When reading the subdomain of an xip.io request, you will get a different value compared to a local pow request. The reason for this is that the tld length is 1 by default, but an xip.io request has a tld length of 6. This gem inserts a middleware that corrects the tld length config of rails on the fly so that you can use local and xip requests at the same time without restarting the server.
Little helper for the classes Date, DateTime and Time. // date_time_compare.rb: Allows to compare Date and Time objects (allows to sort by mixed Date/Time-keys). // date_creator.rb: New date creations: Date#new_by_mday: Allows "Third sunday in june 2010"... // date_locale.rb: Localization of Date, DateTime and Time. strftime gets a optional parameter to determine the language. Default is en, or if locale is used the current locale.
A class that wraps the Time class and makes it easy to work with most known time values, including various time strings, automatically converting them to Time values, and perform tolerant comparisons. Several time classes, and the String class, are extended with the ".easy_time" method to perform an auto-conversion. A tolerant comparison allows for times from differing systems to be compared, even when the systems are out of sync, using the relationship operators and methods like "newer?", "older?", "same?" and "between?". A tolerant comparison for equality is where the difference of two values is less than the tolerance value (1 minute by default). The tolerance can be configured, even set to zero. Finally, all of the Time class and instance methods are available on the EasyTime class and instances.
Helium is a frontend responsive web framework for rapid prototyping and production-ready development using HTML5 and CSS3. In many ways it is similar to both Twitter Bootstrap and ZURB Foundation - in fact, it uses bits of their code. Unlike either of these two frameworks, however, Helium is designed to be much more lightweight and easier to tinker with. Think of it as a classic car where you can pop open the hood and easily work on the engine. The compiled default CSS file weighs in at a comparatively tiny 30k, versus approximately 100k for Bootstrap and almost 200k for Foundation.
== DESCRIPTION: websitary (formerly known as websitiary with an extra "i") monitors webpages, rss feeds, podcasts etc. It reuses other programs (w3m, diff etc.) to do most of the actual work. By default, it works on an ASCII basis, i.e. with the output of text-based webbrowsers like w3m (or lynx, links etc.) as the output can easily be post-processed. It can also work with HTML and highlight new items. This script was originally planned as a ruby-based websec replacement. By default, this script will use w3m to dump HTML pages and then run diff over the current page and the previous backup. Some pages are better viewed with lynx or links. Downloaded documents (HTML or ASCII) can be post-processed (e.g., filtered through some ruby block that extracts elements via hpricot and the like). Please see the configuration options below to find out how to change this globally or for a single source. This user manual is also available as PDF[http://websitiary.rubyforge.org/websitary.pdf]. == FEATURES/PROBLEMS: * Handle webpages, rss feeds (optionally save attachments in podcasts etc.) * Compare webpages with previous backups * Display differences between the current version and the backup * Provide hooks to post-process the downloaded documents and the diff * Display a one-page report summarizing all news * Automatically open the report in your favourite web-browser * Experimental: Download webpages on defined intervalls and generate incremental diffs.
== DESCRIPTION: Charlie is a library for genetic algorithms (GA) and genetic programming (GP). == FEATURES: - Quickly develop GAs by combining several parts (genotype, selection, crossover, mutation) provided by the library. - Sensible defaults are provided with any genotype, so often you only need to define a fitness function. - Easily replace any of the parts by your own code. - Test different strategies in GA, and generate reports comparing them. Example report: http://charlie.rubyforge.org/example_report.html == INSTALL: * sudo gem install charlie == EXAMPLES: This example solves a TSP problem (also quiz #142): N=5 CITIES = (0...N).map{|i| (0...N).map{|j| [i,j] } }.inject{|a,b|a+b} class TSP < PermutationGenotype(CITIES.size) def fitness d=0 (genes + [genes[0]]).each_cons(2){|a,b| a,b=CITIES[a],CITIES[b] d += Math.sqrt( (a[0]-b[0])**2 + (a[1]-b[1])**2 ) } -d # lower distance -> higher fitness. end use EdgeRecombinationCrossover, InversionMutator end Population.new(TSP,20).evolve_on_console(50) This example finds a polynomial which approximates cos(x) class Cos < TreeGenotype([proc{3*rand-1.5},:x], [:-@], [:+,:*,:-]) def fitness -[0,0.33,0.66,1].map{|x| (eval_genes(:x=>x) - Math.cos(x)).abs }.max end use TournamentSelection(4) end Population.new(Cos).evolve_on_console(500)
