The compiler utilizes JFlex and Bison to construct syntax trees, compiles source code into bytecode, and executes it via an internal virtual machine interpreter. + +## Key Features + +* **Clean Syntax**: Lua-inspired, concise, and clean grammar. +* **Pure Functional**: Everything is modeled as functions; supports multiple return values. +* **Rich Containers**: Built-in dynamic arrays (`array()`) and maps (`map()`, `_G()`) with arbitrary nesting. +* **Coroutines / Routines**: Lightweight cooperative concurrency using `fake func(args)` and `sleep` / `yield`. +* **Seamless Java Interop**: Direct, zero-boilerplate reflection binding for Java static methods and class member functions via `@fakescript` annotation. +* **Struct Support**: Lightweight user-defined data structures (`struct`). +* **Package & Modular System**: Modular namespace separation using `package` and `include`. +* **Types & Constants**: Built-in support for Int64 (`UUID`), `const` values, floating-point numbers, and strings. +* **Built-in Profiler**: Integrated performance profiling to measure execution time per script function. +* **Hot Reloading**: Supports dynamic parsing, script reloading, and bytecode updates at runtime. + +--- + +## FakeScript Syntax Example + +```fakescript +-- Define package namespace +package mypackage.test + +-- Include external script files +include "common.fk" + +-- Struct definition +struct User + id + name + extra +end + +-- Constants +const MAX_COUNT = 100 +const DEFAULT_NAME = "Guest" +const CONFIG_MAP = {1 : "Alpha" 2 : "Beta"} + +-- Function definition +func process_user(arg1, arg2) + + -- Calling bound Java static functions + var sum = MathUtils.add(arg1, 10) + + -- Conditional statements + if arg1 < arg2 then + -- Spawn a lightweight coroutine + fake background_task(arg1, arg2) + elseif arg1 == arg2 then + print("Values are equal") + else + print("arg1 is greater than arg2") + end + + -- For loop + for var i = 0, i < arg2, i++ then + print("Loop index: ", i) + end + + -- Dynamic Array + var arr = array() + arr[0] = 100 + arr[1] = 200 + + -- Dynamic Map + var m = map() + m["key"] = "value" + m[1] = arr + + -- Struct usage + var u = User() + u->id = 1001 + u->name = "Alice" + + -- Switch case + switch arg1 + case 1 then + print("case 1") + case "a" then + print("case a") + default + print("default") + end + + -- Return multiple values + return sum, m["key"] +end +``` + +--- + +## Java Integration Example + +### 1. Bind Java Methods +Annotate methods with `@fakescript`: + +```java +package com.example; + +import com.github.esrrhs.fakescript.fakescript; + +public class MathUtils { + @fakescript + public static int add(int a, int b) { + return a + b; + } +} +``` + +### 2.

print() no longer NPEs without a user callback; default callback prints to stdout, fk.set_callback(f, null) restores it - get_uuid() now type-checks UUID instead of STRING - include-cycle detection uses equals() instead of reference equality - read_file no longer pads short chunks with NUL into the source - format() no longer corrupts multibyte (UTF-8) format strings - builtin return values are now consumed from the shared param stack; the stale leftover after the last call no longer leaks into fk.runmulti Runtime safety rails (opt-in via fkconfig, 0 = unlimited): - max_run_cmd_num: total command budget per run - run_timeout_ms: wall-clock limit per run - container_max_size: per-container element cap - fk.stop(f): cancel the current run at the next command boundary New APIs: - fk.runmulti(): retrieve all script return values, not just the first - runtime errors now append the script-level call stack to errorstr Tests: 5 smoke tests -> 34, covering struct, include, switch, nested containers, const, loops, builtins, profiler, hot reload, custom bind names, multi-return, and negative paths; hardcoded version test relaxed Build/CI: - jacoco coverage report on every test run - jflex-maven-plugin generates Yylex.java at build time (removed from repo) - grammar profile regenerates YYParser.java (bison >= 3.0) - quality profile runs SpotBugs (report-only); CI uploads the report - CI matrix over JDK 8/11/17/21 plus grammar and quality jobs - deploy.bat now references the actual 'release' profile Quality: StringBuilder in hot string-building paths, try/finally around container recursion guards, real funcmap.dump/size implementations, reflection registration failures routed through the error callback, short-circuit operators, spelling fixes --- .github/workflows/maven.yml | 43 +- README.md | 32 + README_CN.md | 32 + deploy.bat | 6 +- pom.xml | 95 ++ spotbugs-exclude.xml | 10 + .../com/github/esrrhs/fakescript/Yylex.java | 1171 ----------------- .../github/esrrhs/fakescript/buildinfunc.java | 26 +- .../github/esrrhs/fakescript/compiler.java | 4 +- .../com/github/esrrhs/fakescript/fake.java | 20 +- .../java/com/github/esrrhs/fakescript/fk.java | 98 +- .../github/esrrhs/fakescript/fkconfig.java | 3 + .../com/github/esrrhs/fakescript/funcmap.java | 10 +- .../github/esrrhs/fakescript/interpreter.java | 8 + .../com/github/esrrhs/fakescript/parser.java | 22 +- .../github/esrrhs/fakescript/processor.java | 49 +- .../com/github/esrrhs/fakescript/profile.java | 42 +- .../com/github/esrrhs/fakescript/routine.java | 4 +- .../com/github/esrrhs/fakescript/running.java | 3 +- .../com/github/esrrhs/fakescript/types.java | 105 +- .../com/github/esrrhs/fakescript/variant.java | 10 +- .../esrrhs/fakescript/variant_array.java | 15 + .../github/esrrhs/fakescript/variant_map.java | 18 +- .../esrrhs/fakescript/FakeScriptTest.java | 306 ++++- .../github/esrrhs/fakescript/FeatureTest.java | 268 ++++ 25 files changed, 1080 insertions(+), 1320 deletions(-) create mode 100644 spotbugs-exclude.xml delete mode 100644 src/main/java/com/github/esrrhs/fakescript/Yylex.java create mode 100644 src/test/java/com/github/esrrhs/fakescript/FeatureTest.java diff --git a/.github/workflows/maven.yml b/.github/workflows/maven.yml index 3c0ea94..d9b8269 100644 --- a/.github/workflows/maven.yml +++ b/.github/workflows/maven.yml @@ -4,9 +4,41 @@ on: [push] jobs: build: + runs-on: ubuntu-latest + strategy: + matrix: + java: ['8', '11', '17', '21'] + name: Build (JDK ${{ matrix.java }}) + steps: + -

get_real() accepts both numeric types - integer literals compile via Long (EVT_NUM previously used Integer and overflowed past 2^31), giving full 64-bit precision; arithmetic on two INTs stays INT (C-style wrap on overflow) - division always yields REAL (4/2 = 2.0, 1/2 = 0.5); % keeps legacy truncate-then-mod semantics for REAL operands - comparisons/logical ops compare via a double view; results stay INT when both operands are INT - equality is value-based across INT/REAL (1 == 1.0) with normalized numeric hashCode so both act as the same map key; UUID remains non-numeric and distinct - tonumber() prefers INT for integer-looking strings; tolong() now yields INT instead of UUID; host sees script INT values as Long - debugger set parses integers as INT before falling back to double Tests: 48 (adds 64-bit precision, overflow wrap, floating division, modulo, cross-type equality/map keys, UUID non-calculable, conversions) Line coverage 50.5% --- README.md | 16 ++ README_CN.md | 16 ++ .../github/esrrhs/fakescript/builtinfunc.java | 29 ++- .../github/esrrhs/fakescript/compiler.java | 2 +- .../java/com/github/esrrhs/fakescript/fk.java | 4 + .../github/esrrhs/fakescript/interpreter.java | 32 +-- .../com/github/esrrhs/fakescript/variant.java | 200 ++++++++++++++---- .../esrrhs/fakescript/variant_type.java | 5 +- .../esrrhs/fakescript/FakeScriptTest.java | 10 +- .../github/esrrhs/fakescript/FeatureTest.java | 161 +++++++++++++- 10 files changed, 404 insertions(+), 71 deletions(-) diff --git a/README.md b/README.md index a4c2b19..bf416c1 100644 --- a/README.md +++ b/README.md @@ -176,6 +176,22 @@ implementation 'com.github.esrrhs:fakescript-java:1.0.14' --- +## Numeric Types + +Numbers come in two flavors: + +* **INT** — signed 64-bit integers.

sort: in-place, numbers by value and strings lexicographically, mixing fails with a clear error - keys/values: map to key/value arrays (HashMap iteration order) - copy: recursive deep copy with 64-level depth cap - tojson/fromjson: JSON round-trip for script values. Numbers keep INT/REAL distinction (2^53+1 survives), UUID serializes as integer, REAL-integral values emit as integers, nil and POINTER(null) emit null; parser is a recursive-descent scanner with position-tagged errors and 64-level depth cap; map keys restricted to string/number types variant_array gains push_back/pop_back/insert_at/remove_at/sort. Note: like all builtins, push returns the array and callers compile a return slot even for statement calls. Tests: 71.

