D - enum

they really are an enum and I'd lose typechecking capability. I suppose I

Sure. I'm not advocating that we end up with Java's ridiculously low
functionality : SLOCs ratio, but there are certain issues that seem pretty
cut and dried (I'm just putting up my umbrella in anticipation of you all
raining down scorn upon me) such as:

1. Mandatory braces. Almost all experienced programmers end up putting them
in everywhere, so let's just admit that the odd bit of typing now will save
masses of effort later. IDE macros can easily be made to do this for us
anyway, for those who dislike key-presses.
2. Conditional expressions must be boolean. Thus one must compare integrals
against constant

    int    i;

    ...

    if(i != 0)

and pointers (sorry, I mean references, spot the C++ programmer!) must
compare to null

    SomeObject    o

    ...

    if(o != null)

This is not going to affect generated code in anyway, but is (i) more
immediately accessible to the reviewer/maintainer (not to mention the
original author some months later), and (ii) less error-prone

I believe there is a precedent for this kind of rigour (unless memory
misserves) in Walter's requiring all enum members to be mentioned in switch
statements (of enums) as a guard against addition to the enum without
addition to the switch case list. (Can someone refresh my memory as to the
exact nature of this post?)

Reminds me of my own torrid programming past.  As a deeply-embedded C
programmer for 20 years now, one who was brought up on assembler, I still have
this craven need to write monstrously complex functions in two or three lines
of impenetrable obfuscated C.  The goal is to do the most with the fewest
keystrokes, yet make the fastest possible code.

My peers hated it.  My bosses hated it.  When I became independent, my clients
hated it.  But you see, sometimes I just had to do it.  I couldn't resist.  I
want to push C down to the level of finely honed assembly macros (which can get
positively Forth-like if left to their own devices).  And if the rest of the
world couldn't understand it, well, it just proved they didn't really know C
all that well.  Right?

To make everyone shut up, I started putting the "correct" code in there as
well, then I'd use the preprocessor to switch between the two instances.  I
could show the two were functionally equivalent (and on some occasions they
even produced the same code).

Well, compilers got smarter, the style battles got harder to fight, and
programmers got dumber (in a good way ;^).  Simple straightforward code is what
everyone wanted, and I finally caved.  Now I use braces and semicolons and
parentheses everywhere they can legally go.  I no longer pay attention to
operator precedence:  Parens make that a non-issue in all but a very few
cases.  I no longer ever have "if" and "else" on the same line, and always have
full brace sets between them.

I no longer define structs and enums in-place, even when they are throw-aways.
I use layer upon layer of typedefs to avoid the magic of tangled Gordian C type
declarations.  My include files are huge and comprehensive.  I use variable
names with more than one letter, sometimes they may even be found in
dictionaries (of some language).  Then I started using variable naming
conventions, so all my pointers start with p, and member data with m, and so on
to the land of the noted Hungarian.

Well, I did stop at that last one.  Nipped it in the bud.  I'm not that far
gone.  Not quite yet.

But then it got worse:  I started using "style guides" and "coding standards".
Then I even started writing the damned things!  Then my code started to go
through the pretty-printer/reformatter without even a single change.  (BTW,
"astyle" rocks.)  I even started thinking the blasted tools "rocked".  I
started using lint and "-Wall", and my compiles became warning-free.  Pffft.
Warnings are feared only by those who don't know what they mean.

I had to enter so many more characters in my code that I actually had to stop
looking at the keyboard while I typed.  My comment-to-code ratio went from 1:10
to 2:1, and I even started using documentation generators (which would always
gag on my old code).  I had to go to ever-higher display resolutions on
ever-larger displays to get enough code visible in a single window to hold a
complete thought.

My functions had only a single entry and exit and were goto-free, with each
loop fully closed, each if else'd.

Yes, I truly caved.

