Êrthur is a dfhack tool that exports a full map of the world based on the embark screen, and makes it zoomable/pannable like Google Maps.

Here's an example!

I created this because I couldn't find any existing tool that did it, and I wanted a full-size world map using the same characters and colors as the embark screen, rather than using a single pixel per tile like the exported detailed map from legends mode. It's very much WIP, but it's working well for me. If others are interested in this tool I'd be happy to clean it up and make it more user-friendly!

The code is available on GitHub.

Awesome! This could finally be the utility that streamlines hunting for certain embarks. However, is there a way to export a world-map sized relative heightmap that you can access during embark? Or the cliff indicator display?

[nornagon]

Hm... it might be possible but it'll be a bit of a different approach, because the relative heightmap changes scale as you move across the map in the embark UI. I tried it, and here's what I got:

Pretty, but not especially useful.

I think you could theoretically generate a global heightmap that uses the same color scale and characters as the relative heightmap in-game, but generate it based on the exported full heightmap that you can get from the game already, rather than what Êrthur does, which is pan across the embark map and pull characters off the screen.


It works OK for cliffs, though, since they're consistent across the map:

Seems neat, but I ran into errors after running `node draw.js`

Parsing map...

Drawing chunk 0,0...
Writing chunk 4,0,0...
(node:23870) UnhandledPromiseRejectionWarning: Error: ENOENT: no such file or directory, mkdir '/path/to/df_linux/erthur/tiles/4/0'

Should there be mkdir -p instead of just mkdir, or something?

[xzaxza]

Also, installing 98 MiB of module dependencies is bit funny, but I guess that's nodejs for you.

Anyway, I did `mkdir -p tiles/4` and after that it ran a bit further, this time exiting like this:

Aand looks like I fixed it by adding this to the beginning:

Code: [Select]

const mkdirp = require('mkdirp')
and then replacing

Code: [Select]

fs.mkdirSync(outDir, {recursive: true})
with

Code: [Select]

mkdirp.sync(outDir)

@xzaxza, thanks for the debugging! Feel like opening a PR on GitHub? I guess this is a windows/mac difference, as the code works fine on my mac.
