Calva https://github.com/BetterThanTomorrow/calva/releases/tag/v2.0.293 is out. It makes me happy to see three new code contributors in the latest few releases. Warms thanks to @ajoberstar @maksimrv @am ❤️ 🙏. As warms thanks to the usual suspects too! Main news since last announced, Calva now: • has improved clojure-lsp integration • has an experimental first version of Clojure Notebooks (my crystal ball for this reveals the blurring of regular REPL driven development and Notebook workflows) • offers customizable inline result styling • defaults to inject fresh versions of nREPL and related tools • contains fewer bugs (haha, well, I actually think that recently we have fixed more than we have added)

An initial release of https://github.com/amperity/separator is hot off the presses! This is an open-sourced version of Amperity's internal CSV parsing library, which we developed in response to the truly wild variety of delimiter-separated value data we were getting from our clients. Separator's primary purpose is customizable and defensive parsing, allowing it to handle many kinds of messy data files without exploding. With that, it's still significantly faster and more efficient than clojure.data.csv, but not quite as fast as Jackson. It also includes writing capability, making it a general-purpose DSV codec.

Introducing ClavaScript, a ClojureScript syntax to JavaScript compiler! The primary use case for clava (its short name, not to be confused with Calva) is to produce JavaScript using ClojureScript syntax while producing ultra-small bundle sizes, by leveraging the JS platform directly. Clava does not protect you from the pitfalls of JS (mutability, equality), but lets you use the concepts you already know from ClojureScript and maps them more or less directly to JS where this makes sense. It comes with a standard library which has many of the core functions you know: map-indexed , for example, works like you would expect, but returns a mutable JS array instead of an immutable vector. Repo: https://github.com/clavascript/clavascript Npm: npm install clavascript Read https://github.com/clavascript/clavascript#differences-with-clojurescript for... well, the differences with ClojureScript. It has support for https://github.com/clavascript/clavascript#asyncawait and https://github.com/clavascript/clavascript#jsx. Clava is open to contribution, especially in the area of porting core functions. An example of a SolidJS app written using Clava: https://clavascript.github.io/demos/clava/solidjs/ (https://github.com/clavascript/clavascript/blob/main/examples/solidjs/src/App.cljs) Give it a spin and let us know what you think in #clavascript On behalf of the Clava core team (@borkdude, @lilactown, @corasaurus-hex): enjoy!

Fulcro 3.5.24 release to Clojars. The new version supports composing a transaction during routing that can run in pessimistic mode so that the parent’s ops complete before children. See https://book.fulcrologic.com/#_path_ordered_pessimistic_transactions_requires_fulcro_3_5_24