Value Value is a library for defining immutable value objects in Ruby. A value object is an object whose equality to other objects is determined by its value, not its identity, think dates and amounts of money. A value object should also be immutable, as you don’t want the date “2013-04-22” itself to change but the current date to change from “2013-04-22” to “2013-04-23”. That is, you don’t want entries in a calendar for 2013-04-22 to move to 2013-04-23 simply because the current date changes from 2013-04-22 to 2013-04-23. A value object consists of one or more attributes stored in instance variables. Value sets up an #initialize method for you that let’s you set these attributes, as, value objects being immutable, this’ll be your only chance to do so. Value also adds equality checks ‹#==› and ‹#eql?› (which are themselves equivalent), a ‹#hash› method, a nice ‹#inspect› method, and a protected attribute reader for each attribute. You may of course add any additional methods that your value object will benefit from. That’s basically all there’s too it. Let’s now look at using the Value library. § Usage You create value object class by invoking ‹#Value› inside the class (module) you wish to make into a value object class. Let’s create a class that represent points on a plane: class Point Value :x, :y end A ‹Point› is thus a value object consisting of two sub-values ‹x› and ‹y› (the coordinates). Just from invoking ‹#Value›, a ‹Point› object will have a constructor that takes two arguments to set instance variables ‹@x› and ‹@y›, equality checks ‹#==› and ‹#eql?› (which are the same), a ‹#hash› method, a nice ‹#inspect› method, and two protected attribute readers ‹#x› and ‹#y›. We can thus already creat ‹Point›s: origo = Point.new(0, 0) The default of making the attribute readers protected is often good practice, but for a ‹Point› it probably makes sense to be able to access its coordinates: class Point public(*attributes) end This’ll make all attributes of ‹Point› public. You can of course choose to only make certain attributes public: class Point public :x end Note that this public is standard Ruby functionality. Adding a method to ‹Point› is of course also possible and very much Rubyish: class Point def distance(other) Math.sqrt((other.x - x)**2 + (other.y - y)**2) end end For some value object classes you might want to support optional attributes. This is done by providing a default value for the attribute, like so: class Money Value :amount, [:currency, :USD] end Here, the ‹currency› attribute will default to ‹:USD›. You can create ‹Money› via dollars = Money.new(2) but also kronor = Money.new(2, :SEK) All required attributes must come before any optional attributes. Splat attributes are also supported: class List Value :'*elements' end empty = List.new suits = List.new(:spades, :hearts, :diamonds, :clubs) Splat attributes are optional. Finally, block attributes are also available: class Block Value :'&block' end block = Block.new{ |e| e * 2 } Block attributes are optional. Comparison beyond ‹#==› is possible by specifingy the ‹:comparable› option to ‹#Value›, listing one or more attributes that should be included in the comparison: class Vector Value :a, :b, :comparable => :a end Note that equality (‹#==› and ‹#eql?›) is always defined based on all attributes, regardless of arguments to ‹:comparable›. Here we say that comparisons between ‹Vector›s should be made between the values of the ‹a› attribute only. We can also make comparisons between all attributes of a value object: class Vector Value :a, :b, :comparable => true end To sum things up, let’s use all possible arguments to ‹#Value› at once: class Method Value :file, :line, [:name, 'unnamed'], :'*args', :'&block', :comparable => [:file, :line] end A ‹Method› consists of file and line information, a possible name, some arguments, possibly a block, and is comparable on the file and line on which they appear.

