Build hook pluginsビルドフックプラグイン


A build hook provides code that will be executed at various stages of the build process. See the documentation for build hook configuration.ビルドフックは、ビルドプロセスのさまざまな段階で実行されるコードを提供します。ビルドフックの設定に関するドキュメントを参照してください。

Overview概要

Build hooks run for every selected version of build targets.ビルドフックは、選択された各バージョンのビルドターゲットに対して実行されます。

The initialization stage occurs immediately before each build and the finalization stage occurs immediately after. Each stage has the opportunity to view or modify build data.初期化ステージは各ビルドの直前に発生し、最終化ステージは直後に発生します。各ステージはビルドデータを表示または変更する機会があります。

Build dataビルドデータ

Build data is a simple mapping whose contents can influence the behavior of builds. Which fields exist and are recognized depends on each build target.ビルドデータは、ビルドの動作に影響を与える可能性のあるシンプルなマッピングです。どのフィールドが存在し認識されるかは、各ビルドターゲットによって異なります。

The following fields are always present and recognized by the build system itself:以下のフィールドは常に存在し、ビルドシステム自体によって認識されます:

Fieldフィールド Type Description説明
artifactsartifacts list[str]list[str] This is a list of extra artifact patterns and should generally only be appended toこれは追加のartifactパターンのリストであり、一般的には追加されるべきです。
force_includeforce_include dict[str, str]dict[str, str] This is a mapping of extra forced inclusion paths, with this mapping taking precedence in case of conflictsこれは追加の強制的なインクルージョンパスのマッピングであり、競合が発生した場合はこのマッピングが優先されます。
build_hooksbuild_hooks tuple[str, ...]tuple[str, ...] This is an immutable sequence of the names of the configured build hooks and matches the order in which they runこれは設定されたビルドフックの名前の不変のシーケンスであり、実行される順序に一致します。

Attention注意

While user-facing TOML options are hyphenated, build data fields should be named with underscores to allow plugins to use them as valid Python identifiers.ユーザー向けのTOMLオプションはハイフンで区切られていますが、ビルドデータフィールドはアンダースコアで命名する必要があります。これにより、プラグインが有効なPython識別子として使用できるようになります。

Notesノート

In some cases it may be necessary to use force_include rather than artifacts. For example, say that you want to install a lib.so directly at the root of site-packages and a project defines a package src/foo. If you create src/lib.so, there will never be a match because the directory traversal starts at src/foo rather than src. In that case you must do either:場合によっては、artifactsの代わりにforce_includeを使用する必要があるかもしれません。たとえば、lib.soを直接site-packagesのルートにインストールしたいとします。そして、プロジェクトがパッケージ src/fooを定義しています。src/lib.soを作成すると、ディレクトリトラバーサルがsrcではなくsrc/fooから始まるため、一致することは決してありません。その場合、次のいずれかを行う必要があります:

build_data['force_include']['src/lib.so'] = 'src/lib.so'

or

build_data['force_include']['/absolute/path/to/src/lib.so'] = 'src/lib.so'

Warning警告

  • For this to have any effect the hook dependency itself cannot be dynamic and must always be defined in build-system.requires.これが効果を持つためには、フックの依存関係自体が動的であってはならず、常にbuild-system.requiresで定義されている必要があります。
  • As the hook must be imported to call this method, imports that require these dependencies must be evaluated lazily.フックをインポートしてこのメソッドを呼び出す必要があるため、これらの依存関係を必要とするインポートは遅延評価されなければなりません。
