/** * @class Ext.Version * * A utility class that wraps around a version number string and provides convenient methods * to perform comparisons. A version number is expressed in the following general format: * * major[.minor[.patch[.build[release]]]] * * The `Version` instance holds various readonly properties that contain the digested form * of the version string. The numeric componnets of `major`, `minor`, `patch` and `build` * as well as the textual suffix called `release`. * * Not depicted in the above syntax are three possible prefixes used to control partial * matching. These are '^' (the default), '>' and '~'. These are discussed below. * * Examples: * * var version = new Ext.Version('1.0.2beta'); // or maybe "1.0" or "1.2.3.4RC" * console.log("Version is " + version); // Version is 1.0.2beta * * console.log(version.getMajor()); // 1 * console.log(version.getMinor()); // 0 * console.log(version.getPatch()); // 2 * console.log(version.getBuild()); // 0 * console.log(version.getRelease()); // beta * * The understood values of `release` are assigned numberic equivalents for the sake of * comparsion. The order of these from smallest to largest is as follows: * * * `"dev"` * * `"alpha"` or `"a"` * * `"beta"` or `"b"` * * `"RC"` or `"rc"` * * `"#"` * * `"pl"` or `"p"` * * Any other (unrecognized) suffix is consider greater than any of these. * * ## Comparisons * There are two forms of comparison that are commonly needed: full and partial. Full * comparison is simpler and is also the default. * * Example: * * var version = new Ext.Version('1.0.2beta'); * * console.log(version.isGreaterThan('1.0.1')); // True * console.log(version.isGreaterThan('1.0.2alpha')); // True * console.log(version.isGreaterThan('1.0.2RC')); // False * console.log(version.isGreaterThan('1.0.2')); // False * console.log(version.isLessThan('1.0.2')); // True * * console.log(version.match(1.0)); // True (using a Number) * console.log(version.match('1.0.2')); // True (using a String) * * These comparisons are ultimately implemented by {@link Ext.Version#compareTo compareTo} * which returns -1, 0 or 1 depending on whether the `Version' instance is less than, equal * to, or greater than the given "other" version. * * For example: * * var n = version.compareTo('1.0.1'); // == 1 (because 1.0.2beta > 1.0.1) * * n = version.compareTo('1.1'); // == -1 * n = version.compareTo(version); // == 0 * * ### Partial Comparisons * By default, unspecified version number fields are filled with 0. In other words, the * version number fields are 0-padded on the right or a "lower bound". This produces the * most commonly used forms of comparsion: * * var ver = new Version('4.2'); * * n = ver.compareTo('4.2.1'); // == -1 (4.2 promotes to 4.2.0 and is less than 4.2.1) * * There are two other ways to interpret comparisons of versions of different length. The * first of these is to change the padding on the right to be a large number (scuh as * Infinity) instead of 0. This has the effect of making the version an upper bound. For * example: * * var ver = new Version('^4.2'); // NOTE: the '^' prefix used * * n = ver.compareTo('4.3'); // == -1 (less than 4.3) * * n = ver.compareTo('4.2'); // == 1 (greater than all 4.2's) * n = ver.compareTo('4.2.1'); // == 1 * n = ver.compareTo('4.2.9'); // == 1 * * The second way to interpret this comparison is to ignore the extra digits, making the * match a prefix match. For example: * * var ver = new Version('~4.2'); // NOTE: the '~' prefix used * * n = ver.compareTo('4.3'); // == -1 * * n = ver.compareTo('4.2'); // == 0 * n = ver.compareTo('4.2.1'); // == 0 * * This final form can be useful when version numbers contain more components than are * important for certain comparisons. For example, the full version of Ext JS 4.2.1 is * "4.2.1.883" where 883 is the `build` number. * * This is how to create a "partial" `Version` and compare versions to it: * * var version421ish = new Version('~4.2.1'); * * n = version421ish.compareTo('4.2.1.883'); // == 0 * n = version421ish.compareTo('4.2.1.2'); // == 0 * n = version421ish.compareTo('4.2.1'); // == 0 * * n = version421ish.compareTo('4.2'); // == 1 * * In the above example, '4.2.1.2' compares as equal to '4.2.1' because digits beyond the * given "4.2.1" are ignored. However, '4.2' is less than the '4.2.1' prefix; its missing * digit is filled with 0. */(function() {// @define Ext.Version// @require Ext.String var // used by checkVersion to avoid temp arrays: checkVerTemp = [''], endOfVersionRe = /([^\d\.])