Just include code directly in the text (enclosing it by [ code ]..[ /code ]) tags, then it will look like this: % This code is maintained automatically, do not update it manually. % 17:51:34-16.8.2019 facts ok_ctl : button. cancel_ctl : button. id_ctl : editControl. predicates generatedInitialize : ...

Welcome back :wink:. In future please only have one problem in each mail. Mail threads becomes very complex when they are about several topics . The first problem sounds very strange. Please post this problem in a new mail, and include there relevant code in that mail. I will consider that problem c...

When going from one language to another, you may of course consider how things you faced in the old language is treated in the new one. But often you will find that the "things" in the new language is not the same as those in the old language. You should notice that Visual Prolog is a fully compiled...

It seems that something has only been implemented as a special case. But I do not recall the history around about this. Anyways, in principle the error is the correct behavior in all cases, because the predicates you call do actually not return values, and can therefore not be the second arguments o...

My colleagues agree it is the native expansion that is used. I have added the word to the documentation.

My brain has looked into some forgotten memory slots (or invented a story). Though this is not what consistent with the documentation, I think this is deliberate. What happens is that a an "expand" presentation, will show/write the first argument, but expand like the native expansion of the second a...

Yes, that it is a good question . We will look at it.

That is a bug, we will look at it. Thank you.

(Currently, you will have to put the presenter interfaces first in the supports).

I am sorry I was confused when I answered before. An "expand" presentation will be presented as its first argument, and expand as the second term. But an unsigned doesn't expand, so this presentation will not expand. In your case you should use a fixed presentation with a string and a "child only" c...

No, that is a bug.

By the way, (it will not solve the bug, but) you can write your presenter like this:

Not to my knowledge.

No.

It is correct that we had support for some Unix variants back in vip5. But we didn't use the Unix version ourselves and subsequently it was out of focus and thus under-considered, under-developed, under-tested, under-bug fixed, ... All in all it was just waste of resources on a product of low qualit...

Thank you, for your advice :-). You can already write web services in Visual Prolog (micro or something else as you like). The .net platform does not require you to use a specific programming language. But ... the .net platform has a built-in mandatory type system, which any programming language on ...

No.

Nor can it compile for Linux or macOS, but some have successfully run Visual Prolog programs on Wine.
