Feature request: targets.docs.deps and targets.benchmark.deps

[tkf]

It would be nice to have targets.docs.deps and targets.benchmark.deps, etc. (or docs/Project.toml and benchmark/Project.toml somehow stacked on top of the root Project.toml) for document- and benchmark- specific dependencies. Are you planning to add such features?

It may be related to #480 since I guess those features will share the implementation.

You can add these deps to [extras] and then have targets.banchmark = [...] to list the packages you want in this target. What do you imagine that this target would mean to the package manager?

Yes, I saw you wrote #531 so I thought it was solved and closed it (probably should have commented that).

What do you imagine that this target would mean to the package manager?

I thought the best answer would be nothing in the sense that the environments for ./docs, ./benchmark and ./test are yet another environment with extra packages on top of [deps] and the package manager doesn't care what it's for. From what I understand from the PR, it looks like your design of [extras] and [targets] covers arbitrary targets so that looks great. What is not clear for me at the moment is the way to activate one of [targets] (as already mentioned in #480 (comment)) but I suppose that's more like julia issue? Ideally, I'd like to do something like pkg> activate @:docs in REPL or julia --project=@:docs docs/make.jl from shell to activate docs target in current project @ (completely made-up syntax).
