The trio the author decided on 2026-09-20 is now all built: def is CL's defparameter — its initialiser runs on every daemon re-run, unguarded, so an edited initialiser repaints the same storage on C-c C-c plus re-run — defonce (Clojure's name for CL's defvar, per the author) initialises once behind the .init~once. flag, and defconst stays the image. One parse arm reads both forms; the difference is Ast.reinit, carried to Tast.global's grerun. Emit.startup_plan gives a def no guard flag, and Check.check_global lifts every def initialiser — zero and literal included — into global/<n>, so the host's startup reaches it through the function cell and a re-evaluated def swaps it (Session's def_inits; Emit.redefinition declares the cell for a non-sibling target). The old defvar spelling is refused with the rename and both compiling spellings, and every program, test, doc and editor list is swept — except sand.flan, the author's live WIP, whose seven defvar lines are flagged in FIX.org and keep its three dependent tests red on this branch.

;;;; The zero-argument (agent/start): a program that names no socket at all.
|
|
;;;;
|
|
;;;; Under [flan dev] it binds where the daemon said, exactly as the explicit
|
|
;;;; form did, and nothing here can tell the difference. Run on its own — which
|
|
;;;; is what test_agent.ml does with it — it picks a path under /tmp and prints
|
|
;;;; it to stderr, and that printed line is the only way anything could connect.
|
|
;;;;
|
|
;;;; The second start is here to be a no-op. It answers 0 like the first, does
|
|
;;;; not bind a second socket, and does not print a second line; a program that
|
|
;;;; got its listener from somewhere else and also asks for one by hand is the
|
|
;;;; case that has to keep working.