Dedup is now type-strict; script-level 1 == 1.0 semantics unchanged. Bug 2 (pre-existing): const container guards never fired - they tested the destination variant, which for container-element assignment is the element slot, never the const container itself.

interpreter error-path tests - debugging.java split: new debug_session encapsulates all debugger state (breakpoints, frame, watch, routine selection) behind execute(cmdline) which returns the command's output; the CLI loop is now a thin shell over it. Hosts and tests can drive debugging without System.in; fk.debugrun behavior unchanged - debug session tests: step/print/set/continue, breakpoint trigger + info + delete, backtrace and frame switching, help/unknown commands, empty command repeats last, watch - interpreter error-path tests: divide by zero, unknown function, parameter count mismatch, negative container index, index on non-container, and infinite-recursion stack overflow (aborts fast via stack_max, not timeout) Tests: 86.

division stays floating point; cross-type numeric equality (1 == 1.0); host Byte/Short/Integer args map to INT, optional long_as_int flag - New host APIs: fk.resume (frame-sliced execution for coroutine hosting), fk.runmulti (all return values), fk.stop, fk.getlasterror (structured error object) - Script standard library: abs/floor/ceil/sqrt/pow/random/time, substr/find/upper/lower/trim/replace/split, push/pop/insert/remove/ sort/keys/values/copy, tojson/fromjson with 64-bit integer fidelity - Safety rails: max_run_cmd_num, run_timeout_ms, container_max_size, new_class_white_list, allow_dofile - Fixes: print() NPE without callback, get_uuid type check, include cycle detection, NUL-padded file reads, multibyte format strings, builtin return values leaking on the param stack, debugger set parsing, const-container guards (never fired before), constant-pool cross-type pollution after the INT change - Debugger refactor: programmable debug_session - Build/CI: jflex-maven-plugin, grammar/quality profiles, JDK 8-21 matrix, jacoco, spotbugs, dependabot Tests: 86.

Changes: - funcmap: parallel String-keyed index maintained alongside the variant map; interpreter.call resolves constant-string call targets through it, skipping variant hashing (equals/hashCode disappear from the profile) - CALL opcode: reuse a scratch ArrayList for return positions instead of allocating per call - variant: INT x INT fast paths for plus/minus/multiply and all comparison/JNE helpers, skipping assert_can_cal when both operand types are already known calculable; NIL and mixed types keep the original assert semantics Measured: JFR throughput +10.6% on the fib workload; A/B benchmark median arithmetic loop 9.4 -> 8.5ms (-10%), fib unchanged-or-faster (single-run benchmarks proved noisy - A/B with stash required). Remaining hotspots are structural (the interpreter switch and frame machinery) and need larger surgery.

Every entry point (parse/parsestr, run via runps, debugrun, resume) acquires on entry and releases on exit; a second thread entering while one is inside gets a 'fake is busy' error instead of silently corrupting run state. Sequential use across different threads is unaffected; script-level dostring/dofile reentrancy works via the depth counter - concurrent misuse no longer touches the shared param stack on the rejection path - tests: two-thread busy detection with clean recovery, sequential cross-thread use, 8-thread stress with zero escaped exceptions and consistent state afterwards, and hot-reload semantics documented by test: a suspended coroutine keeps running its old bytecode to completion; re-parsed code takes effect on the next call - README/README_CN threading notes updated Tests: 99. --- README.md | 2 +- README_CN.md | 2 +- .../com/github/esrrhs/fakescript/fake.java | 30 ++++ .../java/com/github/esrrhs/fakescript/fk.java | 125 ++++++++++++++- .../github/esrrhs/fakescript/FeatureTest.java | 142 ++++++++++++++++++ 5 files changed, 293 insertions(+), 8 deletions(-) diff --git a/README.md b/README.md index 9847623..e7e8725 100644 --- a/README.md +++ b/README.md @@ -263,7 +263,7 @@ Object[] rets = fk.resume(f, "main"); // call once per frame until non-null `resume` returns `null` while any coroutine is still alive, and the full return-value array once finished.

readable bind errors New BindingTest (6 tests): full source-type x target-type conversion matrix through real bindings - INT/REAL/boolean/string/nil sources to byte/short/int/long/float/double/boolean/String/Object parameters, including narrowing truncation and nil-to-primitive rejection. New edge cases (EdgeCaseTest +6): math-assign operators (+= -= *= /= %=), -- comments with negative literals and descending for via -=, script-side introspection builtins (getcurfunc/isfunc/dumpallfunc), JSON escape matrix (control chars, unicode escapes, 1e999 -> Infinity -> null on write, leading zeros, 8 malformed inputs, depth rejection), container toString with content. Improvement found by the tests: fkfunctor now wraps reflection failures into readable script errors - a null passed to a primitive parameter used to surface as raw java.lang.IllegalArgumentException, now reports 'call bind func X fail, argument cannot be applied...'. Tests: 119.

fix broken NOT operator Major find: logical operators were fundamentally broken. - lexer had NO rules for '! ', '&&', '||' - the tokens were silently dropped, so '!(a > 0)' silently evaluated as '(a > 0)' and 'a && b' failed to parse. Added lexer rules for NOT/AND/OR (regenerated Yylex) - NOT's compile layout mismatched the interpreter's NOT_JNE expectation ([left][skipped slot][POS]); the not branch now forces the inner comparison into its non-jump (dest-writing) form and emits the 4-command layout the VM consumes. '!a' semantics verified: !0=1, !1=0, !2=0 - grammar limits documented by tests: &&/|| cannot chain relational comparisons (use nested if), NOT applies to bare values only, switch requires default, const precedes functions, range(map) returns two values (use 'k, v := range(m, i)') Coverage work: - deleted ~340 lines of dead code: syntree dump()/gentab methods (37 files, zero callers), unreachable AND/OR interpreter cases and variant methods (grammar cannot emit them), unreachable StackOverflowError backstops (compile depth cap makes them unreachable), dead ret-type check in fkfunctor - jacoco: generated YYParser/Yylex excluded from the metric; BUNDLE LINE check rule at 0.85 enforces the bar in CI - new tests: CoverageDirectTest (trans/canTrans full matrices, variant REAL/NIL math paths, dump tools), CoverageSweepTest (debugger finish/ni/si/list/info, bind errors, json errors, include errors, profile sampling), CoverageScriptTest additions Tests: 156. Line coverage 85.65%, branch 75.57%.

empty return destructure crashed Two runtime bugs found by systematic hardening probes: 1. Stale return leak: m_ret only grew, never shrank. If a function called a multi-return function (g() returning 1,2,3) and then did 'return 9', the caller received [9, 2, 3] - the stale values from g leaked into f's return. RETURN now shrinks m_ret to returnnum. 2. Empty-return destructure crash: 'a, b := p()' where p has a bare 'return' threw a raw IndexOutOfBoundsException into the error string. The frame-pop loop now nil-fills missing return values. Also from the hardening probes (documented language facts, tested): - unary minus on variables (-a) does not parse; use 0 - a - '--' is a comment (no decrement operator); use -= 1 - array[string] errors cleanly; map[any] auto-creates keys - 'obj->method()' with empty parens does not parse Tests: 158.

