yatli/fvim

This system is a cross-platform, GUI-based implementation of the Neovim editor, built on the .NET 6 and Avalonia frameworks. It provides a modern, MVVM-structured user interface featuring a custom grid renderer, autocomplete completion menu, and crash reporting. The application supports multiple operating systems through platform-specific launchers and app bundle configurations, while also including performance profiling tools for development.

The macOS application bundle now includes an Info.plist defining file associations for Vim, BibTeX, Haskell, MediaWiki, PostScript, Scheme, SQL, Tcl, GTD, reStructuredText, Vimball, VHDL, and Lua files, along with high-resolution display support. Additionally, new launcher scripts are introduced for Linux (fvim-linux-launcher) and macOS (fvim-osx-launcher) to handle environment variables and executable paths, while a .desktop file is added for Linux desktop integration.

The repository was initialized with essential configuration and metadata files. This includes \.vimspector.json\ for debugging setup, \App.xaml\ and \App.xaml.fs\ for the Avalonia application entry point, \GitVersion.yml\ for versioning, \NuGet.config\ for package sources, and various documentation files (\README.md\, \PACKAGING.md\, \LATENCY.md\). Additionally, build and CI/CD infrastructure was added, including \azure-pipelines.yml\ for multi-platform builds, \add\_nuget\_source.ps1\ for dependency management, and \calc\_version.ps1\ for version calculation. The project also includes resource files like \emoji.tsv\ for character support, \fsharp.svg\ for branding, and \app.manifest\ for Windows compatibility.

The application introduces a new Model-View-ViewModel (MVVM) architecture for the user interface. A new \ViewModelBase\ class provides the foundation for all view models, managing position, size, and rendering ticks. Specific view models have been added to handle distinct UI elements: \FrameViewModel\ manages top-level windows and background images; \GridViewModel\ handles the main editor grid, scrollbars, and extmarks; \CursorViewModel\ tracks cursor state and styling; \PopupMenuViewModel\ manages the completion menu; \CompletionItemViewModel\ represents individual completion suggestions with icons; \TitleBarViewModel\ controls the title bar state; and \CrashReportViewModel\ formats crash reports. These components collectively replace the previous rendering logic, enabling better state management and theming support.

ViewModels · high confidence

Added several new view components to the Views directory: a CompletionItem user control for displaying autocomplete suggestions with icons and text; a CrashReport window for handling unexpected exits; a Cursor user control for rendering the editor cursor with animation and opacity controls; a Frame window for the main application layout including title bar and grid hosting; a Grid canvas for rendering text and popups; a PopupMenu user control for the completion list with virtualized items and styled scrollbars; a TitleBar user control for window title and minimize/maximize/close buttons; and a generic ViewBase base class to simplify ViewModel binding and render tick observation.

A new speedscope JSON file has been added to the profiling directory, capturing a performance trace of the FVim.exe process. This data records the call stack and timing of various components including Avalonia UI rendering, input event handling, and Neovim communication, enabling users and developers to analyze application performance and identify bottlenecks.

The application has been upgraded to target .NET 6.0, replacing the previous .NET Core 2.1/3.1/5.0 targets. Additionally, the Avalonia UI framework has been updated to version 0.10.19, and related packages like FSharp.Data and MessagePack have been upgraded to their latest compatible versions.