Diff and patch tables
This documentation describes LaunchDarkly's REST API. To access the complete OpenAPI spec directly, use [Get OpenAPI spec](https://launchdarkly.com/docs/api/other/get-openapi-spec). To learn how to use LaunchDarkly using the user interface (UI) instead, read our [product documentation](https://launchdarkly.com/docs/home). ## Authentication LaunchDarkly's REST API uses the HTTPS protocol with a minimum TLS version of 1.2. All REST API resources are authenticated with either [personal or service access tokens](https://launchdarkly.com/docs/home/account/api), or session cookies. Other authentication mechanisms are not supported. You can manage personal access tokens on your [**Authorization**](https://app.launchdarkly.com/settings/authorization) page in the LaunchDarkly UI. LaunchDarkly also has SDK keys, mobile keys, and client-side IDs that are used by our server-side SDKs, mobile SDKs, and JavaScript-based SDKs, respectively. **These keys cannot be used to access our REST API**. These keys are environment-specific, and can only perform read-only operations such as fetching feature flag settings. | Auth mechanism | Allowed resources | Use cases | | ----------------------------------------------------------------------------------------------- | ----------------------------------------------------------------------------------------------------- | -------------------------------------------------- | | [Personal or service access tokens](https://launchdarkly.com/docs/home/account/api) | Can be customized on a per-token basis | Building scripts, custom integrations, data export. | | SDK keys | Can only access read-only resources specific to server-side SDKs. Restricted to a single environment. | Server-side SDKs | | Mobile keys | Can only access read-only resources specific to mobile SDKs, and only for flags marked available to mobile keys. Restricted to a single environment. | Mobile SDKs | | Client-side ID | Can only access read-only resources specific to JavaScript-based client-side SDKs, and only for flags marked available to client-side. Restricted to a single environment. | Client-side JavaScript | > #### Keep your access tokens and SDK keys private > > Access tokens should _never_ be exposed in untrusted contexts. Never put an access token in client-side JavaScript, or embed it in a mobile application. LaunchDarkly has special mobile keys that you can embed in mobile apps. If you accidentally expose an access token or SDK key, you can reset it from your [**Authorization**](https://app.launchdarkly.com/settings/authorization) page. > > The client-side ID is safe to embed in untrusted contexts. It's designed for use in client-side JavaScript. ### Authentication using request header The preferred way to authenticate with the API is by adding an `Authorization` header containing your access token to your requests. The value of the `Authorization` header must be your access token. Manage personal access tokens from the [**Authorization**](https://app.launchdarkly.com/settings/authorization) page. ### Authentication using session cookie For testing purposes, you can make API calls directly from your web browser. If you are logged in to the LaunchDarkly application, the API will use your existing session to authenticate calls. Depending on the permissions granted as part of your [role](https://launchdarkly.com/docs/home/account/roles), you may not have permission to perform some API calls. You will receive a `401` response code in that case. > ### Modifying the Origin header causes an error > > LaunchDarkly validates that the Origin header for any API request authenticated by a session cookie matches the expected Origin header. The expected Origin header is `https://app.launchdarkly.com`. > > If the Origin header does not match what's expected, LaunchDarkly returns an error. This error can prevent the LaunchDarkly app from working correctly. > > Any browser extension that intentionally changes the Origin header can cause this problem. For example, the `Allow-Control-Allow-Origin: *` Chrome extension changes the Origin header to `http://evil.com` and causes the app to fail. > > To prevent this error, do not modify your Origin header. > > LaunchDarkly does not require origin matching when authenticating with an access token, so this issue does not affect normal API usage. ## Representations All resources expect and return JSON response bodies. Error responses also send a JSON body. To learn more about the error format of the API, read [Errors](https://launchdarkly.com/docs/api#errors). In practice this means that you always get a response with a `Content-Type` header set to `application/json`. In addition, request bodies for `PATCH`, `POST`, and `PUT` requests must be encoded as JSON with a `Content-Type` header set to `application/json`. ### Summary and detailed representations When you fetch a list of resources, the response includes only the most important attributes of each resource. This is a _summary representation_ of the resource. When you fetch an individual resource, such as a single feature flag, you receive a _detailed representation_ of the resource. The best way to find a detailed representation is to follow links. Every summary representation includes a link to its detailed representation. ### Expanding responses Sometimes the detailed representation of a resource does not include all of the attributes of the resource by default. If this is the case, the request method will clearly document this and describe which attributes you can