Don't just get your website up and done, as -you'll need skills with these tools throughout the rest of the course. - -Assignment details ---- - -This assignment requires that your website is both contained in a GitHub repository and hosted in Glitch. There are two ways to do this: - -1. Fork this repo and clone it to your computer, make changes locally on your computer, push the repo onto GitHub, and then import your GitHub repo into Glitch. -2. Fork this repo and then import it directly to Glitch, use the Glitch editor to make changes, and then export your repo from Glitch back to GitHub. -3. Same as #1, but instead of importing from Github to Glitch you just upload the files (or copy/paste) them directly to Glitch. - -## Option 1 - Clone to computer, push to Github, import to Glitch (recommended) - -1. Fork the starting project code in GitHub. This repo contains: - * the server code, `server.js` - * A starting `index.html` file that you will edit as described below - * A package.json file that helps configure Glitch - * This README -2. Edit `index.html` to show the following information about you: - * your name and class at WPI (e.g. class of 2020) Note: Do not put any contact or personal information that you do not potentially want other people outside of this class to see. - * your major(s) and minor(s) - * previous computer science courses that you have taken at WPI - * your experience with the following technologies and methods (none, some, a lot) - * HTML - * CSS - * Java - * JavaScript - * Ruby - * Python - * unit testing -4. Complete some technical and/or design achievements (see below). -5. Test your project to make sure that when someone goes to your main page, it displays correctly. You can do this locally by simply running `node server.js` from within the assignment directory. - -6. Modify the README file according to the specification below. -7. Commit and push all your changes to GitHub. -8. Deploy your project to Glitch. You can do this by [importing the repo from GitHub](https://medium.com/glitch/import-code-from-anywhere-83fb60ea4875) -9. Ensure that your project has the proper naming scheme (guide follows) so we can find it. -9. Create and submit a Pull Request to the original repo. - -## Option 2 - Fork repo and import to Glitch, edit on Glitch, and then export back to GitHub -Most of these steps are the same as option 1, except that you being by creating a new project Glitch using this repo as a staring point (just choose New Project > Import from GitHub for this and then paste in the link to your repo). At the end, you can export your Glitch project to GitHub by [following these instructions](https://www.youtube.com/watch?time_continue=77&v=aWJFbtrgW4E&feature=emb_logo). *Note that the location of the projecct export feature in Glitch has moved from what they show in this video.* It's now located in Tools > Import and Export (tools is located in the bottom left of the Glitch editor). - -## Option 3 - Clone to computer, edit locally, push to GitHub, upload to Glitch -This is the same as option 1, except that for step 6 (Deploy to Glitch) you simply upload each file to your Glitch repository (using New File > Upload a File). - -Naming and URL Scheme ---- - -You must use a consistent naming scheme for all projects in this course. -If we can't find it, we can't grade it. - -By default Glitch often assigns your application a random name. To change it, click on the project dropdown menu in the upper left corner of Glitch. You will then see an additional text field displaying the project name in the resulting menu; click here to edit the name. - -The name scheme should be `a1-yourGitHubUsername`. -The `a1` will need to be updated to `a2`, `a3`, and so on in future projects. - -Achievements +Readme --- -Below are some suggested technical and design achievements. You can use these to help boost your grade up to an A and customize the assignment to your personal interests. These are recommended acheivements, but feel free to create/implement your own... just make sure you thoroughly describe what you did in your README and why it was challenging. ALL ACHIEVEMENTS MUST BE DESCRIBED IN YOUR README IN ORDER TO GET CREDIT FOR THEM. -*Technical* -1. (max 5 points) Style your page using CSS. Each style rule you apply will get you 1 extra point for a maximum of 5 points. Be sure to describe your style rules in your README. -2. (5 points) Add a simple JavaScript animation to the page. -3. (max 5 points) Experiment with other HTML tags (links, images, tables etc.) Each extra tag you use will get you 1 extra point for a maximum of 5 points. Be sure to describe the links you use in your README. +Lauren Wasserman +http://a1-lewasserman.glitch.me -*Design* -1. (10 points) Create a color palette using [color.adobe.com](https://color.adobe.com). Use all the colors in the palette in your webpage by implementing the appropriate CSS. Add a small screenshot of the color wheel for your color palette to your repo. -2. (5 points) Use a font from [Goolge Fonts](https://fonts.google.com) in your website. - -Resources ---- - -If you need a JavaScript/HTML/CSS refresher, see [HTML & CSS](https://wpi.primo.exlibrisgroup.com/discovery/fulldisplay?docid=alma9936730811904746&context=L&vid=01WPI_INST:Default&lang=en&search_scope=MyInst_and_CI&adaptor=Local%20Search%20Engine&tab=Everything&query=any,contains,Jon%20Duckett&offset=0) and/or [JavaScript Codeacademy](https://www.codecademy.com/en/tracks/javascript). - -If you need a Git/GitHub refreseher, see [GitHub Bootcamp](https://help.github.com/categories/bootcamp/), the [GitHub Guides](https://guides.github.com/) (especially the ones on Hello World, and Understanding the GitHub Flow, and Forking Projects), and [CodeSchool's Try Git Course](https://www.codeschool.com/courses/try-git). - -Sample Readme (delete the above when you're ready to submit, and modify the