maschine is a chat bot built on the Hubot framework. It was initially generated by generator-hubot.
Here's a link to the hubot docs for reference.
You can test maschine by running the following, however some plugins will not behave as expected unless the environment variables they rely upon have been set.
Start out by installing the dependencies through npm:
% npm install
maschine also stores stuff in redis, his brain. So go ahead and install that.
You can start maschine locally by running:
% bin/hubot
You'll see some start up output and a prompt:
[Sat Feb 28 2015 12:38:27 GMT+0000 (GMT)] INFO Using default redis on localhost:6379
maschine>
Then you can interact with maschine by typing maschine help
.
maschine> maschine help
maschine animate me <query> - The same thing as `image me`, except adds [snip]
maschine help - Displays all of the help commands that maschine knows about.

A few scripts (including some installed by default) require environment variables to be set as a simple form of configuration.
Each script should have a commented header which contains a "Configuration" section that explains which values it requires to be placed in which variable. When you have lots of scripts installed this process can be quite labour intensive. The following shell command can be used as a stop gap until an easier way to do this has been implemented.
grep -o 'hubot-[a-z0-9_-]\+' external-scripts.json | \
xargs -n1 -I {} sh -c 'sed -n "/^# Configuration/,/^#$/ s/^/{} /p" \
$(find node_modules/{}/ -name "*.coffee")' | \
awk -F '#' '{ printf "%-25s %s\n", $1, $2 }'
How to set environment variables will be specific to your operating system. Rather than recreate the various methods and best practices in achieving this, it's suggested that you search for a dedicated guide focused on your OS.
An example script is included at scripts/example.coffee
, so check it out to
get started, along with the Scripting Guide.
For many common tasks, there's a good chance someone has already one to do just the thing.
There will inevitably be functionality that everyone will want. Instead of writing it yourself, you can use existing plugins.
Hubot is able to load plugins from third-party npm
packages. This is the
recommended way to add functionality to your hubot. You can get a list of
available hubot plugins on npmjs.com or by using npm search
:
% npm search hubot-scripts panda
NAME DESCRIPTION AUTHOR DATE VERSION KEYWORDS
hubot-pandapanda a hubot script for panda responses =missu 2014-11-30 0.9.2 hubot hubot-scripts panda
...
To use a package, check the package's documentation, but in general it is:
- Use
npm install --save
to add the package topackage.json
and install it - Add the package name to
external-scripts.json
as a double quoted string
You can review external-scripts.json
to see what is included by default.
It is also possible to define external-scripts.json
as an object to
explicitly specify which scripts from a package should be included. The example
below, for example, will only activate two of the six available scripts inside
the hubot-fun
plugin, but all four of those in hubot-auto-deploy
.
{
"hubot-fun": [
"crazy",
"thanks"
],
"hubot-auto-deploy": "*"
}
Be aware that not all plugins support this usage and will typically fallback to including all scripts.
Before hubot plugin packages were adopted, most plugins were held in the hubot-scripts package. Some of these plugins have yet to be migrated to their own packages. They can still be used but the setup is a bit different.
To enable scripts from the hubot-scripts package, add the script name with
extension as a double quoted string to the hubot-scripts.json
file in this
repo.
If you are going to use the hubot-redis-brain
package (strongly suggested),
you will need to add the Redis to Go addon on Heroku which requires a verified
account or you can create an account at Redis to Go and manually
set the REDISTOGO_URL
variable.
% heroku config:add REDISTOGO_URL="..."
If you don't need any persistence feel free to remove the hubot-redis-brain
from external-scripts.json
and you don't need to worry about redis at all.
Adapters are the interface to the service you want your hubot to run on, such as Campfire or IRC. There are a number of third party adapters that the community have contributed. Check Hubot Adapters for the available ones.
If you would like to run a non-Campfire or shell adapter you will need to add
the adapter package as a dependency to the package.json
file in the
dependencies
section.
Once you've added the dependency with npm install --save
to install it you
can then run hubot with the adapter.
% bin/hubot -a <adapter>
Where <adapter>
is the name of your adapter without the hubot-
prefix.
