Product Overview +Product Name: KV-Tube Version: 1.0 (In Development) Description: KV-Tube is a comprehensive media center web application designed to provide an ad-free YouTube experience, a curated movie streaming service, and a local video management system. It emphasizes privacy, absence of advertisements, and utility features like AI summarization and language learning tools. + +2. User Personas +The Binge Watcher: Wants uninterrupted access to YouTube content and movies without ads. +The Archivist: Maintains a local collection of videos and wants a clean interface to organize and watch them securely. +The Learner: Uses video content for educational purposes, specifically English learning. +The Tech Enthusiast: Appreciates PWA support, torrent integration, and customizable settings. +3. Core Features +3.1. YouTube Viewer (Home) +Ad-Free Experience: Plays YouTube videos without third-party advertisements. +Search: Integrated search bar powered by yt-dlp to find videos, channels, and playlists. +Playback: Custom video player with support for quality selection and playback speed. +AI Summarization: Feature to summarize video content using Google Gemini API (Optional). +3.2. local Video Manager ("My Videos") +Secure Access: Password-protected section for personal video collections. +File Management: Scans local directories for video files. +Metadata: Extracts metadata (duration, format) and generates thumbnails using FFmpeg/MoviePy. +Playback: Native HTML5 player for local files. +3.3. Utilities +Torrent Player: Interface for streaming/playing video content via torrents. +Playlist Manager: Create and manage custom playlists of YouTube videos. +Camera/Photo: ("Chụp ảnh") Feature to capture or manage photos (Webcam integration). +Configuration: Web-based settings to manage application behavior (e.g., password, storage paths). +4. Technical Architecture +Backend: Python / Flask +Frontend: HTML5, CSS3, JavaScript (Vanilla) +Database/Storage: JSON-based local storage and file system. +Video Processing: yt-dlp (YouTube), FFmpeg (Conversion/Thumbnail), MoviePy (Optional). +AI Service: Google Gemini API (for summarization). +Deployment: Docker container support (xehopnet/kctube). +5. Non-Functional Requirements +Performance: Fast load times and responsive UI. +Compatibility: PWA-ready for installation on desktop and mobile. +Reliability: graceful degradation if optional dependencies (MoviePy, Gemini) are missing. +Privacy: No user tracking or external analytics. +6. Known Limitations +Search Reliability: Dependent on yt-dlp stability and YouTube's anti-bot measures. +External APIs: Movie features rely on third-party APIs which may have downtime. +Dependency Management: Some Python libraries (MoviePy, Numpy) require compilation tools. +7. Future Roadmap +Database: Migrate from JSON to SQLite for better performance with large libraries. +User Accounts: Individual user profiles and history. +Offline Mode: Enhanced offline capabilities for PWA. +Casting: Support for Chromecast/AirPlay. \ No newline at end of file diff --git a/docker-compose.yml b/docker-compose.yml new file mode 100644 index 0000000..0ffc02b --- /dev/null +++ b/docker-compose.yml @@ -0,0 +1,29 @@ +# KV-Tube Docker Compose for Synology NAS +# Usage: docker-compose up -d + +version: '3.8' + +services: + kv-tube: + build: . + image: vndangkhoa/kv-tube:latest + container_name: kv-tube + restart: unless-stopped + ports: + - "5011:5000" + volumes: + # Persist data (Easy setup: Just maps a folder) + - ./data:/app/data + # Local videos folder (Optional) + # - ./videos:/app/youtube_downloads + environment: + - PYTHONUNBUFFERED=1 + - FLASK_ENV=production + healthcheck: + test: [ "CMD", "curl", "-f", "http://localhost:5000/" ] + interval: 30s + timeout: 10s + retries: 3 + start_period: 10s + labels: + - "com.centurylinklabs.watchtower.enable=true" diff --git a/entrypoint.sh b/entrypoint.sh new file mode 100644 index 0000000..fe94d8f --- /dev/null +++ b/entrypoint.sh @@ -0,0 +1,21 @@ +#!/bin/sh +set -e + +echo "--- KV-Tube Startup ---" + +# 1.

