I'm very confused about these new project files. I have a .prj file that I've used for ages to package my code into a .mltbx file. With 19a we have what looks like a different sort of project file, also with the .prj extension. They do have different icons in the MATLAB file browser, but the documentation seems to treat the term "project file" interchangeably.
The new project file seems like a useful improvement, it knows all about the project, what files are included etc. I don't see why we need both kinds of project file.
If I use the programmatic interface (matlab.addons.toolbox.packageToolbox) to package my toolbox it will only work with the first sort of .prj file, not the second sort - that generates the error message "Invalid MATLAB toolbox project".
- is it proper to call both of these file types "project files"? The documention does.
- when adding or subtracting files to my project do I have to update both files? The 19a project file can export the sort of project file that can be used for packaging (ToolboxPackagingConfiguration.prj), but that exported file is missing all the metadata (image, author, description etc.) which should logically live in the 19a style project file.
- what's the rationale for having two files? Could all the information about my project, including how to package it (ie. the metadata) live in the one file?
