name: Slack notification on pushes to releases/*
|
|
|
|
# This CI job will push notifications to Slack whenever code is merged into any releases/* branch
|
|
#
|
|
# The steps of the command line kung-fu shown below are as follows:
|
|
# First we take the JSON-formatted Github context
|
|
# echo $GITHUB_CONTEXT \
|
|
# Then we parse out the specific fields we want for our messages using jq and format it into tab-separated values
|
|
# | jq '.event.commits[] | [.url, .id[0:7], .author.username, .timestamp, .message] | @tsv' \
|
|
# We need to do some cleaning on this output - specifically removing quotes and replacing newlines with something easier to split
|
|
# | sed 's/"//g' | sed 's/\\t/;/g' | sed 's/\\n/;/g' | sed 's/\\//g' \
|
|
# We then use awk to format the TSV into a Slack message
|
|
# | awk -F';' '{print "• <"$1"|"$2"> (<https://github.com/"$3"|"$3">, "$4") - "$5}' \
|
|
# We need to deal with some escaping issues with newlines so that we don't break the Slack message format
|
|
# | sed 's/$/\\n/g' | tr -d '\n' \
|
|
# Finally we have to truncate the message to 3,000 characters max, otherwise Slack will reject it
|
|
# | awk '{print substr($0,0,3000);}' \
|
|
# Then shove the bytes into a file to store them in their exact format
|
|
# > /tmp/parsed_github_context