text below with your links and descriptions) ---- +**Please reload the page to see my animation of a yellow circle moving to the right along the screen** -Charlie Roberts -http://a1-charlieroberts.glitch.me +Also, I added eslint as a dependency in the package.json. After this I ran "npm install --no-optional" which I perhaps should not have done as it created a lot of files. The website still works as it should, so I hope that this is okay. This project shows ... ## Technical Achievements -- **Styled page with CSS**: Added rules for the p, li, and a selectors... +- **Styled page with CSS**: + 1. Added rules for body tags to change the background color of the site. + 2. Added rules for h1 and h2 tags to change the color of the text. + 3. Added rules for p tags to change the color for the text, add padding to the left and make the font size slightly bigger than the rest of the text on the site. + 4. Added rules for li tags to change the color of the text and increase the line height to add space between items. + 5. Added rules for ul tags to add padding on the left so that the items in the list were indented into the page. + 6. Added rules for dl tags to add padding on the left so that the items in the list were indented into the page. + 7. Added rules for table, th, and td tags to add a solid boarder for the table and to set the color of that border. I added rules to th tags to set their background color, the color for the text, the width of the cells, and the line-height for the text. I also added rules to the td tags to set their background color, the color of the text, and to add padding to the left and the right of the text in the cells. + 8. Added rules using an id selector (#quote) which controls for a span that contains a q and a cite tag to change the color of the text, the background color, the margin on the left of the span, the padding to the left and the right of the span, and the font-size for the text in the span. + 9. Added rules using an id selector (#wpi-logo) which controsls an img tag to set the height and width of the image as well as to set it to display inline-block so that I can have it on the same line as the heading/title for my website. + 10. Added rules using an id selector (#top-of-page) which controls a div that contains an a tag (which contains an img tag) and a h1 tag. This sets the white-space to nowrap so that the items inside can be side-by-side. It also sets display to flex and align-items to center so that the items are vertically aligned to each other. + 11. Added rules using an id selector (#by-logo) which controls the h1 tag that is to the right of the image on the page. These rules set the display to inline-block to allow it to be on the same line as the image and the padding on the left to allow for some more space between the h1 element and the image. + 12. Added rules using a class selector (.list-heading) which controls the h3 list headings on the page. It sets the text to bold and changes the color of the text. + 13. Added rules using an id selector (#animation-container) wihch controls a div tag which is the container for my animation of a moving circle. It makes the position of the container relative and sets the height such that there is enough room for the circle it holds. + 14. Added rules using an id selector (#animation) which controls a div tag which contains a circle which is animated. The style rules set the border radius to allow the div to be in the shape of a circle, set the width and the height to the same value, set the background color for the circle, and set the position of the circle to be absolute. + 15. Added root CSS variables for the colors in my color palette. I used these variables throughout my style rules to access my color palette. +- **Used other HTML tags**: + 1. img: I used an img tag to add an image of the WPI logo. + 2. a: I used an a tag to link the WPI logo to the WPI website. + 3. table: I used the table tag to contain my experience with the various languages. + 4. span: I used a span tag to contain a q tag and a cite tag to add a background color for them both. + 5. q: I used a q tag to add a quote. + 6. cite: I used a cite tag to cite the quote that I added. +- **Animations**: + 1. I added a confetti animation that goes over the site when it is freshed for 3 seconds. + 2. I added a dark yellow circle under the WPI logo and title of the page that slowly moves to 900px to the right whenever the page is loaded. It starts on the left of the page. To do this, I made a function which is called whenever the page is loaded. This function, moves the element to the right slowly pixel by pixel. ### Design Achievements -- **Used the Roboto Font from Google Fonts**: I used Roboto as the font for the primary copy text in my site. +- **Used the Montserrat Font from Google Fonts**: I used Montserrat as the font for the text in my site. +- **Created and Used a Color Palette**: Used color.adobe.com to create a color palette which I used for my site. diff --git a/WPI-logo.png b/WPI-logo.png new file mode 100644 index 0000000..d75b09c Binary files /dev/null and b/WPI-logo.png differ diff --git a/color-wheel.PNG b/color-wheel.PNG new file mode 100644 index 0000000..46dab83 Binary files /dev/null and b/color-wheel.PNG differ diff --git a/index.html b/index.html index 37ac8c3..bd9ab90 100644 --- a/index.html +++ b/index.html @@ -3,26 +3,182 @@ CS4241 Assignment 1 + - -