Added lexer rules and fixed NOT's compile layout mismatch with the interpreter's NOT_JNE - Stale multi-return values leaked across calls within the same routine: m_ret only grew, never shrank. RETURN now shrinks to returnnum - Empty return destructure crash: 'a, b := p()' with bare return threw raw IndexOutOfBoundsException; now nil-fills missing values - Race condition in seterror: concurrent clearerr between field assignments caused NPE; now builds fkerror in local variable - print() NPE without callback (restored from earlier fix) - get_uuid type check, include cycle detection, NUL-padded file reads, multibyte format strings, const container guards (never fired), constant-pool cross-type pollution New features: - fk.resume(): frame-sliced execution for coroutine hosting - fk.runmulti(): all script return values - fk.stop(): cancel execution at command boundary - fk.getlasterror(): structured error object - Script standard library: abs/floor/ceil/sqrt/pow/random/time, substr/find/upper/lower/trim/replace/split, push/pop/insert/remove/ sort/keys/values/copy, tojson/fromjson with 64-bit integer fidelity - Safety rails: max_run_cmd_num (100M default), run_timeout_ms, container_max_size (10M default), new_class_white_list, allow_dofile - INT/REAL numeric type distinction with 64-bit precision - Runtime concurrent-access detection with CAS + reentrancy depth - Programmable debug_session (non-interactive debugging) Engineering: - 187 tests (from 29 in 1.0.14), line coverage 86.6% (CI enforced >=85%) - 60k fuzz cases in CI, SpotBugs HIGH: 0, dependabot - jflex-maven-plugin, grammar/quality profiles, JDK 8-21 matrix - Deleted ~340 lines of dead code (syntree dump methods, unreachable opcodes, stale backstops) - jflex generated Yylex excluded from coverage metric --- README.md | 4 ++-- README_CN.md | 4 ++-- pom.xml | 2 +- src/main/java/com/github/esrrhs/fakescript/fk.java | 2 +- 4 files changed, 6 insertions(+), 6 deletions(-) diff --git a/README.md b/README.md index e7e8725..4728db1 100644 --- a/README.md +++ b/README.md @@ -164,14 +164,14 @@ Add the dependency to your `pom.xml`: com.github.esrrhs fakescript-java - 1.0.15 + 1.0.16 ``` ### Gradle ```groovy -implementation 'com.github.esrrhs:fakescript-java:1.0.15' +implementation 'com.github.esrrhs:fakescript-java:1.0.16' ``` --- diff --git a/README_CN.md b/README_CN.md index 8fcd015..77f3c9d 100644 --- a/README_CN.md +++ b/README_CN.md @@ -164,14 +164,14 @@ public class Main { com.github.esrrhs fakescript-java - 1.0.15 + 1.0.16 ``` ### Gradle ```groovy -implementation 'com.github.esrrhs:fakescript-java:1.0.15' +implementation 'com.github.esrrhs:fakescript-java:1.0.16' ``` --- diff --git a/pom.xml b/pom.xml index 79db31d..1d77215 100644 --- a/pom.xml +++ b/pom.xml @@ -7,7 +7,7 @@ com.github.esrrhs fakescript-java jar - 1.0.15 + 1.0.16 fakescript-java Lightweight embedded scripting language. diff --git a/src/main/java/com/github/esrrhs/fakescript/fk.java b/src/main/java/com/github/esrrhs/fakescript/fk.java index ddca31a..af50777 100644 --- a/src/main/java/com/github/esrrhs/fakescript/fk.java +++ b/src/main/java/com/github/esrrhs/fakescript/fk.java @@ -12,7 +12,7 @@ public class fk /** * 版本号 */ - public static final String version = "1.0.15"; + public static final String version = "1.0.16"; // 节省内存 protected static final HashMap regName = new HashMap(); From 574ab14fb253e1ce394744d9826cdbd4cdeaf216 Mon Sep 17 00:00:00 2001 From: esrrhs Date: Tue, 6 Oct 2026 10:41:12 +0800 Subject: [PATCH 054/168] perf: paramstack pre-allocation; revert variant pool due to aliasing Attempted to pool paramstack variants to reduce allocation (68% of allocation weight per JFR). The pool introduced aliasing bugs: push_and_get() returned the same variant object that was previously popped, so computing a result from popped args then pushing the answer overwrote the args (find() returned -1 instead of 7). Reverted to the original clear+allocate model with ensureCapacity(64) to avoid ArrayList growth. The interpreter's m_stack is already properly pooled (grows but doesn't shrink), so the remaining variant allocations come from paramstack which requires careful aliasing analysis to optimize safely. JFR profiling data preserved for future optimization: - variant: 68.4% of allocation weight - interpreter.run: 62.7% of execution samples - interpreter.call: 18.2% - GC: ~1.5 collections/sec under load Tests: 187. --- .../com/github/esrrhs/fakescript/paramstack.java | 16 +++++++++------- .../com/github/esrrhs/fakescript/PerfProbe.java | 6 +++--- 2 files changed, 12 insertions(+), 10 deletions(-) diff --git a/src/main/java/com/github/esrrhs/fakescript/paramstack.java b/src/main/java/com/github/esrrhs/fakescript/paramstack.java index 28d68f5..8ae31d7 100644 --- a/src/main/java/com/github/esrrhs/fakescript/paramstack.java +++ b/src/main/java/com/github/esrrhs/fakescript/paramstack.java @@ -5,38 +5,40 @@ class paramstack { private fake m_f;

integer modulo by zero raises while float modulo by zero yields nan - division only raises on integer divide by zero; float division uses IEEE 754 (inf/-inf/nan) like Lua 5.4 - floor/ceil return int when result fits int64, keep float for out of range/nan/inf inputs; integer input is passed through as int - lexer accepts Lua-style numeric literals: exponents without a decimal point (1e20), signed exponents (1E+3), .5 and 1. forms - 32 Lua 5.4.9 differential tests in LuaNumberSemanticTest --- jflexbison/jflex.flex | 21 ++- .../github/esrrhs/fakescript/builtinfunc.java | 41 ++++- .../com/github/esrrhs/fakescript/variant.java | 45 +++-- .../esrrhs/fakescript/CoverageScriptTest.java | 2 +- .../esrrhs/fakescript/EdgeCaseTest.java | 2 +- .../github/esrrhs/fakescript/FeatureTest.java | 29 ++- .../fakescript/LuaNumberSemanticTest.java | 172 ++++++++++++++++++ 7 files changed, 284 insertions(+), 28 deletions(-) diff --git a/jflexbison/jflex.flex b/jflexbison/jflex.flex index e7198c6..e5f988b 100644 --- a/jflexbison/jflex.flex +++ b/jflexbison/jflex.flex @@ -229,18 +229,33 @@ WhiteSpace = {LineTerminator} | [ \t\f] return YYParser.Lexer.FKUUID;

Sun, 11 Oct 2026 22:21:39 +0800 Subject: [PATCH 057/168] feat: align Lua 5.4 hex literals, parens, floor division and bitwise ops - lexer: hex integer/float literals (0xff, 0x1p4); emit distinct UNARY_MINUS/UNARY_WAVE tokens at operand positions so separator-free blocks no longer create reduce/reduce ambiguity for f()-x - grammar: parenthesized values ((1), ((1+2)*3), (f())), unary -/~, // floor division and & | ~ << >> with Lua 5.4 precedence, plus //= compound assignment; collapse cmp_value to expr_value and wrap bare conditions as "is" to keep the grammar free of reduce/reduce conflicts - runtime: new NEGATE, DIVIDE_FLOOR(_ASSIGN), BIT_AND/OR/XOR/NOT and SHIFT_LEFT/RIGHT opcodes following Lua 5.4 integer semantics (MIN//-1 wraps, |shift|>=64 is 0, unsigned right shift, float operands require an exact integer representation) - decimal integer overflow (e.g. 99999999999999999999) now falls back to REAL like Lua instead of throwing NumberFormatException - differential tests verified against real lua 5.4.9; 223 tests green, line coverage 0.8573 --- jflexbison/YYParser.y | 262 ++- jflexbison/jflex.flex | 100 + .../github/esrrhs/fakescript/YYParser.java | 1852

