How to run it locally
With a modern node installation available, just start it with
How to install it locally
If you haven't already got Node.js >= version 10, then go get it.
npm install -g mapscii
If you're on OSX, or get an error about file permissions, you may need to do
sudo npm install -g mapscii
In any of the supported Linux distros:
sudo snap install mapscii
(This snap is maintained by @nathanhaines)
This is pretty simple too.
- Arrows up, down, left, right to scroll around
- Press a or z to zoom in and out
- Press c to switch to block character mode
- Press q to quit
If your terminal supports mouse events you can drag the map and use your scroll wheel to zoom in and out.