(The AST structure being the [ESTree](https://github.com/estree/estree) API with JSX extensions.) Separate from that, Espree may deviate from what Esprima outputs in terms of where and how comments are attached, as well as what additional information is available on AST nodes. That is to say, Espree may add more things to the AST nodes than Esprima does but the overall AST structure produced will be the same. + +Espree may also deviate from Esprima in the interface it exposes. + +## Contributing + +Issues and pull requests will be triaged and responded to as quickly as possible. We operate under the [ESLint Contributor Guidelines](http://eslint.org/docs/developer-guide/contributing), so please be sure to read them before contributing. If you're not sure where to dig in, check out the [issues](https://github.com/eslint/espree/issues). + +Espree is licensed under a permissive BSD 2-clause license. + +## Security Policy + +We work hard to ensure that Espree is safe for everyone and that security issues are addressed quickly and responsibly. Read the full [security policy](https://github.com/eslint/.github/blob/master/SECURITY.md). + +## Build Commands + +* `npm test` - run all linting and tests +* `npm run lint` - run all linting +* `npm run browserify` - creates a version of Espree that is usable in a browser + +## Differences from Espree 2.x + +* The `tokenize()` method does not use `ecmaFeatures`. Any string will be tokenized completely based on ECMAScript 6 semantics. +* Trailing whitespace no longer is counted as part of a node. +* `let` and `const` declarations are no longer parsed by default. You must opt-in by using an `ecmaVersion` newer than `5` or setting `sourceType` to `module`. +* The `esparse` and `esvalidate` binary scripts have been removed. +* There is no `tolerant` option. We will investigate adding this back in the future. + +## Known Incompatibilities + +In an effort to help those wanting to transition from other parsers to Espree, the following is a list of noteworthy incompatibilities with other parsers. These are known differences that we do not intend to change. + +### Esprima 1.2.2 + +* Esprima counts trailing whitespace as part of each AST node while Espree does not. In Espree, the end of a node is where the last token occurs. +* Espree does not parse `let` and `const` declarations by default. +* Error messages returned for parsing errors are different. +* There are two addition properties on every node and token: `start` and `end`. These represent the same data as `range` and are used internally by Acorn. + +### Esprima 2.x + +* Esprima 2.x uses a different comment attachment algorithm that results in some comments being added in different places than Espree. The algorithm Espree uses is the same one used in Esprima 1.2.2. + +## Frequently Asked Questions + +### Why another parser + +[ESLint](http://eslint.org) had been relying on Esprima as its parser from the beginning. While that was fine when the JavaScript language was evolving slowly, the pace of development increased dramatically and Esprima had fallen behind. ESLint, like many other tools reliant on Esprima, has been stuck in using new JavaScript language features until Esprima updates, and that caused our users frustration. + +We decided the only way for us to move forward was to create our own parser, bringing us inline with JSHint and JSLint, and allowing us to keep implementing new features as we need them. We chose to fork Esprima instead of starting from scratch in order to move as quickly as possible with a compatible API. + +With Espree 2.0.0, we are no longer a fork of Esprima but rather a translation layer between Acorn and Esprima syntax. This allows us to put work back into a community-supported parser (Acorn) that is continuing to grow and evolve while maintaining an Esprima-compatible parser for those utilities still built on Esprima. + +### Have you tried working with Esprima? + +Yes. Since the start of ESLint, we've regularly filed bugs and feature requests with Esprima and will continue to do so. However, there are some different philosophies around how the projects work that need to be worked through. The initial goal was to have Espree track Esprima and eventually merge the two back together, but we ultimately decided that building on top of Acorn was a better choice due to Acorn's plugin support. + +### Why don't you just use Acorn? + +Acorn is a great JavaScript parser that produces an AST that is compatible with Esprima. Unfortunately, ESLint relies on more than just the AST to do its job. It relies on Esprima's tokens and comment attachment features to get a complete picture of the source code. We investigated switching to Acorn, but the inconsistencies between Esprima and Acorn created too much work for a project like ESLint. + +We are building on top of Acorn, however, so that we can contribute back and help make Acorn even better. + +### What ECMAScript features do you support? + +Espree supports all ECMAScript 2020 features and partially supports ECMAScript 2021 features. + +Because ECMAScript 2021 is still under development, we are implementing features as they are finalized. Currently, Espree supports: + +* [Logical Assignment Operators](https://github.com/tc39/proposal-logical-assignment) +* [Numeric Separators](https://github.com/tc39/proposal-numeric-separator) + +See [finished-proposals.md](https://github.com/tc39/proposals/blob/master/finished-proposals.md) to know what features are finalized. + +### How do you determine which experimental features to support? + +In general, we do not support experimental JavaScript features. We may make exceptions from time to time depending on the maturity of the features. diff --git a/node_modules/espree/espree.js b/node_modules/espree/espree.js new file mode 100644 index 0000000..d806952 --- /dev/null +++ b/node_modules/espree/espree.js @@ -0,0 +1,177 @@ +/** + * @fileoverview Main Espree file that converts Acorn into Esprima output. + * + * This file contains code from the following MIT-licensed projects: + * 1.

We have no resources to support browserified version. Don't expect it to be + well tested. Don't expect fast fixes if something goes wrong there. +2. `!!js/function` in browser bundle will not work by default.

