Give every exported function a declaration, and check that it stays that way
Closes internal-consistency items 7 through 15. Nineteen non-static functions
were in the ABI with no declaration anywhere, so no consumer could call them
and any consumer could collide with them.
The four gamepad_handle_* functions are the ones that mattered: controller.h
declared akgl_controller_handle_button_down and three siblings that did not
exist, so anything compiled against the header alone failed to link. The
definitions carry the declared names now, which also closes Defects -> Known
and still open item 10, and their documentation moved to the header.
The rest are either declared under a "part of the internal API" block --
akgl_game_save_actors and akgl_game_load_versioncmp, which tests/game.c had to
declare for itself, plus six tilemap loader helpers the untested-loader work
wants to reach -- or static, which is what the four save iterators and
load_objectnamemap should always have been. akgl_path_relative_from is deleted:
declared nowhere, called from nowhere, never wrote its output, and leaked a
pooled string on every call, so it closes Known and still open item 4 and item
40 by ceasing to exist.
scripts/check_api_surface.sh keeps it closed. It reads the built library's
dynamic symbol table and every public header with comments stripped, and fails
on an exported akgl_* symbol that is declared nowhere. Stripping comments is
the whole point -- four of these were mentioned in controller.h prose, which is
how they went unnoticed.
The pool-size ceilings are defined once, in heap.h, so the #ifndef override
hook fires for the first time; actor.h, sprite.h and character.h were defining
the same four unconditionally from headers heap.h includes above its own guard.
tests/header_pool_override.c fails the compile if that regresses.
Also here: (void) rather than () on the twelve no-argument entry points,
AKERR_NOIGNORE only on declarations, static helpers with the akgl_ prefix
dropped, and the six parameter-name mismatches. akgl_get_json_with_default had
its two contexts swapped rather than merely misspelled -- the incoming one was
`err` and its own was `e`, which is the name reserved for an incoming one.

Stop returning past CLEANUP, and validate the arguments every sibling validates
Closes internal-consistency items 16 and 17.
Ten *_RETURN macros sat inside ATTEMPT blocks, which return past CLEANUP and
skip every release in it. The one that mattered was the success path of
akgl_get_json_tilemap_property: it leaked two of the string pool's 256 entries
on every lookup that *found* what it was asked for, and a map load does that
several times per layer. tests/tilemap.c now runs each of its three paths --
found, absent, wrong type -- twice the pool size and asserts the pool is where
it started. Against the old code that test does not merely fail, it segfaults,
which is Defects item 30 seen from the outside: pool exhaustion arriving as a
NULL strncpy rather than as AKGL_ERR_HEAP.
Two of the conversions needed more than swapping the macro. In
akgl_get_json_tilemap_property a plain break would have fallen through to the
"property not found" FAIL_RETURN after FINISH, reporting a miss for something
found, so the success path sets a flag. In akgl_collide_rectangles the eight
early exits are followed by `*collide = false;`, which would have overwritten
the hit that broke out; each corner test writes the flag itself, so that line
is gone rather than moved. The same function also released its scratch string
once per loop iteration while continuing to use it, so the slot was free while
still live -- one claim now covers the whole scan.
akgl_controller_default is the other behavioural one: its SUCCEED_RETURN was
the last statement in the ATTEMPT block, so the path that falls out of FINISH
reached the closing brace of a non-void function.
scripts/check_error_protocol.py keeps both rules enforced -- a *_RETURN inside
ATTEMPT, and a return out of a HANDLE block -- as the error_protocol test.
Neither produces a compiler diagnostic and neither fails a test run until the
pool it drains is empty, which is why both have already shipped once.
For item 17: the eight typed JSON accessors that validated their container and
then wrote through dest unconditionally now check key and dest as the two
string accessors always did; the null physics backend checks its actors like
the arcade one; and akgl_render_2d_frame_start, _frame_end and _shutdown check
self, which the first two read straight through. tests/renderer.c calls all
three with NULL, which segfaulted before.
25/25 pass, memcheck clean, reindent --check clean.

