What & why

Before: after extracting an archive, you had to find it in Finder and move it to the Trash yourself.

Now: a new setting, Settings ▸ General ▸ "Move to Trash after extraction" (off by default). When the whole archive has been extracted successfully, MacPacker moves it to the Trash, without asking — the Trash is the way back. This works from the archive window's Extract archive, from Finder's Extract actions, and from Quick Look's Extract archive when it extracts next to the archive.

  • Only after a complete, successful extraction of the whole archive: never after a cancelled or failed one, never after Extract selected (only part of the archive), and never while the window has unsaved changes.
  • Every part of a split archive goes too: x.z01, x.z02 and x.zip of a spanned zip; x.zip.001, x.zip.002 … of a numbered set, but not a separate x.zip next to them; RAR's x.part1.rar … and x.rar, x.r00 ….
  • The archive window closes, since its archive is in the Trash.
  • Finder's "Put Back" isn't offered for these files. That is how macOS treats any app that moves files to the Trash itself, the App Store-safe way (FileManager.trashItem).

Builds on #353, which it hooks into; until that one is merged, #353's commit shows here too — only the last commit is this one. #330 does this for Finder's actions; #350 lists the differences.

For review: the parts of a split archive are found by name, using the catalog's split types plus RAR's two schemes (ArchiveFiles). New strings (settingsTrashArchiveAfterExtraction and its hint) use the catalog's symbol keys, as since #270.

Part of #350.

How it was verified

  • Tests (ArchiveFilesTests): a plain archive is just its own file; a spanned zip is every part plus its .zip; a numbered set leaves a separate archive of the same name alone; RAR's parts go together in both schemes; names match whatever their case; an opened archive knows its files, also a spanned zip opened at its last part; an archive never saved has none.
  • CI, run locally: swift test --package-path Modules passes, all 668 tests; unsigned Release (MacPacker) and Release Store (MacPacker Store) builds, both universal, pass scripts/check-architectures.sh.
  • Tried in a Debug build: with the setting on, an archive extracted from its window, and one from Finder's Extract Here, goes to the Trash with all its parts, and the window closes; after a cancelled extraction it stays.

Summary by CodeRabbit

  • New Features
    • Extract archives directly beside the archive, with an option to close the archive window afterward.
    • Choose to move archives and their split volumes to the Trash after successful extraction.
    • Use ⌘E to extract an archive and ⌥⌘E to extract selected items.
    • Find extracted items selected in Finder, opening a Finder window when needed.
    • Start extraction beside the archive from Finder, including extraction of selected archive entries.
    • New extraction settings and Finder actions are documented in the MacPacker 1.1.0 changelog.

Before: every Extract button in an archive window asked where to
extract, even when the answer is always "next to the archive". Finder's
Extract Here never asks.

Now: a new setting, Settings ▸ General ▸ "Extract next to the archive"
(off by default). With it on, the window's Extract archive, Extract
selected and the list's Extract… extract straight into the archive's own
folder, without a dialog.

- "Close the window afterwards", a checkbox under it, closes the window
  once the whole archive has been extracted next to it (never while it
  has unsaved changes).
- If MacPacker isn't allowed into that folder yet, it asks for access
  once, as Extract Here does. If that is refused, it asks where to
  extract, as before.
- The result is selected in Finder when the extraction is done, if no
  Finder window is open. If one is open, nothing more opens: Finder can
  only select something in an open window when it sits right in that
  window's folder, and otherwise opens a second window. The result
  simply appears in the window that is there.
- File ▸ Extract archive (⌘E) and Extract selected (⌥⌘E). When the
  setting is off, the toolbar, the list's menu and these shortcuts all
  ask with the same folder dialog, now a sheet on the window.
- Quick Look's Extract buttons follow the setting too. The preview isn't
  allowed to write next to the archive, so it asks the app to do it,
  through MacPacker's url scheme, as the Finder extension does. If the
  app can't be reached, the preview asks where to extract.

For review: the new url action is extractNextToArchive: one archive,
whole or only the entries named by their paths in it, accepted only when
the target is the archive's own folder. It is separate from Finder's
extractHere so that its result is selected the same way as the window's.
The setting is kept in the app group, like smartExtraction, for the
preview to read. ArchiveState.extract(to:smart:) and
extract(items:to:smart:) now return their task, whose value says how the
extraction ended (@discardableResult, so existing callers don't change).
ExtractedItems finds what an extraction added to its folder, leaving out
hidden files such as a .DS_Store Finder writes meanwhile.

📝 Walkthrough

The change adds settings for extracting beside an archive, closing its window, and moving it to Trash. Extraction tasks report outcomes and can select extracted items in Finder. Archive-window and Quick Look actions use shared extraction handling.

