Dnsclay implements a DNS server that translates DNS UPDATE (RFC 2136) and DNS AXFR (RFC 5936, zone transfers) requests to the many custom cloud DNS operator APIs for managing DNS records/zones. Dnsclay keeps a local copy of the records, periodically synchronizes its copy with authoritative data at the cloud DNS operator, and sends DNS NOTIFY (RFC 1996) messages to configured listeners when any records changed. Dnsclay also has a web interface for managing the configured zones, and for viewing and editing records. Most cloud DNS operators implement their own custom APIs for changing DNS records. Application developers are tempted to add support for long lists of those custom APIs to their applications so they can make automated DNS changes (even just for handling ACME verification through DNS). This is time-consuming and error-prone. Developers can instead settle on the standard DNS interfaces with UPDATE/AXFR/NOTIFY, talking either directly to DNS servers that implement them (like BIND, Knot), or talking to dnsclay which does the translating. Dnsclay implements TLS with the option for client certificate authentication (mutual TLS) based on public keys (ignoring certificate name/expiration/constraints, keeping it simple). DNS TSIG (RFC 8945) is also supported. Dnsclay helps diagnosing errors by returning error responses with Extended DNS Errors (RFC 8914) to requests with EDNS0. Dnsclay does not answer regular DNS queries for records (recursive or authoritative), with the exception of giving authoritative answers to SOA queries. Clients can use this to check if the zone has been updated before deciding to do an AXFR of the full zone. One of the implemented backend providers, "rfc2136", connects to DNS servers implementing the standard DNS UPDATE/AXFR protocols, making dnsclay a web-based zone editor for standard DNS servers. Like secondary DNS servers, dnsclay periodically fetches the SOA record from authoritative name servers, and does an AXFR if the zone serial changes. Dnsclay also periodically does a full sync regardless of SOA serial, since some DNS operators don't change the serial when a zone changes. In such cases, dnsclay will keep track of its own serial, so its clients can properly detect zone changes. The "refresh interval" from the SOA record is not used, since it is often configured to work only with the setup of the primary/secondary servers of the DNS operator. After a change to a zone, either because of DNS UPDATE through dnsclay or by dnsclay detecting a record change at the DNS operator, dnsclay will temporarily increase the interval with which it checks again for a new update, speculating more changes are coming. Timely notification of DNS record changes is useful during lock-step changes like key rollovers. Cloud DNS operators typically don't have a mechanism to notify applications of changes to records. DNS UPDATE/AXFR/NOTIFY may look relatively complicated to application developers interested in making automated DNS changes. They may be expecting a HTTP/JSON API. If one is standardized, dnsclay could implement it. Changes in a DNS UPDATE request must be applied atomically: Either all the changes in a request must be applied, or none. Dnsclay cannot implement this requirement for all requests. With the libdns API, records cannot be added and removed atomically. Cloud DNS operators may have unexpected limitations. If standard DNS resource record types are not implemented, adding them may result in an error. The dnsclay server does not process multiple messages on a single TCP connection in parallel. It reads a request, process it, and writes a response, then starts on the next request. Multiple connections, and UDP packets, are handled in parallel. The following providers are implemented in dnsclay, with community-provided implementations maintained at https://github.com/libdns:

Pact Go enables consumer driven contract testing, providing a mock service and DSL for the consumer project, and interaction playback and verification for the service provider project. Consumer side Pact testing is an isolated test that ensures a given component is able to collaborate with another (remote) component. Pact will automatically start a Mock server in the background that will act as the collaborators' test double. This implies that any interactions expected on the Mock server will be validated, meaning a test will fail if all interactions were not completed, or if unexpected interactions were found: A typical consumer-side test would look something like this: If this test completed successfully, a Pact file should have been written to ./pacts/my_consumer-my_provider.json containing all of the interactions expected to occur between the Consumer and Provider. In addition to verbatim value matching, you have 3 useful matching functions in the `dsl` package that can increase expressiveness and reduce brittle test cases. Here is a complex example that shows how all 3 terms can be used together: This example will result in a response body from the mock server that looks like: See the examples in the dsl package and the matcher tests (https://github.com/pact-foundation/pact-go/blob/master/dsl/matcher_test.go) for more matching examples. NOTE: You will need to use valid Ruby regular expressions (http://ruby-doc.org/core-2.1.5/Regexp.html) and double escape backslashes. Read more about flexible matching (https://github.com/realestate-com-au/pact/wiki/Regular-expressions-and-type-matching-with-Pact. Provider side Pact testing, involves verifying that the contract - the Pact file - can be satisfied by the Provider. A typical Provider side test would like something like: Note that `PactURLs` can be a list of local pact files or remote based urls (possibly from a Pact Broker - http://docs.pact.io/documentation/sharings_pacts.html). Pact reads the specified pact files (from remote or local sources) and replays the interactions against a running Provider. If all of the interactions are met we can say that both sides of the contract are satisfied and the test passes. When validating a Provider, you have 3 options to provide the Pact files: 1. Use "PactURLs" to specify the exact set of pacts to be replayed: 2. Use "PactBroker" to automatically find all of the latest consumers: 3. Use "PactBroker" and "Tags" to automatically find all of the latest consumers: Options 2 and 3 are particularly useful when you want to validate that your Provider is able to meet the contracts of what's in Production and also the latest in development. See this [article](http://rea.tech/enter-the-pact-matrix-or-how-to-decouple-the-release-cycles-of-your-microservices/) for more on this strategy. Each interaction in a pact should be verified in isolation, with no context maintained from the previous interactions. So how do you test a request that requires data to exist on the provider? Provider states are how you achieve this using Pact. Provider states also allow the consumer to make the same request with different expected responses (e.g. different response codes, or the same resource with a different subset of data). States are configured on the consumer side when you issue a dsl.Given() clause with a corresponding request/response pair. Configuring the provider is a little more involved, and (currently) requires 2 running API endpoints to retrieve and configure available states during the verification process. The two options you must provide to the dsl.VerifyRequest are: Example routes using the standard Go http package might look like this, note the `/states` endpoint returns a list of available states for each known consumer: See the examples or read more at http://docs.pact.io/documentation/provider_states.html. See the Pact Broker (http://docs.pact.io/documentation/sharings_pacts.html) documentation for more details on the Broker and this article (http://rea.tech/enter-the-pact-matrix-or-how-to-decouple-the-release-cycles-of-your-microservices/) on how to make it work for you. Publishing using Go code: Publishing from the CLI: Use a cURL request like the following to PUT the pact to the right location, specifying your consumer name, provider name and consumer version. The following flags are required to use basic authentication when publishing or retrieving Pact files to/from a Pact Broker: Pact Go uses a simple log utility (logutils - https://github.com/hashicorp/logutils) to filter log messages. The CLI already contains flags to manage this, should you want to control log level in your tests, you can set it like so:

