## Output Formatting

### JSON Output

```bash
# Basic JSON
gh repo view --json name,description

# Nested fields
gh repo view --json owner,name --jq '.owner.login + "/" + .name'

# Array operations
gh pr list --json number,title --jq '.[] | select(.number > 100)'

# Complex queries
gh issue list --json number,title,labels \
  --jq '.[] | {number, title: .title, tags: [.labels[].name]}'
```

### Template Output

```bash
# Custom template
gh repo view \
  --template '{{.name}}: {{.description}}'

# Multiline template
gh pr view 123 \
  --template 'Title: {{.title}}
Author: {{.author.login}}
State: {{.state}}
'
```

## Common Workflows

### Create PR from Issue

```bash
# Create branch from issue
gh issue develop 123 --branch feature/issue-123

# Make changes, commit, push
git add .
git commit -m "Fix issue #123"
git push

# Create PR linking to issue
gh pr create --title "Fix #123" --body "Closes #123"
```

### Bulk Operations

```bash
# Close multiple issues
gh issue list --search "label:stale" \
  --json number \
  --jq '.[].number' | \
  xargs -I {} gh issue close {} --comment "Closing as stale"

# Add label to multiple PRs
gh pr list --search "review:required" \
  --json number \
  --jq '.[].number' | \
  xargs -I {} gh pr edit {} --add-label needs-review
```

### Repository Setup Workflow

```bash
# Create repository with initial setup
gh repo create my-project --public \
  --description "My awesome project" \
  --clone \
  --gitignore python \
  --license mit

cd my-project

# Set up branches
git checkout -b develop
git push -u origin develop

# Create labels
gh label create bug --color "d73a4a" --description "Bug report"
gh label create enhancement --color "a2eeef" --description "Feature request"
gh label create documentation --color "0075ca" --description "Documentation"
```

### CI/CD Workflow

```bash
# Run workflow and wait
RUN_ID=$(gh workflow run ci.yml --ref main --jq '.databaseId')

# Watch the run
gh run watch "$RUN_ID"

# Download artifacts on completion
gh run download "$RUN_ID" --dir ./artifacts
```

### Fork Sync Workflow

```bash
# Fork repository
gh repo fork original/repo --clone

cd repo

# Add upstream remote
git remote add upstream https://github.com/original/repo.git

# Sync fork
gh repo sync

# Or manual sync
git fetch upstream
git checkout main
git merge upstream/main
git push origin main
```

## Environment Setup

### Shell Integration

```bash
# Add to ~/.bashrc or ~/.zshrc
eval "$(gh completion -s bash)"  # or zsh/fish

# Create useful aliases
alias gs='gh status'
alias gpr='gh pr view --web'
alias gir='gh issue view --web'
alias gco='gh pr checkout'
```

### Git Configuration

```bash
# Use gh as credential helper
gh auth setup-git

# Set gh as default for repo operations
git config --global credential.helper 'gh !gh auth setup-git'

# Or manually
git config --global credential.helper github
```

## Best Practices

1. **Authentication**: Use environment variables for automation

   ```bash
   export GH_TOKEN=$(gh auth token)
   ```

2. **Default Repository**: Set default to avoid repetition

   ```bash
   gh repo set-default owner/repo
   ```

3. **JSON Parsing**: Use jq for complex data extraction

   ```bash
   gh pr list --json number,title --jq '.[] | select(.title | contains("fix"))'
   ```

4. **Pagination**: Use --paginate for large result sets

   ```bash
   gh issue list --state all --paginate
   ```

5. **Caching**: Use cache control for frequently accessed data
   ```bash
   gh api /user --cache force
   ```

## Getting Help

```bash
# General help
gh --help

# Command help
gh pr --help
gh issue create --help

# Help topics
gh help formatting
gh help environment
gh help exit-codes
gh help accessibility
```
