It runs on GNU/Linux and on Windows (MSYS2/MinGW) and requires Lua (>=5.3) and Assimp (>=3.0).

Setup the build environment as described here, then:
$ git clone https://github.com/stetre/moonassimp
$ cd moonassimp
moonassimp$ make
moonassimp$ make install # or 'sudo make install' (Ubuntu)The script below loads a scene from a 3D model file and prints the names of all the nodes it contains:
-- MoonAssimp example: printnodenames.lua
ai = require("moonassimp")
filename = arg[1]
if not filename then print("Usage: " .. arg[0] .. " <modelfile>") return end
function print_node_names(node, indent) -- recursively prints the names of child nodes
local indent = indent or " "
for _, child in ipairs(node:children()) do
print(indent .. (child:name() or "???"))
print_node_names(child, indent .. " ")
end
end
-- Import the scene from the model file:
scene, errmsg = ai.import_file(filename, "triangulate", "join identical vertices", "sort by p type")
-- Check that nothing went wrong:
assert(scene, errmsg)
-- Get the root node and print the names of the nodes:
root = scene:root_node()
print(root:name())
print_node_names(root)
The script can be executed at the shell prompt with the standard Lua interpreter, passing it a 3D model filename, e.g.:
$ lua printnodenames.lua mymodel.daeOther examples can be found in the examples/ directory.
