A completed sampling: the points, and the text they came from.
A completed sampling: the points, and the text they came from.
The two strings are carried because a plot has to say what it is showing — they title the axes — and the alternative was for the caller to split the command a second time to recover them. A second parse of the same text is exactly the sort of duplicate this codebase removes on sight: the two could disagree, and then a figure would be labelled with something other than what it plots.
Value parameters

A completed frequency sweep: (omega, magnitude-in-dB, unwrapped-phase-in-degrees).
A completed frequency sweep: (omega, magnitude-in-dB, unwrapped-phase-in-degrees).
Distinct from Samples because a Bode diagram is two curves over one shared frequency axis, not one curve; flattening it to pairs would lose the pairing that makes the two panels line up.
Value parameters
- expr
-
the plant as the user typed it
- points
-
the swept response, ascending in omega
- variable
-

Returns the help text for a specific topic, or the full help listing when not found.
Returns the help text for a specific topic, or the full help listing when not found.
Value parameters
- topic

the command token to look up (e.g.
"simplify",":=")

Reads a saved session and replays it. Backs :load.
Reads a saved session and replays it. Backs :load.
The storage medium is platform-specific; this dispatch is not (issue F_0003 phase 2). SessionIO is a file path on the JVM and a localStorage key in the browser, so :load work means the same thing in both and only the medium differs. What made that cheap is that Session.load was already pure string-in: the file system was the only JVM-bound part of the command, and it was never inside Session.
Value parameters
- path
-
the session name — a file path on the JVM, a storage key in a browser
- session
-
the session to replay the script into
Attributes
- Returns
-
the script's own output, or a message explaining why it could not be read
Writes the session's replayable script. Backs :save; see loadFile on storage.
Writes the session's replayable script. Backs :save; see loadFile on storage.
Value parameters
- path
-
the session name — a file path on the JVM, a storage key in a browser
- session
-
the session to serialise
Attributes
- Returns
-
a confirmation, or a message explaining why it could not be written
Interprets one line read by the REPL loop, resolving the commands execute cannot: the file-IO :load/:save and the quit/exit sentinels. A None line stands for end-of-input (Ctrl-D). Returns None to stop the loop, or Some(output) to continue — output is the (possibly empty) text to print. This keeps the loop's dispatch logic unit-testable; only the JLine plumbing in repl() is interactive-only.

Points taken by samples / Session.samplePoints when the count is omitted.
Named rather than inlined because it is now read by two renderings of one sampling — the printed table and the browser's plot — and a plot drawn at a different default density from the table beside it would be quietly confusing.
