Fix Fuckup Recovery Plan

What Happened

Code was stored in /tmp directory which got cleared on restart. Recovered code from decompiled VM binaries.

What Was Lost

The decompiled code has all the logic but:

1. XAML files are gone - they were compiled to C# code
2. AppThemeBinding additions - dark/light mode XAML bindings
3. Original formatting/comments - decompiler output is messy

Recovery Order

Step 1: Fix maui-linux Library First

The library code is recovered and functional. Build and verify:

cd ~/Documents/GitHub/maui-linux-main
dotnet build

Step 2: Recreate Sample XAML with AppThemeBinding

ShellDemo XAML to Recreate

All pages had AppThemeBinding added for dark/light mode:

• AppShell.xaml - FlyoutHeader with:

  • VerticalStackLayout (logo above text)
  • Image with AspectFit
  • BackgroundColor: {AppThemeBinding Light=#F0F0F0, Dark=#2A2A2A}
  • TextColor bindings for labels

• HomePage.xaml - AppThemeBinding for:

  • BackgroundColor
  • TextColor
  • Button colors

• ButtonsPage.xaml - AppThemeBinding colors

• TextInputPage.xaml - Entry/Editor theme colors

• PickersPage.xaml - Picker theme colors

• ProgressPage.xaml - ProgressBar theme colors

• SelectionPage.xaml - CheckBox/Switch theme colors

• ListsPage.xaml - CollectionView theme colors

• GridsPage.xaml - Grid theme colors

• AboutPage.xaml - Links with tap gestures, theme colors

• DetailPage.xaml - Theme colors

TodoApp XAML to Recreate

• TodoListPage.xaml - AppThemeBinding for:

  • Page background
  • List item colors
  • Button colors

• TodoDetailPage.xaml - Theme colors

• NewTodoPage.xaml - Theme colors

XamlBrowser XAML to Recreate

• MainPage.xaml - WebView container with theme

AppThemeBinding Pattern

All XAML used this pattern:

<Label TextColor="{AppThemeBinding Light=#333333, Dark=#E0E0E0}" />
<Grid BackgroundColor="{AppThemeBinding Light=#FFFFFF, Dark=#1E1E1E}" />
<Button BackgroundColor="{AppThemeBinding Light=#2196F3, Dark=#1976D2}" />

FlyoutHeader Specifics

The FlyoutHeader had this structure:

<Shell.FlyoutHeader>
    <Grid BackgroundColor="{AppThemeBinding Light=#F0F0F0, Dark=#2A2A2A}"
          HeightRequest="160"
          Padding="15">
        <VerticalStackLayout VerticalOptions="Center"
                             HorizontalOptions="Center"
                             Spacing="8">
            <Image Source="openmaui_logo.svg"
                   WidthRequest="70"
                   HeightRequest="70"
                   Aspect="AspectFit"/>
            <Label Text="OpenMaui"
                   FontSize="20"
                   FontAttributes="Bold"
                   HorizontalOptions="Center"
                   TextColor="{AppThemeBinding Light=#333333, Dark=#E0E0E0}"/>
            <Label Text="Controls Demo"
                   FontSize="12"
                   HorizontalOptions="Center"
                   TextColor="{AppThemeBinding Light=#666666, Dark=#B0B0B0}"/>
        </VerticalStackLayout>
    </Grid>
</Shell.FlyoutHeader>

User can take screenshots of running app to recreate XAML:

1. ShellDemo Flyout open - Light mode
2. ShellDemo Flyout open - Dark mode
3. Each page - Light and dark mode
4. TodoApp - Light and dark mode

Build & Deploy Commands

# Build library
cd ~/Documents/GitHub/maui-linux-main
dotnet build

# Build ShellDemo
cd ~/Documents/GitHub/maui-linux-samples-main/ShellDemo
dotnet publish -c Release -r linux-arm64 --self-contained

# Deploy
sshpass -p Basilisk scp -r bin/Release/net9.0/linux-arm64/publish/* marketally@172.16.1.128:~/shelltest/

# Run
sshpass -p Basilisk ssh marketally@172.16.1.128 "cd ~/shelltest && DISPLAY=:0 XAUTHORITY=/run/user/1000/.mutter-Xwaylandauth.* ./ShellDemo"

CRITICAL RULES

1. NEVER use /tmp - always use ~/Documents/GitHub/
2. Commit and push after EVERY significant change
3. Only push to dev branch - main has CI/CD actions
