That's what an LRU cache is. + +For full description of the API and all options, please see [the +LRUCache typedocs](https://isaacs.github.io/node-lru-cache/) + +## Storage Bounds Safety + +This implementation aims to be as flexible as possible, within +the limits of safe memory consumption and optimal performance. + +At initial object creation, storage is allocated for `max` items. +If `max` is set to zero, then some performance is lost, and item +count is unbounded. Either `maxSize` or `ttl` _must_ be set if +`max` is not specified. + +If `maxSize` is set, then this creates a safe limit on the +maximum storage consumed, but without the performance benefits of +pre-allocation. When `maxSize` is set, every item _must_ provide +a size, either via the `sizeCalculation` method provided to the +constructor, or via a `size` or `sizeCalculation` option provided +to `cache.set()`. The size of every item _must_ be a positive +integer. + +If neither `max` nor `maxSize` are set, then `ttl` tracking must +be enabled. Note that, even when tracking item `ttl`, items are +_not_ preemptively deleted when they become stale, unless +`ttlAutopurge` is enabled. Instead, they are only purged the +next time the key is requested. Thus, if `ttlAutopurge`, `max`, +and `maxSize` are all not set, then the cache will potentially +grow unbounded. + +In this case, a warning is printed to standard error. Future +versions may require the use of `ttlAutopurge` if `max` and +`maxSize` are not specified. + +If you truly wish to use a cache that is bound _only_ by TTL +expiration, consider using a `Map` object, and calling +`setTimeout` to delete entries when they expire. It will perform +much better than an LRU cache. + +Here is an implementation you may use, under the same +[license](./LICENSE) as this package: + +```js +// a storage-unbounded ttl cache that is not an lru-cache +const cache = { + data: new Map(), + timers: new Map(), + set: (k, v, ttl) => { + if (cache.timers.has(k)) { + clearTimeout(cache.timers.get(k)) + } + cache.timers.set( + k, + setTimeout(() => cache.delete(k), ttl), + ) + cache.data.set(k, v) + }, + get: k => cache.data.get(k), + has: k => cache.data.has(k), + delete: k => { + if (cache.timers.has(k)) { + clearTimeout(cache.timers.get(k)) + } + cache.timers.delete(k) + return cache.data.delete(k) + }, + clear: () => { + cache.data.clear() + for (const v of cache.timers.values()) { + clearTimeout(v) + } + cache.timers.clear() + }, +} +``` + +If that isn't to your liking, check out +[@isaacs/ttlcache](http://npm.im/@isaacs/ttlcache). + +## Storing Undefined Values + +This cache never stores undefined values, as `undefined` is used +internally in a few places to indicate that a key is not in the +cache. + +You may call `cache.set(key, undefined)`, but this is just +an alias for `cache.delete(key)`. Note that this has the effect +that `cache.has(key)` will return _false_ after setting it to +undefined. + +```js +cache.set(myKey, undefined) +cache.has(myKey) // false! +``` + +If you need to track `undefined` values, and still note that the +key is in the cache, an easy workaround is to use a sigil object +of your own. + +```js +import { LRUCache } from 'lru-cache' +const undefinedValue = Symbol('undefined') +const cache = new LRUCache(...) +const mySet = (key, value) => + cache.set(key, value === undefined ? undefinedValue : value) +const myGet = (key, value) => { + const v = cache.get(key) + return v === undefinedValue ? undefined : v +} +``` + +## Performance + +As of January 2022, version 7 of this library is one of the most +performant LRU cache implementations in JavaScript. + +Benchmarks can be extremely difficult to get right. In +particular, the performance of set/get/delete operations on +objects will vary _wildly_ depending on the type of key used. V8 +is highly optimized for objects with keys that are short strings, +especially integer numeric strings. Thus any benchmark which +tests _solely_ using numbers as keys will tend to find that an +object-based approach performs the best. + +Note that coercing _anything_ to strings to use as object keys is +unsafe, unless you can be 100% certain that no other type of +value will be used. For example: + +```js +const myCache = {} +const set = (k, v) => (myCache[k] = v) +const get = k => myCache[k] + +set({}, 