yuhan0 / datastar.expr.clj

Last active May 13, 2025 06:56

	(ns datastar.expr
	(:require [clojure.string :as str]
	[clojure.walk :as walk]))

	;; The motivation here is to provide a thin syntactic veneer over constructing strings
	;; representing Datastar expressions (basically JS snippets embedded in DOM attributes)
	;;
	;; Takes inspiration from Scriptjure, but targeted more specifically to the Datastar context,
	;; and does not aim to implement Clojure-like truthiness / value semantics (cf. Squint, Clojurescript)
	;; or to enable the writing of arbitrarily nested complex expressions (an antipattern)
