializer or the WadofStuff serializer. Both serializers give me the same problem... >>> from cmdb.models import * >>> from django.core import serializers >>> serializers.serialize('json', [ ConfigurationItem.objects.get(id=7)]) '[{"pk": 7, "model": "cmdb.configurationitem", "fields": {"is_leaf": true, "extension_attribute_10": "", "name": "", "date_modified": "2010-05-19 14:42:53", "extension_attribute_11": false, "extension_attribute_5": "", "extension_attribute_2": "", "extension_attribute_3": "", "extension_attribute_1": "", "extension_attribute_6": "", "extension_attribute_7": "", "extension_attribute_4": "", "date_created": "2010-05-19 14:42:53", "active": true, "path": "/Locations/London", "extension_attribute_8": "", "extension_attribute_9": "", "description": ""}}]' >>> serializers.serialize('json', [ Location.objects.get(id=7)]) '[{"pk": 7, "model": "cmdb.location", "fields": {"write_acl": [], "url": "", "phoneNumber": "", "address": "", "read_acl": [], "alert_group": ""}}]' >>> The problem is that serializing the Company model only gives me the fields directly associated with that model, not the fields from it's parent object. Is there a way of altering this behaviour or should I be looking at building a dictionary of objects and using simplejson to format the output? Thanks in advance ~sm

  • jQuery Address - redirect after form submit

    - by Stian
    Hello all, I use jQuery and AJAX to load content from links and forms into a content div. In addition I use the Address plugin to enable the back button and refresh. On the server side I use Java and Spring MVC. Since I'm using jQuery Address and AJAX the only page that is directly loaded is "index.html". Everything else is loaded into a content div, and what page to load is specified in the hash, ie. "index.html#/users/add.html" will load "users/add.html". Now, "users/add.html" contains a form for creating a new user. When the form is submitted and everything went OK, the controller redirects to "users/index.html". The problem is that jQuery Address doesn't know about the redirect, so the url will remain "index.html#/users/add.html". And this is a problem when you refresh the page and then get sent back to the form, instead of the index page. Is there a way to fix this problem? Thanks, Stian

  • Capturing exit status from STDIN in Perl

    - by zigdon
    I have a perl script that is run with a command like this: /path/to/binary/executable | /path/to/perl/script.pl The script does useful things to the output for the binary file, then exits once STDIN runs out (< returns undef). This is all well and good, except if the binary exits with a non-zero code. From the script's POV, it thinks the script just ended cleanly, and so it cleans up, and exits, with a code of 0. Is there a way for the perl script to see what the exit code was? Ideally, I'd want something like this to work: # close STDIN, and if there was an error, exit with that same error. unless (close STDIN) { print "error closing STDIN: $! ($?)\n"; exit $?; } But unfortunately, this doesn't seem to work: $ (date; sleep 3; date; exit 1) | /path/to/perl/script.pl /tmp/test.out Mon Jun 7 14:43:49 PDT 2010 Mon Jun 7 14:43:52 PDT 2010 $ echo $? 0 Is there a way to have it Do What I Mean?

  • Modify shell script to monitor/ping multiple ip addresses

    - by Alex
    Alright so I need to constantly monitor multiple routers and computers, to make sure they remain online. I have found a great script here that will notify me via growl(so i can get instant notifications on my phone) if a single ip cannot be pinged. I have been attempting to modify the script to ping multiple addresses, with little luck.

  • Problem mapping HttpHandler --> HTTP Error 404 Not Found

    - by JohnIdol
    I am having problems trying to map an HttpHandler in the web.config. This is the relevant config bit: <httpHandlers> <add verb="*" path="*.hndlr" type="MyAssembly.MyHandler, MyAssembly" validate="false" /> </httpHandlers> When I navigate to http://localhost/myApp/whatever.hndlr I am getting a server error 404 (not found). It's the 1st time I am hooking up an HttpHandler so I might be missing something - any help appreciated! UPDATE: I managed to get it working using both answers so far - who's able to exaplin why it works gets the answer marked! This is my config (won't work if Don't have both - I am running IIS7 in classic mode) System.web: <httpHandlers> <add verb="*" path="*MyHandler.hndlr" type="MyAssembly.MyAssemblyHandler, MyAssembly" validate="false"/> </httpHandlers> System.webserver: <handlers> <add name="MyHandler" verb="*" path="*MyHandler.hndlr" type="MyAssembly.MyAssemblyHandler, MyAssembly" validate="false"/> </handlers>

