ethers gem - Rails-Like All-In-One Umbrella For Ethereum & Co.
Hello, to make it easier to get started with blockchain (contract) programming in ruby - and inspired by the rails gem - I put together the ethers gem - a âhigh-levelâ all-in-one umbrella quick starter gem for easy installation & usage for ethereum & co. (blockchain) contract services that for now bundles crypto-lite, etherlite, etherlite-contracts, ethname, etherscan-lite, abidoc, abigen, & some more gems. The ethers name is inspired by ethers.js (or ethers.rs) and letâs you use ârequire âethersâ in rubyland or âgem install ethersâ to get started. Anyways, itâs the early days in crypto winter 2022/23. Happy blockchain (contract) programming with ruby. Questions and comments welcome. Cheers. Prost.
abigen gem - Application Binary Interface (ABI) Contract Generator for Ruby
Hello, in the ongoing crypto winter ethereum & co. programming series I put together some more gems. The new abigen gem lets you generate ready-to-use (blockchain) contract services / function calls for ethereum & co. via application binary inferfaces (abis). Bonus: Via the new natspec gem you can even âauto-includeâ nat(ural) spec(ification) comments / documentation in the generated ruby code. See the pre-packaged auto-generated ruby classes in the ethlite-contracts gem, for some first real-world samples.

Glimmer DSL for LibUI Table Lazy Loading
Glimmer DSL for LibUI 0.6.1 has been released with support for table lazy loading via Enumerator (or Enumerator::Lazy). As a result, the table control can now handle millions of rows and renders instantly without waiting for all data to be loaded given that it is loaded lazily as the user scrolls through the table. That enables applications with a lot of data to start instantly. A new example, Lazy Table, has been included to demonstrate table lazy loading. https://andymaleh.blogspot.com/2023/01/glimmer-dsl-for-libui-table-lazy-loading.html

Using Nebula TextAssist from Glimmer DSL for SWT
Recently, I received a support request concerning Glimmer DSL for SWT (JRuby Desktop Development GUI Framework) and the use of Nebula Custom Widgets, specifically the text_assist widget (auto-complete text field). For a quick background about Nebula, it is a collection of 55+ enterprise-grade high-quality SWT (Standard Widget Toolkit) custom widgets, including a progress circle, a password revealer, and an oscilloscope. Thanks to Glimmer DSL for SWT, they are usable from Ruby. https://andymaleh.blogspot.com/2023/01/using-nebula-textassist-from-glimmer.html
