Matterpoll is a plugin for Mattermost. It allows users to create poll by using a slash command.

Installation

1. Download com.github.matterpoll.matterpoll-x.y.z.tar.gz from https://github.com/matterpoll/matterpoll/releases.
2. Upload com.github.matterpoll.matterpoll-x.y.z.tar.gz file through System Console > Plugins > Plugin Management > Upload Plugin in Mattermost and enable the plugin.
   • Upgrades can be performed by uploading the lastest release and confirm overwriting of the duplicate plugin ID.

Settings

You can configure Matterpoll from System Console > Plugins > Matterpoll.

• Trigger Word: Change trigger word for poll command. (default /poll)
• Experimental UI: Enable new experimental UI for poll posts:
  • Change button color of voted answers
  • Hide poll management buttons (Add Option / Delete Poll / End Poll) from users who don't have permission
• Default Settings: Choose settings, that will be pre-selected in 'Create Poll' dialog. Settings will not be applied to /poll command.

Note: Experimental UI is not supported in Mattermost Mobile due to its limited support for plugin extension (ref).

Usage

/poll "Is Matterpoll great?" creates a poll with the answer options "Yes" and "No". You can also leave out the double quotes and just type /poll Is Matterpoll great?.

If you want to define all answer options by yourself, type /poll "Is Matterpoll great?" "Of course" "In any case" "Definitely"- Note that the double quotes are required in this case.

/poll show up a modal for creating a poll.

Poll Settings

Poll Settings provide further customisation, e.g. /poll "Is Matterpoll great?" "Of course" "In any case" "Definitely" --progress --anonymous. The available Poll Settings are:

• --anonymous: Don't show who voted for what at the end
• --progress: During the poll, show how many votes each answer option got and, in post card, show who voted for which answers (#431)
• --public-add-option: Allow all users to add additional options
• --votes=X: Allow users to vote for X options

Localization

Matterpoll supports localization of user specify messages. You can change language of poll message by setting it in System Console > Site Configuration > Localization > Default Server Language. Language of messages that only a user can see (e.g.: help messages, error messages) use the language set in Settings > Display > Language.

The currently supported languages are:

• English
• French
• German
• Japanese
• Korean
• Polish
• Russian
• Simplified Chinese
• Spanish
• Traditional Chinese

Troubleshooting

Pressing the poll buttons does nothing and creates a 400 error in the Mattermost log

Make sure to set your Site URL properly. For example, this error happens in case you set SiteURL starting with http://, in spite of running Mattermost server through https.

Plugin upload causes "Received invalid response from the server."

Ensure that the "Maximum File Size" (System Console > File Storage) is set to be larger than the com.github.matterpoll.matterpoll-x.y.z.tar.gz file.
