This answer makes no sense, and it explains nothing.

If you introduce arbitrary terms (here the attribute "strong"),
and have not even enclosed the whole term in quotes (as I did)
to indicate that you want to express some specific own concept,
you should at least explain (here in your post) what you mean.

Also, instead of issuing yet another new posts in a new threads
please followup in your original thread to my post for a reply
to my question so that I can see if and when you answered. That
makes it also easier to ignore threads completely. That's what
threads in Usenet are for.

I suspect "strong value" might be a superfluous synonym for "object".

I wouldn't have associated that term with "object orientation" or
some such. - I assume you have read his github docs?

[ snip elaborations ]

Is there a point in adding that to Awk? (Just interested in your
opinion.) Personally if I want OO in scripting I'd rather choose
any [scripting] language that supports it inherently (by design).

I.e. something that keeps its identity and state as you pass
it around anywhere you like. It's strong because its pieces stay
together, accessible through the same handle.

In Awk, you can't pass aggregate values around other than strings.

You can pass associative arrays down into functions, but not
return them, or assign them from one variable to another.

If arrays could be returned and assigned, they could be used to simulate objects with fields, like the way dicts are used in JS. (Which is not
great, but better than hacks like indices into global arrays to simulate pointers.)

Well, instead of
arr = a_func(args)
you can modify a_func to have
a_func(args, arr)

I understand how to get array data out of a function.

This breaks the abstraction and is also monstrously inefficient.

Imagine that objects are modeled with associative arrays. Now you have
to copy every time you want to simulate returning an object
from a function.

If the objects are treated as having mutable properties, the semantics
is wrong. You can't return an object by copy if you need the caller
to be able to mutate the original.

HTH.

No, it doesn't, sorry.

Hello Everybody

For those who write long programs in AWK, pointers and working with
strong values are essential.

What do you mean by "strong values"?

I would like to introduce to my small project - a compact user-level
awk library designed for generating "unique" strings that is may be
used as the abstract pointers in awk.

Do you (maybe) mean "references"? Or really "pointers" as we know them
from C or C++?

The library contains (I hope) good documentation

In my opinion, this library is key for the further development of
programming in awk as a whole. It provides users with pointers.

In the documentation, I tried not only to describe the programming
interface but also to briefly demonstrate the main techniques for
using pointers in awk.

Link to the project: https://github.com/digics/UID10

I would really appreciate hearing any feedback, comments, and
evaluations of my work. This applies to both the code itself and the documentation.

A quick general comment...

Awk is a HLL, abstracting from low-level constructs. It's beyond me
why you think that pointers would be necessary or even "key for the
further development of programming in awk as a whole".

I might say more if I'll have read the documentation.

BTW; I would have appreciated it if you'd have provided some minimum
more concrete information here in this newsgroup about the features,
rationale, and similar useful information, before directing us to
external Web-links to github trees.

Janis
