'Load .scl' and 'Load .kbm' function inconsistently

I've encountered the same bug as sourceforge #168. Certain directories of .scl files will display their contents sometimes and some have never displayed their contents. I've considered all responses to sourceforge #168 none of which are relevant. Any expertise related to the functions in question would be welcomed!

So, issues with the file browser are either in zynaddsubfx's MiddleWare.cpp file (IIRC) as that should be where the file lists are run or they are likely in https://github.com/mruby-zest/mruby-zest/blob/master/mrblib/file-browser.rb which houses the logic and some unit tests. The view itself is https://github.com/mruby-zest/mruby-zest/blob/master/example/FileSelector.qml . I know there's still some unresolved issues with regards to filesystem path string encoding on windows, though I was never able to fully replicate those issues when I tried it out on local systems.

[thenorili]

I've got both the 'file' files open already! I'll take a look at MiddleWare.cpp very soon since the error messages sound like an error in transmission to the backend to me.

Just so you know, I'm running Debian.

Tangentially, when I use the 'favorites' function to navigate to a path there isn't a '..' option which makes me quite stuck.

[thenorili]

I can access the microtonal files just fine in the FLTK UI though! Perhaps if I look at how it interacts with MiddleWare.cpp, I can find out how Zest should be interacting with it.

[fundamental]

The FLTK UI and the Zest file browsers work in fairly different manners. Performance on one isn't particularly indicative of the other in that capacity unfortunately. Also, if you're debugging what's sent between the backend and zest UI I'd recommend getting oscprompt hooked up (or a similar osc send/receive combo) if you haven't already.

[thenorili]

How do I determine what port zynaddsubfx owns? I can't find that information with top or /etc/services.

[fundamental]

When starting zyn (standalone) use the -P option to set the port number.

[thenorili]

I don't see any port corresponding to file_list_dirs, file_list_files, or load_scl. Even when I successfully load a .scl file, I'm seeing complete radio silence from the backend.

As you can see, I've found ports related to the intention of importing .scl and .kbm objects, but none of them are being used by zest.

[fundamental]

There's a few places where the metadata isn't immediately available in oscprompt, though messages can still be sent/received.

On zyn's side https://github.com/zynaddsubfx/zynaddsubfx/blob/master/src/Misc/MiddleWare.cpp#L1365-L1402 should be what the file browser is querying. e.g.

 /file_list_files "/tmp"
