@nekoinemo Ignore what I said. I see what you're doing. It looks good, but I'd recommend sticking to the names I used (

child

,

contains

,

next

, and

sibling

). Not because they are better (in fact, I think I like the way you did it better; no reason to have multiple names for the same thing), but because those are the names for those functions we use elsewhere, and it should be consistent. Maybe we can look at renaming them when we do the whole CSS rewrite.

I apologize for how hairy the code is in there. I had only been using Kotlin for a month or two when I wrote most of the CSS stuff. Yet another reason it should be rewritten 🙂

@nekoinemo Thanks for the PR! I'll leave it up to @Ruckus to evaluate it, the CSS is not strong with me 🙂 hehe

@Torbilicious If you want to load the SVGIcon content from an external URL, you can do

URL("").readText()

, but if the resource is available on the classpath, you can do

SVGIcon(resources.text("/path/to/iconm"))

yeah, the general decline in funding for javafx is pretty sad. it's frustrating too because they ignored and fluffed deployment for so long. if they had done a better job on deployment, jfx could be far more popular

and that in turn would ensure further funding

fortunately it's a pretty mature framework

no1 priority for java client now (and really all desktop clients) cross platform app browser that works really, really well

@mikehearn what do yo mean when you say "app browser"?

auto-maximised JavaFX window with a tabpane at the top, which classloads modules from remote web servers and initiates them with a Scene that's embedded in the tab using SubScene

locally cached module files, with AppCDS and in future AOT files being generated automatically in the background for faster startup

some basic bookmarking functionality, gallery functionality or other way to start an app (maybe a URL bar that only takes domain names .... URL bars are the worst part of browser UX by far)

app browser auto upgrades itself in the background a la Chrome and handles online/offline use properly.

basically a container for GUI apps that knows how to silently and rapidly auto-upgrade apps that use it

a bit like Web Start but with a fresh start. none of the million and one security prompts, crap JRE installer, slow blocking upgrades and so on

possibly even a mode in which FXML + CSS is downloaded first, with the code that backs it coming afterwards, like the web does it

i've written some stuff about these ideas before. Java already has most of the features needed. It's about tying them up in a nice bow, with a browser style UX that users are familiar with (but it doesn't need, imo, to be a real web browser). register a URL handler that opens up the new tabs and off you go.

think of it as Steam for Java

@mikehearn have you used the commercial JxBrowser? it has pretty good chromium.exe cross-platform support

It's amazing how quickly nested compound selectors can blow up. I was testing @nekoinemo's PR, and this:

s(a, b) {
    and(c, d) {
        child(e, f) {
            next(g, h) {
                sibling(i) {
                    fill = c("red")
                }
            }
        }
    }
}

becomes this monstrosity:

.a.c > .e + .g ~ .i, .a.c > .e + .h ~ .i, .a.c > .f + .g ~ .i, .a.c > .f + .h ~ .i, .a.d > .e + .g ~ .i, .a.d > .e + .h ~ .i, .a.d > .f + .g ~ .i, .a.d > .f + .h ~ .i, .b.c > .e + .g ~ .i, .b.c > .e + .h ~ .i, .b.c > .f + .g ~ .i, .b.c > .f + .h ~ .i, .b.d > .e + .g ~ .i, .b.d > .e + .h ~ .i, .b.d > .f + .g ~ .i, .b.d > .f + .h ~ .i {
    -fx-fill: rgba(255, 0, 0, 1);
}

But it looks right...

@carlw nope, not used JxBrowser.

@Ruckus maybe @thomasnield’s next blog post can be on CSS Algebra ?

@mikehearn thanks for describing the concept. I could see something like that being extremely useful in an enterprise environment.

Hey @mikehearn I really like that idea, can you share the links about your write ups regarding that topic... We probably start a github project some time down the line so people can gather ideas and build a prototype?

@Ruckus Haha, that's pretty hard to verify just by looking at it!

It took me a bit to reason through it 🙂

@nekoinemo Thanks for the PR. It's a great addition to the project.

I can't say i'm into CSS, but i'm toying around with CSS for my pet project at the moment, so i just might 🙃

@nimakro this channel would be a great place to coordinate such a project
