print and println had no line anywhere on index.html — a builtin the reader
meets in the first example and is never told about. There is a section for
them now, between arrays and the prelude: what the walk covers, that an enum
comes back as its name and a Ptr does not get followed, that a string is raw
at the top and quoted inside a structure, and that the depth and span caps
are what keep a grid from printing a screenful. printing.flan is beside the
other examples so check.sh has been green on every line of it.
The prelude's table loses its output row, because the prelude has no output
functions left, and the fifty-odd example blocks follow the files they quote.
Two pinned things moved. sand-headless prints 15595743031174623232 where it
printed -2851001042534928384: same bits, read unsigned, because the cast that
made it signed is gone. bounds.flan's trap moved from column 28 to 19, which
is where (at xs i) now starts on that line.
And the indirection-cell illustration is defer.flan rather than hello.flan.
hello.flan cannot show a cell any more: its one call was to a prelude
function, and println is compiler-provided, so the smallest program makes no
Flan-to-Flan call at all. defer.flan's main calls work, and is already on the
page a few sections up.
nth and at were documented as the same operation, and as reads they were:
check.ml matched "at" | "nth" in one arm. But a place is recovered in two
other spots -- parse.ml for (set ...) and place_of_expr for (addr ...) --
and both match only Sym "at". So (set (nth a i) x) and (addr (nth a i))
were refused while the at forms worked.
Two names said to be identical that disagree about writing is worse than
one name, and the asymmetry is not worth fixing in three places to keep a
synonym. at is the indexing operation; nth is gone.
The six call sites were all reads, so they rewrite directly. get/put stay
the Map pair: get returns (Option V) and is deliberately not a place.
nth-gone.flan pins the removal -- it has to fail as a name nobody defined,
not quietly resolve to at again.
destructure~nth is compiler-generated and unrelated.
The prose lane branched before the CIDER buffers landed, so the page still
described C-c C-b as the minibuffer prompt. It is the conditions buffer now, the
prompt moved to C-c C-M-b, and C-c C-i, C-c C-a and C-c C-g are missing
entirely.
Checked against the real keymap rather than against the source: loading
flan-mode in a batch Emacs and asking key-binding what each one resolves to.
That is what caught C-c C-g being unbound - flan-dape.el registers it from its
own file so that flan-mode still works without dape installed - so the row says
so rather than claiming a binding that is not there.
Forty-odd clauses of the shape "— which is what makes X work" and "that is the
point of Y". Each one restates in the abstract what the sentence before it had
just said concretely, and a reader who followed the first does not need the
second. The facts are unchanged; the examples are untouched.
Nineteen entries at the top of a long page are scrolled past once and then
unreachable. A fixed column stays put and scrolls on its own. Below 66rem there
is not room for two columns, so it collapses to a bar with a toggle — a
checkbox, so the page still needs no script to navigate.
The wordmark's dot was a circle at a guessed x, which drifted from the n
whenever the reader's serif was not the one it was measured against. It is a
full stop in the same text run now.
The quote checker found three of them on the first run against the new tip: the
sand hash was changed deliberately by the grid lane, break and continue now
refuse by name instead of reading as unknown functions, and the usage text grew
--debug. The prelude also grew a string and UTF-8 family the table did not list.
`case $x in *""*)` is always true, so every check whose text came from a grep
went green the moment the line it greps for was renamed — which is exactly the
case those checks exist for, and they guard files other lanes are editing.
Verified by pointing one grep at a string that is not there: ok before, FAIL
after. sqrt-f32 was overstated in the same spirit; it is a declare, not Flan.
"Every program below was run" is the kind of assurance nobody can act on. Naming
check.sh and quotes.sh turns it into something a reader can re-run, and says
plainly that a disagreement makes one of them go red.
It is the project's headline cross-target claim and the page was asserting it
second-hand. Both targets print 2256461126764447066 on this machine, so the
transcript is now what the page shows.
plan.org settled the loop story as "while/for with break/continue and return",
so a reader will reach for them; they are not implemented and, unlike the rest,
not refused by name either — they come back as unknown function.
The paraphrase of why a wide index is refused was shorter and said less than
the message; and the keybinding table came from NEXT.md, which is two keys
behind flan-mode.el, so it now reads the keymap instead.
The rule was "capitalised is a type", which leaves i32 and string looking like
ordinary names in the one position — a signature — where the reader is there
to see the types.
The blocks that are not programs were the ones that had drifted: the usage text
had lost its indentation and the refusal table had trimmed "(see plan.org)" off
every message, so the page was showing wording the compiler does not print.
Everything here is checked against the compiler rather than against plan.org:
the design documents describe a language larger than the one that runs, and a
page that documented the plan would mislead the first person to try it.
