The npm semantic versioning utility\.

As a command\-line utility:

$ npm install semver \-g

Usage: semver \-v <version> [\-r <range>]
|
|
Test if version(s) satisfy the supplied range(s),
|
|
and sort them\.
|
|
Multiple versions or ranges may be supplied\.
|
|
Program exits successfully if any valid version satisfies
|
|
all supplied ranges, and prints all satisfying versions\.
|
|
If no versions are valid, or ranges are not satisfied,
|
|
then exits failure\.
|
|
Versions are printed in ascending order, so supplying
|
|
multiple versions to the utility will just sort them\.

A version is the following things, in this order:

a number (Major)

a number (minor)

OPTIONAL: a hyphen, followed by a number (build)

The ordering of versions is done using the following algorithm, given
|
|
two versions and asked to find the greater of the two:
|
|
.
|

.IP "\(bu" 4

If the majors are numerically different, then take the one
|
|
with a bigger major number\. \fB2\.3\.4 > 1\.3\.4\fR
|

.IP "\(bu" 4

If the minors are numerically different, then take the one

with the bigger minor number\. \fB2\.3\.4 > 2\.2\.4\fR

If the patches are numerically different, then take the one with the

bigger patch number\. \fB2\.3\.4 > 2\.3\.3\fR
|

.IP "\(bu" 4
|

If only one of them has a build number, then take the one with the
|
|
build number\. \fB2\.3\.4\-0 > 2\.3\.4\fR
|
|
.

.IP "\(bu" 4
|

If they both have build numbers, and the build numbers are numerically

different, then take the one with the bigger build number\. \fB2\.3\.4\-10 > 2\.3\.4\-9\fR

If only one of them has a tag, then take the one without the tag\. \fB2\.3\.4 > 2\.3\.4\-beta\fR

.IP "\(bu" 4

If they both have tags, then take the one with the lexicographically

larger tag\. \fB2\.3\.4\-beta > 2\.3\.4\-alpha\fR