'please hang onto this for me') +set('[object Object]', 'oopsie') +``` + +Also beware of "Just So" stories regarding performance. Garbage +collection of large (especially: deep) object graphs can be +incredibly costly, with several "tipping points" where it +increases exponentially. As a result, putting that off until +later can make it much worse, and less predictable. If a library +performs well, but only in a scenario where the object graph is +kept shallow, then that won't help you if you are using large +objects as keys. + +In general, when attempting to use a library to improve +performance (such as a cache like this one), it's best to choose +an option that will perform well in the sorts of scenarios where +you'll actually use it. + +This library is optimized for repeated gets and minimizing +eviction time, since that is the expected need of a LRU. Set +operations are somewhat slower on average than a few other +options, in part because of that optimization. It is assumed +that you'll be caching some costly operation, ideally as rarely +as possible, so optimizing set over get would be unwise. + +If performance matters to you: + +1. If it's at all possible to use small integer values as keys, + and you can guarantee that no other types of values will be + used as keys, then do that, and use a cache such as + [lru-fast](https://npmjs.com/package/lru-fast), or + [mnemonist's + LRUCache](https://yomguithereal.github.io/mnemonist/lru-cache) + which uses an Object as its data store. + +2. Failing that, if at all possible, use short non-numeric + strings (ie, less than 256 characters) as your keys, and use + [mnemonist's + LRUCache](https://yomguithereal.github.io/mnemonist/lru-cache). + +3. If the types of your keys will be anything else, especially + long strings, strings that look like floats, objects, or some + mix of types, or if you aren't sure, then this library will + work well for you. + + If you do not need the features that this library provides + (like asynchronous fetching, a variety of TTL staleness + options, and so on), then [mnemonist's + LRUMap](https://yomguithereal.github.io/mnemonist/lru-map) is + a very good option, and just slightly faster than this module + (since it does considerably less). + +4. Do not use a `dispose` function, size tracking, or especially + ttl behavior, unless absolutely needed. These features are + convenient, and necessary in some use cases, and every attempt + has been made to make the performance impact minimal, but it + isn't nothing. + +## Breaking Changes in Version 7 + +This library changed to a different algorithm and internal data +structure in version 7, yielding significantly better +performance, albeit with some subtle changes as a result. + +If you were relying on the internals of LRUCache in version 6 or +before, it probably will not work in version 7 and above. + +## Breaking Changes in Version 8 + +- The `fetchContext` option was renamed to `context`, and may no + longer be set on the cache instance itself. +- Rewritten in TypeScript, so pretty much all the types moved + around a lot. +- The AbortController/AbortSignal polyfill was removed. For this + reason, **Node version 16.14.0 or higher is now required**. +- Internal properties were moved to actual private class + properties. +- Keys and values must not be `null` or `undefined`. +- Minified export available at `'lru-cache/min'`, for both CJS + and MJS builds. + +## Breaking Changes in Version 9 + +- Named export only, no default export. +- AbortController polyfill returned, albeit with a warning when + used. + +## Breaking Changes in Version 10 + +- `cache.fetch()` return type is now `Promise` + instead of `Promise`. This is an irrelevant change + practically speaking, but can require changes for TypeScript + users. + +For more info, see the [change log](CHANGELOG.md). diff --git a/node_modules/@asamuzakjp/css-color/node_modules/lru-cache/package.json b/node_modules/@asamuzakjp/css-color/node_modules/lru-cache/package.json new file mode 100644 index 00000000..24bb077d --- /dev/null +++ b/node_modules/@asamuzakjp/css-color/node_modules/lru-cache/package.json @@ -0,0 +1,113 @@ +{ + "name": "lru-cache", + "description": "A cache object that deletes the least-recently-used items.", + "version": "11.2.2", + "author": "Isaac Z.