If you need advanced details (creating +your own tags), see [wiki](https://github.com/nodeca/js-yaml/wiki) and +[examples](https://github.com/nodeca/js-yaml/tree/master/examples) for more +info. + +``` javascript +const yaml = require('js-yaml'); +const fs = require('fs'); + +// Get document, or throw exception on error +try { + const doc = yaml.safeLoad(fs.readFileSync('/home/ixti/example.yml', 'utf8')); + console.log(doc); +} catch (e) { + console.log(e); +} +``` + + +### safeLoad (string [ , options ]) + +**Recommended loading way.** Parses `string` as single YAML document. Returns either a +plain object, a string or `undefined`, or throws `YAMLException` on error. By default, does +not support regexps, functions and undefined. This method is safe for untrusted data. + +options: + +- `filename` _(default: null)_ - string to be used as a file path in + error/warning messages. +- `onWarning` _(default: null)_ - function to call on warning messages. + Loader will call this function with an instance of `YAMLException` for each warning. +- `schema` _(default: `DEFAULT_SAFE_SCHEMA`)_ - specifies a schema to use. + - `FAILSAFE_SCHEMA` - only strings, arrays and plain objects: + http://www.yaml.org/spec/1.2/spec.html#id2802346 + - `JSON_SCHEMA` - all JSON-supported types: + http://www.yaml.org/spec/1.2/spec.html#id2803231 + - `CORE_SCHEMA` - same as `JSON_SCHEMA`: + http://www.yaml.org/spec/1.2/spec.html#id2804923 + - `DEFAULT_SAFE_SCHEMA` - all supported YAML types, without unsafe ones + (`!!js/undefined`, `!!js/regexp` and `!!js/function`): + http://yaml.org/type/ + - `DEFAULT_FULL_SCHEMA` - all supported YAML types. +- `json` _(default: false)_ - compatibility with JSON.parse behaviour. If true, then duplicate keys in a mapping will override values rather than throwing an error. + +NOTE: This function **does not** understand multi-document sources, it throws +exception on those. + +NOTE: JS-YAML **does not** support schema-specific tag resolution restrictions. +So, the JSON schema is not as strictly defined in the YAML specification. +It allows numbers in any notation, use `Null` and `NULL` as `null`, etc. +The core schema also has no such restrictions. It allows binary notation for integers. + + +### load (string [ , options ]) + +**Use with care with untrusted sources**. The same as `safeLoad()` but uses +`DEFAULT_FULL_SCHEMA` by default - adds some JavaScript-specific types: +`!!js/function`, `!!js/regexp` and `!!js/undefined`. For untrusted sources, you +must additionally validate object structure to avoid injections: + +``` javascript +const untrusted_code = '"toString": ! "function (){very_evil_thing();}"'; + +// I'm just converting that string, what could possibly go wrong? +require('js-yaml').load(untrusted_code) + '' +``` + + +### safeLoadAll (string [, iterator] [, options ]) + +Same as `safeLoad()`, but understands multi-document sources. Applies +`iterator` to each document if specified, or returns array of documents. + +``` javascript +const yaml = require('js-yaml'); + +yaml.safeLoadAll(data, function (doc) { + console.log(doc); +}); +``` + + +### loadAll (string [, iterator] [ , options ]) + +Same as `safeLoadAll()` but uses `DEFAULT_FULL_SCHEMA` by default. + + +### safeDump (object [ , options ]) + +Serializes `object` as a YAML document. Uses `DEFAULT_SAFE_SCHEMA`, so it will +throw an exception if you try to dump regexps or functions. However, you can +disable exceptions by setting the `skipInvalid` option to `true`. + +options: + +- `indent` _(default: 2)_ - indentation width to use (in spaces). +- `noArrayIndent` _(default: false)_ - when true, will not add an indentation level to array elements +- `skipInvalid` _(default: false)_ - do not throw on invalid types (like function + in the safe schema) and skip pairs and single values with such types. +- `flowLevel` (default: -1) - specifies level of nesting, when to switch from + block to flow style for collections. -1 means block style everwhere +- `styles` - "tag" => "style" map. Each tag may have own set of styles. +- `schema` _(default: `DEFAULT_SAFE_SCHEMA`)_ specifies a schema to use. +- `sortKeys` _(default: `false`)_ - if `true`, sort keys when dumping YAML. If a + function, use the function to sort the keys. +- `lineWidth` _(default: `80`)_ - set max line width. +- `noRefs` _(default: `false`)_ - if `true`, don't convert duplicate objects into references +- `noCompatMode` _(default: `false`)_ - if `true` don't try to be compatible with older + yaml versions. Currently: don't quote "yes", "no" and so on, as required for YAML 1.1 +- `condenseFlow` _(default: `false`)_ - if `true` flow sequences will be condensed, omitting the space between `a, b`. Eg. `'[a,b]'`, and omitting the space between `key: value` and quoting the key. Eg. `'{"a":b}'` Can be useful when using yaml for pretty URL query params as spaces are %-encoded. + +The following table show availlable styles (e.g. "canonical", +"binary"...) available for each tag (.e.g. !!null, !!int ...). Yaml +output is shown on the right side after `=>` (default setting) or `->`: + +``` none +!!null + "canonical" -> "~" + "lowercase" => "null" + "uppercase" -> "NULL" + "camelcase" -> "Null" + +!!int + "binary" -> "0b1", "0b101010", "0b1110001111010" + "octal" -> "01", "052", "016172" + "decimal" => "1", "42", "7290" + "hexadecimal" -> "0x1", "0x2A", "0x1C7A" + +!!bool + "lowercase" => "true", "false" + "uppercase" -> "TRUE", "FALSE" + "camelcase" -> "True", "False" + +!!float + "lowercase" => ".nan", '.inf' + "uppercase" -> ".NAN", '.INF' + "camelcase" -> ".NaN", '.Inf' +``` + +Example: + +``` javascript +safeDump (object, { + 'styles': { + '!!null': 'canonical' // dump null as ~ + }, + 'sortKeys': true // sort object keys +}); +``` + +### dump (object [ , options ]) + +Same as `safeDump()` but without limits (uses `DEFAULT_FULL_SCHEMA` by default). + + +Supported YAML types +-------------------- + +The list of standard YAML tags and corresponding JavaScipt types.

