They outline the specific adaptations made to Verso's API surface and the necessary modifications to Tauri's internal workings to accommodate this new browser engine. While acknowledging the experimental nature of the integration, the post emphasizes the potential benefits of using Verso, such as its modern architecture and future-proof design.

  The blog post concludes by highlighting that the integration is still in its early stages, with considerable work remaining before it can be considered production-ready. Furthermore, the authors stress that the primary goal of this experiment is to explore the feasibility and potential benefits of using Verso, rather than immediately replacing WebKit. They express optimism about the future of this integration and invite community feedback and contributions to further the development of this potentially groundbreaking combination of technologies. The overall tone of the post suggests a cautious yet enthusiastic exploration of a promising avenue for enhancing Tauri's capabilities and ensuring its long-term viability in the evolving landscape of web and desktop application development.

  Verbose tl;dr

  Someone has rendered the entirety of the original Doom (1993) game, including all levels, enemies, items, and even the intermission screens, as individual images within a 460MB PDF file. This allows for a static, non-interactive experience of browsing through the game's visuals like a digital museum exhibit. The PDF acts as a unique form of archiving and presenting the game's assets, essentially turning the classic FPS into a flipbook.

  A highly inventive individual, going by the online moniker "b33f", has undertaken a fascinating project: the meticulous conversion of the entirety of the groundbreaking 1993 first-person shooter video game, Doom, into the portable document format (PDF). This is not simply a document about Doom, but rather a functional, albeit unconventional, rendition of the game itself. The PDF file, hosted online for public access, leverages the surprising capabilities of the PDF specification to emulate a rudimentary form of interactive gameplay within the confines of a document typically associated with static text and images.

  The project utilizes a series of intricately designed pages, each representing a distinct game state or a minor incremental change within the game world. Rather than employing traditional animation or code execution, the "gameplay" progresses by manually navigating through these numerous pages, simulating movement, actions, and even the passage of time within the Doom environment. Each page is a static snapshot, depicting the game's visuals at a specific moment, including elements such as the player's perspective, enemy positions, and the state of the environment. Progression is achieved by clicking hyperlinks embedded within the PDF, each link corresponding to a potential player action, like moving forward, turning, or firing a weapon. Clicking a link transports the user to the page representing the outcome of that action, effectively creating a painstakingly constructed illusion of interactive experience.

  While this approach drastically deviates from the original game's real-time dynamics and smooth animation, it serves as a remarkable demonstration of the often-overlooked flexibility inherent in the PDF format. The project is not meant to be a practical replacement for playing the original Doom, but rather an intriguing experiment and a testament to creative problem-solving. It showcases how a seemingly inflexible format can be manipulated to achieve unexpected results, blurring the lines between document and application, and offering a unique, albeit cumbersome, way to experience a classic piece of gaming history within the familiar confines of a PDF reader. The sheer volume of pages required to represent even a small portion of the game highlights the dedication and effort invested in this curious undertaking.
