# @npmcli/git
A utility for spawning git from npm CLI contexts.
This is _not_ an implementation of git itself, it's just a thing that
spawns child processes to tell the system git CLI implementation to do
stuff.
## USAGE
```js
const git = require('@npmcli/git')
git.clone('git://foo/bar.git', 'some-branch', 'some-path', opts) // clone a repo
.then(() => git.spawn(['checkout', 'some-branch'], {cwd: 'bar'}))
.then(() => git.spawn(['you get the idea']))
```
## API
Most methods take an options object. Options are described below.
### `git.spawn(args, opts = {})`
Launch a `git` subprocess with the arguments specified.
All the other functions call this one at some point.
Processes are launched using
[`@npmcli/promise-spawn`](http://npm.im/@npmcli/promise-spawn), with the
`stdioString: true` option enabled by default, since git output is
generally in readable string format.
Return value is a `Promise` that resolves to a result object with `{cmd,
args, code, signal, stdout, stderr}` members, or rejects with an error with
the same fields, passed back from
[`@npmcli/promise-spawn`](http://npm.im/@npmcli/promise-spawn).
### `git.clone(repo, ref = 'HEAD', target = null, opts = {})` -> `Promise<sha String>`
Clone the repository into `target` path (or the default path for the name
of the repository), checking out `ref`.
Return value is the sha of the current HEAD in the locally cloned
repository.
In lieu of a specific `ref`, you may also pass in a `spec` option, which is
a [`npm-package-arg`](http://npm.im/npm-package-arg) object for a `git`
package dependency reference. In this way, you can select SemVer tags
within a range, or any git committish value. For example:
```js
const npa = require('npm-package-arg')
git.clone('git@github.com:npm/git.git', '', null, {
spec: npa('github:npm/git#semver:1.x'),
})
// only gitRange and gitCommittish are relevant, so this works, too
git.clone('git@github.com:npm/git.git', null, null, {
spec: { gitRange: '1.x' }
})
```
This will automatically do a shallow `--depth=1` clone on any hosts that
are known to support it. To force a shallow or deep clone, you can set the
`gitShallow` option to `true` or `false` respectively.
### `git.revs(repo, opts = {})` -> `Promise<rev doc Object>`
Fetch a representation of all of the named references in a given
repository. The resulting doc is intentionally somewhat
[packument](https://www.npmjs.com/package/pacote#packuments)-like, so that
git semver ranges can be applied using the same
[`npm-pick-manifest`](http://npm.im/npm-pick-manifest) logic.
The resulting object looks like:
```js
revs = {
versions: {
// all semver-looking tags go in here...
// version: { sha, ref, rawRef, type }
'1.0.0': {
sha: '1bc5fba3353f8e1b56493b266bc459276ab23139',
ref: 'v1.0.0',
rawRef: 'refs/tags/v1.0.0',
type: 'tag',
},
},
'dist-tags': {
HEAD: '1.0.0',
latest: '1.0.0',
},
refs: {
// all the advertised refs that can be cloned down remotely
HEAD: { sha, ref, rawRef, type: 'head' },
master: { ... },
'v1.0.0': { ... },
'refs/tags/v1.0.0': { ... },
},
shas: {
// all named shas referenced above
// sha: [list, of, refs]
'6b2501f9183a1753027a9bf89a184b7d3d4602c7': [
'HEAD',
'master',
'refs/heads/master',
],
'1bc5fba3353f8e1b56493b266bc459276ab23139': [ 'v1.0.0', 'refs/tags/v1.0.0' ],
},
}
```
### `git.is(opts)` -> `Promise<Boolean>`
Resolve to `true` if the path argument refers to the root of a git
repository.
It does this by looking for a file in `${path}/.git/index`, which is not an
airtight indicator, but at least avoids being fooled by an empty directory
or a file named `.git`.
### `git.find(opts)` -> `Promise<String | null>`
Given a path, walk up the file system tree until a git repo working
directory is found. Since this calls `stat` a bunch of times, it's
probably best to only call it if you're reasonably sure you're likely to be
in a git project somewhere. Pass in `opts.root` to stop checking at that
directory.
Resolves to `null` if not in a git project.
### `git.isClean(opts = {})` -> `Promise<Boolean>`
Return true if in a git dir, and that git dir is free of changes. This
will resolve `true` if the git working dir is clean, or `false` if not, and
reject if the path is not within a git directory or some other error
occurs.
## OPTIONS
- `retry` An object to configure retry behavior for transient network
errors with exponential backoff.
- `retries`: Defaults to `opts.fetchRetries` or 2
- `factor`: Defaults to `opts.fetchRetryFactor` or 10
- `maxTimeout`: Defaults to `opts.fetchRetryMaxtimeout` or 60000
- `minTimeout`: Defaults to `opts.fetchRetryMintimeout` or 1000
- `git` Path to the `git` binary to use. Will look up the first `git` in
the `PATH` if not specified.
- `spec` The [`npm-package-arg`](http://npm.im/npm-package-arg) specifier
object for the thing being fetched (if relevant).