That's what an LRU cache is. + +For full description of the API and all options, please see [the +LRUCache typedocs](https://isaacs.github.io/node-lru-cache/) + +## Storage Bounds Safety + +This implementation aims to be as flexible as possible, within +the limits of safe memory consumption and optimal performance. + +At initial object creation, storage is allocated for `max` items. +If `max` is set to zero, then some performance is lost, and item +count is unbounded. Either `maxSize` or `ttl` _must_ be set if +`max` is not specified. + +If `maxSize` is set, then this creates a safe limit on the +maximum storage consumed, but without the performance benefits of +pre-allocation. When `maxSize` is set, every item _must_ provide +a size, either via the `sizeCalculation` method provided to the +constructor, or via a `size` or `sizeCalculation` option provided +to `cache.set()`. The size of every item _must_ be a positive +integer. + +If neither `max` nor `maxSize` are set, then `ttl` tracking must +be enabled. Note that, even when tracking item `ttl`, items are +_not_ preemptively deleted when they become stale, unless +`ttlAutopurge` is enabled. Instead, they are only purged the +next time the key is requested. Thus, if `ttlAutopurge`, `max`, +and `maxSize` are all not set, then the cache will potentially +grow unbounded. + +In this case, a warning is printed to standard error. Future +versions may require the use of `ttlAutopurge` if `max` and +`maxSize` are not specified. + +If you truly wish to use a cache that is bound _only_ by TTL +expiration, consider using a `Map` object, and calling +`setTimeout` to delete entries when they expire. It will perform +much better than an LRU cache. + +Here is an implementation you may use, under the same +[license](./LICENSE) as this package: + +```js +// a storage-unbounded ttl cache that is not an lru-cache +const cache = { + data: new Map(), + timers: new Map(), + set: (k, v, ttl) => { + if (cache.timers.has(k)) { + clearTimeout(cache.timers.get(k)) + } + cache.timers.set( + k, + setTimeout(() => cache.delete(k), ttl), + ) + cache.data.set(k, v) + }, + get: k => cache.data.get(k), + has: k => cache.data.has(k), + delete: k => { + if (cache.timers.has(k)) { + clearTimeout(cache.timers.get(k)) + } + cache.timers.delete(k) + return cache.data.delete(k) + }, + clear: () => { + cache.data.clear() + for (const v of cache.timers.values()) { + clearTimeout(v) + } + cache.timers.clear() + }, +} +``` + +If that isn't to your liking, check out +[@isaacs/ttlcache](http://npm.im/@isaacs/ttlcache). + +## Storing Undefined Values + +This cache never stores undefined values, as `undefined` is used +internally in a few places to indicate that a key is not in the +cache. + +You may call `cache.set(key, undefined)`, but this is just +an alias for `cache.delete(key)`. Note that this has the effect +that `cache.has(key)` will return _false_ after setting it to +undefined. + +```js +cache.set(myKey, undefined) +cache.has(myKey) // false! +``` + +If you need to track `undefined` values, and still note that the +key is in the cache, an easy workaround is to use a sigil object +of your own. + +```js +import { LRUCache } from 'lru-cache' +const undefinedValue = Symbol('undefined') +const cache = new LRUCache(...) +const mySet = (key, value) => + cache.set(key, value === undefined ? undefinedValue : value) +const myGet = (key, value) => { + const v = cache.get(key) + return v === undefinedValue ? undefined : v +} +``` + +## Performance + +As of January 2022, version 7 of this library is one of the most +performant LRU cache implementations in JavaScript. + +Benchmarks can be extremely difficult to get right. In +particular, the performance of set/get/delete operations on +objects will vary _wildly_ depending on the type of key used. V8 +is highly optimized for objects with keys that are short strings, +especially integer numeric strings. Thus any benchmark which +tests _solely_ using numbers as keys will tend to find that an +object-based approach performs the best. + +Note that coercing _anything_ to strings to use as object keys is +unsafe, unless you can be 100% certain that no other type of +value will be used. For example: + +```js +const myCache = {} +const set = (k, v) => (myCache[k] = v) +const get = k => myCache[k] + +set({}, 