read-toml-py

A small utility to read keys from TOML files.

Usage

Installation

poetry add outcome-read-toml

Usage

The utility reads the value specified by the key from the provided TOML file, and prints it to stdout.

The path parameter should be a '.' separated sequences of keys that correspond to a path in the TOML structure.

Example TOML file:

title = "My TOML file"

[info]
version = "1.0.1"

[tools.poetry]
version = "1.1.2"
files = ['a.py', 'b.py']

Read standard keys:

read-toml --path my_file.toml --key title 
# "My TOML file"

read-toml --path my_file.toml --key info.version
# "1.0.1"

Read arrays:

read-toml --path my_file.toml --key tools.poetry.files
# "a.py b.py"

read-toml --path my_file.toml[0] --key tools.poetry.files
# "a.py"

You can't read non-leaf keys:

read_toml.py --path my_file.toml --key tools
# KeyError

You can check if a key exists:

read-toml --path my_file.toml --key title --check-only 
# 1

read-toml --path my_file.toml --key unknown_key --check-only
# 0