- `fakePlatform` set to a fake value of `process.platform` to use. (Just
for testing `win32` behavior on Unix, and vice versa.)
- `cwd` The current working dir for the git command. Particularly for
`find` and `is` and `isClean`, it's good to know that this defaults to
`process.cwd()`, as one might expect.
- Any other options that can be passed to
[`@npmcli/promise-spawn`](http://npm.im/@npmcli/promise-spawn), or
`child_process.spawn()`.

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.minVersion('>=1.0.0') // '1.0.0'
semver.valid(semver.coerce('v2')) // '2.0.0'
semver.valid(semver.coerce('42.6.7.9.3-alpha')) // '42.6.7'
```

you'd like to minimize your footprint.

```
$ semver -h
A JavaScript implementation of the https://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
-n <0|1>
This is the base to be used for the prerelease identifier.
-p --include-prerelease
Always include prerelease versions in range matching
-c --coerce
Coerce a string into SemVer if possible
(does not imply --loose)
--rtl
Coerce version strings right to left
--ltr
Coerce version strings left to right (default)
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
<https://semver.org/>.
A leading `"="` or `"v"` character is stripped off and ignored.
## Ranges
A `version range` is a set of `comparators` that 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`. The comparator `>1` is equivalent to `>=2.0.0` and
would match the versions `2.0.0` and `3.1.0`, but not the versions
`1.0.1` 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.
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 of 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
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.
Note that this behavior can be suppressed (treating all prerelease
versions as if they were normal versions, for range-matching)
by setting the `includePrerelease` flag on the options
object to any
[functions](https://github.com/npm/node-semver#functions) that do
range matching.
#### 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
```
#### Prerelease Identifier Base
The method `.inc` takes an optional parameter 'identifierBase' string
that will let you let your prerelease number as zero-based or one-based.
Set to `false` to omit the prerelease number altogether.
If you do not specify this parameter, it will default to zero-based.
```javascript
semver.inc('1.2.3', 'prerelease', 'beta', '1')
// '1.2.4-beta.1'
```
```javascript
semver.inc('1.2.3', 'prerelease', 'beta', false)
// '1.2.4-beta'
```
command-line example:
```bash
$ semver 1.2.3 -i prerelease --preid beta -n 1
1.2.4-beta.1
```
```bash
$ semver 1.2.3 -i prerelease --preid beta -n false
1.2.4-beta
```
### 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 <2.4.0-0`
* `1.2.3 - 2` := `>=1.2.3 <3.0.0-0`
#### 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 non-prerelease version satisfies, unless
`includePrerelease` is specified, in which case any version at all
satisfies)
* `1.x` := `>=1.0.0 <2.0.0-0` (Matching major version)
* `1.2.x` := `>=1.2.0 <1.3.0-0` (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 <2.0.0-0`
* `1.2` := `1.2.x` := `>=1.2.0 <1.3.0-0`
#### 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 <1.3.0-0`
* `~1.2` := `>=1.2.0 <1.(2+1).0` := `>=1.2.0 <1.3.0-0` (Same as `1.2.x`)
* `~1` := `>=1.0.0 <(1+1).0.0` := `>=1.0.0 <2.0.0-0` (Same as `1.x`)
* `~0.2.3` := `>=0.2.3 <0.(2+1).0` := `>=0.2.3 <0.3.0-0`
* `~0.2` := `>=0.2.0 <0.(2+1).0` := `>=0.2.0 <0.3.0-0` (Same as `0.2.x`)
* `~0` := `>=0.0.0 <(0+1).0.0` := `>=0.0.0 <1.0.0-0` (Same as `0.x`)
* `~1.2.3-beta.2` := `>=1.2.3-beta.2 <1.3.0-0` 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.
#### Caret Ranges `^1.2.3` `^0.2.5` `^0.0.4`
Allows changes that do not modify the left-most non-zero element 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`
* `^0.2.3` := `>=0.2.3 <0.3.0-0`
* `^0.0.3` := `>=0.0.3 <0.0.4-0`
* `^1.2.3-beta.2` := `>=1.2.3-beta.2 <2.0.0-0` 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 <0.0.4-0` 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`
* `^0.0.x` := `>=0.0.0 <0.1.0-0`
* `^0.0` := `>=0.0.0 <0.1.0-0`
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`
* `^0.x` := `>=0.0.0 <1.0.0-0`
### 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, options, identifier, identifierBase)`:
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, `prerelease` will work the
same as `prepatch`. It increments the patch version and then makes a
prerelease. If the input version is already a prerelease it simply
increments it.
* `identifier` can be used to prefix `premajor`, `preminor`,
`prepatch`, or `prerelease` version increments. `identifierBase`
is the base to be used for the `prerelease` identifier.
* `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.
* `parse(v)`: Attempt to parse a string as a semantic version, returning either
a `SemVer` object or `null`.
### 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 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()`.
* `compareBuild(v1, v2)`: The same as `compare` but considers `build` when two versions
are equal. Sorts in ascending order if passed to `Array.sort()`.
