Machine-sensitive tab labels, show \\Server\Share\Parent\Path as 'Server-Path'

Buttons/Scripts

What is it?

This script makes identifying tabs on remote machines in LAN a bit easier,
by inserting the machine name and/or a Unicode symbol into the tab label.
E.g. if you open \\MyGamingRig\Games\Diablo2
the tab label will show MyGamingRig-Diablo2.

All machines in my LAN have similar/identical directory structures.
It gets often confusing to recognize to which machine
the "Temp" or "Downloads" or "DigiMusic" tab belongs.
I could not find a similar script, so I cooked up this little one.

There is no customization UI nor will be.
If you need to adjust the logic, see setMachineSensitiveTabLabel().

It reacts to folder changes, stored lister layouts, etc.
On local paths, it simply shows default DOpus label.

It looks like this:

# Unicode Icons
DO does not allow to set custom tab icons, yet,
but if you set Tab font to Segoe UI Emoji/Symbol or alike
in the preferences, you can insert a unicode symbol.

For emojis beyond FFFF, e.g. 1F989 (owl),
you need to use a so-called surrogate pair (SP), e.g. \uD83E\uDD89.
To get the SP code, use the form at the bottom of:
https://datacadamia.com/data/type/text/surrogate

SP calculation logic from the link above:
function surrogateCalculator(S){
   H = Math.floor((S - 0x10000) / 0x400) + 0xD800;
   L = ((S - 0x10000) % 0x400) + 0xDC00;
   return [H,L];
}
function printSurrogatePair(codePoint){
   let [H,L] = surrogateCalculator(codePoint);
   let outputText = 'The UTF16 surrogate pair for '+codePoint+' is \\u'+H.toString(16).toUpperCase()+'\\u'+L.toString(16).toUpperCase()+' ('+String.fromCodePoint(codePoint)+')';
   console.log(outputText);
}
Note: String.fromCodePoint() does not work in JScript!
