The first cut scanned the initialiser's tokens and required every one to be a
literal or an operator. That is exactly the kind of approximation this work has
been removing, and it was wrong in both directions:
const int A = sizeof(Big); missed — `sizeof` is a keyword
const int B = Base + 1; missed — `Base` is an identifier
const auto C = 5_notConstexpr; would have been reported, wrongly
clang_Cursor_Evaluate answers the question directly. Evaluating a variable
declaration evaluates its initialiser, so anything that folds is recognised and
a call result still is not. Costs nothing measurable — lint stays at ~15s.
Found one real case the token version could not see: an EShMessages fold over
three glslang enum constants in Crafter.Build-Shader.cpp. Promoting it to
constexpr then made `naming` ask for constant naming, since a constexpr
variable is a compile-time constant — so it is `Messages` now. Two rules
agreeing on the same declaration is the intended behaviour.

Two rules the AST makes possible, plus the mutation analysis behind them.
const-local reports a local that is never written. It is restricted to SCALARS
— integers, bools, enums, floating types — and that restriction is what makes
the answer exact rather than a guess: a scalar has no member functions, so the
only ways to write one are assignment, ++/--, having its address taken, or
binding to a non-const reference. All four are now tracked in the walk:
- assignment and compound assignment visit their LEFT operand in a write
context, the right one normally;
- ++/-- and & write their operand;
- a call argument is checked against the callee's parameter type, so passing
to `const int&` or by value is a read while `int&` is a write;
- initialising a non-const reference writes what it binds to.
For a class type a non-const method call could mutate it, and deciding that is
the whole-program analysis clang-tidy does, so those are simply out of scope
rather than guessed at.
constexpr-constant promotes a const constant whose initialiser is made only of
literals and operators, so `const int A = 1 << 4;` qualifies and
`const int B = Compute();` does not.
On this repository const-local found 103 candidates, which was too many to be
useful, and the reason was informative: most were range-for bindings and
pointer locals. `for (T* const x : …)` and `T* const p` are not spellings
anybody writes, and the useful constness for a pointer is on the pointee, which
this rule cannot advise on. Excluding both leaves 36, all plain bool or enum
locals worth fixing — isWasm, isPe, exists, writes, isC and so on. Those 36 are
fixed in this commit; the compiler verified every one.
Both rules are report-only. The analysis is exact, but adding const is a
judgement about intent as much as mechanics, and a wrong suggestion should cost
a glance rather than a build. const-local also deliberately does not become a
transform: inserting `const` before a shared type would apply it to every
declarator in a multi-declarator statement, including any that IS written.
Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
Tokens are not enough for this one, which is worth stating because it is the
opposite of the enum-class case. Splitting a multi-declarator statement by
copying the shared type prefix is wrong in C++:
int* a, b; -> int* a; int* b; // b was int, not int*
Only per-declarator types get it right, and clang has already resolved them —
`int *` for a, plain `int` for b. A token-based splitter cannot know.
The regex it replaces bailed on `*`, `&`, `<>`, parens and quotes, so pointers,
templates and call initialisers were all left alone. All three split now, and
the fixture proves the mixed pointer case above comes out correctly.
Groups are found structurally rather than by matching a line shape: the first
declarator's extent starts at the shared type, so begin < nameOffset, while a
continuation declarator's starts at its own name, so begin == nameOffset. That
signal comes from the AST itself. nameOffset is now on LintDecl, which is also
what lets the replacement reuse each declarator's original text verbatim
instead of reconstructing it.
Replacing a byte range rather than rewriting whole lines means a comment after
the ';' is outside the edit and survives — the line-based version refused to
touch any line carrying a comment. A comment INSIDE the statement still bails,
since the rewrite would swallow it.
Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
The rewrite itself stays token-shaped — it edits type SPELLINGS, which an AST
discards — but what it must not touch now comes from the AST.
The old exemption was per LINE: `int main`, `argc`, `argv`, `extern "`. Being a
transform, a missed exemption here does not over-report, it emits code that no
longer matches the API being called, so this is the rule where guessing from
substrings mattered most. And being per-line, it also disabled the rule for
anything sharing a line with one of those words.