* `compareLoose(v1, v2)`: Short for ``compare(v1, v2, { loose: true })`.
* `diff(v1, v2)`: Returns the difference between two versions by the release type
(`major`, `premajor`, `minor`, `preminor`, `patch`, `prepatch`, or `prerelease`),
or null if the versions are the same.
### Sorting
* `sort(versions)`: Returns a sorted array of versions based on the `compareBuild`
function.
* `rsort(versions)`: The reverse of `sort`. Returns an array of versions based on
the `compareBuild` function in descending order.
### 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.
* `minVersion(range)`: Return the lowest version that can match
the given range.
* `gtr(version, range)`: Return `true` if the version is greater than all the
versions possible in the range.
* `ltr(version, range)`: Return `true` if the 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 range comparators intersect.
* `simplifyRange(versions, range)`: Return a "simplified" range that
matches the same items in the `versions` list as the range specified. Note
that it does *not* guarantee that it would match the same versions in all
cases, only for the set of versions provided. This is useful when
generating ranges by joining together multiple versions with `||`
programmatically, to provide the user with something a bit more
ergonomic. If the provided range is shorter in string-length than the
generated range, then that is returned.
* `subset(subRange, superRange)`: Return `true` if the `subRange` range is
entirely contained by the `superRange` range.
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 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, options)`: 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 `Number.MAX_SAFE_INTEGER || (2**53 - 1)`; higher value
components are invalid (`9999999999999999.4.7.4` is likely invalid).
If the `options.rtl` flag is set, then `coerce` will return the right-most
coercible tuple that does not share an ending index with a longer coercible
tuple. For example, `1.2.3.4` will return `2.3.4` in rtl mode, not
`4.0.0`. `1.2.3/4` will return `4.0.0`, because the `4` is not a part of
any other overlapping SemVer tuple.
If the `options.includePrerelease` flag is set, then the `coerce` result will contain
prerelease and build parts of a version. For example, `1.2.3.4-rc.1+rev.2`
will preserve prerelease `rc.1` and build `rev.2` in the result.
### Clean
* `clean(version)`: Clean a string to be a valid semver if possible
This will return a cleaned and trimmed semver version. If the provided
version is not valid a null will be returned. This does not work for
ranges.
ex.
* `s.clean(' = v 2.1.5foo')`: `null`
* `s.clean(' = v 2.1.5foo', { loose: true })`: `'2.1.5-foo'`
* `s.clean(' = v 2.1.5-foo')`: `null`
* `s.clean(' = v 2.1.5-foo', { loose: true })`: `'2.1.5-foo'`
* `s.clean('=v2.1.5')`: `'2.1.5'`
* `s.clean(' =v2.1.5')`: `'2.1.5'`
* `s.clean(' 2.1.5 ')`: `'2.1.5'`
* `s.clean('~1.0.0')`: `null`
## Constants
As a convenience, helper constants are exported to provide information about what `node-semver` supports:
### `RELEASE_TYPES`
- major
- premajor
- minor
- preminor
- patch
- prepatch
- prerelease
```
const semver = require('semver');
if (semver.RELEASE_TYPES.includes(arbitraryUserInput)) {
console.log('This is a valid release type!');
} else {
console.warn('This is NOT a valid release type!');
}
```
### `SEMVER_SPEC_VERSION`
2.0.0
```
const semver = require('semver');
console.log('We are currently using the semver specification version:', semver.SEMVER_SPEC_VERSION);
```

`SemVer ${version}
A JavaScript implementation of the https://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)
--rtl
Coerce version strings right to left
--ltr
Coerce version strings left to right (default)
-n <base>
Base number to be used for the prerelease identifier.
Can be either 0 or 1, or false to omit the number altogether.
Defaults to 0.
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.`)

# which
Like the unix `which` utility.
Finds the first instance of a specified executable in the PATH
environment variable. Does not cache the results, so `hash -r` is not
needed when the PATH changes.
## USAGE
```javascript
const which = require('which')
// async usage
// rejects if not found
const resolved = await which('node')
// if nothrow option is used, returns null if not found
const resolvedOrNull = await which('node', { nothrow: true })
// sync usage
// throws if not found
const resolved = which.sync('node')
// if nothrow option is used, returns null if not found
const resolvedOrNull = which.sync('node', { nothrow: true })
// Pass options to override the PATH and PATHEXT environment vars.
await which('node', { path: someOtherPath, pathExt: somePathExt })
```
## CLI USAGE
Just like the BSD `which(1)` binary but using `node-which`.
```
usage: node-which [-as] program ...
```
You can learn more about why the binary is `node-which` and not `which`
[here](https://github.com/npm/node-which/pull/67)
## OPTIONS
You may pass an options object as the second argument.
- `path`: Use instead of the `PATH` environment variable.
- `pathExt`: Use instead of the `PATHEXT` environment variable.
- `all`: Return all matches, instead of just the first one. Note that
this means the function returns an array of strings instead of a
single string.
