inspecting fuctions
What do people do for debugging functions given that echo() doesn't work
inside them?
I'd prefer not to stream debugging output into the return value of the
function.

It is available for functions in the nightly builds.
For some info, see:

There's still some todo:

ciao,
Torsten.
I break up the function into simpler parts and test them individually.
Sometimes, I do this through breaking it up into many smaller function, and
one function which puts it all together, sometimes I do it by commenting out
parts of the function temporarily for testing purposes.

I use this function to echo any part of an expression.
// Echo expression and return it
function echoit(x) = echo(x) x;
Before function echo was added I sometimes had to resort to translating
code into Python to debug it.

For those who are concerned about "libraries", could a Save option be included in OpenSCAD that has an "archive" feature that simply saves the target file and any referenced library, or subfile into a ZIP file(for example).
With gigabytes so cheap these days, this would not cost much??
No doubt over time, changes to the OpenSCAD IDEmight render any particular example 'broken' but at least anyone else coming along behind would have a complete snapshot of the original working design to begin with.
It would also make sharing OpenSCAD designs easier?
Cheers.

I first write the code as a module to debug it, then translate it into a
function. e.g.
module Arc(centre, radius, angle1, angle2, step = 10, dir=false) {
a1 = dir ? angle1 : angle2;
a2 = dir ? angle2 : angle1;
polygon([for (a = [a1 > a2 ? a1 - 360 : a1:step:a2]) [centre[0] +
radius * cos(a), centre[1] + radius * sin(a)]]);
}
function arc(centre, radius, angle1, angle2, dir = false, step = 10) =
let(a1 = dir ? angle1 : angle2)
let(a2 = dir ? angle2 : angle1)
[for (a = [a1 > a2 ? a1 - 360: a1:step:a2]) [centre[0] + radius *
cos(a), centre[1] + radius * sin(a)]];

on the downloads (http://www.openscad.org/downloads.html) I see a
2018.01.06 build, and I installed that on top of what I had. But it does
not seem to have echo() for functions.
Where do I go to grab a nightly build? The OS is 64 bit windows 7

You need to go into Preferences >> Features and enable the "echo
expression" feature.

You may need to go into Preferences->Features to enable it.

After enabling it works, thanks Doug / Torsten
