Inserting a news-feed widget to a page - haskell

I have a page I'd like to embed a news-feed widget into (so that the feed from some remote site will be displayed in my site).
While there are quite a few free news-feed widgets available out there (a partial list is here: http://allwebco-templates.com/support/S_script_newsfeed.htm), They all require insertion of complex code into the html page, while all the parameters are hard-coded into the generated code, which looks something like this:
insertedWidgetText = "<script id=\"scrnewsblock10795953\" type=\"text/javascript\">...script specific parameters go here...</script>"
let feedWidget = toWidgetBody [hamlet|#{preEscapedText insertedWidgetText}|]
This doesn't integrate well with Yesod's approach as it requires specifying to Hamlet that the content is preEscapedText, which in turn disables the ability to use Hamlet's processing to alter parameters of the widget dynamically (So in case I want the widget to use a different source, for example, I need to statically change the quoted text and cannot use Hamlet's variable substitution).
Of course I could do some text manipulation myself, tailor built for the widget I'm using, but that doesn't seem like the "right" solution (especially if I want to have the embedded text in some external file and not in the middle of my code as in the example above).
Can the above mentioned issue have a better solution than the one I thought about?
Is there an implementation of a news-feed widget in Haskell/Yesod that I can use as a plugin?
Note: I'm a very poor javascript programmer, but solutions in that direction are also welcomed.
Thanks,

How to change button layout and position in Threepenny GUI?

How do I change the size and position of buttons or other UI elements in a GUI created with the threepenny-gui package?
The documentation of Graphics.UI.Threepenny.Attributes lists some functions which are probably useful, such as coords :: WriteAttr Element String. However, I don't understand how to use them. Specifically, I don't understand what the String argument is supposed to be.
Thanks
I think my misunderstanding that I had was that my problem was not actually related to threepenny-gui but is instead a question about HTML. This link helped my find the answer I was looking for: https://www.geeksforgeeks.org/html-attributes/
Just in case anyone else is struggling with this as well, this line (mostly) solves it:
# set UI.style [("text-align", "center"),("color","red"),("font-size","30px")]
(The UI in UI.style comes from: import qualified Graphics.UI.Threepenny as UI)
Threepenny UI element combinators translate more or less directly to HTML, and so you should think in terms of HTML when doing layout with it:
The attributes from Graphics.UI.Threepenny.Attributes you mention are HTML attributes. Modifying them while defining your initial layout is typically done with set. (By the way, if you need a reference for looking up what things like HTML attributes do, you can't do wrong with MDN.)
For CSS styling, you can use the (#.) combinator.
As for layout, the basic tools are (#+) to nest HTML elements, and grid, row and column to arrange div-based grids.

Kentico Widgets :: Matching fields with HTML structure of Web Part

I really hope I'm making sense with this one.
I'm trying to create a widget from a custom webpart that I created. It's nothing special at all as you can see:
<h3>Header</h3>
<p>Intro Copy</p>
<ul>
<li>List item one</li>
<li>List item two</li>
<li>List item three</li>
</ul>
I now want to be able to create a widget from this and create new fields that will be used to populate the above DOM. What do I need to do in order or do this.
In an example I saw for the demo site, they populated the bg image with:
style="background-image: url('{% ResolveUrl(PathToImage) %}');"
That was however done on the front facing part of the CMS and I'm trying to do it within the solution.
Any thoughts?
It's all in your layout or code behind. Your layout can have that code (but in ASCX format) and it will work just fine. OR you can add literal controls to the page based on the fields and what the user has entered.
Doing it in your layout is more restrictive and specific to that one application but allows you to use multiple new webpart layouts. Using the code approach allows you to be more dynamic but doesn't allow you to use the built-in layouts of the webpart/widget.
I would just use the Transformable Web Part in the Marketplace...it does exactly what you want it to do. Create a custom web part, and you use a Transformation to style the Web Part Properties into the DOM elements.
https://devnet.kentico.com/marketplace/web-parts/transformable-web-part
Reason why i built it!
I've done something similar in the past, using what I call generic web parts. I wrote a blog on it last year - it might help out with what I think you're trying to achieve:
http://www.mattnield.co.uk/Posts/Show/generic_web_parts_for_rapid_development
Why are you choosing to go with Widgets? If you want to access any field inside the transformation within the web part it's feasible by the same way as you define in inbuilt web parts.
If you want to perform any function like onload etc. then you need to use kentico API to access any data.
If you provide more insight on what is required, I can help further

