As a result, looking up an item by its index was an O(N) operation, while +deletion was O(1). + +This version makes different trade-offs for the sake of efficient lookups. Its +content is a standard Python list instead of a doubly-linked list. This +provides O(1) lookups by index at the expense of O(N) deletion, as well as +slightly faster iteration. + +In Python 3.6 and later, the built-in `dict` type is inherently ordered. If you +ignore the dictionary values, that also gives you a simple ordered set, with +fast O(1) insertion, deletion, iteration and membership testing. However, `dict` +does not provide the list-like random access features of OrderedSet. You +would have to convert it to a list in O(N) to look up the index of an entry or +look up an entry by its index. + + +## Compatibility + +OrderedSet is automatically tested on Python 2.7, 3.4, 3.5, 3.6, and 3.7. +We've checked more informally that it works on PyPy and PyPy3. + + diff --git a/setuptools/_vendor/ordered_set-3.1.1.dist-info/MIT-LICENSE b/setuptools/_vendor/ordered_set-3.1.1.dist-info/MIT-LICENSE new file mode 100644 index 00000000..25117ef4 --- /dev/null +++ b/setuptools/_vendor/ordered_set-3.1.1.dist-info/MIT-LICENSE @@ -0,0 +1,19 @@ +Copyright (c) 2018 Luminoso Technologies, Inc. + +Permission is hereby granted, free of charge, to any person obtaining a +copy of this software and associated documentation files (the "Software"), +to deal in the Software without restriction, including without limitation +the rights to use, copy, modify, merge, publish, distribute, sublicense, +and/or sell copies of the Software, and to permit persons to whom the +Software is furnished to do so, subject to the following conditions: + +The above copyright notice and this permission notice shall be included in +all copies or substantial portions of the Software. + +THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR +IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, +FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.

name="usage"></a> + +### Parse a TOML string<a name="parse-a-toml-string"></a> + +```python +import tomli + +toml_str = """ + gretzky = 99 + + [kurri] + jari = 17 + """ + +toml_dict = tomli.loads(toml_str) +assert toml_dict == {"gretzky": 99, "kurri": {"jari": 17}} +``` + +### Parse a TOML file<a name="parse-a-toml-file"></a> + +```python +import tomli + +with open("path_to_file/conf.toml", "rb") as f: + toml_dict = tomli.load(f) +``` + +The file must be opened in binary mode (with the `"rb"` flag). +Binary mode will enforce decoding the file as UTF-8 with universal newlines disabled, +both of which are required to correctly parse TOML. + +### Handle invalid TOML<a name="handle-invalid-toml"></a> + +```python +import tomli + +try: + toml_dict = tomli.loads("]] this is invalid TOML [[") +except tomli.TOMLDecodeError: + print("Yep, definitely not valid.") +``` + +Note that error messages are considered informational only. +They should not be assumed to stay constant across Tomli versions. + +### Construct `decimal.Decimal`s from TOML floats<a name="construct-decimaldecimals-from-toml-floats"></a> + +```python +from decimal import Decimal +import tomli + +toml_dict = tomli.loads("precision-matters = 0.982492", parse_float=Decimal) +assert toml_dict["precision-matters"] == Decimal("0.982492") +``` + +Note that `decimal.Decimal` can be replaced with another callable that converts a TOML float from string to a Python type. +The `decimal.Decimal` is, however, a practical choice for use cases where float inaccuracies can not be tolerated. + +Illegal types are `dict` and `list`, and their subtypes. +A `ValueError` will be raised if `parse_float` produces illegal types. + +## FAQ<a name="faq"></a> + +### Why this parser?<a

set](https://github.com/toml-lang/compliance/pull/8) + soon to be merged to the official + [compliance tests for TOML](https://github.com/toml-lang/compliance) + repository +- thoroughly tested: 100% branch coverage + +### Is comment preserving round-trip parsing supported?<a name="is-comment-preserving-round-trip-parsing-supported"></a> + +No. + +The `tomli.loads` function returns a plain `dict` that is populated with builtin types and types from the standard library only. +Preserving comments requires a custom type to be returned so will not be supported, +at least not by the `tomli.loads` and `tomli.load` functions. + +Look into [TOML Kit](https://github.com/sdispater/tomlkit) if preservation of style is what you need. + +### Is there a `dumps`, `write` or `encode` function?<a name="is-there-a-dumps-write-or-encode-function"></a> + +[Tomli-W](https://github.com/hukkin/tomli-w) is the write-only counterpart of Tomli, providing `dump` and `dumps` functions. + +The core library does not include write capability, as most TOML use cases are read-only, and Tomli intends to be minimal. + +### How do TOML types map into Python types?<a name="how-do-toml-types-map-into-python-types"></a> + +| TOML type | Python type | Details | +| ---------------- | ------------------- | ------------------------------------------------------------ | +| Document Root | `dict` | | +| Key | `str` | | +| String | `str` | | +| Integer | `int` | | +| Float | `float` | | +| Boolean | `bool` | | +| Offset Date-Time | `datetime.datetime` | `tzinfo`

HISTORY OF THE SOFTWARE +========================== + +Python was created in the early 1990s by Guido van Rossum at Stichting +Mathematisch Centrum (CWI, see http://www.cwi.nl) in the Netherlands +as a successor of a language called ABC. Guido remains Python's +principal author, although it includes many contributions from others. + +In 1995, Guido continued his work on Python at the Corporation for +National Research Initiatives (CNRI, see http://www.cnri.reston.va.us) +in Reston, Virginia where he released several versions of the +software. + +In May 2000, Guido and the Python core development team moved to +BeOpen.com to form the BeOpen PythonLabs team. In October of the same +year, the PythonLabs team moved to Digital Creations (now Zope +Corporation, see http://www.zope.com). In 2001, the Python Software +Foundation (PSF, see http://www.python.org/psf/) was formed, a +non-profit organization created specifically to own Python-related +Intellectual Property. Zope Corporation is a sponsoring member of +the PSF. + +All Python releases are Open Source (see http://www.opensource.org for +the Open Source Definition). Historically, most, but not all, Python +releases have also been GPL-compatible; the table below summarizes +the various releases. + + Release Derived Year Owner GPL- + from compatible?

All Python licenses, unlike the GPL, let you distribute + a modified version without making your changes open source. The + GPL-compatible licenses make it possible to combine Python with + other software that is released under the GPL; the others don't. + +(2) According to Richard Stallman, 1.6.1 is not GPL-compatible, + because its license has a choice of law clause. According to + CNRI, however, Stallman's lawyer has told CNRI's lawyer that 1.6.1 + is "not incompatible" with the GPL. + +Thanks to the many outside volunteers who have worked under Guido's +direction to make these releases possible. + + +B.
