From Meta, a Wikimedia project coordination wiki

wm-bot is an IRC bot that is being used in several Wikimedia IRC channels, particularly developer channels. This page documents the bot. Right now the bot is running on Libera.

The bot is designed to have separate configuration for each channel, so that anyone can get it on their channel and have their own database. The bot is maintained by the user who brought it to the channel, so anyone can configure it as they want.


In case you need any help with this bot, please contact one of its operators:

Getting bot to the channel[edit]

In case you are a Wikimedia or Miraheze user with a Wikimedia or Miraheze cloak and you want to use this bot in a Wikimedia or Miraheze related channel, you can just join #wm-botconnect, where you can type:

@add #nameofchannelyouwant

This make the bot join your channel and give you admin permissions for that channel.

However, there may be some exceptional situations:

Bot will not join[edit]

Bot is probably banned or stuck in some way. For example if you invite a bot and then use freenode's /remove command (which isn't compliant with IRC standards anyway so it makes sense the bot doesn't know it) the bot will still think it's in the channel. You can try to make it part the channel from #wm-bot by calling @part #channel. You will require to be identified with either a Wikimedia or Miraheze IRC cloak, otherwise the bot will ignore your request.

Bot will not give you admin rights[edit]

If the bot was in the channel previously and removed using @part command, it will still have the same ACL so that you won't get admin rights. Instead, the same people as before will have it. You can always contact some of the bot operators to help you in this situation.

User access[edit]


Admin has access to all commands, the user who bring the bot to channel is always made admin unless the bot was previously parted (in that case the previous access list is preserved). This user level can be granted to anyone else using the @trustadd command (see below).


Trusted users have access to most of the commands

If you are a trusted or admin you can use command @trustadd to insert more people to access list

User list[edit]

User list can be controlled using following commands


Display list of users for current channel

@trusted (channel) displays the trust list for (channel)

@trustadd regex level[edit]

Add regex to defined level, level being one of admin, trusted. Example:

@trustadd .*@wikipedia/John trusted

Optionally, you can add a channel name to the end of the command. This will add the regex to the trust list in the specified channel. This can only be done by users with root permissions.

@trustdel regex[edit]

Delete regex, you can only delete users from same or lower access level

Optionally, you can add a channel name to the end of the command. This will delete the regex from the trust list in the specified channel. This can only be done by users with root permissions.

Recent changes feed for WMF wikis[edit]

wm-bot supports a relay of recent changes feed directly to any channel, below is a list of commands which you can use in order to set up the bot

Wiki code examples

  • fr.wikipedia.org
  • meta.wikimedia.org
  • commons.wikimedia.org
  • www.wikidata.org
  • outreach.wikimedia.org
  • wikimania.wikimedia.org
  • incubator.wikimedia.org


Requires admin rights, this command has no parameters

Disables a feed of recent changes of Wikimedia wikis in current channel. The database of pages you configured will be preserved.


Requires admin rights, this command has no parameters

Enables a feed of recent changes in current channel, you can select certain pages on selected wikis to be watched.

@RC- wiki page[edit]

Requires trusted rights, this command has 2 parameters

Removes a page from list of recent changes, affects only current channel.

Example: @RC- en.wikipedia.org User:Test_page

@RC+ wiki page[edit]

Requires trusted rights, this command has 2 parameters

Insert a page to a feed, example @RC+ de.wikipedia.org User:Test_page would make it report changes to de.wikipedia.org/wiki/User:Test_page directly to channel.

Additionally, @RC+ de.wikipedia.org User:Test_page/* would make it report changes to any subpages (but not the primary page) of de.wikipedia.org/wiki/User:Test_page directly to channel. Note that the * wildcard can only be used on the end of the string.


See a list of existing commands for each channel, in https://wm-bot.wmcloud.org/dump/systemdata.htm (Libera) or https://wm-bot.wmflabs.org/dump/systemdata.htm (freenode (historical))

Infobot can be controlled by trusted users using following commands:

<@petan> !key is some data
<wm-bot> Key was added!
<@petan> !key
<wm-bot> some data
<@petan> !key del
<wm-bot> Deleted key
<@petan> !key is this is $1
<wm-bot> Key was added!
<@petan> !key 1
<wm-bot> this is 1
<@petan> !google is https://www.google.com/search?q=$url_encoded_*
<wm-bot> Key was added
<@petan> !google some special symbols % 6 7#%#$%@
<wm-bot> https://www.google.com/search?q=some+special+symbols+%#25+6+7%#23%#25%#23%#24%#25%#40
<@petan> !google some special symbols % 6 7#%#$%@ | addshore
<wm-bot> addshore: https://www.google.com/search?q=some+special+symbols+%#25+6+7%#23%#25%#23%#24%#25%#40
<petan> !highfive act highfives $infobot_nick!
<wm-bot> Key was added
<petan> !highfive
* wm-bot highfives petan!


