Config

git config merge.conflictstyle diff3
git config diff.wsErrorHighlight all
git config push.autoSetupRemote true

• merge.conflictstyle diff3 adds original code to the diff view, this helps arrive at correct resolution when resolving a conflict
• diff.wsErrorHighlight all Displays whitespace in diff
• push.autoSetupRemote true automates the first push of a branch

Aliases

I feel at home with these aliases. Run git config --global --edit and paste these under [alias] section:

        st = "status --short"
        last = "log --stat -1 HEAD"
        ls = "log --pretty=format:'%Cgreen %H %Creset%cr%Cred by %cn%Creset%n%s%n' --stat --graph"
        branches = "branch -avv  --sort=-committerdate"
        please = "push --force-with-lease"
        diffs = "diff -z --cached --color-moved"
        diffl = "diff  --color-moved HEAD~ HEAD"
        put = "!git add .; git commit -m"
        d = "!git diff -z  --color-moved --unified=0 && echo 'Summary:' && git status --short"

on Windows, use these variants. They lack unix’s && which runs second command only if first succeeded.

put = "!git add .; git commit -m"
d = "!git diff -z  --color-moved --unified=0; echo 'Summary:'; git status --short"

The only thing to watch out for is that speedy git put eagerly commits all changes in the working tree, including any unexpected or overlooked changes.

Line endings

On Windows, convert CRLF to LF on commit, and LF to CRLF on checkout: bash

git config --global core.autocrlf true

On Linux, convert CRLF to LF on commit only, to fix any CLRF line endings: bash

git config --global core.autocrlf input

Prompt summary

On Windows, use PoshGit to provide tab-completion and show status summary in the terminal.

Tips

Miscellaneous notes.

Transition changes to my fork

git remote set-url origin <fork URL>
git fetch --all -p

To ignore a change to the file, and then undo it

git update-index --skip-worktree .gitignore
git update-index --no-skip-worktree .gitignore

To list all conflicts

git diff --name-only --diff-filter=U

Occasional manual cleanup (tip: run it on schedule)

git gc
git prune
git gc --aggressive
