In my work environment access to the internet is forbidden for the official build due to software lifecycle requirements. The consequence is that I have to fetch all dependencies into the dub project (--cache = local). In addition every time open source software is used, for each open source software product a process has to be fulfilled. As example I would like to use the unit test framework d-unit. This dub package has for a specific configuration a decency to unit-threaded. The official build will fail as unit-threaded can not be found (no internet access). Including unit-threaded is not an option due to the open source process. Doing this process for the sake of a dub issue is not acceptable. There is an additional dub build option --nodeps. In my opinion this option should solve the problem but it is not working as expected. Maybe to due a bug. I created dub issue 1272 regarding this issue. Kind regards Andre

I'd like dub fetch vibe-d only when I build with --config vibed. As far as I know, that isn't possible. A package is either optional, or it isn't. It certainly would be a useful feature to have. Perhaps create an enhancement request for it if there isn't one already. https://github.com/dlang/dub/issues

dub optional dependency
Hello,
I have dub.json with two configurations:
"configurations": [
{
"name": "std",
"targetType": "library"
},
{
"name": "vibed",
"dependencies": {
"vibe-d": {"version": "~>0.7"}
},
"targetType": "library",
"versions": [
"vibeD"
]
}
],
So default version is "std", I can build it w/o vibe-d, but dub
anyway fetch vibe-d.
I'd like dub fetch vibe-d only when I build with --config vibed.
I know about "optional": true, it prevent dub to fetch vibe-d for
"std" config, but it also prevent it from fetching for --config
vibed.
Thanks for any help.