Package coldbrew provides input management functionality for various input devices. Package coldbrew provides a game client and scene management system for the Bappa Framework. Coldbrew handles game lifecycle, rendering, input processing, scene transitions, and resource management. It serves as the top-level interface for game developers, coordinating between the various components of the Bappa ecosystem.

Coldbrew is built on top of the Ebiten game engine (https://github.com/hajimehoshi/ebiten), which provides the low-level graphics rendering, input detection, and cross-platform functionality. Coldbrew extends Ebiten with a comprehensive entity-component system and game management features while integrating the other components of the Bappa Framework: Blueprint, Warehouse, Tteokbokki, and Mask.

The primary aim of this file is to re-export all structs, constants, and functions from the ibapi package, allowing developers to access them through a single cohesive package. This simplifies the process of integrating with the Interactive Brokers API by reducing the need to manage multiple imports and providing a more straightforward API surface for developers.

Package systemd package provides various data structures that marshal and unmarshal systemd-specific INI configuration(s). The systemd package also allows for marshalling and unmarshalling into various other types of data formats such as json, yaml, ini, and systemd. A systemd service file is used to describe how a service (a process or a set of processes) should be started and managed by systemd, the system and service manager for Linux operating systems. While systemd units can be of various types, including service, socket, device, mount, automount, swap, target, path, timer, slice, and scope units, the specific requirements can vary based on the type of unit. However, I'll focus on the typical and most commonly used unit type: the service unit file. In practice, while you can technically create a service with even less information (you could skip the Install section if you never want the service to start automatically at boot), it's recommended to at least specify these basic sections and fields to ensure clarity, functionality, and integration with the system's boot process. Additional fields and sections can be added based on the specific needs and dependencies of your service.

Package iam provides the client and types for making API requests to AWS Identity and Access Management. AWS Identity and Access Management (IAM) is a web service that you can use to manage users and user permissions under your AWS account. This guide provides descriptions of IAM actions that you can call programmatically. For general information about IAM, see AWS Identity and Access Management (IAM) (http://aws.amazon.com/iam/). For the user guide for IAM, see Using IAM (http://docs.aws.amazon.com/IAM/latest/UserGuide/). AWS provides SDKs that consist of libraries and sample code for various programming languages and platforms (Java, Ruby, .NET, iOS, Android, etc.). The SDKs provide a convenient way to create programmatic access to IAM and AWS. For example, the SDKs take care of tasks such as cryptographically signing requests (see below), managing errors, and retrying requests automatically. For information about the AWS SDKs, including how to download and install them, see the Tools for Amazon Web Services (http://aws.amazon.com/tools/) page. We recommend that you use the AWS SDKs to make programmatic API calls to IAM. However, you can also use the IAM Query API to make direct calls to the IAM web service. To learn more about the IAM Query API, see Making Query Requests (http://docs.aws.amazon.com/IAM/latest/UserGuide/IAM_UsingQueryAPI.html) in the Using IAM guide. IAM supports GET and POST requests for all actions. That is, the API does not require you to use GET for some actions and POST for others. However, GET requests are subject to the limitation size of a URL. Therefore, for operations that require larger sizes, use a POST request. Requests must be signed using an access key ID and a secret access key. We strongly recommend that you do not use your AWS account access key ID and secret access key for everyday work with IAM. You can use the access key ID and secret access key for an IAM user or you can use the AWS Security Token Service to generate temporary security credentials and use those to sign requests. To sign requests, we recommend that you use Signature Version 4 (http://docs.aws.amazon.com/general/latest/gr/signature-version-4.html). If you have an existing application that uses Signature Version 2, you do not have to update it to use Signature Version 4. However, some operations now require Signature Version 4. The documentation for operations that require version 4 indicate this requirement. For more information, see the following: AWS Security Credentials (http://docs.aws.amazon.com/general/latest/gr/aws-security-credentials.html). This topic provides general information about the types of credentials used for accessing AWS. IAM Best Practices (http://docs.aws.amazon.com/IAM/latest/UserGuide/IAMBestPractices.html). This topic presents a list of suggestions for using the IAM service to help secure your AWS resources. Signing AWS API Requests (http://docs.aws.amazon.com/general/latest/gr/signing_aws_api_requests.html). This set of topics walk you through the process of signing a request using an access key ID and secret access key. See https://docs.aws.amazon.com/goto/WebAPI/iam-2010-05-08 for more information on this service. See iam package documentation for more information. https://docs.aws.amazon.com/sdk-for-go/api/service/iam/ To AWS Identity and Access Management with the SDK use the New function to create a new service client. With that client you can make API requests to the service. These clients are safe to use concurrently. See the SDK's documentation for more information on how to use the SDK. https://docs.aws.amazon.com/sdk-for-go/api/ See aws.Config documentation for more information on configuring SDK clients. https://docs.aws.amazon.com/sdk-for-go/api/aws/#Config See the AWS Identity and Access Management client IAM for more information on creating client for this service. https://docs.aws.amazon.com/sdk-for-go/api/service/iam/#New

