Readme: Semver Compatibility? about registry HOT 6 CLOSED

@speigg we apply the semver range - which is defined as https://github.com/npm/node-semver#caret-ranges-123-025-004.

r71 won't apply to r70 because it isn't a valid semver. Major versions don't count. Also prereleases don't count either.

Hmm. That doesn't really answer my questions. I understand how semver compatability works, just not what it's role is with overrides. the main thing I'm tying to figure out: if an old override is compatible with a newer version of a library (not semver compatible necesarilly but functionally compatible) does it need to be updated in the registry every time there is a new version of the package?

For example, let's say we have an override for package X version 0.0.1 in the registry. Is this override used in each of the following situations?

jspm install [email protected]
jspm install [email protected]
jspm install [email protected]

The answer (still) isn't clear to me.

Right, so an override at version 0.0.1 will only apply for version 0.0.1. An override at 0.1.5 will apply for all >=0.1.5<0.2.0-. And an override at 1.0.0 will apply for all <2. Prereleases are excluded, although perhaps we should consider allowing them actually.

Okay thanks for clarifying, but that doesn't really make sense to me.

Assuming that an override for version 0.1.5 would apply for all >=0.1.5<0.2.0

Wouldnt an override for version 0.0.1 apply for all >=0.0.1<0.1.0 ?

Likewise, wouldn't an override for version 1.0.0 apply for all >=1.0.0<1.1.0 ?

I believe the above is what you meant to say. If so, that means overrides are currently tied to the minor version number.

No, the ranges I've given are the ranges defined by semver (https://github.com/npm/node-semver#caret-ranges-123-025-004).

The reason everyone publishes version 1 from day 1 is exactly because of this fact that the ranges are reduced below 1, and everyone gets confused about it. It's a pretty simple rule though - we just need someone to share the actual info clearly.

Okay, I think I understand now. Thanks for explaining.
