Mr. Flibble was right, I realized the name was too misleading.
 
That realization came now half a year /after/ publishing an article
about it.
 
Anyway, it's <url: https://github.com/alf-p-steinbach/Wrapped-stdlib> now.

I never say I told you so but I told you so.
 
"stdwrap" would be a better name IMO. :)

The woman caught in adultery. The Law demanded she (and her male partner)
be stoned to death, but Jesus showed her Grace and Mercy:
 
https://www.biblegateway.com/passage/?search=John+8%3A1-11&version=KJV
 
4 They say unto him, Master, this woman was taken in adultery,
in the very act.
5 Now Moses in the law commanded us, that such should be stoned:
but what sayest thou?
7b ... he ... said unto them, He that is without sin among you, let
him first cast a stone at her.
9 And they which heard it, being convicted by their own conscience,
went out one by one, beginning at the eldest, even unto the last:
and Jesus was left alone, and the woman standing in the midst.
10 When Jesus had lifted up himself, and saw none but the woman,
he said unto her, Woman, where are those thine accusers?
hath no man condemned thee?
==> 11 She said, No man, Lord. And Jesus said unto her, Neither
==> do I condemn thee: go, and sin no more.
 
And many other forgiven sins, for Jesus had authority to forgive sin
on Earth:
 
https://www.biblegateway.com/passage/?search=Matthew+9%3A6&version=KJV
 
6 But that ye may know that the Son of man hath power on
earth to forgive sins, (then saith he to the sick of the
palsy,) Arise, take up thy bed, and go unto thine house.
 
We learn the pattern of Christ's one-time human blood sacrifice,
being sprinkled on the mercy seat in Heaven, by studying the pattern
God gave Israel for their sacrifices ... and then in the rest of the
New Testament you learn from those prescribed by God to write our Bible
the details of the application of Grace, and how it works mechanically,
and spiritually. The blood of bulls were temporary appeasements,
a precursor foreshadowing of what Christ would do once and for all time.
 
It's there before you, Daniel. Stop being hostile toward it, and
approach the teachings of God as a little child and you will find it.

I don't think that story makes your point. It ends with "go, and sin no more", or in other words, from now on, follow the law. Do you follow the old Judaic law, Rick?

We are to obey His commands, but it's no longer for religious reasons,
as by the Law, but for this reason (at 28:29):
 
https://www.youtube.com/watch?v=XrbqVkoJa_s&t=28m29s
 
He explains why God gave us the Law, why He cursed the ground for our
sake. He's given us rigors to focus on to keep our attention on Him,
for if we lived as Adam and Eve did in the Garden of Eden before sin,
with nothing to terminate our physical bodies, no labor, no strife
or struggle, we would sit in idleness inventing ways to do new evil,
as we do in our modern world of convenience, even as history demonstrates
that man needs no additional encouragement to sin.
 
> Do you follow the old Judaic law, Rick?
 
I follow the guidance of the Holy Spirit, which is in agreement
with love ... love for God, love for man, and applications of that
love in our lives ... ie, you will see such fruit in all born again
believers as a general pattern of life.

Every time you evade answering a direct question it speaks volumes about
the credibility of both yourself personally and what you write about.
 
So, answer the question. How many chances do you get?

You don't care to hear the true response, Leigh. You and Stephen
Fry have it all figured out.
 
Go with what you believe. Demand answers that only give responses
framed in your dictate. See how much truth you find there in that
house of your own making.

The answer Chris seeks is not an answer that can be given without
first correcting the underlying error in understanding which led to
the question being asked in the first place. We're back to:
 
"When you spread peanut butter on bread, Rick, what do
you do with the shells? Do you recycle them?"
 
In order to seek the truth, the baseline understanding must be corrected
so the questioner himself/herself will see the error of the question
and withdraw it, as the understanding lends the true question, and
the true answer, without the need to even ask.

libwy-0.53 is released:
https://sourceforge.net/projects/cscall/
 
For many in this forum, I'd say libwy features building from clib
calls, not using "std::" (except few). libwy is basically a
'wrapper' library, but don't be fooled by the word.
 