Now a declaration with C language linkage, or one whose initialiser binds to an
entity declared outside the project, contributes a protected byte range and
keeps its spelling. That answers the case directly: a function declared in
somebody else's header taking `unsigned int` keeps `unsigned int`, and a local
initialised from strtoul keeps `unsigned long`, because of where those are
declared rather than because of what the line says.
main is protected from the start of its declaration to the opening brace of its
body, not for its whole extent. Its signature is fixed by the language; its body
is ordinary code. Three findings on this repository came out of that
distinction, all correct:
for (int i = 1; i < argc; ++i) -> for (std::int32_t i = 1; ...)
skipped before only because `argc` appeared on the line, plus Crafter::Run's own
`int argc` and return type, which are ours rather than the language's.
All three AST rules now share one interop test instead of carrying a denylist
each, and it is the same test: whose header dictates this spelling.
Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
The rule was `\bchar\s*\*` over the text minus a substring denylist — argv,
getenv, setenv, dlerror, c_str, .data(, reinterpret_cast, extern ". Every entry
was a patch for one interop site, the list could only grow as libraries
arrived, and each entry disabled the rule for the whole LINE it appeared on.
It now walks declarations and asks the question the denylist was approximating:
whose header dictates this spelling? A declaration with C language linkage, or
one whose initialiser binds to an entity declared outside the project root, is
somebody else's API and keeps its spelling. getenv, c_str and friends are
exempt because of where they are declared, not because they are named here, so
a new external library needs no new entry.
Two bugs found while testing this, both of which had made the rule silently
pass over the entire repository:
clang_getCursorLanguage cannot be used to detect extern "C". Its default answer
is CXLanguage_C for a plain function, variable or parameter even in a C++
translation unit, so isExternC was true almost everywhere and exempted
everything. Replaced by tracking CXCursor_LinkageSpec depth during the walk,
reading the extent text to tell extern "C" from extern "C++".
Attributing any foreign reference in a subtree to the enclosing declaration was
too broad: a function that merely touched libc++ somewhere in its body would
exempt its own signature. Narrowed to initialiser contexts — a variable, field
or parameter — which is where a binding to a foreign API actually occurs.
Also: functions now carry their RESULT type rather than the whole function
type, since the parameters arrive as their own declarations and would otherwise
be reported twice. main's parameters are exempt structurally, its signature
being fixed by the language rather than chosen here.
Two sites keep an explicit lint-disable, both Crafter::Run taking main's argv
verbatim. That is two visible, reasoned suppressions in place of a denylist
that silently disabled the rule for every line mentioning one of eight tokens.
ExternalCloneDir and ExternalIncludeFlags are now exposed from :External, so a
source that includes an external dependency's headers can be parsed without
running a build to discover where they are. BuildExternal derives its own
working directory through the same function, so the two cannot drift.
Crafter.Build-Shader.cpp needed this to parse at all.
A file with no compile command — project.cpp, which LoadProject builds with its
own flags — is not a translation unit of the build graph, so AST rules skip it
the way a rule self-filters by extension. That is distinct from a file that
should have parsed and did not, which stays an error.
Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
Adds LintContext::Decls() — clang's view of the declarations written in the
file — plus AddAstLintRule to register a rule that reads it. No rule uses it
yet; the three that will are migrated separately.
The declarations come back as a flat vector with parent indices rather than an
opaque cursor handle: no lifetimes cross the project-DLL boundary, no callback
hops back into project.so per node, and "is this at namespace scope or inside a
function?" becomes an index lookup instead of a hand-rolled brace stack.
Three things had to be solved for this to work at all on this codebase.
libclang cannot see through `export`. A C++20 export declaration has no
CXCursorKind, so `export namespace Crafter { … }` arrives as a childless
CXCursor_UnexposedDecl and clang_visitChildren does not descend. Five of the
eleven interfaces here are written that way — 677 lines, including
Configuration and LintContext, yielding zero usable cursors. A plain
`namespace` IS descended into, so the fix is to blank the keyword before
parsing, byte-length preserving so every line and column still lands on the
original file. `export module` is left alone or the unit stops being a module
interface. Verified end-to-end against a fixture whose asserted line numbers
match the unblanked file.
