dotcat: Catting Structured Data in Style

Dealing with structured data in shell scripts is all but impossible. dotcat gives you the ability to fetch structured data as easily as using cat it.

# Access data by attribute path
dotcat data.json person.name.first
# John
dotcat data.json person.name.last
# Doe

# Controle your output format
dotcat data.json person.name --output=yaml
# name:
#   first: John
#   last: Doe
dotcat data.json person.name --output=json
# {"first": "John", "last": "Doe"}

# List access
dotcat data.json person.friends@0
# {"name":{"first": "Alice", "last": "Smith"}, "age": 25} -> item access
dotcat data.json person.friends@2:4
# [{"name":{"first": "Alice", "last": "Smith"}, "age": 25}, {"name":{"first": "Bob", "last": "Johnson"}, "age": 30}]  -> slice access
dotcat data.json person.friends@4:-1
# ... from 5th to last item

The good times are here

Easily read values from JSON, YAML, TOML, and INI files without complex scripting or manual parsing.

Access deeply nested values using intuitive dot-separated paths (e.g., person.first.name) while controlling the output format with --output flag.

Dotcat is a good unix citizen with well structured exit codes so it can take part of your command pipeline like cat or grep would.

Installation

If you have a global pip install, this will install dotcat globally:

pip install dotcat
