Non-Windows support

[jrr]

This tool only works on Windows. This makes me sad.

I'll try to find time to work on this in the next week or so, if you'd welcome a PR.

Hi. I just published 1.0.4 which I think will work on Mac and Linux, please give it a try.

Argh. Looks like my attempt at identifying the operating system was wrong, and also my failure to remove the Windows-only check in Program.cs.

Programming is hard.

Just published 1.0.5 which definitely fixes one of those bugs, and hopefully fixes the other, although I can't test it because I don't have anything but Windows boxes to play with.

Sorry, man

So, I just noticed "Tools -> Create Command-Line Launcher..." built right in to Rider, which I think is good enough for my needs. Out of curiosity, what led you to create this tool? @markrendle

[vasily-kirichenko]

@jrr Rider does not have that menu item on Windows :)

[ThatRendle]

@jrr Yeah, it's not available in Windows, which is why this was originally a Windows-only tool. But a few people asked for it to be x-plat.

[ThatRendle]

@vasily-kirichenko I don't suppose you'd consider cloning this repo and step-debugging on your Linux box for me? 😊

[vasily-kirichenko]

:) You mean, my Mac box :) Let me try.

/Users/vaskir/Library/Application Support/JetBrains/Toolbox/.settings.json does exist, but it does not contain install_location:

{
  "autostart": true,
  "jba": {
    "email": "xxx@gmail.com",
    "fullName": "me",
    "login": "mylogin"
  },
  "privacy_policy": {

  },
  "proxy": {},
  "statistics": {
    "allow": true

  "ui": {
    "hotkey": ""

}
