Dash surrounding text

- by Brandon Hansen

Given the above dynamically generated text (meaning that I can't just use an image), I am trying to recreate the design using just html and css selectors. I would like to just use a single h4 with the containing text, but am open to other solutions. I would prefer to not use absolute positioning, but again, if that is the only way, then so be it. I have tried surrounding with span tags, but those are inline elements that don't have an inherent width. The h4 will be nested within a div, though not always of the same class or id. Any ideas or resources to get me started?

Why are these divs repelling each other?

- by Terminal Frost

<html> <div style="width:200px;"> <div style="background:red;height:5px"></div> <div style="background:yellow"> Magnets? </div> <div style="background:green;height:5px"></div> </div> </html> Rendering with "Magnets?" wrapped in h3 tags How come the divs cease to be contiguous if "Magnets?" is wrapped in a paragraph or heading tag?

Is there a shorthand version of HTML available?

- by monguin

I remember reading an article about a shorthand version, or extension, of HTML a few months ago. Its purpose was to make HTML code significantly more concise, by removing end tags, and it may have allowed loops of some sort as well. I want to use it now, but I can't seem to remember what it was called. Searching online, I found HAML, but HAML syntax doesn't look like the example that I remember from the article. The syntax from the article made use of right angle brackets, which were a sort of replacement for indentation. Can anyone identify this language?

exec() function doesn't rule svn checkout

- by bahamut100

Hi, I'm writing some functions in php using exec() to interrogate a svn. The commands exec("svn list ".$myurl) works. Now, I try to get a path on a svn repository with the checkout command. When I put the command "svn checkout http://core.wordress.org/tags/2.9.2/ last-version" directly in the console, it works. But when I do this from a php script using exec(), like this : exec("svn checkout ".$myurl, $dir) it doesn't work. Have you an idea ??

Extract anything that looks like links from large amount of data in python

- by Riz

Hi, I have around 5 GB of html data which I want to process to find links to a set of websites and perform some additional filtering. Right now I use simple regexp for each site and iterate over them, searching for matches. In my case links can be outside of "a" tags and be not well formed in many ways(like "\n" in the middle of link) so I try to grab as much "links" as I can and check them later in other scripts(so no BeatifulSoup\lxml\etc). The problem is that my script is pretty slow, so I am thinking about any ways to speed it up. I am writing a set of test to check different approaches, but hope to get some advices :) Right now I am thinking about getting all links without filtering first(maybe using C module or standalone app, which doesn't use regexp but simple search to get start and end of every link) and then using regexp to match ones I need.

Drupal rendering incomplete views

- by Paul

I got tapped to do some quick maintenance on a recently migrated Drupal site. I'm pretty new to Drupal, so hopefully the problem is something that more experienced guys will figure out quick. Behavior is as follows. The public content works fine as far as I can tell. When I go to login, the login form renders correctly, but when I post the form w/ my credentials, I get back a blank page (not a 404; looks like a 200 to the /user URL, but all the gets rendered is empty Head and body tags). If i refresh the page, I get the content of my profile view, but none of the site chrome or CSS. Note that this is not an issue on the site it was migrated from, so it seems like something wasn't copied over correctly. The site's not public, so I can't provide a URL, sorry!

FACEBOOK LINTER ERROR: value for property 'og:image:url' could not be parsed as type 'url'

- by Martin Devarda

I've read all threads in stack overflow about this issue, but my problem persists. THE PROBLEM IS ON THIS PAGE: http://www.organirama.it/minisite-demo/001.html THE PAGE CONTAINS THIS TAGS <meta property="og:title" content="A wonderful page" /> <meta property="og:type" content="video.movie" /> <meta property="og:url" content="http://www.organirama.com/minisite-demo/001.html" /> <meta property="og:image" content="http:/www.organirama.com/minisite-demo/photos-small/001.png" /> <meta property="og:site_name" content="Organirama"/> <meta property="fb:admins" content="1468447924"/> LINTER ERROR Object at URL 'http://www.organirama.com/minisite-demo/001.html' of type 'video.movie' is invalid because the given value 'http:/www.organirama.com/minisite-demo/photos-small/001.png' for property 'og:image:url' could not be parsed as type 'url'. WHAT I DISCOVERED The problem seems somehow related to the domain. Infact, if I make og:image point to another image on another domain, everything works.