You can create an alias by typing !key alias key2 so that !key would display value of key2.

The aliases have lower priority than keys so you can overwrite an alias with key (it's possible to create both)

Command !key unalias removes it


Variable Response
$infobot_nick Nick of user who trigger the key
$infobot_host Hostname of user who trigger the key
$1 - $9 Parameters one at a time
$* All parameters in one shot
$url_encoded_1 - $url_encoded_9 URL encoded parameters one at a time
$url_encoded_* All parameters in one shot and URL encoded
$wiki_encoded_1 - $wiki_encoded_9 Wiki encoded parameters one at a time (same as {{URLENCODE: $1 - $9|WIKI}})
$wiki_encoded_* All parameters in one shot and wiki encoded (same as {{URLENCODE: $1 - $9|WIKI}})

@regsearch <regex>[edit]

Search regular expression in all values

@search <word>[edit]

Search key names and values for given word

Private message commands[edit]

You can send a private command to wm-bot like this:

/msg wm-bot @command parameter


This command let you know when specified user becomes active or online. You can use this even on users who aren't registered on the server or even on users who are online, but not active currently.

Example: @notify hashar


@seen user

Tell you when user was last seen

All labs commands[edit]

See help for @labs-*

Channel commands[edit]


Require admin rights

Insert a bot to another channel (@add #example)


Doesn't require any permission

Link to HTML dump of database and channel info (no parameters)



Create a table of channel use statistics to be included in the HTML dump accessible with @info


Stop measuring channel use statistics to be included in the HTML dump accessible with @info

(off by default)


For example if I was waiting for hashar, I could just send a private message

@notify hashar

to wm-bot and he would send me a private message whenever hashar appeared or spoke somewhere. It works even on users who are already online but idle – he then pings you when the user stops being idle.

You can also use this command to send a message to target user when they appear online (as well as notifying you)

@notify petan Hello, cool bot!

Infobot commands[edit]


Requires admin rights

Turn on infobot for current channel


Requires admin rights

Disable infobot on current channel


Requires admin rights

Create a link to infobot db of different channel, this allows you to share infobot with other channels. If you link channel A to channel B's db, the local db of channel A will be no longer accessible, but will not be deleted. If you unlink the channel db, local db will be accessible again.

Example: @infobot-link #mediawiki will make a bot use db of #mediawiki, instead of local db.

Syntax: @infobot-link #channel


Requires admin rights

Enable shared infobot, this is necessary to execute on the channel you want to share the db of with other channels.


Requires admin rights

Remove a channel from trusted relation. This channel will no longer have access to shared db.


Requires admin rights

Insert a channel to db, that means this channel will be allowed to access the shared db for reading and writing.

example: @infobot-share-trust+ #test

this allows #test to link to infobot db of the channel where you triggered this command and to read and write into it, based on own access list.


Requires admin rights

Disable shared infobot


Requires trusted right

Insert a new string to ignore list of infobot, for example

@infobot-ignore+ seen

makes the bot ignore any commands !seen in a channel

This command remove an ignored key from list, syntax: @infobot-ignore- <item>


Doesn't require any rights

Syntax: @infobot-detail <key>

Display information about key


Requires trusted right

Make the key "raw" that means, all special words, $1, $2... will be displayed as they are, instead of converting to specific values, the | symbol is ignored in such a key. Only special word that is respected is $url_encoded_* and $*


Require trusted right

Syntax: @infobot-unset-raw <key>

This command undo the @infobot-set-raw


Requires admin right

example: @infobot-recovery previousdb

Recovers a snapshot—be careful as this operation removes the current database without asking, it's useful to create a snapshot before recovering some other so that you can restore the current db in case something go wrong.