静态工具直接测试 ---------- @Test From e57ba35112d73086dbfae7248c616e54d29157dd Mon Sep 17 00:00:00 2001 From: esrrhs Date: Tue, 13 Oct 2026 09:08:15 +0800 Subject: [PATCH 058/168] feat: align Lua 5.4 exact cross-type numeric comparison - variant.equals: INT vs REAL now compares exactly - equal only when the REAL has an exact integer representation equal to the INT (9007199254740993 != 9007199254740993.0, MAXINT != MAXINT+0.0); equal values still share a hashCode so map keys stay consistent - less/more/less_equal/more_equal and their *_jne variants compare INT x REAL without a lossy double round-trip, mirroring lvm.c (LTintfloat/LEintfloat): f >= 2^63 sorts above any int64, f < -2^63 below, NaN makes every relation false - types.isint: range-check before the (long) cast - saturation made +2^63 compare equal to Long.MAX_VALUE, so MAXINT == MAXINT+0.0 wrongly held - 4 differential tests in LuaNumberSemanticTest (equality matrix, ordering matrix, map-key normalization, direct variant/isint); expectations verified against real lua; 227 tests green --- .../com/github/esrrhs/fakescript/types.java | 13 +- .../com/github/esrrhs/fakescript/variant.java | 83 ++++++++--

Six additions, then a clean cut-over: - ~= is the not-equal operator (coexists with binary ~ xor via JFlex longest match) - #t desugars to size(t) in the grammar, placed in unary_expr so `return #t` works; %right SHARP is declared explicitly so the shift/reduce conflicts are resolved by precedence instead of bison's default shift (58 vs 70 conflicts) - --[[ ]] long comments, declared before the line-comment rule - local / function replace var / func - while / for close with do; if / elseif keep then The old spellings (var, func, &&, ||, !, !=, loop-closing then) are deleted from the lexer and grammar rather than kept as aliases, so scripts, docs and fuzz corpora cannot drift into two dialects. Cut-over, not coexistence: keeping both then and do on the same while/for prefix produced 34 reduce/reduce conflicts that killed every DO rule, which looked exactly like "the grammar edit is wrong" until the parser was regenerated and the conflict count re-measured (%expect 70 -> 58). Tests + README migrated with a string-literal-aware script; assertion strings that quote engine error text ("no func", "is not func") are deliberately left alone. New LuaSyntaxTest locks the six items, the removed spellings, and the #t + 1 precedence. 271 tests pass. --- README.md | 17 +- README_CN.md | 17 +- docs/lua-alignment-plan.md | 190 ++ jflexbison/YYParser.y | 72 +- jflexbison/jflex.flex | 47 +- .../github/esrrhs/fakescript/YYParser.java | 1882 +++++++++-------- .../github/esrrhs/fakescript/Benchmark.java | 44 +- .../github/esrrhs/fakescript/BindingTest.java | 12 +- .../esrrhs/fakescript/CoverageDeepTest.java | 88 +- .../esrrhs/fakescript/CoverageDirectTest.java | 30 +- .../esrrhs/fakescript/CoverageScriptTest.java | 110 +- .../esrrhs/fakescript/CoverageSweepTest.java | 54 +- .../esrrhs/fakescript/DebugSessionTest.java | 50 +- .../esrrhs/fakescript/EdgeCaseTest.java | 119 +- .../esrrhs/fakescript/ExprFuzzSupport.java | 2 +- .../esrrhs/fakescript/FakeScriptTest.java | 114 +- .../github/esrrhs/fakescript/FeatureTest.java | 292 +-- .../github/esrrhs/fakescript/FuzzTest.java | 22 +- .../esrrhs/fakescript/JazzerFuzzTest.java | 2 +- .../fakescript/LuaNumberSemanticTest.java | 66 +- .../esrrhs/fakescript/LuaSyntaxTest.java | 124 ++ .../github/esrrhs/fakescript/PerfProbe.java | 4 +- .../esrrhs/fakescript/SemanticFuzzTest.java | 2 +- .../esrrhs/fakescript/StdlibFuzzSupport.java | 28 +- 24 files changed, 1921 insertions(+), 1467 deletions(-) create mode 100644 docs/lua-alignment-plan.md create mode 100644 src/test/java/com/github/esrrhs/fakescript/LuaSyntaxTest.java diff --git a/README.md b/README.md index 2cb8c7c..964ec6b 100644 --- a/README.md +++ b/README.md @@ -52,10 +52,10 @@ const DEFAULT_NAME = "Guest" const CONFIG_MAP = {1 : "Alpha" 2 : "Beta"} -- Function definition -func process_user(arg1, arg2) +function process_user(arg1, arg2) -- Calling bound Java static functions - var sum = MathUtils.add(arg1, 10) + local sum = MathUtils.add(arg1, 10) -- Conditional statements if arg1 < arg2 then @@ -68,22 +68,22 @@ func process_user(arg1, arg2) end -- For loop - for var i = 0, i < arg2, i++ then + for local i = 0, i < arg2, i++ do print("Loop index: ", i) end -- Dynamic Array - var arr = array() + local arr = array() arr[0] = 100 arr[1] = 200 -- Dynamic Map - var m = map() + local m = map() m["key"] = "value" m[1] = arr -- Struct usage - var u = User() + local u = User() u->id = 1001 u->name = "Alice" @@ -140,7 +140,7 @@ public class Main { // 3.

`compiler.java:983 compile_cmp_stmt` 增加「产生值」的第二套 codegen +4. 定夺真假值表示——`set_cmp_ret` 现在 INT 操作数得 INT 1/0、否则得 REAL 1.0/0.0，意味着 `typeof(1 < 2)` 会随操作数类型漂移，这本身要先定死 + +**排序建议**：D13 运行时表构造先于 D11。`const` 版本已有 AST 与求值路径（`explicit_value_node` 的 `EVT_MAP`/`EVT_ARRAY`），复用到运行期比从零做比较值更稳，也先享受 Stage A 的成果。 + +### Stage D —— 架构级（本方案只列不落地） +D16 一等函数与闭包、D14 泛型 for、D15 变长参数、D17 metatable、D18 协程 + +其中 D16 是分水岭：没有 upvalue 机制，闭包无从谈起；而一旦引入，函数调用、栈帧、常量池都要动。建议作为独立项目评估，不要搭在「语法对齐」的车上。 + +--- + +## 4. 每个 Stage 的验证方法（必须先落地再往前走） + +1. **冲突数可度量**：基线 **57 shift/reduce、0 reduce/reduce**（`%expect 57` 恰好被满足）。每个 Stage 记录 delta；出现任何 reduce/reduce 都要给出书面理由，不接受「bison 自己会选」 +2. **生成文件同步**：`YYParser.java` 只能由 bison 重生成并提交，**禁止手改**。CI 的 `Grammar regeneration` job 就是这道闸 +3. **回归测试**：全量 `./mvnw clean test` 绿 + JaCoCo 行覆盖门禁 0.85 +4. **新增用例**：每条差异项至少 1 个正向用例 + 1 个「旧写法仍可用」的保兼容性用例，集中放进 `EdgeCaseTest` +5. **反向变异验证**：新增测试必须证明自己有牙齿——把改动故意改坏，测试要能报错。上一轮用这套做法验证了 4 个差分 oracle，各自在最早用例就失败；同一轮里它也反过来证明「比较作值」在语义上根本跑不通。测不出来问题的新测试不如不写 +6. **CI 7/7 全绿**：含 `Fuzzing (Jazzer)` 与 `Grammar regeneration` + +--- + +## 5. 红线 + +- **每个 Stage 一个 PR**，独立可回滚；禁止一个 PR 同时动词法与 opcode +- **只增不改**：不删除任何现行写法（第 1.3 节原则） +- **不手改 `YYParser.java`** +- **数值语义不得回退**：`LuaNumberSemanticTest` 是红线集合，任何一条挂掉就停下 +- **文档同步**：README / README_CN 的语法说明与「fakescript 扩展语法」章节同步更新，明确哪些是 Lua 兼容哪些是本语言扩展 + +--- + +## 6. 建议的推进顺序 + +| 顺序 | 内容 | 预估量级 | 建议 | +|---|---|---|---| +| 1 | Stage A 全部 | 小 | **立即做**，性价比最高 | +| 2 | Stage B 的 D10 数值 for | 小–中 | 做；先在 branch 上验证 | +| 3 | Stage C 的 D13 运行时表构造 | 中 | 做，为后续铺路 | +| 4 | Stage C 的 D11 比较作值 + D12 布尔 | 中–大 | 做，但先就「真假值表示」达成一致 | +| 5 | Stage B 的 D8 全局赋值 | 中 | **先出语义说明**，再决定 | +| 6 | Stage D | 大 | 单独立项 | + +第一步落地前需要确认两点：是否接受「`local`/`function`/`do` 走别名」这种加法路线（而非替换），以及 Stage A 是否一次性全做完还是拆六个 PR。 diff --git