Package cadence and its subdirectories contain the Cadence client side framework. The Cadence service is a task orchestrator for your application’s tasks. Applications using Cadence can execute a logical flow of tasks, especially long-running business logic, asynchronously or synchronously. They can also scale at runtime on distributed systems. A quick example illustrates its use case. Consider Uber Eats where Cadence manages the entire business flow from placing an order, accepting it, handling shopping cart processes (adding, updating, and calculating cart items), entering the order in a pipeline (for preparing food and coordinating delivery), to scheduling delivery as well as handling payments. Cadence consists of a programming framework (or client library) and a managed service (or backend). The framework enables developers to author and coordinate tasks in Go code. The root cadence package contains common data structures. The subpackages are: The Cadence hosted service brokers and persists events generated during workflow execution. Worker nodes owned and operated by customers execute the coordination and task logic. To facilitate the implementation of worker nodes Cadence provides a client-side library for the Go language. In Cadence, you can code the logical flow of events separately as a workflow and code business logic as activities. The workflow identifies the activities and sequences them, while an activity executes the logic. Dynamic workflow execution graphs - Determine the workflow execution graphs at runtime based on the data you are processing. Cadence does not pre-compute the execution graphs at compile time or at workflow start time. Therefore, you have the ability to write workflows that can dynamically adjust to the amount of data they are processing. If you need to trigger 10 instances of an activity to efficiently process all the data in one run, but only 3 for a subsequent run, you can do that. Child Workflows - Orchestrate the execution of a workflow from within another workflow. Cadence will return the results of the child workflow execution to the parent workflow upon completion of the child workflow. No polling is required in the parent workflow to monitor status of the child workflow, making the process efficient and fault tolerant. Durable Timers - Implement delayed execution of tasks in your workflows that are robust to worker failures. Cadence provides two easy to use APIs, **workflow.Sleep** and **workflow.Timer**, for implementing time based events in your workflows. Cadence ensures that the timer settings are persisted and the events are generated even if workers executing the workflow crash. Signals - Modify/influence the execution path of a running workflow by pushing additional data directly to the workflow using a signal. Via the Signal facility, Cadence provides a mechanism to consume external events directly in workflow code. Task routing - Efficiently process large amounts of data using a Cadence workflow, by caching the data locally on a worker and executing all activities meant to process that data on that same worker. Cadence enables you to choose the worker you want to execute a certain activity by scheduling that activity execution in the worker's specific task-list. Unique workflow ID enforcement - Use business entity IDs for your workflows and let Cadence ensure that only one workflow is running for a particular entity at a time. Cadence implements an atomic "uniqueness check" and ensures that no race conditions are possible that would result in multiple workflow executions for the same workflow ID. Therefore, you can implement your code to attempt to start a workflow without checking if the ID is already in use, even in the cases where only one active execution per workflow ID is desired. Perpetual/ContinueAsNew workflows - Run periodic tasks as a single perpetually running workflow. With the "ContinueAsNew" facility, Cadence allows you to leverage the "unique workflow ID enforcement" feature for periodic workflows. Cadence will complete the current execution and start the new execution atomically, ensuring you get to keep your workflow ID. By starting a new execution Cadence also ensures that workflow execution history does not grow indefinitely for perpetual workflows. At-most once activity execution - Execute non-idempotent activities as part of your workflows. Cadence will not automatically retry activities on failure. For every activity execution Cadence will return a success result, a failure result, or a timeout to the workflow code and let the workflow code determine how each one of those result types should be handled. Asynch Activity Completion - Incorporate human input or thrid-party service asynchronous callbacks into your workflows. Cadence allows a workflow to pause execution on an activity and wait for an external actor to resume it with a callback. During this pause the activity does not have any actively executing code, such as a polling loop, and is merely an entry in the Cadence datastore. Therefore, the workflow is unaffected by any worker failures happening over the duration of the pause. Activity Heartbeating - Detect unexpected failures/crashes and track progress in long running activities early. By configuring your activity to report progress periodically to the Cadence server, you can detect a crash that occurs 10 minutes into an hour-long activity execution much sooner, instead of waiting for the 60-minute execution timeout. The recorded progress before the crash gives you sufficient information to determine whether to restart the activity from the beginning or resume it from the point of failure. Timeouts for activities and workflow executions - Protect against stuck and unresponsive activities and workflows with appropriate timeout values. Cadence requires that timeout values are provided for every activity or workflow invocation. There is no upper bound on the timeout values, so you can set timeouts that span days, weeks, or even months. Visibility - Get a list of all your active and/or completed workflow. Explore the execution history of a particular workflow execution. Cadence provides a set of visibility APIs that allow you, the workflow owner, to monitor past and current workflow executions. Debuggability - Replay any workflow execution history locally under a debugger. The Cadence client library provides an API to allow you to capture a stack trace from any failed workflow execution history.

Package nakadi is a client library for the Nakadi event broker. It provides convenient access to many features of Nakadi's API. The package can be used to manage event type definitions. The EventAPI can be used to inspect existing event types and allows further to create new event types and to update existing ones. The SubscriptionAPI provides subscription management: existing subscriptions can be fetched from Nakadi and of course it is also possible to create new ones. The PublishAPI of this package is used to broadcast event types of all event type categories via Nakadi. Last but not least, the package also implements a StreamAPI, which enables event processing on top of Nakadi's subscription based high level API. To make the communication with Nakadi more resilient all sub APIs of this package can be configured to retry failed requests using an exponential back-off algorithm.