Reindent all C sources to the canonical stroustrup style
Mechanical whitespace-only change across src/, include/, tests/, and
util/, applied with scripts/reindent.sh. No behavioral change.
Most files already conformed. The genuine outliers indented at 2 columns
(json_helpers.c, util.c from akgl_rectangle_points onward, assets.c,
staticstring.c, akgl_actor_add_child, util.h, staticstring.h) or used
spaces where the canonical form is a tab (draw.c). cc-mode also re-aligns
line-continuation backslashes in multi-line macros to its default
c-backslash-column, which is required for the tree to be a fixed point of
the indenter.
Verified whitespace-only: `git diff -w` over this change is empty apart
from three trailing blank lines removed at EOF in src/heap.c,
src/registry.c, and tests/tilemap.c. The build produces no new errors and
ctest is unchanged at 13/14, with `character` still the one intentional
failure.
The tree is now a fixed point of `scripts/reindent.sh --check`.

Give every exported function a declaration, and check that it stays that way
Closes internal-consistency items 7 through 15. Nineteen non-static functions
were in the ABI with no declaration anywhere, so no consumer could call them
and any consumer could collide with them.
The four gamepad_handle_* functions are the ones that mattered: controller.h
declared akgl_controller_handle_button_down and three siblings that did not
exist, so anything compiled against the header alone failed to link. The
definitions carry the declared names now, which also closes Defects -> Known
and still open item 10, and their documentation moved to the header.
The rest are either declared under a "part of the internal API" block --
akgl_game_save_actors and akgl_game_load_versioncmp, which tests/game.c had to
declare for itself, plus six tilemap loader helpers the untested-loader work
wants to reach -- or static, which is what the four save iterators and
load_objectnamemap should always have been. akgl_path_relative_from is deleted:
declared nowhere, called from nowhere, never wrote its output, and leaked a
pooled string on every call, so it closes Known and still open item 4 and item
40 by ceasing to exist.
scripts/check_api_surface.sh keeps it closed. It reads the built library's
dynamic symbol table and every public header with comments stripped, and fails
on an exported akgl_* symbol that is declared nowhere. Stripping comments is
the whole point -- four of these were mentioned in controller.h prose, which is
how they went unnoticed.
The pool-size ceilings are defined once, in heap.h, so the #ifndef override
hook fires for the first time; actor.h, sprite.h and character.h were defining
the same four unconditionally from headers heap.h includes above its own guard.
tests/header_pool_override.c fails the compile if that regresses.
Also here: (void) rather than () on the twelve no-argument entry points,
AKERR_NOIGNORE only on declarations, static helpers with the akgl_ prefix
dropped, and the six parameter-name mismatches. akgl_get_json_with_default had
its two contexts swapped rather than merely misspelled -- the incoming one was
`err` and its own was `e`, which is the name reserved for an incoming one.
24/24 pass, reindent --check clean.

Stop returning past CLEANUP, and validate the arguments every sibling validates
Closes internal-consistency items 16 and 17.
Ten *_RETURN macros sat inside ATTEMPT blocks, which return past CLEANUP and
skip every release in it. The one that mattered was the success path of
akgl_get_json_tilemap_property: it leaked two of the string pool's 256 entries
on every lookup that *found* what it was asked for, and a map load does that
several times per layer. tests/tilemap.c now runs each of its three paths --
found, absent, wrong type -- twice the pool size and asserts the pool is where
it started. Against the old code that test does not merely fail, it segfaults,
which is Defects item 30 seen from the outside: pool exhaustion arriving as a
NULL strncpy rather than as AKGL_ERR_HEAP.
Two of the conversions needed more than swapping the macro. In
akgl_get_json_tilemap_property a plain break would have fallen through to the
"property not found" FAIL_RETURN after FINISH, reporting a miss for something
found, so the success path sets a flag. In akgl_collide_rectangles the eight
early exits are followed by `*collide = false;`, which would have overwritten
the hit that broke out; each corner test writes the flag itself, so that line
is gone rather than moved. The same function also released its scratch string
once per loop iteration while continuing to use it, so the slot was free while
still live -- one claim now covers the whole scan.
akgl_controller_default is the other behavioural one: its SUCCEED_RETURN was
the last statement in the ATTEMPT block, so the path that falls out of FINISH
reached the closing brace of a non-void function.
scripts/check_error_protocol.py keeps both rules enforced -- a *_RETURN inside
ATTEMPT, and a return out of a HANDLE block -- as the error_protocol test.
Neither produces a compiler diagnostic and neither fails a test run until the
pool it drains is empty, which is why both have already shipped once.
For item 17: the eight typed JSON accessors that validated their container and
then wrote through dest unconditionally now check key and dest as the two
string accessors always did; the null physics backend checks its actors like
the arcade one; and akgl_render_2d_frame_start, _frame_end and _shutdown check
self, which the first two read straight through. tests/renderer.c calls all
three with NULL, which segfaulted before.
25/25 pass, memcheck clean, reindent --check clean.

