  • Working with Lightweight User Interface Toolkit (LWUIT) 1.4

    - by janice.heiss(at)oracle.com
    Vikram Goyal's informative and practical article, "Working with Lightweight User Interface Toolkit (LWUIT) 1.4," shows developers how to best take advantage of LWUIT 1.4. LWUIT is a user interface library designed to bring uniformity and cross mobile interface functionality to applications developed using Java Platform, Micro Edition (Java ME). Version 1.4 offers support for XHTML, multi-line text fields, and customization to the virtual keyboard.Goyal notes in the article that, "Perhaps the most important feature of this release is the ability for LWUIT to support XHTML. Specifically, it now supports XHTML MP (Mobile Platform) 1.0, a version of XHTML designed for mobile phones. To be even more specific, it now supports CSS styling for the HTMLComponent within the LWUIT library through Wireless Application Protocol CSS (WCSS)." Read the entire article here.

  • How do I best remove the unicode characters that XHTML regards as non-valid using php?

    - by Andrew Stacey
    I run a forum designed to support an international mathematics group. I've recently switched it to unicode for better support of international characters. In debugging this conversion, I've discovered that not all unicode characters are considered as valid XHTML (the relevant website appears to be http://www.w3.org/TR/unicode-xml/). One of the steps that the forum software goes through before presenting the posts to the browser is an XHTML validation/sanitisation step. It seems a reasonable idea that at that stage it should remove any unicode characters that XHTML doesn't like. So my question is: Is there a standard (or best) way of doing this in PHP? (The forum is written in PHP, by the way.) I guess that the failsafe would be a simple str_replace (if that's also the best, do I need to do anything extra to make sure it works properly with unicode?) but that would involve me having to go through the XHTML DTD (or the above-referenced W3 page) carefully to figure out what characters to list in the search part of str_replace, so if this is the best way, has someone already done that so that I can steal, err, copy, it? (Incidentally, the character that caused the problem was U+000C, the 'formfeed', which (according to the W3 page) is valid HTML but invalid XHTML!)

  • Should programming languages be strict or loose?

    - by Ralph
    In Python and JavaScript, semi-colons are optional. In PHP, quotes around array-keys are optional ($_GET[key] vs $_GET['key']), although if you omit them it will first look for a constant by that name. It also allows 2 different styles for blocks (colon, or brace delimited). I'm creating a programming language now, and I'm trying to decide how strict I should make it. There are a lot of cases where extra characters aren't really necessary and can be unambiguously interpreted due to priorities, but I'm wondering if I should still enforce them or not to encourage good programming habits. What do you think?

  • I want to turn VB.Net Option Strict On

    - by asjohnson
    I recently found out about strong typing in VB.Net (naturally it was on here, thanks!) and am deciding I should take another step toward being a better programmer. I went from vba macros - VB.Net, because I needed a program that I could automate and I never read anything about strong typing, so I kind of fell into the VB.Net default trap. Now I am looking to turn it on and sort out this whole type thing. I was hoping someone could direct me towards some resources to make this transistion as painless as possible. I have read around some and ctype seems to come up a lot, but past that I am at a bit of a loss. What are the benefits of switching? Is there more to it than just using ctype to cast things? I feel like there is a good article that I have failed to come across and any direction would be great. Would a good approach to be to rewrite a program that is written with option strict off and note differences?

  • Strict Pomodoro and other time management Chrome extensions

    - by kerry
    I have recently begun using the Pomodoro Technique to increase my productivity. However, I still find myself getting sucked in to the vortex of useless information that is the internet. With that in mind I began searching for a useful chrome extension to replace the Android Pomodoro app I have been using to manage my ‘doros. I even considered writing it myself. Luckily, I stumbled on one that had a similar featureset to what I was looking for. Strict Pomodoro is an excellent Chrome extension for practicing Pomodoro. Though lacking a few key features, such as the ability to set the duration of your pomodoros and breaks, it still has a key feature that helps me stay on task. It blocks time sucking websites. You can set filter lists and it will keep you from accessing them during a Pomodoro. Effectively reminding you to stay on task. Also, the author readily admits that it was quickly put together and new features may be added down the road. For now, it is still an excellent option. For those of you who do not practice Pomodoro but are trying to stay on task. The StayFocusd extension will effectively manage the amount of time you spend on useless (non-productive) sites. It also has a rich feature set that may be better for your work habits. OK, breaks over. Time to get back to work. 25 minutes at a time.

