Git your own adventure
You are in a stretch dark corridor where you have learned the very basics of control versioning with git. You feel powerful but a little tired.
There's a branch a few metters before you in the corridor, you can:
- go here for learning to branch
- keep reading for learning to manage remote
Remote
We don't need github
github?
github is for git,
as
wordpress, for html
edit,
publish
& share
octocat
> git remote add
git remote
> git pull
... commit, commit, commit, commit, ...
> git push
push permissions
do you trust devs?
let it be pulled
Branches
> git branch
A branch is a pointer
> git branch <new>
> git checkout <new>
some work, commit, commit, ...
branch pointer moves with commits
Basic branching
> git branch feature1
> git checkout feature1
work, commit, commit, ...
Achtung! Alarm!
> git checkout master
> git branch hotfix
> git checkout hotfix
work, commit, commit, ...
> git checkout master
> git merge hotfix
beer!
> git checkout feature1
... keep working
> git checkout master
> git merge feature1
Conflict!
> git merge smth
Fail to merge!
