print-str, print-i64, print-f64, print-bytes, print-line and newline leave the prelude. print and println are the whole printing surface now, and print is the better call at every one of the sites that used them: it is the same structural walk without the newline, so the no-newline case the family was kept for is covered, and it takes the value as it is. The old print-i64 forced an explicit (i64 x) at every call site, because this language widens nothing implicitly; that cast is gone from 127 places. Dropping it moves one answer. hash-grid returns u64, and the cast through the signed printer showed sand-headless's hash as -2851001042534928384. print routes a u64 through flan_u64_to_bytes, so it now prints 15595743031174623232 — the same 64 bits, read as the unsigned number they are. The pinned expectation follows the correction. test-flan-dev.el and test_session.ml both reached for print-line as "a name the prelude has"; they reach for rand-seed instead.

;;;; The agent, end to end: a running program takes a redefinition over a

;;;; socket and installs it between "frames".
|
|
;;;;
|
|
;;;; [tick] is the function that gets redefined. It is called once before any
|
|
;;;; reload and once after each of two of them, and nothing else in this file
|
|
;;;; changes, so the three numbers are the whole result. Two reloads and not
|
|
;;;; one because that is the daemon's actual loop: a second module built from
|
|
;;;; the same session, reading state the first one introduced.
|
|
;;;;
|
|
;;;; It waits rather than polling on a timer because a test that races the
|
|
;;;; frame rate is a test that fails on a loaded machine. A game loop calls
|
|
;;;; poll at the top of the frame and ignores the answer; the split is in
|
|
;;;; vendor/agent/agent.flan.
