Unsaved files should be preserved on quit (hot exit)

[dgileadi]

Mac OSX 10.10.5 Yosemite, VS Code 0.10.1

Modern apps have a convention of not losing changes when the application quits and files haven't been explicitly saved. Sublime Text is particularly nice in this regard, where newly created or unsaved files are silently preserved on quit and restored when it is launched again. This would be nice for VS Code to support as well.

To Reproduce

1. Make changes to a file, or create a brand new unsaved file
2. Quit VS Code

Desired Behavior

VS Code immediately quits with no prompt. After relaunching the changed file is restored with changes intact and an unsaved indicator.

Actual Behavior

VS Code prompts you to save the file or discard your changes.

FYI : I'm become a big fan of this after computer suddenly hangup/lost power/cats hit shutdown button/etc and everything get restore after reopen.

That's why I'm not uninstall Sublime yet tho.

+1 I occasionally need to exit my editor quickly and like not having to think about saving when I do.

Would love to have this too. Very useful for scratch buffers and crash recovery.

+1 would love to have this feature too - for the same reasons elad mentioned. Actually not having this feature makes me using Sublime again.

     From  Sublime Text, Preferences

    // Exiting the application with hot_exit enabled will cause it to close
    // immediately without prompting. Unsaved modifications and open files will
    // be preserved and restored when next starting.
    //
    // Closing a window with an associated project will also close the window
    // without prompting, preserving unsaved changes in the workspace file
    // alongside the project.
    "hot_exit": true,

Quite frankly the hot_exit feature of SublimeText is so important to me
That I won't even consider another editor that doesn't have the feature.

One reason this is the case, is my machine sometimes doesn't come out of sleep
so I just do a forced reboot - no problem as all of my changes will be preserved.

Also note: the hot_exit feature also preserves the undo stack for each file
this is quite valuable.
