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. + +Note that this behavior can be suppressed (treating all prerelease +versions as if they were normal versions, for the purpose of 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 +``` + +### 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.

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` +* `^0.2.3` := `>=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`.

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. +* `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 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()`. +* `compareBuild(v1, v2)`: The same as `compare` but considers `build` when two versions + are equal. Sorts in ascending order if passed to `Array.sort()`. + `v2` is greater. Sorts in ascending order if 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. +* `minVersion(range)`: Return the lowest version that can possibly match + the given range. +* `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, 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. + +### 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.
