Tab behaviour buggy

Hello,
I started using AvaloniaEdit recently.
Everytime I try to use the tab key after writing a char it creates weird symbols.
It looks like this (AvaloniaEdit demo):

I tabbed two times, than wrote t1 and than used tab another multiple times which creates this symbols

I tried both on Windows and Linux with same results.
Anything I can do about that?

HighlightingDefinitionTypeConverter does not work

i. e.

<AvalonEdit:TextEditor SyntaxHighlighting="XML"/>

throws exception

NuGet package?

It would be useful. Not necessary nuget.org but maybe myget.

NullReferenceException in AvaloniaEdit.Rendering.TextView.BuildVisualLine

I'm getting it with version from nuget on Linux at startup and on Windows after trying to resize the window

How to use TextEditor?

Can you write Readme, and push any examples, pls? With latest version of avalonia i have "exception | {"Method not found: 'System.Action Avalonia.Controls.Primitives.ILogicalScrollable.get_InvalidateScroll()'."} | System.MissingMethodException". With latest stable avalonia version i had invisible control but IsVisible was true.

MissingMethodException is thrown

I tried to add AvaloniaEdit nuget into a project. Using Avalonia.Desktop 0.9.2
Project template is created from the mvvm template provided by avalonia.

However, the project fails to run with the following exception:
Unhandled exception. System.TypeInitializationException: The type initializer for 'AvaloniaEdit.Editing.TextArea' threw an exception.

Here is the entire stack trace:

I know the demo in this repo is working, but I haven't the slightest clue of what I'm missing to make it work.

With further investigation, I noticed that the nuget version uses a constructor for Pen that doesn't exist anymore:

private static Pen CreateFrozenPen(IBrush brush)
    {
      return new Pen(brush, 1.0, (DashStyle) null, PenLineCap.Flat, PenLineCap.Flat, PenLineCap.Flat, PenLineJoin.Miter, 10.0);
    }

The github code of AvaloniaEdit:

private static Pen CreateFrozenPen(IBrush brush)
        {
            var pen = new Pen(brush);
            return pen;
        }

Update Avalonia to 0.8?

I updated Avalonia to 0.8 and now an app is crashing with the following exception :(

System.MissingMethodException: Method not found: 'Avalonia.Size Avalonia.Media.FormattedText.Measure()'.
  at at AvaloniaEdit.Text.TextLineRun.CreateRunForText(StringRange stringRange, TextRun textRun, Double widthLeft, Boolean emergencyWrap, Boolean breakOnTabs)

Leak in 0.10.0-preview1

There seems to be some sort of leak in AvaloniaEdit 0.10.0-preview1 with Avalonia 0.10.0-preview3 (or also with Avalonia 0.10.0-preview1).

While editing a moderately large document, the memory usage goes up very quickly at every redraw.

To reproduce, open the AvaloniaEdit demo, paste in it some text (e.g. 5 paragraphs of Lorem Ipsum from https://www.lipsum.com/) and then, using the mouse, quickly select and deselect large portions of text. On my machine, after about 10 seconds of this, the memory usage goes up from ~150MB just after starting the program, to over 500MB.

The leak does not seem to happen with AvaloniaEdit 0.9.0-preview1 and Avalonia 0.9.12.

Update auto builds

The latest nuget version is from October 15, 2019. The appveyor version is up to date but all demo artifacts are empty zip files. Sadly there is no way for developers to subscribe to appveyor builds.

There isn't too much activity on this repo. Can it be possible to auto update the nuget package on every commit? This is kind of useful when subscribed also to Avalonia releases (the current nuget package misses all the "Update avalonia" commits).

I've encountered such behavior in AvaloniaILSpy about field:

Implement word wrap

If I modify the demo app to enable word wrap, text still doesn't wrap to the next line:

    <AvalonEdit:TextEditor Name="Editor"
                           Margin="30"
                           HorizontalScrollBarVisibility="Auto"
                           VerticalScrollBarVisibility="Visible"
                           WordWrap="true"
                           TextBlock.FontSize="30" />

I also tried setting a Width on the control as well and it had no affect on word wrap. Is there something I'm missing here? This is a pretty critical feature for a text editor.

AppendText doesn't update scroll area; Select all -> Delete doesn't either

Issue

Something in the text area isn't updating properly when using AppendText (or otherwise manipulating the text). I chatted with @danwalmsley in Discord about this, but we didn't get to the bottom of it. Basically, my app uses AvaloniaEdit as a console and appends text a bunch; however, the user can never see all the text that gets added because the scrollbar breaks and it appears as though there is nothing more to see. If you highlight/select the text, though, the UI updates nicely and you can view everything as you'd expect.

The fact that this is visible with the scrollbar may just be a red herring and not the actual issue.