PCMs are flag-locked, so each file has to parse with the flags that built it.
CollectConfigSources now records which Configuration owns each source instead
of flattening to a set, because three regimes coexist: the library, each test
(carrying its own target, defines and -march), and project.cpp, which Build
never touches and which therefore gets no command at all.
libclang resolves its builtin headers relative to its own install path, which
need not match the clang++ that wrote the PCMs. When it doesn't, every parse
dies on "'stddef.h' file not found", so -resource-dir is passed explicitly
from `clang++ -print-resource-dir`.
Two flags on each declaration replace what would otherwise become more
substring denylists: isExternC, and isForeignApi for a declaration that binds
to an entity declared outside the project root — resolved through
clang_getCursorReferenced and the same inside-the-root test the dependency
walk already uses. Parameters and fields inherit it, so an exemption covers a
whole signature rather than the one node that named the foreign entity.
Failure is never silent. A fatal diagnostic leaves a fragment that is
indistinguishable from a file declaring nothing, so it is reported as an error
instead: the rule is skipped, a finding explains why, and summary.errors makes
the run fail. --no-ast opts out deliberately and exits normally.

The clang invocation was assembled inline across four regions of Build,
interleaved with the dependency-graph walk, so nothing else could ask "what
flags does this Configuration compile with". The linter's AST layer needs
exactly that, and it cannot approximate it: a precompiled module is rejected
outright by a translation unit whose target features differ from the one that
wrote it. Dropping just -march=native produces hundreds of "compiled with the
target feature '+avx512bw' but the current translation unit is not" errors and
no usable parse, so reconstructed flags fail hard rather than degrade.
GetCompileCommand is the config-pure part: target, arch, standard,
configuration defines, module search paths, includes, user compileFlags,
optimisation and LTO. Build appends only what depends on work having happened
— dependency public flags and external dependency flags. The sub-strings it
also needs on their own (includes, defines, user flags, LTO) come back as
struct members, so the .c compile path is unchanged.
Verified by probing `command` at the equivalent point before and after and
diffing: byte-identical across all 23 configurations exercised by a full build
plus the test suite.
Two incidental simplifications fell out. pcmDir was recomputing what
Configuration::PcmDir() already returns, and cmakeBuildType is now a
one-liner. GetCompileCommand is also most of what a compile_commands.json
would need, which this repo lacks.

Replaces the linter's hand-rolled character scanning with clang's lexer.
StripComments could not see raw string literals, which was documented as a
v1 limitation but was worse than that: an odd number of quotes inside a raw
string desynchronised it for the rest of the file, hiding real code and
leaving the contents of later literals standing as if they were code. There
are 33 raw strings across 6 files here, including the two largest.
The reflow guards had the same class of bug from the other direction. They
were substring probes, so Line(n).contains("//") fired on // inside a string
literal and contains("R\"") fired on the characters R" inside a literal while
missing raw strings opened on an earlier line. Both misfire on this repo:
"MARKER" ends in R". They are now LineHasComment() and
LineHasMultiLineToken(), and two wrapped call sites in tests/Lint that had
been silently unjoinable join as a result.
libclang is dlopen'd rather than linked, so the mingw and MSVC cross-builds
keep linking and the release tarballs stay self-contained. Tokens need no
PCMs, no build flags and no prior build, and they cover preprocessor branches
that are inactive for the host — which is why the layout rules belong on
tokens rather than on an AST that would only ever see one platform's slice.
No rule behaviour was intended to change beyond the two guard fixes; lint
over this repo produced byte-identical output across the CommentStripped
swap.
Three follow-ons to the stale-build report, all cases of an identity not
capturing something that changes the output.
The host PCM cache under <cache>/crafter.build/<target>-<march>/ is shared by
every crafter-build on the machine, and freshness was a per-file mtime
comparison. That cannot tell "this PCM is newer than my source" from "this PCM
was built from different sources that happen to be newer", so a package install
and a working checkout — or two checkouts of different versions — silently
compiled their project.cpp against each other's declarations. Invalidation now
keys on a stamp over the bytes of every module source, which also covers the
case one file's mtime never could: the cached PCMs import each other, so a
change to :Interface invalidates :Clang's PCM with Crafter.Build-Clang.cppm
untouched.
