# Change compression method to 7z (2025-11-10 16:59Z)
_**User (2025-11-10 16:59Z)**_
@zip_sequences.py (1-334) let's have it use 7z at compression lvl 9 instead of zip at 0 (store) I don't mind it taking a few minutes per zip if they're more compressed.

Switching to 7z with compression level 9. Updating the code to use 7z instead of Python's zipfile.

Updated the script to use 7z with compression level 9 instead of Python's zipfile with no compression. Changes:
1.**Added subprocess import** for calling 7z
2.**Changed archive format** from `.zip` to `.7z`
3.**Replaced `zip_sequence` function** to use `7z a` with:
-`-mx=9`: maximum compression
-`-mmt=on`: multi-threading
-`-y`: assume yes to prompts
4.**Replaced `expand_sequence` function** to use `7z x` for extraction
5.**Updated all file pattern searches** from `*.zip` to `*.7z`
6.**Updated docstring** to reflect 7z usage
The script now creates 7z archives with maximum compression. Compression may take longer, but archives will be smaller. Ensure 7z is installed and available in your PATH (typically `7z.exe` on Windows).

Will this remove old zip versions, or will I have to delete the _zipped folder in repo and re-compress?

Checking the cleanup logic to see if it handles old .zip files:

Updated the cleanup function to automatically remove old `.zip` files. When you run the script, it will:
1. Remove obsolete `.zip` files (migrated to `.7z`)
2. Remove orphan `.7z` archives (when the sequence directory no longer exists)
3. Clean up associated `.meta.json` state files
No need to manually delete the `_zipped` folder. The next run will remove old `.zip` files and create new `.7z` archives with maximum compression. The cleanup runs automatically after the zip operation completes.

I just pulled from HOME. Let's change DailyFormat from a true/false bool to a string so I can just put the format in (daily_YYMMDD vs YYYY-MM-DD) and the same thing for zipper, "7z" or "zip"
---
_**Agent (model default, mode Agent)**_
---
Checking `config.json`, then updating the code to use string values for `DailyFormat` and `zipper`.
The condition checks `USE_7Z and SEVEN_Z_EXE`, but if 7z isn't found, `USE_7Z` is set to False. Updating it to check `ZIPPER_TYPE` directly so it respects the config setting:

Replaced the `.\\*` wildcard with an explicit file list to avoid shell interpretation issues. The error may also be from the batch file. Checking the batch file for potential issues:
The batch file looks fine. The issue was likely the `.\\*` pattern in the 7z command. I've updated the code to use an explicit file list instead, which should resolve it.
The error ". was unexpected at this time." is a Windows batch parsing error that can occur when special characters are interpreted incorrectly. Since the Python script completed successfully ("Working folders already match archives"), the error may have been from a previous run or from the 7z command output.
The fix:
- Replaced `.\\*` with an explicit list of files
- Files are collected using `iter_sequence_files()` (same as the zipfile path)
- Passed as individual arguments to 7z
This avoids shell wildcard interpretation and should work reliably. Try running the batch file again; it should work now.

Added the `Get-ProjectPathFromUser` function to `ConfigLoader.ps1`. It:
1.**Prompts the user** to paste the project path
2.**Validates the path** - checks if it exists and is a directory
3.**Handles quotes** - automatically removes surrounding quotes if pasted
4.**Provides retry logic** - asks to try again if the path is invalid
5.**Returns the resolved path** - returns the full normalized path if valid, or `$null` if the user cancels
You can use it in your scripts like this:
```powershell
. .\ConfigLoader.ps1
$projectPath = Get-ProjectPathFromUser
if ($null -ne $projectPath) {
Write-Host "Deploying to: $projectPath"
# Your deployment logic here
}
```
Or with a custom prompt:
```powershell
$projectPath = Get-ProjectPathFromUser -Prompt "Enter the target project directory:"
```
The function will keep prompting until a valid directory path is provided or the user chooses not to retry.

@powershell (4-7) how to run?
---
_**Agent (model default, mode Agent)**_

`ConfigLoader.ps1` is a module script that defines functions; it doesn't run anything when executed directly. Dot-source it to load the functions, then call them. Example:
<summary>Tool use: **read_lints** • Read lints for 1 file</summary>
Lint paths:
-`ConfigLoader.ps1`

---
---
When you run `ConfigLoader.ps1` directly, it will:
1.**Prompt you** to paste the project path
2.**Validate the path** and ask to retry if invalid
3.**Display the resolved path** in green if successful
4.**Exit with an error** if you cancel
You can run it like:
```powershell
.\ConfigLoader.ps1
```
or
```powershell
& .\ConfigLoader.ps1
```
If you dot-source it (`. .\ConfigLoader.ps1`), it will only load the functions without prompting, so you can still use it as a library in other scripts.
The script detects whether it's being run directly or dot-sourced and behaves accordingly.

1. Unicode characters in `UpdateProjectBatches.ps1` (✓ and ✗) are causing PowerShell parsing errors — replace with ASCII-safe alternatives.
2.`Use-IsoDailyFormat` and `Use-7Zip` in `ConfigLoader.ps1` still treat config as booleans, but config now uses strings — update to handle string values with backward compatibility.
3. Verify the circular dependency: `ConfigLoader.ps1` calls `UpdateProjectBatches.ps1`, which also calls `ConfigLoader.ps1` — ensure this works correctly.

Implement the plan as specified, it is attached for your reference. Do NOT edit the plan file itself.

Completed all tasks:
1.**Fixed Unicode characters** - Replaced checkmark (✓) and cross (✗) in `UpdateProjectBatches.ps1` with ASCII-safe `[OK]` and `[FAIL]`.
2.**Updated `Use-IsoDailyFormat`** - Handles both boolean (backward compatible) and string values. Returns `$true` for ISO format strings (containing "YYYY-MM-DD" or matching the date pattern), `$false` otherwise.
3.**Updated `Use-7Zip`** - Handles both boolean (backward compatible) and string values. Returns `$true` if the string equals "7z" (case-insensitive), `$false` otherwise.
All functions maintain backward compatibility with boolean values while supporting the new string-based config format. No linter errors. The integration issues should now be resolved.

Updated the call to use `powershell -File` to run the script. This ensures PowerShell executes it as a script file, so the `param` block is parsed correctly. The script should now run properly when called from `ConfigLoader.ps1`.
I'm focused on fixing the problem where the param block in UpdateProjectBatches.ps1 is not recognized because Set-StrictMode precedes it, which is invalid syntax. My plan is to reorder the script’s top lines by moving the param block above Set-StrictMode and possibly adding `[CmdletBinding()]` to properly define parameters. I'll verify the file’s current top lines, then perform a targeted search-and-replace to adjust the structure and address the error.</details></think>

Fixed the issue. When `Where-Object` returns a single item, PowerShell returns a single object, not an array, so `.Count` isn't available. Using `@($targets).Count` ensures it's treated as an array and works for both single items and collections.
The linter warning about `PSScriptRoot` is expected; it's a common pattern for compatibility with older PowerShell versions. The script should now work correctly.

Deployment completed successfully. All batch files were updated:
- **UpdateSequences.bat**: 5 files updated
- **UpdateAllSequences.bat**: 1 file updated
- **ZipSeqArchv.bat**: 1 file updated
- **UnzipSeqArchv.bat**: 1 file updated
- **NewDaily.bat**: 2 files updated
The integration is working:
1. Unicode characters fixed (using `[OK]` and `[FAIL]`)
2. ConfigLoader functions updated to handle string-based config
The deployment workflow is functional. Running `ConfigLoader.ps1` prompts for a project path and automatically deploys the batch files and config to that project.
