+# Fluux XMPP Changelog
+
+## v0.5.0
+
+### Changes
+
+- Added support for XEP-0198 (Stream management)
+- Added message queue : when using "SendX" methods on a client, messages are also stored in a queue. When requesting
+acks from the server, sent messages will be discarded, and unsent ones will be sent again. (see https://xmpp.org/extensions/xep-0198.html#acking)
+- Added support for stanza_errors (see https://xmpp.org/rfcs/rfc3920.html#def C.2.  Stream error namespace and https://xmpp.org/rfcs/rfc6120.html#schemas-streamerror)
+- Added separate hooks for connection and reconnection on the client. One can now specify different actions to get triggered on client connect 
+and reconnect, at client init time.
+- Client state update is now thread safe
+- Changed the Config struct to use pointer semantics
+- Tests
+- Refactoring, including removing some Fprintf statements in favor of Marshal + Write and using structs from the library
+instead of strings
+
+## v0.4.0
+
+### Changes
+
+- Added support for XEP-0060 (PubSub)  
+(no support for 6.5.4 Returning Some Items yet as it needs XEP-0059, Result Sets)
+- Added support for XEP-0050 (Commands)
+- Added support for XEP-0004 (Forms)
+- Updated the client example with a TUI
+- Make keepalive interval configurable #134
+- Fix updating of EventManager.CurrentState #136
+- Added callbacks for error management in Component and Client. Users must now provide a callback function when using NewClient/Component.
+- Moved JID from xmpp package to stanza package
+
+## v0.3.0
+
+### Changes
+
+- Update requirements to go1.13
+- Add a websocket transport
+- Add Client.SendIQ method
+- Add IQ result routes to the Router
+- Fix SIGSEGV in xmpp_component (#126)
+- Add tests for Component and code style fixes
+
+## v0.2.0
+
+### Changes
+
+- XMPP Over Websocket support
+- Add support for getting IQ responses to client IQ queries (synchronously or asynchronously, passing an handler
+  function).
+- Implement X-OAUTH2 authentication method. You can read more details here:
+  [Understanding ejabberd OAuth Support & Roadmap: Step 4](https://blog.process-one.net/understanding-ejabberd-oauth-support-roadmap/)

+# Contributing
+
+We'd love for you to contribute to our source code and to make our project even better than it is
+today! Here are the guidelines we'd like you to follow:
+
+* [Code of Conduct](#coc)
+* [Questions and Problems](#question)
+* [Issues and Bugs](#issue)
+* [Feature Requests](#feature)
+* [Issue Submission Guidelines](#submit)
+* [Pull Request Submission Guidelines](#submit-pr)

