(request :id <abort-id> :op abort :target-id <eval-request-id>)

The abort responder gets :status ok :aborted <eval-request-id>; the interrupted eval receives :status error :code "interrupted"; the session survives and evaluates normally afterward. (A single top-level form that mixes a top-level define with a long loop runs on the immediate, non-abortable path — define at top level, then run, as separate requests.)

Output streaming

Output written during an eval is streamed back incrementally as it happens, before the final response, carrying the original eval request id:

(response :id <eval-id> :status out :out <string>)   ; stdout
(response :id <eval-id> :status err :err <string>)   ; stderr

followed by the normal terminal (response :id <eval-id> :status ok :value …). The bundled (sigil nrepl client) transparently drains these frames and returns the terminal response from nrepl-eval.

Embedding an nREPL server

(import (sigil nrepl))

(define server (nrepl-start port: 7888))

;; In your app's main loop, drain pending requests:
(nrepl-process-pending server)

;; On shutdown:
(nrepl-stop server)

Connecting from a client

(import (sigil nrepl client))

(define conn (nrepl-connect "127.0.0.1" 7888))
(nrepl-eval conn "(+ 1 2)")        ; => ((status . ok) (value . "3"))
(nrepl-switch-module conn "(my app)")
(nrepl-disconnect conn)
