semver(1) -- The semantic versioner for npm
 | 
			
		||||
===========================================
 | 
			
		||||
 | 
			
		||||
## Install
 | 
			
		||||
 | 
			
		||||
```bash
 | 
			
		||||
npm install --save semver
 | 
			
		||||
````
 | 
			
		||||
 | 
			
		||||
## Usage
 | 
			
		||||
 | 
			
		||||
As a node module:
 | 
			
		||||
 | 
			
		||||
```js
 | 
			
		||||
const semver = require('semver')
 | 
			
		||||
 | 
			
		||||
semver.valid('1.2.3') // '1.2.3'
 | 
			
		||||
semver.valid('a.b.c') // null
 | 
			
		||||
semver.clean('  =v1.2.3   ') // '1.2.3'
 | 
			
		||||
semver.satisfies('1.2.3', '1.x || >=2.5.0 || 5.0.0 - 7.2.3') // true
 | 
			
		||||
semver.gt('1.2.3', '9.8.7') // false
 | 
			
		||||
semver.lt('1.2.3', '9.8.7') // true
 | 
			
		||||
semver.valid(semver.coerce('v2')) // '2.0.0'
 | 
			
		||||
semver.valid(semver.coerce('42.6.7.9.3-alpha')) // '42.6.7'
 | 
			
		||||
```
 | 
			
		||||
 | 
			
		||||
As a command-line utility:
 | 
			
		||||
 | 
			
		||||
```
 | 
			
		||||
$ semver -h
 | 
			
		||||
 | 
			
		||||
A JavaScript implementation of the http://semver.org/ specification
 | 
			
		||||
Copyright Isaac Z. Schlueter
 | 
			
		||||
 | 
			
		||||
Usage: semver [options] <version> [<version> [...]]
 | 
			
		||||
Prints valid versions sorted by SemVer precedence
 | 
			
		||||
 | 
			
		||||
Options:
 | 
			
		||||
-r --range <range>
 | 
			
		||||
        Print versions that match the specified range.
 | 
			
		||||
 | 
			
		||||
-i --increment [<level>]
 | 
			
		||||
        Increment a version by the specified level.  Level can
 | 
			
		||||
        be one of: major, minor, patch, premajor, preminor,
 | 
			
		||||
        prepatch, or prerelease.  Default level is 'patch'.
 | 
			
		||||
        Only one version may be specified.
 | 
			
		||||
 | 
			
		||||
--preid <identifier>
 | 
			
		||||
        Identifier to be used to prefix premajor, preminor,
 | 
			
		||||
        prepatch or prerelease version increments.
 | 
			
		||||
 | 
			
		||||
-l --loose
 | 
			
		||||
        Interpret versions and ranges loosely
 | 
			
		||||
 | 
			
		||||
-p --include-prerelease
 | 
			
		||||
        Always include prerelease versions in range matching
 | 
			
		||||
 | 
			
		||||
-c --coerce
 | 
			
		||||
        Coerce a string into SemVer if possible
 | 
			
		||||
        (does not imply --loose)
 | 
			
		||||
 | 
			
		||||
Program exits successfully if any valid version satisfies
 | 
			
		||||
all supplied ranges, and prints all satisfying versions.
 | 
			
		||||
 | 
			
		||||
If no satisfying versions are found, then exits failure.
 | 
			
		||||
 | 
			
		||||
Versions are printed in ascending order, so supplying
 | 
			
		||||
multiple versions to the utility will just sort them.
 | 
			
		||||
```
 | 
			
