Errbot is a chatbot designed to be simple to extend with plugins written in Python.

Project Description


Errbot

Errbot is a chatbot. It allows you to start scripts interactively from your chatrooms for any reason: random humour, chatops, starting a build, monitoring commits, triggering alerts…

It is written and easily extensible in Python.

Errbot is available as open-source software and released under the GPL v3 license.

Features

Administration

After the initial installation and security setup, Errbot can be administered by just chatting to the bot (chatops).

  • install/uninstall/update/enable/disable private or public plugins hosted on git
  • plugins can be configured from chat
  • direct the bot to join/leave Multi User Chatrooms (MUC)
  • Security: ACL control feature (admin/user rights per command)
  • backup: an integrated command !backup creates a full export of persisted data.
  • logs: can be inspected from chat or streamed to Sentry.

Developer features

  • Very easy to extend in Python! (see below)
  • Presetup storage for every plugin i.e. self['foo'] = 'bar' persists the value.
  • Conversation flows to track conversation states from users.
  • Webhook callbacks support
  • supports markdown extras formatting with tables, embedded images, links etc.
  • configuration helper to allow your plugin to be configured by chat
  • Graphical and text development/debug consoles
  • Self-documenting: your docstrings become help automatically
  • subcommands and various arg parsing options are available (re, command line type)
  • polling support: your can setup a plugin to periodically do something
  • end to end test backend
  • card rendering under Slack and Hipchat.

Installation

Prerequisites

Errbot runs under Python 3.3+ on Linux, Windows and Mac. For some chatting systems you’ll need a key or a login for your bot to access it. Note: Python 2 support is still available in errbot-4.2.x, but it is going away.

Quickstart

We recommend to setup a virtualenv.

  1. Install errbot from pip
  2. Make a directory somewhere (here called errbot) to host Errbot’s data files
  3. Initialize the directory
  4. Try out Errbot in text mode
$ pip install errbot
$ mkdir errbot; cd errbot
$ errbot --init
$ errbot

It will show you a prompt >>> so you can talk to your bot directly! Try !help to get started.

Adding support for a chat system

For the built-ins, just use one of those options slack, hipchap, telegram, IRC, XMPP with pip, you can still do it after the initial installation to add the missing support for example

$ pip install "errbot[slack]"

For the external ones (Skype, Gitter, Discord etc …), please follow their respective github pages for instructions.

Configuration

In order to configure Errbot to connect to one of those chat systems you’ll need to tweak the config.py file generated by errbot –init.

To help you, we have a documented template available here: config-template.py.

Note: even if you changed the BACKEND from the configuration, you can still use errbot -T and errbot -G to test out your instance locally (in text and graphic mode respectively).

Starting Errbot as a daemon

If all that worked, you can now use the -d (or –daemon) parameter to run it in a detached mode:

errbot --daemon

Interacting with the Bot

After starting Errbot, you should add the bot to your buddy list if you haven’t already. You’ll need to invite the bot explicitly to chatrooms on some chat systems too. You can now send commands directly to the bot!

To get a list of all available commands, you can issue:

!help

If you just wish to know more about a specific command you can issue:

!help command

Managing plugins

You can administer the bot in a one-on-one chat if your handle is in the BOT_ADMINS list in config.py.

For example to keyword search in the public plugin repos you can issue:

!repos search jira

To install a plugin from this list, issue:

!repos install <name of repo>

For example !repos install errbotio/err-imagebot.

Writing plugins

Writing your own plugins is extremely simple. errbot –init will have installed in the plugins subdirectory a plugin called err-example you can use as a base.

As an example, this is all it takes to create a “Hello, world!” plugin for Errbot:

from errbot import BotPlugin, botcmd

 class Hello(BotPlugin):
     """Example 'Hello, world!' plugin for Errbot"""

     @botcmd
     def hello(self, msg, args):
         """Return the phrase "Hello, world!" to you"""
         return "Hello, world!"

This plugin will create the command “!hello” which, when issued, returns “Hello, world!” to you. For more info on everything you can do with plugins, see the plugin development guide.

Hotfix

  • better README

v4.2.0 (2016-06-10)

v4.2 Announcement

  • Bye bye Python 2 ! This 4.2 branch will be the last to support Python 2. We will maintain bug fixes on it for at least the end of 2016 so you can transition nicely, but please start now !

    Python 3 has been released 8 years ago, now all the major distributions finally have it available, the ecosystem has moved on too. This was not the case at all when we started to port Errbot to Python 3.

    This will clean up a lot of code with ugly if PY2, unicode hacks, 3to2 reverse hacks all over the place and packaging tricks. But most of all it will finally unite the Errbot ecosystem under one language and open up new possibilities as we refrained from using py3 only features.