Package iris provides a beautifully expressive and easy to use foundation for your next website, API, or distributed app. Source code and other details for the project are available at GitHub: 11.1.1 The only requirement is the Go Programming Language, at least version 1.8 but 1.11.1 and above is highly recommended. Example code: You can start the server(s) listening to any type of `net.Listener` or even `http.Server` instance. The method for initialization of the server should be passed at the end, via `Run` function. Below you'll see some useful examples: UNIX and BSD hosts can take advantage of the reuse port feature. Example code: That's all with listening, you have the full control when you need it. Let's continue by learning how to catch CONTROL+C/COMMAND+C or unix kill command and shutdown the server gracefully. In order to manually manage what to do when app is interrupted, we have to disable the default behavior with the option `WithoutInterruptHandler` and register a new interrupt handler (globally, across all possible hosts). Example code: Access to all hosts that serve your application can be provided by the `Application#Hosts` field, after the `Run` method. But the most common scenario is that you may need access to the host before the `Run` method, there are two ways of gain access to the host supervisor, read below. First way is to use the `app.NewHost` to create a new host and use one of its `Serve` or `Listen` functions to start the application via the `iris#Raw` Runner. Note that this way needs an extra import of the `net/http` package. Example Code: Second, and probably easier way is to use the `host.Configurator`. Note that this method requires an extra import statement of "github.com/kataras/iris/core/host" when using go < 1.9, if you're targeting on go1.9 then you can use the `iris#Supervisor` and omit the extra host import. All common `Runners` we saw earlier (`iris#Addr, iris#Listener, iris#Server, iris#TLS, iris#AutoTLS`) accept a variadic argument of `host.Configurator`, there are just `func(*host.Supervisor)`. Therefore the `Application` gives you the rights to modify the auto-created host supervisor through these. Example Code: Read more about listening and gracefully shutdown by navigating to: All HTTP methods are supported, developers can also register handlers for same paths for different methods. The first parameter is the HTTP Method, second parameter is the request path of the route, third variadic parameter should contains one or more iris.Handler executed by the registered order when a user requests for that specific resouce path from the server. Example code: In order to make things easier for the user, iris provides functions for all HTTP Methods. The first parameter is the request path of the route, second variadic parameter should contains one or more iris.Handler executed by the registered order when a user requests for that specific resouce path from the server. Example code: A set of routes that are being groupped by path prefix can (optionally) share the same middleware handlers and template layout. A group can have a nested group too. `.Party` is being used to group routes, developers can declare an unlimited number of (nested) groups. Example code: iris developers are able to register their own handlers for http statuses like 404 not found, 500 internal server error and so on. Example code: With the help of iris's expressionist router you can build any form of API you desire, with safety. Example code: At the previous example, we've seen static routes, group of routes, subdomains, wildcard subdomains, a small example of parameterized path with a single known parameter and custom http errors, now it's time to see wildcard parameters and macros. iris, like net/http std package registers route's handlers by a Handler, the iris' type of handler is just a func(ctx iris.Context) where context comes from github.com/kataras/iris/context. Iris has the easiest and the most powerful routing process you have ever meet. At the same time, iris has its own interpeter(yes like a programming language) for route's path syntax and their dynamic path parameters parsing and evaluation, We call them "macros" for shortcut. How? It calculates its needs and if not any special regexp needed then it just registers the route with the low-level path syntax, otherwise it pre-compiles the regexp and adds the necessary middleware(s). Standard macro types for parameters: if type is missing then parameter's type is defaulted to string, so {param} == {param:string}. If a function not found on that type then the "string"'s types functions are being used. i.e: Besides the fact that iris provides the basic types and some default "macro funcs" you are able to register your own too!. Register a named path parameter function: at the func(argument ...) you can have any standard type, it will be validated before the server starts so don't care about performance here, the only thing it runs at serve time is the returning func(paramValue string) bool. Example Code: Last, do not confuse ctx.Values() with ctx.Params(). Path parameter's values goes to ctx.Params() and context's local storage that can be used to communicate between handlers and middleware(s) goes to ctx.Values(), path parameters and the rest of any custom values are separated for your own good. Run Static Files Example code: More examples can be found here: https://github.com/kataras/iris/tree/master/_examples/beginner/file-server Middleware is just a concept of ordered chain of handlers. Middleware can be registered globally, per-party, per-subdomain and per-route. Example code: iris is able to wrap and convert any external, third-party Handler you used to use to your web application. Let's convert the https://github.com/rs/cors net/http external middleware which returns a `next form` handler. Example code: Iris supports 5 template engines out-of-the-box, developers can still use any external golang template engine, as `context/context#ResponseWriter()` is an `io.Writer`. All of these five template engines have common features with common API, like Layout, Template Funcs, Party-specific layout, partial rendering and more. Example code: View engine supports bundled(https://github.com/shuLhan/go-bindata) template files too. go-bindata gives you two functions, asset and assetNames, these can be setted to each of the template engines using the `.Binary` func. Example code: A real example can be found here: https://github.com/kataras/iris/tree/master/_examples/view/embedding-templates-into-app. Enable auto-reloading of templates on each request. Useful while developers are in dev mode as they no neeed to restart their app on every template edit. Example code: Note: In case you're wondering, the code behind the view engines derives from the "github.com/kataras/iris/view" package, access to the engines' variables can be granded by "github.com/kataras/iris" package too. Each one of these template engines has different options located here: https://github.com/kataras/iris/tree/master/view . This example will show how to store and access data from a session. You don’t need any third-party library, but If you want you can use any session manager compatible or not. In this example we will only allow authenticated users to view our secret message on the /secret page. To get access to it, the will first have to visit /login to get a valid session cookie, which logs him in. Additionally he can visit /logout to revoke his access to our secret message. Example code: Running the example: Sessions persistence can be achieved using one (or more) `sessiondb`. Example Code: More examples: In this example we will create a small chat between web sockets via browser. Example Server Code: Example Client(javascript) Code: Running the example: Iris has first-class support for the MVC pattern, you'll not find these stuff anywhere else in the Go world. Example Code: // GetUserBy serves // Method: GET // Resource: http://localhost:8080/user/{username:string} // By is a reserved "keyword" to tell the framework that you're going to // bind path parameters in the function's input arguments, and it also // helps to have "Get" and "GetBy" in the same controller. // // func (c *ExampleController) GetUserBy(username string) mvc.Result { // return mvc.View{ // Name: "user/username.html", // Data: username, // } // } Can use more than one, the factory will make sure that the correct http methods are being registered for each route for this controller, uncomment these if you want: Iris web framework supports Request data, Models, Persistence Data and Binding with the fastest possible execution. Characteristics: All HTTP Methods are supported, for example if want to serve `GET` then the controller should have a function named `Get()`, you can define more than one method function to serve in the same Controller. Register custom controller's struct's methods as handlers with custom paths(even with regex parametermized path) via the `BeforeActivation` custom event callback, per-controller. Example: Persistence data inside your Controller struct (share data between requests) by defining services to the Dependencies or have a `Singleton` controller scope. Share the dependencies between controllers or register them on a parent MVC Application, and ability to modify dependencies per-controller on the `BeforeActivation` optional event callback inside a Controller, i.e Access to the `Context` as a controller's field(no manual binding is neede) i.e `Ctx iris.Context` or via a method's input argument, i.e Models inside your Controller struct (set-ed at the Method function and rendered by the View). You can return models from a controller's method or set a field in the request lifecycle and return that field to another method, in the same request lifecycle. Flow as you used to, mvc application has its own `Router` which is a type of `iris/router.Party`, the standard iris api. `Controllers` can be registered to any `Party`, including Subdomains, the Party's begin and done handlers work as expected. Optional `BeginRequest(ctx)` function to perform any initialization before the method execution, useful to call middlewares or when many methods use the same collection of data. Optional `EndRequest(ctx)` function to perform any finalization after any method executed. Session dynamic dependency via manager's `Start` to the MVC Application, i.e Inheritance, recursively. Access to the dynamic path parameters via the controller's methods' input arguments, no binding is needed. When you use the Iris' default syntax to parse handlers from a controller, you need to suffix the methods with the `By` word, uppercase is a new sub path. Example: Register one or more relative paths and able to get path parameters, i.e Response via output arguments, optionally, i.e Where `any` means everything, from custom structs to standard language's types-. `Result` is an interface which contains only that function: Dispatch(ctx iris.Context) and Get where HTTP Method function(Post, Put, Delete...). Iris has a very powerful and blazing fast MVC support, you can return any value of any type from a method function and it will be sent to the client as expected. * if `string` then it's the body. * if `string` is the second output argument then it's the content type. * if `int` then it's the status code. * if `bool` is false then it throws 404 not found http error by skipping everything else. * if `error` and not nil then (any type) response will be omitted and error's text with a 400 bad request will be rendered instead. * if `(int, error)` and error is not nil then the response result will be the error's text with the status code as `int`. * if `custom struct` or `interface{}` or `slice` or `map` then it will be rendered as json, unless a `string` content type is following. * if `mvc.Result` then it executes its `Dispatch` function, so good design patters can be used to split the model's logic where needed. Examples with good patterns to follow but not intend to be used in production of course can be found at: https://github.com/kataras/iris/tree/master/_examples/#mvc. By creating components that are independent of one another, developers are able to reuse components quickly and easily in other applications. The same (or similar) view for one application can be refactored for another application with different data because the view is simply handling how the data is being displayed to the user. If you're new to back-end web development read about the MVC architectural pattern first, a good start is that wikipedia article: https://en.wikipedia.org/wiki/Model%E2%80%93view%E2%80%93controller. But you should have a basic idea of the framework by now, we just scratched the surface.