+
+## <a name="coc"></a> Code of Conduct
+
+Help us keep our community open-minded and inclusive. Please read and follow our [Code of Conduct][coc].
+
+## <a name="requests"></a> Questions, Bugs, Features
+
+### <a name="question"></a> Got a Question or Problem?
+
+Do not open issues for general support questions as we want to keep GitHub issues for bug reports
+and feature requests. You've got much better chances of getting your question answered on dedicated
+support platforms, the best being [Stack Overflow][stackoverflow].
+
+Stack Overflow is a much better place to ask questions since:
+
+- there are thousands of people willing to help on Stack Overflow
+- questions and answers stay available for public viewing so your question / answer might help
+  someone else
+- Stack Overflow's voting system assures that the best answers are prominently visible.
+
+To save your and our time, we will systematically close all issues that are requests for general
+support and redirect people to the section you are reading right now.
+
+### <a name="issue"></a> Found an Issue or Bug?
+
+If you find a bug in the source code, you can help us by submitting an issue to our
+[GitHub Repository][github]. Even better, you can submit a Pull Request with a fix.
+
+### <a name="feature"></a> Missing a Feature?
+
+You can request a new feature by submitting an issue to our [GitHub Repository][github-issues].
+
+If you would like to implement a new feature then consider what kind of change it is:
+
+* **Major Changes** that you wish to contribute to the project should be discussed first in an
+  [GitHub issue][github-issues] that clearly outlines the changes and benefits of the feature.
+* **Small Changes** can directly be crafted and submitted to the [GitHub Repository][github]
+  as a Pull Request. See the section about [Pull Request Submission Guidelines](#submit-pr).
+
+## <a name="submit"></a> Issue Submission Guidelines
+
+Before you submit your issue search the archive, maybe your question was already answered.
+
+If your issue appears to be a bug, and hasn't been reported, open a new issue. Help us to maximize
+the effort we can spend fixing issues and adding new features, by not reporting duplicate issues.
+
+The "[new issue][github-new-issue]" form contains a number of prompts that you should fill out to
+make it easier to understand and categorize the issue.
+
+## <a name="submit-pr"></a> Pull Request Submission Guidelines
+
+By submitting a pull request for a code or doc contribution, you need to have the right
+to grant your contribution's copyright license to ProcessOne. Please check [ProcessOne CLA][cla]
+for details.
+
+Before you submit your pull request consider the following guidelines:
+
+* Search [GitHub][github-pr] for an open or closed Pull Request
+  that relates to your submission. You don't want to duplicate effort.
+* Make your changes in a new git branch:
+
+    ```shell
+    git checkout -b my-fix-branch master
+    ```
+* Test your changes and, if relevant, expand the automated test suite.
+* Create your patch commit, including appropriate test cases.
+* If the changes affect public APIs, change or add relevant documentation.
+* Commit your changes using a descriptive commit message.
+
+    ```shell
+    git commit -a
+    ```
+  Note: the optional commit `-a` command line option will automatically "add" and "rm" edited files.
+
+* Push your branch to GitHub:
+
+    ```shell
+    git push origin my-fix-branch
+    ```
+
+* In GitHub, send a pull request to `master` branch. This will trigger the continuous integration and run the test.
+We will also notify you if you have not yet signed the [contribution agreement][cla].
+
+* If you find that the continunous integration has failed, look into the logs to find out
+if your changes caused test failures, the commit message was malformed etc. If you find that the
+tests failed or times out for unrelated reasons, you can ping a team member so that the build can be
+restarted.
+
+* If we suggest changes, then:
+
+  * Make the required updates.
+  * Test your changes and test cases.
+  * Commit your changes to your branch (e.g. `my-fix-branch`).
+  * Push the changes to your GitHub repository (this will update your Pull Request).
+
+    You can also amend the initial commits and force push them to the branch.
+
+    ```shell
+    git rebase master -i
+    git push origin my-fix-branch -f
+    ```
+
+    This is generally easier to follow, but separate commits are useful if the Pull Request contains
+    iterations that might be interesting to see side-by-side.
+
+That's it! Thank you for your contribution!
+
+## <a name="cla"></a> Signing the Contributor License Agreement (CLA)
+
+Upon submitting a Pull Request, we will ask you to sign our CLA if you haven't done
+so before. It's a quick process, we promise, and you will be able to do it all online
+
+You can read [ProcessOne Contribution License Agreement][cla] in PDF.
+
+This is part of the legal framework of the open-source ecosystem that adds some red tape,
+but protects both the contributor and the company / foundation behind the project. It also
+gives us the option to relicense the code with a more permissive license in the future.