Repro

This uses Avalonia CI build 8974, but you should be able to repro with 0.10.0-preview1 too.

https://github.com/Deadpikle/AvaloniaEdit/tree/bug/scrollbar

Start demo app
Click 'Append text test' a bunch, slowly. Watch the scrollbar not update.
Click in the text anywhere and select. The scroll area updates, as evidenced by the scrollbar.

Start demo app
Click 'Append text test' a bunch of times (fast or slow)
Control + A -> Delete key to remove all text
Scroll bar is still there and you can scroll with mouse wheel even though nothing is there

Notes

In Discord, I reported that moving TextView.SetScrollOffset's ScrollOffsetChanged call outside of its if statement fixed things. This was incorrect. It does not fix things.

Handle scrolling

Most of the scrolling code is currently commented out since Avalonia doesn't have IScrollInfo. Possibly ILogicalScrollable could be made to work here.

Most of the code is in TextView (I deleted much of the scroll code, may need to copy again from AvalonEdit).

Delete key doesnt work

Missing member exception

Biding content

This is ask to help.
Try to create dependency property like this.
https://github.com/CreateLab/NeBrowser/blob/master/Controls/BindableTextEditor.cs#L29
And try to bind like this
https://github.com/CreateLab/NeBrowser/blob/master/Views/MainWindow.xaml#L199
But has an exception in runtime

MainWindow.xaml(199, 33): [XAMLIL] Unable to find suitable setter or adder for property BindingText of type NeBrowser:NeBrowser.Controls.BindableTextEditor for argument Avalonia.Markup:Avalonia.Data.Binding, available setter parameter lists are:
System.String Line 199, position 33.

I have no ideas how to fix it.

Performance Degradation on 0.10.0-preview2

After upgrading a project which uses AvaloniaEdit from 0.9.0 to 0.10.0-preview2 things are working, well, 10 times slower. Using Ubuntu 18.04 LTS KDE, the following markup is used to instantiate and draw the editor:

<avaloniaEdit:TextEditor
    FontFamily="Ubuntu Mono"
    x:Name="AvaloniaEdit"
    HorizontalAlignment="Stretch"
    VerticalAlignment="Stretch"
    HorizontalScrollBarVisibility="Auto"
    VerticalScrollBarVisibility="Auto">
    <avaloniaEdit:TextEditor.Options>
        <avaloniaEdit:TextEditorOptions 
            ConvertTabsToSpaces="True"
            IndentationSize="4"
            ShowTabs="True" />
    </avaloniaEdit:TextEditor.Options>
</avaloniaEdit:TextEditor>

This is how it was working with 0.9.* (absolutely fast):

This is how it works after the upgrade to 0.10.0-preview* (almost a slideshow):

Selection with mouse does not work

I am using the AvaloniaEdit 0.6.0 package.

I am using Avalonia with MVVM, and my XAML is this simple:

<ae:TextEditor ShowLineNumbers="True" FontSize="14" FontFamily="Consolas" Document="{Binding SourceDocument}" SyntaxHighlighting="C#" />

When trying to select some text in the text view using the mouse, nothing happens. I cannot even place the caret using the mouse... Am I missing something? I would expect this to work out of the box.

Help - What is the best way to "add a breakpoint"?

Hello,
I would like to "add a visual breakpoint" in my file, but I don't know which classes to change. Is it possible to achieve this without changing the current code base? I want to be able to toggle a square/ball in the margins.
I saw a code that would do something similar in the past, but I can't find it again.

Hints?

Thanks!

Fix copy/paste shortcuts on mac using ctrl instead of cmd

The keyboard shortcuts on mac appear to be using the ctrl key instead of the more common cmd. While the windows ones still work on the mac, it does cause a bit of confusion since the Avalonia controls use cmd and the AvaloniaEdit control uses ctrl.

I asked about this in the chat:

Nikita Tsukanov@kekekeks Apr 09 22:55
Hotkeys are probably still set to Ctrl+C instead of Cmd+C
AvaloniaEdit needs to use hotkey info from AvaloniaLocator.Current.GetService<PlatformHotkeyConfiguration>();

TextEditor throws an exception on startup

On startup I get the following exception:

MissingMethodException: Method not found: 'Void Avalonia.Media.Pen..ctor(Avalonia.Media.IBrush, Double, Avalonia.Media.DashStyle, Avalonia.Media.PenLineCap, Avalonia.Media.PenLineCap, Avalonia.Media.PenLineCap, Avalonia.Media.PenLineJoin, Double)'.

My xaml only contains <AvaloniaEdit:TextEditor/>. I'm running Avalonia 0.9.12. Any suggestions?

Fix copy/paste shortcuts on mac using ctrl instead of cmd (part 2)

The keyboard shortcuts on mac appear to be using the ctrl key instead of the more common cmd. While the windows ones still work on the mac, it does cause a lot of confusion since the Avalonia controls use cmd and the AvaloniaEdit control uses ctrl, so users are never sure which one to use.