		||||
 | 
			
		||||
## Versions
 | 
			
		||||
 | 
			
		||||
A "version" is described by the `v2.0.0` specification found at
 | 
			
		||||
<http://semver.org/>.
 | 
			
		||||
 | 
			
		||||
A leading `"="` or `"v"` character is stripped off and ignored.
 | 
			
		||||
 | 
			
		||||
## Ranges
 | 
			
		||||
 | 
			
		||||
A `version range` is a set of `comparators` which specify versions
 | 
			
		||||
that satisfy the range.
 | 
			
		||||
 | 
			
		||||
A `comparator` is composed of an `operator` and a `version`.  The set
 | 
			
		||||
of primitive `operators` is:
 | 
			
		||||
 | 
			
		||||
* `<` Less than
 | 
			
		||||
* `<=` Less than or equal to
 | 
			
		||||
* `>` Greater than
 | 
			
		||||
* `>=` Greater than or equal to
 | 
			
		||||
* `=` Equal.  If no operator is specified, then equality is assumed,
 | 
			
		||||
  so this operator is optional, but MAY be included.
 | 
			
		||||
 | 
			
		||||
For example, the comparator `>=1.2.7` would match the versions
 | 
			
		||||
`1.2.7`, `1.2.8`, `2.5.3`, and `1.3.9`, but not the versions `1.2.6`
 | 
			
		||||
or `1.1.0`.
 | 
			
		||||
 | 
			
		||||
Comparators can be joined by whitespace to form a `comparator set`,
 | 
			
		||||
which is satisfied by the **intersection** of all of the comparators
 | 
			
		||||
it includes.
 | 
			
		||||
 | 
			
		||||
A range is composed of one or more comparator sets, joined by `||`.  A
 | 
			
		||||
version matches a range if and only if every comparator in at least
 | 
			
		||||
one of the `||`-separated comparator sets is satisfied by the version.
 | 
			
		||||
 | 
			
		||||
For example, the range `>=1.2.7 <1.3.0` would match the versions
 | 
			
		||||
`1.2.7`, `1.2.8`, and `1.2.99`, but not the versions `1.2.6`, `1.3.0`,
 | 
			
		||||
or `1.1.0`.
 | 
			
		||||
 | 
			
		||||
The range `1.2.7 || >=1.2.9 <2.0.0` would match the versions `1.2.7`,
 | 
			
		||||
`1.2.9`, and `1.4.6`, but not the versions `1.2.8` or `2.0.0`.
 | 
			
		||||
 | 
			
		||||
### Prerelease Tags
 | 
			
		||||
 | 
			
		||||
If a version has a prerelease tag (for example, `1.2.3-alpha.3`) then
 | 
			
		||||
it will only be allowed to satisfy comparator sets if at least one
 | 
			
		||||
comparator with the same `[major, minor, patch]` tuple also has a
 | 
			
		||||
prerelease tag.
 | 
			
		||||
 | 
			
		||||
For example, the range `>1.2.3-alpha.3` would be allowed to match the
 | 
			
		||||
version `1.2.3-alpha.7`, but it would *not* be satisfied by
 | 
			
		||||
`3.4.5-alpha.9`, even though `3.4.5-alpha.9` is technically "greater
 | 
			
		||||
than" `1.2.3-alpha.3` according to the SemVer sort rules.  The version
 | 
			
		||||
range only accepts prerelease tags on the `1.2.3` version.  The
 | 
			
		||||
version `3.4.5` *would* satisfy the range, because it does not have a
 | 
			
		||||
prerelease flag, and `3.4.5` is greater than `1.2.3-alpha.7`.
 | 
			
		||||
 | 
			
		||||
The purpose for this behavior is twofold.  First, prerelease versions
 | 
			
		||||
frequently are updated very quickly, and contain many breaking changes
 | 
			
		||||
that are (by the author's design) not yet fit for public consumption.
 | 
			
		||||
Therefore, by default, they are excluded from range matching
 | 
			
		||||
semantics.
 | 
			
		||||
 | 
			
		||||
Second, a user who has opted into using a prerelease version has
 | 
			
		||||
clearly indicated the intent to use *that specific* set of
 | 
			
		||||
alpha/beta/rc versions.  By including a prerelease tag in the range,
 | 
			
		||||
the user is indicating that they are aware of the risk.  However, it
 | 
			
		||||
is still not appropriate to assume that they have opted into taking a
 | 
			
		||||
similar risk on the *next* set of prerelease versions.
 | 
			
		||||
 | 
			
		||||
#### Prerelease Identifiers
 | 
			
		||||
 | 
			
		||||
The method `.inc` takes an additional `identifier` string argument that
 | 
			
		||||
will append the value of the string as a prerelease identifier:
 | 
			
		||||
 | 
			
		||||
```javascript
 | 
			
		||||
semver.inc('1.2.3', 'prerelease', 'beta')
 | 
			
		||||
// '1.2.4-beta.0'
 | 
			
		||||
```
 | 
			
		||||
 | 
			
		||||
command-line example:
 | 
			
		||||
 | 
			
		||||
```bash
 | 
			
		||||
$ semver 1.2.3 -i prerelease --preid beta
 | 
			
		||||
1.2.4-beta.0
 | 
			
		||||
```
 | 
			
