+# matterbridge
+
+Simple bridge between mattermost, IRC, XMPP, Gitter and Slack
+
+* Relays public channel messages between mattermost, IRC, XMPP, Gitter and Slack. Pick and mix.
+* Supports multiple channels.
+* Matterbridge can also work with private groups on your mattermost.
+
+Look at [matterbridge.conf.sample] (https://github.com/42wim/matterbridge/blob/master/matterbridge.conf.sample) for documentation and an example.
+
+## Changelog
+Since v0.6.1 support for XMPP, Gitter and Slack is added. More details in [changelog.md] (https://github.com/42wim/matterbridge/blob/master/changelog.md)
+
+## Requirements:
+Accounts to one of the supported bridges
+* [Mattermost] (https://github.com/mattermost/platform/)
+* [IRC] (http://www.mirc.com/servers.html)
+* [XMPP] (https://jabber.org)
+* [Gitter] (https://gitter.im)
+* [Slack] (https://www.slack.com)
+
+## binaries
+Binaries can be found [here] (https://github.com/42wim/matterbridge/releases/)
+* For use with mattermost 3.3.0+ [v0.6.1](https://github.com/42wim/matterircd/releases/tag/v0.6.1)
+* For use with mattermost 3.0.0-3.2.0 [v0.5.0](https://github.com/42wim/matterircd/releases/tag/v0.5.0)
+
+
+## Docker
+Create your matterbridge.conf file locally eg in ```/tmp/matterbridge.conf```
+
+```
+docker run -ti -v /tmp/matterbridge.conf:/matterbridge.conf 42wim/matterbridge:0.6.1
+```
+
+## Compatibility
+### Mattermost 
+* Matterbridge v0.6.1 works with mattermost 3.3.0 and higher [3.3.0 release](https://github.com/mattermost/platform/releases/tag/v3.3.0)
+* Matterbridge v0.5.0 works with mattermost 3.0.0 - 3.2.0 [3.2.0 release](https://github.com/mattermost/platform/releases/tag/v3.2.0)
+
+
+#### Webhooks version
+* Configured incoming/outgoing [webhooks](https://www.mattermost.org/webhooks/) on your mattermost instance.
+
+#### Plus (API) version
+* A dedicated user(bot) on your mattermost instance.
+
+
+## building
+Go 1.6+ is required. Make sure you have [Go](https://golang.org/doc/install) properly installed, including setting up your [GOPATH] (https://golang.org/doc/code.html#GOPATH)
+
+```
+cd $GOPATH
+go get github.com/42wim/matterbridge
+```
+
+You should now have matterbridge binary in the bin directory:
+
+```
+$ ls bin/
+matterbridge
+```
+
+## running
+1) Copy the matterbridge.conf.sample to matterbridge.conf in the same directory as the matterbridge binary.  
+2) Edit matterbridge.conf with the settings for your environment. See below for more config information.  
+3) Now you can run matterbridge. 
+
+```
+Usage of ./matterbridge:
+  -conf string
+        config file (default "matterbridge.conf")
+  -debug
+        enable debug
+  -plus
+        running using API instead of webhooks (deprecated, set Plus flag in [general] config)
+  -version
+        show version
+```
+
+## config
+### matterbridge
+matterbridge looks for matterbridge.conf in current directory. (use -conf to specify another file)
+
+Look at [matterbridge.conf.sample] (https://github.com/42wim/matterbridge/blob/master/matterbridge.conf.sample) for an example.
+
+### mattermost
+#### webhooks version
+You'll have to configure the incoming and outgoing webhooks. 
+
+* incoming webhooks
+Go to "account settings" - integrations - "incoming webhooks".  
+Choose a channel at "Add a new incoming webhook", this will create a webhook URL right below.  
+This URL should be set in the matterbridge.conf in the [mattermost] section (see above)  
+
+* outgoing webhooks
+Go to "account settings" - integrations - "outgoing webhooks".  
+Choose a channel (the same as the one from incoming webhooks) and fill in the address and port of the server matterbridge will run on.  