Package iris provides a beautifully expressive and easy to use foundation for your next website, API, or distributed app. Source code and other details for the project are available at GitHub: 8.5.9 Final The only requirement is the Go Programming Language, at least version 1.8 but 1.9 is highly recommended. Iris takes advantage of the vendor directory feature wisely: https://docs.google.com/document/d/1Bz5-UB7g2uPBdOx-rw5t9MxJwkfpx90cqG9AFL0JAYo. You get truly reproducible builds, as this method guards against upstream renames and deletes. A simple copy-paste and `go get ./...` to resolve two dependencies: https://github.com/kataras/golog and the https://github.com/iris-contrib/httpexpect will work for ever even for older versions, the newest version can be retrieved by `go get` but this file contains documentation for an older version of Iris. Follow the instructions below: 1. install the Go Programming Language: https://golang.org/dl 2. clear yours previously `$GOPATH/src/github.com/kataras/iris` folder or create new 3. download the Iris v8.5.9 (final): https://github.com/kataras/iris/archive/v8.zip 4. extract the contents of the `iris-v8` folder that's inside the downloaded zip file to your `$GOPATH/src/github.com/kataras/iris` 5. navigate to your `$GOPATH/src/github.com/kataras/iris` folder if you're not already there and open a terminal/command prompt, execute the command: `go get ./...` and you're ready to GO:) Example code: You can start the server(s) listening to any type of `net.Listener` or even `http.Server` instance. The method for initialization of the server should be passed at the end, via `Run` function. Below you'll see some useful examples: UNIX and BSD hosts can take advandage of the reuse port feature. Example code: That's all with listening, you have the full control when you need it. Let's continue by learning how to catch CONTROL+C/COMMAND+C or unix kill command and shutdown the server gracefully. In order to manually manage what to do when app is interrupted, we have to disable the default behavior with the option `WithoutInterruptHandler` and register a new interrupt handler (globally, across all possible hosts). Example code: Access to all hosts that serve your application can be provided by the `Application#Hosts` field, after the `Run` method. But the most common scenario is that you may need access to the host before the `Run` method, there are two ways of gain access to the host supervisor, read below. First way is to use the `app.NewHost` to create a new host and use one of its `Serve` or `Listen` functions to start the application via the `iris#Raw` Runner. Note that this way needs an extra import of the `net/http` package. Example Code: Second, and probably easier way is to use the `host.Configurator`. Note that this method requires an extra import statement of "github.com/kataras/iris/core/host" when using go < 1.9, if you're targeting on go1.9 then you can use the `iris#Supervisor` and omit the extra host import. All common `Runners` we saw earlier (`iris#Addr, iris#Listener, iris#Server, iris#TLS, iris#AutoTLS`) accept a variadic argument of `host.Configurator`, there are just `func(*host.Supervisor)`. Therefore the `Application` gives you the rights to modify the auto-created host supervisor through these. Example Code: Read more about listening and gracefully shutdown by navigating to: All HTTP methods are supported, developers can also register handlers for same paths for different methods. The first parameter is the HTTP Method, second parameter is the request path of the route, third variadic parameter should contains one or more iris.Handler executed by the registered order when a user requests for that specific resouce path from the server. Example code: In order to make things easier for the user, iris provides functions for all HTTP Methods. The first parameter is the request path of the route, second variadic parameter should contains one or more iris.Handler executed by the registered order when a user requests for that specific resouce path from the server. Example code: A set of routes that are being groupped by path prefix can (optionally) share the same middleware handlers and template layout. A group can have a nested group too. `.Party` is being used to group routes, developers can declare an unlimited number of (nested) groups. Example code: iris developers are able to register their own handlers for http statuses like 404 not found, 500 internal server error and so on. Example code: With the help of iris's expressionist router you can build any form of API you desire, with safety. Example code: Iris has first-class support for the MVC pattern, you'll not find these stuff anywhere else in the Go world.

