🔧 Advanced Git Changelog Alias

Generate clean, conventional changelogs from your current branch vs master, with optional --author and --name flags.

---

📋 Add the alias

git config --global alias.changelog '!f() { author=""; show_name="false"; while [ $# -gt 0 ]; do case "$1" in --author) author="--author=$2"; shift 2 ;; --name) show_name="true"; shift ;; *) break ;; esac; done; if [ "$show_name" = "true" ]; then git log master..HEAD --pretty=format:"- %s (@%an) (%h)" --no-merges --first-parent $author --grep="^feat\\|^fix\\|^docs\\|^style\\|^refactor\\|^perf\\|^test\\|^chore"; else git log master..HEAD --pretty=format:"- %s (%h)" --no-merges --first-parent $author --grep="^feat\\|^fix\\|^docs\\|^style\\|^refactor\\|^perf\\|^test\\|^chore"; fi; }; f'

📝 What it does

• Compares current branch with master.

• Filters for conventional commit types:

  • feat, fix, docs, style, refactor, perf, test, chore

• Supports:

  • --author "Name" — filter by author.
  • --name — append Git author username (as @Name).

• Excludes merge commits.

• Uses only first-parent commits.

---

▶️ Usage

Basic changelog:

git changelog

Filter by author:

git changelog --author "Alice"

Include author Git name (e.g., @Alice):

git changelog --name

Combine both:

git changelog --author "Alice" --name
