The INSERTIONSORT crash, all three rulings (FIX.org 2026-09-20):
- (bytes s) allocates a writable copy through the allocator surface —
context or (bytes s a), StorageExhausted with retry, a registry note in
dev builds (flan_bytes_dup, lowered like vec-new). (bytes-view s) is the
old zero-cost reinterpret, renamed, read-only by convention; every
in-repo reader swept over to it. (string b) unchanged.
- String constants were already read-only on both backends at -O0; now
pinned — bytes-copy.flan rows on LLVM/-O0/--x86, and dies_segv rows
asserting the write-through-view trap on both backends.
- A dev build installs a SIGSEGV/SIGBUS handler by the same dev-only
constructor slot that arms the registry: one line naming the address and
the innermost frame, then the trap-hook park — stopped, not dead, the
daemon serving. No agent: message and re-raise. Release builds untouched.
Pinned by trap_park over dev-segv.flan.
Key members are :key-r, :key-space, :key-left-shift; MouseButton members
are :mouse-left through :mouse-back — mouse- over button- because gamepads
have buttons too. Bare members collided across enums and with user code.
The bindings enum directive grew an optional third column declaring the
Flan-side member prefix, stripped before the C prefix is applied, so key-r
checks against KEY_R rather than KEY_KEY_R; a member that does not carry
the declared prefix is reported, not checked under a guessed name. The
enum-member error grew a did-you-mean: one edit away, or the bare name of
a prefixed member, so :r suggests :key-r.
sand.flan is the author's live WIP and is deliberately not touched; its
three keywords (lines 161-166) leave test_session and sand-headless red
until he moves them. Everything else that calls the two enums moved.
vendor/raylib/modes.flan: five macros over the five pairs the package binds
-- with-drawing, with-mode-2d, with-mode-3d, with-texture-mode,
with-scissor-mode. A second file with no declare-c in it, split out on
vector.flan's reasoning: raylib.flan is the package's statement about C and
nothing here names C, so nothing here can be made wrong by raylib changing.
Each expands to (do (begin-... args) body... (end-...)) -- the calls the
author used to type, in the order they typed them. No let, no gensym: nothing
binds a name, so there is nothing for a caller's name to collide with.
What it removes is the End* that is missing, wrong, or no longer beside its
Begin*. What it cannot remove is a body leaving through the unwind path: a
return or an invoke-restart skips the rest of the do and the End* with it.
defer is the obvious fix and is refused inside a loop body, which is where a
pair always lives -- checked, not assumed. So sand.flan's discipline stays:
keep the restart boundary outside the pair.
35 call sites converted across examples/ and sand.flan. The one left is
core-scissor-test.flan, whose Begin and End sit in two separate `when`s with
the drawing between them -- a conditional pair is a shape a bracketing macro
cannot express.
test/programs/rl-with.flan covers with-scissor-mode, which no example can,
with a frame function unreachable from main so it needs no libraylib;
rl-with-reject.flan is the arity half.
Three shapes, two text, three textures, one models and one core, picked for
binding surface rather than for how they look.
shapes-basic-shapes brings in six draw families nothing had called — the
circle and rectangle gradients, the triangles, all three poly draws — and is
the first call in the corpus to pass two Colors or three Vector2s at once.
shapes-collision-area is get-collision-rec, the only binding that takes two
Rectangles and answers a third, on a frame path. shapes-following-eyes is the
raymath gap measured rather than worked around: every line of it is vector
arithmetic written without a vector library, the way the C writes it.
text-input-box drains get-char-pressed's queue, which no example had read,
and needed a MouseCursor defenum for set-mouse-cursor. text-writing-anim
replaces TextSubtext — unbindable, it answers a pointer into a rotating
static buffer — with (string (slice b 0 n)), which is the same operation
without the shared state.
textures-image-generation runs nine Gen* calls and the
gen/upload/unload-image path, all procedural, no file on disk.
textures-fog-of-war needed a TextureFilter defenum: the smooth fog edge is
entirely :bilinear on a 25x15 render texture, and it is also the first
draw-texture-pro with a negative source height. textures-mouse-painting is
the same render texture used as a document rather than as scratch, plus the
round trip back off the GPU — load-image-from-texture, image-flip-vertical,
export-image — which nothing had run.
models-box-collisions is the counterexample to "a models example is a binding
exercise": nothing in it is a Model, and one BoundingBox defstruct un-refuses
four functions. core-3d-picking is the only caller anywhere for Ray and
RayCollision, and picking is the inverse of the get-world-to-screen the
corpus already had.
Added to vendor/raylib: defstructs BoundingBox, Ray and RayCollision;
defenums MouseCursor and TextureFilter with their mapping lines in bindings;
hand-written declare-c for SetMouseCursor, SetTextureFilter, DrawCubeV,
DrawSphere, DrawSphereWires, DrawRay and GetScreenToWorldRay, each excluded
from the generated half on the rule bindings already states. generated.flan
regenerated against raylib 5.5: 272 declarations, 117 refused, every
defstruct, hand-written declare-c and mapped constant agreeing with the
header.