But I still sneak in the occasional line or two of raw distilled power-code.  I
am a man, dammit!  And I can still code my way out of a paper bag.  But I do it
with about 20 lines of surrounding comments. (It feels like wrapping a diamond
in burlap.)

My "safe" coding has had its cost:  I no longer solve those PC-Lint puzzles in
a single glance.  Sometimes it takes two glances, taking a pause between them
to adjust the reading glasses on my nose.  I no longer "see" code in the empty
editor window, like I did way back when, when the hardest problem was making my
eyes keep up with my fingers on the keyboard.  Now I actually have to do
designs.  And do eye exercises.

But at least my typing has improved.  It allows me to write long, wandering
posts to newsgroups in the blink of an eye.

I like D simply because it removes so much of the temptation to delve into
obfuscation.  The only problem is that I have to fire up a Windows system to
use it.

Did I mention I'm really good on the keyboard?  I hate mice.  I hate windowing
systems that don't have keystrokes for doing everything.  I hate MS Windows.  I
hate that D runs only under Windows.  I hate that I have to take down my
ultra-stable SMP Linux system, and reboot into Win98 (and give up a processor)
to run D.

But it is worth it, once in a while, if only so I can avoid the seductive siren
call of minimalist C.

Somebody shoot me.

If you were an attractive lady, and I not unattached to mine, I think I'd

Almost completely agree with everything you say, particularly salient is
your description of the maturation process from hero-geek to software
engineer. I'm always bemused when people have not made that transition after
many years in the game. Surely it's either that they've been working on the
same product/project, for the same company, using the same technology. Like
you, once reviewing and teaching became a large part of what I do, the use
of all those neat tricks (that still appeal, as you say) becomes untenable.
How can one say "you must do x" when one is still doing "!x". Down with
hypocrisy, down with short-term solutions (minimal coding now for maximum
maintenance in the future). One of the _few_ good things about Java is that
the compiler enforces a few good things (missing / superfluous exception
catches, boolean conditional statements, etc.) on the practise of its
programmers.

On thge subject of Hungarianism, always making conditional expressions
boolean aids with reducing the amount of Hungarian. In addition, by forcing
pointers/references to compare to null (rather than 0) also assists. Pretty
much only use p and cch/cb (differentiation between count of characters and
count of bytes is very important in Ansi/Unicode C/C++) these days.

Matthew

P.S. Agree D rocks, but there's a lot more stuff needed until it blasts the
hell out of Java and C# (I know Walter doesn't see it as a competitor for
these languages, rather as an evolution of C++, but that's exactly what I
see as its most important (from a political point of view) target).

 When this group was first set up, I thought it would need moderation







 at com.lang.* newsgroups for comparison). I've been delightfully pleased
 that it needs none at all.



 But I do think an important part of this is that you
 are on your own server? I have not yet seen a single
 spamvertisement here, a great relief!

 Also, on this group there aren't so many people that
 flame you to death if you post off topic, if you
 didn't read the f*cking manual or if you simply
 disagree with them. I love it here and it is one of
 the only groups I ever go recently. Posting on or
 even reading comp.lang.c++ just doesn't seem worth
 it any more... :(



 It's like my experience in the compiler business. I've never needed to




 with the problems that other mail order businesses seem to regularly
 experience. My conclusion is that the products I make simply attract a




 higher quality of customer than the competitors do <g>.



 LOL! :)
 We can all safely agree with that!

 You won't need to qualify them if you make them anonymous enums, like:

Just make an alias:

    enum { ... }

This worked fine for me. =)

But that may be just because I come from a C++ background where enums do
work like this.

In fact to be perfectly compatible with C++ enum, it'd have to be completely
rewritten:

instead of :

// in C++

enum Colors { red, green, blue };

// in D

typedef uint Colors;
public const Colors red = Colors(0);
public const Colors green = Colors(1);
public const Colors blue = Colors(2);

Now that sucks.

It defines the underlying type of the enum, rather than letting the
compiler select it.