  • WPF Border DesiredHeight

    - by Joseph Sturtevant
    The following Microsoft example code contains the following: <Grid> ... <Border Name="Content" ... > ... </Border> </Grid> <ControlTemplate.Triggers> <Trigger Property="IsExpanded" Value="True"> <Setter TargetName="ContentRow" Property="Height" Value="{Binding ElementName=Content,Path=DesiredHeight}" /> </Trigger> ... </ControlTemplate.Triggers> When run, however, this code generates the following databinding error: System.Windows.Data Error: 39 : BindingExpression path error: 'DesiredHeight' property not found on 'object' ''Border' (Name='Content')'. BindingExpression:Path=DesiredHeight; DataItem='Border' (Name='Content'); target element is 'RowDefinition' (HashCode=2034711); target property is 'Height' (type 'GridLength') Despite this error, the code works correctly. I have looked through the documentation and DesiredHeight does not appear to be a member of Border. Can anyone explain where DesiredHeight is coming from? Also, is there any way to resolve/suppress this error so my program output is clean?

  • Django sphinx works only after app restart.

    - by Lhiash
    Hi, I've set up django-sphinx in my project, which works perfectly only for some time. Later it always returns empty result set. Surprisingly restarting django app fixes it. And search works again but again only for short time (or very limiter number of queries). Heres my sphinx.conf: source src_questions { # data source type = mysql sql_host = xxxxxx sql_user = xxxxxx #replace with your db username sql_pass = xxxxxx #replace with your db password sql_db = xxxxxx #replace with your db name # these two are optional sql_port = xxxxxx #sql_sock = /var/lib/mysql/mysql.sock # pre-query, executed before the main fetch query sql_query_pre = SET NAMES utf8 # main document fetch query sql_query = SELECT q.id AS id, q.title AS title, q.tagnames AS tags, q.html AS text, q.level AS level \ FROM question AS q \ WHERE q.deleted=0 \ # optional - used by command-line search utility to display document information sql_query_info = SELECT title, id, level FROM question WHERE id=$id sql_attr_uint = level } index questions { # which document source to index source = src_questions # this is path and index file name without extension # you may need to change this path or create this folder path = /home/rafal/core_index/index_questions # docinfo (ie. per-document attribute values) storage strategy docinfo = extern # morphology morphology = stem_en # stopwords file #stopwords = /var/data/sphinx/stopwords.txt # minimum word length min_word_len = 3 # uncomment next 2 lines to allow wildcard (*) searches min_infix_len = 1 enable_star = 1 # charset encoding type charset_type = utf-8 } # indexer settings indexer { # memory limit (default is 32M) mem_limit = 64M } # searchd settings searchd { # IP address on which search daemon will bind and accept # optional, default is to listen on all addresses, # ie. address = 0.0.0.0 address = 127.0.0.1 # port on which search daemon will listen port = 3312 # searchd run info is logged here - create or change the folder log = ../log/sphinx.log # all the search queries are logged here query_log = ../log/query.log # client read timeout, seconds read_timeout = 5 # maximum amount of children to fork max_children = 30 # a file which will contain searchd process ID pid_file = searchd.pid # maximum amount of matches this daemon would ever retrieve # from each index and serve to client max_matches = 1000 } and heres my search part from views.py: content = Question.search.query(keywords) if level: content = content.filter(level=level)#level is array of integers There are no errors in any logs, it just isnt returning any results. All help would be most appreciated.

  • How to compile ocaml to native code

    - by Indra Ginanjar
    i'm really interested learning ocaml, it fast (they said it could be compiled to native code) and it's functional. So i tried to code something easy like enabling mysql event scheduler. #load "unix.cma";; #directory "+mysql";; #load "mysql.cma";; let db = Mysql.quick_connect ~user:"username" ~password:"userpassword" ~database:"databasename"();; let sql = Printf.sprintf "SET GLOBAL EVENT_SCHEDULER=1;" in (Mysql.exec db sql);; It work fine on ocaml interpreter, but when i was trying to compile it to native (i'm using ubuntu karmic), neither of these command worked ocamlopt -o mysqleventon mysqleventon.ml unix.cmxa mysql.cmxa ocamlopt -o mysqleventon mysqleventon.ml unix.cma mysql.cma i also tried ocamlc -c mysqleventon.ml unix.cma mysql.cma all of them resulting same message File "mysqleventon.ml", line 1, characters 0-1: Error: Syntax error Then i tried to remove the "# load", so the code goes like this let db = Mysql.quick_connect ~user:"username" ~password:"userpassword" ~database:"databasename"();; let sql = Printf.sprintf "SET GLOBAL EVENT_SCHEDULER=1;" in (Mysql.exec db sql);; The ocamlopt resulting message File "mysqleventon.ml", line 1, characters 9-28: Error: Unbound value Mysql.quick_connect I hope someone could tell me, where did i'm doing wrong.

