@page runs web/examples/check.sh and web/examples/quotes.sh against the compiler
dune just built. @cells runs spike/x86/cells.sh, which was a real pass/fail check
-- four builds, two backends, 22 22 against 42 42 -- that nothing in the tree ran.
@checks is @page, @x86 and @cells together, and its comment argues for where the
boundary sits: everything you can run while making coffee is in, @sanitize and
@valgrind are out because folding tens of minutes in would make the umbrella the
thing nobody has time for, which is the disease rather than the cure.
All three scripts learned to resolve FLAN to an absolute path, which is what
actually stood between them and a dune rule: %{workspace_root} expands relative to
the directory the rule is written in, and every one of these scripts cd's somewhere
before using it. The first run of @page failed with twenty diffs all saying
'../bin/main.exe: No such file or directory', which is at least a failure that says
what is wrong.
docs/BUILT.md carried the same colon-spelled renderer block index.html did, from the
same sweep. Nothing checks BUILT.md, so it is corrected here by hand.
The renderer check greps a line out of NEXT.md, and NEXT.md is a scratch document
that gets rewritten. The line went, the grep went empty, and the empty-needle guard
did its job and said so -- into a report nobody was reading. Behind that noise the
page was genuinely wrong: the colon-to-dot sweep rewrote every field label in the
corpus and lib/render.ml writes .field today, so the inspector block on the page had
been showing {:x 1.5 :y 0} for a renderer that prints {.x 1.5 .y 0}. test_repl.ml's
fixtures are the authority and they are dots throughout, with an enum member still a
colon; the page now matches. The anchor moves to test/programs/raylib-imported.flan,
which dune test builds and runs, so it cannot quietly stop saying it.
The LLVM excerpt beside it moved too: a --dev main pushes a condition frame before
anything else now, which shifted the SSA numbering by one. The three quoted lines are
what flan emit --dev prints today, with the frame push marked as elided rather than
silently dropped.
quotes.sh had been red since the compiler's diagnostics grew a source excerpt: the
needle swallowed the caret lines, so result, quoted and i64index failed against a
page that is in fact correct. It now compares the message and nothing else.
Six other probes are deleted rather than fixed. Vec, Map, Handle, an Fn-typed
parameter, a defer inside a let and break were all refused as not-implemented when
the loop was written; all six work today and the page's table lost their rows as
each landed, so the probes were the last thing in the tree asserting a claim the
page no longer makes. What made this invisible for weeks is worth recording: flan
check answers a program that compiles with its whole symbol table, so each of those
probes failed by printing eighty lines of prelude signatures. A clean exit is now
its own one-line failure saying the page's claim has gone stale.
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.
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.
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.
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 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.