/, notDigitsRe = /[^\d]/g, plusMinusRe = /[\-+]/g, stripRe = /\s/g, underscoreRe = /_/g, toolkitNames = { classic: 1, modern: 1}, Version; Ext.Version = Version = function(version, defaultMode) { var me = this, padModes = me.padModes, ch, i, pad, parts, release, releaseStartIndex, ver; if (version.isVersion) { version = version.version; } me.version = ver = String(version).toLowerCase(). replace(underscoreRe, '.').replace(plusMinusRe, ''); ch = ver.charAt(0); if (ch in padModes) { ver = ver.substring(1); pad = padModes[ch]; } else { pad = defaultMode ? padModes[defaultMode] : 0; // careful - NaN is falsey! } me.pad = pad; releaseStartIndex = ver.search(endOfVersionRe); me.shortVersion = ver; if (releaseStartIndex !== -1) { me.release = release = ver.substr(releaseStartIndex, version.length); me.shortVersion = ver.substr(0, releaseStartIndex); release = Version.releaseValueMap[release] || release; } me.releaseValue = release || pad; me.shortVersion = me.shortVersion.replace(notDigitsRe, ''); /** * @property {Number[]} parts * The split array of version number components found in the version string. * For example, for "1.2.3", this would be `[1, 2, 3]`. * @readonly * @private */ me.parts = parts = ver.split('.'); for (i = parts.length; i--; ) { parts[i] = parseInt(parts[i], 10); } if (pad === Infinity) { // have to add this to the end to create an upper bound: parts.push(pad); } /** * @property {Number} major * The first numeric part of the version number string. * @readonly */ me.major = parts[0] || pad; /** * @property {Number} [minor] * The second numeric part of the version number string. * @readonly */ me.minor = parts[1] || pad; /** * @property {Number} [patch] * The third numeric part of the version number string. * @readonly */ me.patch = parts[2] || pad; /** * @property {Number} [build] * The fourth numeric part of the version number string. * @readonly */ me.build = parts[3] || pad; return me; }; Version.prototype = { isVersion: true, padModes: { '~': NaN, '^': Infinity }, /** * @property {String} [release=""] * The release level.

A `spec` is either a string or an object indicating a boolean operator. * This method accepts either form or an array of these as the first argument. The * second argument applies only when the first is an array and indicates whether * all `specs` must match or just one. * * ## Package Version Specifications * The string form of a `spec` is used to indicate a version or range of versions * for a particular package. This form of `spec` consists of three (3) parts: * * * Package name followed by "@". If not provided, the framework is assumed. * * Minimum version. * * Maximum version. * * At least one version number must be provided. If both minimum and maximum are * provided, these must be separated by a "-". * * Some examples of package version specifications: * * 4.2.2 (exactly version 4.2.2 of the framework) * 4.2.2+ (version 4.2.2 or higher of the framework) * 4.2.2- (version 4.2.2 or higher of the framework) * 4.2.1 - 4.2.3 (versions from 4.2.1 up to 4.2.3 of the framework) * - 4.2.2 (any version up to version 4.2.1 of the framework) * * foo@1.0 (exactly version 1.0 of package "foo") * foo@1.0-1.3 (versions 1.0 up to 1.3 of package "foo") * * **NOTE:** This syntax is the same as that used in Sencha Cmd's package * requirements declarations. * * ## Boolean Operator Specifications * Instead of a string, an object can be used to describe a boolean operation to * perform on one or more `specs`. The operator is either **`and`** or **`or`** * and can contain an optional **`not`**. * * For example: * * { * not: true, // negates boolean result * and: [ * '4.2.2', * 'foo@1.0.1 - 2.0.1' * ] * } * * Each element of the array can in turn be a string or object spec. In other * words, the value is passed to this method (recursively) as the first argument * so these two calls are equivalent: * * Ext.checkVersion({ * not: true, // negates boolean result * and: [ * '4.2.2', * 'foo@1.0.1 - 2.0.1' * ] * }); * * !Ext.checkVersion([ * '4.2.2', * 'foo@1.0.1 - 2.0.1' * ], true); * * ## Examples * * // A specific framework version * Ext.checkVersion('4.2.2'); * * // A range of framework versions: * Ext.checkVersion('4.2.1-4.2.3'); * * // A specific version of a package: * Ext.checkVersion('foo@1.0.1'); * * // A single spec that requires both a framework version and package * // version range to match: * Ext.checkVersion({ * and: [ * '4.2.2', * 'foo@1.0.1-1.0.2' * ] * }); * * // These checks can be nested: * Ext.checkVersion({ * and: [ * '4.2.2', // exactly version 4.2.2 of the framework *AND* * { * // either (or both) of these package specs: * or: [ * 'foo@1.0.1-1.0.2', * 'bar@3.0+' * ] * } * ] * }); * * ## Version Comparisons * Version comparsions are assumed to be "prefix" based. That is to say, `"foo@1.2"` * matches any version of "foo" that has a major version 1 and a minor version of 2. * * This also applies to ranges. For example `"foo@1.2-2.2"` matches all versions * of "foo" from 1.2 up to 2.2 regardless of the specific patch and build. * * ## Use in Overrides * This methods primary use is in support of conditional overrides on an * `Ext.define` declaration. * * @param {String/Array/Object} specs A version specification string, an object * containing `or` or `and` with a value that is equivalent to `specs` or an array * of either of these. * @param {Boolean} [matchAll=false] Pass `true` to require all specs to match. * @return {Boolean} True if `specs` matches the registered package versions. */ checkVersion: function (specs, matchAll) { var isArray = Ext.isArray(specs), aliases = Version.aliases.from, compat = isArray ? specs : checkVerTemp, length = compat.length, versions = Ext.versions, frameworkVer = versions.ext || versions.touch, i, index, matches, minVer, maxVer, packageName, spec, range, ver; if (!isArray) { checkVerTemp[0] = specs; } for (i = 0; i < length; ++i) { if (!Ext.isString(spec = compat[i])) { matches = Ext.checkVersion(spec.and || spec.or, !spec.or); if (spec.not) { matches = !matches; } } else { if (spec.indexOf(' ') >= 0) { spec = spec.replace(stripRe, ''); } // For "name@..." syntax, we need to find the package by the given name // as a registered package. index = spec.indexOf('@'); if (index < 0) { range = spec; ver = frameworkVer; } else { packageName = spec.substring(0, index); if (!(ver = versions[aliases[packageName] || packageName])) { // The package is not registered, so if we must matchAll then // we are done - FAIL: if (matchAll) { return false; } // Otherwise this spec is not a match so we can move on to the // next... continue; } range = spec.substring(index+1); } // Now look for a version, version range or partial range: index = range.indexOf('-'); if (index < 0) { // just a version or "1.0+" if (range.charAt(index = range.length - 1) === '+') { minVer = range.substring(0, index); maxVer = null; } else { minVer = maxVer = range; } } else if (index > 0) { // a range like "1.0-1.5" or "1.0-" minVer = range.substring(0, index); maxVer = range.substring(index+1); // may be empty } else { // an upper limit like "-1.5" minVer = null; maxVer = range.substring(index+1); } matches = true; if (minVer) { minVer = new Version(minVer, '~'); // prefix matching matches = minVer.ltEq(ver); } if (matches && maxVer) { maxVer = new Version(maxVer, '~'); // prefix matching matches = maxVer.gtEq(ver); } } // string spec if (matches) { // spec matched and we are looking for any match, so we are GO! if (!matchAll) { return true; } } else if (matchAll) { // spec does not match the registered package version return false; } } // In the loop above, for matchAll we return FALSE on mismatch, so getting // here with matchAll means we had no mismatches.