include in an expanded response. To include the additional attributes, append the `expand` request parameter to your request and add a comma-separated list of the attributes to include. For example, when you append `?expand=members,maintainers` to the [Get team](https://launchdarkly.com/docs/api/teams/get-team) endpoint, the expanded response includes both of these attributes. ### Links and addressability The best way to navigate the API is by following links. These are attributes in representations that link to other resources. The API always uses the same format for links: - Links to other resources within the API are encapsulated in a `_links` object - If the resource has a corresponding link to HTML content on the site, it is stored in a special `_site` link Each link has two attributes: - An `href`, which contains the URL - A `type`, which describes the content type For example, a feature resource might return the following: ```json { "_links": { "parent": { "href": "/api/features", "type": "application/json" }, "self": { "href": "/api/features/sort.order", "type": "application/json" } }, "_site": { "href": "/features/sort.order", "type": "text/html" } } ``` From this, you can navigate to the parent collection of features by following the `parent` link, or navigate to the site page for the feature by following the `_site` link. Collections are always represented as a JSON object with an `items` attribute containing an array of representations. Like all other representations, collections have `_links` defined at the top level. Paginated collections include `first`, `last`, `next`, and `prev` links containing a URL with the respective set of elements in the collection. ## Updates Resources that accept partial updates use the `PATCH` verb. Most resources support the [JSON patch](https://launchdarkly.com/docs/api#updates-using-json-patch) format. Some resources also support the [JSON merge patch](https://launchdarkly.com/docs/api#updates-using-json-merge-patch) format, and some resources support the [semantic patch](https://launchdarkly.com/docs/api#updates-using-semantic-patch) format, which is a way to specify the modifications to perform as a set of executable instructions. Each resource supports optional [comments](https://launchdarkly.com/docs/api#updates-with-comments) that you can submit with updates. Comments appear in outgoing webhooks, the audit log, and other integrations. When a resource supports both JSON patch and semantic patch, we document both in the request method. However, the specific request body fields and descriptions included in our documentation only match one type of patch or the other. ### Updates using JSON patch [JSON patch](https://datatracker.ietf.org/doc/html/rfc6902) is a way to specify the modifications to perform on a resource. JSON patch uses paths and a limited set of operations to describe how to transform the current state of the resource into a new state. JSON patch documents are always arrays, where each element contains an operation, a path to the field to update, and the new value. For example, in this feature flag representation: ```json { "name": "New recommendations engine", "key": "engine.enable", "description": "This is the description", ... } ``` You can change the feature flag's description with the following patch document: ```json [{ "op": "replace", "path": "/description", "value": "This is the new description" }] ``` You can specify multiple modifications to perform in a single request. You can also test that certain preconditions are met before applying the patch: ```json [ { "op": "test", "path": "/version", "value": 10 }, { "op": "replace", "path": "/description", "value": "The new description" } ] ``` The above patch request tests whether the feature flag's `version` is `10`, and if so, changes the feature flag's description. Attributes that are not editable, such as a resource's `_links`, have names that start with an underscore. ### Updates using JSON merge patch [JSON merge patch](https://datatracker.ietf.org/doc/html/rfc7386) is another format for specifying the modifications to perform on a resource. JSON merge patch is less expressive than JSON patch. However, in many cases it is simpler to construct a merge patch document. For example, you can change a feature flag's description with the following merge patch document: ```json { "description": "New flag description" } ``` ### Updates using semantic patch Some resources support the semantic patch format. A semantic patch is a way to specify the modifications to perform on a resource as a set of executable instructions. Semantic patch allows you to be explicit about intent using precise, custom instructions. In many cases, you can define semantic patch instructions independently of the current state of the resource. This can be useful when defining a change that may be applied at a future date. To make a semantic patch request, you must append `domain-model=launchdarkly.semanticpatch` to your `Content-Type` header. Here's how: ``` Content-Type: application/json; domain-model=launchdarkly.semanticpatch ``` If you call a semantic patch resource without this header, you will receive a `400` response because your semantic patch will be interpreted as a JSON patch. The body of a semantic patch request takes the following properties: * `comment` (string): (Optional) A description of the update. * `environmentKey` (string): (Required for some resources only) The environment key. * `instructions` (array): (Required) A list of actions the update should perform. Each