After Pilgrim disappeared from the web in 2011, maintenance continued under later Python maintainers. ### 採用の歴史 chardet became a standard dependency in Python text-processing stacks because it solved the practical problem of guessing encodings for unknown byte streams. The supplied package facts show Homebrew packaging plus Debian and Ubuntu documentation packages, while the README documents normal installation with `pip install chardet`. ### 使われ方 Users call `chardet.detect`, `detect_all`, or `UniversalDetector` from Python, or run `chardetect` on files or stdin to print a guessed encoding and confidence. ### パッケージ好きにとっての重要性 chardet is package-nerd significant because it sits at the messy boundary between package metadata, HTTP downloads, archives, and text decoding. It is also notable for a 2026 chardet 7 rewrite that kept the package name and public API while changing implementation and license. ### タイムライン - 2006: Mark Pilgrim created chardet as a Python port of Mozilla's universal charset detector. - 2008: chardet 1.0.1 released on PyPI according to the official README history. - 2011: Project maintenance continued after Pilgrim deleted his online accounts. - 2012: chardet/chardet public GitHub repository created. - 2017: chardet 3.0.x releases published on GitHub. - 2026: chardet 7.0 released as a ground-up 0BSD-licensed rewrite under the same package name. ### Related projects - Mozilla's universal charset detection library is the upstream idea chardet originally ported. - charset-normalizer is a related Python encoding detector compared directly in the chardet 7 README. ### ソース - - - - ## セキュリティノート narrow executable package without higher-risk signals. - **Geiger リスク:** グリーン / 低 - narrow executable package without higher-risk signals ## ソースデータベース詳細 - **Source Database:** Homebrew formula API - **Tap:** homebrew/core - **Full Name:** chardet - **Version Scheme:** 0 - **Revision:** 0 - **Bottle Stable Root URL:** - **Deprecated:** no - **Disabled:** no - **Keg Only:** no - **URL Keys:** stable ## 他のパッケージマネージャ記録 - Debian apt - python-chardet-doc - 5.2.0+dfsg-2: normalized package name match | Debian stable package indexes: python-chardet-doc from https://deb.debian.org/debian/dists/stable/main/binary-amd64/Packages.xz | Universal Character Encoding Detector (Documentation) | https://github.com/chardet/chardet - Debian apt - python3-chardet - 5.2.0+dfsg-2: normalized package name match | Debian stable package indexes: python3-chardet from https://deb.debian.org/debian/dists/stable/main/binary-amd64/Packages.xz | Universal Character Encoding Detector (Python3) | https://github.com/chardet/chardet - Ubuntu apt - python-chardet-doc - 5.2.0+dfsg-1: normalized package name match | Ubuntu 24.04 LTS package indexes: python-chardet-doc from https://archive.ubuntu.com/ubuntu/dists/noble/main/binary-amd64/Packages.gz | Universal Character Encoding Detector (Documentation) | https://github.com/chardet/chardet - Ubuntu apt - python3-chardet - 5.2.0+dfsg-1: normalized package name match | Ubuntu 24.04 LTS package indexes: python3-chardet from https://archive.ubuntu.com/ubuntu/dists/noble/main/binary-amd64/Packages.gz | Universal Character Encoding Detector (Python3) | https://github.com/chardet/chardet ## 関連リンク - [Terminal utility packages](https://www.automicvault.com/ja/pkg/terminal-utilities/) - Matched terminal and command-line workflow metadata. - [Text processing packages](https://www.automicvault.com/ja/pkg/text-processing-tools/) - Matched text, document, or structured-data processing metadata. - [Developer build packages](https://www.automicvault.com/ja/pkg/developer-build-tools/) - Matched build, compiler, generator, or developer workflow metadata. - [Language runtime packages](https://www.automicvault.com/ja/pkg/language-runtime-packages/) - Matched language runtime, compiler, or interpreter metadata. - [python@3.14](https://www.automicvault.com/ja/pkg/brew/python-3-14/) - Runtime dependency declared by Homebrew. - [abi3audit](https://www.automicvault.com/ja/pkg/brew/abi3audit/) - Shares av.db curated category or tags: cli, developer-tools, python. - [fades](https://www.automicvault.com/ja/pkg/brew/fades/) - Shares av.db curated category or tags: cli, developer-tools, python. - [flake8](https://www.automicvault.com/ja/pkg/brew/flake8/) - Shares av.db curated category or tags: cli, developer-tools, python. - [flit](https://www.automicvault.com/ja/pkg/brew/flit/) - Shares av.db curated category or tags: cli, developer-tools, python. - [hatch](https://www.automicvault.com/ja/pkg/brew/hatch/) - Shares av.db curated category or tags: cli, developer-tools, python. - [isort](https://www.automicvault.com/ja/pkg/brew/isort/) - Shares av.db curated category or tags: cli, developer-tools, python. - [johnnydep](https://www.automicvault.com/ja/pkg/brew/johnnydep/) - Shares av.db curated category or tags: cli, developer-tools, python. - [pdm](https://www.automicvault.com/ja/pkg/brew/pdm/) - Shares av.db curated category or tags: cli, developer-tools, python. - [libchardet](https://www.automicvault.com/ja/pkg/brew/libchardet/) - Local package facts share a topical domain.