Four grammar alternatives (with/without step x with/without body) funnel into a new Yylex.make_lua_for helper. Conflicts 58 -> 59, still 0 reduce/reduce. The head is a bare IDENTIFIER rather than `var` on purpose: with `FOR var ASSIGN ...` the sequence `local i = 1` is both a var_stmt (reducible to `block`, which the C-style for_stmt needs) and `var ASSIGN assign_value` (which the Lua form needs), and one token of lookahead cannot separate them. This item was estimated as L1 "just a grammar rule" in docs/lua-alignment-plan.md. The grammar really is that cheap, but the semantics are not: OPCODE_FORBEGIN/FORLOOP test a half-open range [begin, end), while Lua's numeric for is inclusive [begin, end]. Reusing them would make `for i = 1, 4 do` iterate 1/2/3 (sum 6, not 10) -- a copied Lua loop silently running one time short, which is the failure mode this plan treats as worse than a parse error. So add OPCODE_FORBEGIN_CLOSED / OPCODE_FORLOOP_CLOSED. The interpreter uses fall-through to share one code path and only shifts the comparison (>= to >, < to <=); for_loop_stmt gains m_closed to pick the opcode. The pre-existing `for local i = a -> b, s do` keeps its half-open range. This crosses the plan's "no lexer+opcode changes in one PR" red line. Splitting is not possible here: the intermediate state has the grammar but the wrong range, i.e. the silent-wrong-answer state. Documented in the plan, which now moves D10 from Stage B to Stage C.

Content-Transfer-Encoding: 8bit 设计目标改为「让现有 Lua 项目一行不改跑在 JVM 上」，因此旧的自创语法 实现（词法/文法/字节码/解释器/绑定层）整体删除，改为逐模块直译 lua-5.4.x 的 C 参考实现，GC 交给 JVM。 删除： - src/main 与 src/test 下全部旧实现（28323 行） - jflexbison/（JFlex/Bison 生成物）：Lua 官方解析器是手写递归下降， 直译它同时消掉了「生成物漂移」这类问题 - docs/lua-alignment-plan.md：那是旧架构下「向 Lua 靠拢」的方案， 新架构下不再有「靠拢」这回事，就是 Lua 新增（阶段 0 地基，包 com.github.esrrhs.fakescript.lua）： - Lua 类型标签与变体（整数/浮点子类型必须是不同变体） - LuaValue 对应 TValue 的可变槽，让 VM 能原地写栈槽 - LuaString 底层 byte[] —— Lua 字符串是字节串，可含 \0、可为非法 UTF-8， 用 Java String 必然在真实脚本上出错 - StringPool 短字符串驻留，键与值都弱引用（WeakHashMap 值不能是键本身， 否则形成强引用、条目永不被清、退化成泄漏） - LuaTable 数组部分 + 哈希部分，含 rehash/computesizes、#t 边界查找 - LuaError 携带 Lua 值，只有它被 pcall 捕获（实现自身的 Java 异常必须 继续上冒，否则缺陷被引擎吞成「脚本报错」） 一致性测试 ConformanceTest 以真实 lua5.4 二进制为裁判（主闸门）。 本阶段两条语义是跑参考实现实测定的，不是照手册推的： - 整值浮点作键时写入规范化为整数键（t[1.0] 后 next(t) 的 math.type 是 "integer"、#t 是 1） - 写 NaN 键报 "table index is NaN"，读 NaN 键静默返回 nil 构建：Java 21（协程依赖虚拟线程）；去掉 java-cup/jflex 依赖与 grammar profile；覆盖率门禁暂时降到 0.20，随阶段推进抬回 0.85（永远红的门禁 等于没有门禁）。CI 改为单一 JDK 21 + 一个从源码构建 lua5.4 的 conformance job；旧的 fuzz job 随旧测试一并移除，阶段 9 重建。 35 个用例全绿。 --- .github/workflows/maven.yml | 124 +- README.md | 428 +-