action in the list must be an object with a `kind` property that indicates the instruction. If the instruction requires parameters, you must include those parameters as additional fields in the object. The documentation for each resource that supports semantic patch includes the available instructions and any additional parameters. For example: ```json { "comment": "optional comment", "instructions": [ {"kind": "turnFlagOn"} ] } ``` Semantic patches are not applied partially; either all of the instructions are applied or none of them are. If **any** instruction is invalid, the endpoint returns an error and will not change the resource. If all instructions are valid, the request succeeds and the resources are updated if necessary, or left unchanged if they are already in the state you request. ### Updates with comments You can submit optional comments with `PATCH` changes. To submit a comment along with a JSON patch document, use the following format: ```json { "comment": "This is a comment string", "patch": [{ "op": "replace", "path": "/description", "value": "The new description" }] } ``` To submit a comment along with a JSON merge patch document, use the following format: ```json { "comment": "This is a comment string", "merge": { "description": "New flag description" } } ``` To submit a comment along with a semantic patch, use the following format: ```json { "comment": "This is a comment string", "instructions": [ {"kind": "turnFlagOn"} ] } ``` ## Errors The API always returns errors in a common format. Here's an example: ```json { "code": "invalid_request", "message": "A feature with that key already exists", "id": "30ce6058-87da-11e4-b116-123b93f75cba" } ``` The `code` indicates the general class of error. The `message` is a human-readable explanation of what went wrong. The `id` is a unique identifier. Use it when you're working with LaunchDarkly Support to debug a problem with a specific API call. ### HTTP status error response codes | Code | Definition | Description | Possible Solution | | ---- | ----------------- | ------------------------------------------------------------------------------------------- | ---------------------------------------------------------------- | | 400 | Invalid request | The request cannot be understood. | Ensure JSON syntax in request body is correct. | | 401 | Invalid access token | Requestor is unauthorized or does not have permission for this API call. | Ensure your API access token is valid and has the appropriate permissions. | | 403 | Forbidden | Requestor does not have access to this resource. | Ensure that the account member or access token has proper permissions set. | | 404 | Invalid resource identifier | The requested resource is not valid. | Ensure that the resource is correctly identified by ID or key. | | 405 | Method not allowed | The request method is not allowed on this resource. | Ensure that the HTTP verb is correct. | | 409 | Conflict | The API request can not be completed because it conflicts with a concurrent API request. | Retry your request. | | 422 | Unprocessable entity | The API request can not be completed because the update description can not be understood. | Ensure that the request body is correct for the type of patch you are using, either JSON patch or semantic patch. | 429 | Too many requests | Read [Rate limiting](https://launchdarkly.com/docs/api#rate-limiting). | Wait and try again later. | ## CORS The LaunchDarkly API supports Cross Origin Resource Sharing (CORS) for AJAX requests from any origin. If an `Origin` header is given in a request, it will be echoed as an explicitly allowed origin. Otherwise the request returns a wildcard, `Access-Control-Allow-Origin: *`. For more information on CORS, read the [CORS W3C Recommendation](http://www.w3.org/TR/cors). Example CORS headers might look like: ```http Access-Control-Allow-Headers: Accept, Content-Type, Content-Length, Accept-Encoding, Authorization Access-Control-Allow-Methods: OPTIONS, GET, DELETE, PATCH Access-Control-Allow-Origin: * Access-Control-Max-Age: 300 ``` You can make authenticated CORS calls just as you would make same-origin calls, using either [token or session-based authentication](https://launchdarkly.com/docs/api#authentication). If you are using session authentication, you should set the `withCredentials` property for your `xhr` request to `true`. You should never expose your access tokens to untrusted entities. ## Rate limiting We use several rate limiting strategies to ensure the availability of our APIs. Rate-limited calls to our APIs return a `429` status code. Calls to our APIs include headers indicating the current rate limit status. The specific headers returned depend on the API route being called. The limits differ based on the route, authentication mechanism, and other factors. Routes that are not rate limited may not contain any of the headers described below. > ### Rate limiting and SDKs > > LaunchDarkly SDKs are never rate limited and do not use the API endpoints defined here. LaunchDarkly uses a different set of approaches, including streaming/server-sent events and a global CDN, to ensure availability to the routes used by LaunchDarkly SDKs. ### Global rate limits Authenticated requests are subject to a global limit. This is the maximum number of calls that your account can make to the API per ten seconds. All service and personal access tokens on the account share this limit, so exceeding the limit with one access token will impact other tokens. Calls that are subject to global rate limits may return the