BOSL2 confusion
I tried to run this code
use <BOSL2/common.scad>
use <BOSL2/arrays.scad>
use <text_on.scad>
text = reverse("A long text example to wrap around a cylinder, possibly
for a few times.");
L = 4len(text);
maxang = 360L/(PI50);
spiral = [for(a=[0:-1:-maxang]) [25cos(a), 25sin(a), 10+30/maxanga]];
difference() {
cyl(d=50, h=50);
path_spread(spiral, len(text))
atext(text[$idx], size=5,
anchor=str("baseline",CENTER),orient=DOWN);
}
from here
https://github.com/revarbat/BOSL2/issues/81
At first, I was getting these errors:
WARNING: Ignoring unknown function 'str_join' in file
../../Users/jon/Documents/OpenSCAD/libraries/BOSL2/arrays.scad, line 459
WARNING: len() parameter could not be converted in file , line 6
WARNING: undefined operation (number * undefined) in file OpenSCAD, line 6
WARNING: undefined operation (number * undefined) in file OpenSCAD, line 7
WARNING: undefined operation (undefined / number) in file OpenSCAD, line 7
WARNING: undefined operation (-undefined) in file OpenSCAD, line 8
WARNING: Ignoring unknown module 'cyl' in file , line 10
WARNING: Ignoring unknown module 'path_spread' in file , line 11
Compiling design (CSG Products generation)...
I then downloaded the latest BOSL2 and discovered that common.scad was
missing from BOSL2 entirely.
At that point I gave up.
Any clues about what BOSL2 library to use and how to get the example to run?
Thanks!

I tried the text_on_cylinder.scad that came with the examples and it
failed with:
WARNING: undefined operation (number * undefined) in file
../text_on.scad, line 148

It hasn't been updated in 4 years, so it's probably a lost cause.
Also you need to include BOSL2/std.scad instead of BOSL2/common and
BOSL2/arrays.scad doesn't exist

I'm not sure what text_on_cylinder is, but I suggest that if you want
to write text on a cylinder that you use the path_text() module, which
is part of the current version of BOSL2, and which was ultimately the
final outcome from that issue. I don't recommend digging up code
fragments from old issues. The BOSL2 manual is actually rendered by
BOSL2 so if there is an example in the wiki then it proves that the
code works. As noted, you should start BOSL2 programs with
"include<BOSL2/std.scad>". The various other files are included
automatically by that single include.

See examples 4, 5 and 8 for text on a cylinder.