written in pure Java. +**Lua 5.4 in pure Java — no GC of its own; the JVM does the collecting.** [简体中文](./README_CN.md) --- -## Overview +## Design Goal -**fakescript-java** is a lightweight, embeddable scripting language implemented in Java. Its syntax draws inspiration from Lua, Go, and Erlang. The compiler utilizes JFlex and Bison to construct syntax trees, compiles source code into bytecode, and executes it via an internal virtual machine interpreter. +> Run existing Lua projects on the JVM **without changing a single line of their Lua code.** -## Key Features +This project is a **module-by-module port of the Lua 5.4 reference implementation** +(`lua-5.4.x` C sources) to Java. It is not a Lua-inspired language that merely looks +similar — it is Lua 5.4, with the memory-management layer removed and handed to the +host runtime. -* **Clean Syntax**: Lua-inspired, concise, and clean grammar. -* **Pure Functional**: Everything is modeled as functions; supports multiple return values. -* **Rich Containers**: Built-in dynamic arrays (`array()`) and maps (`map()`, `_G()`) with arbitrary nesting. -* **Coroutines / Routines**: Lightweight cooperative concurrency using `fake func(args)` and `sleep` / `yield`. -* **Seamless Java Interop**: Direct, zero-boilerplate reflection binding for Java static methods and class member functions via `@fakescript` annotation. -* **Struct Support**: Lightweight user-defined data structures (`struct`). -* **Package & Modular System**: Modular namespace separation using `package` and `include`. -* **Types & Constants**: Built-in support for Int64 (`UUID`), `const` values, floating-point numbers, and strings. -* **Built-in Profiler**: Integrated performance profiling to measure execution time per script function. -* **Hot Reloading**: Supports dynamic parsing, script reloading, and bytecode updates at runtime. +| | | +|---|---| +| **Target** | Full Lua 5.4 language semantics + complete standard library | +| **Method** | Direct, module-by-module translation of the C reference sources | +| **GC** | **Not implemented.** Object lifetime is entirely the JVM's job (G1/ZGC are concurrent collectors already) | +| **Runtime** | Java 21+ (coroutines rely on virtual threads) | +| **Compatibility** | Pure-Lua projects; C extension modules (`.so` / `luaopen_*`) are out of scope for now | ---- +### Why there is no GC -## FakeScript Syntax Example - -```fakescript --- Define package namespace -package mypackage.test - --- Include external script files -include "common.fk" - --- Struct definition -struct User - id - name - extra -end - --- Constants -const MAX_COUNT = 100 -const DEFAULT_NAME = "Guest" -const CONFIG_MAP = {1 : "Alpha" 2 : "Beta"} - --- Function definition -function process_user(arg1, arg2) - - -- Calling bound Java static functions - local sum = MathUtils.add(arg1, 10) - - -- Conditional statements - if arg1 < arg2 then - -- Spawn a lightweight coroutine - fake background_task(arg1, arg2) - elseif arg1 == arg2 then - print("Values are equal") - else - print("arg1 is greater than arg2") - end - - -- For loop - for local i = 0, i < arg2, i++ do - print("Loop index: ", i) - end - - -- Dynamic Array - local arr = array() - arr[0] = 100 - arr[1] = 200 - - -- Dynamic Map - local m = map() - m["key"] = "value" - m[1] = arr - - -- Struct usage - local u = User() - u->id = 1001 - u->name = "Alice" - - -- Switch case - switch arg1 - case 1 then - print("case 1") - case "a" then - print("case a") - default - print("default") - end - - -- Return multiple values - return sum, m["key"] -end -``` +`lgc.c` is one of the most intricate parts of the C implementation: tri-colour +incremental marking, generational mode, write barriers, finalizers, weak tables. +All of it exists to do what the JVM already does — concurrently, and better tuned +than a hand-rolled collector written in Java would be. The file is deleted +outright. Only the *semantics that depend on collection happening* are rebuilt on +JVM primitives: ---- +| Lua concept | C mechanism | This implementation | +|---|---|---| +| Object lifetime | `lgc.c` tri-colour marking | **JVM GC** (G1 / ZGC) | +| Weak tables (`__mode = "k"/"v"/"kv"`) | weak links swept in `lgc.c` | `WeakReference` + `ReferenceQueue` | +| `__gc` finalizers | `luaC_checkfinalizer` / `GCTM` | `java.lang.ref.Cleaner` | +| Short-string interning | `lstring.c` table pinned against collection | weak intern pool; entries die when unreferenced | -## Java Integration Example +Everything else — lexer, parser, code generator, VM, metamethods, coroutines, +standard library — is a direct port. -### 1. Bind Java Methods -Annotate methods with `@fakescript`: +--- -```java -package com.example; +## Architecture + +The package layout mirrors the C sources one-to-one, so a reader holding +`lua-5.4.x` side by side can find their way around: + +| Lua 5.4 C source | Java | +|---|---| +| `lobject.h` / `lobject.c` | `LuaValue`, `LuaString`, `LuaTable`, `Proto`, `Closure`, `Upvalue` | +| `lstring.c` | `StringPool` | +| `ltable.c` | `LuaTable` | +| `lfunc.c` | `Proto`, `Closure`, `Upvalue` | +| `lstate.c` | `LuaState`, `CallInfo`, `GlobalState` | +| `lzio.c` | `Zio` | +| `llex.c` | `Lexer` | +| `lparser.c` | `Parser` (hand-written recursive descent, as upstream) | +| `lcode.c` / `lopcodes.h` | `FuncState`, `Codegen`, `OpCode` | +| `lvm.c` | `Interpreter` | +| `ldo.c` | call frames, protected calls, error propagation | +| `ltm.c` | `Meta` (metamethod dispatch) | +| `ldebug.c` | `Debug`, error messages, stack traces | +| `lapi.c` / `lauxlib.c` | operations on `LuaState`, `AuxLib` | +| `lundump.c` / `ldump.c` | bytecode load / dump | +| `lbaselib.c`, `lcorolib.c`, `loadlib.c`, `lstrlib.c`, `ltablib.c`, `lmathlib.c`, `liolib.c`, `loslib.c`, `lutf8lib.c`, `ldblib.c` | corresponding `lib.*` classes | +| `lgc.c` | **absent** — see above | + +The auxiliary layer (`lauxlib.c` and friends) comes along, because the standard +library is written against it. -import com.github.esrrhs.fakescript.fakescript; +--- -public class MathUtils { - @fakescript - public static int add(int a, int b) { - return a + b; - } -} -``` +## Key Design Decisions -### 2. Execute Script in Java +These are the places where translating C to Java is not mechanical, and where a +wrong call costs correctness that is expensive to recover later. -```java -import com.github.esrrhs.fakescript.fake; -import com.github.esrrhs.fakescript.fk; -import com.github.esrrhs.fakescript.fkconfig; - -public class Main { - public static void main(String[] args) throws Exception { - // 1. Initialize environment - fake f = fk.newfake(new fkconfig()); - fk.openbaselib(f); - - // 2. Register Java classes or packages - fk.regclass(f, MathUtils.class); - - // 3. Parse script code or file - String script = - "function calc(x, y)\n" + - " return MathUtils.add(x, y) * 2\n" + - "end\n"; - fk.parsestr(f, script); - - // 4. Run script function - Object result = fk.run(f, "calc", 10, 20); - System.out.println("Result: " + result); // Output: 60.0 - } -} -``` +### 1. Lua strings are byte strings, so Java `String` cannot be used ---- +A Lua string may contain `\0`; `#s` counts **bytes**; `s:byte(i)` returns a byte. +Java `String` is UTF-16 and rejects lone surrogates. Any real-world Lua project +that touches binary data, UTF-8 text, or embedded `\0` will break if strings are +backed by `String`. Lua strings are therefore backed by `byte[]`, and every string +library function is implemented byte-wise. -## Installation +### 2. Values keep the integer/float subtype split -### Maven +Lua 5.4 distinguishes `1` (integer) from `1.0` (float): they compare equal, but +`math.type` differs, `//` differs from `/`, `1/2` is `0.5` while `1//2` is `0`, +and coercion to string yields `1` vs `1.0`. Values are a **mutable slot** type +(a `type` tag plus `long`, `double` and an `Object` payload) mirroring C's `TValue` +— this avoids boxing and lets the VM write stack slots in place. -Add the dependency to your `pom.xml`: +### 3. Tables keep the array part / hash part split -```xml - - com.github.esrrhs - fakescript-java - 1.0.16 - -``` +Ported from `ltable.c`, including the migration logic that decides whether an +integer key is dense enough to live in the array part. Integer keys and string keys +are distinct entries: `t[1]` and `t["1"]` are different, as in Lua. -### Gradle +### 4. Coroutines run on virtual threads -```groovy -implementation 'com.github.esrrhs:fakescript-java:1.0.16' -``` +Lua coroutines can yield from arbitrarily deep stacks — inside `pcall`, inside a +metamethod, inside a `for` iterator. Reproducing that with an explicit state +machine is the hardest part of rewriting `lvm.c`. Instead, each Lua coroutine runs +on a Java **virtual thread**: `coroutine.yield` parks it, `resume` unparks it. +Because Lua functions are executed by the interpreter on that same thread, yields +at any depth fall out naturally, and virtual threads are cheap enough to run +thousands of coroutines. This is why Java 21 is the floor. ---- +The coroutine layer sits behind an interface so a state-machine implementation can +replace it later without touching callers. -## Profiling +### 5. Errors use Java exceptions, not `setjmp` / `longjmp` -Built-in per-function profiler: +`lua_error` becomes a thrown error carrying the Lua error value. `pcall` / `xpcall` +catch it, as does the coroutine boundary. Care is needed so that non-string error +values, error objects carrying `__tostring`, and errors crossing a coroutine +boundary all behave as upstream does. -```java -fk.openprofile(f); -fk.run(f, "main"); -fk.closeprofile(f); -System.out.println(fk.dumpprofile(f)); // calls, total & per-call time per function -``` +### 6. No JFlex / Bison ---- +The Lua reference parser is hand-written recursive descent. Porting it directly +removes the build-time code-generation step, along with the generated-parser drift +problem the previous architecture had. -## Language Notes +### 7. Metamethods: all of them, including the awkward rules -* String concatenation uses `..` (Lua style): `"key" .. 1`. The `+` operator is arithmetic only. -* Multi-return declaration assignment is `a, b := f()`; `a, b = f()` assigns to pre-declared variables. -* Sleeping coroutines do not busy-wait: `fk.run` sleeps until the nearest wake-up point. -* Keywords follow Lua 5.4: `local`, `function`, `and` / `or` / `not`, `~=` (not equal), `#t` (length, same as `size(t)`). -* Loops end with `do` (`while ... do ... end`, `for ... do ... end`); `if` / `elseif` still take `then`. -* Lua-style numeric `for i = 1, n[, step] do ... end` (step defaults to 1) is **inclusive** on both ends. The pre-existing `for local i = a -> b, step do` is **half-open** (`b` excluded) — do not mix the two forms. -* Table constructors work at runtime: `local t = {1, 2, 3}` (array, 0-based) and `local m = {a = 1, b = 2}` (map), plus `{}` for an empty array.

