A simple ClojureScript environment integrates: self-rewriting plain text, live inspection, inline visualizations, distributed tracing, deployment, declarative process reconciliation, and object capability security.

Programmers assign functions to nodes. (“What should run where?”) A process is a function running on a node; it receives all platform capabilities as an argument. Each node reconciles its process state to match the latest specification. Top level forms set their liveness, and may evaluate across the system on every keypress. Stateful expressions preserve node-local values across code changes. The editor is also a node. Data passing through any expression, on any node, is observable as live text in the editor. Visualizations render inline with the code, through functions defined in the same code.

Examples range from structured personal notes through computational documents, up towards open-world integration with hardware, filesystems, servers, browsers, and third-party dependencies to build, run, inspect, and change small distributed systems from within a lightly enhanced text editor.
