packages - Is self-reference possible in MATLAB?

Question

As noted here, functions in packages, as well as static methods in classes, still need to use a packagename.functionname syntax or import packagename.* for each function (since the imports are part of the function workspace and not global). This means that changing the package/class name later on can become a tedious nuisance.

Is there any way to do something like import this.*, i.e. a package/class name agnostic method to access all functions/static methods in the same package/class?

Answer 1

So... doesn't this require importthis to also be imported? Or is importthis a function you always have in your path?

It seems hardly more complex to just paste an "import this" block with this at the top of each function, and then you don't have to worry about importthis being in your path. I tend to feel that reliance on path is dangerous.

"Import This" block

%% Import own package
[~, pkgdir] = fileparts(fileparts(mfilename('fullpath')));
import([pkgdir(2:end) '.*']);

You can even put it in a try/catch block to make sure it's in a package directory, and decide what to do if it's not.

%% Import own package
try
    [~, pkgdir] = fileparts(fileparts(mfilename('fullpath'))); 
    import([pkgdir(2:end)'.*']);
catch err
    if ~strcmp(err.identifier,'MATLAB:UndefinedFunction'), rethrow(err); end
end