Characteristics: All HTTP Methods are supported, for example if want to serve `GET` then the controller should have a function named `Get()`, you can define more than one method function to serve in the same Controller struct. Persistence data inside your Controller struct (share data between requests) via `iris:"persistence"` tag right to the field or Bind using `app.Controller("/" , new(myController), theBindValue)`. Models inside your Controller struct (set-ed at the Method function and rendered by the View) via `iris:"model"` tag right to the field, i.e User UserModel `iris:"model" name:"user"` view will recognise it as `{{.user}}`. If `name` tag is missing then it takes the field's name, in this case the `"User"`. Access to the request path and its parameters via the `Path and Params` fields. Access to the template file that should be rendered via the `Tmpl` field. Access to the template data that should be rendered inside the template file via `Data` field. Access to the template layout via the `Layout` field. Access to the low-level `iris.Context` via the `Ctx` field. Get the relative request path by using the controller's name via `RelPath()`. Get the relative template path directory by using the controller's name via `RelTmpl()`. Flow as you used to, `Controllers` can be registered to any `Party`, including Subdomains, the Party's begin and done handlers work as expected. Optional `BeginRequest(ctx)` function to perform any initialization before the method execution, useful to call middlewares or when many methods use the same collection of data. Optional `EndRequest(ctx)` function to perform any finalization after any method executed. Inheritance, recursively, see for example our `mvc.SessionController/iris.SessionController`, it has the `mvc.Controller/iris.Controller` as an embedded field and it adds its logic to its `BeginRequest`. Source file: https://github.com/kataras/iris/blob/v8/mvc/session_controller.go. Read access to the current route via the `Route` field. Support for more than one input arguments (map to dynamic request path parameters). Register one or more relative paths and able to get path parameters, i.e Response via output arguments, optionally, i.e Where `any` means everything, from custom structs to standard language's types-. `Result` is an interface which contains only that function: Dispatch(ctx iris.Context) and Get where HTTP Method function(Post, Put, Delete...). Iris has a very powerful and blazing fast MVC support, you can return any value of any type from a method function and it will be sent to the client as expected. * if `string` then it's the body. * if `string` is the second output argument then it's the content type. * if `int` then it's the status code. * if `bool` is false then it throws 404 not found http error by skipping everything else. * if `error` and not nil then (any type) response will be omitted and error's text with a 400 bad request will be rendered instead. * if `(int, error)` and error is not nil then the response result will be the error's text with the status code as `int`. * if `custom struct` or `interface{}` or `slice` or `map` then it will be rendered as json, unless a `string` content type is following. * if `mvc.Result` then it executes its `Dispatch` function, so good design patters can be used to split the model's logic where needed. The example below is not intended to be used in production but it's a good showcase of some of the return types we saw before; Another good example with a typical folder structure, that many developers are used to work, can be found at: https://github.com/kataras/iris/tree/v8/_examples/mvc/overview.

Package autorest implements an HTTP request pipeline suitable for use across multiple go-routines and provides the shared routines relied on by AutoRest (see https://github.com/Azure/autorest/) generated Go code. The package breaks sending and responding to HTTP requests into three phases: Preparing, Sending, and Responding. A typical pattern is: Each phase relies on decorators to modify and / or manage processing. Decorators may first modify and then pass the data along, pass the data first and then modify the result, or wrap themselves around passing the data (such as a logger might do). Decorators run in the order provided. For example, the following: will set the URL to: Preparers and Responders may be shared and re-used (assuming the underlying decorators support sharing and re-use). Performant use is obtained by creating one or more Preparers and Responders shared among multiple go-routines, and a single Sender shared among multiple sending go-routines, all bound together by means of input / output channels. Decorators hold their passed state within a closure (such as the path components in the example above). Be careful to share Preparers and Responders only in a context where such held state applies. For example, it may not make sense to share a Preparer that applies a query string from a fixed set of values. Similarly, sharing a Responder that reads the response body into a passed struct (e.g., ByUnmarshallingJson) is likely incorrect. Lastly, the Swagger specification (https://swagger.io) that drives AutoRest (https://github.com/Azure/autorest/) precisely defines two date forms: date and date-time. The github.com/Azure/go-autorest/autorest/date package provides time.Time derivations to ensure correct parsing and formatting. Errors raised by autorest objects and methods will conform to the autorest.Error interface. See the included examples for more detail. For details on the suggested use of this package by generated clients, see the Client described below.

