Draw line in gimp with macro

Question

I have calculated a set of lines to be drawn onto the image I calculated the geometry from. I was hoping for a macro recorder so I could just hack my geometry calculating program to spit out something similar. All I need is example code that just draws a line from literal constants that I can just embed in a batch job. I can handle having to just cut and paste that into the script fu window. It's a fire once macro.

There is no "macro recorder" in Gimp, you have to write scripts.

You can create a "path" from a CSV using this script (for straight lines, the coordinates of "tangents" are the same as those of their anchor) and then use Edit > Stroke path (in "Line" mode) to render the lines.