Writing custom Django form fields and widgets

- by hekevintran

Django has very good documentation that describes how to write custom database fields and custom template tags and filters. I cannot find the document that describes how to write custom form fields and widgets. Does this document exist? The way I've been able to write custom form fields and widgets is by reading the Django source code and imitating what I see there. I know that there are still things about implementing fields and widgets that I do not completely understand because I have not read any high level document that describes their interfaces.

Hi, I wrote a little search script for a client, it works and words get highlited, BUT...

How could I prevent this? Edit: So this is what I need: A regex replace function that replaces all matched search strings EXCEPT the ones that are located inside a href attribute Greets, nick

How to extract img src, title and alt from html using php?

- by Sam

I would like to create a page where all images which reside on my website are listed with title and alternative representation. I already wrote me a little program to find and load all html files, but now I am stuck at how to extract src, title and alt from the html < img src="/image/fluffybunny.jpg" title="Harvey the bunny" alt="a cute little fluffy bunny"/ I guess this should be done with some regex, but since the order of the tags may vary, and I need all of them, I don't really know how to parse this in an elegant way (I could do it the hard char by char way, but thats painful).

Using indentation to make CSS more readable? (making parents and children more identifiable in CSS)

- by janoChen

I've been always guiding myself with the following CSS structure: #nav { } #nav li { } #nac li a { } This structure tells me clearly who is the parent and the child. But in a recent article (I think it was CSS Trick) someone said that CSS is read from right to left. So the more tags I had the slower it will be (and sometimes I think its unnecessary to write every single tag involve in the selector). So it may be something like this: #nav { } #special-link { } where #special-link is #nav's child. I know this is not a big problem in a simple stylesheet but in a big one I always would get confused about who is who's parent and child. Another solution would be: #nav { } #special-link { } Indentation How do you solve with this CSS dilemma?

Need a push in the write direction, to write my first functional test in Rails?

- by Jason

Hi, I've read quiet a bit of documentation over the last few days about testing in Rails, I'm sitting down to write my first real test and not 100% sure how to tie what I have learned together to achieve the following functional test (testing a controller) I need to send a GET request to a URL and pass 3 parameters (simple web-service), if the functionality works the keyword "true" is simply returned, otherwise the keyword "false" is returned - its in only value returned & not contained in any , or other tags. The test should assert that if "true" is returned the test is successful. This is probably very simple so apologies for such a non-challenging question. If anyone could point me in the write direction on how I can get started, particularly how I can test the response, I'd be very grateful! Thanks!

Prevent ASP.NET from encoding strings on output

- by Darkwater23

How can I stop ASP.Net from encoding anchor tags in List Items when the page renders? I have a collection of objects. Each object has a link property. I did a foreach and tried to output the links in a BulletedList, but ASP encoded all the links. Any idea? Thanks! Here's the offending snippet of code. When the user picks a specialty, I use the SelectedIndexChange event to clear and add links to the BulletedList: if (SpecialtyList.SelectedIndex > 0) { PhysicianLinks.Items.Clear(); foreach (Physician doc in docs) { if (doc.Specialties.Contains(SpecialtyList.SelectedValue)) { PhysicianLinks.Items.Add(new ListItem("<a href=\"" + doc.Link + "\">" + doc.FullName + "</a>")); } } }

How does one validate html that's generated from JS running in the browser?

- by Henry Rose

The page in question has very skeletal html sent over the wire to facilitate the building of a complicated UI in javascript. I'm now encountering a strange browser compatibility issue that feels very much like I've got a markup problem somewhere on the page. I've validated the page as it comes across the wire using the W3C tool and ensured there are no issues in that html. I've also tried validating the output of running on the browser console: document.getElementsByTagName('html')[0].outerHTML I find that the output of the above introduces lots of new issues, such as removing the trailing '/' in self closing tags. This added noise is distracting, but it also makes me uneasy about validating this method. How do you validate markup that's rendered client side?

