明らかな問題は、ブランチがハードコードされていることです。ブランチが現在表示されているものになるように、ある種の変数を使用することは可能ですか?
README.md の Travis 行を現在のブランチで書き換える git pre-commit フックを使用して、この問題を回避しました。使用例と事前コミット (Python) コード (質問に対する) を以下に示します。
dandye$ git checkout -b feature123 origin/master
Branch feature123 set up to track remote branch master from origin.
Switched to a new branch 'feature123'
dandye$ echo "* Feature123" >> README.md
dandye$ git add README.md
dandye$ git commit -m "Added Feature123"