  • A clarification on Errbot’s license has been accepted. The contributors never intended to have the GPL licence be enforced for external plugins. Even if it was not clear it would apply, our new licence exception makes sure it isn’t. Big big thanks for the amazing turnout on this one !

v4.2 New features

  • Errbot initial installation. The initial installation has been drastically simplified:

    $ pip install errbot
    $ mkdir errbot; cd errbot
    $ errbot --init
    $ errbot -T
    >>>     <- You are game !!
    

    Not only that but it also install a development directory in there so it now takes only seconds to have an Errbot development environment.

  • Part of this change, we also made most of the config.py entries with sane defaults, a lot of those settings were not even relevant for most users.

  • cards are now supported on the graphic backend with a nice rendering (errbot -G)

  • Hipchat: mentions are now supported.

v4.2 Miscellaneous changes

  • Documentation improvements
  • Reorganization and rename of the startup files. Those were historically the first ones to be created and their meaning drifted over the years. We had err.py, main.py and errBot.py, it was really not clear what were their functions and why one has been violating the python module naming convention for so long :) They are now bootstrap.py (everything about configuring errbot), cli.py (everything about the errbot command line) and finally core.py (everything about the commands, and dispatching etc…).
  • setup.py cleanup. The hacks in there were incorrect.

v4.2 fixes

  • core: excpetion formatting was failing on some plugin load failures.
  • core: When replacing the prefix ! from the doctrings only real commands get replaced (thx Raphael Boidol)
  • core: empty lines on plugins requirements.txt does crash errbot anymore
  • core: Better error message in case of malformed .plug file
  • Text: fix on build_identifier (thx Pawet Adamcak)
  • Slack: several fixes for identifiers parsing, the backend is fully compliant with Errbot’s contract now (thx Raphael Boidol and Samuel Loretan)
  • Hipchat: fix on room occupants (thx Roman Forkosh)
  • Hipchat: fix for organizations with more than 100 rooms. (thx Naman Bharadwaj)
  • Hipchat: fixed a crash on build_identifier

v4.1.3 (2016-05-10)

hotfixes:

  • Slack: regression on build_identifier
  • Hipchat: regression on build_identifier (query for room is not supported)

v4.1.2 (2016-05-10)

fixes:

  • cards for hipchat and slack were not merged.

v4.1.1 (2016-05-09)

fixes:

  • Python 2.7 conversion error on err.py.

v4.1.0 (2016-05-09)

v4.1 features

  • Conversation flows: Errbot can now keep track of conversations with its users and automate part of the interactions in a state machine manageable from chat. see the flows documentation for more information.
  • Cards API: Various backends have a “canned” type of formatted response. We now support that for a better native integration with Slack and Hipchat.
  • Dynamic Plugins API: Errbot has now an official API to build plugins at runtime (on the fly). see the dynamic plugins doc
  • Storage command line interface: It is now possible to provision any persistent setting from the command line. It is helpful if you want to automate end to end the deployment of your chatbot. see provisioning doc

v4.1 Miscellaneous changes

  • Now if no [python] section is set in the .plug file, we assume Python 3 instead of Python 2.
  • Slack: identifier.person now gives its username instead of slack id
  • IRC: Topic change callback fixed. Thx Ezequiel Brizuela.
  • Text/Test: Makes the identifier behave more like a real backend.
  • Text: new TEXT_DEMO_MODE that removes the logs once the chat is started: it is made for presentations / demos.
  • XMPP: build_identifier can now resolve a Room (it will eventually be available on other backends)
  • Graphic Test backend: renders way better the chat, TEXT_DEMO_MODE makes it full screen for your presentations.
  • ACLs: We now allow a simple string as an entry with only one element.
  • Unit Tests are now all pure py.test instead of a mix of (py.test, nose and unittest)

v4.1 fixed

  • Better resillience on concurrent modifications of the commands structures.
  • Allow multiline table cells. Thx Ilya Figotin.
  • Plugin template was incorrectly showing how to check config. Thx Christian Weiske.
  • Slack: DIVERT_TO_PRIVATE fix.
  • Plugin Activate was not reporting correctly some errors.
  • tar.gz packaged plugins are working again.

fixes:

  • XMPP backend compatibility with python 2.7
  • Telegram startup error
  • daemonize regression
  • UTF-8 detection

v4.0.2 (2016-03-15)

hotfixes:

  • configparser needs to be pinned to a 3.5.0b2 beta
  • Hipchat regression on Identifiers
  • Slack: avoid URI expansion.

v4.0.1 (2016-03-14)

hotfixes:

  • v4 doesn’t migrate plugin repos entries from v3.
  • py2 compatibility.

v4.0.0 (2016-03-13)

This is the next major release of errbot with significant changes under the hood.

v4.0 New features

  • Storage is now implemented as a plugin as well, similar to command plugins and backends. This means you can now select different storage implementations or even write your own.

