I have a single-line label whose purpose is display file path, possibly very long.
Is there any way to shorten/compact the path string (with ellipse ...) so that the label still displays full path even it's too long?
Like below:
/some/very/long/path/to/some/filename.txt
to
/some/.../filename.txt
I don't think that can be done automatically.
What I would do:
In URL struct, you have pathComponents which gives you access to all components. From it, parse what you need (first and last).
Or you can use properties as:
Explanations in Xcode doc are useless. So have a look here for instance: https://cocoacasts.com/working-with-nsurlcomponents-in-swift
That can be done quite easily. But what I want is a more 'strict' way.
I'd like to know if Cocoa/Appket provide some low-level mechnisms to measure if a long string fit in a constrained rectangle when it's displayed in a graphics context (here, an NSTextField). When it's not fit entirely, I can abbreviate some path components to make the path string shorter.
I think you can set the label's line break mode to "Truncate Middle", so very long text automatically gets an ellipsis in the middle.
I'd like to know if Cocoa/AppKit
If you’re on the Mac, be aware that AppKit has NSPathControl.
Share and Enjoy
