There have been numerous deprecation warnings for nice tkd library: https://github.com/nomad-software/tkd and with the current ldc 1.27.1 it fails to build.

Since the repo is archived now how can we keep the library alive? Is it up to the person whoever forks it and then keeps a working copy of it? What about the corresponding dub package page? Is there a defined process or anything about the potential handover?
For example, I could keep a working fork for myself but updating it for the dub would be even better. What do you think?

Recent version for nullable removed implicit conversion, you must call .get now.. wich is a pain to update

i suggest using a previous version of struct Nullable https://github.com/dlang/phobos/blob/v2.096.1/std/typecons.d

create a nullable.d file in tkd project, and replace the imports to that module

that'll solve this issue

but that wouldn't solve the fact that the https://code.dlang.org/packages/tkd package won't build

we need to contact the maintainers and suggest to update the library

another solution would be to revert the nullable change

that sounds like an unnecessary change that breaks lot of code/packages..

Yes, I can locally "fix" that but I would also like whoever wants to compile the app in the company also compile it for his machine :(
I tried to find the email of the maintainer but so far didn't have time for search.

What you should probably do anyways is:

1- fork the project on github

2- apply the workaround for nullable

Update your dub file so it picks your dependency (people forgot, but you can use git repo as dependencies, just like in go)

	"repository":"https://github.com/your_github/tkd.git",
	"dependencies": {
		"tkd":  "~master" // or what ever version you want
	}

But ultimately, if the repo is archived, that means it is not maintained anymore

The licence is MIT, so you can fork it and maintain a new updated version, at least an updated one that compiles

github repos marked as "archived" should be reflected in the code.dlang.org page, dub should also display a warning when compiling an archived package in my opinion

Thank you. I have contacted him via LinkedIn and he unarchived the repo so I could push a PR. The PR is now merged and a new tkd version 1.1.14 is available via dub. This version is compatible with the recent dmd. All good.