The separate type ''unicode'' holds Unicode text. +Unicode literals are specified via the u'...' prefix. Indexing or slicing +either type always produces a string of the same type as the original. +Data read from a file is always of '''str'' type. + +In Python 3.x, strings (type ''str'') may only contain Unicode text. The u'...' +prefix and the ''unicode'' type are now redundant. A new type (called +''bytes'') has to be used for binary data (including any particular +''encoding'' of a string). The b'...' prefix allows one to specify a binary +literal. Indexing or slicing a string produces another string. Slicing a byte +string produces another byte string, but the indexing operation produces an +integer. Data read from a file is of '''str'' type if the file was opened in +text mode, or of ''bytes'' type otherwise. + +Since PyCryptodome aims at supporting both Python 2.x and 3.x, the following helper +functions are used to keep the rest of the library as independent as possible +from the actual Python version. + +In general, the code should always deal with binary strings, and use integers +instead of 1-byte character strings. + +b(s) + Take a text string literal (with no prefix or with u'...' prefix) and + make a byte string. +bchr(c) + Take an integer and make a 1-character byte string. +bord(c) + Take the result of indexing on a byte string and make an integer. +tobytes(s) + Take a text string, a byte string, or a sequence of character taken from + a byte string and make a byte string. +""" + +import sys +import abc + + +if sys.version_info[0] == 2: + def b(s): + return s + def bchr(s): + return chr(s) + def bstr(s): + return str(s) + def bord(s): + return ord(s) + def tobytes(s, encoding="latin-1"): + if isinstance(s, unicode): + return s.encode(encoding) + elif isinstance(s, str): + return s + elif isinstance(s, bytearray): + return bytes(s) + elif isinstance(s, memoryview): + return s.tobytes() + else: + return ''.join(s) + def tostr(bs): + return bs + def byte_string(s): + return isinstance(s, str) + + #

Brotli

+ +### Introduction + +Brotli is a generic-purpose lossless compression algorithm that compresses data +using a combination of a modern variant of the LZ77 algorithm, Huffman coding +and 2nd order context modeling, with a compression ratio comparable to the best +currently available general-purpose compression methods. It is similar in speed +with deflate but offers more dense compression. + +The specification of the Brotli Compressed Data Format is defined in +[RFC 7932](https://datatracker.ietf.org/doc/html/rfc7932). + +Brotli is open-sourced under the MIT License, see the LICENSE file. + +> **Please note:** brotli is a "stream" format; it does not contain +> meta-information, like checksums or uncompressed data length. It is possible +> to modify "raw" ranges of the compressed stream and the decoder will not +> notice that. + +### Installation + +In most Linux distributions, installing `brotli` is just a matter of using +the package management system. For example in Debian-based distributions: +`apt install brotli` will install `brotli`. On MacOS, you can use +[Homebrew](https://brew.sh/): `brew install brotli`. + +[![brotli packaging status](https://repology.org/badge/vertical-allrepos/brotli.svg?exclude_unsupported=1&columns=3&exclude_sources=modules,site&header=brotli%20packaging%20status)](https://repology.org/project/brotli/versions) + +Of course you can also build brotli from sources. + +### Build instructions + +#### Vcpkg + +You can download and install brotli using the +[vcpkg](https://github.com/Microsoft/vcpkg/) dependency manager: + + git clone https://github.com/Microsoft/vcpkg.git + cd vcpkg + ./bootstrap-vcpkg.sh + ./vcpkg integrate install + ./vcpkg install brotli + +The brotli port in vcpkg is kept up to date by Microsoft team members and +community contributors. If the version is out of date, please [create an issue +or pull request](https://github.com/Microsoft/vcpkg) on the vcpkg repository. + +#### Bazel + +See [Bazel](https://www.bazel.build/) + +#### CMake + +The basic commands to build and install brotli are: + + $ mkdir out && cd out + $ cmake -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=./installed .. + $ cmake --build . --config Release --target install + +You can use other [CMake](https://cmake.org/) configuration. + +#### Python + +To install the latest release of the Python module, run the following: + + $ pip install brotli + +To install the tip-of-the-tree version, run: + + $ pip install --upgrade git+https://github.com/google/brotli + +See the [Python readme](python/README.md) for more details on installing +from source, development, and testing. + +### Contributing + +We glad to answer/library related questions in +[brotli mailing list](https://groups.google.com/g/brotli). + +Regular issues / feature requests should be reported in +[issue tracker](https://github.com/google/brotli/issues). + +For reporting vulnerability please read [SECURITY](SECURITY.md). + +For contributing changes please read [CONTRIBUTING](CONTRIBUTING.md). + +### Benchmarks +* [Squash Compression Benchmark](https://quixdb.github.io/squash-benchmark/) / [Unstable Squash Compression Benchmark](https://quixdb.github.io/squash-benchmark/unstable/) +* [Large Text Compression Benchmark](https://mattmahoney.net/dc/text.html) +* [Lzturbo Benchmark](https://sites.google.com/site/powturbo/home/benchmark) + +### Related projects +> **Disclaimer:** Brotli authors take no responsibility for the third party projects mentioned in this section. + +Independent [decoder](https://github.com/madler/brotli) implementation +by Mark Adler, based entirely on format specification. + +JavaScript port of brotli [decoder](https://github.com/devongovett/brotli.js). +Could be used directly via `npm install brotli` + +Hand ported [decoder / encoder](https://github.com/dominikhlbg/BrotliHaxe) +in haxe by Dominik Homberger. +Output source code: JavaScript, PHP, Python, Java and C# + +7Zip [plugin](https://github.com/mcmilk/7-Zip-Zstd) + +Dart compression framework with +[fast FFI-based Brotli implementation](https://pub.dev/documentation/es_compression/latest/brotli/) +with ready-to-use prebuilt binaries for Win/Linux/Mac diff --git a/venv/lib/python3.14/site-packages/brotli-1.2.0.dist-info/RECORD b/venv/lib/python3.14/site-packages/brotli-1.2.0.dist-info/RECORD new file mode 100644 index 0000000..212a8c4 --- /dev/null +++ b/venv/lib/python3.14/site-packages/brotli-1.2.0.dist-info/RECORD @@ -0,0 +1,9 @@ +__pycache__/brotli.cpython-314.pyc,, +_brotli.cpython-314-darwin.so,sha256=kyHNjfBWu_RTUj2on_cZtAwWafk8D7WOa0xttgVSjPE,1920112 +brotli-1.2.0.dist-info/INSTALLER,sha256=zuuue4knoyJ-UwPPXg8fezS7VCrXJQrAP7zeNuwvFQg,4 +brotli-1.2.0.dist-info/METADATA,sha256=-dEtUYS1CQsUay5fDWKTFSGysUNepGZDOiObt8QfyWI,6116 +brotli-1.2.0.dist-info/RECORD,, +brotli-1.2.0.dist-info/WHEEL,sha256=MzHA8aA11K4m-mjpjTobbWUqTlhv5RdoytLBFWQb_k4,142 +brotli-1.2.0.dist-info/licenses/LICENSE,sha256=PRgACONpIqTo2uwRw0x68mT-1ZYtB5JK6pKMOOhmPJQ,1084 +brotli-1.2.0.dist-info/top_level.txt,sha256=gsS54HrhO3ZveFxeMrKo_7qH4Sm4TbQ7jGLVBEqJ4NI,15 +brotli.py,sha256=gTYQvw10ppmNe0fZEuiJLDiW5urBnLeyJXXgT8KUtj8,1970 diff --git a/venv/lib/python3.14/site-packages/brotli-1.2.0.dist-info/WHEEL b/venv/lib/python3.14/site-packages/brotli-1.2.0.dist-info/WHEEL new file mode 100644 index 0000000..3884d2a --- /dev/null +++ b/venv/lib/python3.14/site-packages/brotli-1.2.0.dist-info/WHEEL @@ -0,0 +1,6 @@ +Wheel-Version: 1.0 +Generator: setuptools (80.9.0) +Root-Is-Purelib: false +Tag: cp314-cp314-macosx_10_15_universal2 +Generator: delocate 0.13.0 + diff --git a/venv/lib/python3.14/site-packages/brotli-1.2.0.dist-info/licenses/LICENSE b/venv/lib/python3.14/site-packages/brotli-1.2.0.dist-info/licenses/LICENSE new file mode 100644 index 0000000..33b7cdd --- /dev/null +++ b/venv/lib/python3.14/site-packages/brotli-1.2.0.dist-info/licenses/LICENSE @@ -0,0 +1,19 @@ +Copyright (c) 2009, 2010, 2013-2016 by the Brotli Authors. + +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.