		||||
 | 
			
		||||
Which then can be used to increment further:
 | 
			
		||||
 | 
			
		||||
```bash
 | 
			
		||||
$ semver 1.2.4-beta.0 -i prerelease
 | 
			
		||||
1.2.4-beta.1
 | 
			
		||||
```
 | 
			
		||||
 | 
			
		||||
### Advanced Range Syntax
 | 
			
		||||
 | 
			
		||||
Advanced range syntax desugars to primitive comparators in
 | 
			
		||||
deterministic ways.
 | 
			
		||||
 | 
			
		||||
Advanced ranges may be combined in the same way as primitive
 | 
			
		||||
comparators using white space or `||`.
 | 
			
		||||
 | 
			
		||||
#### Hyphen Ranges `X.Y.Z - A.B.C`
 | 
			
		||||
 | 
			
		||||
Specifies an inclusive set.
 | 
			
		||||
 | 
			
		||||
* `1.2.3 - 2.3.4` := `>=1.2.3 <=2.3.4`
 | 
			
		||||
 | 
			
		||||
If a partial version is provided as the first version in the inclusive
 | 
			
		||||
range, then the missing pieces are replaced with zeroes.
 | 
			
		||||
 | 
			
		||||
* `1.2 - 2.3.4` := `>=1.2.0 <=2.3.4`
 | 
			
		||||
 | 
			
		||||
If a partial version is provided as the second version in the
 | 
			
		||||
inclusive range, then all versions that start with the supplied parts
 | 
			
		||||
of the tuple are accepted, but nothing that would be greater than the
 | 
			
		||||
provided tuple parts.
 | 
			
		||||
 | 
			
		||||
* `1.2.3 - 2.3` := `>=1.2.3 <2.4.0`
 | 
			
		||||
* `1.2.3 - 2` := `>=1.2.3 <3.0.0`
 | 
			
		||||
 | 
			
		||||
#### X-Ranges `1.2.x` `1.X` `1.2.*` `*`
 | 
			
		||||
 | 
			
		||||
Any of `X`, `x`, or `*` may be used to "stand in" for one of the
 | 
			
		||||
numeric values in the `[major, minor, patch]` tuple.
 | 
			
		||||
 | 
			
		||||
* `*` := `>=0.0.0` (Any version satisfies)
 | 
			
		||||
* `1.x` := `>=1.0.0 <2.0.0` (Matching major version)
 | 
			
		||||
* `1.2.x` := `>=1.2.0 <1.3.0` (Matching major and minor versions)
 | 
			
		||||
 | 
			
		||||
A partial version range is treated as an X-Range, so the special
 | 
			
		||||
character is in fact optional.
 | 
			
		||||
 | 
			
		||||
* `""` (empty string) := `*` := `>=0.0.0`
 | 
			
		||||
* `1` := `1.x.x` := `>=1.0.0 <2.0.0`
 | 
			
		||||
* `1.2` := `1.2.x` := `>=1.2.0 <1.3.0`
 | 
			
		||||
 | 
			
		||||
#### Tilde Ranges `~1.2.3` `~1.2` `~1`
 | 
			
		||||
 | 
			
		||||
Allows patch-level changes if a minor version is specified on the
 | 
			
		||||
comparator.  Allows minor-level changes if not.
 | 
			
		||||
 | 
			
		||||
* `~1.2.3` := `>=1.2.3 <1.(2+1).0` := `>=1.2.3 <1.3.0`
 | 
			
		||||
* `~1.2` := `>=1.2.0 <1.(2+1).0` := `>=1.2.0 <1.3.0` (Same as `1.2.x`)
 | 
			
		||||
* `~1` := `>=1.0.0 <(1+1).0.0` := `>=1.0.0 <2.0.0` (Same as `1.x`)
 | 
			
		||||
* `~0.2.3` := `>=0.2.3 <0.(2+1).0` := `>=0.2.3 <0.3.0`
 | 
			
		||||
* `~0.2` := `>=0.2.0 <0.(2+1).0` := `>=0.2.0 <0.3.0` (Same as `0.2.x`)
 | 
			
		||||
* `~0` := `>=0.0.0 <(0+1).0.0` := `>=0.0.0 <1.0.0` (Same as `0.x`)
 | 
			
		||||
* `~1.2.3-beta.2` := `>=1.2.3-beta.2 <1.3.0` Note that prereleases in
 | 
			
		||||
  the `1.2.3` version will be allowed, if they are greater than or
 | 
			
		||||
  equal to `beta.2`.  So, `1.2.3-beta.4` would be allowed, but
 | 
			
		||||
  `1.2.4-beta.2` would not, because it is a prerelease of a
 | 
			
		||||
  different `[major, minor, patch]` tuple.
 | 
			
		||||
 | 
			
		||||
#### Caret Ranges `^1.2.3` `^0.2.5` `^0.0.4`
 | 
			
		||||
 | 
			
		||||
