Quoting is done by C runtime. Unquoting is done by C runtime.
Of course, the *intent* of quoting is to invert unquoting. So a
correctly designed CRTL would quote in such a way that unquoting will
produce the initial array (and visa versa).
In principle, different CRTL could provide different (un)quoting
rules. However, I myself know only one bullet-proof way (= no
information loss, and allows "typical" usage of DOSISH systems):
0) Not-in-quotes whitespace is ignored, and separates arguments;
a) "\x25" (="\"") starts/stops quoting mode IFF it is preceeded by
even number of backslashes (including the case of 0 backspaces).
b) If "\"" is preceeded by 2n or 2n+1 backslashes, n backslashes are
included in the corresponding argument.

Sorry, I cannot read this as a statement given any thought...
a) "quoted" 1-arg system() is NOT equivalent to multi-arg system()
(but, given enough intelligence, it MIGHT be possible to give the
final result of running these to be the same -- however, I do not
remember anyone implementing this);
b) You assume that it is humanly possible for "an application
programmer" to do it correctly. I do not think this is a
practically meaningful assumption.

It is MUCH easier to write
$b = sin $a;
"correctly" than to
a) implement an emulator of a Turing machine in Perl;
b) write a Turing machine program which calculates sin(),
and do it "correctly". I would even say that the second task is
impossible without a major collection of test cases on which one would
be able to debug the code.
[ Writing a correct "quoter" for 1-arg system must be much easier;
on the other hand, getting a good test suite without having the
code for CMD.EXE may be much trickier... ]
Hope this helps,
Ilya

No it's not. It's done by win32.c:create_command_line. The code in there
is sufficiently convoluted, and contains a sufficient number of comments
about things not working entirely as documented, as to make me very
unsure of its correctness in every case. For a simple example, it
appears to me from the code that
system q/echo/, q/"foo"/;
does the same as
system q/echo/, q/foo/;
which is absolutely not the case under argc/argv systems. If someone
with access to a Win32 machine could verify this I'd be interested to
know. For another, the code makes no attempt to quote arguments with
special characters other than space in, so presumably
system q/echo/, q/>foo/;
will not do what I would expect. I also don't know what difference it
makes that 'echo' is a cmd builtin rather than an external command.

MakeMaker's MM->quote_literal is a decent attempt at a cross-platform
quoter, though it has some oddities to do with passing through make
variables.

It's obviously possible to get any given case right. Given the
difficulty of getting it right in general (due to the unnecessary and
undocumented arbitrary quoting rules used by cmd and the CRTL) it's
probably better to let perl handle it than try to quote things yourself.
My point was that even multi-arg system still isn't *safe* under Win32,
and still doesn't guarantee cmd.exe (and/or whatever you've got in
%PERL5SHELL%) won't be invoked.

Well, don't worry - nobody is going to ban you from Usenet (except
possibly the Chinese govt).
OTOH, nobody here much cares.
So, rant on - it's what Usenet is for. ☄

And that one (completely accurate) sentence is really the core of virtually
all of your troubles, isn't it?
Usually, as people mature, they learn by experience that their
communications are accepted more easily if they are presented with calm and
courtesy. This is neither good nor bad, nor is it a conspiracy. It is
simple human nature.
If you want your words to be heard, you cannot continue to ignore human
nature. You might not LIKE reining in your vitriol, and being pleasant to

