XRB alternatives - Haml, Slim, and Hamlit

Building a syntax highlighting extension for VS Code
First of all, I like Slim. I like the beauty and cleanness of Slim templates, to me they are way more readable than regular ERB templates and I think they fit in the ruby/Rails ecosystem very well. Slim is a close cousin to Haml, without the ugly percent characters, haha. I've used Slim exclusively in my projects since about 2016.

Hamlet: A type-safe Haml template engine for Go
> I can't say what problem it is supposed to solve
"Haml accelerates and simplifies template creation" https://haml.info/
If you'd rather write raw HTML, keeping track of closing tags etc, then don't use HAML. No need to bash it because you personally feel it is ugly or unnecessary. FWIW I personally feel the exact opposite.
-
Any web frameworks that could compare to Symfony?
Personally, I'd recommend Maud if you don't need something with runtime reloading. Not only is it much faster, it implements a template language that is effectively the Rust-syntax equivalent to Slim or Haml using a procedural macro, so you get compile-time verification that your HTML output is well-formed.

Rux: A JSX-inspired way to render view components in Ruby
Does this support HAML-style syntax? We're 100% HAML-only for templating, whether normal Rails views or ViewComponent... https://github.com/haml/haml https://haml.info/ so going back to writing HTML or ERB feels like a huge downgrade.
-
Anyone from a Typescript/React background who tried out Rust for the 1st time?
For templating, Maud is fast, gives compile-time well-formedness guarantees, and outputs minified HTML by default as a side-effect of it being based on Rust macros. (It's of a similar design philosophy to Slim and Haml)
-
Why must closing tags in HTML and XML contain the name of the tag being closed, if the tag being closed can be determined by the order they were opened?
You don’t even need closing tags. Both Haml and Jade do away with closing tags altogether.
-
Goddamn this tastes like eternal suffering.
That looks awfully like HAML.
-
I taught the chat bot an alternative syntax for HTML, called HBML, basically just braces instead of tags... we are so screwed
Your HBML is similar to HAML - is it time for HCML? https://haml.info/

Guess what kind of project i am building currently
it's an HTML preprocessor called HAML

Build Load More Pagination with Pagy and Rails Hotwire
Now, let's dive into the pagination part of this post: setting up Pagy for handling pagination in our Rails application. If you haven't included the Pagy gem in your project, you'll need to add it manually. Here's how you can do it:
-
Pagination in Rails with Pagy gem
Several gems are available for pagination in Rails, but the Pagy gem is one of the most popular and efficient. It is a fast and lightweight library that provides a simple and flexible API. In this article, we’ll explore how to use it to implement pagination in Rails.

Rux: A JSX-inspired way to render view components in Ruby
> Am I understanding correctly that there’s a significant difference in performance between using a ViewComponent + a partial vs. a ViewComponent which renders html via a tag - from inside the component?
I don't think there will be much difference at all in everyday use, but some libraries that value performance don't avoid templates for that reason, Pagy for example.

Personally I omit them in my projects whenever we want to customise attributes, I hate seeing stuff like this in templates:

A powerful search feature with what Rails provides out of the box
The next step was about backporting the templates, adding Pagy gem for handling pagination and creating the controller. I was then able to show the listings with the models, but the filtering was not working.

The Ultimate Search for Rails - Episode 1
On the backend, we'll need a few tools. Apart from the classics (ActiveRecord scopes and the pg_search gem), you’ll see how the (yet officially unreleased but production-tested) all_futures gem, built by SR authors, will act as an ideal ephemeral object to temporarily store our filter params and host our search logic. Finally, we’ll use pagy for pagination duties.

Pagination and infinite scrolling with Rails and the Hotwire stack
In our application, we will use Pagy to implement pagination. Let’s install Pagy now, following along with the Pagy quick start guide.

Load More Pagination in Rails with Hotwire Turbo Streams
For pagination I tend not to use gems like pagy or kaminari, instead implement this functionality just using limit and offset.

Ten Ruby gems for Rails you should definitely know about
Kaminari hooks onto ActiveRecord associations and makes it super easy to page them. Pagy is another option that seems to have a solid API but I haven't tried it yet.

Re-Wheel series part 1 - How does Rails' find_each work?
But how is this implemented? Well, if you use pagination in your index methods with gems like pagy, kaminari or will_paginate you will find that the same idea is happening here, they are using the power of SQL's LIMIT and OFFSET to fetch only a portion of the data each time. So in the 1 million users example, find_each will perform 1000 thousand queries with a limit of 1000 while changing the offset properly so we don't miss any record.
