Some commands work both in and out of a docker container

Convert to PNG ✅ openscad /dev/null -o "/data/CAD/$filename.png" -D "import(\"/data/CAD/$filename\");" --imgsize=600,600 --camera=0,0,0,45,0,50,25 --autocenter --viewall

✅ docker run --rm -v $(PWD):/data spuder/openscad:latest openscad /dev/null -o "/data/CAD/$filename.png" -D "import(\"/data/CAD/$filename\");" --imgsize=600,600 --camera=0,0,0,45,0,50,25 --autocenter --viewall

---

Convert to GIF ✅ openscad /dev/null -D '$vpt = [0,0,0];' -D '$vpd = 20; $vpr = [0,$t * 360,0];' -o 'foo.png' -D 'cube([2,3,4]);' --imgsize=250,250 --animate=360 --colorscheme 'Tomorrow Night'

✅ openscad /dev/null -D '$vpt = [0,0,0];' -D '$vpd = 20; $vpr = [0,$t * 360,0];' -o 'foo.png' -D 'cube([2,3,4]);' --imgsize=250,250 --animate 360 --colorscheme "Tomorrow Night"

✅ openscad /dev/null -D '$vpt = [0,0,0];' -D '$vpd = 20;' -D '$vpr = [0,$t * 360,0];' -o foo.png -D "cube([2,3,4]);" --imgsize=250,250 --animate 360 --colorscheme "Tomorrow Night"

✅ /Applications/OpenSCAD.app/Contents/MacOS/OpenSCAD /dev/null -D '$vpr = [60, 0, 360 * $t];' -o "${MYTMPDIR}/foo.png" -D "import(\"$file\");" --imgsize=300,300 --animate 60 --colorscheme "Tomorrow Night" --viewall --autocenter

❌ docker run --rm -v $(PWD):/data spuder/openscad:latest openscad /dev/null -D '$vpt = [0,0,0];' -D '$vpd = 20; $vpr = [0,$t * 360,0];' -o 'foo.png' -D 'cube([2,3,4]);' --imgsize=250,250 --animate=360 --colorscheme 'Tomorrow Night'

The docker for PNG works, but the docker for --animate fails

docker run --rm -v $(PWD):/data spuder/openscad:latest openscad /dev/null -D '$vpt = [0,0,0];' -D '$vpd = 20; $vpr = [0,$t * 360,0];' -o 'foo.png' -D 'cube([2,3,4]);' --imgsize=250,250 --animate=360 --colorscheme 'Tomorrow Night'

Theories

• Doesn't like $
• Doesn't like single quotes
• Doesn't like multiple -D options
• Doesn't like -- arguments that are missing =.
• Doesn't have a /dev/null in docker container (then why does png work)

Same version of openscad on my mac and in the docker container

 openscad --version
OpenSCAD version 2021.01

docker run --rm spuder/openscad:latest openscad --version
OpenSCAD version 2021.01

I suspect quotes are getting stripped in the exec statement

Executing /OpenSCAD.AppImage --appimage-extract-and-run /dev/null -D $vpt = [0,0,0]; -D $vpd = 20; $vpr = [0,$t * 360,0]; -o foo.png -D cube([2,3,4]); --imgsize=250,250 --colorscheme Tomorrow Night
