Setting external file attributes

[Chaoses-Ib]

Is your feature request related to a problem? Please describe.
Currently, there is only a getter for external file attributes, i.e. ZipFile::unix_mode(), but no way to set external file attributes.

Describe the solution you'd like
Add a setter or option for setting external file attributes.

Progress Updates

• I'll start by exploring the repository structure to understand the codebase and locate the relevant files for ZIP file handling, particularly focusing on the external file attributes functionality.
• Now I'll examine the main library file to understand the structure and then look for the ZipFile implementation and the unix_mode() method mentioned in the request.
• I can see this is a ZIP library. Now I need to find the ZipFile struct and the unix_mode() method. Let me search for "unix_mode" to locate the relevant code.
• Great! I found the unix_mode() method in several files. Let me examine the main implementation in src/read.rs and src/types.rs to understand how external file attributes are currently handled.
• Now let me check the types.rs file to see how unix_mode is implemented at the metadata level, as that's where the actual logic seems to be.
• Let me see more of this function to understand the complete implementation and also look at the ZipFileData struct definition to understand the external_attributes field.
• Now let me find the ZipFileData struct definition to understand the structure and see what fields are available, particularly the external_attributes field.
• Let me continue viewing the struct to find the external_attributes field.
• Perfect! I found the external_attributes field at line 536. Now I need to understand how ZIP files are written to see where I can add a setter for external file attributes. Let me examine the write.rs file to understand the writing process.
• Now let me examine the write.rs file to understand how files are written and where I can add the ability to set external file attributes.
• Let me search for FileOptions in the write.rs file, as that's likely where file options including permissions would be configured.
• Great! I can see there's a permissions field in the FileOptions struct at line 269. Now let me look for methods that set permissions to understand the current API and see where I need to add the external file attributes setter.
• Perfect! I found the unix_permissions method at line 476. Now I need to understand how this is used when creating ZipFileData. Let me look for where the permissions are converted to external_attributes.
• Now let me look for where the permissions are actually converted to external_attributes when writing the file. Let me search for where ZipFileData is created in the write process.
• Excellent! I found the key line at 742: external_attributes: permissions << 16. This shows that the permissions are shifted left by 16 bits to create the external_attributes field. Now let me look at the function signature to understand the complete context.
• Let me find the function signature to understand the complete context of this function.
• Now I have a good understanding of the current implementation. The system currently only supports setting Unix permissions via the unix_permissions method, which are then converted to external_attributes by shifting left 16 bits. I need to add a more general method to set external_attributes directly. Let me create a plan for implementing this feature.
• Analyzing the current implementation and planning the solution for setting external file attributes
• I need to implement a setter for external file attributes in a ZIP library. Currently there's only a getter (unix_mode()) but no way to set external file attributes directly. I need to add this functionality while maintaining backward compatibility.
• Now I'll start implementing the solution by first examining the current FileOptions struct more closely and then adding the external_attributes field and method.
• Now I'll add the external_attributes field to the FileOptions struct. I'll place it near the permissions field since they're related.
• Let me check the exact formatting of the struct to ensure I match it precisely.
• Let me try a more targeted approach by inserting the new field after the permissions line.
• Let me check if there are any special characters or formatting issues by viewing the raw content around that line.
• Let me try using the insert command with the correct syntax.
• Let me try a different approach by replacing a larger section that includes the permissions line and the next line.

⚠️ I'm having technical difficulties. I couldn't solve the issue. I'm going to try again. This might take some time.