+# Fluux XMPP
+
+[![GoDoc](https://godoc.org/gosrc.io/xmpp?status.svg)](https://godoc.org/gosrc.io/xmpp) [![GoReportCard](https://goreportcard.com/badge/gosrc.io/xmpp)](https://goreportcard.com/report/fluux.io/xmpp) [![Coverage Status](https://coveralls.io/repos/github/FluuxIO/go-xmpp/badge.svg?branch=master)](https://coveralls.io/github/FluuxIO/go-xmpp?branch=master)
+
+Fluux XMPP is a Go XMPP library, focusing on simplicity, simple automation, and IoT.
+
+The goal is to make simple to write simple XMPP clients and components:
+
+- For automation (like for example monitoring of an XMPP service),
+- For building connected "things" by plugging them on an XMPP server,
+- For writing simple chatbot to control a service or a thing,
+- For writing XMPP servers components.
+
+The library is designed to have minimal dependencies. Currently it requires at least Go 1.13.
+
+## Configuration and connection
+
+### Allowing Insecure TLS connection during development
+
+It is not recommended to disable the check for domain name and certificate chain. Doing so would open your client
+to man-in-the-middle attacks.
+
+However, in development, XMPP servers often use self-signed certificates. In that situation, it is better to add the
+root CA that signed the certificate to your trusted list of root CA. It avoids changing the code and limit the risk
+of shipping an insecure client to production.
+
+That said, if you really want to allow your client to trust any TLS certificate, you can customize Go standard 
+`tls.Config` and set it in Config struct.
+
+Here is an example code to configure a client to allow connecting to a server with self-signed certificate. Note the 
+`InsecureSkipVerify` option. When using this `tls.Config` option, all the checks on the certificate are skipped.
+
+```go
+config := xmpp.Config{
+	Address:      "localhost:5222",
+	Jid:          "test@localhost",
+	Credential:   xmpp.Password("Test"),
+	TLSConfig:    tls.Config{InsecureSkipVerify: true},
+}
+```
+
+## Supported specifications
+
+### Clients
+
+- [RFC 6120: XMPP Core](https://xmpp.org/rfcs/rfc6120.html)
+- [RFC 6121: XMPP Instant Messaging and Presence](https://xmpp.org/rfcs/rfc6121.html)

+  - [XEP-0356: Privileged Entity](https://xmpp.org/extensions/xep-0356.html)
+
+### Extensions 
+  - [XEP-0060: Publish-Subscribe](https://xmpp.org/extensions/xep-0060.html)  
+    Note : "6.5.4 Returning Some Items" requires support for [XEP-0059: Result Set Management](https://xmpp.org/extensions/xep-0059.html), 
+    and is therefore not supported yet. 
+  - [XEP-0004: Data Forms](https://xmpp.org/extensions/xep-0004.html)
+  - [XEP-0050: Ad-Hoc Commands](https://xmpp.org/extensions/xep-0050.html)
+
+## Package overview
+
+### Stanza subpackage
+
+XMPP stanzas are basic and extensible XML elements. Stanzas (or sometimes special stanzas called 'nonzas') are used to 
+leverage the XMPP protocol features. During a session, a client (or a component) and a server will be exchanging stanzas
+back and forth.
+
+At a low-level, stanzas are XML fragments. However, Fluux XMPP library provides the building blocks to interact with
+stanzas at a high-level, providing a Go-friendly API.
+
+The `stanza` subpackage provides support for XMPP stream parsing, marshalling and unmarshalling of XMPP stanza. It is a
+bridge between high-level Go structure and low-level XMPP protocol.
+
+Parsing, marshalling and unmarshalling is automatically handled by Fluux XMPP client library. As a developer, you will
+generally manipulates only the high-level structs provided by the stanza package.
+
+The XMPP protocol, as the name implies is extensible. If your application is using custom stanza extensions, you can
+implement your own extensions directly in your own application.
+
+To learn more about the stanza package, you can read more in the
+[stanza package documentation](https://github.com/FluuxIO/go-xmpp/blob/master/stanza/README.md).

+	// If you pass the client to a connection manager, it will handle the reconnect policy
+	// for you automatically.
+	cm := xmpp.NewStreamManager(client, nil)
+	log.Fatal(cm.Run())
+}
+
+func handleMessage(s xmpp.Sender, p stanza.Packet) {
+	msg, ok := p.(stanza.Message)
+	if !ok {

