The #MastoPrompt for Sunday 13 July 2025 is:

#halogen

The poem or story can include the prompt word or be about the prompt word.

@ me, if you like, or just include the #MastoPrompt tag (to allow people to follow or filter their feeds), or keep your work to yourself - all the options are good as long as you're writing.

If you're including an image please do include alt-text if you’re able to.

Is there a way to have #PureScript call DOM functions on #Halogen elements?

It _feels_ like re-rendering to VDOM would be wasteful, and there's already an event that will be triggered by my DOM calls.

In particular, I'd like like to use the existing browser/DOM state for a textarea (or some other form elements) rather than having to write a component that mimics what the browser is doing.

But, maybe I'm overthinking it, for now.

And I've done Part-3. It's good to delete tons of notes I had accumulated and make them almost well-formed thoughts.

I'll likely make:
- a git template/demo repo of some sort
- some step-back post for the over-arching theme of how simple-approaches lead you far

Next in line: a rant about SQL (tutorials but there are some original sins), it's gonna be much shorter than the close to 8,000 words of text of the recent series.

How I architect my #purescript #halogen apps.

https://dicioccio.fr/how-i-write-purescript-apps.html

I had to cut at 5K words because I likely have 1K/2K more to say about cross-cutting concerns like logs and analytics and configs. So that will make another article another week. Then I'll made a final synthesis with less discussions and a template app.

tldr: love your map and contramap more
unsaid: love your applicative and divisible too

Preparing a blogpost about how I architect my #purescript #halogen apps. Wondering whether I should drop a massive article around 3,000-5,000 words or whether I try to split it in two or three chunks.

I got around to adding bounds-checking to my interactive lambda-calculus toy: https://bss03.gitlab.io/halogen-lambda/

I need to change the bounds-checking component to use an AST next.

Then, step-wise evaluation, if bounds-checking passes.

I really like the #purescript #halogen framework for SPAs.

What's the easiest way to put my #purescript #halogen application on my #apache website? Even better if I can easily install it as a sub-site?

My current method is barely remembered, haphazard, and also breaks as soon as I put it not at the root (can't find CSS / JS, I think?).

Alternatively, I'd also be open to using #gitlab pages; the main repository is already hosted there.
