Wish Two Module Wishes

LWGShane · Monday at 6:51 PM

I would love to see the two abilities be added to the B4X lineup:

Add multiple modules of the same type by using a separating character (ex: ";") in the "Add New Module" dialog.
Duplicate module... Suppose you have a module (a CRUD,BREAD, or other module) that you use as a template. Now I know you can create a new module and then select all and paste, but I would like a "native" way to duplicate modules. I would also suggesting making this feature (if implemented) compatible with wish #1.

Thanks for the consideration.

It would be very useful to be able to create custom classes (or code modules) just as you can with projects.

An alternative would be to save a module/class with "Save As," thus having a duplicate (which, however, must then be loaded into the project).

(?) "Save as template"

Yes, it could be useful in some cases, especially with B4XPages.

But what bothers me is having to go through N menu items (the mouse cursor sometimes moves to the wrong item and you have to go back to the starting point); "many" missing buttons like this would be useful.

1. Code Snippets is useful especially use with template tag.
2. Reusable projects can also zip as Project Templates.
3. The project template and b4xlib can contain reusable classes.

These features eliminate copy and paste code.

Direct, toolbar-accessible methods would be better in many ways, which I won't list here.

If it's complicated for Erel to add template class/module management, perhaps the following solution would be easier -PERHAPS - for him: implement drag-and-drop of files (classes/modules) from a folder to the IDE-project (the File tab currently accepts file drops).

You could then create a macro/comment to open your folder containing the template classes and...!

If you put the code snippets inside a b4xlib then it is available by start typing "code".

If the custom class is distributed inside project template, it is available when adding module from menu Project or right click in module tab.

For me this is very convenient already.

Example, I have added WebController and ApiController classes in my web project template in the past.

Just not many B4X developers make use of these features.

I really like that one, but I don't understand how it works!

If I use one of my project templates, will I have that menu item to add a class that is part of the project template to the current project?

P.S. Mario, just try!

Tried: no, unfortunately it is not like that. It seemed really unlikely to me.

Unzip the b4xlib to see.
You need to add the class with file extension .b4x_excluded

I'd forgotten about it, and most importantly, I think I've written several times that it would be useful to be able to create your own class templates, like for projects, but Erel never commented with something like:
"It's already possible"
(perhaps he didn't do it so as not to make me look bad!)

Perhaps, I repeat: perhaps, at the time I thought it was only for B4A (or maybe that was the case at the time, initially).

Thank you, @aeric

Maybe you are not.
Actually I think this is not a documented or an official feature.
The concept was first introduced in jar library. One day I was curious and made my own experiment and it did work with b4xlib too.
My bad I didn't share this idea but it is one of the "hidden" ideas in my WebAPI Controller b4xlib as a "bonus" for who "followed" and test my libraries.
It just not obvious.

Already available, drop them on the Modules tab.

Yeah, I don't even know what I wrote

It is so, in B4A it doesn't work

I see that my test.b4xlib doesn't "work" (for what we said) even in B4J.

(Added also a code module, just for test, but it was obvious that this could not be done, but in the Modules tab I do not even see clsMyClass, neither in B4A, nor in B4J).

Hmm...
I just tested. ~~B4xlib doesn't work in B4A but you can use .jar + .xml library.~~ B4Xlib Custom Class works in B4A, B4i and B4J !!!

B4XLib structure:

manifest.txt file:

B4X:

Author=Aeric Poon
Version=1.00
CustomClassTemplates=Aeric's B4XPage|B4XPage3,Aeric's Sample Class|SampleClass

So the trick is that:
CustomClassTemplates in the manifest file, I suppose.

Never read before!

Yes.
You can unzip B4XPages.b4xlib to see how it works!

But why did you post a .jar file?

(I have to wait (hope) that my damned headache goes away and then read better)
