Function Application is not Currying
Xah Lee, 2009-01-28
In Jon Harrop's book Ocaml for Scientist at
http://www.ffconsultancy.com/products/ocaml_for_scientists/chapter1.html
It says:
Currying
A curried function is a function which returns a function as its
result.
LOL. That is incorrect.
Here are some examples of a function that returns a function as
result, but is not currying.
Mathematica example:
f[n_]:=3DFunction[n^#];
f[7][2]
(* returns 49 *)
Emacs lisp example:
(defmacro f (n) (list 'lambda (list 'x) (list 'expt n 'x) ) )
(funcall (f 7) 2)
Perl example:
sub f {$n=3D$_[0]; sub { $n ** $_[0]} };
print &{ f(7) } (2);
Javascript example:
function f(n) {return function (x) {return Math.pow(x,n);}; }
alert (f(7) (2));
In the above, a function returns a function, and the result function
is applied to a value. They demonstrate 2 things:
* The ability of the lang to have a function that returns a
function.
* The ability to apply a value (of type function) to a value.
These, are 2 of the features that is part of often sloppily termed as
=E2=80=9Cfunction as first class citizens=E2=80=9D.
However, the above are not languages that support currying, which is a
feature that Haskell & Ocaml has.
So what is Currying?
Wikipedia article Currying said it best:
In computer science, currying, invented by Moses Sch=C3=B6nfinkel and
Gottlob Frege, and independently by Haskell Curry,[1] is the technique
of transforming a function that takes multiple arguments (or more
accurately an n-tuple as argument) in such a way that it can be called
as a chain of functions each with a single argument.
Note how it says =E2=80=9Cis the technique of ...=E2=80=9D.
To be more concrete, in the context of a given computer language, to
say that it support curring, is to mean that the compiler understand
the concept to certain degree. More to the point, the language is
inherently able to take a function of more than one arg and
deconstruct it to several functions of single arg.
To say that function returning function is Currying, is a confusion of
fundamental concepts.
Mathematically, currying is the concept of deconstructing a function
of multiple parameters to a composition of several functions all of
arity 1.
I like Jon, because i consider majority of his argument and
perspective are more correct or sensible in his trollish spats in
newsgroup fighting with tech geekers. But he is really a asshole, and
take every chance to peddle his book. Every mother fucking
opponitunity, he injects random opinion into discussions about how
static typing or greatness of Microsoft, which paves a way for him to
post a link to his book on Ocaml/F# or =E2=80=9Cstudy=E2=80=9D or =E2=80=9C=
speed comparison=E2=80=9D
of his site. He does this repeatedly and intentionally, about every
week for the past 2 or so years, and write in a way to provoke irate
responses. In the past 2 or 3 years, i have for 2 or so times without
his or anyone's solicitation, publically supported him in ugly
newsgroup fights (such as some serious sounding post that accuse him
of spamming or or some real life threats about network abuse).
However, in the past year as i have had some debates on language
issues with jon, i find Jon to be a complete asshole as far as his
newsgroup demeanor goes.

where Jon started a fight with me )

The PHP newsgroup is where you want to ask, or did you have some part of
your script that uses Perl? If so, does that part work and you
actually need to ask about pdftotext? Either way, I think you've
mistakenly posted to the wrong group.

