Walkthrough

The changes involve modifications to the Toolbar.vue component in the packages/design-core/src/preview/src directory. An additional property :options="langOptions" is added to the ChangeLang component, allowing it to accept language options. The import statement is updated to include getMergeMeta, and a new constant langOptions is defined to retrieve these options. This constant is returned from the setup function, maintaining the overall structure of the component while enhancing its functionality.

11-11: Approve the addition of language options to ChangeLang component

The addition of :options="langOptions" to the ChangeLang component enhances its functionality by providing language options. This change aligns with the PR objective of fixing a preview error and improves the language selection feature.

Consider renaming the prop to :languageOptions for improved clarity:

-<component :is="ChangeLang" :langChannel="previewLangChannel" :options="langOptions"></component>
+<component :is="ChangeLang" :langChannel="previewLangChannel" :languageOptions="langOptions"></component>

---

31-31: Approve the addition of langOptions and suggest error handling

The addition of langOptions using getMergeMeta('engine.toolbars.lang').options is appropriate and consistent with the changes in the template. This approach centralizes the configuration of language options, improving maintainability.

Consider adding error handling to gracefully manage cases where the language options might not be available:

const langOptions = getMergeMeta('engine.toolbars.lang')?.options || []

This ensures that langOptions will always be an array, even if the metadata is unavailable or doesn't contain the expected structure.

17-17: Approve the import of getMergeMeta

The addition of getMergeMeta to the import statement is appropriate and necessary for retrieving the language options metadata. This change is consistent with the existing imports and supports the new functionality added to the component.

11-11: Summary: Effective implementation of language options feature

The changes in this file work together to implement a language options feature for the Toolbar component:

1. The ChangeLang component now receives language options via the :options prop.
2. The getMergeMeta function is imported to retrieve language metadata.
3. The langOptions constant is defined using getMergeMeta and made available to the template.

These modifications effectively address the PR objective of fixing a preview error related to language selection. The implementation maintains good practices such as centralized configuration and component-based architecture.

To ensure the changes are consistent across the codebase, please run the following verification script:

#!/bin/bash
# Description: Verify the usage of getMergeMeta for language options and the ChangeLang component props

# Test 1: Check for other usages of getMergeMeta for language options
echo "Checking for other usages of getMergeMeta for language options:"
rg --type vue --type js "getMergeMeta\(['\"]engine\.toolbars\.lang['\"]" -g '!packages/design-core/src/preview/src/Toolbar.vue'

# Test 2: Check for other instances of the ChangeLang component
echo "Checking for other instances of the ChangeLang component:"
rg --type vue "<component\s+:is=\"ChangeLang\"" -g '!packages/design-core/src/preview/src/Toolbar.vue'

# Test 3: Verify the definition of the ChangeLang component
echo "Verifying the definition of the ChangeLang component:"
rg --type vue --type js "export default.*ChangeLang"

This script will help identify any inconsistencies in how language options are handled across the codebase and ensure that the ChangeLang component is used consistently.
