I do know that GOG Galaxy does provide full installer packages, I meant that if you download your games with the new download system, GOG does not guarantee stand-alone functionality if you zip the downloaded directory, transfer the zip file onto another computer without Galaxy, unpack it and try to start it. This was mentioned in the Alpha thread by some developers. You also can verify that by the Beneath a Steel Sky example.


Yes, we have to do some reverse engineering, if the protocol is not published.

I guess it depends where the downloaded files are placed. It can be client specific setting and not dictated by the protocol. In such case if you write a client which will put all files into some singular location, this can be avoided. All that can be left up to configuration I think. You don't need to mimic GOG client 1:1.

let me quote an answer from a dev in the Beta thread:

the only reason why games installed by Client are not trivially backupable yet is that the install script that is launched at the end of installation is not stored inside the installation folder to make it easy to re-launch it upon restoring that installation from whatever backup.

We plan to address during the beta, so every single of your installed games will be able to backed up at any time and by way you want, without any need to download the standalone installer.
from what I have read so far, it sounds as if they indeed move into the direction that quite a few wanted: just the game data + an installer script
if they then open up the API so that I can easily get that, then i would happily throw away the standalone installer.

I keep getting the following error when checking for orphans with version 2.21:

terminate called after throwing an instance of 'std::length_error'
what(): basic_string::replace
Aborted

The last line of output is "Getting game info 434 / 554"

I don't mind that as long this game directory is a self-contained and working WITHOUT GOG Galaxy installed. This is the whole point of my recent postings here.

Could you try current git version with this patch

Might be this gem that is doing it (star_wars_republic_commando_copy3 is - of course - jedi knight: dark forces 2):

$ lgogdownloader --download --game star_wars_republic_commando_copy3
terminate called after throwing an instance of 'std::length_error'
what(): basic_string::replace
Aborted

I don't think that patch helped.

Backtrace from gdb with debug build would be helpful

make debug
gdb ./bin/Debug/lgogdownloader
run --download --game star_wars_republic_commando_copy3

Thank you for the backtrace.
Apparently the error isn't in the obvious place that I expected it to be.
I'm interested in the output with this patch
https://sites.google.com/site/gogdownloader/catch_length_error_v2.diff
It should give more info on what goes wrong with the string assignment and works around the issue by setting the file name to "fileid.zip"
Running release build with this patch should give enough info.

Good. I forgot to mention that you should remove those.

Looks like the API call failed to get the url.
Try this patch
https://sites.google.com/site/gogdownloader/extras_redirect_location.diff
It should fix the problem by getting the url from redirect location of account page download link.
