Allow opting out of clap default features.

[ski-csis]

Clap comes with some colorful default features, which are not always useful or wanted, so allow opting out of them.

Thanks for the contribution!

I'm not a cargo feature wizard, thus I have a few questions:

• is the default the same as before? (I suspect yes)
• How can you cherry-pick clap feature forward structopt? (a note in the documentation about that would be a great addition).

[ski-csis]

Yup, this leaves the default unchanged (just checked with a fresh test-crate for good measure :).

I added a note on how to disable the color-stuff in the README, was that where you meant?

[TeXitoi]

Mmm, thus, or you desactivate everything, or nothing? You can't desactivate color but activate suggestions?

[ski-csis]

I can add features here like:

clap-color = ["clap/color"]
clap-suggestions = ["clap/suggestions"]

Then you can use default-features = false, features = ["clap-color"] to get color w/o suggestions.

But, do you think it's likely anyone would use that?

[TeXitoi]

That may be overkill. Let's do it simple first.

[TeXitoi]

If you want to disable all the clap features (color, suggestions...), add [...]

I would prefer this doc to be in src/lib.rs than in README.md.

After that, I'll merge it.

Thanks!

Like this?

Thanks!

0.1.7 published

How do I enable them tho? I read its "on by default" but I don't see colors nor suggestions.

[dependencies]
structopt = "0.3"

[CreepySkeleton]

Weird they should be on.

Try

[dependencies]
structopt = { version = "0.3", features = ["color", "suggestions"] }

[shilangyu]

Nope, nothing. I don't want to spam anymore here, I'll open a separate issue, just last question: Was I supposed to turn on the features explicitly in rust code? Or including them in Cargo.toml is supposed to be all?
