yetibot
1.0.0
A chat bot written in Clojure, at your service.
You can think of Yetibot as a communal command line. It excels at:
Features that make Yetibot powerful and great, which is to say fun:
Take a look at the usage examples to
see some fun useful things it can do.

Welcome new contributors!
good first issue
are good for first time Yetibot contributors@devth for help on Slack, GitHub or
anywhere else you can find himGet an invite to the official Yetibot slack at slack.yetibot.com. There's Yetibot running on a Droplet generously provided by DigitalOcean that you can play with in Slack.
To quickly try out Yetibot with minimal config:

See CONTRIBUTING.
Yetibot has been undergoing continuous improvement since its inception. These are the immediate priorities, in addition to any bug fixes. Feedback and contributions are very welcome!
#yetibot channel or join Yetibot Slack!There are a few ways to run Yetibot:
Follow the Docker instructions: the fastest way if you're already using Docker.
yetibot-helm: the official Helm Chart for quickly running Yetibot on Kubernetes.
Clone this repo: this gives you a standard Yetibot installation and
provides a git-ignored place to store configuration. Run from the root dir
with lein run.
Make your own repo and depend on Yetibot: this gives you ultimate customizability, allowing you to depend on custom Yetibot plugins or define your own commands in-project, and gives you control over where you store your config (manual management, commit to private git repo, etc...)
See Configuration docs.
For more docs see the User Guide.
All commands are prefixed by !.
Output from one command can be piped to another, like Unix pipes.
!complete does IE support | xargs echo %s? No, it is sucky.
does ie support html5? No, it is sucky.
does ie support css3? No, it is sucky.
does ie support svg? No, it is sucky.
does ie support media queries? No, it is sucky.
does ie support ftps? No, it is sucky.
does ie support png? No, it is sucky.
does ie support canvas? No, it is sucky.
does ie support @font-face? No, it is sucky.
does ie support webgl? No, it is sucky.
does ie support ttf? No, it is sucky.
Backticks provide a lightweight syntax for sub-expressions, but they can't be nested.
!meme grumpy cat: `catfact` / False
For arbitrarily-nested sub-expressions, use $(expr) syntax, which
disambiguates the open and closing of an expressions.
!meme philos: $(complete how does one $(users | random | letters | random) | random)
!echo `repeat 4 echo i don't always repeat myself but | unwords`…StackOverflowError | meme interesting:
You can build your own aliases at runtime. These are stored in the configured database, so upon restart they are restored.
!alias nogrid = repeat 3 echo `repeat 3 meme grumpy: no | join`
Pipes can be used, but the right-hand side must be quoted in order to treat it as a literal instead of being evaluated according to normal pipe behavior.
!alias i5 = "random | echo http://icons.wunderground.com/webcamramdisk/w/a/wadot/324/current.jpg?t=%s&.jpg"
You can specify placeholder arguments on the right-hand side using $s to
indicate all arguments, or $n (where n is a 1-based index of which arg).
!alias temp = "weather $s | head 2 | tail"
!temp 98104
=> 33.6 F (0.9 C), Overcast
IRC: Yetibot can listen on any number of channels. You configure
channels in
config.edn.
You can also invite Yetibot to a channel at runtime using the IRC /invite
command:
/invite yetibot #whoa
When you invite Yetibot to a new channel, config.edn is overwritten, so next
time you restart Yetibot, it will re-join the same channels.
You can also use the !room command to tell yetibot to join or leave a channel.
!help room
room join # join
room leave # leave
room list # list rooms that yetibot is in
room set # configure a setting for the current room
room settings # show all chat settings for this room
room settings # show the value for a single setting
Slack: bots can't join a channel on their own, they must be invited, so
room configuration doesn't apply. Instead, /invite @yetibot to any channel
that you're in, and /kick @yetibot if you want it to leave. NB: you might need
special privileges in order to kick.
Campfire is no longer supported. If you use Campfire, open an issue and we can add it back in!
Other chat platforms: If your chat platform of choice is not supported, open an issue. Adding adapters is quite easy.
If a room has broadcast set to true, Tweets will be posted to that room.
By default all rooms have it set to false. To enable:
!room set broadcast true
Yetibot self-documents itself using the docstrings of its various commands. Ask it
for !help to get a list of help topics. !help all shows fully expanded command
list for each topic.

Yetibot has a plugin-based architecture. Its core which all plugins depend on is yetibot.core.
Yetibot will load all commands and observers with namespaces on the classpath matching these regexes.
This lets you build any number of independent plugin projects and combine them via standard Leiningen dependencies.
Curious how the internals of Yetibot works? At a high level:
hooked
into the interpreter's handle-cmd function using a cmd-hook macro and
triggered via regex prefix matchingIf the docs or implementation code don't serve you well, please open a pull request and explain why so we can improve the docs. Also feel free to open an issue for feature requests!
