About

Hi there, Zero Stars here.<p>I recently published some new work to Hokusai Pocket, which is a cross-platform binary made on top of raylib and MRuby that runs GUIs from ruby scripts.<p>License?<p>MIT!<p>How does it work?<p>The binary is available on the GitHub releases page: <a href="https:&#x2F;&#x2F;github.com&#x2F;skinnyjames&#x2F;hokusai-pocket&#x2F;releases&#x2F;tag&#x2F;0.6.1" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;skinnyjames&#x2F;hokusai-pocket&#x2F;releases&#x2F;tag&#x2F;0...</a><p>You can download the binary on x86 Windows, OSX, or Linux, and run your GUI application with<p>hokusai-pocket run:target=&quot;&lt;your_hokusai_app.rb&gt;&quot;<p>For a little bit of a hello world, I started a photoshop clone<p><a href="https:&#x2F;&#x2F;github.com&#x2F;skinnyjames&#x2F;hokusai_demo_paint" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;skinnyjames&#x2F;hokusai_demo_paint</a><p>Also a little game<p><a href="https:&#x2F;&#x2F;github.com&#x2F;skinnyjames&#x2F;pocket-squares" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;skinnyjames&#x2F;pocket-squares</a><p>Docs &#x2F; Help?<p>The docs are in progress, but the old docs for the CRuby version express some of the basic ideas around the project. <a href="https:&#x2F;&#x2F;hokusai.skinnyjames.net&#x2F;docs&#x2F;intro" rel="nofollow">https:&#x2F;&#x2F;hokusai.skinnyjames.net&#x2F;docs&#x2F;intro</a><p>(I&#x27;m also available to answer questions in between slinging pizza)<p>Deps?<p>Hokusai pocket currently uses<p>* libuv for offloading cpu intensive tasks to a worker pool to prevent blocking the UI thread, and I plan to integrate some libuv networking as well.<p>* raylib for backend graphics &#x2F; I&#x27;ve also built with SDL on arm64 to run applications on my pinephone<p>* NativeFileDialog for the lovely integration into filesystem.<p>* MRuby for running or embedding the scripts<p>* tree-sitter for the custom template grammar (Although templates can be built with ruby)<p>Anyway, I hope you get a chance to try it. If you make something cool AND have docker installed, you can also publish your work as single binary<p>`hokusai-pocket publish:target=&lt;your cool program.rb&gt;`<p>Would love feedback, apps, and help with documentation and more build targets.<p>urs truly,<p>@ ᴗ @

AI Score Reasoning

This is a creative open-source developer tool with a clever technical stack, but it lacks the market size and commercial signals necessary for venture investment. It currently presents as a solo hobbyist project ('slinging pizza') rather than a scalable business entity.