For the same input, it will choose a different output value depending on the type provided. For example, `parse('Number', '2')` will produce the number `2`, but `parse('String', '2')` will produce the string `"2"`. + +If you do not provide type information, and simply use `*`, levn will parse the input according the unambiguous "explicit" mode, which we will now detail - you can also set the `explicit` option to true manually in the [options](#options). + +* `"string"`, `'string'` are parsed as a String, eg. `"a msg"` is `"a msg"` +* `#date#` is parsed as a Date, eg. `#2011-11-11#` is `new Date('2011-11-11')` +* `/regexp/flags` is parsed as a RegExp, eg. `/re/gi` is `/re/gi` +* `undefined`, `null`, `NaN`, `true`, and `false` are all their JavaScript equivalents +* `[element1, element2, etc]` is an Array, and the casting procedure is recursively applied to each element. Eg. `[1,2,3]` is `[1,2,3]`. +* `(element1, element2, etc)` is an tuple, and the casting procedure is recursively applied to each element. Eg. `(1, a)` is `(1, a)` (is `[1, 'a']`). +* `{key1: val1, key2: val2, ...}` is an Object, and the casting procedure is recursively applied to each property. Eg. `{a: 1, b: 2}` is `{a: 1, b: 2}`. +* Any test which does not fall under the above, and which does not contain special characters (`[``]``(``)``{``}``:``,`) is a string, eg. `$12- blah` is `"$12- blah"`. + +If you do provide type information, you can make your input more concise as the program already has some information about what it expects. Please see the [type format](https://github.com/gkz/type-check#type-format) section of [type-check](https://github.com/gkz/type-check) for more information about how to specify types. There are some rules about what levn can do with the information: + +* If a String is expected, and only a String, all characters of the input (including any special ones) will become part of the output. Eg. `[({})]` is `"[({})]"`, and `"hi"` is `'"hi"'`. +* If a Date is expected, the surrounding `#` can be omitted from date literals. Eg. `2011-11-11` is `new Date('2011-11-11')`. +* If a RegExp is expected, no flags need to be specified, and the regex is not using any of the special characters,the opening and closing `/` can be omitted - this will have the affect of setting the source of the regex to the input. Eg. `regex` is `/regex/`. +* If an Array is expected, and it is the root node (at the top level), the opening `[` and closing `]` can be omitted. Eg. `1,2,3` is `[1,2,3]`. +* If a tuple is expected, and it is the root node (at the top level), the opening `(` and closing `)` can be omitted. Eg. `1, a` is `(1, a)` (is `[1, 'a']`). +* If an Object is expected, and it is the root node (at the top level), the opening `{` and closing `}` can be omitted. Eg `a: 1, b: 2` is `{a: 1, b: 2}`. + +If you list multiple types (eg. `Number | String`), it will first attempt to cast to the first type and then validate - if the validation fails it will move on to the next type and so forth, left to right. You must be careful as some types will succeed with any input, such as String. Thus put String at the end of your list. In non-explicit mode, Date and RegExp will succeed with a large variety of input - also be careful with these and list them near the end if not last in your list. + +Whitespace between special characters and elements is inconsequential. + +## Options + +Options is an object. It is an optional parameter to the `parse` and `parsedTypeParse` functions. + +### Explicit + +A `Boolean`. By default it is `false`. + +__Example:__ + +```js +parse('RegExp', 're', {explicit: false}); // /re/ +parse('RegExp', 're', {explicit: true}); // Error: ... does not type check... +parse('RegExp | String', 're', {explicit: true}); // 're' +``` + +`explicit` sets whether to be in explicit mode or not.

For more information about `typeOf` and `validate`, please see the [custom types](https://github.com/gkz/type-check#custom-types) section of type-check. + +`cast` is a function which receives three arguments, the value under question, options, and the typesCast function. In `cast`, attempt to cast the value into the specified type. If you are successful, return an object in the format `{type: 'Just', value: CAST-VALUE}`, if you know it won't work, return `{type: 'Nothing'}`. You can use the `typesCast` function to cast any child values. Remember to pass `options` to it. In your function you can also check for `options.explicit` and act accordingly. + +## Technical About + +`levn` is written in [LiveScript](http://livescript.net/) - a language that compiles to JavaScript.

Not setting this is kind of + silly, since that's the whole purpose of this lib, but it defaults + to `Infinity`. Setting it to a non-number or negative number will + throw a `TypeError`. Setting it to 0 makes it be `Infinity`. +* `maxAge` Maximum age in ms. Items are not pro-actively pruned out + as they age, but if you try to get an item that is too old, it'll + drop it and return undefined instead of giving it to you. + Setting this to a negative value will make everything seem old! + Setting it to a non-number will throw a `TypeError`. +* `length` Function that is used to calculate the length of stored + items. If you're storing strings or buffers, then you probably want + to do something like `function(n, key){return n.length}`. The default is + `function(){return 1}`, which is fine if you want to store `max` + like-sized things. The item is passed as the first argument, and + the key is passed as the second argumnet. +* `dispose` Function that is called on items when they are dropped + from the cache. This can be handy if you want to close file + descriptors or do other cleanup tasks when items are no longer + accessible. Called with `key, value`. It's called *before* + actually removing the item from the internal cache, so if you want + to immediately put it back in, you'll have to do that in a + `nextTick` or `setTimeout` callback or it won't do anything. +* `stale` By default, if you set a `maxAge`, it'll only actually pull + stale items out of the cache when you `get(key)`. (That is, it's + not pre-emptively doing a `setTimeout` or anything.) If you set + `stale:true`, it'll return the stale value before deleting it. If + you don't set this, then it'll return `undefined` when you try to + get a stale entry, as if it had already been deleted. +* `noDisposeOnSet` By default, if you set a `dispose()` method, then + it'll be called whenever a `set()` operation overwrites an existing + key. If you set this option, `dispose()` will only be called when a + key falls out of the cache, not when it is overwritten. +* `updateAgeOnGet` When using time-expiring entries with `maxAge`, + setting this to `true` will make each item's effective time update + to the current time whenever it is retrieved from cache, causing it + to not expire. (It can still fall out of cache based on recency of + use, of course.) + +## API + +* `set(key, value, maxAge)` +* `get(key) => value` + + Both of these will update the "recently used"-ness of the key. + They do what you think. `maxAge` is optional and overrides the + cache `maxAge` option if provided. + + If the key is not found, `get()` will return `undefined`. + + The key and val can be any value. + +* `peek(key)` + + Returns the key value (or `undefined` if not found) without + updating the "recently used"-ness of the key. + + (If you find yourself using this a lot, you *might* be using the + wrong sort of data structure, but there are some use cases where + it's handy.) + +* `del(key)` + + Deletes a key out of the cache. + +* `reset()` + + Clear the cache entirely, throwing away all values. + +* `has(key)` + + Check if a key is in the cache, without updating the recent-ness + or deleting it for being stale. + +* `forEach(function(value,key,cache), [thisp])` + + Just like `Array.prototype.forEach`. Iterates over all the keys + in the cache, in order of recent-ness. (Ie, more recently used + items are iterated over first.) + +* `rforEach(function(value,key,cache), [thisp])` + + The same as `cache.forEach(...)` but items are iterated over in + reverse order. (ie, less recently used items are iterated over + first.) + +* `keys()` + + Return an array of the keys in the cache. + +* `values()` + + Return an array of the values in the cache. + +* `length` + + Return total length of objects in cache taking into account + `length` options function. + +* `itemCount` + + Return total quantity of objects currently in cache. Note, that + `stale` (see options) items are returned as part of this item + count. + +* `dump()` + + Return an array of the cache entries ready for serialization and usage + with 'destinationCache.load(arr)`. + +* `load(cacheEntriesArray)` + + Loads another cache entries array, obtained with `sourceCache.dump()`, + into the cache.

