batch processing commands
I want to process a list of .scad files in a folder, and i didn't understand
how to do it with command line, please could someone tell me the secret
codes?

The simplest of commands for one file would be:
openscad -o file.stl file.scad
You could repeat this using whatever looping construct is available in
your shell. (For windows, it's been so long I can't remember the
syntax.) For bash, you could do
for f in *.scad; do openscad -o ${f/scad/stl} $f; done
Personally, I use a Makefile with an appropriate rule for converting
any .scad file into a .stl.
%.stl: %.scad
$(OPENSCAD) -o $@ $<

Thanks, i will figure it out and i will write it on the wiki if i can.

If it helps, equivalent in a Windows batch fiile is :
for %%f in (*.scad) do echo openscad -o %%~nf.stl %%f

That should be
for %%f in (*.scad) do openscad -o %%~nf.stl %%f
of course.

oh my god awesome. i will write that to the wiki and to various resources. i
was going to take at least an hour of learning a new code to find that line

I'll change to a new email soon, save from the pop routing errors.
in the end i had a .bat file with text:
for %%f in (*.scad) do openscad -o %%~nf.stl %%f
written in it, and i had to set the PATH using this else it didnt recognize
openscad:
*** GUIDE FOR SETTING WINDOWS PATH ENTRIES FOR CMD.EXE:***
Start the System Control Panel applet (Start - Settings - Control Panel -
System).
Select the Advanced tab.
Click the Environment Variables button.
Under System Variables, select Path, then click Edit.
You'll see a list of folders, as this example for my system shows:
C:\Program Files\Windows Resource
Kits\Tools;%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;C:\Program
Files\Support Tools;C:\Program Files\Common Files\Roxio
Shared\DLLShared;C:\Program Files\Common Files\Ulead Systems\MPEG;C:\Program
Files\Intel\DMIX;C:\Program Files\Executive Software\Diskeeper;C:\Program
Files\Bonjour;C:\Program Files\QuickTime\QTSystem;C:\Program Files\Misc
You can add additional folders that you want to include in searches. I add a
"C:\program files\misc" entry into which I place my standalone utilities,
instead of copying them into C:\windows. Click OK.
You'll need to restart the processes (e.g., command prompt) that use the
system path to see the added folders.

I ran the command on some files from kit wallace's website for a test and
about 1/3rd of the .scad files were processed.
So i ran it on a couple of dozen of my .scad files and only 1/20 files was
processed. If i run the program without the -o command, it opens 20 windows
at once, all of them have empty code windows except for one of them that had
one line of code in it.

ok it seems like it's working although perhaps it's not totally there, here
is what i did:
had to rename all the files with spaces " " to "_" because cmd.exe didn't
see them,
to do that:
1/ run powershell.exe from system3d/windowspowershell or just the run
console
2/ type cd "D:\my dir\batch dir"
3/ do this powershell command: Dir | Rename-Item –NewName { $.name
–replace “ “,”” }
4/ then run the script from a .bat file... FOR %%f in (*.scad) DO openscad
-o %%_nf.stl %%f
we can also write batch files from powershell for windows it's the new
cmd.exe since 2009 it has more flexibility and more ledgible, but it's still
an entirely new code so only for those who want to learn powershell syntax.

You can put file names in double quotes for spaces and the like,
but I strongly recommend make.

the files would be in a double quotes with a wild card in the current
directory, i don't know if i can write "%THIS_DIR%*.scad" kind of directory
so that the batch file can run on any pc and be a portable windows option
for batch processing scads, for others too, that's the intention. anyways it
works, will see if cmd.exe crashes after 10 files or something, quite
possible. i am after a one click solution for others and myself, not
learning powershell, batch, and makefile just so that i can make my slow
scad files :)

Better to use Python than shell scripts as they are simpler and more
readable and run on any OS.

No need to rename files, just use:
FOR %%f in (*.scad) DO openscad -o "%%_nf.stl" "%%f"
make and python are great if you already have them installed, but overkill
in this case.

make intended to save time and it may really save lot of time in some

Yes, although that only works if make knows about all the dependencies.
Otherwise a simple Makefile will only work when changing the top level
scad file.
In theory OpenSCAD can write the dependency information to make it work
in the general case, but I've never tried that yet.
ciao,
Torsten.
I used to write dependencies manually :-)

Could you describe your new workflow with batch processing Tim? I have been
busy with complicated projects in OpenSCAD and have come up with a workflow
that makes sense to me, but I am keen to learn any real programmers' best
practice.
I currently have a split like this:
- Library files I use all the time in 3 groups:
SCAD I have made
SCAD I have borrowed from others :)
STLS - Global parameters file, which contains:
Include/use commands to bring in the above
All my project specific measurements
Tolerance/Fudge factors
variables I may change - Sub-assembly files
Intermediate calculated parameters
Modules for each component in the sub-assembly
2D rendering for any laser cut parts - Final assembly
Include files for the components above
Call the modules from the sub-assemblies, in colour where
appropriate.
Any comments or suggestions on this, and how I could fit in batch processing
where I need it?
Cheers,
Alex

To be frank, I am just making analogy with C language workflow:
i.e. output .stl file depends on the relevant .scad file AND all its
dependencies - I guess the dependencies list includes the global
parameters file, include files, imported .stl-s and the like.
If that .stl should be generated with the same makefile earlier - this
is Ok, make can handle it.
I am not aware about details of your current workflow to say something
more detailed :-(

Beware, make can act strange when fed with paths or file names
containing blanks, non-ASCII characters or reserved characters like
ampersands or braces. This problem seems to be worse when using make on
non unix systems, btw. In hugin (http://hugin.sourceforge.net/), make
has been used for generating panoramas from multiple input images, but
it had to be replaced with a processor of our own in order to overcome
these problems.
With kind regards