whether anyone reads your words, then please feel free to continue with

IANAP, but I suspect that parts of his brain don't work the
same way most of ours do and he has a very limited ability to
perceive things from another person's point of view. This
results in an inability to communicate effectively and a
crippling lack of understanding of the social conventions that
most of us figured out and adapted to by the time we were 8
years old. He probably is honestly unable to understand why
other people react the way they do to his postings. If I were
going to have to pick a label, I'd say he's got Asperger's
syndrome or a similar autism spectrum disorder.
From the AS Wikipedia article:
Unlike those with autism, people with AS are not usually
withdrawn around others; they approach others, even if
awkwardly, for example by engaging in a one-sided,
long-winded speech about a favorite topic while
misunderstanding or not recognizing the listener's feelings
or reactions, such as need for privacy or haste to leave.[5]
This social awkwardness has been called "active but odd".[1]
This failure to react appropriately to social interaction may
appear as disregard for other people's feelings, and may come
across as insensitive.[5]
...
Although individuals with Asperger syndrome acquire language
skills without significant general delay and their speech
typically lacks significant abnormalities, language
acquisition and use is often atypical.[5] Abnormalities
include verbosity, abrupt transitions, literal
interpretations and miscomprehension of nuance, use of
metaphor meaningful only to the speaker, auditory perception
deficits, unusually pedantic, formal or idiosyncratic speech,
and oddities in loudness, pitch, intonation, prosody, and
rhythm.[1]
What particularly struck me was the "use of metaphor meaningful
only to the speaker" and "unusully pedantic" aspects of Xah
Lee's posts.
If somebody with AS can't recognize a listener's reactions when
they're face-to-face, you can imagine the difficulty they'd
have on Usenet.
There you go: a 30-second psychological diagnosis by an
electrical engineer based entirely on Usenet postings. It
doesn't get much more worthless than that...

Here's the thing - most people don't get banned from anything even once, let

As you know now, using fork() for startup of a child process was one
of the most brain-damaged decisions of designers of a certain one-user
non-multiprocessing OS for micro-computers.
When people say that "fork() is efficient" they mean just that it is
"more effecient than it was when one had no COW optimization".
Hope this helps,

P.S. I wonder why people do not enable Perl to use the POSIX variant

It does what you had said, BUT it's not the solver. The solver is a LP

What Is Your Favorite Lisp
Xah Lee, 2009-03-04
Javier wrote: =E2=80=9CWhat open source implementation of Lisp do you prefe=
r
and why?=E2=80=9D
My fav is Emacs Lisp.
Because it is practical. More or less the most widely used lisp today.
Considered as a tool, it has probably some 10 times more users than
either Common Lisp or Scheme Lisp.
For example, i consider emacs lisp, more powerful than Perl, as a text
processing language, for 2 major reasons: (1) It has buffer datatype
and associated datatypes such as point, marker, region, etc. Which is
more powerful than treating text as inert chars and lines, which Perl,
Python, Ruby, etc do. (2) elisp's integrated nature with emacs. This
means, for odd text manipulation jobs that happen daily in every
software coding, i can write text processing programs that interact
with me while i edit. (See also: Text Processing: Elisp vs Perl.)
The above paragraph, details why i love emacs lisp. However, it is not
so much caused by lisp language's nature. I find nothing in particular
of lisp lang's features of emacs lisp that made me love emacs lisp,
other than it being a functional language. It is not difficult to have
another language, or a new editor with a embedded lang that functions
similar to emacs. However, emacs just happens to be almost the only
one, or the most prominent one. (i am a expert in Microsoft Word in
early 1990s, and although i haven't ventured into its Visual Basic,
but i know it can do scripting. I'm sure, now after almost 20 years,
and with Microsoft's =E2=80=9C.NET=E2=80=9D, it possibly might compete with=
emacs with
its elisp, but i know nothing about it to comment further. (i'd very
much welcome any comment from someone who are a expert of scripting
Microsoft Word with Visual Basic; on how it compares to emacs, if at
all. (if you don't have say 1 year of full-time experience in this,
please spare me your drivel))) (also, numerous emacs-like editor with
embedded lang exist. See: Thoughts On Common And Scheme Lisp Based
Emacs.)
As to the reason i am not a fan of the 2 other major lisps: Common
Lisp and Scheme Lisp. These 2, are little used in the industry. Common
Lisp is a moribund dinosaur. Scheme Lisp is little used and is
confined to academia. There is nothing in these 2 langs that i
consider elegant or powerful today. I would, in a blink of a eye,
consider Mathematica, OCaml, Haskell, more elegant or powerful.
I would like to see Common Lisp and or Scheme Lisp die a miserable,
horrid, deaths, due to fanaticism as exhibited by Common Lisp and
Scheme Lisp regulars in newsgroups. I consider these 2 langs not only
impractical and inelegant, but their people are the hog of any
possible progress of lisp in general. (See also: Language, Purity,
Cult, and Deception.)
I do consider lisp, or the lisp way, a lang with lisp characteristics,
can be the most beautiful, elegant language. (in fact, i consider
Mathematica being one such example) However, given the social milieu
of the 3 major lisp communities: Common Lisp, Scheme Lisp, Emacs Lisp,
it might happen when pigs fly.
----
Of the existing lisps, especially new ones, i support NewLisp, and i
also support Clojure. Personally, i'm not likely to invest time in
them in the next 5 years, if ever. Second to these, i mildly support
Qi.
I am a avid fan of functional programing, and was a big fan of lisp
too. Lisp, even just 10 years ago, was still a great language, almost
the only one that are much better than all others, in both practical
industry use and also academic theoretical considerations. But due to
the rapid development of software technologies and vast number of lang
today that happened in the past decade, including a profusion of
quality functional langs, i see little point in lisp. (See also:
Proliferation of Computing Languages.)

