Generate git branch based on Jira tasks

auto-generate-git-branch-from-jira.md

Required:

• fzf: https://github.com/junegunn/fzf
• Jira CLI: https://github.com/ankitpokhrel/jira-cli

Setup:

1. Install Jira CLI, generate the API token and follow the initiation process. Make sure you can see a list of issues by using jira issue list.
2. Install fzf and setup some default configs if you like.
3. Put this code below into your .zshrc (I'm not sure about .bashrc, did not test it.

_fzf_complete_git() {
  ARGS="$@"
  CODE="$(echo $ARGS | sed 's/git checkout -b //g')"

  if [[ $CODE == "" ]]; then
    ME="-a$(jira me)"
    PROJECT_QUERY="AND project IS NOT EMPTY"
  else
    ME=""
    PROJECT_QUERY="AND project IN ($CODE)"
  fi

  local tasks
  tasks=$(jira issue list --plain --no-headers --columns key,summary $ME -q "status NOT IN (Done, Dismissed, Released, 'In Progress', 'Ready for release') $PROJECT_QUERY")
  if [[ $ARGS == 'git checkout -b'* ]]; then
    _fzf_complete --ansi --reverse --multi --prompt="fzf> " -- "git checkout -b " < <(
      echo $tasks | sed 's/[[:space:]]/-/g' | tr -dc '[:alnum:]-\n'
    )
  fi
}

4. Source the .zshrc and you can use.

Usage:

• Type the git command: git checkout -b CODE ** then press Tab.
• The CODE is the prefix of your ticket code. Usually they are in format ABC-123.
• If the CODE is omitted, it will try to search only tasks assigned to you.
• If you already changed your trigger to ~~, replace ** with ~~.