'please hang onto this for me') +set('[object Object]', 'oopsie') +``` + +Also beware of "Just So" stories regarding performance. Garbage +collection of large (especially: deep) object graphs can be +incredibly costly, with several "tipping points" where it +increases exponentially. As a result, putting that off until +later can make it much worse, and less predictable. If a library +performs well, but only in a scenario where the object graph is +kept shallow, then that won't help you if you are using large +objects as keys. + +In general, when attempting to use a library to improve +performance (such as a cache like this one), it's best to choose +an option that will perform well in the sorts of scenarios where +you'll actually use it. + +This library is optimized for repeated gets and minimizing +eviction time, since that is the expected need of a LRU. Set +operations are somewhat slower on average than a few other +options, in part because of that optimization. It is assumed +that you'll be caching some costly operation, ideally as rarely +as possible, so optimizing set over get would be unwise. + +If performance matters to you: + +1. If it's at all possible to use small integer values as keys, + and you can guarantee that no other types of values will be + used as keys, then do that, and use a cache such as + [lru-fast](https://npmjs.com/package/lru-fast), or + [mnemonist's + LRUCache](https://yomguithereal.github.io/mnemonist/lru-cache) + which uses an Object as its data store. + +2. Failing that, if at all possible, use short non-numeric + strings (ie, less than 256 characters) as your keys, and use + [mnemonist's + LRUCache](https://yomguithereal.github.io/mnemonist/lru-cache). + +3. If the types of your keys will be anything else, especially + long strings, strings that look like floats, objects, or some + mix of types, or if you aren't sure, then this library will + work well for you. + + If you do not need the features that this library provides + (like asynchronous fetching, a variety of TTL staleness + options, and so on), then [mnemonist's + LRUMap](https://yomguithereal.github.io/mnemonist/lru-map) is + a very good option, and just slightly faster than this module + (since it does considerably less). + +4. Do not use a `dispose` function, size tracking, or especially + ttl behavior, unless absolutely needed. These features are + convenient, and necessary in some use cases, and every attempt + has been made to make the performance impact minimal, but it + isn't nothing. + +## Breaking Changes in Version 7 + +This library changed to a different algorithm and internal data +structure in version 7, yielding significantly better +performance, albeit with some subtle changes as a result. + +If you were relying on the internals of LRUCache in version 6 or +before, it probably will not work in version 7 and above. + +## Breaking Changes in Version 8 + +- The `fetchContext` option was renamed to `context`, and may no + longer be set on the cache instance itself. +- Rewritten in TypeScript, so pretty much all the types moved + around a lot. +- The AbortController/AbortSignal polyfill was removed. For this + reason, **Node version 16.14.0 or higher is now required**. +- Internal properties were moved to actual private class + properties. +- Keys and values must not be `null` or `undefined`. +- Minified export available at `'lru-cache/min'`, for both CJS + and MJS builds. + +## Breaking Changes in Version 9 + +- Named export only, no default export. +- AbortController polyfill returned, albeit with a warning when + used. + +## Breaking Changes in Version 10 + +- `cache.fetch()` return type is now `Promise` + instead of `Promise`. This is an irrelevant change + practically speaking, but can require changes for TypeScript + users. + +For more info, see the [change log](CHANGELOG.md). diff --git a/node_modules/@asamuzakjp/dom-selector/node_modules/lru-cache/package.json b/node_modules/@asamuzakjp/dom-selector/node_modules/lru-cache/package.json new file mode 100644 index 00000000..24bb077d --- /dev/null +++ b/node_modules/@asamuzakjp/dom-selector/node_modules/lru-cache/package.json @@ -0,0 +1,113 @@ +{ + "name": "lru-cache", + "description": "A cache object that deletes the least-recently-used items.", + "version": "11.2.2", + "author": "Isaac Z.

