- Replace SystemParameters with Avalonia screen API in CUE4ParseViewModel
- Rewrite Resources.xaml for Avalonia Fluent theme (~2150→290 lines)
- Extend CommitMessageConverter with HasDescription parameter support

* fix: address review findings for PR #85

- C1: Fix ToolTip syntax (TextBlock.ToolTip → ToolTip.Tip) in tree view
- C2: Add Fill binding to folder icons via ConverterParameter=Brush
- C3: Convert AddEditDirectoryCommand.ShowDialog() to async with owner
- M1: Convert keyed Style → ControlTheme + Theme= in all consumers
- M2: Fix CommitControl badge overlap (Latest/Current mutual exclusivity)
  Add FallbackValue=False for null-safe Asset.IsLatest binding
- M3: Add TODO(P4-004) markers for OpenFileDialog/SaveFileDialog
- M4: Implement IDisposable on CompositeCollection; dispose on replace
- PR: Add UrlToBitmapConverter for HTTP avatar image loading
- PR: Fix ContextMenu DataContext in GameFilesTabControl ContentTemplate
  Restore 'Disable Alpha Channel' toggle (NoAlpha binding)
- PR: Replace ElementName=TabControlName with direct DataContext bindings
- PR: TreeViewItemBehavior uses GetObservable(IsSelectedProperty) with
  proper IDisposable subscription cleanup
- S1: Clarify UpdateViewModel grouping TODO (non-DataGrid limitation)
- S2: Cache compiled Regex in SearchViewModel.ItemFilter
- m3: Implement TabItemFillSpace with HorizontalAlignment=Stretch

Also updates FolderToGeometryConverter to support ConverterParameter

* fix: address review #2 findings on PR #85

- M1/m1/m2: UrlToBitmapConverter — sync download with ConcurrentDictionary
  URL cache, 4-space indent, doc comment noting async limitation
- M2: Remove duplicate IsVisible attribute on Latest badge Border
  (MultiBinding property element takes precedence; attribute was dead code)
- m3: Add TimeSpan.FromSeconds(1) timeout to user-input Regex construction
- PR: ZIndex → Panel.ZIndex in SearchTextBox.xaml (Avalonia attached prop)
- PR: ShadowEffect comment updated to reflect key removal (no consumers)
- PR: CustomSeparator Tag TextBlock hidden when empty via
  StringConverters.IsNotNullOrEmpty (eliminates unwanted 10px margin)
- PR: CustomVerticalSeparator BasedOn changed from default Separator to
  CustomSeparator (preserves tagged template inheritance from WPF)
- PR: AddEditDirectoryCommand — early return when owner is null instead
  of silently skipping dialog
- PR: CompositeCollection.Count — skip non-ICollection sources instead
  of O(n) enumeration fallback

* Fix Avalonia parity gaps in updates, styles, and dialogs

* fix: address parity review follow-ups and unresolved PR comments

* Fix remaining PR review thread regressions

* Address review findings: thread safety, Linux guards, indentation, and cleanup

- [C1] Fix LoadCoAuthors thread race by snapshotting Commits before Task.Run
- [M1] Remove IsAsync=True (WPF-only) from Avalonia bindings
- [M2] Add OperatingSystem.IsWindows() guard for Win32 OpenFileDialog
- [M3] Add null-safety for Application.Current in PlayPause converter
- [N1] Add BrushTransition to HighlightedCheckBox for animation parity
- [N2] Dispose TreeViewItem subscriptions on DetachedFromVisualTree
- [N3] Fix SelectionMode converter: only Multiple uses multi-select
- [S1] Simplify AddEditDirectoryCommand owner-null to early return
- [S3] Remove dead WPF trigger comments from UpdateView.xaml
- [S4] Add 10s timeout to UrlToBitmapConverter HttpClient
- PR: Reformat UrlToBitmapConverter to 4-space indentation
- PR: Catch RegexMatchTimeoutException in SearchViewModel filter

* Fix review round 2: ActualWidth→Bounds, IsAsync removal, FindAncestor xmlns, misc

Critical:
- C1: Replace ActualHeight/ActualWidth with Bounds.Height/Bounds.Width
  in UpdateView, MainWindow, SettingsView, DirectorySelector (Avalonia
  has no ActualWidth/ActualHeight properties)
- C2: Remove remaining IsAsync=True from SearchView.xaml and
  AudioPlayer.xaml (WPF-only, no-op in Avalonia)

Major:
- M1: Add xmlns:views for FModel.Views and replace dotted sub-namespace
  local:Views.SettingsView with views:SettingsView in all 23
  FindAncestor bindings (avoids ambiguous XAML type resolution)
- M2: CompositeCollection.Count now skips non-ICollection sources
  instead of enumerating them (O(1) for current callers)

Minor:
- N1: Add Application.Current null guard in FolderToGeometryConverter
  (matches PlaybackStateToPlayPauseConverter pattern)

