Yes, and warnings are not failures.  Exponential-notation-like words
have never been usable as identifiers.  Hex-constant-like words are no
longer usable.  As I said, we now warn that all such names are on thin
ice.  For instance, it is not implausible that 0oXXXXX and 0bXXXXX might
be used for octal and binary constants.

I also consider it strange and confusing that 1e12 is a number, but
1e12x is an identifier, or that 0xDEUCE is a valid identifier but 0xACE
is not.  Or, for that matter, that 1xACE is a valid identifier but 0xACE
is not.

I suppose I should ask "what file" line 15.

Usually that means an unnamed unsaved file - the file in front of you
in the editor.

Ah, ok, classic use of "." in a path, gotcha

I get a subtly different message:

WARNING: Can't find include file 'nonexist'. in file ., line 1

The first dot, after the close quote, is I think just a bug.  The
particular call thinks it's writing a full sentence, so ends with a
period, but then the logging infrastructure goes and adds the "in file"
part.

The second dot I suspect is the result of canonicalizing the empty
string - which, because of long (and arguably bad) UNIX tradition is a
synonym for ".". But really the infrastructure should be smarter than
that, and recognize the empty-name case and say something like "in the
current file" or "in an unsaved file".

I also consider it strange and confusing that 1e12 is a number, but
1e12x is an identifier, or that 0xDEUCE is a valid identifier but 0xACE
is not.  Or, for that matter, that 1xACE is a valid identifier but 0xACE
is not.

I've always been sad you can't use scientific notation in base 16 in, uh, every computer language?

(For those confused: e is not a number is base 10, so 1e12 is unambiguously 110^12, but it is a number in base 16, so 0x1e12 could be 116^18 (in decimal) OR 7698 and so nobody bothers with a special syntax when you can just write 0x1*0x10^0x12 if you intended that)

Not really relevant to this specific discussion but certainly appropriate to the title...
Am I the only one who thinks it's WAY past time to retire 2021.01 as the default download?

I have no doubt that particular question came up multiple times long before I got here, but having something of that vintage as (presumably) the "newest" stable version kind of screams "abandoned project", which I know is definitely not the case.

I'm looking for the latest, but most stable, version of OpenSCAD.  Going through the snapshots, it looks as if 2026.01.19 is it.

Do I have it right?  The website says that the latest stable version 2021.01, which I have.

No!   Should have been retired by late 2022. Much has been improved since.

Chris,

Identifiers that start with digits should definitely be phased out. Only
ancient languages like COBOL, LISP, FORTH and TCL allowed it. LISP has
the same problem as OpenSCAD. It just gets to be too ambiguous:

(setq 6e 1.5)

1.5

(setq 6e2 1.5)

*** - SETQ: 600.0 is not a symbol

Maybe as an interim compromise, only one warning could be printed,
when the first identifier is encountered beginning with a digit, so it
wouldn't be prohibitively annoying.

As a path forward for NopSCADlib, how about using an update script? I'm
attaching a Python script that updates all the subject NopSCADlib
identifiers in all .scad files within a directory, recursively. It could
also be included with the library to allow library users to update their
code with one command. Then you'd be right back onto the latest releases.

 Yes, and warnings are not failures. Exponential-notation-like

Chris, Identifiers that start with digits should definitely be phased out. Only ancient languages like COBOL, LISP, FORTH and TCL allowed it. LISP has the same problem as OpenSCAD.

One warning is too much because I run with stop on warnings. I am
terminally ill, so I have better things to do than rename all my
vitamins to more ugly names and update all my projects.

Identifiers that start with digits should definitely be phased out. Only

(setq 6e2 1.5)

*** - SETQ: 600.0 is not a symbol

Maybe as an interim compromise, only one warning could be printed, when
