GacUI 1.0

• Cannot change column size during datagrid's bounds changing, which is by designed and this could be solved by calling InvokeInMainThread. But new feature for solving this is under considering
  • Considering GuiBindableDataGrid updating columns' sizes according to configuration automatically, and call GuiControl::InvokeOrDelayIfRendering (indirectly) inside DataColumn::NotifyAllColumnsUpdate when necessary.
  • Like a table, a column can use Absolute, Draggable and Percentage to specify a column size. Only when a column is draggable, users can use their mouse to change the size of a column, and then trigger IColumnItemView::SetColumnSize
• Consider drag and drop support, with column drag and drop
• New item arranger that can accept a GuiRepeatCompositionBase
• let X = Y in (F(X.a.b.c)) reports X does not exist in the current scope in binding property value
  • while F((let X = Y.a.b).c) works
• Update Release
• New default control templates with animation, written in XML generated C++ code.
• A window can be called to update all its controls' and components' template
• Tutorials use the new default control templates
• Update Release
• Fix GacGen reports only "error dumping resource file" while the resource file contains some syntax errors preventing GacGen from reading it
  • Unable to repro

ON GOING: Document repo

GacUI 2.0

Vlpp

• Regex supports UTF-16 (instead of UCS-2) on MSVC.
  • Always convert to UTF-32 internally (vl::regex::Utf32Reader).
• Redesign vl::parsing.
  • No need to specify ambiguity
  • Will print all ambiguous cases and marked AST node
  • ToString with hints and custom options
  • Print diff when updating AST (for IDE)
  • All existing features and backward compatible interface design
• Binary ITypeDescriptor provider format.
• API to import and export fake types (ITypeDescriptor that cannot be executed)
• Interfaces for collections types like IReadableCollection<T>
• Reflectable interfaces like IReflectableReadableCollection<T>, inherits from IReadableCollection<T> and IReadableCollection<Value>

Workflow

• Don't create IValueList if apply {1 2 3} on List<int> argument.
• Support <category>name identifier, make generated code re-parsable.
• Recognize collection interfaces instead of collection entities.
  • Reconsider how to implement collection creating code in Workflow.
• Move to new ParserGen.
• WorkflowCompiler.exe (x32/x64)
  • Enable external symbols
  • Compile
  • Binary Output (full assembly or types only)
  • C++ Codegen (x32/x64)

(probably not do)

• Macro
• Context-Grammar Sensitive Macro
• Virtual function
• Class implements interface

GacUI

Before 1.0 (Optional)

• <eval Ref="Name"/> and <eval Eval="expression"/> tags
• Enable Workflow script template for IGuiInstanceLoader written in text
• INativeImage::SaveToStream handle correctly for git format. It is possible that LoadFromStream need to process diff between git raw frames.

After 1.0

• Use collection interfaces on function signatures.
• Move to new ParserGen.

Cross Platforms

• Ncurses on Ubuntu
• macOS
• Web Assembly

Graphics

• MetaImageElement and MetaImage data structure
• Remove PolygonElement
• Default non-text element renderer using MetaImageElement
• Replacing GDI and D2D non-text element renderers
• Meta3DElement and Meta3D data structure
• Default Meta3DElement renderer using MetaImageElement with a surface sorting based algorithm

Controls

• Chart
• Dock Container
• Touch support

Binders

• Other languages
  • XML still generate C++ files, and they need to be compiled to an appropriate form.
  • Other programming languages doesn't access GacUI objects, instead they implement view model interfaces that defined in XML.
  • Users need to compile C++ code by themselves.
  • Users are not required to write C++ code, but they can.
  • Users can add attributes in XML defined interfaces, so that GacGen can generate a list of them. After that, by reading generated workflow assembly files, glue code can be generated so that users can implement required view model interfaces directly. I will provide some tools for listed languages.
  • Resources need to be generated in C++ files, because other languages cannot access GacUI objects, which means they cannot load resources manually.
  • Languages:
    • JavaScript / TypeScript through Web assembly
    • .NET (core?) through dll
    • Python through dll

GacGen.exe

• Enable linking to external symbols
• In the final pass, only workflow scripts are printed
  • Use WorkflowCompiler.exe to do codegen externally

GacStudio.exe

DocTools

• Rewrite in C++