The following storage backends are currently available:

  • The traditional Python shelf storage.
  • In-memory storage for tests or ephemeral storage.
  • SQL storage which supports relational databases such as MySQL, Postgres, Redshift etc.
  • Firebase storage for the Google Firebase DB.
  • Redis storage (thanks Sijis Aviles!) which uses the Redis in-memory data structure store.
  • Unix-style glob support in BOT_ADMINS and ACCESS_CONTROLS (see the updated config-template.py for documentation).
  • The ability to apply ACLs to all commands exposed by a plugin (see the updated config-template.py for documentation).
  • The mention_callcack() on IRC (mr. Shu).
  • A new (externally maintained) Skype backend.
  • The ability to disable core plugins (such as !help, !status, etc) from loading (see CORE_PLUGINS in the updated config-template.py).
  • Added a –new-plugin flag to errbot which can create an emply plugin skeleton for you.
  • IPv6 configuration support on IRC (Mike Burke)
  • More flexible access controls on IRC based on nickmasks (in part thanks to Marcus Carlsson). IRC users, see the new IRC_ACL_PATTERN in config-template.py.
  • A new callback_mention() for plugins (not available on all backends).
  • Admins are now notified about plugin startup errors which happen during bot startup
  • The repos listed by the !repos command are now fetched from a public index and can be queried with !repos query [keyword]. Additionally, it is now possible to add your own index(es) to this list as well in case you wish to maintain a private index (special thanks to Sijis Aviles for the initial proof-of-concept implementation).

v4.0 fixed

  • IRC backend no longer crashes on invalid UTF-8 characters but instead replaces them (mr. Shu).
  • Fixed joining password-protected rooms (Mikko Lehto)
  • Compatibility to API changes introduced in slackclient-1.0.0 (used by the Slack backend).
  • Corrected room joining on IRC (Ezequiel Hector Brizuela).
  • Fixed “team_join event handler raised an exception” on Slack.
  • Fixed DIVERT_TO_PRIVATE on HipChat.
  • Fixed DIVERT_TO_PRIVATE on Slack.
  • Fixed GROUPCHAT_NICK_PREFIXED not prefixing the user on regular commands.
  • Fixed HIDE_RESTRICTED_ACCESS from accidentally sending messages when issuing !help.
  • Fixed DIVERT_TO_PRIVATE on IRC.
  • Fixed markdown rendering breaking with GROUPCHAT_NICK_PREFIXED enabled.
  • Fixed AttributeError with AUTOINSTALL_DEPS enabled.
  • IRC backend now cleanly disconnects from IRC servers instead of just cutting the connection.
  • Text mode now displays the prompt beneath the log output
  • Plugins which fail to install no longer remain behind, obstructing a new installation attempt

v4.0 Breaking changes

  • The underlying implementation of Identifiers has been drastically refactored to be more clear and correct. This makes it a lot easier to construct Identifiers and send messages to specific people or rooms.
  • The file format for –backup and –restore has changed between 3.x and 4.0 On the v3.2 branch, backup can now backup using the new v4 format with !backupv4 to make it possible to use with –restore on errbot 4.0.

A number of features which had previously been deprecated have now been removed. These include:

  • configure_room and invite_in_room in XMPPBackend (use the equivalent functions on the XMPPRoom object instead)
  • The –xmpp, –hipchat, –slack and –irc command-line options from errbot (set a proper BACKEND in config.py instead).

v 4.0 Miscellaneous changes

  • Version information is now specified in plugin .plug files instead of in the Python class of the plugin.
  • Updated !help output, more similar to Hubot’s help output (James O’Beirne and Sijis Aviles).
  • XHTML-IM output can now be enabled on XMPP again.
  • New –version flag on errbot (mr. Shu).
  • Made !log tail admin only (Nicolas Sebrecht).
  • Made the version checker asynchronous, improving startup times.
  • Optionally allow bot configuration from groupchat
  • Message.type is now deprecated in favor of Message.is_direct and Message.is_group.
  • Some bundled dependencies have been refactored out into external dependencies.
  • Many improvements have been made to the documention, both in docstrings internally as well as the user guide on the website at http://errbot.io.

Further info on identifier changes

  • Person, RoomOccupant and Room are now all equal and can be used as-is to send a message to a person, a person in a Room or a Room itself.

The relationship is as follow:

For example: A Message sent from a room will have a RoomOccupant as frm and a Room as to.

This means that you can now do things like:

  • self.send(msg.frm, “Message”)
  • self.send(self.query_room(“#general”), “Hello everyone”)
