Nice!

Also, I'd like to have $date and $now.
OpenSCAD version is based on date, which I like very much. I've not seen any
other program do so. Very often I find a program on the net, it says version
2.3.1 or something, but who knows it could be as old as 20 years back.
Using date/time immediately gives a sense of how recent the program is. I'd
prefer it that way. Before I start using git, I labeled my "versions" by
dates like 20150503-1. Year always up front so they can be sorted.
Another usage of $date and $now: logging --- if you want to output echo
to a file for logging purpose.

hi,
any way we can get the filename(s) being built stuffed into a special
variable?
like, say, $fileName? or $fileNameArray?

We already have the stack of modules available as variables:
A nice example of this feature is described here :
https://github.com/openscad/openscad/pull/460#issuecomment-23049813
It would have been nice if parent_module() returns a vector of [modulename,
filename], that way we would have better information about the context.
[modulename, filename, path, timestamp] would be even better. It would also
clarify the issue : does file_name() return the file location of declaration
or of use. With that feature :
name = parent_module(0);
echo(name[1]);
would give you the current module definition
name = parent_module($parent_modules);
echo(name[1]);
would give you the current file.
As for a "number of times F6 was pressed" counter, there is no place to
store that. It should not go in the file (only i edit the file) and it is
impossible for openscad to decide if this is actually a new version. Version
control systems can output version files which you can include in the
source.
With all this meta information available, it would be nice to get rid of the
"echo" in echo() and be able to format stuff prettier. I'd like to be able
to generate openscad files in openscad.

I have used several version control systems.
OpenSCAD is no different than any other programming environment where
the user's code is stored in text files. OpenSCAD files are already
accommodated in any system like git, bazaar, subversion, hg, you name it
(perforce, etc. etc.). Personally I use Bazaar, but anything goes.
I don't think it is the responsibility of OpenSCAD to do anything in
this area.

My OpenSCAD_DocTest lib https://github.com/runsun/openscad_doctest can
write formatted code to the console. It's, in fact, making use of OpenSCAD's
own features. So OpenSCAD can do some type of formatting.
Recently I recoded my lib to be able to generate html page. See here
http://doctestscad.runsun.info/doctest_tool_api.htm for example. The
webpage is dynamic and entirely generated by OpenSCAD, including HTML, CSS
and Javascript. The only post-process I need is to get rid of the unwanted
"ECHO: ". (see my python code
http://forum.openscad.org/Sharing-Dump-echo-output-to-a-file-td12529.html
for this purpose).
So it seems that OpenSCAD is already capable of doing what you want.
BTW, can you give an example usage of generating openscad files in openscad
?

I'm ok with echo() behaving as it does for quick debug stuff.
I'd rather have an explicit, C++ style 'printf()' supported. Devil's in the
details, but shouldn't be too difficult to implement using the echo() code
(most likely src file: src/control.cc) as a starting point.

I believe the requests about echo() are simply to have an option to turn off
the printing of "ECHO: ", which has no effect at all to those who don't need
it to be turned off.
The difference between that and the "printf()" is that, printf() can be
achieved by user function easily ( I can write one if needed), so having
openscad to include something like printf() is not that critical.
But the print out of "ECHO: " is something you can't overcome with user
function in openscad.

OpenSCAD version is based on date,
I'm not sure what you were after, but there is version().

The current date and time when file is executed.

I agree with you, but I think I did not make my point clear. OpenSCAD
doesn't need to build in it's own version control system. What I liked was
the idea of providing a scad file /access/ to the version info so that it
could be expressed within the 3d model.
