# Der Kartograph Map Generator
Generate your own maps for "Der Kartograph" easily.
## Build
You need to build the source first. The simplest way is to use the
provided Dockerfile, which will build the software and create a
convenient image (This is a multi stage Dockerfile, so the resulting
image is a small Alpine Linux image with ust the map generator binary.)
$ docker build -t kartograph .
## Run
See all available options:
$ docker run -it kartograph -help
Spawn a webserver:
$ docker run -it kartograph -web
Generate a map with the seed "hey jim" and output it as a SVG image:
$ docker run -it kartograph -output=svg -seed='hey jim' > map.svg
You want an epic game? Lets generate a big map with a lot of wasteland
and ruins:
$ docker run -it kartograph -seed=aaron \
-size=20 -wastelands=100 -ruins=10 \
-output=svg > map.svg