Each item in the row + corresponds to a single path-part. For example, the pattern + `{a,b/c}/d` would expand to a set of patterns like: + + [ [ a, d ] + , [ b, c, d ] ] + + If a portion of the pattern doesn't have any "magic" in it + (that is, it's something like `"foo"` rather than `fo*o?`), then it + will be left as a string rather than converted to a regular + expression. + +* `regexp` Created by the `makeRe` method. A single regular expression + expressing the entire pattern. This is useful in cases where you wish + to use the pattern somewhat like `fnmatch(3)` with `FNM_PATH` enabled. +* `negate` True if the pattern is negated. +* `comment` True if the pattern is a comment. +* `empty` True if the pattern is `""`. + +### Methods + +* `makeRe` Generate the `regexp` member if necessary, and return it. + Will return `false` if the pattern is invalid. +* `match(fname)` Return true if the filename matches the pattern, or + false otherwise. +* `matchOne(fileArray, patternArray, partial)` Take a `/`-split + filename, and match it against a single row in the `regExpSet`. This + method is mainly for internal use, but is exposed so that it can be + used by a glob-walker that needs to avoid excessive filesystem calls. + +All other methods are internal, and will be called as necessary. + +### minimatch(path, pattern, options) + +Main export. Tests a path against the pattern using the options. + +```javascript +var isJS = minimatch(file, "*.js", { matchBase: true }) +``` + +### minimatch.filter(pattern, options) + +Returns a function that tests its +supplied argument, suitable for use with `Array.filter`. Example: + +```javascript +var javascripts = fileList.filter(minimatch.filter("*.js", {matchBase: true})) +``` + +### minimatch.match(list, pattern, options) + +Match against the list of +files, in the style of fnmatch or glob. If nothing is matched, and +options.nonull is set, then return a list containing the pattern itself. + +```javascript +var javascripts = minimatch.match(fileList, "*.js", {matchBase: true})) +``` + +### minimatch.makeRe(pattern, options) + +Make a regular expression object from the pattern. + +## Options + +All options are `false` by default. + +### debug + +Dump a ton of stuff to stderr. + +### nobrace + +Do not expand `{a,b}` and `{1..3}` brace sets. + +### noglobstar + +Disable `**` matching against multiple folder names. + +### dot + +Allow patterns to match filenames starting with a period, even if +the pattern does not explicitly have a period in that spot. + +Note that by default, `a/**/b` will **not** match `a/.d/b`, unless `dot` +is set. + +### noext + +Disable "extglob" style patterns like `+(a|b)`. + +### nocase + +Perform a case-insensitive match. + +### nonull + +When a match is not found by `minimatch.match`, return a list containing +the pattern itself if this option is set. When not set, an empty list +is returned if there are no matches. + +### matchBase + +If set, then patterns without slashes will be matched +against the basename of the path if it contains slashes. For example, +`a?b` would match the path `/xyz/123/acb`, but not `/xyz/acb/123`. + +### nocomment + +Suppress the behavior of treating `#` at the start of a pattern as a +comment. + +### nonegate + +Suppress the behavior of treating a leading `!` character as negation. + +### flipNegate + +Returns from negate expressions the same as if they were not negated. +(Ie, true on a hit, false on a miss.) + + +## Comparisons to other fnmatch/glob implementations + +While strict compliance with the existing standards is a worthwhile +goal, some discrepancies exist between minimatch and other +implementations, and are intentional. + +If the pattern starts with a `!` character, then it is negated. Set the +`nonegate` flag to suppress this behavior, and treat leading `!` +characters normally. This is perhaps relevant if you wish to start the +pattern with a negative extglob pattern like `!(a|B)`. Multiple `!` +characters at the start of a pattern will negate the pattern multiple +times. + +If a pattern starts with `#`, then it is treated as a comment, and +will not match anything. Use `\#` to match a literal `#` at the +start of a line, or set the `nocomment` flag to suppress this behavior. + +The double-star character `**` is supported by default, unless the +`noglobstar` flag is set. This is supported in the manner of bsdglob +and bash 4.1, where `**` only has special significance if it is the only +thing in a path part. That is, `a/**/b` will match `a/x/y/b`, but +`a/**b` will not. + +If an escaped pattern has no matches, and the `nonull` flag is set, +then minimatch.match returns the pattern as-provided, rather than +interpreting the character escapes. For example, +`minimatch.match([], "\\*a\\?")` will return `"\\*a\\?"` rather than +`"*a?"`. This is akin to setting the `nullglob` option in bash, except +that it does not resolve escaped pattern characters. + +If brace expansion is not disabled, then it is performed before any +other interpretation of the glob pattern. Thus, a pattern like +`+(a|{b),c)}`, which would not be valid in bash or zsh, is expanded +**first** into the set of `+(a|b)` and `+(a|c)`, and those patterns are +checked for validity. Since those two are valid, matching proceeds. diff --git a/node_modules/minimatch/minimatch.js b/node_modules/minimatch/minimatch.js new file mode 100644 index 0000000..5b5f8cf --- /dev/null +++ b/node_modules/minimatch/minimatch.js @@ -0,0 +1,923 @@ +module.exports = minimatch +minimatch.Minimatch = Minimatch + +var path = { sep: '/' } +try { + path = require('path') +} catch (er) {} + +var GLOBSTAR = minimatch.GLOBSTAR = Minimatch.GLOBSTAR = {} +var expand = require('brace-expansion') + +var plTypes = { + '!': { open: '(?:(?!(?:', close: '))[^/]*?)'}, + '?': { open: '(?:', close: ')?' }, + '+': { open: '(?:', close: ')+' }, + '*': { open: '(?:', close: ')*' }, + '@': { open: '(?:', close: ')' } +} + +// any single thing other than / +// don't need to escape / when using new RegExp() +var qmark = '[^/]' + +// * => any number of characters +var star = qmark + '*?' + +// ** when dots are allowed.