Stash : Conditional Content

First off, a caveat ... I am brand new to Stash. I've heard a lot about it but this is my first time actually playing with it. I get the concept, but am having a hard time figuring this one thing out.
I have a main "wrapper" file and everything within that wrapper stays the same. I would like the option however, to be able to toggle the sidebar on and off if I need to.
I wouldn't think I would need a totally separate layout wrapper would I?
Is there a way to use a boolean variable within stash? (e.g. 2col=TRUE) or am I thinking about it wrong?
Thanks in advance for your help!
Generally what I'd do here is setup multiple Stash gets within the wrapper. Then in your individual templates you can set both the sidebar and the main content area. For parts where you might be repeating content, like the opening and closing divs of a sidebar, you can always drop some snippets inside the stash.
You can also use exp:stash:not_empty [docs] to wrap around the div or container for your sidebar within the wrapper.
I usually use one wrapper for every template. It'll contain an {exp:stash:get name="content"} tag, like yours, which contains the only variable content within.
In my individual templates, I embed the wrapper at the beginning using a regular EE embed ie. {embed="includes/wrapper"}.
Then I stash the content to be inserted into the wrapper using the {exp:stash:set name="content"} tag.
This seems like what you're doing anyway.
If I want to conditionally show a sidebar, I might just pass a variable into the embed.
eg. {embed="includes/wrapper" show_sidebar="yes"}
In my wrapper I would do this:
{if embed:show_sidebar}
Sidebar stuff.
{/if}

jade / express - when to use or not to use layouts

I've just started developing in express and am new to Jade as well.
I'm having trouble deciding when it's appropriate to use layouts and when not to. I'm also having trouble deciding when it's appropriate to use something like blocks vs. partials.
Any help regarding this is truly appreciated. I'm a little lost.
It's mostly a matter of preference. If you are used to something like Wordpress where you have a concept of a header and footer that you include into pages than you might not like layouts. I personally only use layouts with content blocks because the non-layout way tends to cause more repetition.
As for partials vs blocks. You use a partial for items that you want to reuse on different pages. While a block is a chunk of html that will be replaced by child templates.
An example of a partial can be the html for a product. So you have a thumbnail, the title and a description of a product. You might use this partial while listing the products in a category. But you might also use this partial for rendering a list of search results.
An example of a partial can be a main layout that contains you header and your navigation and a content area. If you want to reuse this main layout on multiple pages you will extend this it and overwrite the block in the child templates.

Overriding Core Shapes - Orchard CMS

I currently have a Content Type called "News" which is very simple (No custom properties etc.). I am trying to style this Content type when it occurs on a page of a specific layout, in this case a "News" page.
So - I have the layout that a News page will inherit from (Layout-url-News.cshtml), however I cannot seem to get the Content to display or inherit from a template (I have tried creating alternates such as Zone-url-News.cshtml and Zone-Content-url-News.cshtml, however both result in having no content at all.)
I had create both of the mentioned alternates by hand, as Designer Tools was unable to generate an alternate (The relative virtual path 'Orchard.Core.Shapes.CoreShapes::Zone' is not allowed here)
Basically - I cannot figure out how to style the content found on a specific page, (Title, Tags, Date, Body) as the Content always seems to inheirit from the base shape.
If your point is to style content in a zone, u might find it easier to use css. The layout system makes it really easy to identify the elements your interested in styling by using css selectors.
for example
.aside1.news { ... }
That takes care of 80% of styling needs
Most of the remaining is taken care of by the placement.info file which allows you to indicate which fields and what order for contenttypes and viewstypes (summary and detail)
the remaining needs are address by overriding the contentitem.view.
But you seem to indicate that you want to set the style for a contenttype in a specific zone for a url. So... You have the same contentType in different zones at the same url? I cannot imagine what you are doing. :)
Long and short, it sounds like your focused on the zone but it might be more helpful to focus on the contenttype or better yet, css. I ran into the same thing with url alternates suggesting alternates that aren't valid. It seems weird that it suggests zone alternates. I don't think those those are allowed.