Changes: Archive extraction workflow

Layer / File(s) Summary
Extraction settings and release entries
Modules/Sources/Core/AppStorageKeys.swift, MacPacker/Features/Settings/GeneralSettingsView.swift, MacPacker/Localizable.xcstrings, Config/products/macpacker.json, Modules/Tests/CoreTests/ExtractionOutcomeTests.swift
Adds settings for extracting beside the archive, closing the archive window, and moving archives to Trash. Adds related localized strings, release entries, and a test for the default extraction setting.
Extraction outcomes and result discovery
Modules/Sources/Core/ArchiveState.swift, Modules/Sources/Core/Extraction/*, Modules/Tests/CoreTests/ArchiveFilesTests.swift, Modules/Tests/CoreTests/ExtractionOutcomeTests.swift
Archive extraction tasks now return .done, .cancelled, or .failed. Helpers identify archive volumes and extracted items. Tests cover outcomes, result discovery, and volume matching.
Extraction coordination and archive-window actions
MacPacker/Core/ExtractionFollowUp.swift, MacPacker/Core/UrlHandling/AppUrlHandler.swift, MacPacker/Features/ArchiveContentViewer/*, MacPacker/Features/ArchiveWindow/ArchiveCommands.swift, MacPacker/AppDelegate.swift, MacPacker/Core/UrlHandling/AppUrlExtractNextToArchiveHandler.swift
Adds shared destination selection and extraction follow-up. Full extraction can conditionally move archive files to Trash and close the archive window. Archive-window controls and URL extraction use this coordination.
Quick Look and app URL handoff
Modules/Sources/FinderMenu/AppUrl.swift, Modules/Sources/ArchivePreviewUI/*, Modules/Package.swift, QuickLookExtension/Info.plist, Modules/Tests/CoreTests/AppUrlTests.swift
Adds an app URL action for whole-archive or selected-entry extraction beside the archive. Quick Look hands eligible requests to the app and uses folder selection when handoff does not apply. URL parsing and generation receive tests.

Before: "Close the window afterwards" closed the window once an extraction
was done unless it had unsaved changes. Files dragged into the archive
while it ran, and still being read, didn't count yet as changes, so the
window could close and drop them. Separately, when an extraction went
over items that were already there, a hidden one such as .DS_Store could
still be picked for selecting in Finder.

Now:
- The window stays open while added files are still being read
  (ArchiveState.isAddingItems), as it does with unsaved changes.
- Hidden names are left out of what is selected, in every case.

ArchiveExtractor.extractAll and ArchiveState.extract(to:smart:) cannot report
success for incomplete output.
- Around line 1119-1132: Update `ArchiveState.filesOnDisk()` to return an empty
array if listing the archive’s folder fails. Propagate errors from
`FileManager.default.contentsOfDirectory` through `Sandbox.accessSync` and
handle them before calling `ArchiveFiles.files(of:among:splits:)`, so a failed
listing cannot return only the opened volume.

Review comments at @Modules/Sources/FinderMenu/AppUrl.swift:
- Around line 150-151: Update the `AppUrl` initializer’s `items` decoding so a
failed second percent-decoding of any entry rejects the request with

Propagate SWC full-extraction errors.

ArchiveSwcEngine.extract(_:to:passwordResolver:) catches decompression errors, logs them, and returns normally. It also ignores a failed FileManager.default.createFile call. ArchiveExtractor.extractAll therefore completes normally, so ArchiveState.extract(to:smart:) returns .done even when the LZ4 output is incomplete. With the Trash setting enabled, ExtractionFollowUp.trashIfAsked can then move the source archive to the Trash.

The full-extraction API is async throws; this is not an intentional skipped-entry success result.

Right that this can happen, but it is a separate bug, not one this PR adds: ArchiveSwcEngine.extract(_:to:passwordResolver:) swallowed decompression and write errors before this PR and is unchanged here, so a failed whole-archive SWC extraction already reports success today. It needs its own fix with a failing test, which starts with a broken .swc sample in MacPacker-TestArchives, so it stays out of this PR.

@hertza-haeon Thanks for clarifying the scope. The SWC error handling is a pre-existing bug, not a change introduced by this PR. A separate fix with a failing test is appropriate.

Would you like me to open a follow-up issue for error propagation and a regression test using a broken .swc sample in MacPacker-TestArchives?

Learning: In MacPacker, a fix for swallowed full-extraction errors in Modules/Sources/Core/Engine/ArchiveSwcEngine.swift, in ArchiveSwcEngine.extract(_:to:passwordResolver:), should include a failing regression test backed by a broken .swc sample in MacPacker-TestArchives.

Comment thread Modules/Sources/FinderMenu/AppUrl.swift Outdated
Before: the entries of an extractNextToArchive link are encoded twice.
One that survived the first decoding but not the second was silently
dropped. If that left no entries, the link meant "the whole archive", so
a garbled request extracted everything, and could then move the archive
to the Trash when that setting is on (sarensw#354).

Now: an entry that does not decode refuses the whole link
(AppUrl.ParseError.invalidItems). Any app can send these links, so
refusing is the safe answer.

🟡 Minor · Do not report .done after the user cancelled the job. · ArchiveState.swift:1817-1823

Modules/Sources/Core/ArchiveState.swift:1817-1823
🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Do not report .done after the user cancelled the job.