[snip]
Since this may be searchable, I'm going to add a critique on your apparent final form.
I count 7 substitution regexs' above and one split. This occurs per line of data read in.
Things that were thrown out:
1. Positional field validation, number of fields validation, form of field validation, field parametric validation ...
(the list is endless here)
2. Empty line/things that break code... again endless
3. Redundancy, repative pos(0) searching loops pre-validation, performance issues
4. Even the slightest fallback error reporting for anomolies, no recovery
5. The notion of confidence in the parsed data
6. Refactoring ... the most important step
This is a sample output line from a print "@record" after all the regex substitutions:
"Sun 20 41 55 -18 15.1 0.985 31.290 28.986 Up"
They all seem to be the same. How did you determine this is what is needed?
The regex substitutions and split(), along with NOT validating anything,
suggest that you are firmly positive and confident of the form of not only the input
line, but the result after all these substitutions and split(), that you will get
the desired field data described above.
On this premise, and asuming that the only question is whether it will be just "Planets"
as the first field and some "text (Set/Up)" in the last field, there are only numbers
inbetween. Float and decimal numbers aren't distinctive in Perl, so you have a pattern
that is ALPHA CHARACTERS in the beginning, NUMBERS in the middle, ALPHA CHARACTERS at
the end.
I thought you were on track to validate fields/data et al, when you originally had that
huge ass regex, but you settled on the above as a final form, which does absolutely nothing
but try to stress test the regex engine to prove that you can remove one character at a time
from a string, the character you think (not know) is there, in an actual string, and by
searching from the beginning every time. On top of that, using split() as the grand finale.
If you take all of your regular expressions from above and replace it with this single regex:
my @rec = /(^\s*[a-z]+|[\d.+-]+|[a-z]+\s*$)/ig;
It produces the exact data output (and leaves the '+'):
"Sun 20 41 55 -18 15.1 0.985 31.290 28.986 Up"
In 1/50th the time that it takes to do all of your combined single character, re-start
regexs' and split(). And it does what you want to do, no validation.
As far as the '+' sign in text form? Thats all it is. Each number scalar has an internal
"text" representation (if its used textually) and "numeric" representation (if its used numerically).
$number = "+27"; print ($number * 1),"\n";
In the end, this was a learning exersice, nothing more. There are significantly harder regex
parsing circumstances. Some parsing conditions that would make your mind bend into a pretzl,
where the mistress of darkness has got you in a Kama Sutra position never thought possible.
But, the book is closed on this caper. Only took 300+ posts to figure it out ...

Yes.
This can be inferred by the name of the feature.

A: The buffer is being flushed.

Note that this code does not do the same thing as the code quoted above.
The code quoted above normalizes true values to 1 and false values to 0.
This code only normalizes false values to '0', leaving true values
in their original form.

#!/usr/bin/perl
use warnings;

Yes. Contrary to what some people apparently believe, it really isn't

No. Consider:

my $bool = (1 < 0);

Semantically that would be quite simple. The question "can this process
with its current priviles read/write/execute this file?" can always be
answered given the file's ACL and the process's privileges. But it may
be impossible to implement:
1) access(2) doesn't do what one might think it does.
2) So it has to be done "manually": Get the ACL, get the current
privileges, compute the result - this means duplicating OS in an
application, and you will almost certainly get get some detail wrong.
3) You may not even have access to the "real" ACL: A filesystem exported
over some network filesystem protocol may have no way to convey the
exact ACL - but it will probably still enforce it's rules.
In conclusion the only way to be sure whether you can read, write or
execute a file is to try it. Reading and writing (non-destructively) is
trivial for regular files, but executing isn't (you may not want to
execute "/usr/local/bin/delete_all_my_data" just to find out whether it
is executable), for directories read and execute are simple, but write
is impossible (you would have to create a file in it).

I am a little more than worried that you keep saying all the time, in
fact, continiuously, "can't" and "regex" when it comes to parsing markup.
Markup and 'C' are somehow magically compatible when it comes to parsing,
but Regular Expressions aren't somehow ???
XHTML/XML/SGML and HTML standards are now and have been for quite some time
defined with REGULAR ESPRESSIONS exclusively. Maybe you should consult a
doctor about your dimentia !

The quote is below. Its a great example of no such thing. A variant

There is NO VARIANT of Linked Lists.
There is NO SUCH ANIMAL, period, excalamation point !!!
Every List has a head and a tail, a List cannot exist without them !!

You weren't alive in 1980 to begin with, the PC came off the presses around
November 1981 from IBM in Boca Raton, Fla, Amiga Kernel compiler was written
in Bcpl around 1984-85, and the first notion of "Node" was that that you found on
your genitals, whenever that was.

"Circularly-linked list" is the title. Aka, "Double-Linked Lists".
The circular thing is the "Ring-Worm" trolling through your brain.

Odd, perhaps it was just needing something to restart (a service, or
whatever). Were you running this through a web server (Apache, IIS, or
whatever), or from the command line? If a web service via CGI, that
might make sense if it basically cycled the service after it started
again. It's been many years since I've used Windows (Thank God), so I
really don't want to guess further about why it would have suddenly
started working without changes.
