Glimmer Calculator v1.1.3 (Glimmer DSL for SWT desktop app) finally runs in Glimmer DSL for Opal on the web without needing to change a single line of Glimmer desktop GUI code. It is completely written in Ruby! This is the future of web development as we know it! You simply build apps for the desktop and they just work on the web. After all, web browsers are a desktop app and GUI is just GUI whether on the web or desktop. https://andymaleh.blogspot.com/2020/10/glimmer-calculator-v113-runs-on-glimmer.html