Reindent all C sources to the canonical stroustrup style
Mechanical whitespace-only change across src/, include/, tests/, and

Most files already conformed. The genuine outliers indented at 2 columns

Verified whitespace-only: `git diff -w` over this change is empty apart
from three trailing blank lines removed at EOF in src/heap.c,
src/registry.c, and tests/tilemap.c. The build produces no new errors and
ctest is unchanged at 13/14, with `character` still the one intentional

Add physics, heap, json_helpers, game, and actor test suites
Raise line coverage from 39.6 to 61.8 percent with four new suites and an
extension to the actor suite, and register every suite through a single
CMake list so a new test file cannot be left out of the coverage fixture.
Give the test targets a build-tree RPATH and prepend the build tree to
LD_LIBRARY_PATH for CTest, so a developer with a previously installed
libakgl.so exercises the library that was just compiled.
Fix six defects the new tests exposed:
- akgl_physics_simulate read self->gravity_time before its NULL check, so a
NULL backend crashed instead of reporting AKERR_NULLPOINTER.
- akgl_game_save transposed CLEANUP and PROCESS, which placed the fclose
inside the PROCESS switch. An ordinary save never flushed or closed its
stream and produced an empty file.
- akgl_game_save_actors wrote each name table terminator from the address of
a single char, emitting stack contents into the save file and a sentinel
the loader could not recognize.
- akgl_game_load_objectnamemap used CATCH directly inside while(1), where the
break leaves the loop rather than propagating, so a truncated name table
loaded as a successful game.
- akgl_Actor_cmhf_up_on and _down_on dereferenced actor->basechar with no
NULL check, unlike their left and right counterparts.
- akgl_actor_logic_movement checked actor twice instead of checking
actor->basechar before dereferencing it.

Namespace every exported symbol, and bump to 0.5.0
Closes internal-consistency items 1 through 6, 12 and 13. Every include guard
is _AKGL_<FILE>_H_, every in-project header include is angled, and every
exported function, type and global carries the akgl_ prefix. This is an ABI
break; the soname goes to libakgl.so.0.5. TODO.md carries the full rename
table.
The renames were driven by renaming each declaration and letting the compiler
find the uses, not by pattern substitution: renderer, physics and camera are
also parameter and struct-member names, and a sed would have rewritten
map->physics and every akgl_RenderBackend *renderer parameter without a word.
Item 4 turned out not to be cosmetic. The library exported a global called
renderer and tests/character.c defined an SDL_Renderer *renderer of its own;
the executable's definition preempted the library's, akgl_sprite_load_json
read a SDL_Renderer * through an akgl_RenderBackend *, and every texture load
in that suite failed. The suite reported success anyway, because libakerror's
unhandled-error handler ends in exit(errctx->status), exit keeps only the low
byte, and AKGL_ERR_SDL is exactly 256. So character had been green while
running one of its four tests, and every suite in the tree was unable to fail
on the most common status in a library built on SDL.
Both are fixed. tests/testutil.h gains TEST_TRAP_UNHANDLED_ERRORS(), which
collapses any status a byte cannot carry onto 1, and every suite installs it.
character binds a real backend with akgl_render_2d_bind. Its fourth test then
runs for the first time and fails on a defect it has asserted all along, so
akgl_heap_release_character now walks state_sprites with
AKGL_ITERATOR_OP_RELEASE and destroys the property set before zeroing the slot
-- TODO.md Defects item 21 and half of Carried over item 1.
AKGL_TIME_ONESEC_MS said "one second in milliseconds" and held 1000000, so
akgl_game_state_lock waited roughly sixteen minutes rather than one second. It
is AKGL_TIME_ONEMS_NS now, the budget is its own named constant, and
tests/game.c holds the mutex from a second thread to assert the wait -- the
contended path had no coverage at all.
Headers are self-contained and it is enforced: AKGL_PUBLIC_HEADERS drives both
install() and a generated translation unit per header, so a header that ships
is a header that is checked. Writing that found registry.h, which used
SDL_PropertiesID in eight declarations and included no SDL header.
23/23 suites pass, memcheck is clean, reindent --check is clean.