headers below: | Header name | Description | | ------------------------------ | -------------------------------------------------------------------------------- | | `X-Ratelimit-Global-Remaining` | The maximum number of requests the account is permitted to make per ten seconds. | | `X-Ratelimit-Reset` | The time at which the current rate limit window resets in epoch milliseconds. | We do not publicly document the specific number of calls that can be made globally. This limit may change, and we encourage clients to program against the specification, relying on the two headers defined above, rather than hardcoding to the current limit. ### Route-level rate limits Some authenticated routes have custom rate limits. These also reset every ten seconds. Any service or personal access tokens hitting the same route share this limit, so exceeding the limit with one access token may impact other tokens. Calls that are subject to route-level rate limits return the headers below: | Header name | Description | | ----------------------------- | ----------------------------------------------------------------------------------------------------- | | `X-Ratelimit-Route-Remaining` | The maximum number of requests to the current route the account is permitted to make per ten seconds. | | `X-Ratelimit-Reset` | The time at which the current rate limit window resets in epoch milliseconds. | A _route_ represents a specific URL pattern and verb. For example, the [Delete environment](https://launchdarkly.com/docs/api/environments/delete-environment) endpoint is considered a single route, and each call to delete an environment counts against your route-level rate limit for that route. We do not publicly document the specific number of calls that an account can make to each endpoint per ten seconds. These limits may change, and we encourage clients to program against the specification, relying on the two headers defined above, rather than hardcoding to the current limits. ### IP-based rate limiting We also employ IP-based rate limiting on some API routes. If you hit an IP-based rate limit, your API response will include a `Retry-After` header indicating how long to wait before re-trying the call. Clients must wait at least `Retry-After` seconds before making additional calls to our API, and should employ jitter and backoff strategies to avoid triggering rate limits again. ## OpenAPI (Swagger) and client libraries We have a [complete OpenAPI (Swagger) specification](https://app.launchdarkly.com/api/v2/openapi.json) for our API. We auto-generate multiple client libraries based on our OpenAPI specification. To learn more, visit the [collection of client libraries on GitHub](https://github.com/search?q=topic%3Alaunchdarkly-api+org%3Alaunchdarkly&type=Repositories). Alternatively, you can use the specification to generate client libraries to interact with our REST API in your language of choice. Or, you can refer to our API endpoints' documentation for guidance on how to make requests with a common HTTP library in your language of choice. Our OpenAPI specification is supported by several API-based tools such as Postman and Insomnia. In many cases, you can directly import our specification to explore our APIs. ## Method overriding Some firewalls and HTTP clients restrict the use of verbs other than `GET` and `POST`. In those environments, our API endpoints that use `DELETE`, `PATCH`, and `PUT` verbs are inaccessible. To avoid this issue, our API supports the `X-HTTP-Method-Override` header, allowing clients to "tunnel" `DELETE`, `PATCH`, and `PUT` requests using a `POST` request. For example, to call a `PATCH` endpoint using a `POST` request, you can include `X-HTTP-Method-Override:PATCH` as a header. ## Beta resources We sometimes release new API resources in **beta** status before we release them with general availability. Resources that are in beta are still undergoing testing and development. They may change without notice, including becoming backwards incompatible. We try to promote resources into general availability as quickly as possible. This happens after sufficient testing and when we're satisfied that we no longer need to make backwards-incompatible changes. We mark beta resources with a "Beta" callout in our documentation, pictured below: > ### This feature is in beta > > To use this feature, pass in a header including the `LD-API-Version` key with value set to `beta`. Use this header with each call. To learn more, read [Beta resources](https://launchdarkly.com/docs/api#beta-resources). > > Resources that are in beta are still undergoing testing and development. They may change without notice, including becoming backwards incompatible. ### Using beta resources To use a beta resource, you must include a header in the request. If you call a beta resource without this header, you receive a `403` response. Use this header: ``` LD-API-Version: beta ``` ## Federal and EU environments In addition to the commercial versions, LaunchDarkly offers instances for federal agencies and those based in the European Union (EU). ### Federal environments The version of LaunchDarkly that is available on domains controlled by the United States government is different from the version of LaunchDarkly available to the general public. If you are an employee or contractor for a United States federal agency and use LaunchDarkly in your work, you likely use the federal instance of LaunchDarkly. If you are working in the federal instance of LaunchDarkly, the base URI for each request is `https://app.launchdarkly.us`.