Using Nokogiri to scrape groupon deal

I'm following the Nokogiri railscast to write a scraper for Groupon.

Checking if a boolean column is true in MySQL/Rails

- by Pygmalion

Rails and MySQL: I have a table with several boolean columns representing tags. I want to find all the rows for which a specific one of these columns is 'true' (or I guess in the case of MySQL, '1'). I have the following code in my view. @tag = params[:tag] @supplies = Supply.find(:all, :conditions=>["? IS NOT NULL and ? !=''", @tag, @tag], :order=>'name') The @tag is being passed in from the url. Why is it then that I am instead getting all of my @supplies (i.e. every row) rather than just those that are true for the column for @tag. Thanks!

Image display permissions in PHP/Apache

- by Randy

I have a PHP site with a login system, and am trying to make a feature where only specific usernames can view particular images. I think what I'm trying to do is more involved than merely changing the .htaccess file, because a) this won't help discern between users that are/aren't allowed to view the image, and b) if someone enters the exact URL of the image ("directory/images/photos/230ru0q0238rn230nd_asdi0nqn8.jpg") they can still view the image (since it's a physical file in the directory, and not text in a DB, etc.). Again, restricting via .htaccess would restrict the directory as a whole, or all files in it, so I can't figure out how it would work. Ideally, all images would be blocked by trying to access them directly through their direct URL, and the image would only appear between <img> tags if the user's session/username is valid, else they get an error message. I've heard the term ACL but I'm not sure this is related to what I'm trying to do.

How to pass object in :with field for a link_to_remote call

- by mathee

I have an object elem that I'd like to pass to the remove_tag_from_cart method. Here is my attempt: -elem = @tags[1] #{elem.name}#{link_to_remote image_tag('x.png'), :url => {:controller => 'questions', :action => 'remove_tag_from_cart'}, :with => {:tag_to_remove => :elem}} The :with clause isn't working correctly. The image does not even show up. If I take out the :with clause, then the link properly shows up and calls the method correctly, but I need the elem object in order to remove it from the cart. Suggestions?

Check if XML node is empty

- by Vinit

I have a simple XML structure like <main> <node1></node1> </main> and this can have any number of sub-nodes or values like: <main> <node1><p>texttext text</p> more text <br/></node1> </main> I want to check if the node is empty or not: I'm doing something like: <xsl:if test="string-length(main/node1//text())>0"> But it does not work as if there are multiple tags, then string-length function will break coz of multiple arguments. Any help to solve this issue is really appreciated.

Prototyping Qt/C++ in Python

- by tstenner

I want to write a C++ application with Qt, but build a prototype first using Python and then gradually replace the Python code with C++. Is this the right approach, and what tools (bindings, binding generators, IDE) should I use? Ideally, everything should be available in the Ubuntu repositories so I wouldn't have to worry about incompatible or old versions and have everything set up with a simple aptitude install. Is there any comprehensive documentation about this process or do I have to learn every single component, and if yes, which ones? Right now I have multiple choices to make: Qt Creator, because of the nice auto completion and Qt integration. Eclipse, as it offers support for both C++ and Python. Eric (haven't used it yet) Vim PySide as it's working with CMake and Boost.Python, so theoretically it will make replacing python code easier. PyQt as it's more widely used (more support) and is available as a Debian package. Edit: As I will have to deploy the program to various computers, the C++-solution would require 1-5 files (the program and some library files if I'm linking it statically), using Python I'd have to build PyQt/PySide/SIP/whatever on every platform and explain how to install Python and everything else.

Drupal, Lightbox: cannot edit the content inside

- by Patrick

hi, I'm using Drupal and Lightbox module to display the content of articles in this website: donatellabernardi.ch/drupal if you click on an article the lightbox is displayed. However I have 2 problems with it: 1) I cannot use the libraries such as the tooltip library qTip from it. (If you move the mouse over the balls, you'll see the tooltips) 2) I cannot invert the title with the balls (tags), because it seems that the template of the node in the lightbox is not controlled by my theme. I tried also to change the node template (in the drupal root folder), swapping title and meta data but it didn't work. thanks
