There was a problem hiding this comment. nodejs doesn't have a built-in date formating function? There was a problem hiding this comment. Not one for formatting it in a file-name-friendly way AFAIK.

There was a problem hiding this comment. for style points, we could call It is possible to unload and reload the extension without the process actually exiting. There was a problem hiding this comment. Earlier I confirmed that it cleared the temp file properly when closing the window or reloading the session/switching folders.
The main VSCode process doesn't exit, but the extension host does. Extensions are run in an independent sandboxed process which is restarted when you reload the window. |

Running from the command palette is actually broken here because there is no parameter passed as
dinBut some of the other commands are currently broken for the same reason, so we can leave this as is and fix them all later (I have a plan...).

Just looked at this again and this command should not be showing up in the command palette. Not sure what's up. Perhaps a vscode bug.
