Hi Jörg,
I also had this same thought and it would be a good mechanism.
But I solved it with my own preprocessing.
I have been doing Nautical charts with Mapserver for a
couple of years and realized that I was reusing
the same layers up to 18 times.
So I did templates where I had LAYER->NAME, LAYER->GROUP,
LAYER->DATA and STYLE->COLOR as variables in Mapserver templates.
Color for instance has fixed names like “DEPVS”,
that means depth very shallow.
But depending on if it is day mode, dawn dusk mode or night mode
the colors have different rgb or hex values.
All variables are stored in csv files. The variables are read into
associative arrays in a bash script. Then I use my Mapserver
mapfile templates that are processed with a very long sed statement
that substitutes the variables depending on color mode and scale level.
Layer names and groups have one csv file that tells how to
assemble all the layers. To make it even more flexible, I can
also use offical IHO colors, Swedish or French color tables
to get different look and feel.
An example is for instance the layer template for rivers:
#### Rivers Lines ####
LAYER
NAME "Rivers_line_{CL}"
GROUP "{GROUP}"
METADATA
"ows_title" "Rivers"
"ows_enable_request" "*"
"gml_include_items" "all"
"wms_feature_mime_type" "text/html"
END
TEMPLATE blank.html
TYPE LINE
STATUS ON
MAXSCALEDENOM {MAXSCALE}
DATA "{PATH}"
CLASS
NAME "Rivers (lines)"
STYLE
# DEPVS
# RGB # COLOR {DEPVS_rgb}
COLOR "{DEPVS}"
WIDTH 1.5
# RGB # COLOR {OUTLL_rgb}
OUTLINECOLOR "{OUTLL}"
OUTLINEWIDTH 0.3
END
END
END
All this can be seen in the git hub: https://github.com/LarsSchy/SMAC-M
I finally got permission from my company to release it this summer, so that we
can discuss this.
I would like to do a demo site with open data, but haven't had time to do this
yet.
The script: process_layer_color.sh shows the real processing part and the sed
script.

Have fun
