python-cuddle

A Python library for the KDL Document Language.

Install

pip install cuddle

Cuddle supports Python 3.9 and above.

Usage

from cuddle import parse, Document, Node
print(parse('''// Nodes can be separated into multiple lines
title \
  "Some title"

// Nested nodes are fully supported
contents {
  section "First section" {
    paragraph "This is the first paragraph"
    paragraph "This is the second paragraph"
  }
}

// Files must be utf8 encoded!
smile "😁"

// Instead of anonymous nodes, nodes and properties can be wrapped
// in "" for arbitrary node names.
"!@#$@$%Q#$%~@!40" "1.2.3" "!!!!!"=true

// The following is a legal bare identifier:
foo123~!@#$%^&*.:'|/?+ "weeee"

// And you can also use unicode!
ノード　お名前="☜(ﾟヮﾟ☜)"

// kdl specifically allows properties and values to be
// interspersed with each other, much like CLI commands.
foo bar=true "baz" quux=false 1 2 3
'''))

# Creating documents from scratch is currently very gross
print()
doc = Document()
doc.append(Node(name='simple-name', properties=None, arguments=[123], children=[Node(name='complex name here!', properties=None, arguments=None, children=None)]))
print(doc)

title "Some title"
smile "😁"
!@#$@$%Q#$%~@!40 !!!!!=true "1.2.3"
foo123~!@#$%^&*.:'|/?+ "weeee"
ノード お名前="☜(ﾟヮﾟ☜)"
foo bar=true quux=false "baz" 1 2 3

simple-name 123 {
        "complex name here!"
}
