There has been a lot of discussion about summing up something in OpenSCAD. Wouldn't it be worth to add feature request for a sum(list) primitive to OpenSCAD? Especially newbies, who aren't running their own libs or writing functions, would appreciate this. Not having a sum(), is like not having a len() function and having to implement it on your own: echo(len([1,2,3, 7])); function len(X=[],i=0) = X[i]== undef?0:1+len(X,i+1); I mean we have functions like cross(), norm(), abs(), min(), max(), floor(), ceil(), sign(), sqrt() - to name the most prominent ones - which could all be implemented by the users as well, so why is sum() missing? Personally I also wouldn't be unhappy with a basic set of file functions, like fopen(), fecho(), to eventually leave the medieval darkness OpenSCAD is self-restricting itself ;-) -- Sent from: http://forum.openscad.org/

I am in favour of sum, and some sort of file io. It would be nice to be able to add users pace support for new file formats. The fopen/fread/fwrite/fclose/ftell/fseek set is complete, at least On Thu, 25 Jun 2020, 09:08 Parkinbot, <rudolf@digitaldocument.de> wrote: > There has been a lot of discussion about summing up something in OpenSCAD. > Wouldn't it be worth to add feature request for a sum(list) primitive to > OpenSCAD?