Emacs is a simple Lisp dialect for Emacs scripting. It is behind

Scheme: Typically one can start with DrScheme and one of the

Note that Rainer is a Common Lisp fanatic. He's been posting regularly
in comp.lang.lisp since at least 1999, and it seems to me he does not
know any other functional lang other than common lisp, but always
trumpet Common Lisp in every aspect, and is often aggressive in his
online behavior that you can often see he fight with other lispers
too. I think he's retired in his 50s or older. Much regular posters in
comp.lang.lisp are old. (majority would be above 40 i think. (I'm 40
myself.))
If emacs lisp is behind the times in many ways, which is true, Common
Lisp is also behind the times in many ways.
If you really want to compare lisps in the context of computer langs,
lisps in my opinion is pretty much obsolete. I'd recommend JavaScript,
Ruby, Ocaml, Mathematica, over any lisp. I think that each of the lang
above are superior with respect to the tech aspect. Also, each of the
lang mentioned above has perhaps 10 times more programers than all
lisps combined. (In the case of javascript, it's few tens of thousand
times)
You can start with some basic tutorial here:

If you look around all educational resources (books,
implementations) are around Scheme and Common Lisp. Emacs Lisp is
mostly NOT used in schools or universities. The universities and
schools that teach introductions to programming or computer science
using some Lisp dialect are using mostly Scheme (some are using Logo).
Universities are sometimes offering Common Lisp courses.
I fully agree with what you wrote above.
However, to put things in proper context, if the question we are
asking is which lang to choose among lisp for a imperative programer,
i think emacs lisp can easily be the right choice, for one simple
reason: pracitcal utility.
You see, to a professional programer, who is studying lisp to learn
some new language concept and aspects, elisp is of the most ulility
because:
* A: it has immediate practical utility. Most lispers use emacs
and swear by emacs for its multitude of uses and extensibility, even
if they program only in Common Lisp or Scheme Lisp.
* B: emacs lisp, although technically is useful just within emacs
and text processing, however, contain almost all the essential
features and qualities of lisp that are not in imperative langs.
Namely, nested paren syntax, symbols, lisp macros, functional
programing.
Put in other words: if a industrial programer coming from C, Java,
Perl, etc imperative or static langs want to learn lisp's concepts, he
can learn basically all of it with the very simple and useful emacs
lisp. If he is so hooked, he can then trivially extend his knowledge
and start to learn one of Scheme lisp or Common lisp and start to
write whatever real software he had in mind in these langs.
This is why, i recommend emacs lisp, among the 3 major lisps, for
imperative programers who want to venture into lisp.
(for those unaware, there are also NewLisp, Clojure, Arc. Their number
of users, and age of the lang, are roughly in that order given too.)
Now, if a imperative coder is wondering which lang he should learn
outside of his meager C, C++, Java, Perl, type of imperative langs,
for the purpose of enriching his knowledge in comp langs in some
academic sense, then, i do not even recommend lisp in particular. I
would easily recommend: OCaml, Mathematica, over any lisp.
All of us are busy, and all of us geeks always have aspiration to
learn new langs, but not always follow thru. If a imperative programer
tried to learn lisp for half a year in his spare time, then, whatever
he has learned with emacs lisp remains quite useful in his programing
career. If he kept on using emacs, his lisp knowledge will simply
grow. But whatever he learned in Common or Scheme lisp would rather
find no where to go and be forgotten.
