# How does it work:
2021-01-25 01:20:51 +03:00
#
2021-06-24 16:30:05 +03:00
# 1. Cherry pick the latest commit from default branch
# to the target release branch if the target release branch already existed.
#
# 2. Bump latest version number to the following files:
#
2021-04-12 08:15:14 +03:00
# - _sass/jekyll-theme-chirpy.scss
2021-04-19 09:51:45 +03:00
# - _javascript/copyright
2021-04-12 08:15:14 +03:00
# - assets/js/dist/*.js (will be built by gulp later)
# - jekyll-theme-chirpy.gemspec
# - package.json
#
2021-06-24 16:30:05 +03:00
# 3. Create a git-tag on release branch
2021-04-12 08:15:14 +03:00
#
2021-06-24 16:30:05 +03:00
# 4. Build a RubyGems package base on the latest git-tag
2021-04-12 08:15:14 +03:00
#
#
# Usage:
#
2021-06-24 16:30:05 +03:00
# Run on default branch, if run on other branch requires parameter '-m' (manual mode).
#
#
2021-02-10 12:53:25 +03:00
# Requires: Git, Gulp, RubyGems
