Zsh function to get issue number

git

current_branch() {
  git_branch=`git branch --no-color 2> /dev/null | sed -e '/^[^*]/d' -e 's/* \(.*\)/\1/'`
  if [ $git_branch ]; then
    echo "$git_branch"
  fi
}

gitissue() {
  github_issue=`echo $(current_branch) | sed  -e 's/\([0-9]*\).*/\1/'`
  if [ $github_issue ]; then
    echo "$github_issue"
  fi
}

pull_request() {
        local organization

        if [ ! $1 ]; then
                organization=`git config --get remote.origin.url | sed "s/^[^:]*:\([^\/]*\)\/.*/\1/"`
        else
                organization=$1
        fi    
              
        echo "hub pull-request -i $(gitissue) -b $organization:master -h $organization:$(current_branch)"
        `hub pull-request -i $(gitissue) -b $organization:master -h $organization:$(current_branch)`
}

alias pr="pull_request"
alias prj="pull_request jetthoughts"
alias prbb="pull_request bigbinnary"

than I use to send pull request to github: hub pull-request -i $(gitissue) -b bigbinary:master -h bigbinary:$(gitbranch)