The one currently supported option is `oneValuePerFlag`, this only allows one array value per flag. This is useful if your potential values contain a comma. +* `mergeRepeatedObjects` is an optional boolean (defaults to `false`) - when set to `true` and an option contains an object value and is repeated, the subsequent values for the flag will be merged rather than overwriting the original value - eg. option `g` of type `Object`: `-g a:1 -g b:2 -g c:3,d:4` will result in `{a: 1, b: 2, c: 3, d: 4}` +* `dependsOn` is an optional string or array of strings - if simply a string (the name of another option), it will make sure that that other option is set, if an array of strings, depending on whether `'and'` or `'or'` is first, it will either check whether all (`['and', 'option-a', 'option-b']`), or at least one (`['or', 'option-a', 'option-b']`) other options are set +* `description` is an optional string, which will be displayed next to the option in the help text +* `longDescription` is an optional string, it will be displayed instead of the `description` when `generateHelpForOption` is used +* `example` is an optional string or array of strings with example(s) for the option - these will be displayed when `generateHelpForOption` is used + +#### Help Style Properties +* `aliasSeparator` is an optional string, separates multiple names from each other - default: ' ,' +* `typeSeparator` is an optional string, separates the type from the names - default: ' ' +* `descriptionSeparator` is an optional string , separates the description from the padded name and type - default: ' ' +* `initialIndent` is an optional int - the amount of indent for options - default: 2 +* `secondaryIndent` is an optional int - the amount of indent if wrapped fully (in addition to the initial indent) - default: 4 +* `maxPadFactor` is an optional number - affects the default level of padding for the names/type, it is multiplied by the average of the length of the names/type - default: 1.5 + +## Argument Format +At the highest level there are two types of arguments: named, and positional. + +Name arguments of any length are prefixed with `--` (eg. `--go`), and those of one character may be prefixed with either `--` or `-` (eg. `-g`). + +There are two types of named arguments: boolean flags (eg. `--problemo`, `-p`) which take no value and result in a `true` if they are present, the falsey `undefined` if they are not present, or `false` if present and explicitly prefixed with `no` (eg. `--no-problemo`). Named arguments with values (eg. `--tseries 800`, `-t 800`) are the other type. If the option has a type `Boolean` it will automatically be made into a boolean flag. Any other type results in a named argument that takes a value. + +For more information about how to properly set types to get the value you want, take a look at the [type check](https://github.com/gkz/type-check) and [levn](https://github.com/gkz/levn) pages. + +You can group single character arguments that use a single `-`, however all except the last must be boolean flags (which take no value). The last may be a boolean flag, or an argument which takes a value - eg. `-ba 2` is equivalent to `-b -a 2`. + +Positional arguments are all those values which do not fall under the above - they can be anywhere, not just at the end. For example, in `cmd -b one -a 2 two` where `b` is a boolean flag, and `a` has the type `Number`, there are two positional arguments, `one` and `two`. + +Everything after an `--` is positional, even if it looks like a named argument. + +You may optionally use `=` to separate option names from values, for example: `--count=2`. + +If you specify the option `NUM`, then any argument using a single `-` followed by a number will be valid and will set the value of `NUM`. Eg. `-2` will be parsed into `NUM: 2`. + +If duplicate named arguments are present, the last one will be taken. + +## Technical About +`optionator` is written in [LiveScript](http://livescript.net/) - a language that compiles to JavaScript. It uses [levn](https://github.com/gkz/levn) to cast arguments to their specified type, and uses [type-check](https://github.com/gkz/type-check) to validate values. It also uses the [prelude.ls](http://preludels.com/) library. diff --git a/node_modules/optionator/lib/help.js b/node_modules/optionator/lib/help.js new file mode 100644 index 0000000..59e6f96 --- /dev/null +++ b/node_modules/optionator/lib/help.js @@ -0,0 +1,260 @@ +// Generated by LiveScript 1.6.0 +(function(){ + var ref$, id, find, sort, min, max, map, unlines, nameToRaw, dasherize, naturalJoin, wordWrap, wordwrap, getPreText, setHelpStyleDefaults, generateHelpForOption, generateHelp; + ref$ = require('prelude-ls'), id = ref$.id, find = ref$.find, sort = ref$.sort, min = ref$.min, max = ref$.max, map = ref$.map, unlines = ref$.unlines; + ref$ = require('./util'), nameToRaw = ref$.nameToRaw, dasherize = ref$.dasherize, naturalJoin = ref$.naturalJoin; + wordWrap = require('word-wrap'); + wordwrap = function(a, b){ + var ref$, indent, width; + ref$ = b === undefined + ?