If you are based in the EU, you likely use the EU instance of LaunchDarkly. The LaunchDarkly EU instance complies with EU data residency principles, including the protection and confidentiality of EU customer information. If you are working in the EU instance of LaunchDarkly, the base URI for each request is `https://app.eu.launchdarkly.com`. To learn more, read [LaunchDarkly in the European Union (EU)](https://launchdarkly.com/docs/home/infrastructure/eu). ## Versioning We try hard to keep our REST API backwards compatible, but we occasionally have to make backwards-incompatible changes in the process of shipping new features. These breaking changes can cause unexpected behavior if you don't prepare for them accordingly. Updates to our REST API include support for the latest features in LaunchDarkly. We also release a new version of our REST API every time we make a breaking change. We provide simultaneous support for multiple API versions so you can migrate from your current API version to a new version at your own pace. ### Setting the API version per request You can set the API version on a specific request by sending an `LD-API-Version` header, as shown in the example below: ``` LD-API-Version: 20240415 ``` The header value is the version number of the API version you would like to request. The number for each version corresponds to the date the version was released in `yyyymmdd` format. In the example above the version `20240415` corresponds to April 15, 2024. ### Setting the API version per access token When you create an access token, you must specify a specific version of the API to use. This ensures that integrations using this token cannot be broken by version changes. Tokens created before versioning was released have their version set to `20160426`, which is the version of the API that existed before the current versioning scheme, so that they continue working the same way they did before versioning. If you would like to upgrade your integration to use a new API version, you can explicitly set the header described above. > ### Best practice: Set the header for every client or integration > > We recommend that you set the API version header explicitly in any client or integration you build. > > Only rely on the access token API version during manual testing. ### API version changelog <table> <tr> <th>Version</th> <th>Changes</th> <th>End of life (EOL)</th> </tr> <tr> <td>`20240415`</td> <td> <ul><li>Changed several endpoints from unpaginated to paginated.

== What's this? {ComicFury}[https://comicfury.com] is an excellent no-bullshit webcomic hosting site created and maintained by the legend Kyo. You should support them on {Patreon}[https://www.patreon.com/comicfury]! {Jekyll}[https://jekyllrb.com] is a highly regarded and widespread static site generator. It builds simple slowly-changing content into HTML files using templates. RageRender allows you to use your ComicFury templates to generate a static version of your webcomic site using Jekyll. You just supply your templates, comics and blogs, and RageRender will output a site that mimics your ComicFury site. Well, I say "mimics". Output is a static site, which means all of the interactive elements of ComicFury don't work. This includes comments, subscriptions, search, and comic management. === But why?! RageRender allows those of us who work on making changes to ComicFury site templates to test our changes before we put them live. With RageRender, you can edit your CSS, HTML templates and site settings before you upload them to ComicFury. This makes the process of testing changes quicker and makes it much more likely that you catch mistakes before any comic readers have a chance to see them. RageRender doesn't compete with the most excellent ComicFury (who's Patreon you should contribute to, as I do!) – you should continue to use ComicFury for all your day-to-day artistic rage management needs. But if you find yourself making changes to a site design, RageRender may be able to help you. == Getting started First, you need to have {Ruby}[https://www.ruby-lang.org/] and {Bundler}[https://bundle.io/] installed. The Jekyll site has {good guides on how to do that}[https://jekyllrb.com/docs/installation/] depending on your operating system. To set up a new site, open a terminal and type: mkdir mycomic && cd mycomic bundle init bundle add jekyll bundle add ragerender --group=jekyll_plugins Now you can add comics! Add the image into an <tt>images</tt> folder: mkdir images cp 'cool comic.jpg' 'images/My first page.jpg' The file name of the image will be the title of your comic page. And that's it, you added your first comic! If you want to add an author note, create a text file in a folder called <tt>_comics</tt> that has the same file name, but with a <tt>.txt</tt> extension: mkdir _comics echo "Check out my cool comic y'all!" > '_comics/My first page.txt' Or use HTML: echo "This is my <strong>first</strong> page!" > '_comics/My first page.html' Generate the site using: bundle exec jekyll build Or start a local website to see it in your browser: bundle exec jekyll serve # Now visit http://localhost:4000! === Customising your site You'll notice a few things that might be off about your site, including that the webcomic title and author name are probably not what you were expecting. You can create a configuration file to tell RageRender the important details. Put something like this in your webcomic folder and call it <tt>_config.yml</tt>: title: "My awesome webcomic!" slogan: "It's the best!" description: > My epic story about how him and her fell into a romantic polycule with they and them status: active genres: - Comedy - Romance defaults: - scope: path: '' values: author: "John smith" theme: ragerender Your webcomic now has its basic information set