Man so much has changed since I learned DirectX 7.
Everywhere I look (except Wikipedia), it says I have to render from DWrite to D2D or GDI before I can do anything.
Is that Wikipedia article wrong? Can I not render to Direct3D?
I'd like to avoid having to render to D2D, since apparently, to get D2D to write to D3D, you have to open up a D3D10.1 device as well.
Does it really take all this just to render text in D3D11?
Unfortunately, Microsoft decided to remove native text support from their DirectX API. Now you can either use DirectWrite, and then as you said render to GDI or D2D, which is somewhat clunky, or alternatively, make your own font-handling class, and use that (which is what I've chosen to done for my project).
There is a good tutorial on how to produce a custom Font-handling class, here: http://www.rastertek.com/dx11tut12.html
Obviously, you should write your own, but it provides a good starting point, and allows you to see all the necessary proceedures (something you will probably want to add will be support for multiple fonts, for which I recommend creating a Font class, which your Font-Handler stores with an associative string in a std::map< char*, Font* >).
Hope this helps! :)

Is there any standard (possibly created after-the-fact) that governs <!DOCTYPE NETSCAPE-Bookmark-file-1> files? If you export bookmarks from either Chrome or Firefox (tried on Windows 10) you get this kind of file, which seems to be HTML of sorts.
I've tried searching the web but found only pragmatic results like parsers in specific programming stacks, or tips and tricks on importing and exporting it.
Is there any standard, RFC, format description, or reference parser, or something similar?
Not even valid HTML it is, neither technically, nor semantically. And it seems that modern browsers interpret the factual standard loosely when writing such files, but luckily also when importing.
The best available format description (probably reverse engineered, yes) seems to be this one:

And it's by Microsoft of all things...
I am trying to create a markdown editor for fun and because I was interested in learning TextKit. I am working on iOS devices only, so I only have UIKit framework at my disposal, also I watched this WWDC18 video which explains some best practices to adopt with TextKit. At first I was really interested in knowing how to get the same result that the video shows at 22:13.
The code shown by the dev in the video makes use of AppKit and it wraps code in that rectangle by replacing the code section with a NSMutableParagraphStyle and by providing a custom NSTextBlock to the latter. As you can guess, I can't subclass NSTextBlock in UIKit and therefore I can't replicate the example shown.
I have something a little bit harder to ask though, what I really wanted to replicate is the GitHub application code block style, this is the final result that I would like to replicate:
As you can see it should have a rounded rectangle with a custom background color and also it needs to be scrollable in order to make code expand as much as it needs (I am not interested in syntax highlighting).
How can I achieve something like this if NSTextBlock is not available in UIKit?
For the moment all I have done is override NSTextStorage to set the correct font to the code section with custom NSAttributedString.
I have investigated in the app and noticed that it is managed by Ryan Nystrom which is the creator of GitHawk prior to moving to GitHub. The GitHawk markdown reader is very similar to the one that you find in the GitHub application and the funny thing is that GitHawk is open source so I took a look at that code and tried to understand how that could be replicated.
Turns out that GitHawk heavily uses IGListKit framework and parses markdown in ListDiffable elements, specifically the code blocks ListDiffables are given to a ListSectionController that created an horizontal UIScrollView to display code.
I gave up trying to understand more on this because GitHawk code is really really entangled and it is really hard, near impossible, to extract the specific functionality.
Just like TImageList contains a collection of images, is there a similar component for generic files?
I know I can embed files as resources, but I'd like the convenience of storing different groups of files in different "TFileList" components, and to be able to retrieve files by name or by their position in the list.
Extra points if such a component allowed some sort of design time preview of the file content (just like TImageList lets you see what each image looks like, at design time).
(I come from Delphi where I wrote my own component to do the above, but before I rewrite and port the property editor and all that to Lazarus, maybe there is already something that is tried and tested...)
Thanks!
You can use pre-defined lazarus TFPGList to specialize list of the type, that you want, for example - UTF8String
But, there's no T<>List as a component, only as object.
So, yes, this feature will be useful and i can implement, if have time,
also, there's a very limited RTTI, which has been updated only a few months ago, so you can access Methods and Properties now, so FP is more systemized, than delphi pascal, but also not so enterprise-developed, which limits it to implementations for common opensource and shareware project problems.
Nevertheless, it is more stable and supported, even my friends can contribute.
