🤖 Automating key workflows in your daily developer life!

In this talk, I want to guide the audience through the tools I implemented and the scripts I built over time in our CI system to automate common tasks like:
- Daily release deliveries to QA (releases run automatically only if there were any new commits since the last one)
- Automated Git(Hub) tags creation for each release
- Automated release notes included in the tags (for QA)
- Automated code formatting with standard rules automatically shared across all the members of a team

I currently work with Bitrise, which means my example may include that tool (but the scripts are tool agnostic).

5. 🤖 Automated Git(Hub) tags creation for each release
6. • Daily work fl ow • Check if there are any commits since the last available tag • If yes -> generate and push a new tag CI setup
7. Tag format: Beta_X E.g. Beta_1, Beta_2… Beta_123, etc Script - Check commits since last release
8. function get_latest_tag() { latestTag=$(git for-each-ref "refs/**/*Beta_[0-9]*" —sort=-creatordate --format='%(refname:short)' --count=1) } Script - Check commits since last release
9. function get_latest_tag_number() { # Gets beta number from format like "beta_100" latestTagNumber=${ADDR[1]} } Script - Check commits since last release