The cancel handler calls cancelFlag.cancel() and task.cancel(). extractAll can still return normally after a cancel. This happens when the cancel arrives after the last progress callback, or when an engine does not check onProgress. The task then sets outcome = .done. ExtractionFollowUp.trashIfAsked then moves the archive to the Trash, and the window can close, even though the user clicked Cancel.

Check the cancel state before you set .done.

Proposed fix
                 try await extractor.extractAll(
                     archiveUrl,
                     archiveTypeId: archiveTypeId,
                     to: target,
                     onProgress: makeEngineProgress(jobId: jobId, cancelFlag: cancelFlag)
                 )
-                outcome = .done
+                // a cancel that came too late to stop the engine still cancels
+                // what follows the extraction (Trash, closing the window)
+                outcome = (Task.isCancelled || cancelFlag.isCancelled) ? .cancelled : .done

Based on learnings: "check Task.isCancelled or handle CancellationError before moving the file or persisting metadata".

After `extractor.extractAll` returns, check `Task.isCancelled` and

either indicates cancellation, and to `.done` otherwise.

Comment thread MacPacker/Core/ExtractionFollowUp.swift
Before: a link with an entry list that was there but empty (items= or
items=,), or had an empty entry in it, parsed as "no entries", which
means the whole archive. A malformed selection could still extract
everything.

Now: only a link without an entry list asks for the whole archive. An
empty list, or an empty entry in it, refuses the link
(AppUrl.ParseError.invalidItems), like an entry that doesn't decode.
Before: Cancel stops an extraction through the engine. If it came just
as the engine finished, or the engine never looked for it, the
extraction still ended as done. "Close the window afterwards", and Move
to Trash (sarensw#354), then acted as if the user hadn't cancelled.

Now: both extractions check for a cancel once the engine is through,
before they say they are done (Task.checkCancellation), and end as
cancelled when there was one. sarensw#339 checks the same before it puts the
result in place.

The test uses a stand-in engine that ignores Cancel and is released only
after the cancel, so the moment is controlled rather than left to timing.
Before: after extracting an archive, it had to be found in Finder and
moved to the Trash by hand.

Now: a new setting, Settings ▸ General ▸ "Move to Trash after
extraction" (off by default). When the whole archive has been extracted
successfully, MacPacker moves it to the Trash, without asking: the Trash
is the way back. This works from the archive window's Extract archive,
from Finder's Extract actions, and from Quick Look's Extract archive
when it extracts next to the archive.

- Only after a complete, successful extraction of the whole archive:
  never after a cancelled or failed one, never after Extract selected
  (only part of the archive), and never while the window has unsaved
  changes.
- Every part of a split archive goes too: x.z01, x.z02 and x.zip of a
  spanned zip; x.zip.001, x.zip.002 … of a numbered set, but not a
  separate x.zip next to them; RAR's x.part1.rar … and x.rar, x.r00 ….
- The archive window closes, since its archive is in the Trash.
- Finder's "Put Back" isn't offered for these files. That is how macOS
  treats any app that moves files to the Trash itself, the App
  Store-safe way (FileManager.trashItem).

For review: the parts of a split archive are found by name, using the
catalog's split types plus RAR's two schemes (ArchiveFiles).
Before: the archive went to the Trash after a finished extraction unless
its window had unsaved changes. Files dragged into the archive while it
ran, and still being read, didn't count yet as changes, so the archive
could go to the Trash with them on their way into it.

Now: it stays while added files are still being read
(ArchiveState.isAddingItems), as it does with unsaved changes.
Before: two cases could leave part of a split archive in the Trash and
part in its folder, useless in both places:
- If the archive's own file couldn't be moved to the Trash, its other
  volumes still were.
- If the archive's folder couldn't be read, its other volumes couldn't
  be found, and the opened file went to the Trash alone.

Now:
- The archive's own file goes first; if it can't, nothing moves.
- When the folder can't be read, ArchiveState.filesOnDisk() names no
  files at all, so nothing moves either.
Before: before moving the archive to the Trash, MacPacker may have to ask
for access to its folder, which can show a panel and wait. While it
waited, the same window could open another archive or start adding
files, and MacPacker then moved whatever the window held by then.

Now: once access is granted, it checks again that the window still shows
the same archive, with no unsaved changes and nothing being added. If
anything changed, the archive stays where it is.

About the review note outside the diff (ArchiveState.swift, "Do not report .done after the user cancelled the job"): right — fixed in 842ab20 (#353). Both extractions now check for a cancel once the engine is through, before they report done, and end as cancelled when there was one. The test uses a stand-in engine that ignores Cancel and is released only after the cancel, so the moment is controlled rather than left to timing.

Before: this pull request added its changelog items to the 1.1.0 block
of Config/products/macpacker.json. 1.1.0 was released on 19 October, so
that block takes no new items.

Now: macpacker.json is as on main. The full items are in the pull
request description, for a new version block, as AGENTS.md asks.

The items of sarensw#353, which this builds on, come out too, as they do in
sarensw#353.
