Namespaces

Rayfall's builtins are organised under dotted namespaces. Names beginning with . are reserved — user code cannot shadow them with set or let (the only exception being the five .ipc.on.* hook slots). Each page below documents every builtin in that namespace: arity, restricted-mode flag, signature, semantics, and at least one worked example.

Reference

Namespace	Purpose
.col.*	Foreign-key style column-to-table linking and dotted dereference.
.csv.*	CSV import/export — in-memory, splayed-on-disk, and partitioned variants.
.db.*	On-disk table I/O: splayed and partitioned get / set / mount.
.graph.*	Graph builders and algorithms (PageRank, Louvain, Dijkstra, MST, BFS/DFS, expand, …).
.idx.*	Accelerator indexes: bloom, hash, sort, zone.
.ipc.*	TCP client IPC and the server connection-hook accessor.
.log.*	Write-ahead log: open, write, sync, snapshot, roll, replay, validate.
.os.*	Filesystem and environment: getenv, setenv, list, size.
.repl.*	Interactive REPL control — attach the local REPL to a remote server.
.sys.*	System info and shell-style commands: build, info, mem, gc, exec, listen, timeit, env, cmd.
.time.*	Monotonic clock and timer scheduler.

Restricted-mode summary

When the server is started with -U <password>, the following dotted builtins are blocked (return an access error) for IPC peers — see IPC restricted mode. Page-level admonitions on each namespace flag the exact builtins that carry the RAY_FN_RESTRICTED attribute.

• .csv.read, .csv.write, .csv.splayed, .csv.parted
• .db.splayed.set
• .ipc.open, .ipc.close, .ipc.send
• .log.open, .log.replay, .log.roll, .log.snapshot, .log.close
• .os.getenv, .os.setenv
• .repl.connect, .repl.disconnect
• .sys.exec, .sys.cmd, .sys.listen
• .time.timer.set, .time.timer.del

.col.*, .graph.*, .idx.*, and pure read/inspect builtins (.db.splayed.get, .db.parted.get, .os.size, .os.list, .log.write, .log.sync, .log.validate, .sys.build, .sys.info, .sys.mem, .sys.gc, .sys.env, .sys.timeit, .ipc.handle, .time.now) are always available.