Project args ApplyStandardArgs does not itself interpret are now folded into
VariantId. Such a flag typically decides what gets compiled or bundled — the
report's example is --no-webgpu dropping entries from cfg.files — and without it
both settings shared one bin dir and interleaved their outputs there, leaving a
bundle matching neither. Sorted and deduplicated so flag order doesn't split the
cache, and inherited by test Configurations.
`crafter-build clean` removes the project's bin/ and build/ trees. It
deliberately does not load project.cpp: cleaning is most often reached when
something is already wrong, and a clean that first needs the project to compile
is useless exactly then.
Adding a data member to a class in a module interface did not rebuild every
object compiled against the old layout. The build succeeded with no error or
warning and the resulting binary mixed both layouts, surfacing later as a
SIGSEGV in a destructor.
GetInterfacesAndImplementations scans a TU's `import X;` statements when the
source is declared. An import that matches neither a module in the
Configuration nor one reachable through `dependencies` was dropped on the
floor, leaving that TU with no staleness edge to the interface it consumes.
`dependencies` is frequently assigned *after* the scan — AddTest does exactly
that, resolving tests/<name>/main.cpp and only then returning a builder whose
.Dependencies() supplies the library — so consumers of a dependency's modules
routinely carried no edge at all. A layout change then rebuilt the library,
relinked the consumer, and kept the consumer's object as it was.
Unresolved names are now remembered on the partition/implementation as
pendingImports, and Configuration::ResolvePendingImports retries them against
the dependency DAG as it stands. Build() calls it immediately before comparing
mtimes, which closes the window for every caller rather than only the ones that
declare in the right order; TestBuilder::Dependencies also calls it so the
Configuration is coherent for anyone inspecting it before the build.
Resolves#27
The transforms guard themselves against comments and raw strings before
joining or rewriting a line, because pulling text up past a `//` buries it
and reflowing a multi-line literal changes the string. Those guards were
substring probes over the raw line, so they answered the wrong question:
Line(n).contains("//") fires on // inside a string literal
Line(n).contains("R\"") fires on the characters R" inside a literal, and
MISSES a raw string opened on an earlier line
Both misfire on this repo's own sources. "MARKER" ends in R", and any string
mentioning a lint-disable directive contains //. Two wrapped call sites in
tests/Lint were being left unjoined for exactly these reasons; they join now,
and the results are in this commit.
Replaced by LineHasComment() (added with the token layer) and a new
LineHasMultiLineToken(), which reports whether any token actually covering
that line spans a line boundary — a raw string or a block comment. Backed by
a per-line bitmap derived from the token cache and invalidated with it.
The guards themselves stay: joining across a real comment or a real
multi-line literal is still unsafe, and there are tests for both. What
changes is that they now fire on comments and literals rather than on the
characters that spell them.
format-concat gets narrower as a result. It used to refuse any line
containing R" and ask for a manual fix; now only a literal that genuinely
spans lines does that, because a single-line raw string reduces to R"…" in
the stripped view, fails the plain-literal test, and travels through as an
argument with its spelling intact.
Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
StripComments hand-scanned five states over raw characters and could not see
a raw string literal, which was documented as a v1 limitation. It was worse
than "does not recognise them": an odd number of quotes inside a raw string
desynchronised the scanner for the rest of the file. Simulated on the new
fixture, the old output was
auto banner = R" "hi)" \n \n ... "MARKER text"
— the code after the raw string blanked away, and the *contents* of a later
string literal left standing as if it were code. Every rule reading
CommentStripped() saw that. There are 33 raw strings across 6 files here,
including the two largest.
The replacement projects the token stream onto a copy of the buffer, blanking
comment tokens whole and the bodies of string/character literals. Editing a
copy in place makes the length-preserving contract structural rather than
something each branch has to remember, and the token extents make raw
strings, escapes, encoding prefixes and '"' all fall out for free. A raw
string reduces to R"…" so rules that bracket a literal by counting quotes
keep working. Digit separators (1'000) are excluded by requiring the text
before the quote to be an encoding prefix.
