B4J Question Comments in a B4xlib Manifest file.

stevel05 · May 5, 2023

Is it possible to add comments to the B4xlib manifest file? I would like to store some information like which project the library came from, creation date etc. I may generate a b4xlib from 1 module in a large project and don't really want to create a new project for the purpose so it's obvious.

You can put comments in a XML file the same way as in HTML: 
The comments can span multiple lines. You can't use 2 dashes -- in the comments.
The manifest editor (B4A) uses single quotes as comments and these comments don't appear in the manifest.xml file.
You can of course change the manifest.xml file yourself.

Thanks Paul, but I'm asking about the Manifest file in a B4xLib, which is delimited plain text.

Sorry, i assumed that it was a XML file.
After reading this thread it became clear: XML generation tool

b4xlibs do not require an XML file. The IDE parses the packed code modules.

In the B4X CustomViews booklet at page 31 i read:

A B4X library is a simple zip file with the following structure:
• Code modules. All types are supported including Activities and Services.
• Files, including layout files.
• Optional manifest file with the following fields:
o Version
o Author
o DependsOn (list of required libraries), Supported Platforms. Fields can be shared
between the platforms or be platform specific.
o Comment: adds a comment to the library.
This comment will be shown in the Libraries Manager Tab.

It seems that the manifest file has a comment field...

Ahh OK thanks, I don't remember seeing that. But what I'm really after are private comments (as in code comment) that are just ignored.

Yes, you can add comments to the B4xlib manifest file. such as:

B4X:

Version=2.00
B4J.DependsOn=jXUI, jDateUtils
B4A.DependsOn=XUI, DateUtils
B4i.DependsOn=iXUI, iDateUtils
Your comments.....

Thanks @teddybear I'll give it a go.
I could have just tried it, I thought that maybe there was a designated character for the parser to ignore.

The manifest parser ignores invalid lines though it is better to start comments with apostrophe:

B4X:

'comment here. The equal sign will not cause an error = jklfdsjflksd
