Scripts
An abstract type describing a marvin script.
This is basically a collection of event handlers.
Internal structure is exposed for people wanting to extend this.
defineScript :: ScriptId -> ScriptDefinition a () -> ScriptInit a Source #
Define a new script for marvin
You need to provide a ScriptId (which can simple be written as a non-empty string). This id is used as the key for the section in the bot config belonging to this script and in logging output.
Roughly equivalent to "module.exports" in hubot.
data ScriptInit a Source #
Initializer for a script. This gets run by the server during startup and creates a Script
A type, basically a String, which identifies a script to the config and the logging facilities.
data ScriptDefinition a r Source #
Reacting
hear :: Regex -> BotReacting a MessageReactionData () -> ScriptDefinition a () Source #
Whenever any message matches the provided regex this handler gets run.
Equivalent to "robot.hear" in hubot
respond :: Regex -> BotReacting a MessageReactionData () -> ScriptDefinition a () Source #
Runs the handler only if the bot was directly addressed.
Equivalent to "robot.respond" in hubot
customTrigger :: (Event -> Maybe d) -> BotReacting a d () -> ScriptDefinition a () Source #
send :: (IsAdapter a, HasMessage m) => String -> BotReacting a m () Source #
Send a message to the channel the triggering message came from.
Equivalent to "robot.send" in hubot
reply :: (IsAdapter a, HasMessage m) => String -> BotReacting a m () Source #
Send a message to the channel the original message came from and address the user that sent the original message.
Equivalent to "robot.reply" in hubot
messageChannel :: (AccessAdapter m, IsAdapter (AdapterT m), IsScript m, MonadIO m) => String -> String -> m () Source #
Send a message to a Channel (by name)
getData :: BotReacting a d d Source #
Obtain the event reaction data.
The type of this data depends on the reacion function used.
For instance hear
and respond
will contain MessageReactionData
.
The actual contents comes from the event itself and was put together by the trigger.
getMessage :: HasMessage m => BotReacting a m Message Source #
Get the message that triggered this action Includes sender, target channel, as well as the full, untruncated text of the original message
getMatch :: HasMatch m => BotReacting a m Match Source #
Get the results from matching the regular expression.
Equivalent to "msg.match" in hubot.
getUsername :: (AccessAdapter m, IsAdapter (AdapterT m), MonadIO m) => User -> m String Source #
Get the username of a registered user.
getChannelName :: (AccessAdapter m, IsAdapter (AdapterT m), MonadIO m) => Channel -> m String Source #
Get the human readable name of a channel.
getConfigVal :: (Configured a, HasConfigAccess m) => Name -> m (Maybe a) Source #
Get a value out of the config, returns Nothing
if the value didn't exist.
This config is the config for this script. Ergo all config vars registered under the config section for the ScriptId of this script.
The HasConfigAccess
Constraint means this function can be used both during script definition and when a handler is run.
requireConfigVal :: (Configured a, HasConfigAccess m) => Name -> m a Source #
Get a value out of the config and fail with an error if the specified key is not found.
This config is the config for this script. Ergo all config vars registered under the config section for the ScriptId of this script.
The HasConfigAccess
Constraint means this function can be used both during script definition and when a handler is run.
data BotReacting a d r Source #
Monad for reacting in the bot. Allows use of functions like send
, reply
and messageChannel
as well as any arbitrary IO
action using liftIO
.
The type parameter d
is the accessible data provided by the trigger for this action and can be obtained with getData
or other custom functions like getMessage
and getMatch
which typically depend on a particular type of data in d
.
For message handlers like hear
and respond
this would be a regex Match
and a Message
for instance.
For completeness: a
is the adapter type and r
is the return type of the monadic computation.
This is also a MonadReader
instance, there you can inspect the entire state of this reaction.
This is typically only used in internal or utility functions and not necessary for the user.
To inspect particular pieces of this state refer to the *Lenses* section.

.

Advanced actions
extractAction :: BotReacting a () o -> ScriptDefinition a (IO o) Source #
Take an action and produce an IO action with the same effect. Useful for creating actions which can be scheduled to execute a certain time or asynchronous. The idea is that one can conveniently send messages from inside a schedulable action.
extractReaction :: BotReacting a s o -> BotReacting a s (IO o) Source #
Take a reaction and produce an IO action with the same effect. Useful for creating actions which can be scheduled to execute a certain time or asynchronous. The idea is that one can conveniently send messages from inside a schedulable action.
