The secrets
of the Git
ninjas

 Every commit is a full snapshot.  

 no Deltas for fuck's sake 





 Let's Talk About Branches 

 A branch is just a name for a specific commit
 well almost





 Committed on the wrong branch?  

git branch featureBranch
git reset --hard HEAD~1





What the Head?!


"The HEAD is just a pointer to where your working directory should currently be on" --cburgdorf




How is that useful?




 git makes it hard to lose work

 As long as you ever had it COMMITTED 
Commit early, commit often 





 the reflog 


"The reflog is a history of all movements of the HEAD" --cburgdorf





 Pitfalls? 


commits that are not reachable by any branch/tag will be GC'ed after 30 days



 Demo 





 Commit early, Commit often 


 yet, nobody wants to read this 



 We want this 

 

 your coworkers will thank you! 



 Demo 



 ""I'll fix that later"" 

 as a workflow 


 4 commands: wip, ap, add -p, rebase -i 



 Demo 





 Cherry picking 


git cherry-pick sha4711

 git cherry-pick first~ .. last




 Avoid unnecessary Merge commits 





 Use a rebase workflow 

 

 Because 

 




 merging blindly means 

 - your history becomes a mess 
  - YOU hide information in merge commits 
 - harder to do git bisect 
  - HARDER TO DO cherry picking 




 make the console your friend 
 

git config --global alias.ca '!git add -A && git commit'

git config --global alias.lg '!git log --pretty=one-line --abbrev-commit --graph --decorate'

git config --global alias.wip '!git add -A && git commit -m "WIP"'

git config --global alias.ap '!git add -A && git commit --amend --no-edit'




 One more thing 





Thanks.
