GEOS geometry library for Nim

Nim bindings to GEOS geometry library generated by nimterop.

Requirements

Install GEOS library to your system. Check your package manager for available version.

sudo apt install libgeos-3.9.0

Usage

import geos

var context = GEOS_init_r()
var writer = GEOSWKTWriter_create_r(context)
GEOSWKTWriter_setRoundingPrecision_r(context, writer, 3)

var geometry = GEOSGeom_createPointFromXY_r(context, 1, 2)
echo GEOSWKTWriter_write_r(context, writer, geometry) # "POINT (1.000 2.000)"

GEOSWKTWriter_destroy_r(context, writer)
GEOS_finish_r(context)

Rebuild

# get headers
sudo apt install libgeos-dev
nimble install nimterop
./generate-nim-binding.sh

This copies GEOS header file to lib directory with some modifications. Then generates nim library into src directory and runs tests.
