| |coverage| |master_build|

Pure python module for (de)serialization to and from VDF that works just like json.

A fork of ValvePython/vdf <https://github.com/ValvePython/vdf>_, which has apparently been abandoned.

Supports Python 3.6+ and PyPy 3.10

VDF is Valve's KeyValue text file format

| Supported versions: kv1 | Unsupported: kv2 and kv3

Install

WARNING: Only ValvePython's (out of date) version is on PyPI.

Installing directly from github repository:

.. code:: bash

# master
pip install "git+https://github.com/solsticegamestudios/vdf"

# specific version
pip install "git+https://github.com/solsticegamestudios/vdf@v1.0"

Problems & solutions

Example usage

For text representation

.. code:: python

import vdf

# parsing vdf from file or string
d = vdf.load(open('file.txt'))
d = vdf.loads(vdf_text)
d = vdf.parse(open('file.txt'))
d = vdf.parse(vdf_text)

# dumping dict as vdf to string
vdf_text = vdf.dumps(d)
indented_vdf = vdf.dumps(d, pretty=True)

# dumping dict as vdf to file
vdf.dump(d, open('file2.txt','w'), pretty=True)

For binary representation

.. code:: python

d = vdf.binary_loads(vdf_bytes)
b = vdf.binary_dumps(d)

# alternative format - VBKV

d = vdf.binary_loads(vdf_bytes, alt_format=True)
b = vdf.binary_dumps(d, alt_format=True)

# VBKV with header and CRC checking

d = vdf.vbkv_loads(vbkv_bytes)
b = vdf.vbkv_dumps(d)

Using an alternative mapper

.. code:: python

d = vdf.loads(vdf_string, mapper=collections.OrderedDict) d = vdf.loads(vdf_string, mapper=vdf.VDFDict)

VDFDict works much like the regular dict, except it handles duplicates and remembers insert order. Additionally, keys can only be of type str. The most important difference is that when trying to assigning a key that already exist it will create a duplicate instead of reassign the value to the existing key.

.. code:: python

d = vdf.VDFDict() d['key'] = 111 d['key'] = 222 d VDFDict([('key', 111), ('key', 222)]) d.items() [('key', 111), ('key', 222)] d['key'] 111 d[(0, 'key')] # get the first duplicate 111 d[(1, 'key')] # get the second duplicate 222 d.get_all_for('key') [111, 222]

d[(1, 'key')] = 123 # reassign specific duplicate d.get_all_for('key') [111, 123]

d['key'] = 333 d.get_all_for('key') [111, 123, 333] del d[(1, 'key')] d.get_all_for('key') [111, 333] d[(1, 'key')] 333

print vdf.dumps(d) "key" "111" "key" "333"

d.has_duplicates() True d.remove_all_for('key') len(d) 0 d.has_duplicates() False
