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.

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. +* `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)`: 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). diff --git a/tools/node_modules/eslint/node_modules/semver/bin/semver b/tools/node_modules/eslint/node_modules/cross-spawn/node_modules/semver/bin/semver index 801e77f130..801e77f130 100755 --- a/tools/node_modules/eslint/node_modules/semver/bin/semver +++ b/tools/node_modules/eslint/node_modules/cross-spawn/node_modules/semver/bin/semver diff --git a/tools/node_modules/eslint/node_modules/cross-spawn/node_modules/semver/package.json b/tools/node_modules/eslint/node_modules/cross-spawn/node_modules/semver/package.json new file mode 100644 index 0000000000..c81acfc3af --- /dev/null +++ b/tools/node_modules/eslint/node_modules/cross-spawn/node_modules/semver/package.json @@ -0,0 +1,37 @@ +{ + "bin": { + "semver": "./bin/semver" + }, + "bugs": { + "url": "https://github.com/npm/node-semver/issues" + }, + "bundleDependencies": false, + "deprecated": false, + "description": "The semantic version parser used by npm.", + "devDependencies": { + "tap": "^13.0.0-rc.18" + }, + "files": [ + "bin", + "range.bnf", + "semver.js" + ], + "homepage": "https://github.com/npm/node-semver#readme", + "license": "ISC", + "main": "semver.js", + "name": "semver", + "repository": { + "type": "git", + "url": "git+https://github.com/npm/node-semver.git" + }, + "scripts": { + "postpublish": "git push origin --all; git push origin --tags", + "postversion": "npm publish", + "preversion": "npm test", + "test": "tap" + }, + "tap": { + "check-coverage": true + }, + "version": "5.7.0" +}

We test for both standard and non-standard codes, as most of them follow the same or similar format and can be safely matched in strings without the risk of removing actual string content. There are a few non-standard control codes that do not follow the traditional format (i.e. they end in numbers) thus forcing us to exclude them from the test because we cannot reliably match them. - -On the historical side, those ECMA standards were established in the early 90's whereas the VT100, for example, was designed in the mid/late 70's. At that point in time, control codes were still pretty ungoverned and engineers used them for a multitude of things, namely to activate hardware ports that may have been proprietary. Somewhere else you see a similar 'anarchy' of codes is in the x86 architecture for processors; there are a ton of "interrupts" that can mean different things on certain brands of processors, most of which have been phased out. - - -## Security - -To report a security vulnerability, please use the [Tidelift security contact](https://tidelift.com/security).
