mattermost-plugin-dice-roller

Maintainer: @moussetc

This Mattermost plugin adds a /roll slash command to roll all kinds of virtual dice.

Examples

• Use /roll help to show examples.
• Use /roll 20, /roll d20 or /roll 1D20 to roll a 20-sided die:

• Use /roll 5d6 to roll five 6-sided dice:

• Use /roll 5D6+3 to roll five 6-sided dice and add 3 to the result of each dice:

• Use /roll 5D6 +3 (note the space) to roll five 6-sided dice and add 3 to the total:

• Combine different dice to roll at the same time: /roll 5 d8 13D20 to roll one 5-sided die, one 8-sided die and thirteen 20-sided dice:

• [Up to version 3.0.x] Add sum at the end to sum results automatically: /roll 5 d8 13D20 sum. In later versions, the sum is always displayed without having to add sum.

Installation and configuration

Tip

This plugin was for a few years available in the official Mattermost marketplace, however the Mattermost team decided to stop hosting community plugins in the marketplace in September 2023, so however you installed your current version, you will need to follow the manual installation steps below.

1. Go to the Releases page and download the .tar.gz package. Supported platforms are: Linux x64, Windows x64, Darwin x64, FreeBSD x64.
2. Use the Mattermost System Console > Plugins Management > Management page to upload the .tar.gz package
3. Activate the plugin in the System Console > Plugins Management > Management page

Configuration Notes in HA

If you are running Mattermost v5.11 or earlier in High Availability mode, please review the following:

1. To install the plugin, use these documented steps
2. Then, modify the config.json using the standard doc steps to the following:

 "PluginSettings": {
        // [...]
        "Plugins": {
            "com.github.moussetc.mattermost.plugin.diceroller": {
            },
        },
        "PluginStates": {
            // [...]
            "com.github.moussetc.mattermost.plugin.diceroller": {
                "Enable": true
            },
        }
    }

Development

to build the plugin:

make

This will produce a single plugin file (with support for multiple architectures) for upload to your Mattermost server:

dist/com.example.my-plugin.tar.gz

Deploying with Local Mode

If your Mattermost server is running locally, you can enable local mode to streamline deploying your plugin. Edit your server configuration as follows:

{
    "ServiceSettings": {
        ...
        "EnableLocalMode": true,
        "LocalModeSocketLocation": "/var/tmp/mattermost_local.socket"
    },
}

and then deploy your plugin:

make deploy

You may also customize the Unix socket path:

export MM_LOCALSOCKETPATH=/var/tmp/alternate_local.socket
make deploy

If developing a plugin with a webapp, watch for changes and deploy those automatically:

export MM_SERVICESETTINGS_SITEURL=http://localhost:8065
export MM_ADMIN_TOKEN=j44acwd8obn78cdcx7koid4jkr
make watch

Deploying with credentials

Alternatively, you can authenticate with the server's API with credentials:

export MM_SERVICESETTINGS_SITEURL=http://localhost:8065
export MM_ADMIN_USERNAME=admin
export MM_ADMIN_PASSWORD=password
make deploy

or with a personal access token:

export MM_SERVICESETTINGS_SITEURL=http://localhost:8065
export MM_ADMIN_TOKEN=j44acwd8obn78cdcx7koid4jkr
make deploy