Also! I never back down on a good challenge! + +I **don't care** about the **originating charset** encoding, because **two different tables** can +produce **two identical rendered string.** +What I want is to get readable text, the best I can. + +In a way, **I'm brute forcing text decoding.** How cool is that ? 😎 + +Don't confuse package **ftfy** with charset-normalizer or chardet. ftfy goal is to repair Unicode string whereas charset-normalizer to convert raw file in unknown encoding to unicode. + +## 🍰 How + + - Discard all charset encoding table that could not fit the binary content. + - Measure noise, or the mess once opened (by chunks) with a corresponding charset encoding. + - Extract matches with the lowest mess detected. + - Additionally, we measure coherence / probe for a language. + +**Wait a minute**, what is noise/mess and coherence according to **YOU ?** + +*Noise :* I opened hundred of text files, **written by humans**, with the wrong encoding table. **I observed**, then +**I established** some ground rules about **what is obvious** when **it seems like** a mess (aka. defining noise in rendered text). + I know that my interpretation of what is noise is probably incomplete, feel free to contribute in order to + improve or rewrite it. + +*Coherence :* For each language there is on earth, we have computed ranked letter appearance occurrences (the best we can). So I thought +that intel is worth something here. So I use those records against decoded text to check if I can detect intelligent design. + +## ⚡ Known limitations + + - Language detection is unreliable when text contains two or more languages sharing identical letters. (eg. HTML (english tags) + Turkish content (Sharing Latin characters)) + - Every charset detector heavily depends on sufficient content. In common cases, do not bother run detection on very tiny content. + +## ⚠️ About Python EOLs + +**If you are running:** + +- Python >=2.7,<3.5: Unsupported +- Python 3.5: charset-normalizer < 2.1 +- Python 3.6: charset-normalizer < 3.1 +- Python 3.7: charset-normalizer < 4.0 + +Upgrade your Python interpreter as soon as possible. + +## 👤 Contributing + +Contributions, issues and feature requests are very much welcome.

+ +# Flask + +Flask is a lightweight [WSGI] web application framework. It is designed +to make getting started quick and easy, with the ability to scale up to +complex applications. It began as a simple wrapper around [Werkzeug] +and [Jinja], and has become one of the most popular Python web +application frameworks. + +Flask offers suggestions, but doesn't enforce any dependencies or +project layout. It is up to the developer to choose the tools and +libraries they want to use. There are many extensions provided by the +community that make adding new functionality easy. + +[WSGI]: https://wsgi.readthedocs.io/ +[Werkzeug]: https://werkzeug.palletsprojects.com/ +[Jinja]: https://jinja.palletsprojects.com/ + +## A Simple Example + +```python +# save this as app.py +from flask import Flask + +app = Flask(__name__) + +@app.route("/") +def hello(): + return "Hello, World!" +``` + +``` +$ flask run + * Running on http://127.0.0.1:5000/ (Press CTRL+C to quit) +``` + +## Donate + +The Pallets organization develops and supports Flask and the libraries +it uses.

The application will work even with `__name__`, thanks + to how resources are looked up. However it will make debugging more + painful. Certain extensions can make assumptions based on the + import name of your application. For example the Flask-SQLAlchemy + extension will look for the code in your application that triggered + an SQL query in debug mode.