+
+e.g. http://192.168.1.1:9999 (192.168.1.1:9999 is the BindAddress specified in [mattermost] section of matterbridge.conf)
+
+#### plus version
+You'll have to create a new dedicated user on your mattermost instance.
+Specify the login and password in [mattermost] section of matterbridge.conf
+
+## FAQ
+Please look at [matterbridge.conf.sample] (https://github.com/42wim/matterbridge/blob/master/matterbridge.conf.sample) for more information first. 
+### Mattermost doesn't show the IRC nicks
+If you're running the webhooks version, this can be fixed by either:
+* enabling "override usernames". See [mattermost documentation](http://docs.mattermost.com/developer/webhooks-incoming.html#enabling-incoming-webhooks)
+* setting ```PrefixMessagesWithNick``` to ```true``` in ```mattermost``` section of your matterbridge.conf.
+
+If you're running the plus version you'll need to:
+* setting ```PrefixMessagesWithNick``` to ```true``` in ```mattermost``` section of your matterbridge.conf.
+
+Also look at the ```RemoteNickFormat``` setting.

+Package toml provides facilities for decoding and encoding TOML configuration
+files via reflection. There is also support for delaying decoding with
+the Primitive type, and querying the set of keys in a TOML document with the
+MetaData type.
+
+The specification implemented: https://github.com/toml-lang/toml
+
+The sub-command github.com/BurntSushi/toml/cmd/tomlv can be used to verify
+whether a file is a valid TOML document. It can also be used to print the
+type of each key in a TOML document.
+
+Testing
+
+There are two important types of tests used for this package. The first is
+contained inside '*_test.go' files and uses the standard Go unit testing
+framework. These tests are primarily devoted to holistically testing the
+decoder and encoder.
+
+The second type of testing is used to verify the implementation's adherence
+to the TOML specification. These tests have been factored into their own
+project: https://github.com/BurntSushi/toml-test
+
+The reason the tests are in a separate project is so that they can be used by
+any implementation of TOML. Namely, it is language agnostic.

+
+// Package log4go provides level-based and highly configurable logging.
+//
+// Enhanced Logging
+//
+// This is inspired by the logging functionality in Java.  Essentially, you create a Logger
+// object and create output filters for it.  You can send whatever you want to the Logger,
+// and it will filter that based on your settings and send it to the outputs.  This way, you
+// can put as much debug code in your program as you want, and when you're done you can filter
+// out the mundane messages so only the important ones show up.
+//
+// Utility functions are provided to make life easier. Here is some example code to get started:
+//
+// log := log4go.NewLogger()
+// log.AddFilter("stdout", log4go.DEBUG, log4go.NewConsoleLogWriter())
+// log.AddFilter("log",    log4go.FINE,  log4go.NewFileLogWriter("example.log", true))
+// log.Info("The time is now: %s", time.LocalTime().Format("15:04:05 MST 2006/01/02"))
+//
+// The first two lines can be combined with the utility NewDefaultLogger:
+//
+// log := log4go.NewDefaultLogger(log4go.DEBUG)
+// log.AddFilter("log",    log4go.FINE,  log4go.NewFileLogWriter("example.log", true))
+// log.Info("The time is now: %s", time.LocalTime().Format("15:04:05 MST 2006/01/02"))
+//
+// Usage notes:
+// - The ConsoleLogWriter does not display the source of the message to standard
+//   output, but the FileLogWriter does.
+// - The utility functions (Info, Debug, Warn, etc) derive their source from the
+//   calling function, and this incurs extra overhead.
+//
+// Changes from 2.0:
+// - The external interface has remained mostly stable, but a lot of the
+//   internals have been changed, so if you depended on any of this or created
+//   your own LogWriter, then you will probably have to update your code.  In
+//   particular, Logger is now a map and ConsoleLogWriter is now a channel
+//   behind-the-scenes, and the LogWrite method no longer has return values.
+//
+// Future work: (please let me know if you think I should work on any of these particularly)
+// - Log file rotation
+// - Logging configuration files ala log4j
+// - Have the ability to remove filters?
+// - Have GetInfoChannel, GetDebugChannel, etc return a chan string that allows
+//   for another method of logging
+// - Add an XML filter type
