1) Via GUI: fork or clone at github so that you have URL to use in 2)
git clone giturl....
to fetch local instance
git checkout -b feature/new_thing_a
(this is 2. above by Inaki)
4) Edit, save, compile, test, revise, ... leading to 1 or more commits
git push origin
standard configuration should have remote branch follow local branch, I
think the "long form" is
git push --set-upstream origin feature/new_thing_a
git checkout -
git checkout master
and you are back in master. Now you can restart at my 3) above for
branches b, c, d and create independent pull requests
I find it really to have a bash prompt that shows the branch:
edd at rob:~$ cd git/rcpp
edd at rob:~/git/rcpp(master)$ git checkout -b feature/new_branch_to_show
Switched to a new branch 'feature/new_branch_to_show'
edd at rob:~/git/rcpp(feature/new_branch_to_show)$ git checkout -
Switched to branch 'master'
Your branch is up-to-date with 'origin/master'.
edd at rob:~/git/rcpp(master)$ git branch -d feature/new_branch_to_show
Deleted branch feature/new_branch_to_show (was 5b25fe62).
edd at rob:~/git/rcpp(master)$
There are few tutorials out there about how to do it, I once got mine from
Karthik when we did a Software Carpentry workshop. Happy to detail off-list,
it adds less than 10 lines to ~/.bashrc.