This library +is a suitable replacement for the “encodings.idna” +module that comes with the Python standard library, but which +only supports an older superseded IDNA specification from 2003. + +Basic functions are simply executed: + +.. code-block:: pycon + + >>> import idna + >>> idna.encode('ドメイン.テスト') + b'xn--eckwd4c7c.xn--zckzah' + >>> print(idna.decode('xn--eckwd4c7c.xn--zckzah')) + ドメイン.テスト + + +Installation +------------ + +This package is available for installation from PyPI via the +typical mechanisms, such as: + +.. code-block:: bash + + $ python3 -m pip install idna + + +Usage +----- + +For typical usage, the ``encode`` and ``decode`` functions will take a +domain name argument and perform a conversion to ASCII compatible encoding +(known as A-labels), or to Unicode strings (known as U-labels) +respectively. + +.. code-block:: pycon + + >>> import idna + >>> idna.encode('ドメイン.テスト') + b'xn--eckwd4c7c.xn--zckzah' + >>> print(idna.decode('xn--eckwd4c7c.xn--zckzah')) + ドメイン.テスト + +Conversions can be applied at a per-label basis using the ``ulabel`` or +``alabel`` functions if necessary: + +.. code-block:: pycon + + >>> idna.alabel('测试') + b'xn--0zwm56d' + + +Compatibility Mapping (UTS #46) ++++++++++++++++++++++++++++++++ + +This library provides support for `Unicode IDNA Compatibility +Processing `_ which normalizes input from +different potential ways a user may input a domain prior to performing the IDNA +conversion operations. This functionality, known as a +`mapping `_, is considered by the +specification to be a local user-interface issue distinct from IDNA +conversion functionality. + +For example, “Königsgäßchen” is not a permissible label as *LATIN +CAPITAL LETTER K* is not allowed (nor are capital letters in general). +UTS 46 will convert this into lower case prior to applying the IDNA +conversion. + +.. code-block:: pycon + + >>> import idna + >>> idna.encode('Königsgäßchen') + ... + idna.core.InvalidCodepoint: Codepoint U+004B at position 1 of 'Königsgäßchen' not allowed + >>> idna.encode('Königsgäßchen', uts46=True) + b'xn--knigsgchen-b4a3dun' + >>> print(idna.decode('xn--knigsgchen-b4a3dun')) + königsgäßchen + + +Exceptions +---------- + +All errors raised during the conversion following the specification +should raise an exception derived from the ``idna.IDNAError`` base +class. + +More specific exceptions that may be generated as ``idna.IDNABidiError`` +when the error reflects an illegal combination of left-to-right and +right-to-left characters in a label; ``idna.InvalidCodepoint`` when +a specific codepoint is an illegal character in an IDN label (i.e. +INVALID); and ``idna.InvalidCodepointContext`` when the codepoint is +illegal based on its position in the string (i.e. it is CONTEXTO or CONTEXTJ +but the contextual requirements are not satisfied.) + +Building and Diagnostics +------------------------ + +The IDNA and UTS 46 functionality relies upon pre-calculated lookup +tables for performance. These tables are derived from computing against +eligibility criteria in the respective standards using the command-line +script ``tools/idna-data``. + +This tool will fetch relevant codepoint data from the Unicode repository +and perform the required calculations to identify eligibility. There are +three main modes: + +* ``idna-data make-libdata``. Generates ``idnadata.py`` and + ``uts46data.py``, the pre-calculated lookup tables used for IDNA and + UTS 46 conversions. Implementers who wish to track this library against + a different Unicode version may use this tool to manually generate a + different version of the ``idnadata.py`` and ``uts46data.py`` files. + +* ``idna-data make-table``. Generate a table of the IDNA disposition + (e.g. PVALID, CONTEXTJ, CONTEXTO) in the format found in Appendix + B.1 of RFC 5892 and the pre-computed tables published by `IANA + `_. + +* ``idna-data U+0061``. Prints debugging output on the various + properties associated with an individual Unicode codepoint (in this + case, U+0061), that are used to assess the IDNA and UTS 46 status of a + codepoint. This is helpful in debugging or analysis. + +The tool accepts a number of arguments, described using ``idna-data +-h``. Most notably, the ``--version`` argument allows the specification +of the version of Unicode to be used in