Just to show I'm paying attention, I have to say I've always been impressed with Klaus' documentation.
There are two points I should highlight:
1. It would be good if many examples were brought up to date or an example of how it would be written in B4X/pages. This, of course, is a rediculous expectation. It is just a dream.?

2. The docs would work a lot better if I remembered to refer to them. This would save me a lot of time. ?

Did you have a look at the B4XPages Cross-platform projects booklet.
It describes in detail, in the chapter B4XPages version of the SecondProgram project, the conversion of the SecondProgram project from the Getting started booklet into a B4XPages project.

Yep. I should have mentioned that.
I'm just being unrealistically greedy and didn't mean to be taken to seriously.
Just keep up the great work. ?

[johnmie]

OK, but what kind of information would you like to be added there ?

Generic terms & concepts (file handling, saving files etc.) and cross references - even better a list for beginners like me eg. saving a file see file.write etc.

 

[johnmie]

I noticed, so it all seems a bit pointless without the app being available.

https://bizgraphic.ch/installers/digi-libris%20installer.exe

https://bizgraphic.ch/installers/digi-libris-reader.app

 

[agraham]

The exe link is for Windows
The app link gives a 403 error but a .app extension looks like it might not be for Android.

 

[johnmie]

Sorry, my mistake. The app is indeed for Mac, use
https://bizgraphic.ch/installers/digi-libris-mobile.apk
(has not been updated for a while, hope it works anyhow).

 

[agraham]

Your latest link, despite its appearance, ends at the Mac .app download and still gives a 403 error.

 

[johnmie]

OK, but what kind of information would you like to be added there ?

Concepts. By that I mean e.g. context menu or various type of dialogs like B4Xdialog, Preferences Dialog etc. True you find lots of mentions and some code snippets in the forum, but neophytes like me would typically first search through your booklets to find step-by-step instructions or complete examples.

 

[Pellmell]

Detailed instructions! things like initials also have notes, which is great. Thanks for sharing

To me, this looks more like a wish for a new booklet rather than with metadata.

 

[johnmie]

correct, happy New Year!

Hi Klaus,

Thank you so much for sharing the booklet in PDF format. It helps me a lot.

 

[Erel]

Version 2.3 of the booklets is now online. Thank you Klaus!

Note that the online guides links have changed as the previous service that was used is no longer available. The good news is that the links now work properly in the online version.

[jerry07]

FYI
B4X Basic Language booklet resolves to 404 page.

 

[Erel]

Fixed. Thank you.

 

[klaus]

Erel was faster than I.
I was about to mail him because of the links to the online booklets.
Whats new in edition 2.3:
- Added a specific chapter in the B4X VisualDesigner booklet: 3.17 Designer Script Extension / DesignerUtils Class
- Most of the projects have been converted into B4XPages projects.
- The links in the first page, for the online booklets, have been updated.

 

[klaus]

Erel, with the new online booklets it seems that it is no more possible to define a link for a specific page like before.
I had added quite some links in the booklets referring to a specific page in a given booklet.
Old method:
https://www.b4x.com/guides/BookletName/?page=xx
New method ?
I think that edition 2.4 will be needed soon, because of the change of the links.

PS: Could you please change the name of the B4X Basic Language booklet into B4X Language in the Documentation pages.
This name change was the problem with the link reported by jerry07.

 

[agraham]

The PDF download archive appears to be all v2.2 still!

 

[klaus]

I noticed it too.
I was about to investigate if it was a problem of refreshing the web page or not.
I seems that the archive has the old zip file.
