Different icons for application/file extension with same name on macOS and Windows

[iffy]

• Version: ^13.6.0

• Target: Mac/Win/Linux

My application is named LHTML and the file extensions it knows about are lhtml (same but lowercase).

Here's the pertinent parts of my package.json:

{
  "name": "lhtml",
  "productName": "LHTML",
  ...
  "build": {
    ...
    "fileAssociations": [
      {
        "ext": "lhtml",
        "role": "Editor",
        "icon": "build/lhtmldoc.icns"
      }
    ],
    ...
  },
}

So I have these icons:

• build/icon.icns (macOS application icon)
• build/icon.ico (Windows application icon)
• build/lhtmldoc.icns (macOS .lhtml document icon)
• build/lhtmldoc.ico (Windows .lhtml document icon)

I don't have a way of specifying the .lhtml document icon for both Windows and macOS.

I propose supporting something like:

    "fileAssociations": [
      {
        "ext": "lhtml",
        "role": "Editor",
        "icon": "build/lhtmldoc.${iconExt}"
      }
    ],

Why you cannot name file as lhtml.icns?

because the app's icon is Contents/Resources/LHTML.icns and if the file icon is lhtml.icns it can put it at Contents/Resources/lhtml.icns because my filesystem won't allow it

I'm trying to do the same. My app has an icon and I want a different icon for my fileAssociations (same icon for Windows and OS X). Is this already possible?

@matiastucci yes; here's how I did it: https://github.com/iffy/lhtml/blob/master/package.json#L54
