# Processes slack-formatted text messages, as Mattermost does with
|
|
# Slack incoming webhook interoperability, for example links in the
|
|
# format <LINK> and <LINK|TEXT>, <!here> and <!all> mentions.
|
|
#
|
|
# See https://api.slack.com/reference/surfaces/formatting for all of
|
|
# the different formatting slack supports with mrkdwn which is mostly
|
|
# identical to Markdown.

# Mattermost docs for translating the slack format:

# We may want to process attachments and blocks from slack in future, and
|
|
# convert user IDs into user mentions.
