Walkthrough

The pull request introduces a Windows CP-1252 encoding workaround in Swift, specifically addressing file parsing and string conversion challenges. The changes span multiple files, focusing on adding a robust mechanism to handle Windows CP-1252 encoded files across different operating systems. The modifications include a new encoding mapping, a custom string conversion method, and updates to the HTML file parsing logic to leverage this new encoding support.

Where Windows encoding takes flight!
CP-1252, no longer a pain,
Our rabbit decoder breaks the chain 🔤
Decoding magic, line by line! 🌟

🪧 Tips

Chat

There are 3 ways to chat with CodeRabbit:

• Review comments: Directly reply to a review comment made by CodeRabbit. Example:
  • I pushed a fix in commit <commit_id>, please review it.
  • Generate unit testing code for this file.
  • Open a follow-up GitHub issue for this discussion.
• Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
  • @coderabbitai generate unit testing code for this file.
  • @coderabbitai modularize this function.
• PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
  • @coderabbitai gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.
  • @coderabbitai read src/utils.ts and generate unit testing code.
  • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.
  • @coderabbitai help me debug CodeRabbit configuration file.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.

🧹 Nitpick comments (3)

src/swift-server/importer/importers/file-parser.swift (1)

15-21: Consider enhancing error handling for encoding failures.

The current implementation throws a generic E10007 exception for all encoding failures. Consider differentiating between Windows CP-1252 and other encoding failures to aid in debugging.

 switch encoding {
 case .windowsCP1252:
   fileString = String.fromWindowsCP1252(fileData)
+  guard let fileString else {
+    throw Exception(.E10007, context: [
+      "fileName": filePath,
+      "encoding": "Windows CP-1252"
+    ])
+  }
 default:
   fileString = String(data: fileData, encoding: encoding)
+  guard let fileString else {
+    throw Exception(.E10007, context: [
+      "fileName": filePath,
+      "encoding": String(describing: encoding)
+    ])
+  }
 }
-guard let fileString
-else {
-  throw Exception(.E10007, context: ["fileName": filePath])
-}

1-4: Enhance header documentation.

Consider adding more context about the issue being worked around and when this workaround can be removed.

-// Workarround to be able to decode windowsCP1252 files
-// thanks to @TimBudarick
-// To be remove when the following issue is fixed: https://github.com/swiftlang/swift/issues/78382
+// Temporary workaround for Windows CP-1252 encoding support in Swift
+// This implementation provides a manual decoder for Windows CP-1252 encoded files
+// as Swift's built-in support is currently incomplete.
+//
+// Credits: @TimBudarick
+// 
+// TODO: Remove this workaround when Swift adds proper Windows CP-1252 support
+// Tracking issue: https://github.com/swiftlang/swift/issues/78382

276-292: Consider performance optimization for large files.

The current implementation builds the string by repeatedly appending characters, which can be inefficient for large files. Consider pre-allocating the string capacity or using a more efficient string building approach.

 static func fromWindowsCP1252(_ data: Data) -> String? {
   #if os(macOS)
     return String(data: data, encoding: .windowsCP1252)
   #else
-    var decodedString = ""
+    // Pre-allocate capacity to avoid repeated reallocations
+    var decodedString = String()
+    decodedString.reserveCapacity(data.count)
 
     for byte in data {
       if let character = String.Encoding.windowsCP1252Map[byte] {
         decodedString.append(character)
       } else {
         return nil
       }
     }
 
     return decodedString
   #endif
 }

8-265: Well-implemented character mapping!

The Windows CP-1252 mapping is comprehensive and well-documented. Good practice using the Unicode replacement character (U+FFFD) for undefined code points.