The public contract is unchanged, so no rule needed editing, and `lint` over
this repo produces byte-identical output to the previous implementation.

Adds LintContext::Tokens() and friends, backed by clang_tokenize, as the
substrate the rules will move onto. Nothing consumes it yet.
libclang is dlopen'd rather than linked: -lclang would break the mingw and
MSVC cross-builds at link time and would put a libclang.so.NN runtime
dependency into the otherwise self-contained release tarballs. The clang-c
header is used for its declarations only, and the function-pointer table is
typed with decltype so the signatures cannot drift from the real API.
Three properties this buys that the hand-rolled scanners could not have:
- a raw string literal or block comment is ONE token, so the documented
"raw string literals are not recognized" limitation goes away;
- `//` inside a literal is not a comment, so LineHasComment() replaces the
Line(n).contains("//") probes that false-positive on it;
- tokens cover preprocessor branches that are inactive for the host, since
clang_tokenize lexes rather than evaluates #if. Token rules therefore
keep seeing every platform's code, which an AST could not offer.
The parse backing the tokenizer is expected to fail on module units — no
PCMs, no build flags — and that is fine, because lexing has no semantic
prerequisites. Verified in the new tests.
LintSummary::Clean() now counts `errors`. It previously ignored them, so an
infrastructure failure that produced no findings reported clean and exited
0; a missing libclang would have been exactly that.

The browser wasm pipeline hardcoded -msimd128 for every wasm32 target and
baked a single wasm URL into index.html, so newer codegen features that
aren't yet baseline across engines (relaxed SIMD today; threads, future SIMD
revisions later) couldn't be adopted without dropping the browsers that lack
them.
Add a general, feature-parameterized mechanism owned entirely by
Crafter.Build:
- Configuration::wasmVariants declares N codegen variants (label, extra -m
flags, runtime probes). Build() compiles the baseline plus one
outputName.<label>.wasm per variant, recompiling the whole graph (incl.
dep libs + std PCM) with the variant's flags — relaxed-SIMD is per-TU
codegen, not a link switch. wasmVariantFlags folds into VariantId so each
variant's objects/PCMs land in their own build+bin dir.
- EnableWasiBrowserRuntime emits a variants.json manifest (label -> url +
probes), preferred-first with the baseline as the universal fallback.
- The shipped runtime.js runs inlined wasm-feature-detect probes
(relaxed-simd, simd, tail-call, bulk-memory, exception-handling, threads),
picks the first variant whose probes all pass, and falls back to the single
baked CRAFTER_WASM_URL when no manifest is present (backward compatible).
- EnableWasiRelaxedSimdVariant registers the relaxed-SIMD variant — the
motivating case (Chrome 114+/Firefox 120+ enable it by default; Safari
still flag-gates it as of mid-2026).
Verified end to end: a wasm32-wasip1 build emits both wasi-hello.wasm and
wasi-hello.relaxed-simd.wasm + variants.json; Firefox selects the
relaxed-simd variant and runs it.

With test.toml + ForTarget covering the cross-arch + Windows-on-Linux
cases, the env-var-driven transport runners are dead weight. This commit
removes them and the retired tests that exercised the env-var plumbing:
- TestRunner::Ssh / SshWin / Wsl factories and their copy/exec/cleanup
template machinery.
- TestRunner::Shell enum (Host/Sh/Cmd) and the ShellQuoteSh helper —
only Host shell quoting is needed once the remote shells are gone.
- TestRunner::copy / cleanup / remoteDir / argsShell fields.
- WindowsPathToWsl and the {remote_bundle}/{bin_win}/{bundle_wsl}
placeholder substitution in RunSingleTest's transport branch.
- ParseRunnerSpec narrowed from {local, cmd, ssh, sshwin, wsl} to
{local, cmd} — the override hatch is preserved, just simpler.