Suggestions:
- S1: UrlToBitmapConverter.LoadAsync now cleans up _inFlight on all
  exit paths (defense-in-depth for exceptional failures)
- S2: Add comment in CommitMessageConverter documenting interaction
  with LoadCoAuthors co-author cleanup

* fix: merge resource dicts, regex cache, handler cleanup, null-init

- Merge Colors.xaml, Icons.xaml, Resources.xaml into App.xaml so
  StaticResource/DynamicResource lookups resolve at runtime
- Cache invalid regex state in SearchViewModel to avoid repeated
  recompilation on every filter invocation
- Detach DetachedFromVisualTree handler in TreeViewItemBehavior
  when IsBroughtIntoViewWhenSelected is set to false
- Fix LoadingModeToSelectionModeConverter doc to match behavior
- Initialize Commit/Author backing fields with null! to satisfy
  non-nullable contract before JSON deserialization
- Add Debug.Fail in CompositeCollection.Count for non-ICollection
  sources to surface unexpected usage in development

* fix: load missing resource dictionaries, remove dead style refs, fix using

- App.xaml: add ResourceInclude for FileContextMenu, FolderContextMenu,
  and TiledExplorer/Resources.xaml so StaticResource lookups resolve at
  runtime (C1 fix)
- TiledExplorer/Resources.xaml: remove ContextMenu Setters from both
  TiledExplorer and AssetsListBox styles; Avalonia does not support
  x:Shared="False", so the shared instance would break when two
  ListBoxes reference the same ContextMenu. ListBoxItemBehavior already
  handles assignment programmatically via TryFindResource on right-click.
- SettingsView.xaml: remove 11 references to undefined TextBoxDefaultStyle;
  HotkeyTextBox inherits FluentTheme TextBox styling by default (C2 fix)
- LoadingModeToSelectionModeConverter.cs: add missing 'using FModel' for
  ELoadingMode resolution (M1 fix)

* fix: convert Resources.xaml to Styles root, restore toggle button states

- Resources.xaml: change root from <ResourceDictionary> to <Styles> so
  StyleInclude in App.xaml correctly loads an IStyle-implementing element.
  All keyed resources (ControlThemes, converters) moved into
  <Styles.Resources>; selector-based styles (audio controls, FoldingMargin)
  are direct <Styles> children.
- AssetsExplorerToggleButtonStyle: restore IsChecked-dependent behavior
  using Avalonia selectors. :checked shows FolderIconAlt + accent background,
  :unchecked shows AssetIcon + default background. Tooltip shows hotkey.
- MainWindow.xaml: add Classes="AssetsExplorerToggle" to the toggle button
  so the selector-based checked/unchecked styles match.

* Fix Round 7 review findings: ControlTheme, ToolTip.Tip, dead code

- C1: Convert keyed Styles to ControlTheme in TiledExplorer/Resources.xaml,
  update Style= to Theme= in MainWindow.xaml, convert CustomRichTextBox
  to auto-applying Style Selector in Resources.xaml
- M1: Fix ToolTip= to ToolTip.Tip= across SearchView, SettingsView,
  AudioPlayer, and DirectorySelector (22 occurrences)
- m1: Remove duplicate _inFlight.TryRemove in UrlToBitmapConverter.cs
- m2: Remove dead Result property from CustomDir.xaml.cs
- S2: Remove unused InvertBooleanConverter from Resources.xaml

* Fix PR review findings: image column collapse, thread safety

- Add HasImageToColumnSpanConverter so AvalonEditor spans all columns
  when HasImage is false, preventing unused blank space from the image
  column width (Resources.xaml GameFilesTabControl ContentTemplate)
- Marshal LoadAssets and LoadCoAuthors collection/property mutations to
  Dispatcher.UIThread.InvokeAsync for explicit thread safety

* fix: reformat HasImageToColumnSpanConverter to 4-space indentation

* fix: map All/AllButNew/AllButModified/AllButPatched to multi-select

LoadingModeToSelectionModeConverter only mapped Multiple to
SelectionMode.Multiple. The original WPF DataTriggers also enabled
Extended selection for All, AllButNew, AllButModified, and
AllButPatched modes. Add those mappings to restore parity.

FModel Linux — Unreal Engine Archives Explorer for Linux

CI Status Latest


This is an unofficial Linux port of FModel, originally created by Asval (4sval) and contributors. It is not affiliated with or endorsed by the upstream project or its maintainers. Please do not report Linux-port-specific issues upstream.

Description

FModel Linux is a Linux port of FModel — an archive explorer for Unreal Engine games. It uses CUE4Parse as its core parsing library, providing robust support for the latest UE4 and UE5 archive formats, along with a comprehensive set of tools for previewing and converting game packages.

This fork replaces the Windows-only WPF UI stack with Avalonia UI and removes other Windows-specific dependencies to enable native Linux support. It is maintained by r6e.

Installation

Installation instructions for the Linux port are available in the project wiki (work in progress).

For the upstream Windows release, refer to the official FModel installation guide.

Supporting the Upstream Project

This fork does not accept donations. If you find FModel valuable, please consider supporting the original FModel project and its contributors.
