When I notify alert to slack, I want to use this option.

Hi.
Thank you for your effort.

I use Alertmanager with Slack.
When I received messages, I wanna use this option for slack.

link_names

You can check this option what is.

https://api.slack.com/methods/chat.postMessage

I updated some codes a little bit.

Usage

slack_configs: 
   link_names: true

I think this options is so important for alerting.
I think most people want to notify them to their owners when they receive messages on Slack.

Thanks.

Thanks for the PR! I left a question above.

[9to6]

Hi. Where is a question?

[stuartnelson3]

Sorry about that! Must have disappeared somehow. Is link_names a string or a bool? From the documentation it looks like it might be a bool?

[9to6]

This option's default value is false.
When I use this option, I can input value, number 0 or 1, boolean true or false,
but when I test this option, It cannot allow "false", type is String
When this option set the value, string value "false", I think this option is regarded set True.

[stuartnelson3]

In that case, can you change the type to boolean? It probably interprets any string value as truthy.

[9to6]

I changed type to bool.
But I included invalid commit log inadvertently.

@9to6 Thank you very much for your contribution! Can you create a new branch right off of master and cherry-pick your two commits onto it?

Something along the lines of: (No guarantee, please backup your changes before)

git checkout master
git pull upstream master
git checkout -b slack_mention2
git cherry-pick fc2ab29b6dee17f7612958345c1d22e5d311eaab
git cherry-pick 18041521610b56f6f4eed39024d56a27ec1c967b
git push <your github repo alias> slack_mention2:slack_mention -f