Allows changes that do not modify the left-most non-zero digit in the
 | 
			
		||||
`[major, minor, patch]` tuple.  In other words, this allows patch and
 | 
			
		||||
minor updates for versions `1.0.0` and above, patch updates for
 | 
			
		||||
versions `0.X >=0.1.0`, and *no* updates for versions `0.0.X`.
 | 
			
		||||
 | 
			
		||||
Many authors treat a `0.x` version as if the `x` were the major
 | 
			
		||||
"breaking-change" indicator.
 | 
			
		||||
 | 
			
		||||
Caret ranges are ideal when an author may make breaking changes
 | 
			
		||||
between `0.2.4` and `0.3.0` releases, which is a common practice.
 | 
			
		||||
However, it presumes that there will *not* be breaking changes between
 | 
			
		||||
`0.2.4` and `0.2.5`.  It allows for changes that are presumed to be
 | 
			
		||||
additive (but non-breaking), according to commonly observed practices.
 | 
			
		||||
 | 
			
		||||
* `^1.2.3` := `>=1.2.3 <2.0.0`
 | 
			
		||||
* `^0.2.3` := `>=0.2.3 <0.3.0`
 | 
			
		||||
* `^0.0.3` := `>=0.0.3 <0.0.4`
 | 
			
		||||
* `^1.2.3-beta.2` := `>=1.2.3-beta.2 <2.0.0` Note that prereleases in
 | 
			
		||||
  the `1.2.3` version will be allowed, if they are greater than or
 | 
			
		||||
  equal to `beta.2`.  So, `1.2.3-beta.4` would be allowed, but
 | 
			
		||||
  `1.2.4-beta.2` would not, because it is a prerelease of a
 | 
			
		||||
  different `[major, minor, patch]` tuple.
 | 
			
		||||
* `^0.0.3-beta` := `>=0.0.3-beta <0.0.4`  Note that prereleases in the
 | 
			
		||||
  `0.0.3` version *only* will be allowed, if they are greater than or
 | 
			
		||||
  equal to `beta`.  So, `0.0.3-pr.2` would be allowed.
 | 
			
		||||
 | 
			
		||||
When parsing caret ranges, a missing `patch` value desugars to the
 | 
			
		||||
number `0`, but will allow flexibility within that value, even if the
 | 
			
		||||
major and minor versions are both `0`.
 | 
			
		||||
 | 
			
		||||
* `^1.2.x` := `>=1.2.0 <2.0.0`
 | 
			
		||||
* `^0.0.x` := `>=0.0.0 <0.1.0`
 | 
			
		||||
* `^0.0` := `>=0.0.0 <0.1.0`
 | 
			
		||||
 | 
			
		||||
A missing `minor` and `patch` values will desugar to zero, but also
 | 
			
		||||
allow flexibility within those values, even if the major version is
 | 
			
		||||
zero.
 | 
			
		||||
 | 
			
		||||
* `^1.x` := `>=1.0.0 <2.0.0`
 | 
			
		||||
* `^0.x` := `>=0.0.0 <1.0.0`
 | 
			
		||||
 | 
			
		||||
### Range Grammar
 | 
			
		||||
 | 
			
		||||
Putting all this together, here is a Backus-Naur grammar for ranges,
 | 
			
		||||
for the benefit of parser authors:
 | 
			
		||||
 | 
			
		||||
```bnf
 | 
			
		||||
range-set  ::= range ( logical-or range ) *
 | 
			
		||||
logical-or ::= ( ' ' ) * '||' ( ' ' ) *
 | 
			
		||||
range      ::= hyphen | simple ( ' ' simple ) * | ''
 | 
			
		||||
hyphen     ::= partial ' - ' partial
 | 
			
		||||
simple     ::= primitive | partial | tilde | caret
 | 
			
		||||
primitive  ::= ( '<' | '>' | '>=' | '<=' | '=' ) partial
 | 
			
		||||
partial    ::= xr ( '.' xr ( '.' xr qualifier ? )? )?
 | 
			
		||||
xr         ::= 'x' | 'X' | '*' | nr
 | 
			
		||||
nr         ::= '0' | ['1'-'9'] ( ['0'-'9'] ) *
 | 
			
		||||
tilde      ::= '~' partial
 | 
			
		||||
caret      ::= '^' partial
 | 
			
		||||
qualifier  ::= ( '-' pre )? ( '+' build )?
 | 
			
		||||
pre        ::= parts
 | 
			
		||||
build      ::= parts
 | 
			
		||||
parts      ::= part ( '.' part ) *