- tests/SshRunner, tests/WindowsViaSsh, tests/QemuUser: these tested
the CRAFTER_BUILD_RUNNER_<target> → runner plumbing that has been
replaced by ForTarget. The runner derivation is exercised every
time CrossArchAarch64 / Wasi / WindowsViaWine runs.
- tests/UnitLib: ssh/sshwin spec assertions become "throws on bogus
spec" assertions.

Vendors toml++ v3.4.0 as lib/toml.hpp and wires it into Crafter.Build-Test
to parse a declarative test.toml manifest (target/march/mtune/sysroot/
requires/timeout/args/defines). Test discovery now treats project.cpp and
test.toml as mutually exclusive: project.cpp stays the escape hatch for
outer-driver tests, test.toml gives downstream test authors a no-boilerplate
path.
Adds:
- TestRunner::Wine() and TestRunner::ForTarget(cfg) — runner is now derived
from cfg.target (Local for host, Wine for Windows-on-Linux, wasmtime for
WASI, qemu-<arch> with QEMU_LD_PREFIX for non-host Linux). The env-var
override CRAFTER_BUILD_RUNNER_<target> still wins as a power-user escape
hatch via FromEnv.
- Declarative preconditions: tool:<name>, file:<path>, env:<VAR> are
evaluated before the build; missing preconditions Skip without paying
the compile cost.
- Hard-fail-unless-declared: when a derived runner's tool is missing AND
the test didn't declare 'tool:<that>' in requires, the missing runner
is a Fail instead of a silent Skip. Surfaces broken cross-arch CI
config that previously hid as "skipped".
- Multi-target sweep: bare `crafter-build test` (no --target=) now
iterates every distinct test.toml-declared target plus the host, so
cross-arch tests run by default without the user needing to know which
targets exist. `--target=X` bypasses the sweep.
Test struct gains a `requires_` vector so project.cpp users can declare
preconditions too (matching what test.toml writes there).
Existing tests, factories (Ssh/SshWin/Wsl/Cmd), and CRAFTER_BUILD_RUNNER_*
machinery remain intact — this commit only adds; migration and deletion
follow in subsequent commits.

WASI / wasm32 target support
- Auto-detect /usr/share/wasi-sysroot on Linux when target starts_with("wasm32")
- Skip -march/-mtune for wasm (clang rejects them)
- Apply -fno-exceptions -fno-c++-static-destructors -mllvm -wasm-enable-sjlj
-D_WASI_EMULATED_SIGNAL to wasm builds (compile + std PCM, kept in sync)
- .wasm output extension in expectedOutputFor and link command
- EnableWasiBrowserRuntime(cfg): opt-in helper that drops index.html +
runtime.js next to the .wasm; runtime.js reads window.CRAFTER_WASM_URL
set in the templated index.html so a single shim handles any output name
-r run flag in the CLI: build then exec the artifact (host targets only;

CI pipeline (.forgejo/workflows/ci.yaml)
- Triggers: PR/push to master + manual dispatch
- Single arch-latest container job: install deps, bootstrap, self-rebuild,
run tests, cross-compile mingw, package both archives, upload artifacts
- Rolling 'latest' release published only on push/dispatch to master
mingw cross-compile from Linux now works end-to-end:
- ExternalDependency cache key includes target so per-target glslang builds
don't collide; CMAKE_BUILD_TYPE=Release pinned (otherwise glslang appends
'd' to lib names and breaks linking); cross-compile cmake flags
(CMAKE_SYSTEM_NAME=Windows, CMAKE_*_COMPILER_TARGET=...)
- project.cpp accepts --target=<triple>; Linux-only -Wl,--export-dynamic
and -ldl are gated; mingw glslang skips the standalone exe (its libgcc_eh
link pulls pthread which mingw doesn't link by default)
- mingw compile uses -femulated-tls so std::__once_callable etc reference
the same emutls symbols libstdc++ provides
- mingw link auto-adds -lstdc++exp -lpthread
GetCrafterBuildHome() exposed from the Platform module; LoadProject (Linux
+ Windows) now both use it instead of duplicating the resolution.
Examples reorg: hello-world, library, with-module, wasi, tests — each with