  • Why does my simple strict XHTML file give errors when I include jquery?

    I'm trying to make a simple strict HTML file that includes jquery: <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en"> <head> <title>Test File</title> <link href="http://ajax.googleapis.com/ajax/libs/jqueryui/1.8/themes/base/jquery-ui.css" rel="stylesheet" type="text/css"/> <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4/jquery.min.js"></script> <script src="http://ajax.googleapis.com/ajax/libs/jqueryui/1.8/jquery-ui.min.js"></script> </head> <body> </body> </html> But Firefox displays the following errors in the error console when I try to load it: Error: d.style is undefined Source File: http://ajax.googleapis.com/ajax/libs/jquery/1.4/jquery.min.js Line: 33 Error: jQuery is not defined Source File: http://ajax.googleapis.com/ajax/libs/jqueryui/1.8/jquery-ui.min.js Line: 19 Help!

  • Django Template For Loop Removing <img> Self-Closing

    - by Zack
    Django's for loop seems to be removing all of my <img> tag's self-closing...ness (/>). In the Template, I have this code: {% for item in item_list %} <li> <a class="left" href="{{ item.url }}">{{ item.name }}</a> <a class="right" href="{{ item.url }}"> <img src="{{ item.icon.url }}" alt="{{ item.name }} Logo." /> </a> </li> {% endfor %} It outputs this: <li> <a class="left" href="/some-url/">This is an item</a> <a class="right" href="/some-url/"> <img src="/media/img/some-item.jpg" alt="This is an item Logo."> </a> </li> As you can see, the <img> tag is no longer closed, and thus the page doesn't validate. This isn't a huge issue since it'll still render properly in all browsers, but I'd like to know how to solve it. I've tried wrapping the whole for loop in {% autoescape off %}...{% endautoescape %} but that didn't change anything. All other self-closed <img> tags in the document outside the for loop still properly close.

  • Replace a word in an XML file through StreamReader in XNA?

    - by kcoppock
    Okay, so this is sort of a hack...but it may have to be. I'm writing an app in XNA, which from my research into this problem apparently doesn't support XML version 1.1. I'm reading in the contents of an ePub document, and one of the newer books contains its content directory as a version 1.1 XML document. This causes my program to crash. However, the structure is the same as the rest, the only thing that should be keeping it from working is the hard-coded "1.0" in the XmlDocument class. Is it possible that I could read in the file from the stream, see if it contains: <?xml version="1.1" encoding="UTF-8" standalone="no"?> and simply replace it with "1.0"? Then I could pull it in as an XmlDocument. I'm not doing any writing to the file, or any complex structural reading, just looking for a few specific nodes, and pulling in the values, so I don't know what the ramifications of this would be.

  • How can I embed a XML document inside a XHTML document?

    - by Oriol
    For example, how can I embed <?xml version="1.0" encoding="utf-8"?> <root> <node><![CDATA[Text]]></node> </root> in my XHTML? I know I can put it in a CDATA section... <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="content-type" content="text/html; charset=UTF-8" /> <title>My title</title> </head> <body> <p>I am a XHTML paragraph!</p> <div> <![CDATA[ <?xml version="1.0" encoding="utf-8"?> <root> <node>Text</node> </root> ]]> </div> </body> </html> ... but then I have to remove XML file's CDATA sections and the XML is parsed as text instead of XML. Then, I get this... ... but I want something like this:

  • Why Prefer Tableless XHTML Or HTML?

  • Strict pointer aliasing: any solution for a specific problem?

    - by doublep
    I have a problem caused by breaking strict pointer aliasing rule. I have a type T that comes from a template and some integral type Int of the same size (as with sizeof). My code essentially does the following: T x = some_other_t; if (*reinterpret_cast <Int*> (&x) == 0) ... Because T is some arbitary (other than the size restriction) type that could have a constructor, I cannot make a union of T and Int. (This is allowed only in C++0x only and isn't even supported by GCC yet). Is there any way I could rewrite the above pseudocode to preserve functionality and avoid breaking strict aliasing rule? Note that this is a template, I cannot control T or value of some_other_t; the assignment and subsequent comparison do happen inside the templated code. (For the record, the above code started breaking on GCC 4.5 if T contains any bit fields.)

  • Serve up syntactic XHTML5 using the text/html MIME type?