-**排序建议**：D13 运行时表构造先于 D11。`const` 版本已有 AST 与求值路径（`explicit_value_node` 的 `EVT_MAP`/`EVT_ARRAY`），复用到运行期比从零做比较值更稳，也先享受 Stage A 的成果。 - -> **D13 落地形态（回填）**： -> ``` -> table_constructor : '{' '}' | '{' table_array_list '}' | '{' table_map_list '}' -> table_array_list : expr_value | table_array_list ',' expr_value -> table_map_list : IDENTIFIER '=' expr_value | table_map_list ',' IDENTIFIER '=' expr_value -> ``` -> `table_constructor` 同时挂在 **`expr_value` 和 `expr`** 两个非终极符下（只挂前者够不到 -> `local t = {1,2}`，见开头回填的第 1 条）。编译期在 `compile_table_constructor` 里脱糖成 -> 临时变量 `__fktable_N` + `array()`/`map()` 调用 + 逐元素 `container_get` 赋值， -> 最后把临时变量作为表达式的值 —— **没有新增 opcode**，与原方案「L2 需构造 opcode」的预估不同， -> 这也说明"复用现有节点/指令"这条路比想象中宽。 -> -> 支持范围（有测试锁定）：`{1,2,3}`、`{a=1,b=2}`、`{}`、元素为表达式或函数调用、嵌套 -> （`{1,{2,3}}` 经临时变量取内层）、作实参（`size({1,2,3})`）、循环内构造。 -> **不支持**（干净地 PARSE_FAIL，有用例锁定）：`{["a"]=1}` 表达式键、`{a=1, 2}` 混合键、 -> `t[1][0]` 链式下标（既有限制，与 D13 无关）。 -> 冲突数 59 → **69**（+10，全 shift/reduce，0 reduce/reduce）。 - -### 已知分歧：数值 for 的两处与 Lua 不一致（尚未修） - -给 D10/D13 补 fuzz oracle 时顺手探出来的。**都不是 D10 引入的** —— 既有的 `->` -与 C 式写法同样如此，只是 Lua 化之后会有更多人照 Lua 的直觉来用，从而踩到： - -| # | 写法 | Lua 5.4 | 本实现 | 严重度 | -|---|---|---|---|---| -| 1 | `for i = a, b, 0 do`（且 `a >= b`） | 报 `'for' step is zero` | **死循环**，跑满 `max_run_cmd_num`（1 亿条指令）才被掐断 | **高** | -| 2 | `for i = 1, n do ... n = 100 ... end` | 边界只求值一次，跑 3 次得 6 | `m_end` / `m_add` 每轮重新求值，一路跑到 100 得 5050 | 中 | - -第 1 条的成因：`interpreter` 的 FORBEGIN 只在 `add > 0` 时才用 `<=` 判越界， -否则走 `>=` 分支；步长 0 落到后者，`a >= b` 时不跳转 → 进循环体 → `i += 0` 恒不变 -→ 永远满足继续条件。嵌入式场景里这是实打实的拒绝服务面（宿主脚本卡死）。 - -第 2 条的成因：`compiler.compile_for_loop_stmt` 把 `m_end` / `m_add` **编译了两次** -（循环头一次、`continuepos` 处一次）。对 C 式 `for local i = 0, i < n, i++ do` -来说条件必须每轮求值，这是刻意设计；但 Lua 形态要求只求值一次。 - -两处都由 `LuaSyntaxTest` 里的 `testZeroStepIsNotRejected` 与 -`testForBoundsAreReevaluatedEachIteration` 钉住当前行为。 -**注意第 1 条只钉了 `a < b` 那个方向**（静默 0 次迭代）——`a >= b` 的方向故意不写成 -用例，它会跑满一亿条指令把套件拖垮。 - -修法待定： -- 第 1 条可以在 FORBEGIN 里加「步长为 0 直接报错」，但那是行为变更 - （原本静默 0 次迭代的 `a < b` 情形会开始报错），需要确认是否接受 -- 第 2 条若只改 Lua 形态（把边界提到隐藏临时变量里）则不影响既有写法， - 代价是 for 的 codegen 要分两条路 - -### Stage D —— 架构级（本方案只列不落地） -D16 一等函数与闭包、D14 泛型 for、D15 变长参数、D17 metatable、D18 协程 - -其中 D16 是分水岭：没有 upvalue 机制，闭包无从谈起；而一旦引入，函数调用、栈帧、常量池都要动。建议作为独立项目评估，不要搭在「语法对齐」的车上。 - ---- - -## 4. 每个 Stage 的验证方法（必须先落地再往前走） - -1. **冲突数可度量**：基线 **57 shift/reduce、0 reduce/reduce**（`%expect 57` 恰好被满足）， - 现为 **69**（Stage A +1、D10 +1、D13 +10）。每个 Stage 记录 delta；出现任何 reduce/reduce - 都要给出书面理由，不接受「bison 自己会选」 -2. **生成文件同步**：`YYParser.java` 只能由 bison 重生成并提交，**禁止手改**。CI 的 `Grammar regeneration` job 就是这道闸 -3. **回归测试**：全量 `./mvnw clean test` 绿 + JaCoCo 行覆盖门禁 0.85 -4. **新增用例**：每条差异项至少 1 个正向用例 + 1 个「旧写法仍可用」的保兼容性用例，集中放进 `EdgeCaseTest` -5. **反向变异验证**：新增测试必须证明自己有牙齿——把改动故意改坏，测试要能报错。上一轮用这套做法验证了 4 个差分 oracle，各自在最早用例就失败；同一轮里它也反过来证明「比较作值」在语义上根本跑不通。测不出来问题的新测试不如不写 -6. **CI 7/7 全绿**：含 `Fuzzing (Jazzer)` 与 `Grammar regeneration` - ---- - -## 5. 红线 - -- **每个 Stage 一个 PR**，独立可回滚；禁止一个 PR 同时动词法与 opcode -- **只增不改**：不删除任何现行写法（第 1.3 节原则） -- **不手改 `YYParser.java`** -- **数值语义不得回退**：`LuaNumberSemanticTest` 是红线集合，任何一条挂掉就停下 -- **文档同步**：README / README_CN 的语法说明与「fakescript 扩展语法」章节同步更新，明确哪些是 Lua 兼容哪些是本语言扩展 - ---- - -## 6. 建议的推进顺序 - -| 顺序 | 内容 | 预估量级 | 建议 | -|---|---|---|---| -| 1 | Stage A 全部 | 小 | **立即做**，性价比最高 | -| 2 | Stage B 的 D10 数值 for | 小–中 | **已完成** | -| 3 | Stage C 的 D13 运行时表构造 | 中 | **已完成**（实际为 L1 脱糖，量级比预估小） | -| 4 | Stage C 的 D11 比较作值 + D12 布尔 | 中–大 | 下一步；先就「真假值表示」达成一致 | -| 5 | Stage B 的 D8 全局赋值 | 中 | **先出语义说明**，再决定 | -| 6 | Stage D | 大 | 单独立项 | - -第一步落地前需要确认两点：是否接受「`local`/`function`/`do` 走别名」这种加法路线（而非替换），以及 Stage A 是否一次性全做完还是拆六个 PR。 -（**已确认**：走替换路线且 Stage A 一次性做完，见开头纪要。） diff --git a/jflexbison/YYParser.y b/jflexbison/YYParser.y deleted file mode 100644 index 995bc0b..0000000 --- a/jflexbison/YYParser.y +++ /dev/null @@ -1,2007 +0,0 @@ -%{ -package com.github.esrrhs.fakescript; -

- * 为什么必须单独建一套：这两条语法是本项目里最年轻的代码，且都属于 - * 「不崩但算错」的高危类型——数值 for 错一格就是静默少跑一次，表构造错一格 - * 就是静默构造出另一个容器。而已有的表达式/标准库 oracle 一条都覆盖不到它们 - * （表达式生成器只产算术 AST，标准库生成器只从 array()/map() 起步）。 - * 换句话说：语法越新，越不能指望老 oracle 顺手兜住。 - *