Firstly, because many subjects(inappropriate) had previously issued
about the One Religion in this forum. I'm going to start from this
point, because of the similarity.
There actually had been many religions developed in the world since
the written history. From where I live, many religious beliefs are
associated with, or derived from Budism. Honestly, I do not know
which is which. As to Christianity, a statistics I saw there could
be up to 5000 varieties in the world(or US alone, 20 years ago).
Now I just simply tell myself that nearly every church or temple have
their own "interpretation", quiet difference, but some of which differ
so much so as has to announce as a new branch... The problem might
have been so risen because the bible says Jehovah says He is the only
one true God... (and the strange thing I recall is that the old
testament says He protects jews from its enemy... suggesting every one
not jew might be what's protected against, but latter comes the new
(2nd)testament says God can turn stones into jews...?)
But History, Truth is so strange, beyond human/my/your comprehension,
there might even be no Truth/History at all.
On the other hand, as I know of, Buddha or Muhammad did not said so.
...As to me, God is merely The Mother Nature, we don't need say much.
Proof(just touches it): The timespan of human from ape is probably 200
thousand years, which is 1 of 20,000th of the earth history. If Nature
decides to change the earth or History, minor task. Religion or
civilization is very trivial in It.
 
So back to the subject. "std::" is your God. libwy is a naturally
humbly born library from history for programs migrating from C to
C++ (it has been a "C++ library" for many years). Though many
deficiency exist due to, mostly lack of man power and requirements.
For beginners, the common saying is that C++ is easier than C. But that
is what those simple codes want you to believe. As you read or know
more or need more, it (using standard library) quickly becomes a monster.
Have you ever read the wording "no one really understand C++"?
Because most underlying stuff of libwy are POSIX things. If you really
don't like what libwy presented, only half of your time can be wasted.
For experienced C++ programmer, appreciate your review and opinions.
You can see libwy as a way to accumulate experience for what a C++
library should be or should have from users.
 
Finally, I do not strongly persuade you to rely your project on it.
Small projects are OK. libwy is relatively small. It's easy to modify
for particular needs or mix with other "C++ library".

There are other considerations, a very important one being ease of
testing. The longer a function becomes:
 
- The harder it is to test
- You need many more test cases, the growth is a non-linear
function of the line length.
- You end up with testable functionality buried in the function.
- You end up with reusable functionality buried in the function.
 
These effects and others are why you seldom see long functions in test
driven code.

Very few (unless you are writing Java...) call trees have "thousands of
tiny functions". Like Richard, I much prefer seeing code like
 
void f()
{
getSomething();
 
processSomething()
 
sendSomething();
}
 
or
 
void f( Value n )
{
switch( n )
{
case A:
processA();
break;
 
case B:
processB();
break;
 
case C:
processC();
break;
}
}
 
Than seeing all of the guts in one place. If I want to get an overview
I can quickly do so and if I want to drill down, I can. The important
thing is I have a choice.
 
This style of code is much easier to write in C++ than it is in C, which
might be why someone coming from a C background isn't used to seeing it.

Localised error handling is an excellent use case for lambdas, just take

Bingo. C++'s ability to define abstractions at zero runtime cost are
why you can do this reasonably in C++, but not in C.

Hmmm. I'm not sure I agree with this. When testing a function, the
only thing I need to know are the pre-conditions and post-conditions.
Any properties of the implementation (function length, multiple
exit-points, modularity, use of sub-routines, dependence on external
libraries)
 
Indeed, if we write our tests first, how can the test suite possibly
depend on the function length?
 
Rather, everything you say applies to functions that only have a small
number of pre/post-conditions (i.e. *simple* functions, rather than
short [although we expect these to correlate pretty strongly, especially
if the language is sufficiently expressive (i.e. not C)]).
 
Of course, modularity makes it easier to test sub-components during
development...

I use lambdas also inside a function if there is repetition (even maybe
2-3 repetitions). I dont like to repeat things :)

const char* spaceshipSpriteImagePattern

"{0,paper}"
"{1,ink1}"
"{2,ink2}"
 
"000010000"
"000121000"

"001222100"
"001222100"
"011222110"
"010111010"
"010000010"
"010000010"
};

auto& spaceshipSprite = spritePlane->create_sprite(
