sic transit gloria carto

the CartoCSS style language repository (used on default map on OSM.org) has been archived by #Mapbox
#OpenStreetMap #Carto #CartoCSS

It's worrying that most of the styles used for #openstreetmap tiles are based on #cartocss, which is archived. The last commit was 4 years ago.

@dcz property-wise, #cartocss is a thin layer on top of #mapnik XML:

As for the operators, check:

Make sure you read the examples, because it has more types of expressions that are not defined elsewhere, I think.

Finally #OSM 's style has more examples, but it might be tedious to read them all:

@nickbearman Working on a #QGIS plugin to style maps using #CartoCSS. Clicking through style dialogs gets annoying fast.
"From 2019, the #cartographic style #OpenArdenneMap is updated every 6 months. OpenArdenneMap is a cartographic style for topographic maps based on #OSM data.OpenArdenneMap was originally developed as a cartographic style with the #imposm importer and a #cartoCSS style derived from #OSMBright. Later the #osm2pgsqlimporter was used instead of the imposm. From 2023, the OpenArdenneMap is also available in #QGIS"

Before I set out on the latest #cycling trip, I wanted to print a road map with more focus on peaceful ways, and less on busy highways.

My previous attempts usually failed, but this time I found TileMill.

https://tilemill-project.github.io/tilemill/

It's easy to install (in comparison to Mapnik) and it's designed for writing custom styles. In just an hour or two I went from zero to a useful style!