There was a previous ticket about this that got closed. And it looks like a fix was attempted for this, but a lot of the changes got reverted since it possibly broke the shortcuts for Windows.

Exception in the designer when I have AvalonEdit control

The following error can be avoid by setting IsVisible to false. (I set it to true in .cs).
Or be setting MaxWidth.

Update Avalonia

Hi and thanks for all the hard work on this project!
It seems that this codebase is using Avalonia 0.9.0-preview1 ( https://github.com/AvaloniaUI/AvaloniaEdit/blob/master/build.cake#L158 )
This is missing several bugfixes in later versions of Avalonia. Notably a fix in 0.9.2 which causes a hard crash at startup for ILSpy on NixOS .
I'm not familiar with this codebase or even Avalonia, is this as easy as changing that version in the Cake file? Would the tests catch any breaking changes (hopefully there are none)?

how to specify custom themes/color schemes?

BraceFoldingStrategy doesn't work like AvalonEdit

I try to use BraceFoldingStrategy.cs in my projet but the result is not usable as on AvalonEdit.

public static void AddBraceFolding(this TextEditor textEditor)
{
    var foldingManager = AvaloniaEdit.Folding.FoldingManager.Install(textEditor.TextArea);
    var foldingStrategy = new SharpDevelop.BraceFoldingStrategy();
    textEditor.TextChanged += (s, e) => foldingStrategy.UpdateFoldings(foldingManager, ((TextEditor)s).Document);
}

// And juste call it in InitializeComponent like 'myDocumentTextEditor.AddBraceFolding();'

Scroll not synchronized

Scrolling from the editor syncs with the scroll bar, but not the other way around.

There's also an issue when hitting Enter to add a new line (scroll gets out of sync with text).

Weird symbol on Ctrl + Del

Also, this combination does not work properly.

Is there a way to underline text like in AvalonEdit?

...TextRunProperties.SetTextDecorations(TextDecorations.Underline);

I see that TextDecorations.Underline exists, but I am not sure how to use it.
For context: I am writing a custom colorizer by implementing DocumentColorizingTransformer.
Thank you!

Cursor position for last line displays below last line when content requires scrolling

If the scrollbar is active due to the content being larger than the text area, the text cursor shows an extra 30 pixels below where it should. This only happens when editing the last line too. Editing any other line works correctly.

Here's what the AvaloniaEdit.Demo shows

The problem is even worse for regular sized fonts too (size 16 here). Even editing the 2nd to last item has problems at this size. Note the sidebar doesn't even line up anymore.

Poor performance with large files

If you open a file with a large number of lines performance is very slow.

It builds the visual lines for the entire document twice.
navigating up and down also seems to run a loop over all the lines in the document, needs to be limited to just those being displayed.

Can demo and repro when your back @aelij

Delete() does not work in the same context with Cut()

I need to remove line without rewriting the clipboard. And i cant understand why field IsReadOnly must be false to use Cut(). I'm not an expert, but I think it isnt normal.

Visual glitch at the start of the line

Reproducible on Ubuntu + .NET Core.

Strange offset between text that has formatting applied and plain text

If I run a line transformer colorizing my text afterwards everything is slightly offset, and also selection and results from BackgroundGeometryBuilder.GetRectsForSegment are slightly out.

Above image demonstrates issue!

the text xxxx has no colorizing applied, and background renderer positions match,

Control rendering glitch

Hello.

If I move applications window which contains AvaloniaEdit control to my second monitor with different resolution, control starts to expand (every second rendered control is start to get larger and larger, like if you use windows magnifier). You can reproduce it by using AvaloniaEdit.Demo application, or sample from attachments (it is the same demo actually).
At start:

When I move it to another monitor:

AvaloniaApplication2.zip

Checking Scrolled to End with WordWrap=true

I'm customizing the scroll function which can support as follow:

If I scroll to the end, the function ScrollToEnd() will be executed repeatedly.
If I scroll up (not at End position), the ScrollToEnd() will not be executed.

The following is what I added into TextEditor.cs:
AddHandler(ScrollViewer.ScrollChangedEvent, new ScrollChangedEventHandler(ScrollChanged));

private void ScrollChanged(object sender, ScrollChangedEventArgs e)
{
	TextView textView = TextArea.TextView;

       double lineHeight = textView.DefaultLineHeight + 1;

	bool isAtEnd = textView.VerticalOffset + textView.ActualHeight + lineHeight >= textView.DocumentHeight;
	if( isAtEnd )
	{
		ScrollToEnd();
	}
}

I got a problem with WordWrap=true. Are there any solutions I can address this problem?

Thanks.
