Usage: semver <version> [<version> [\.\.\.]] [\-r <range> | \-i <inc> | \-d <dec>]
|
|
Test if version(s) satisfy the supplied range(s), and sort them\.
|
|
Multiple versions or ranges may be supplied, unless increment
|
|
or decrement options are specified\. In that case, only a single
|
|
version may be used, and it is incremented by the specified level
|
|
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 leading \fB"="\fR or \fB"v"\fR character is stripped off and ignored\.

.SH "Ranges"
|

The following range styles are supported:
|
|
.
|
|
.IP "\(bu" 4
|
|
\fB1\.2\.3\fR A specific version\. When nothing else will do\. Note that
|
|
build metadata is still ignored, so \fB1\.2\.3+build2012\fR will satisfy
|
|
this range\.
|
|
.
|
|
.IP "\(bu" 4
|
|
\fB>1\.2\.3\fR Greater than a specific version\.
|
|
.
|
|
.IP "\(bu" 4
|
|
\fB<1\.2\.3\fR Less than a specific version\. If there is no prerelease
|
|
tag on the version range, then no prerelease version will be allowed
|
|
either, even though these are technically "less than"\.
|
|
.
|
|
.IP "\(bu" 4
|
|
\fB>=1\.2\.3\fR Greater than or equal to\. Note that prerelease versions
|
|
are NOT equal to their "normal" equivalents, so \fB1\.2\.3\-beta\fR will
|
|
not satisfy this range, but \fB2\.3\.0\-beta\fR will\.
|
|
.
|
|
.IP "\(bu" 4
|
|
\fB<=1\.2\.3\fR Less than or equal to\. In this case, prerelease versions
|
|
ARE allowed, so \fB1\.2\.3\-beta\fR would satisfy\.

\fB~1\.2\.3\fR := \fB>=1\.2\.3\-0 <1\.3\.0\-0\fR "Reasonably close to 1\.2\.3"\. When
|
|
using tilde operators, prerelease versions are supported as well,
|

but a prerelease of the next significant digit will NOT be

satisfactory, so \fB1\.3\.0\-beta\fR will not satisfy \fB~1\.2\.3\fR\|\.

Ranges can be joined with either a space (which implies "and") or a \fB||\fR (which implies "or")\.

.SH "Functions"
|
|
All methods and classes take a final \fBloose\fR boolean argument that, if
|
|
true, will be more forgiving about not\-quite\-valid semver strings\.
|
|
The resulting output will always be 100% strict, of course\.
|
|
.
|
|
.P
|
|
Strict\-mode Comparators and Ranges will be strict about the SemVer
|
|
strings that they parse\.
|
|
.
|
|
.IP "\(bu" 4
|
|
valid(v): Return the parsed version, or null if it\'s not valid\.
|
|
.
|
|
.IP "\(bu" 4
|
|
inc(v, release): Return the version incremented by the release type
|
|
(major, minor, patch, or prerelease), or null if it\'s not valid\.

cmp(v1, comparator, v2): Pass in a comparison string, and it\'ll call

string comparison, but are included for completeness\. Throws if an