Package tk9.0 is a CGo-free, cross platform GUI toolkit for Go. It is similar to Tkinter for Python. Also available in _examples/hello.go To execute the above program on any supported target issue something like The CGO_ENABLED=0 is optional and here it only demonstrates the program can be built without CGo. Do I need to install the Tcl/Tk libraries on my system to use this package or programs that import it? No. You still have to have a desktop environment installed on systems where that is not necessarily the case by default. That means some of the unix-like systems. Usually installing any desktop environment, like Gnome, Xfce etc. provides all the required library (.so) files. The minimum is the X Window System and this package was tested to work there, although with all the limitations one can expect in this case. Windows: How to build an executable that doesn't open a console window when run? From the documentation for cmd/link: On Windows, -H windowsgui writes a "GUI binary" instead of a "console binary.". To pass the flag to the Go build system use 'go build -ldflags -H=windowsgui somefile.go', for example. What does CGo-free really mean? cgo is a tool used by the Go build system when Go code uses the pseudo-import "C". For technical details please see the link. For us it is important that using CGo ends up invoking a C compiler during building of a Go program/package. The C compiler is used to determine exact, possibly locally dependent, values of C preprocessor constants and other defines, as well as the exact layout of C structs. This enables the Go compiler to correctly handle things like, schematically `C.someStruct.someField` appearing in Go code. At runtime a Go program using CGo must switch stacks when calling into C. Additionally the runtime scheduler is made aware of such calls into C. The former is necessary, the later is not, but it is good to have as it improves performance and provides better resource management. There is an evironment variable defined, `CGO_ENABLED`. When the Go build system compiles Go code, it checks for the value of this env var. If it is not set or its value is "1", then CGo is enabled and used when 'import "C"' is encountered. If the env var contains "0", CGo is disabled and programs using 'import "C"' will not compile. After this longish intro we can finally get to the short answer: CGo-free means this package can be compiled with CGO_ENABLED=0. In other words, there's no 'import "C"' clause anywhere. The consequences of being CGo-free follows from the above. The Go build system does not need to invoke a C compiler when compiling this package. Hence users don't have to have a C compiler installed in their machines. There are advantages when a C compiler is not invoked during compilation/build of Go code. Programs can be installed on all targets supported by this package the easy way: '$ go install example.com/foo@latest' and programs for all supported targets can be cross-compiled on all Go-supported targets just by setting the respective env vars, like performing '$ GOOS=darwin GOARCH=arm64 go build' on a Windows/AMD64 machine, for example. How does this package achieve being CGo-free? The answer depends on the particular target in question. Targets supported by purego call into the Tcl/Tk C libraries without using CGo. See the source code at the link for how it is done. On other targets CGo is avoided by transpiling all the C libraries and their transitive dependencies to Go. In both cases the advantages are the same: CGo-free programs are go-installable and CGo-free programs can be cross-compiled without having a C compiler or a cross-C compiler tool chain installed. Does being CGo-free remove the overhead of crossing the Go-C boundary? For the purego targets, no. Only the C compiler is not involved anymore. For other supported targets the boundary for calling Tcl/Tk C API from Go is gone. No free lunches though, the transpilled code has to care about additional things the C code does not need to - with the respective performance penalties, now just in different places. Consider this program in _examples/debugging.go: Execute the program using the tags as indicated, then close the window or click the Hello button. With the tk.dmesg tag the package initialization prints the debug messages path. So we can view it, for example, like this: 18876 was the process PID in this particular run. Using the tags allows to inspect the Tcl/Tk code executed during the lifetime of the process. These combinations of GOOS and GOARCH are currently supported Specific to FreeBSD: When building with cross-compiling or CGO_ENABLED=0, add the following argument to `go` so that these symbols are defined by making fakecgo the Cgo. Builder results available at modern-c.appspot.com. At the moment the package is a MVP allowing to build at least some simple, yet useful programs. The full Tk API is not yet usable. Please report needed, but non-exposed Tk features at the issue tracker, thanks. Providing feedback about the missing building blocks, bugs and your user experience is invaluable in helping this package to eventually reach version 1. See also RERO. The ErrorMode variable selects the behaviour on errors for certain functions that do not return error. When ErrorMode is PanicOnError, the default, errors will panic, providing a stack trace. When ErrorMode is CollectErrors, errors will be recorded using errors.Join in the Error variable. Even if a function does not return error, it is still possible to handle errors in the usual way when needed, except that Error is now a static variable. That's a problem in the general case, but less so in this package that must be used from a single goroutine only, as documented elsewhere. This is obviously a compromise enabling to have a way to check for errors and, at the same time, the ability to write concise code like: There are altogether four different places where the call to the Button function can produce errors as additionally to the call itself, every of its three arguments can independently fail as well. Checking each and one of them separately is not always necessary in GUI code. But the explicit option in the first example is still available when needed. There is a centralized theme register in Themes. Theme providers can opt in to call RegisterTheme at package initialization to make themes discoverable at run-time. Clients can use ActivateTheme to apply a theme by name. Example in _examples/azure.go. There is a VNC over wbesockets functionality available for X11 backed hosts. See the tk9.0/vnc package for details. Package initialization is done lazily. This saves noticeable additional startup time and avoids screen flicker in hybrid programs that use the GUI only on demand. (For a hybrid example see _examples/ring.go.) Early package initialization can be enforced by Initialize. Initialization will fail if a Unix process starts on a machine with no X server or the process is started in a way that it has no access to the X server. On the other hand, this package may work on Unix machines with no X server if the process is started remotely using '$ ssh -X foo@bar' and the X forwarding is enabled/supported. Darwin port uses the macOS GUI API and does not use X11. Zero or more options can be specified when creating a widget. For example or Tcl/Tk uses widget pathnames, image and font names explicitly set by user code. This package generates those names automatically and they are not directly needed in code that uses this package. There is, for a example, a Tcl/tk 'text' widget and a '-text' option. This package exports the widget as type 'TextWidget', its constructor as function 'Text' and the option as function 'Txt'. The complete list is: This package should be used from the same goroutine that initialized the package. Package initialization performs a runtime.LockOSThread, meaning func main() will start execuing locked on the same OS thread. The Command() and similar options expect an argument that must be one of: - An EventHandler or a function literal of the same signature. - A func(). This can be used when the handler does not need the associated Event instance. When passing an argument of type time.Durarion to a function accepting 'any', the duration is converted to an integer number of milliseconds. When passing an argument of type image.Image to a function accepting 'any', the image is converted to a encoding/base64 encoded string of the PNG representation of the image. When passing an argument of type []byte to a function accepting 'any', the byte slice is converted to a encoding/base64 encoded string. When passing an argument of type []FileType to a function accepting 'any', the slice is converted to the representation the Tcl/Tk -filetypes option expects. At least some minimal knowledge of reading Tcl/Tk code is probably required for using this package and/or using the related documentation. However you will not need to write any Tcl code and you do not need to care about the grammar of Tcl words/string literals and how it differs from Go. There are several Tcl/Tk tutorials available, for example at tutorialspoint. Merge requests for known issues are always welcome. Please send merge requests for new features/APIs after filling and discussing the additions/changes at the issue tracker first. Most of the documentation is generated directly from the Tcl/Tk documentation and may not be entirely correct for the Go package. Those parts hopefully still serve as a quick/offline Tcl/Tk reference. Parts of the documentation are copied and/or modified from the tcl.tk site, see the LICENSE-TCLTK file for details.