This enables that function to be stringified and passed into a web worker, for example.) + +Now that you have the `bidi` object, you can: + +### Calculate bidi embedding levels + +```js +const embeddingLevels = bidi.getEmbeddingLevels( + text, //the input string containing mixed-direction text + explicitDirection //"ltr" or "rtl" if you don't want to auto-detect it +) + +const { levels, paragraphs } = embeddingLevels +``` + +The result object `embeddingLevels` will usually be passed to other functions described below. Its contents, should you need to inspect them individually, are: + +* `levels` is a `Uint8Array` holding the calculated [bidi embedding levels](https://unicode.org/reports/tr9/#BD2) for each character in the string. The most important thing to know about these levels is that any given character is in a right-to-left scope if its embedding level is an odd number, and left-to-right if it's an even number. + +* `paragraphs` is an array of `{start, end, level}` objects, one for each paragraph in the text (paragraphs are separated by explicit breaking characters, not soft line wrapping). The `start` and `end` indices are inclusive, and `level` is the resolved base embedding level of that paragraph. + +### Calculate character reorderings + +```js +const flips = bidi.getReorderSegments( + text, //the full input string + embeddingLevels //the full result object from getEmbeddingLevels +) + +// Process all reversal sequences, in order: +flips.forEach(range => { + const [start, end] = range + // Reverse this sequence of characters from start to end, inclusive + for (let i = start; i <= end; i++) { + //... + } +}) +``` + +Each "flip" is a range that should be reversed in place; they must all be applied in order. + +Sometimes you don't want to process the whole string at once, but just a particular substring. A common example would be if you've applied line wrapping, in which case you need to process each line individually (in particular this does some special handling for trailing whitespace for each line). For this you can pass the extra `start` and `end` parameters: + +```js +yourWrappedLines.forEach(([lineStart, lineEnd]) => { + const flips = bidi.getReorderSegments( + text, + embeddingLevels, + lineStart, + lineEnd //inclusive + ) + // ...process flips for this line +}) +``` + +### Handle right-to-left mirrored characters + +Some characters that resolve to right-to-left need to be swapped with their "mirrored" characters. Examples of this are opening/closing parentheses. You can determine all the characters that need to be mirrored like so: + +```js +const mirrored = bidi.getMirroredCharactersMap( + text, + embeddingLevels +) +``` + +This returns a `Map` of numeric character indices to replacement characters. + +You can also process just a substring with extra `start` and `end` parameters: + +```js +const mirrored = bidi.getMirroredCharactersMap( + text, + embeddingLevels, + start, + end //inclusive +) +``` + +If you'd rather process mirrored characters individually, you can use the single `getMirroredCharacter` function, just make sure you only do it for right-to-left characters (those whose embedding level is an odd number.) It will return `null` if the character doesn't support mirroring. + +```js +const mirroredChar = (embeddingLevels.levels[charIndex] & 1) //odd number means RTL + ? bidi.getMirroredCharacter(text[charIndex]) + : null +``` + +### Get a character's bidi type + +This is used internally, but you can also ask for the ["bidi character type"](https://unicode.org/reports/tr9/#BD1) of any character, should you need it: + +```js +const bidiType = bidi.getBidiCharTypeName(string[charIndex]) +// e.g. "L", "R", "AL", "NSM", ... +``` diff

The main goal is to be efficient and W3C spec compliant, with focus on CSS analyzing and source-to-source transforming tasks. + +## Features + +- **Detailed parsing with an adjustable level of detail** + + By default CSSTree parses CSS as detailed as possible, i.e. each single logical part is representing with its own AST node (see [AST format](docs/ast.md) for all possible node types). The parsing detail level can be changed through [parser options](docs/parsing.md#parsesource-options), for example, you can disable parsing of selectors or declaration values for component parts. + +- **Tolerant to errors by design** + + Parser behaves as [spec says](https://www.w3.org/TR/css-syntax-3/#error-handling): "When errors occur in CSS, the parser attempts to recover gracefully, throwing away only the minimum amount of content before returning to parsing as normal". The only thing the parser departs from the specification is that it doesn't throw away bad content, but wraps it in a special node type (`Raw`) that allows processing it later. + +- **Fast