dotcat: Catting Structured Data in Style

dotcat gives your shell the ability to cat + grep structured data.

# With a sample json file:
echo '{"name": "John Doe", "age": 30, "address": {"street": "123 Main St", "city": "Anytown"}}' > data.json

# Get the name
dotcat data.json name
# Output: John Doe

# Get the city
dotcat data.json address.city
# Output: Anytown

# Format the output
dotcat data.json address --format=yaml
# Output:
# street: 123 Main St
# city:
#   Anytown

# Use with a YAML file (data.yaml)
echo 'name: Jane Doe\noccupation: Developer' > data.yaml
dotcat data.yaml occupation
# Output: Developer

# Use array index in path (array.json)
echo '{"items":[{"id":1}, {"id":2}]}' > array.json
dotcat array.json items.1.id
# Output: 2
