Marvin, the paranoid bot (β stage)

Travis Hackage

Marvin is an attempt to combine the ease of use of hubot with the typesafety and easy syntax of Haskell and the performance gains from compiled languages.

Installing and using marvin

The verbose documentation can be found on readthedocs https://marvin.readthedocs.io. It should hopefully answer all your questions.

Installation instructions are on this documentation page.


A teaser

module MyScript where

import Marvin.Prelude

script :: (IsAdapter a, SupportsFiles a) => ScriptInit a
script = defineScript "my-script" $ do
    hear "sudo (.+)" $ do
        match <- getMatch

        reply $(isL "All right, i'll do #{match !! 1}")

    respond "repeat" $ do
        message <- getMessage

        send $(isL "You wrote #{message}")

    respond "what is in file ([\\w\\._/-]+)\\??" $ do
        match <- getMatch 
        let file = match !! 1

        contents <- liftIO $ readFile file

        send contents

    respond "upload file ([\\w\\._/-]+)" $ do
        [_, filepath] <- getMatch
        chan <- getChannel
        f <- sendFile filepath
        case res of
            Left err -> send $(isL "Failed to share file: #{err}")
            Right _  -> send "File successfully uploaded"

    enterIn "random" $ do
        user <- getUser
        send $(isL "Hello #{user^.username} welcome to the random channel!")

    fileSharedIn "announcements" $ do
        file <- getFile
        safeFileToDir file "shared-files"

Testing and Talking

There's a slack channel where you can ask questions or play around with a test instance of marvin.

It's currently invite-only, so send me an email if you would like to join.

Status of the project

I try to respond to issues and I am happy to review and merge pull requests. I have some more features planned but I don't yet know when I'll get the time to implement them.

Maintenance Level: Happy to merge

Accepting maintainers: Yes

For information on the meaning of this see commercialhaskell guide to OSS maintenance

Issues and errors

If you are a marvin user, please report any error, issues, or improvement suggestions to the issue section or write me an email.


I welcome anybody who tests marvin by deploying it. Especially testing different adapters is a huge help.


If you want to hack on marvin, feel free to do so and send me your changes as pull requests.

Current hot places to get started:

  • Convenient HTTP requests API in Marvin.Util.HTTP.
  • Convenient JSON handling API in Marvin.Util.JSON.
  • New adapters as submodules of Marvin.Adapter.
  • A basic library of scripts (maybe as a Marvin.Scripts.Prelude module?) (inspiration: https://github.com/github/hubot-scripts)
