配置

¥Configuration

当 mermaid 启动时，会提取配置以确定要用于图表的配置。有 3 个配置源：

¥When mermaid starts, configuration is extracted to determine a configuration to be used for a diagram. There are 3 sources for configuration:

• 默认配置

  ¥The default configuration

• 站点级别的覆盖由初始化调用设置，并将应用于站点/应用中的所有图表。这个术语是 siteConfig。

  ¥Overrides at the site level are set by the initialize call, and will be applied to all diagrams in the site/app. The term for this is the siteConfig.

• Frontmatter (v10.5.0+) - 图表作者可以更新图表 frontmatter 中选定的配置参数。这些应用于渲染配置。

  ¥Frontmatter (v10.5.0+) - diagram authors can update selected configuration parameters in the frontmatter of the diagram. These are applied to the render config.

• 指令（已被 Frontmatter 弃用） - 图表作者可以通过指令直接在图表代码中更新选定的配置参数。这些应用于渲染配置。

  ¥Directives (Deprecated by Frontmatter) - diagram authors can update selected configuration parameters directly in the diagram code via directives. These are applied to the render config.

渲染配置是在应用这些配置进行渲染时使用的配置。

¥The render config is configuration that is used when rendering by applying these configurations.

前端配置

¥Frontmatter config

整个 mermaid 配置（安全配置除外）可以由图表作者在图表的 frontmatter 中覆盖。Frontmatter 是图顶部的 YAML 块。

¥The entire mermaid configuration (except the secure configs) can be overridden by the diagram author in the frontmatter of the diagram. The frontmatter is a YAML block at the top of the diagram.

主题配置

¥Theme configuration

开始 Mermaid

¥Starting mermaid

初始化

¥Initialize

初始化调用仅应用一次。它由站点集成商调用，以便覆盖站点级别的默认配置。

¥The initialize call is applied only once. It is called by the site integrator in order to override the default configuration at a site level.

configApi.reset

此方法将图表的配置重置为整体站点配置，这是站点集成商提供的配置。每次绘制图表之前，都会从一开始就调用 reset。

¥This method resets the configuration for a diagram to the overall site configuration, which is the configuration provided by the site integrator. Before each rendering of a diagram, reset is called at the very beginning.