 | 
			
		||||
part       ::= nr | [-0-9A-Za-z]+
 | 
			
		||||
```
 | 
			
		||||
 | 
			
		||||
## Functions
 | 
			
		||||
 | 
			
		||||
All methods and classes take a final `options` object argument.  All
 | 
			
		||||
options in this object are `false` by default.  The options supported
 | 
			
		||||
are:
 | 
			
		||||
 | 
			
		||||
- `loose`  Be more forgiving about not-quite-valid semver strings.
 | 
			
		||||
  (Any resulting output will always be 100% strict compliant, of
 | 
			
		||||
  course.)  For backwards compatibility reasons, if the `options`
 | 
			
		||||
  argument is a boolean value instead of an object, it is interpreted
 | 
			
		||||
  to be the `loose` param.
 | 
			
		||||
- `includePrerelease`  Set to suppress the [default
 | 
			
		||||
  behavior](https://github.com/npm/node-semver#prerelease-tags) of
 | 
			
		||||
  excluding prerelease tagged versions from ranges unless they are
 | 
			
		||||
  explicitly opted into.
 | 
			
		||||
 | 
			
		||||
Strict-mode Comparators and Ranges will be strict about the SemVer
 | 
			
		||||
strings that they parse.
 | 
			
		||||
 | 
			
		||||
* `valid(v)`: Return the parsed version, or null if it's not valid.
 | 
			
		||||
* `inc(v, release)`: Return the version incremented by the release
 | 
			
		||||
  type (`major`,   `premajor`, `minor`, `preminor`, `patch`,
 | 
			
		||||
  `prepatch`, or `prerelease`), or null if it's not valid
 | 
			
		||||
  * `premajor` in one call will bump the version up to the next major
 | 
			
		||||
    version and down to a prerelease of that major version.
 | 
			
		||||
    `preminor`, and `prepatch` work the same way.
 | 
			
		||||
  * If called from a non-prerelease version, the `prerelease` will work the
 | 
			
		||||
    same as `prepatch`. It increments the patch version, then makes a
 | 
			
		||||
    prerelease. If the input version is already a prerelease it simply
 | 
			
		||||
    increments it.
 | 
			
		||||
* `prerelease(v)`: Returns an array of prerelease components, or null
 | 
			
		||||
  if none exist. Example: `prerelease('1.2.3-alpha.1') -> ['alpha', 1]`
 | 
			
		||||
* `major(v)`: Return the major version number.
 | 
			
		||||
* `minor(v)`: Return the minor version number.
 | 
			
		||||
* `patch(v)`: Return the patch version number.
 | 
			
		||||
* `intersects(r1, r2, loose)`: Return true if the two supplied ranges
 | 
			
		||||
  or comparators intersect.
 | 
			
		||||
 | 
			
		||||
### Comparison
 | 
			
		||||
 | 
			
		||||
* `gt(v1, v2)`: `v1 > v2`
 | 
			
		||||
* `gte(v1, v2)`: `v1 >= v2`
 | 
			
		||||
* `lt(v1, v2)`: `v1 < v2`
 | 
			
		||||
* `lte(v1, v2)`: `v1 <= v2`
 | 
			
		||||
* `eq(v1, v2)`: `v1 == v2` This is true if they're logically equivalent,
 | 
			
		||||
  even if they're not the exact same string.  You already know how to
 | 
			
		||||
  compare strings.
 | 
			
		||||
* `neq(v1, v2)`: `v1 != v2` The opposite of `eq`.
 | 
			
		||||
* `cmp(v1, comparator, v2)`: Pass in a comparison string, and it'll call
 | 
			
		||||
  the corresponding function above.  `"==="` and `"!=="` do simple
 | 
			
		||||
  string comparison, but are included for completeness.  Throws if an
 | 
			
		||||
  invalid comparison string is provided.
 | 
			
		||||
* `compare(v1, v2)`: Return `0` if `v1 == v2`, or `1` if `v1` is greater, or `-1` if
 | 
			
