I'm calculating large-ish arrays in openscad to pass on to another program
and I cannot capture more than 1024 characters.

"openscad.com -o dummy.stl somescript.scad" works and dumps the entire
contents on the command line.

"openscad.com -o dummy.stl somescript.scad | more" will show a truncated
result.

"openscad.com -o dummy.stl somescript.scad > out.txt" will result in a
"out.txt" file with only 1024 characters.

The output of "more" ends with the same character as "out.txt".

Any idea what may be wrong ? Is there maybe a missing flush ?

Cheers, Ivo

I presume this is echo() output?
If so, from the  wiki
https://en.wikibooks.org/wiki/OpenSCAD_User_Manual/Using_OpenSCAD_in_a_command_line_environment
, "For at least 2015.03-2+, specifying the extension .echo causes openscad
to produce a text file containing error messages and the output of all
echo() calls in filename as they would appear in the console window visible
in the GUI. Multiple output files are not supported, so using this option
you cannot also obtain the model that would have normally been generated."

Also, I seem to recall something about things going to STDERR, so try '2>'
(see  this
https://support.microsoft.com/en-au/help/110930/redirecting-error-messages-from-command-prompt-stderr-stdout
)

This script :
a = "0123456789";

module b()
{
echo(a,a,a,a,a);
echo(a,a,a,a,a);
echo(a,a,a,a,a);
echo(a,a,a,a,a);
echo(a,a,a,a,a);
}

module c()
{
b();
b();
b();
b();
b();
}

c();

called with "openscad.com -o dummy.stl echobug.scad | more" produces

ECHO: "0123456789", "0123456789", "0123456789", "0123456789", "0123456789"
ECHO: "0123456789", "0123456789", "0123456789", "0123456789", "0123456789"
.. more of these ..
ECHO: "0123456789", "0123456789", "0123456789", "0123456789", "0123456789"
ECHO: "0123456789", "0123456789", "0

note the truncated end.

Without redirection "openscad.com -o dummy.stl echobug.scad" produces the
correct result  on the commandline.

The captured result is truncated at 1024 characters. Adding "2>&1" doesn't
matter, it's not STDERR that i'm missing. Capturing does not work on the cmd
commandline or in powershell.

openscad.com -version
OpenSCAD version 2018.01.06

I'm convinced this is a bug.

Hints, tips or work around-s would be greatly appreciated.

I'd like to use a two stage script, one calculates an array, the second uses
the elements of the array to multmatrix objects to their correct location.
The generated objects are merged outside of openscad to avoid the implicit
union.

Cheers, Ivo

Did you try:
openscad.com -o output.echo echobug.scad