  • Cocoa App with Python extension which use Scipy -> ImportError: No module named scipy

    - by Snej
    Hi: I have installed Scipy (via macports) for Python on my Mac and it runs fine when running Python scripts. But now I'm using Scipy (via PyObjc) for calculations embedded in a Cocoa App frontend. The following error occurs: ImportError: No module named scipy I am using the "Python.framework" in XCode. Does anybody know why Scipy module is not found? I even added it manually to the module search path via sys.path.append("/opt/local/var/macports/software/py26-scipy/0.7.1_0+gcc43/opt/local/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/scipy/") EDIT: I found the problem myself. The path should be without "/scipy" at the end. But now I got an architecture problem: ImportError: dlopen(/opt/local/var/macports/software/py26-scipy/0.7.1_0+gcc43/opt/local/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/scipy/fftpack/_fftpack.so, 2): no suitable image found. Did find: /opt/local/var/macports/software/py26-scipy/0.7.1_0+gcc43/opt/local/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/scipy/fftpack/_fftpack.so: mach-o, but wrong architecture EDIT 2: I checked the architectures: Yes, sure it is an architecture problem. But when I run: file /opt/local/var/macports/software/py26-scipy/0.7.1_0+gcc43/opt/local/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/scipy/fftpack/_fftpack.so I get a result Mach-O 64-bit bundle x86_64. And the Mac OS 10.6 PYTHON is: Mach-O universal binary with 3 architectures /usr/bin/python (for architecture x86_64): Mach-O 64-bit executable x86_64 /usr/bin/python (for architecture i386): Mach-O executable i386 /usr/bin/python (for architecture ppc7400): Mach-O executable ppc I build the XCode project as x86_64.

  • What Scheme Does Ghuloum Use?

    - by Don Wakefield
    I'm trying to work my way through Compilers: Backend to Frontend (and Back to Front Again) by Abdulaziz Ghuloum. It seems abbreviated from what one would expect in a full course/seminar, so I'm trying to fill in the pieces myself. For instance, I have tried to use his testing framework in the R5RS flavor of DrScheme, but it doesn't seem to like the macro stuff: src/ghuloum/tests/tests-driver.scm:6:4: read: illegal use of open square bracket I've read his intro paper on the course, An Incremental Approach to Compiler Construction, which gives a great overview of the techniques used, and mentions a couple of Schemes with features one might want to implement for 'extra credit', but he doesn't mention the Scheme he uses in the course. Update I'm still digging into the original question (investigating options such as Petit Scheme suggested by Eli below), but found an interesting link relating to Gholoum's work, so I am including it here. [Ikarus Scheme](http://en.wikipedia.org/wiki/Ikarus_(Scheme_implementation)) is the actual implementation of Ghuloum's ideas, and appears to have been part of his Ph.D. work. It's supposed to be one of the first implementations of R6RS. I'm trying to install Ikarus now, but the configure script doesn't want to recognize my system's install of libgmp.so, so my problems are still unresolved. Example The following example seems to work in PLT 2.4.2 running in DrEd using the Pretty Big (require lang/plt-pretty-big) (load "/Users/donaldwakefield/ghuloum/tests/tests-driver.scm") (load "/Users/donaldwakefield/ghuloum/tests/tests-1.1-req.scm") (define (emit-program x) (unless (integer? x) (error "---")) (emit " .text") (emit " .globl scheme_entry") (emit " .type scheme_entry, @function") (emit "scheme_entry:") (emit " movl $~s, %eax" x) (emit " ret") ) Attempting to replace the require directive with #lang scheme results in the error message foo.scm:7:3: expand: unbound identifier in module in: emit which appears to be due to a failure to load tests-driver.scm. Attempting to use #lang r6rs disables the REPL, which I'd really like to use, so I'm going to try to continue with Pretty Big. My thanks to Eli Barzilay for his patient help.
