[Geoserver-users] Variable substitution in CSS styling?

I’d like to declare variables, and use them later on in the styles - something like

/* Declare color scheme */
@primary: #E4E4E4
(…other declarations…)

[highway=‘primary’]

[@scale < 15000000][@scale > 1600000] {
stroke: @primary
(…)
}

[highway=‘primary’]
[@scale < 1600000][@scale > 80000] {
stroke: @primary
(…)
}

[highway=‘primary’]
[@scale < 80000][@scale > 4000] {
stroke: @primary
(…)
}

I realize in this specific case cascading would cover my use case, but there are use cases where cascading doesn’t work, but I still want to maintain a reference. (Color palette’s are my use case for this - though there may be others).

I use this in CartoCSS all the time - just trying to find a good analogue in GeoServer’s CSS.

I'm afraid there is no such equivalent, at least at the time of writing,
althought this would be of course a
welcomed improvement
