Style guide inconsistencies

Overall observations

The guide has been made after the sketchs and only document them. It does not provide any actual guide-lines for building other pages.

The style guide is not adaptable to our framework (vuetify) as-is, thus we need to tune both the framework and the guide.

Hard CSS tuning might result in broken components.

Enum ordinal as bit position

enum Modifier {
	DEFAULT, PRIVATE, PROTECTED, PUBLIC, STATIC, FINAL
}

DEFAULT     ordinal: 0  bitmask: 2^0 = (int) 1

INGREDIENTS

Quenelles:

Ingredient	Quantity
Butter	120 gr
Flour	200 gr
Milk	75 cl
White fish	200 gr

int DOWNSTREAM_INIT = Integer.MIN_VALUE >>> 1
int UPSTREAM_INIT = Integer.MIN_VALUE >>> 2
int SUBSCRIPTION_LOCK = Integer.MIN_VALUE >>> 3

AtomicInteger contenders = new AtomicInteger(Integer.MIN_VALUE)

private boolean halfInit(int mask) {
    int c = contenders.getAndUpdate(v -> v < 0 ? v | mask : v);
    return c < 0 && (c & mask) == 0;

Helidon Stager Maven Plugin

The stager Maven plugin allows to stage a directory. This is somehow similar to the maven-assembly-plugin but more compact and specific to our needs.

<!-- Maven properties used below -->
<properties>
    <site.output.dir>${project.build.directory}/site</site.output.dir>
    <cname>helidon.io</cname>

CLI Extension

Separate modules to be forked by the cli to handle things that are too expensive to be bundled with native-image (e.g. "https").

It shall be invoked with java -jar and not require classpath, either self-contained code or a standalone JAR (e.g. shaded).

The JAR file is embedded as a resource in the native CLI binary.

NOTE: Proxy has to be propagated to the forked JVM properly.
