@julian there's no difference on the consuming side (and in many programming languages you can check for truthiness with something like `if x.get("totalItems")` which defaults to returning null if missing anyway)
functionally, you either have the information, or you don't
trwnh@mastodon.social as someone working on the consuming side, that is not correct.
If my AP lib automatically assumed null when requesting an object property that didn't exist I'd consider that a bug.
-
@julian this wouldn't be your AP lib, it would be your programming language itself

trwnh@mastodon.social I'm coding in js, which has all sorts of footguns, but even that won't return null when I attempt to access the non-existent property of an object... 😛

@julian what does js return instead? in most cases i'm familiar with, programming languages use null or nil or None for anything that doesn't have a value, or any reference which doesn't point anywhere. hence a null pointer exception when you try to dereference a null. if you try to get a value for a key that isn't in the dictionary, you get null by default because there is no value for a missing key. how would you consume a null value? if you have nothing to say, why say anything?

undefinedand perhaps that's why we're disagreeing on our interpretations of how these values should be handled.nullin JavaScript is very explicitly a declaration that there is no value or "intentionally empty".nullandundefinedare two separate things here at least. -
@julian that might be it, yeah. languages outside of javascript generally don't make a distinction between null and undefined, and even in javascript these are used inconsistently. for example localStorage.getItem will return null for a missing key. practically speaking, the "intentionally" distinction is a distinction without a difference in most processing contexts.

@silverpill
Yep! Just was on vacation and had a conference to do. It's on my list for Monday to do some followup and updates

@toddsundsted ok, bookmarked. When I'll circle back to ONI themeing I'll send some feedback your way to compare notes. :D
With ONI I tried to be "fun" and I generate a basic palette from the images actors upload as their Icon and Image properties (ie, profile and header picture in mastodon terms :D) As you can imagine that can lead to very dubious results.

@mariusor no, i'm still trying to figure that out myself. what i have done is build something that seems capable of handling themes that i find that i like. but even there i guess i have ~2-3 more revisions before it is fully capable.
i did pick semantic ui as my base framework. it has worked well, but it is abandoned. there is a fork called fomantic ui that is supported, but it is also much larger. other frameworks also seemed too large for my tastes, but i will admit to not doing a ton of research.
-
@toddsundsted did you use any literature for deciding on the theme basic colors and how to combine them?
I've been struggling with something very similar a while back and the material design specs seemed too complex for what I wanted, but nothing else popped up on search.

I've streamlined theme development in Ktistec. The theming system uses a hierarchy of CSS custom properties and fallbacks. Theme authors can customize a theme at multiple levels:
Base Colors Only
Define only base colors like --text-primary, --bg-primary, --bg-input, --semantic-primary, etc. Derived colors will auto-generate using color-mix formulas. For example:
:root { --semantic-primary: #ffa500; }From this one line, theme-appropriate colors like --bg-accent-code, --anchor-color, etc. auto-generate.
Base Colors Plus Derived Colors
Define base colors and derived colors. Derived colors use custom values when defined. Undefined derived colors auto-generate. For example:
:root { --text-primary: #333; --text-primary-2: #ff0000; /* red for this specific shade */ }Given this theme, derived shades like --text-primary-1, --text-primary-3, and --text-primary-4 auto-generate. --text-primary-2 is red.
The simplest possible interesting theme redefines the primary semantic color. The single line above (in Base Colors Only) would result in the following, with button color, link color, disabled, selected, and hover states all derived automatically:

@tofeo take a look at https://gitlab.com/edent/activity-bot/-/blob/main/README_nginx.md?ref_type=heads
I don't use nginx, but that should help.

I discover your onepage activitypub application at https://shkspr.mobi/blog/2024/02/activitypub-server-in-a-single-file/
It is really a good start for me
But how would you adapt it with Ngnix server
All the logic is based on .htaccess but in Nginx it leads with all 404 pages
