I haven’t seen "" or a disconnected path before. Also, we do have a strange artifact, at least when I run this code. There is a line running across Brazil: I only got the line for (23,0), not for other latitude and longitude. I’m not sure what caused that. The code for cutting and mending paths that cross the horizon is tricky. I’m not sure how it will interact with "" and “cycle" connecting everything.

[NTG-context] Seeking advice for module that draws globes
Hello ConTeXters, I wrote a little ConTeXt module for drawing globes. I would love some advice on how to improve it and share it. The code is quite short (about 250 lines). Most of the work is done by Lua, which reads the data files and calculates paths. These paths are passed to MetaFun, which draws the globe. Below is an example document with the output. (I attached a small .png of the output for the mailing list. The output PDF has excessive detail.) The module (code and data) is on GitHub at https://github.com/GavinPolhemus/luageo. \usemodule [luageo] \startMPpage GlobeDiameter = 10cm ; fill fullcircle scaled GlobeDiameter withcolor .9white ; % Fill a circle with the water color. drawglobe(23, 0) scaled GlobeDiameter withcolor .75white ;% Draw the land, centered on the given latitude and longitude. draw fullcircle scaled GlobeDiameter withcolor black ;% Add a border, if you want. \stopMPpage I am a novice at both Lua and MetaPost.

Thanks for this solution.
Is there also something for inline-mode? Example:
test \beginH TEST\endH test
You can create different versions of your environment and let context choose
one whether the mode is enabled or disabled.