and efficient** + + CSSTree is created with focus on performance and effective memory consumption. Therefore it's [one of the fastest CSS parsers](https://github.com/postcss/benchmark) at the moment. + +- **Syntax validation** + + The built-in lexer can test CSS against syntaxes defined by W3C. CSSTree uses [mdn/data](https://github.com/mdn/data/) as a basis for lexer's dictionaries and extends it with vendor specific and legacy syntaxes. Lexer can only check the declaration values and at-rules currently, but this feature will be extended to other parts of the CSS in the future. + +## Projects using CSSTree + +- [Svelte](https://github.com/sveltejs/svelte) – Cybernetically enhanced web apps +- [SVGO](https://github.com/svg/svgo) – Node.js tool for optimizing SVG files +- [CSSO](https://github.com/css/csso) – CSS minifier with structural optimizations +- [NativeScript](https://github.com/NativeScript/NativeScript) – NativeScript empowers you to access native APIs from JavaScript directly +- [react-native-svg](https://github.com/react-native-svg/react-native-svg) – SVG library for React Native, React Native Web, and plain React web projects +- [penthouse](https://github.com/pocketjoso/penthouse) – Critical Path CSS Generator +- [Bit](https://github.com/teambit/bit) – Bit is the platform for collaborating on components +- and more... + +## Documentation + +- [AST format](docs/ast.md) +- [Parsing CSS → AST](docs/parsing.md) + - [parse(source[, options])](docs/parsing.md#parsesource-options) +- [Serialization AST → CSS](docs/generate.md) + - [generate(ast[, options])](docs/generate.md#generateast-options) +- [AST traversal](docs/traversal.md) + - [walk(ast, options)](docs/traversal.md#walkast-options) + - [find(ast, fn)](docs/traversal.md#findast-fn) + - [findLast(ast, fn)](docs/traversal.md#findlastast-fn) + - [findAll(ast, fn)](docs/traversal.md#findallast-fn) +- [Util functions](docs/utils.md) + - Value encoding & decoding + - [property(name)](docs/utils.md#propertyname) + - [keyword(name)](docs/utils.md#keywordname) + - [ident](docs/utils.md#ident) + - [string](docs/utils.md#string) + - [url](docs/utils.md#url) + - [List class](docs/list.md) + - AST transforming + - [clone(ast)](docs/utils.md#cloneast) + - [fromPlainObject(object)](docs/utils.md#fromplainobjectobject) + - [toPlainObject(ast)](docs/utils.md#toplainobjectast) +- [Value Definition Syntax](docs/definition-syntax.md) + - [parse(source)](docs/definition-syntax.md#parsesource) + - [walk(node, options, context)](docs/definition-syntax.md#walknode-options-context) + - [generate(node, options)](docs/definition-syntax.md#generatenode-options) + - [AST format](docs/definition-syntax.md#ast-format) + +## Tools + +* [AST Explorer](https://astexplorer.net/#/gist/244e2fb4da940df52bf0f4b94277db44/e79aff44611020b22cfd9708f3a99ce09b7d67a8) – explore CSSTree AST format with zero setup +* [CSS syntax reference](https://csstree.github.io/docs/syntax.html) +* [CSS syntax validator](https://csstree.github.io/docs/validator.html) + +## Related projects + +* [csstree-validator](https://github.com/csstree/validator) – NPM package to validate CSS +* [stylelint-csstree-validator](https://github.com/csstree/stylelint-validator) – plugin for stylelint to validate CSS +* [Grunt plugin](https://github.com/sergejmueller/grunt-csstree-validator) +* [Gulp plugin](https://github.com/csstree/gulp-csstree) +* [Sublime plugin](https://github.com/csstree/SublimeLinter-contrib-csstree) +* [VS Code plugin](https://github.com/csstree/vscode-plugin) +* [Atom plugin](https://github.com/csstree/atom-plugin) + +## Usage + +Install with npm: + +``` +npm install css-tree +``` + +Basic usage: + +```js +import * as csstree from 'css-tree'; + +// parse CSS to AST +const ast = csstree.parse('.example { world: "!" }'); + +// traverse AST and modify it +csstree.walk(ast, (node) => { + if (node.type === 'ClassSelector' && node.name === 'example') { + node.name = 'hello'; + } +}); + +// generate CSS from AST +console.log(csstree.generate(ast)); +// .hello{world:"!"} +``` + +Syntax matching: + +```js +// parse CSS to AST as a declaration value +const ast = csstree.parse('red 1px solid', { context: 'value' }); + +// match to syntax of `border` property +const matchResult = csstree.lexer.matchProperty('border', ast); + +// check first value node is a +console.log(matchResult.isType(ast.children.first, 'color')); +// true + +// get a type list matched to a node +console.log(matchResult.getTrace(ast.children.first)); +// [ { type: 'Property', name: 'border' }, +// { type: 'Type', name: 'color' }, +// { type: 'Type', name: 'named-color' }, +// { type: 'Keyword', name: 'red' } ] +``` + +### Exports + +Is it possible to import just a needed part of library like a parser or a walker.