Relay of messages from scripts and other tools[edit]

Useful if you need to send a message to any IRC channel from Wikimedia labs


Requires admin rights

This command is useful if you need to send a message to any IRC channel from Wikimedia Cloud Services/Toolforge, but you don't want to create a bot for that. If you enable relay, anyone on Cloud Services/Toolforge will be able to send a TCP message to wm-bot.wm-bot.wmcloud.org:64835 in format of:

#channel message is here

And a bot will relay it to your channel

Simple shell script to relay "hello world" to channel #wm-bot


echo "#wm-bot hello world" | nc wm-bot.wm-bot.wmcloud.org 64835 64835 -w0


Requires admin rights

Turn off a relay


Requires admin rights

Generate a token for your channel which needs to be provided in a message in order to relay it, example:

#channel TOKEN message is here


Requires admin rights

Disable token

Network bridge[edit]

It's possible to bridge messages between freenode and libera for channels with same name, there are 2 conditions:

  • You need to be admin in both channels on both sides
  • Network relay must be enabled (token-less) on both sides


Requires admin rights

Will relay all messages that don't start with ! or @ to other side, you can also create one-way bridge if you don't run this command on second network


Requires admin rights

Stop sending messages to other side

Operator tools - channel maintenance tool[edit]

Requires admin

Disable optools


Requires admin

Bot will not deop itself after op action


Requires admin

Bot will deop itself after op action


Requires admin

@kb user <reason>

Bot can echo push and commit messages for GitHub repositories to any channel. The detailed setup is below:

IMPORTANT: Channel must have relay on, so if you didn't do that yet, run @relay-on

  1. Enable relay – by running @relay-on
  2. Insert a repository by running @github+ <full name of repo>
  3. Install a webhook (see screenshot below)

For every repository for which you wish to receive messages to your IRC channel, install a webhook to https://wm-bot.wmcloud.org/github/index.php (Libera) or https://wm-bot.wmflabs.org/github/index.php (freenode) in the settings of your repository. Make sure you set the content type to JSON, or it won't work.

Known issues: If you set up a token for channel relay, you will need to remove the repository and re-add it because tokens get added to the database only when a repository is inserted.


Requires trusted

Insert a repository full name into a database of your channel. If your repository is https://github.com/benapetr/test-100, then the full name is benapetr/test-100.

For this to work you also need to install webhook into GitHub, see above for how to do that.


Requires trusted

Removes a repository full name from the database, hooks for this repository will be silently ignored.

System admin[edit]

These commands are not useful for regular users


Require root rights

Restart the process of bot


Require admin rights

Requires root

@instance <instance> #<channel>

Changes default instance for a channel

Files and logs[edit]


The bot will talk any language you want in a specific channel. All you need to do, is ask admin of bot to say @language <code>

You can translate the bot to your language by creating a subpage, example Wm-bot/ru for Russian. Then just translate the default English file.

Supported languages are:

For developers[edit]


Source code is in git type

git clone https://github.com/benapetr/wikimedia-bot.git

to download it


In order to compile the bot, you need a C# compiler like GCS or Microsoft's CSC. Visual Studio or MonoDevelop are the recommended IDE's: they allow you to just open the project file and hit make.

This is a most simple way to build stuff on Debian:

# after you checkout the bot
cd wikimedia-bot

Setting up[edit]


  • When you build the bot for the first time, there should be a binary either in bin/debug or bin/Release (depends on if you directly invoke xbuild or use the make script). Pick one of these binaries.
  • Create a folder and optionally a Unix user which you will use to run the wm-bot under as a service
  • Copy the binary into root of that path, let's call it $wmibhome
  • Create folder $wmibhome/configuration
  • Create file $wmibhome/configuration/wmib.conf and put there following text
// This is a username for a bot
// This password is optional and bot will use it to auth with nickserv in case you provide it
// This is a root url that will be used in queries like @info
// Whether bot uses a bouncer or not
// Debug channel
// Irc server bot will connect to
// This is css style that will be used for dynamically created html pages
// This is interval that bot will send messages to network server to in milliseconds, lower the interval is
// faster the bot will send messages to server. Low interval may result in k-line on some networks.
// Nickname for primary instance
// Optional mysql username
// Optional mysql host
// Optional password
// Name of database to store items to (by default bot doesn't use mysql, but some extensions might want to)
  • chown this file to wm-bot user and change chmod to 600, this file is dynamically updated by a bot, never write to it when bot is running
  • create database of bot administrators in $wmibhome/configuration/admins example below
.*@wikimedia/Petrb|root|this is a secret password|root

These users will be globally recognized in any channel, first column is regular expression to match IRC hostname, second is user level, third is password for system console, fourth is username for system console

  • now you can launch the bot (mono wmib.exe)

Restarting the bot[edit]
