[nodejs] meaning of the semver ~

[Dominic Tarr]

without looking in the documentation or trying it in the repl

what do you expect to be the results of these tests on semver ranges?

A. semver.satisfies('~1.2.3', '1.2.4')

B. semver.satisfies('~1.2', '1.3.0')

C. semver.satisfies('~1.2', '1.2.6')

D. semver.satisfies('1.2', '1.3.0')

E. semver.satisfies('1.2', '1.2.4')

please don't look at the documentation, the question is:

what do you think it means?

true-y

falsy

My intuitive understanding (which is probably wrong) is that "~1.2.3" -> "1.2.x" -> "1.2.0 <= version < 1.3". That said, '~' feels squishy to me, so I tend to prefer "1.2.x".

I'd prefer to be very explicit:

>=1.2.0 <2.0.0

I read this as "allow version 1.2.0 or any subsequent version prior to a major API change."

I think this is what the tilde implies, but I would have to look it up more than once… and so would my fellow collaborators, I imagine.

A. semver.satisfies('~1.2.3', '1.2.4') => true
B. semver.satisfies('~1.2', '1.3.0') => false
C. semver.satisfies('~1.2', '1.2.6') => true
D. semver.satisfies('1.2', '1.3.0') => false
E. semver.satisfies('1.2', '1.2.4') => true

My understanding is similar to Forrest's. ~1.2.3 means 1.2.3 <= version < 1.3.0, whereas ~1.2 means 1.2.0 <= version < 1.3.0

With Forrest's explanation, semver.satisfies('~1.2.3', '1.2.1') would be true, whereas I would expect it to be false. +1 for the "squishiness", however, but I prefer that as an indicator to NPM that patch updates are acceptable while still guaranteeing all the patches in 1.2.3 are present.

[Tim Smart]

A - true
B - true
C - true
D - false
E - true

Time to look at the documentation :)

[Isaac Schlueter]

Also: No looking at the code or running the semver command line util ;)

[Alan Gutierrez]

A. Yes.
B. No.
C. Yes.
D. No.

'cause you submitted the arguments in a wrong order. ;)

[chakrit]

A. YES

B. NO

C. YES

D. NO

E. YES

[chakrit]

Meaning:

A: Around this version, so get the most recent version that's still not too far from 1.2

B: 1.3 might have API changes, don't want it. I have programmed against 1.2 so let's stick to that for the moment

C: Around this version, like A

D: 1.2 with whatever patch version's available but not definitely not 1.3

E: like D

A. semver.satisfies('~1.2.3', '1.2.4')

True, because 1.2.3 seems to be approximately 1.2.4 

B. semver.satisfies('~1.2', '1.3.0')

False, since 1.3.0 is not approximately 1.2

C. semver.satisfies('~1.2', '1.2.6')

True.

 

D. semver.satisfies('1.2', '1.3.0')

True, since I assume that 1.3.0 is 1.2.x and more.

 

E. semver.satisfies('1.2', '1.2.4')

True again.

 

please don't look at the documentation, the question is:

~1.2.3 probably means a version around 1.2.3 with the rev. possibly different. I expect only revisions >= 3 to match though.
