I am trying to use a hashmap that will work in both OpenSCAD and PythonSCAD, but I keep getting errors that the function is not found. Has anyone had success in calling OpenSCAD code from PythonSCAD, which includes a hashmap? A snippet of the code is as follows: OpenSCAD: /////////////// Color_Table = hashmap(items=[ // the laser color parameters (name,power,feed,color) ["L00",[1.0,1.0,0x000000]], ["L01",[1.0,1.0,0x0000FF]], ["L02",[1.0,1.0,0xFF0000]], ["L29",[1.0,1.0,0xFFDB66]], ["T1",[0.0,0.0,0xF36926]], ["T2",[0.0,0.0,0x0C96D9]] ] ); function Color_Table_to_color(name) = Color_Table[name][2]; /////////////// I have also tried making the color table a function (function Color_Table() = ...) Any suggestions?

OpenSCAD proper does not have a hashmap() function and does not have anything called a "hashmap".  It does have objects, which are probably similar: Color_Table = object([ // the laser color parameters (name,power,feed,color) ["L00",[1.0,1.0,0x000000]], ["L01",[1.0,1.0,0x0000FF]], ["L02",[1.0,1.0,0xFF0000]], ["L29",[1.0,1.0,0xFFDB66]], ["T1",[0.0,0.0,0xF36926]], ["T2",[0.0,0.0,0x0C96D9]] ]); I have no idea whether obejcts are integrated into PythonSCAD, or whether PythonSCAD exports a hashmap() function into OpenSCAD.

I've used hashmaps with BOSL2 in the past, but thought hm was part of the OpenSCAD primitives. That is why I tried it. I just tried your object code, and it failed as well. I'll keep looking for similar functionality that works for both code bases. Thank you!

you can use search() to treat a vector of key vaue pairs as a map. object() is in the dev builds only at this time. https://en.wikibooks.org/wiki/OpenSCAD_User_Manual/Other_Language_Features#search On Wed, Feb 11, 2026, 21:27 John David via Discuss < discuss@lists.openscad.org> wrote: > I've used hashmaps with BOSL2 in the past, but thought hm was part of the > OpenSCAD primitives.

I have no idea whether it integrates with PythonSCAD. It definitely works in OpenSCAD development snapshots, but it is considered an "experimental" feature and so you must enable it using Preferences/Features.

In PythonSCAD you can leverage all features which comes with python, So also hashes(python dicts) This sample works: hash.py: def colorhash(key): Color_Table ={ "L00": [1.0,1.0,0x000000], "L01":[1.0,1.0,0x0000FF], "L02":[1.0,1.0,0xFF0000], "L29":[1.0,1.0,0xFFDB66], "T1":[0.0,0.0,0xF36926], "T2":[0.0,0.0,0x0C96D9]} return Color_Table[key] hash.scad: use <hash.py> echo(colorhash("L02")); PythonSCAD aims to be 100% openscad compatible. so I has OpenSCAD objects, but Python dicts are powerful anyway. Look into hash.scad and see the ease how to export python functions ito SCAD code.

Sorry I did not see this before I spent a lot of time messing from the OpenSCAD side today. I'll go back and give the python to openscad side a try. BTW, I got something similar to this working from pure OpenSCAD, but the colorhash is immutable and I was planning to allow the user to be able to set the power and feeds associated with the colormap. Anyway, I'll give the python-first a try later.

BTW, I am getting the error " Parsing design (AST generation)... ERROR: File not trusted '/home/ebo/.local/share/OpenSCAD/libraries/tabbed-box/colormap.py' Any idea how to turn that off?

yes, of course, just launch PythonSCAD with --trust-python many folks actually install this option into the desktop symbol ...

Figured it out. hash.py need "from openscad import *" to run. Now it does.