up. === Adding your layouts If you want to use your own layout code, then create a <tt>_layouts</tt> directory and put the contents of each of your ComicFury layout tabs in there, and then put your CSS in the main folder. The easiest way is to go to your Webcomic Management, click "Edit Layout", then in the box labelled "Useful", click "Download Layout Backup". Pass this file to RageRender, which will <tt>unpack</tt> it for you: bundle exec jekyll unpack mycomic-2025-09-13.cflxml You should end up with a full set of files like: _layouts archive.html blog-archive.html blog-display.html comic-page.html error-page.html overall.html overview.html search.html layout.css Now when you build your site, your custom templates and styles will be used instead. === Adding blogs Add your blogs into a folder called <tt>_posts</tt>: cat _posts/2025-05-29-my-new-comic.md Hey guys, welcome to my new comic! It's gonna be so sick! Note that the name of your blog post has to include the date and the title, or it'll be ignored. === Customising comics and blogs You can add {Front Matter}[https://jekyllrb.com/docs/front-matter/] to set the details of your author notes and blogs manually: --- title: "spooky comic page" date: "2025-03-05 16:20" image: "images/ghost.png" author: "Jane doe" description: "Some spooky mouseover text" keywords: [excellent, comic page, spooky] custom: # use yes and no for tickbox settings spooky: yes # use text in quotes for short texts mantra: "live long and prosper" # use indented text for long texts haiku: > Testing webcomics Now easier than ever Thanks to RageRender transcript: > The transcript contains a machine-readable version of all the text in your comic image. comments: - author: "Skippy" date: "13 Mar 2025, 3.45 PM" comment: "Wow this is so sick!" --- Your author note still goes at the end, like this! === Adding extra pages You can add extra pages just by adding new HTML files to your webcomic folder. The name of the file becomes the URL that it will use. Pages by default won't be embedded into your 'Overall' layout. You can change that and more with optional Front Matter: --- # Include this line to set the page title title: "Bonus content" # Include this line to hide the page from the navigation menu hidden: yes # Include this line to embed this page in the overall layout layout: Overall --- <h1>yo check out my bonus content!</h1> === Controlling the front page As on ComicFury you have a few options for setting the front page of you site. You control this by setting a <tt>frontpage</tt> key in your site config. - <tt>latest</tt> will display the latest comic (also the default) - <tt>first</tt> will display the first comic - <tt>chapter</tt> will display the first comic in the latest chapter - <tt>blog</tt> will display the list of blog posts - <tt>archive</tt> will display the comic archive - <tt>overview</tt> will display the comic overview (blogs and latest page) - anything else will display the extra page that has the matching <tt>slug</tt> in its Front Matter === Comics with custom HTML code You can use custom HTML code in place of an image for your comic page. Instead of creating an image, just create an HTML file in your <tt>images</tt> folder: cat '<video src="/files/my-animation.webm"></video>" > images/1.html === Multi-image comics You can add up to 12 images to each comic page on ComicFury. To do that in RageRender, add each image to an <tt>images</tt> key in your comic page: --- title: "Comic with many pages" date: "2026-04-20 16:20" images: - /images/first.png - /images/second.png - /images/third.png --- === Testing search pages Live search does not work in RageRender, as your site is statically built and can't respond to new data from the browser. However, you can simulate a search when you build the site to help test search results designs. To do that, add a `searchterm` to the search page using defaults in your `_config.yml`: defaults: - scope: path: '' layout: search values: searchterm: "my character" The search that gets performed will be somewhat similar to how ComicFury will search your comic, but may not be exactly the same. === Putting changes on ComicFury Once you're done making changes, you can <tt>pack</tt> your layout: bundle exec jekyll pack The resulting file can be uploaded to ComicFury by going to your Webcomic Management, clicking "Edit Layout", then in the box labelled "Useful", click "Restore Layout Backup". === Stuff that doesn't work Here is a probably incomplete list of things you can expect to be different about your local site compared to ComicFury: - Any comments you specify in Front Matter will be present, but you can't add new ones - Search doesn't do anything at all - Saving and loading your place in the comic isn't implemented - GET and POST variables in templates are ignored and will always be blank - Random numbers in templates will be random only once per site build, not once per page call == Without Jekyll RageRender can also be used without Jekyll to turn ComicFury templates into templates in other languages. E.g: gem install ragerender echo "[c:iscomicpage]<div>[f:js|v:comictitle]</div>[/]" > template.html ruby $(gem which ragerender/to_liquid) template.html # {% if iscomicpage %}<div>{{ comictitle | escape }}</div>{% endif %} ruby $(gem which ragerender/to_erb) template.html # <% if iscomicpage %><div><%= js(comictitle) %></div><% end %> You still need to pass the correct variables to these templates; browse {this unofficial documentation}[https://github.com/heyeinin/comicfury-documentation] or RageRender::ComicDrop etc. to see which variables work on which templates. == Get help That's not a proclamation but an invitation! Reach out if you're having trouble by {raising an issue}[https://github.com/simonwo/ragerender/issues] or posting in the ComicFury forums.
