[vcpkg upgrade] Give vcpkg list output format which will be suitable for vcpkg install command.

[pravic]

Without doubt vcpkg upgrade is a great step forward, but we have sort of inconvenience now if upgrade fails for some reason. In that case we end up with uninstalled old libraries and partly installed the new ones.

Although vcpkg upgrade tells what it is going to update, but that list is not convenient to use for retry. I wish there was an additional output of the upgrade command, which would tell you how to properly continue or retry upgrade (basically a ready-to-copy list of libraries which can be pasted as an input for install).

Or, may be, upgrading should be atomic in ideal world.

@ras0219-msft:

We did previously have this list as the final output of the vcpkg update command; it was something of the form "vcpkg install openssl:x64-windows openssl:x64-window-static boost:x64-window-static boost:x64-windows .........".

That would be useful indeed. Or some way to tell vcpkg list to print installed libraries in a suitable way for vcpkg install would be better? So in this case I'd just backup installed libraries. And it's nice to share your list of libraries to your colleagues or to move it between your computers.

Ideas are welcome!

How about a .retry to keep the list ? And a command --skip-failed to skip some failed pkgs and their dependencies.

I think vcpkg should copy pip a bit, so that something like pip freeze > requirements.txt and pip install -r requirements.txt is possible.

This issue hasn’t been updated in a year; if it is still an issue, please reopen.

[horenmar]

What is there to update? Does vcpkg support usage similar to pip freeze and install from file? If yes, close the issue as implemented. If not, the feature is still unimplemented.

[pravic]

if it is still an issue, please reopen.

It is an issue. Why close?

[BillyONeal]

@pravic Because there are a lot of bogus stale issues, closing them is a means of poking to see if the issue was valid and/or people still care.

[pravic]

If it's a bogus issue, why bother at all? Close immediately and mark as invalid or wontfix.

[BillyONeal]

@pravic It was a bulk operation, not a targeted one.
