Hash mark prefix to a string
I asked this question on the Pike channel on libera.chat but nobody is lurking at the moment. :) what does the # mean herein the following? [code] str = #"This is a multiline string terminated by a double-quote like any other string"; [/code] I've searched all the available docs that I can find, but have yet to stumbled on an explanation of this syntax.

OOP syntax help
I've /never/ been fond of OOP, but if I'm to continue with Pike, I figure I should at least try to understand Pike's very of OOP. From: https://pike.lysator.liu.se/docs/tut/oop/creation_and_usage.md [quote] Creating and Using Objects Assuming that we have the class animal, we can define some variables that can be used to store animals. Remember that the class is also a data type. We can also create some animals to put in those variables. To create an animal, we use the syntax *classname*(), i e the name of the class followed by a pair of parentheses. animal some_animal; some_animal = animal(); animal my_dog = animal(); [/quote] The three statements are confusing to me. So a class called "animal" has been created and exists! OK .. "animal some_animal;" ?? Are we cloning the class here to create an object? "some_animal = animal(); ?? So what's this than? "animal my_dog = animal(); ?? It seems to me that this should be the cloning statement to create a particular object of the animal class? It's all a bloody muddle to me. I'm sure that I must be reading it wrongly. -- Duke ** Text only please. Bottom post is best for me **

And it could be expanded for more advanced features! It _would_ be a great advocacy opportunity as well. Because it could be a community effort, there would be no need to wait for yet another book(s), or blog(s) to be written as time permitted. The initial time and effort would certainly be non-trivial, but IMO it's absolutely necessary to spread the use and usefulness of Pike. Unless the few core developers would rather the language remain a close-door, private project. In which case the public should not be exposed to the language at all. It would not do your book project much good though. IMHO, Pike and its quality capabilities are freely available and so should quality documentation and tutorials for it. The https://learnxinyminutes.com site seems to be the quickest way to get there. A link to it on Pike's homepage would be all that is required and newcomers to Pike would be spared the hunt-n-peck search for a complete up-to-date set of docs. Anyway, this Pike noob won't probably ever see that happen. I first looked at Pike 10 or so years ago, and like I said previously nothing about the documentation has changed much during that period. There must be a reason for that! Of course, maybe you guys want it that way - a closed shop! Good luck! -- Duke

Have you guys ever considered using the following: https://learnxinyminutes.com Lot's of examples there! Githup-based! Could easily become a community effort. Standardised presentation!! There could be followups like "Learn More X in Y minutes" Where X=pike for more advanced stuff. Just a thought! Using that site would also give Pike extra exposure. -- Duke

I found out for myself that pragmas don't work in Hilfe - but
thanks for confirming it and for the alternate option. I'll give it
a try.
I work with emacs most of the time, so I'm trying to figure out a
slick workflow to learn with. Doing the learning code in Hilfe is
great, but if it's limited than it might cause more confusion which
I don't need.
Thanks agian ..

Do you mean that the #pragma can be used in Hilfe as well as

I don't use IRC, other than for my Twitch bot. Awesome! So it seems to me that Pike should be able to give Ruby, PHP, Perl, Python etc a good run for their money in the Web backends domain.