Package touchfile provides a mechanism to create, lock, and manage a touch file for coordinating access between different processes. Mutexes are used to coordinate between goroutines. Touch files are used to coordinate between different processes. Because touch files aren't truly atomic, this package uses flock to acquire a voluntary lock on the file. This package creates a temporary file (unless otherwise specified) to use as a lock file. A voluntary lock is acquired on the file using the flock system call. WARNING: Like all go code related to concurrency, this module is NOT reentrant. And because go doesn't have a way to detect reentrancy, it's up to the caller to avoid deadlocks caused by concurrent access to this module. WARNING: Because flock is used, this module may not be compatible with all file systems (notably networked file systems like NFS). Example usage: Basic usage: Global lock using the program binary: Using WithLock for a critical section:

Package seamless implements a seamless restart strategy for daemons monitored by a service supervisor expecting non-forking daemons like daemontools, runit, systemd etc. The seamless strategy is to fully rely on the service supervisor to restart the daemon, while providing to the daemon the full control of the restart process. To achieve this, seamless duplicates the daemon at startup in order to establish a supervisor -> launcher -> daemon relationship. The launcher is the first generation of the daemon hijacked by seamless to act as a circuit breaker between the supervisor and the supervised process. This way, when the supervisor sends a TERM signal to stop the daemon, the launcher intercepts the signal and send an USR2 signal to its child (the actual daemon). In the daemon, seamless intercepts the USR2 signals to initiate the first stage of the seamless restart. During the first stage, the daemon prepare itself to welcome a new version of itself by creating a PID file (see below) and by for instance closing file descriptors. At this point, the daemon is still supposed to accept requests. Once read, seamless sends a CHLD signal by default (or one defined by the user in SetParentTermSignal) back to the launcher (parent) on behalf of the child daemon. Upon reception, the launcher, immediately die, cutting to link between the supervisor and the daemon, making the supervisor attempting a restart of the daemon while current daemon is still running, detached and unsupervised. Once the supervisor restarted the daemon, the daemon can start serving traffic in place of the old (still running) daemon by rebinding sockets using SO_REUSEPORT for instance (see different strategies in examples/). This is the second stage of the seamless restart. When ready, the new daemon calls seamless.Started which will look for a PID file, and if found, will send a TERM signal to the old daemon using the PID found in this file. When the old daemon receives this TERM signal, the third and last stage of the seamless restart is engaged. The OnShutdown function is called so the daemon can gracefully shutdown using Go 1.8 http graceful Shutdown method for instance. This stage can last as long as you decide. When done, the old process can exit in order to conclude the seamless restart. Seamless does not try to implement the actual graceful shutdown or to manage sockets migration. This task is left to the caller. See the examples directory for different implementations.

Package sqlite provides a Go interface to SQLite 3. The semantics of this package are deliberately close to the SQLite3 C API, so it is helpful to be familiar with http://www.sqlite.org/c3ref/intro.html. An SQLite connection is represented by a *sqlite.Conn. Connections cannot be used concurrently. A typical Go program will create a pool of connections (using Open to create a *sqlitex.Pool) so goroutines can borrow a connection while they need to talk to the database. This package assumes SQLite will be used concurrently by the process through several connections, so the build options for SQLite enable multi-threading and the shared cache: https://www.sqlite.org/sharedcache.html The implementation automatically handles shared cache locking, see the documentation on Stmt.Step for details. The optional SQLite3 compiled in are: FTS5, RTree, JSON1, Session, GeoPoly This is not a database/sql driver. Statements are prepared with the Prepare and PrepareTransient methods. When using Prepare, statements are keyed inside a connection by the original query string used to create them. This means long-running high-performance code paths can write: After all the connections in a pool have been warmed up by passing through one of these Prepare calls, subsequent calls are simply a map lookup that returns an existing statement. The sqlite package supports the SQLite incremental I/O interface for streaming blob data into and out of the the database without loading the entire blob into a single []byte. (This is important when working either with very large blobs, or more commonly, a large number of moderate-sized blobs concurrently.) To write a blob, first use an INSERT statement to set the size of the blob and assign a rowid: Use BindZeroBlob or SetZeroBlob to set the size of myblob. Then you can open the blob with: Every connection can have a done channel associated with it using the SetInterrupt method. This is typically the channel returned by a context.Context Done method. For example, a timeout can be associated with a connection session: As database connections are long-lived, the SetInterrupt method can be called multiple times to reset the associated lifetime. When using pools, the shorthand for associating a context with a connection is: SQLite transactions have to be managed manually with this package by directly calling BEGIN / COMMIT / ROLLBACK or SAVEPOINT / RELEASE/ ROLLBACK. The sqlitex has a Savepoint function that helps automate this. Using a Pool to execute SQL in a concurrent HTTP handler. For helper functions that make some kinds of statements easier to write see the sqlitex package.

Zen is a set of small utilities that you probably miss. It's a common situation when simple things drive you crazy like missing ternary operator, mutex locking/unlocking for simple read/assignment, dealing with complex loops due to missing slice operations, or having to deal with goroutines and synchronization even for simple things. Zen tries to solve it. Not solves, but definitely tries. It provides you with a number of small packages to make your work with Go easier. Let's look at a fairly common situation where you need to filter a slice. It's really annoying, isn't it? The language has no built-in capabilities for doing such operations inline. Let's see what it would look like with our package. Need to convert a slice of values to something different? Not a big deal. Just give a processing function to "slice.Map". Let's look at another example. Sometimes you run into situations where the structure takes a pointer to a simple type, like string. It's understandable, sometimes we need to take nil as one of the possible states. But if we will try to create a pointer from an inline value, we get an error. So you'll end up defining one more variable before creating the struct. Now you can sleep peacefully. Let's move on to the next example, which is very similar. They all look alike, don't they? Now, we will try to implement "default value". Of course, without any additional methods or wrappers it would look something like this. Our "logic" mini-package just makes our lives a little easier. Need some kind of async/await instead of managing mutexes by hand? Yep, sure. In addition to the above, the library contains many interesting things that go beyond a basic overview. First, check the library index to explore the proposed sub-packages. Each one has its own mini-documentation, its own index, and consists of well-documented types and functions. Zen has been trying to be modular since v3, so it now consists of sub-packages and does not provide anything from the root package, except the package overview.
