For better or worse, Plugins are just packages with a func Create(bot *core.Gobot)
method. There is no interface
you should be defining. Within
that create method, a plugin is allowed to do anything it likes to the bot.
Check out the Gobot type for things you can do to your 'bot.
For example, this plugin inserts BEES into your IRC channel everytime someone types the word "bees" (or "beeeees" or "beeeeeeeeees" and so on).
# plugin/bees/bees.go
package bees
import (
"github.com/collinvandyck/gesture/core"
)
func Create(bot *core.Gobot, config map[string]interface{}){
bot.ListenFor("bee(e*)s", func(msg core.Message, matches []string) error {
msg.Send("http://i.imgur.com/qrLEV.gif")
return nil
})
}
Gesture uses the following struct for configuration:
type Config struct {
DisableFloodProtection bool
BotName string
Hostname string
SSL bool
Channels []string
Plugins map[string]map[string]interface{}
}
Plugin configuration deserves a special mention. Plugin configuration is a map
of plugin names to plugin configuration maps. A plugin defines what it expects
out of a plugin configuration map (since it's a map[string]interface{}
, feel
free to do whatever you please!).
Gesture comes loaded with a build_bot
tool that generates an IRC-bot script
for you based on the same JSON configuration file that your bot will load.
Install it with
go install github.com/collinvandyck/gesture/build_bot
build_bot
expects that your plugin names will be the full import path of the
plugin package, and will generate you a script that includes all of the plugins
listed in your configuration. Unfortunately, even plugins that don't need to be
configured should be listed.
An example configuration that you want to use build_bot
on might look like:
{
"botname": "gesture",
"hostname": "irc.freenode.net",
"ssl": true,
"channels": ["#lolgesture"],
"plugins": {
"github.com/collinvandyck/gesture/plugin/gis": {},
"github.com/collinvandyck/gesture/plugin/graphite": {
"prefix": "myprefix"
},
"github.com/collinvandyck/gesture/plugin/youtube": {
"results": 3
},
"code.google.com/p/potato_chips_for_golang": {
"flavor": "salt_and_vinegar"
}
}
}
build_bot
dumps it's results to standard output and leaves you to
save that to a file and modify it however you please. When you're ready to run
your bot, go build
or go run
it the usual way.
NOTE: build_bot
does no validation of your config file because you have to
run it through the Go compiler yourself. If something's up with the output of
build_bot
, check that you have the proper packages listed as the names of your
plugins.
The build_bot
script uses Go templates to do it's magic. Check out the script
for more detail on how to construct a template.
Please also feel free to ignore build_bot
and write your own Gesture script!
