Here is my own DSL. Interesting that it turns out we have similar aliases...
alias ga='git add'
alias gb='git branch'
alias gbD='gb -D '
alias gbc='gc -b '
alias gbd='gb -d '
alias gc='git checkout'
alias gcm='git checkout master'
alias gd='git diff '
alias gdd='gd --cached'
alias gdm='gd master...'
alias ge='git grep -InE '
alias gec='git branch --remotes --contains '
alias geh='git log --all --oneline --decorate -G '
alias gei='ge -i'
alias gff='gh && gpr && gr && ghp'
alias gfm='b=$(gw) && [[ "$b" != master ]] && gcm && gpr && gfu && gr && gc $b && unset b'
alias gfr='git fetch && git rebase origin/master'
alias gfu='git fetch upstream && git merge upstream/$(gw)'
alias gh='git stash'
alias gha='gh -k'
alias ghp='gh pop'
alias ghs='gh show -p '
alias gl='git log --graph --decorate --all'
alias gll='gl --pretty=format:"%C(yellow)%h %Cred%ad %Cblue%an%Cgreen%d %Creset%s" --relative-date'
alias glll='gl --color --graph --pretty=format:'\''%Cred%h%Creset -%C(yellow)%d%Creset %s %Cgreen(%cr)%C(bold blue)<%an>%Creset'\'' --abbrev-commit'
alias gp='git pull '
alias gpr='git pull origin $(gw)'
alias gps='git push'
alias gpt='gps --tags'
alias gr='git push origin $(gw)'
alias grr='git rebase -i HEAD~$(grrr | wc -l)'
alias grrr='git rev-list master..'
alias grt='gr --tags'
alias gs='git status'
alias gss='git show'
alias gu='git config --get remote.origin.url'
alias gv='git describe --abbrev --dirty --always --tags'
alias gw='git rev-parse --abbrev-ref HEAD 2>/dev/null'
alias gx='git archive --format tar --remote '
If shell aliases don't tab-complete for you, you can get tab completion just by defining git aliases instead. One extra space if you also alias g=git. And it solves namespacing.
I don't know if it's the same in bash, but at least in zsh, "git branch <TAB>" and "b <TAB>" have the exact same result, if b is aliased to "git branch"; the first tab fills in the name of the branch, another lets me select a commit, and further tabs are command line options.