I'm relatively new to Expression Engine, and as I'm learning it I am seeing some stuff missing that WordPress has had for a while. A big one for me is shortcodes, since I will use these to allow CMS users to place more complex content in place with their other content.
I'm not seeing any real equivalent to this in EE, apart from a forthcoming plugin that's in private beta.
As an initial test I'm attempting to fake shortcodes by using delimited strings (e.g. #foo#) in the content field, then using a regex to pull those out and pass them to a function that can retrieve the content out of EE's database.
This brings me to a second question, which is that in looking at EE's API docs, there doesn't appear to be a simple means of retrieving the channel entries programmatically (thinking of something akin to WP's built-in get_posts function).
So my questions are:
a) Can this be done?
b) If so, is my method of approaching it reasonable? Or is there something stupidly obvious I'm missing in my approach?
To reiterate, my main objective here is to have some means of allowing people managing content to drop a code in place in their content that will be replaced with channel content.
Thanks for any advice or help you can give me.
Here's a simple example of the functionality you're looking for.
1) Start by installing Low Replace.
2) Create two Global Variables called gv_hello and gv_goodbye with the values "Hello" and "Goodbye" respectively.
3) Put this text into the body of an entry:
[say_hello]
Nice to see you.
[say_goodbye]
4) Put this into your template, wrapping the Low Replace tag around your body field.
{exp:low_replace
find="[say_hello]|[say_goodbye]"
replace="{gv_hello}|{gv_goodbye}"
multiple="yes"
}
{body}
{/exp:low_replace}
5) It should output this into your browser:
Hello
Nice to see you.
Goodbye
Obviously, this is a really simple example. You can put full blown HTML into your global variable. For example, we've used that to render a complex, interactive graphic that isn't editable but can be easily dropped into a page by any editor.
Unfortunately, due to parse order issues, EE tags won't work inside Global Variables. If you need EE tags in your short code output, you'll need to use Low Variables addon instead of Global Variables.
Continued from the comment:
Do you have examples of the kind of shortcodes you want to support/include? Because i have doubts if controlling the page-layout from a text-field or wysiwyg-field is the way to go.
If you want editors to be able to adjust layout or show/hide extra parts on the page, giving them access to some extra fields in the channel, is (imo) much more manageable and future-proof. For instance some selectfields, a relationship (or playa) field, or a matrix, to let them choose which parts to include/exclude on a page, or which entry from another channel to pull content from.
As said in the comment: i totally understand if you want to replace some #foo# tags with images or data from another field (see other answers: nsm-transplant, low_replace). But, giving an editor access to shortcodes and picking them out, is like writing a template-engine to generate ee-template code for the ee-template-engine.
Using some custom fields to let editors pick and choose parts to embed is, i think, much more manageable.
That being said, you could make a plugin to parse the shortcodes from a textareas content, and then program a lot, to fetch data from other modules you want to support. For channel entries you could build out of the channel data library by objectiveHTML. https://github.com/objectivehtml/Channel-Data
I hear you, I too miss shortcodes from WP -- though the reason they work so easily there is the ubiquity of the_content(). With the great flexibility of EE comes fewer blanket solutions.
I'd suggest looking at NSM Transplant. It should fit the bill for you.
There is also a plugin called Shortcode, which you can find here at
Devot-ee
A quote from the page:
Shortcode aims to allow for more dynamic use of content by authors and
editors, allowing for injection of reusable bits of content or even
whole pieces of functionality into any field in EE
I want to add a calendar control to a page that already includes Prototype and Scriptaculous. Not happy with any of the Prototype ones I could find, I'm considring using the YUI Calendar widget.
I this likely to cause any problems?
We have worked hard to make sure that YUI is safe to use with any other library. We namespace everything, as HermanD says, under only one required global (YAHOO) and one optional one (YAHOO_config). We don't modify native objects. And even though Protoype does modify native prototypes, we code defensively so that this doesn't break YUI functionality.
If you find any bugs in using the two together, please let us know.
Regards,
Eric
YUI Team
By default everything in YUI is within the YAHOO namespace, so as long as you sensibly apply namespaces to anything you use from YUI, I would have thought you should be ok.
See: http://developer.yahoo.com/yui/yahoo/
I successfully used the YUI tab control in an app I was already using Prototype and Scriptaculous in and had no problem. The weight of all that is a bit much though if you're looking at a publicly available app. I wouldn't care so much about an internal app, say for a company, but you might want to think about how much JavaScript you're making end users download and the number of separate files they're having to download for the page.
