Changed all Plugin classes and PluginManager to be sealed, preventing further inheritance. This improves code safety and clarifies the intended usage of these classes.
Upgraded several NuGet dependencies across multiple csproj files, including Microsoft.Web.WebView2, Google.Protobuf, MsgReader, bblanchon.PDFiumV8.Win32, and Lib.Harmony. This ensures compatibility with the latest features and bug fixes from upstream packages.
Several .csproj files were updated to use newer versions of dependencies, including Newtonsoft.Json, Microsoft.Web.WebView2, Magick.NET-Q8-AnyCPU, Google.Protobuf, MsgReader, and bblanchon.PDFiumV8.Win32. This ensures compatibility with the latest features and bug fixes from these packages.
Replaced hardcoded icon strings with FontSymbols constants in MoreMenu and converter classes for consistency and maintainability. Removed duplicate FontSymbols class from MidiPlayer and updated usages to reference QuickLook.Common.Controls.
Introduces 'Reopen as source code' and 'Reopen as image preview' options in the MoreMenu for SVG and HTML files, enabling users to switch between ImageViewer and TextViewer plugins. Updates translation files to support new menu items in multiple languages and refactors related plugin code for extensibility.
Updated the menu item and translations to use 'Reopen as source code' instead of 'View source code' across all supported languages for consistency and clarity.
Paths copied to the clipboard are now quoted, and long paths (>= 260 characters) are prefixed with \\?\ to ensure compatibility. This improves reliability when handling long file paths.
Added localized WEBVIEW2_NOT_AVAILABLE messages for ca, he, hi, hu-HU, id-ID, mr, nb-NO, nl-NL, pt-BR, pt-PT, ru-RU, sk, tr-TR, and vi to improve international support in the HTML viewer plugin.
This commit updates various NuGet package references to newer versions across multiple QuickLook plugin and main project .csproj files. These updates include dependencies such as WixToolset.Dtf.WindowsInstaller, UTF.Unknown, FreeTypeSharp, Microsoft.Web.WebView2, Magick.NET-Q8-AnyCPU, Google.Protobuf, MsgReader, HelixToolkit, bblanchon.PDFiumV8.Win32, Melanchall.DryWetMidi, WPF-UI.Violeta, and Lib.Harmony, ensuring the projects use the latest compatible releases.
#### Features
- Uses the latest [github-markdown.css](https://github.com/sindresorhus/github-markdown-css/blob/main/github-markdown.css) file that contains styling support for both dark and light mode.
- Table of Contents has an improved design, and:
- The width can be resized.
- TOC headings are automatically highlighted to help track your position in the file.
- Improved fullscreen layout based on Github.com behavior.
- External links clicked will open in default browser instead of doing nothing.
- Uses [markdownItAnchor](https://github.com/valeriangalliat/markdown-it-anchor) to allow heading anchor links in the file to work.
- Uses [highlight.js](https://github.com/highlightjs/highlight.js) to provide syntax highlighting to codeblocks.
#### Changes
- Made changes to allow the `md2html.html` file to use relative file imports for better maintainability.
- MarkdownViewer can now easily be customized by users by modifying files in `<Quicklook data folder>/QuickLook.Plugin.MarkdownViewer/`
- Caching and `localStorage` is now supported thanks to these changes.
- Prevent default behavior of spacebar scrolling the page, while we use spacebar to dismiss the preview.
- Sets `WebView` `DefaultBackgroundColor` to prevent white flash in dark mode. After the page has loaded, sets `DefaultBackgroundColor` back to white to have the expected default behavior on HTML pages that don't specify any background color.
#### Clean up
- Removed the need for `jQuery`.
- Removed old polyfill code.
