Fix the zh_CN tranlation

Chrome Extension Locale Key Naming Issue Report

Issue Summary

The YouTube extension failed to pack due to invalid locale key names in the Chinese (Simplified) locale file (_locales/zh_CN/messages.json). Chrome extensions have strict naming conventions for locale keys that only allow ASCII letters (a-z, A-Z), numbers (0-9), and underscores (_).

Problem Details

Root Cause

Several locale keys in the Chinese locale file contained invalid characters, including:

• Spaces
• Apostrophes (')
• Exclamation marks (!)
• Parentheses ()
• Special Unicode characters (⫶)
• Hyphens (-)

Affected Keys

The following invalid keys were identified and corrected:

Invalid Key Name	Corrected Key Name	Status
"Disable video playback on hover"	"disableThumbnailPlayback"	✅ Fixed
"Dim Youtube's Pages, except what I mouse-over!"	"cursorLighting"	✅ Fixed
"Hide AI Summaries"	"hideAiSummaries"	✅ Fixed
"Hide Banner Ads (YouTube might deny)"	"hideBannerAds"	✅ Fixed
"Hide Pause Overlay"	"hidePauseOverlay"	✅ Fixed
"Hide YouTube Logo"	"hideYouTubeLogo"	✅ Fixed
"Hide '⫶' (more actions) on thumbnails"	"hideMoreActionsOnThumbnails"	✅ Fixed
"Hide watched videos"	"hideWatchedVideos"	✅ Fixed
"Remove member only videos"	"RemoveMemberOnlyVideos"	✅ Fixed
"Thumbnail Size"	"ThumbnailSize"	✅ Fixed
"Youtube-Search"	"YoutubeSearch"	✅ Fixed

Technical Requirements

Chrome Extension Locale Key Naming Rules

According to Chrome Extension documentation, locale message keys must:

1. Only contains ASCII characters
2. Use letters (a-z, A-Z)
3. Use numbers (0-9)
4. Use underscores (_)
5. NOT contain: spaces, special characters, punctuation, or Unicode characters

Error Messages Encountered

Invalid locale file 'D:\...\zh_CN\messages.json': Name of a key "disable video playback on hover" is invalid. Only ASCII [a-z], [A-Z], [0-9], and "_" are allowed.

Resolution Process

Step 1: Identification

• Used grep search to identify all keys containing invalid characters
• Found 11 problematic keys in the Chinese locale file

Step 2: Cross-Reference

• Checked the English locale file (_locales/en/messages.json) to find correct key names
• Ensured consistency across locale files

Step 3: Correction

• Replaced all invalid keys with proper camelCase or underscore-separated names
• Maintained the original Chinese translations (message values)
• Preserved the JSON structure and formatting

Step 4: Validation

• Verified no remaining invalid characters in key names
• Confirmed all corrections follow Chrome extension naming conventions

Prevention Measures

For Future Development

1. Validation Script: Consider implementing a pre-build validation script to check locale key names
2. Naming Convention Documentation: Create a style guide for locale key naming
3. Code Review Checklist: Add locale key validation to the code review process
4. Automated Testing: Include locale file validation in the CI/CD pipeline

Recommended Naming Patterns

• Use camelCase: hideYouTubeLogo, disableThumbnailPlayback
• Use underscores for compound words: youtube_search, thumbnail_size
• Avoid spaces and special characters entirely
• Be consistent with existing key naming patterns

Files Modified

• _locales/zh_CN/messages.json - All invalid keys corrected

Testing

• Extension now packages successfully without locale key errors
• All functionality preserved with corrected key names
• Chinese translations remain intact

Impact

• Before: Extension packaging failed with locale validation errors
• After: Extension packages are successfully installed and maintain all functionality
• Risk: Low - Only key names changed, not functionality or translations

Yes, I used AI for this MD, but when I was working with this repo and trying to unpack it locally, I came across a translation problem that conflicted with the JSON formatting for Chrome, so I tried to fix it. I hope it helps
