如何创建扩展

创建扩展只需几个步骤：

  1. Open the directory containing the add-on code or theme file.

  2. Add a blender_manifest.toml file with all the required meta-data (name, maintainer, ...).

  3. Use the Blender command-line tool to build the extension .zip file.

如何发布到 Blender 扩展平台：

The extension will be held for review, and published once the moderation team approves it.

扩展文件

An extension is shared as a .zip archive containing a manifest file and other files. The expected files depend on the extension type.

插件扩展

Add-ons need at least the manifest and an __init__.py file, while more complex add-ons have a few different .py files or wheels together.

  1. my_extension-0.0.1.zip
  2. ├─ __init__.py
  3. ├─ blender_manifest.toml
  4. └─ (...)

主题扩展

A theme extension only needs the manifest and the .xml theme file.

  1. my_extension-0.0.1.zip
  2. ├─ blender_manifest.toml
  3. └─ theme.xml

Note

Extensions can optionally have all its files inside a folder (inside the archive). This is a common behavior when saving a repository as ZIP from version-control platforms.

Manifest

A manifest is a file with all the meta-data required for an extension to be processed. This example is a good starting point to the blender_manifest.toml that should be inside the .zip.

  1. schema_version = "1.0.0"
  3. # Example of manifest file for a Blender extension
  4. # Change the values according to your extension
  5. id = "my_example_extension"
  6. version = "1.0.0"
  7. name = "Test Extension"
  8. tagline = "This is another extension"
  9. maintainer = "Developer name <[email protected]>"
  10. # Supported types: "add-on", "theme"
  11. type = "add-on"
  13. # Optional link to documentation, support, source files, etc
  14. # website = "https://extensions.blender.org/add-ons/my-example-package/"
  16. # Optional list defined by Blender and server, see:
  17. # https://docs.blender.org/manual/en/dev/advanced/extensions/tags.html
  18. tags = ["Animation", "Sequencer"]
  20. blender_version_min = "4.2.0"
  21. # # Optional: Blender version that the extension does not support, earlier versions are supported.
  22. # # This can be omitted and defined later on the extensions platform if an issue is found.
  23. # blender_version_max = "5.1.0"

  50. # # * clipboard (to read and/or write the system clipboard)
  51. # # * camera (to capture photos and videos)

  55. # # https://docs.blender.org/manual/en/dev/advanced/extensions/addons.html#internet-access
  56. # #
  57. # # For each permission it is important to also specify the reason why it is required.

List of relative file-paths Python Wheels.

permissions:

Add-ons can list which resources they require. The available options are files, network, clipboard, camera, microphone. Each permission should be followed by an explanation (short single-sentence with no end punctuation (.)).

Optional values for “build”:

These values are only used by the build sub-command.

paths:

A list of file-paths relative to the manifest to include when building the package.

paths_exclude_pattern:

A list of file-path patterns to exclude include when building the package.

The pattern matching is compatible with gitignore.

Note that setting this value isn’t supported when paths is also declared.

If the [build] table isn’t declared the following default is used:

  1. [build]
  2. paths_exclude_pattern = [

If you don’t want to set one of the optional values just exclude it from the manifest altogether.

命令行

Extensions can be built, validated & installed via command-line.

To build the package defined in the current directory use the following commands:

  1. blender --command extension build

详见 构建 文档。

-—

To validate the manifest without building the package:

  1. blender --command extension validate

You may also validate a package without having to extract it first.

  1. blender --command extension validate add-on-package.zip

详见 验证 文档。