    - by cboettig
    I have a site currently written with HTML5 tags. I'd like to be able to parse the site as XML, with support for namespaces, etc, to facilitate programmatic extraction of data. Currently I have <!DOCTYPE html> and <meta charset="utf-8"> Which I gather is equivalent in HTML5 to explicitly setting the content-types as <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> for my current setup. In order to serve XML it sounds like the right thing to do is <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> Should I also change my Content-Type to <meta http-equiv="content-type" content="application/xhtml+xml; charset=iso-8859-1" /> Or is that not necessary? What is the advantage of having content-type be "application/xhtml+xml"? What is the disadvantage? (Sounds like it may break internet explorer rendering of the site? but maybe that information is out of date now?) Many thanks!

  • Is strict mode more performant?

    - by sje397
    Does executing javascript within a browser in 'strict mode' make it more performant, in general? Do any of the major browsers do additional optimisation or use any other techniques that will improve performance in strict mode? Edit: Since none of the major engines actually implement strict mode, I'll rephrase slightly: Is strict mode intended, amongst its other goals, to allow browsers to introduce additional optimisations or other performance enhancements?

  • Why does Perl's strict not let me pass a parameter hash?

    - by Thariama
    I hava a perl subroutine where i would like to pass parameters as a hash (the aim is to include a css depending on the parameter 'iconsize'). I am using the call: get_function_bar_begin('iconsize' => '32'); for the subroutine get_function_bar_begin: use strict; ... sub get_function_bar_begin { my $self = shift; my %template_params = %{ shift || {} }; return $self->render_template('global/bars /tmpl_incl_function_bar_begin.html',%template_params); } Why does this yield the error message: Error executing run mode 'start': undef error - Can't use string ("iconsize") as a HASH ref while "strict refs" in use at CheckBar.pm at line 334 Am i doing something wrong here? Is there an other way to submit my data ('iconsize') as a hash? (i am still new to Perl) EDIT: Solution which worked for me. I didn't change the call, but my function: sub get_function_bar_begin { my $self = shift; my $paramref = shift; my %params = (ref($paramref) eq 'HASH') ? %$paramref : (); my $iconsize = $params{'iconsize'} || ''; return $self->render_template('global/bars/tmpl_incl_function_bar_begin.html', { 'iconsize' => $iconsize, } ); }

  • How do you embed XHTML into APT file when using Maven to generate a site?

    - by Clinton
    I am using maven to generate a website for a Java project, which uses APT "Almost Plain Text" as a wiki like markup. Maven takes this and turns it into XHTML. I already have a custom template/skin that I am using for the site, but the index page will have a couple of extra custom design elements that are beyond the capabilities of APT. So how can you add xhtml to the apt file so that it gets correctly embedded in the final output? Thanks.

  • Notepad++ incorrect syntax highlithing?

    - by user360919
    So I want to build a XHTML 1.0 Strict based website. Using Notepad++ for syntax highlighting came as an idea to me. But when I tried to put the XML declaration (as stated in the spec, proper XHTML pages should use a XML declaration and be served as application/xhtml+xml) I can't get the entire document highlighted propperly. Here is the code I used for a basic page: <?xml version="1.0" encoding="UTF-8" standalone="no" ?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en-us" lang="en-us"> <head> <meta http-equiv="Content-Type" content="application/xhtml+xml; charset=UTF-8" /> <title>Page</title> <script type="application/javascript"> alert("A perfectly valid xHTML page..."); </script> <style type="text/css"> #test { text-align: center; } </style> </head> <body> <h1 id="test">TEST</h1> </body> </html> Paste this in Notepad++ and you'll see that it won't highlight the code between <script type="application/javascript"> and </script> (it renders its background white) if language is set to XML. If I set the language to HTML, then the script gets correctly highlighted but the XML declaration is not. What to do? How to make a hybrid language - combination of XML and HTML?

  • Is there a Java API for creating a XHTML document?

    - by Bedwyr Humphreys
    I want to provide a simple XHTML representation of each of the resources in a REST web service. At the moment i'm using a StringBuilder to generate these which is both tedious and error prone. I don't see these changing after I publish the service but the process of coding each is a bit painful. Is there a XHTML document writer api? Should I just use an XML writer? Which one? Should I just roll my own basic HTML document class - doctype is the same each time, i just need to set the title, metatags and body content, most of which (but not all content) is already in HTML for the GETs. Or should I just use StringBuilder and stop whining? ;) Thanks.