		||||
  `v2` is greater.  Sorts in ascending order if passed to `Array.sort()`.
 | 
			
		||||
* `rcompare(v1, v2)`: The reverse of compare.  Sorts an array of versions
 | 
			
		||||
  in descending order when passed to `Array.sort()`.
 | 
			
		||||
* `diff(v1, v2)`: Returns difference between two versions by the release type
 | 
			
		||||
  (`major`, `premajor`, `minor`, `preminor`, `patch`, `prepatch`, or `prerelease`),
 | 
			
		||||
  or null if the versions are the same.
 | 
			
		||||
 | 
			
		||||
### Comparators
 | 
			
		||||
 | 
			
		||||
* `intersects(comparator)`: Return true if the comparators intersect
 | 
			
		||||
 | 
			
		||||
### Ranges
 | 
			
		||||
 | 
			
		||||
* `validRange(range)`: Return the valid range or null if it's not valid
 | 
			
		||||
* `satisfies(version, range)`: Return true if the version satisfies the
 | 
			
		||||
  range.
 | 
			
		||||
* `maxSatisfying(versions, range)`: Return the highest version in the list
 | 
			
		||||
  that satisfies the range, or `null` if none of them do.
 | 
			
		||||
* `minSatisfying(versions, range)`: Return the lowest version in the list
 | 
			
		||||
  that satisfies the range, or `null` if none of them do.
 | 
			
		||||
* `gtr(version, range)`: Return `true` if version is greater than all the
 | 
			
		||||
  versions possible in the range.
 | 
			
		||||
* `ltr(version, range)`: Return `true` if version is less than all the
 | 
			
		||||
  versions possible in the range.
 | 
			
		||||
* `outside(version, range, hilo)`: Return true if the version is outside
 | 
			
		||||
  the bounds of the range in either the high or low direction.  The
 | 
			
		||||
  `hilo` argument must be either the string `'>'` or `'<'`.  (This is
 | 
			
		||||
  the function called by `gtr` and `ltr`.)
 | 
			
		||||
* `intersects(range)`: Return true if any of the ranges comparators intersect
 | 
			
		||||
 | 
			
		||||
Note that, since ranges may be non-contiguous, a version might not be
 | 
			
		||||
greater than a range, less than a range, *or* satisfy a range!  For
 | 
			
		||||
example, the range `1.2 <1.2.9 || >2.0.0` would have a hole from `1.2.9`
 | 
			
		||||
until `2.0.0`, so the version `1.2.10` would not be greater than the
 | 
			
		||||
range (because `2.0.1` satisfies, which is higher), nor less than the
 | 
			
		||||
range (since `1.2.8` satisfies, which is lower), and it also does not
 | 
			
		||||
satisfy the range.
 | 
			
		||||
 | 
			
		||||
If you want to know if a version satisfies or does not satisfy a
 | 
			
		||||
range, use the `satisfies(version, range)` function.
 | 
			
		||||
 | 
			
		||||
### Coercion
 | 
			
		||||
 | 
			
		||||
* `coerce(version)`: Coerces a string to semver if possible
 | 
			
		||||
 | 
			
		||||
This aims to provide a very forgiving translation of a non-semver
 | 
			
		||||
string to semver. It looks for the first digit in a string, and
 | 
			
		||||
consumes all remaining characters which satisfy at least a partial semver
 | 
			
		||||
(e.g., `1`, `1.2`, `1.2.3`) up to the max permitted length (256 characters).
 | 
			
		||||
Longer versions are simply truncated (`4.6.3.9.2-alpha2` becomes `4.6.3`).
 | 
			
		||||
All surrounding text is simply ignored (`v3.4 replaces v3.3.1` becomes `3.4.0`).
 | 
			
		||||
Only text which lacks digits will fail coercion (`version one` is not valid).
 | 
			
		||||
The maximum  length for any semver component considered for coercion is 16 characters;
 | 
			
		||||
longer components will be ignored (`10000000000000000.4.7.4` becomes `4.7.4`).
 | 
			
		||||
The maximum value for any semver component is `Integer.MAX_SAFE_INTEGER || (2**53 - 1)`;
 | 
			
		||||
higher value components are invalid (`9999999999999999.4.7.4` is likely invalid).