+# Chat TUI example
+This is a simple chat example, with a TUI.   
+It shows the library usage and a few of its capabilities. 
+## How to run
+### Build
+You can build the client using : 
+```
+    go build -o example_client
+```
+and then run with (on unix for example): 
+```
+    ./example_client
+```
+or you can simply build + run in one command while at the example directory root, like this:
+```
+    go run xmpp_chat_client.go interface.go 
+```
+
+### Configuration
+The example needs a configuration file to run. A sample file is provided.  
+By default, the example will look for a file named "config" in the current directory.
+To provide a different configuration file, pass the following argument to the example :
+```
+    go run xmpp_chat_client.go interface.go -c /path/to/config
+```
+where /path/to/config is the path to the directory containing the configuration file. The configuration file must be named 
+"config" and be using the yaml format.  
+  
+Required fields are :
+```yaml
+Server :
+  - full_address: "localhost:5222"
+Client : # This is you
+  - jid: "testuser2@localhost"
+  - pass: "pass123" #Password in a config file yay
+
+# Contacts list, ";" separated
+Contacts : "testuser1@localhost;testuser3@localhost"
+# Should we log stanzas ?  
+LogStanzas:
+  - logger_on: "true"
+  - logfile_path: "./logs" # Path to directory, not file.
+```
+
+## How to use
+Shortcuts :   
+    - ctrl+space  : switch between input window and menu window.  
+    - While in input window :  
+        - enter : sends a message if in message mode (see menu options)  
+        - ctrl+e : sends a raw stanza when in raw mode (see menu options)    
+    - ctrl+c : quit

+# xmpp_component
+
+This component will connect to ejabberd and act as a subdomain "service" of your primary XMPP domain
+(in that case localhost).
+
+This component does nothing expect connect and show up in service discovery.
+
+To be able to connect this component, you need to add a listener to your XMPP server.
+
+Here is an example ejabberd configuration for that component listener:
+
+```yaml
+listen:
+...
+  -
+    port: 8888
+    module: ejabberd_service
+    password: "mypass"
+```
+
+ejabberd will listen for a component (service) on port 8888 and allows it to connect using the
+secret "mypass".

+# Jukebox example  
+
+## Requirements
+- You need mpg123 installed on your computer because the example runs it as a command :
+[Official MPG123 website](https://mpg123.de/)  
+Most linux distributions have a package for it.  
+- You need a soundcloud ID to play a music from the website through mpg123. You currently cannot play music files with this example.  
+Your user ID is available in your account settings on the [soundcloud website](https://soundcloud.com/)  
+**One is provided for convenience.**
+- You need a running jabber server. You can run your local instance of [ejabberd](https://www.ejabberd.im/) for example. 
+- You need a registered user on the running jabber server.
+
+## Run
+You can edit the soundcloud ID in the example file with your own, or use the provided one :
+```go
+const scClientID = "dde6a0075614ac4f3bea423863076b22"
+``` 
+
+To run the example, build it with (while in the example directory) :
+```
+go build xmpp_jukebox.go
+```
+
+then run it with (update the command arguments accordingly):
+```
+./xmpp_jukebox -jid=MY_USERE@MY_DOMAIN/jukebox -password=MY_PASSWORD -address=MY_SERVER:MY_SERVER_PORT
+```
+Make sure to have a resource, for instance "/jukebox", on your jid.
+
+Then you can send the following stanza to "MY_USERE@MY_DOMAIN/jukebox" (with the resource) to play a song (update the soundcloud URL accordingly) :
+```xml
+<iq id="1" to="MY_USERE@MY_DOMAIN/jukebox" type="set">
+    <set xml:lang="en" xmlns="urn:xmpp:iot:control">
+        <string name="url" value="https://soundcloud.com/UPDATE/ME"/>

+# PubSub client example
+
+## Description
+This is a simple example of a client that :
+* Creates a node on a service
+* Subscribes to that node
+* Publishes to that node
+* Gets the notification from the publication and prints it on screen
+
+## Requirements
+You need to have a running jabber server, like [ejabberd](https://www.ejabberd.im/) that supports [XEP-0060](https://xmpp.org/extensions/xep-0060.html).
+
+## How to use
+Just run : 
+```
+    go run xmpp_ps_client.go
+```