computing the table data. For +example, ``idna-data --version 9.0.0 make-libdata`` will generate +library data against Unicode 9.0.0. + + +Additional Notes +---------------- + +* **Packages**. The latest tagged release version is published in the + `Python Package Index `_. + +* **Version support**. This library supports Python 3.8 and higher. + As this library serves as a low-level toolkit for a variety of + applications, many of which strive for broad compatibility with older + Python versions, there is no rush to remove older interpreter support. + Support for older versions are likely to be removed from new releases + as automated tests can no longer easily be run, i.e. once the Python + version is officially end-of-life. + +* **Testing**. The library has a test suite based on each rule of the + IDNA specification, as well as tests that are provided as part of the + Unicode Technical Standard 46, `Unicode IDNA Compatibility Processing + `_. + +* **Emoji**. It is an occasional request to support emoji domains in + this library. Encoding of symbols like emoji is expressly prohibited by + the technical standard IDNA 2008 and emoji domains are broadly phased + out across the domain industry due to associated security risks. For + now, applications that need to support these non-compliant labels + may wish to consider trying the encode/decode operation in this library + first, and then falling back to using `encodings.idna`. See `the Github + project `_ for more discussion. + +* **Transitional processing**. Unicode 16.0.0 removed transitional + processing so the `transitional` argument for the encode() method + no longer has any effect and will be removed at a later date. + diff --git a/venv/lib/python3.14/site-packages/idna-3.11.dist-info/RECORD b/venv/lib/python3.14/site-packages/idna-3.11.dist-info/RECORD new file mode 100644 index 0000000..72879e2 --- /dev/null +++ b/venv/lib/python3.14/site-packages/idna-3.11.dist-info/RECORD @@ -0,0 +1,22 @@ +idna-3.11.dist-info/INSTALLER,sha256=zuuue4knoyJ-UwPPXg8fezS7VCrXJQrAP7zeNuwvFQg,4 +idna-3.11.dist-info/METADATA,sha256=fCwSww9SuiN8TIHllFSASUQCW55hAs8dzKnr9RaEEbA,8378 +idna-3.11.dist-info/RECORD,, +idna-3.11.dist-info/WHEEL,sha256=G2gURzTEtmeR8nrdXUJfNiB3VYVxigPQ-bEQujpNiNs,82 +idna-3.11.dist-info/licenses/LICENSE.md,sha256=t6M2q_OwThgOwGXN0W5wXQeeHMehT5EKpukYfza5zYc,1541 +idna/__init__.py,sha256=MPqNDLZbXqGaNdXxAFhiqFPKEQXju2jNQhCey6-5eJM,868 +idna/__pycache__/__init__.cpython-314.pyc,, +idna/__pycache__/codec.cpython-314.pyc,, +idna/__pycache__/compat.cpython-314.pyc,, +idna/__pycache__/core.cpython-314.pyc,, +idna/__pycache__/idnadata.cpython-314.pyc,, +idna/__pycache__/intranges.cpython-314.pyc,, +idna/__pycache__/package_data.cpython-314.pyc,, +idna/__pycache__/uts46data.cpython-314.pyc,, +idna/codec.py,sha256=M2SGWN7cs_6B32QmKTyTN6xQGZeYQgQ2wiX3_DR6loE,3438 +idna/compat.py,sha256=RzLy6QQCdl9784aFhb2EX9EKGCJjg0P3PilGdeXXcx8,316 +idna/core.py,sha256=P26_XVycuMTZ1R2mNK1ZREVzM5mvTzdabBXfyZVU1Lc,13246 +idna/idnadata.py,sha256=SG8jhaGE53iiD6B49pt2pwTv_UvClciWE-N54oR2p4U,79623 +idna/intranges.py,sha256=amUtkdhYcQG8Zr-CoMM_kVRacxkivC1WgxN1b63KKdU,1898 +idna/package_data.py,sha256=_CUavOxobnbyNG2FLyHoN8QHP3QM9W1tKuw7eq9QwBk,21 +idna/py.typed,sha256=47DEQpj8HBSa-_TImW-5JCeuQeRkm5NMpJWZG3hSuFU,0 +idna/uts46data.py,sha256=H9J35VkD0F9L9mKOqjeNGd2A-Va6FlPoz6Jz4K7h-ps,243725 diff --git a/venv/lib/python3.14/site-packages/idna-3.11.dist-info/WHEEL b/venv/lib/python3.14/site-packages/idna-3.11.dist-info/WHEEL new file mode 100644 index 0000000..d8b9936 --- /dev/null +++ b/venv/lib/python3.14/site-packages/idna-3.11.dist-info/WHEEL @@ -0,0 +1,4 @@ +Wheel-Version: 1.0 +Generator: flit 3.12.0 +Root-Is-Purelib: true +Tag: py3-none-any diff --git a/venv/lib/python3.14/site-packages/idna-3.11.dist-info/licenses/LICENSE.md b/venv/lib/python3.14/site-packages/idna-3.11.dist-info/licenses/LICENSE.md new file mode 100644 index 0000000..256ba90 --- /dev/null +++ b/venv/lib/python3.14/site-packages/idna-3.11.dist-info/licenses/LICENSE.md @@ -0,0 +1,31 @@ +BSD 3-Clause License + +Copyright (c) 2013-2025, Kim Davies and contributors. +All rights reserved. + +Redistribution and use in source and binary forms, with or without +modification, are permitted provided that the following conditions are +met: + +1.
