New git commands: git switch & git restore!

For a long time, I was working with SVN as my default version control system. I liked it a lot for its clear syntax.

When I switched to the git, I was surprised how overloaded the checkout sub-command really is:

— You need to switch to another branch? Use git checkout.

— You need to revert modifications made to files? Use git checkout.

In SVN you have separate commands for each of these tasks.

Starting with git 2.23 we have new sub-commands to address this:

  • git switch to switch between branches
  • git restore to undo all modifications made

I'm sure this new syntax will be a great help for newcomers from SVN. Consider this new workflow. Extremely clear to me!

$ git switch docker-tests
Switched to branch 'docker-tests'
Your branch is up to date with 'origin/docker-tests'.

$ git status
On branch docker-tests
Your branch is up to date with 'origin/docker-tests'.

Changes not staged for commit:
  (use "git add/rm <file>..." to update what will be committed)
  (use "git restore <file>..." to discard changes in working directory)
        deleted:    README.md

no changes added to commit (use "git add" and/or "git commit -a")

nothing to commit, working tree clean

`diff.orderFile`: order your `git diff` output smart!

Working on a project, you might consider that one folder is more important than others. For example, src folder might be more relevant to you as a developer than doc, test, or samples, you name it. Or you may want source files to be listed first, e.g. *.c, *.go...

To order the list of files in git diff output, one may use git's diff.orderFile option.

If you are working with PostgreSQL for example, you may want such an order:

src/include/* 
src/common/* 
src/port/* 
config/* 
src/makefiles/* 
src/template/* 
src/backend/* 
src/fe_utils/* 
src/bin/* 
src/interfaces/libpq/* 
src/pl/* 
contrib/* 
src/interfaces/* 
doc/* 
src/test/*

To achieve this:

  • create a file with the proper list, e.g. .gitorderfile
  • run git config diff.orderFile .gitorderfile

You're done!