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 <2.4.0-0` +* `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 version 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.

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`.

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)`: 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 +* `simplifyRange(versions, range)`: Return a "simplified" range that + matches the same items in `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 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. 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` + +## Exported Modules + + + +You may pull in just the part of this semver utility that you need, if you +are sensitive to packing and tree-shaking concerns.

If not specified, arguments will be placed in the same order as the placeholders in the input string. +* An optional `+` sign that forces to preceed the result with a plus or minus sign on numeric values. By default, only the `-` sign is used on negative numbers. +* An optional padding specifier that says what character to use for padding (if specified). Possible values are `0` or any other character precedeed by a `'` (single quote). The default is to pad with *spaces*. +* An optional `-` sign, that causes sprintf to left-align the result of this placeholder. The default is to right-align the result. +* An optional number, that says how many characters the result should have. If the value to be returned is shorter than this number, the result will be padded. When used with the `j` (JSON) type specifier, the padding length specifies the tab size used for indentation. +* An optional precision modifier, consisting of a `.` (dot) followed by a number, that says how many digits should be displayed for floating point numbers. When used with the `g` type specifier, it specifies the number of significant digits. When used on a string, it causes the result to be truncated. +* A type specifier that can be any of: + * `%` — yields a literal `%` character + * `b` — yields an integer as a binary number + * `c` — yields an integer as the character with that ASCII value + * `d` or `i` — yields an integer as a signed decimal number + * `e` — yields a float using scientific notation + * `u` — yields an integer as an unsigned decimal number + * `f` — yields a float as is; see notes on precision above + * `g` — yields a float as is; see notes on precision above + * `o` — yields an integer as an octal number + * `s` — yields a string as is + * `x` — yields an integer as a hexadecimal number (lower-case) + * `X` — yields an integer as a hexadecimal number (upper-case) + * `j` — yields a JavaScript object or array as a JSON encoded string + +## JavaScript `vsprintf` +`vsprintf` is the same as `sprintf` except that it accepts an array of arguments, rather than a variable number of arguments: + + vsprintf("The first 4 letters of the english alphabet are: %s, %s, %s and %s", ["a", "b", "c", "d"]) + +## Argument swapping +You can also swap the arguments.

Specifically, + +```js +{}.toString.call(VALUE).slice(8, -1) +{}.toString.call(true).slice(8, -1) // 'Boolean' +``` +A basic type, eg. `Number`, uses this check. This is much more versatile than using `typeof` - for example, with `document`, `typeof` produces `'object'` which isn't that useful, and our technique produces `'HTMLDocument'`. + +You may check for multiple types by separating types with a `|`. The checker proceeds from left to right, and passes if the value is any of the types - eg. `String | Boolean` first checks if the value is a string, and then if it is a boolean. If it is none of those, then it returns false. + +Adding a `Maybe` in front of a list of multiple types is the same as also checking for `Null` and `Undefined` - eg. `Maybe String` is equivalent to `Undefined | Null | String`. + +You may add a comment to remind you of what the type is for by following an identifier with a `::` before a type (or multiple types). The comment is simply thrown out. + +The wildcard `*` matches all types. + +There are three types of structures for checking the contents of a value: 'fields', 'tuple', and 'array'. + +If used by itself, a 'fields' structure will pass with any type of object as long as it is an instance of `Object` and the properties pass - this allows for duck typing - eg. `{x: Boolean}`. + +To check if the properties pass, and the value is of a certain type, you can specify the type - eg. `Error{message: String}`. + +If you want to make a field optional, you can simply use `Maybe` - eg. `{x: Boolean, y: Maybe String}` will still pass if `y` is undefined (or null). + +If you don't care if the value has properties beyond what you have specified, you can use the 'etc' operator `...` - eg. `{x: Boolean, ...}` will match an object with an `x` property that is a boolean, and with zero or more other properties. + +For an array, you must specify one or more types (separated by `|`) - it will pass for something of any length as long as each element passes the types provided - eg. `[Number]`, `[Number | String]`. + +A tuple checks for a fixed number of elements, each of a potentially different type. Each element is separated by a comma - eg. `(String, Number)`. + +An array and tuple structure check that the value is of type `Array` by default, but if another type is specified, they will check for that instead - eg. `Int32Array[Number]`. You can use the wildcard `*` to search for any type at all. + +Check out the [type precedence](https://github.com/zaboco/type-precedence) library for type-check. + +## Options + +Options is an object. It is an optional parameter to the `typeCheck` and `parsedTypeCheck` functions. The only current option is `customTypes`. + + +### Custom Types + +__Example:__ + +```js +var options = { + customTypes: { + Even: { + typeOf: 'Number', + validate: function(x) { + return x % 2 === 0; + } + } + } +}; +typeCheck('Even', 2, options); // true +typeCheck('Even', 3, options); // false +``` + +`customTypes` allows you to set up custom types for validation. The value of this is an object. The keys of the object are the types you will be matching. Each value of the object will be an object having a `typeOf` property - a string, and `validate` property - a function. + +The `typeOf` property is the type the value should be (optional - if not set only `validate` will be used), and `validate` is a function which should return true if the value is of that type. `validate` receives one parameter, which is the value that we are checking. + +## Technical About + +`type-check` is written in [LiveScript](http://livescript.net/) - a language that compiles to JavaScript.