Reindent all C sources to the canonical stroustrup style
Mechanical whitespace-only change across src/, include/, tests/, and
util/, applied with scripts/reindent.sh. No behavioral change.
Most files already conformed. The genuine outliers indented at 2 columns
(json_helpers.c, util.c from akgl_rectangle_points onward, assets.c,
staticstring.c, akgl_actor_add_child, util.h, staticstring.h) or used
spaces where the canonical form is a tab (draw.c). cc-mode also re-aligns
line-continuation backslashes in multi-line macros to its default
c-backslash-column, which is required for the tree to be a fixed point of
the indenter.
Verified whitespace-only: `git diff -w` over this change is empty apart
from three trailing blank lines removed at EOF in src/heap.c,
src/registry.c, and tests/tilemap.c. The build produces no new errors and
ctest is unchanged at 13/14, with `character` still the one intentional
failure.
The tree is now a fixed point of `scripts/reindent.sh --check`.
include/akgl/SDL_GameControllerDB.h is generated and excluded.

Give every exported function a declaration, and check that it stays that way
Closes internal-consistency items 7 through 15. Nineteen non-static functions
were in the ABI with no declaration anywhere, so no consumer could call them
and any consumer could collide with them.
The four gamepad_handle_* functions are the ones that mattered: controller.h
declared akgl_controller_handle_button_down and three siblings that did not
exist, so anything compiled against the header alone failed to link. The
definitions carry the declared names now, which also closes Defects -> Known
and still open item 10, and their documentation moved to the header.
The rest are either declared under a "part of the internal API" block --
akgl_game_save_actors and akgl_game_load_versioncmp, which tests/game.c had to
declare for itself, plus six tilemap loader helpers the untested-loader work
wants to reach -- or static, which is what the four save iterators and
load_objectnamemap should always have been. akgl_path_relative_from is deleted:
declared nowhere, called from nowhere, never wrote its output, and leaked a
pooled string on every call, so it closes Known and still open item 4 and item
40 by ceasing to exist.
scripts/check_api_surface.sh keeps it closed. It reads the built library's
dynamic symbol table and every public header with comments stripped, and fails
on an exported akgl_* symbol that is declared nowhere. Stripping comments is
the whole point -- four of these were mentioned in controller.h prose, which is
how they went unnoticed.
The pool-size ceilings are defined once, in heap.h, so the #ifndef override
hook fires for the first time; actor.h, sprite.h and character.h were defining
the same four unconditionally from headers heap.h includes above its own guard.
tests/header_pool_override.c fails the compile if that regresses.
Also here: (void) rather than () on the twelve no-argument entry points,
AKERR_NOIGNORE only on declarations, static helpers with the akgl_ prefix
dropped, and the six parameter-name mismatches. akgl_get_json_with_default had
its two contexts swapped rather than merely misspelled -- the incoming one was
`err` and its own was `e`, which is the name reserved for an incoming one.
24/24 pass, reindent --check clean.