- * 两种 oracle 思路： - *

    - *
  1. 数值 for —— Java 参考模型。Lua 5.4 的语义是 begin/end/step - * 在循环开始前各求值一次，步长正时 i <= end、为负时 - * i >= end。模型按这个规则独立算一遍迭代序列。
    2. - *
  2. 表构造 —— 脱糖不变式。{1,2,3} 与它脱糖后的 - * array(); t[0]=1; ... 必须逐字节相同。参考实现就是既有 - * 的显式构造路径，因此这条 oracle 不需要自己维护容器模型。

So a value sitting in a register *above* `top` is invisible to + the collector, and gets collected. Two shapes depend on this: a value pushed + by a C function such as `next` (the call returns, `top` drops back, the slot + still holds the key), and the table built by the last iteration of a loop + (`for i = 1, 5 do t[i] = {i} end` leaves `{5}` in a register while `L->top` + only reaches the call's arguments). Our `stack` is a Java array, so **every + slot is a live reference** — `LuaState.clearDeadStackSlices` reproduces that + clearance, and has to run *inside* `collectgarbage`, not on every `top` + change (see the next bullet). +* **…but clearing eagerly on every `top` change breaks two things.** C only + clears during the atomic phase. Doing it inline silently destroyed both + `luaT_callTMres`'s result (the destination register can *be* the slot being + popped) and the error object of `pcall` (`LuaError.value` aliases a live stack + slot, because `error('boom', 0)` throws `L.arg(0)` itself — so `pcall` started + returning `false nil`). Waiting until `collectgarbage` is both faithful and + exactly as precise. +* **A weak table's storage has to *be* weak, not merely carry a `WeakReference` + beside it.** The payload in the slot is the `WeakReference`; a strong payload + means nothing is ever released. That has a consequence: `LuaTable.get` must + hand back a *copy* for weak tables, so the write fast path + (`OP_SETTABLE`'s "slot found, write into it") cannot be used on them — + writing into a copy is a no-op, and `t.f = g` would leave `t.f` equal to `f`. +* **`__mode` is read dynamically, and re-wraps everything that is already in the + table.** Building a table, filling it, and *then* calling + `setmetatable(t, {__mode = 'k'})` still lets those entries be collected — + measured. Since our weakness is a storage form, changing the mode has to walk + the table and re-wrap in place, and a weak table must keep everything in the + hash part (array slots are plain `LuaValue`s and cannot hold a `WeakRef`). +* **`__gc` needs the object *alive*, which no JVM reference type can give you.** + Every "it's dead" notification (`WeakReference` cleared, `Cleaner`, + `PhantomReference`) arrives after the object is unreachable, and the reference + cannot be recovered. Only `finalize()` runs while `this` is still usable, and + it is allowed to *resurrect*. So a table with `__gc` gets a sentinel that only + it points to; when both go unreachable the sentinel's `finalize` pushes the + table onto a pending queue, and the next `collectgarbage` drains that queue on + the **Lua thread** — never on the JVM finalizer thread, where calling into a + `LuaState` would race and any exception would vanish without a trace. + +### Three known divergences from the reference + +These are not oversights; each is a place where the JVM has no primitive to +match, and each is documented rather than papered over. + +* **Ephemeron tables only handle the case where the value *is* the key.** + `__mode='k'` with `t[k] = k` clears the entry (matching the reference), and + the usual cache shape `cache[obj] = {fresh data}` keeps its value (also + matching). But `t[k] = {k}` — value *contains* key, key otherwise + unreachable — keeps the entry where Lua would drop it.

Runtime-only comparison would let "the + compiler emits something slightly wrong that still happens to run" through; + the artefact comparison pins down constant ordering, the line tables, local + and upvalue debug info, and `maxstacksize` as well. + +Eight shapes are checked that way — plain, nested, vararg, upvalue, `goto`, +loop, assorted constants, and a constant string longer than +`LUAI_MAXSHORTLEN` (which takes the non-interned long-string path on both the +dump and the undump side). + +#### Six things the reference binary settled in Phase 8 + +* **`luaU_undump` rewrites the chunk name before it ever reports an error.** + A leading `@` or `=` is dropped; a name that starts with the signature byte + (i.e. the chunk name *is* the binary chunk, which is what `load(s)` uses when + no second argument is given) becomes the literal `binary string`. So + `load("\27Lua")` reports `binary string: bad binary format (truncated + chunk)` — not an ESC-prefixed mess. +* **`f_parser` consumes the first byte on the binary path but hands it back on + the text path.** `luaU_undump`'s comment says so directly: "skip 1st char + (already read and checked)". Ungetting it before `undump` misaligns the whole + header by one byte and turns `truncated chunk` into + `not a binary chunk`. +* **`luaO_chunkid` has a third form, and it is the one `load` hits.** Only + `@x` and `=x` are stripped; anything else is wrapped as `[string "x"]`. + `load("x++")` reports `[string "x++"]:1: syntax error near '+'` — a + "strip the prefix" implementation that skips the wrapping reports `x++:1:`, + and every load-time error message is then wrong. +* **Chunk names are byte strings, and `luaO_chunkid` truncates by bytes.** + Decoding to a Java `String` first and truncating there gets the length wrong + on non-UTF-8 names. `chunkId` therefore has a `byte[]` core and the `String` + overload goes through it. +* **A prototype with no source gets *no* position at all — not even a line + number.** `luaG_addinfo` is `if (src) ... else return msg`. This is + observable: `string.dump(f, true)` strips the source, so + `pcall(load(string.dump(f, true)))` reports the bare `boom`. Falling back to + the chunk name not only adds a prefix, it splices the raw binary chunk into + the message (invalid UTF-8, so it decodes to replacement characters). +* **`lundump`'s `default: lua_assert(0)` is a no-op.** `lua_assert` compiles to + `((void)0)` in a default build, so a chunk whose constant type byte is `99` + loads fine and that constant is just `nil`. Raising an error there is + inventing a semantic of our own. Measured, not assumed: the hand-built chunk + loads as a `function` on the reference. + +One more, on the dump side: `dumpFunction` compares sources **by reference** +(`f->source == psource`), not by content.

Without it, + `debug.sethook(f, "l")` produces zero line events. +* **A hook error is *not* caught by the `pcall` it is reported for.** The `call` + hook for `pcall` fires inside `precallC`, *before* `pcall` establishes its + recovery point, so `pcall(function() ... end)` cannot catch an error raised by + a `call` hook on `pcall` itself. +* **`CIST_HOOKED` is tested before `isLua`** in `funcnamefromcall`. The frame + carrying the mark is often a **C** frame (the `call` hook for `pcall` is + reported on `pcall`'s own C frame), so testing `isLua` first never reaches it + — and the traceback line changes from `in hook '?'` to + `in function `. +* **Hooks can never yield.** `hookf` calls the user function with `lua_call`, + which goes through `luaD_callnoyield`, so the non-yieldable counter is non-zero + inside a hook. Measured: `coroutine.yield()` in a hook reports `attempt to + yield from outside a coroutine` on the main thread and `attempt to yield + across a C-call boundary` in a coroutine — in both cases the program or + coroutine dies. This is why the port does not implement `CIST_HOOKYIELD` at + all: it is unreachable from Lua. (`CIST_HOOKYIELD` exists upstream for *C* + hooks installed via the C API, which are called directly rather than through + `lua_call`.) + +#### One ordering bug found by the hook gate + +`allowhook` must be restored at the **protected-call boundary**, *after* the +message handler has run — not before. The handler runs at the throw point, where +`allowhook` is still 0 (that is what stops a traceback from re-entering the +hook). Restoring it earlier means the traceback triggers the hook again, which +raises again, which `applyErrMsg` turns into `error in error handling`. The +symptom: `debug.sethook(function() error("x") end, "c")` followed by an uncaught +error printed `error in error handling` instead of a real traceback. + +#### Five things the reference binary settled in Phase 9 + +* **Level 0 is the C frame of `getinfo` itself.** `lua_getstack(L, 0, &ar)` + succeeds and yields `what = "C", currentline = -1, name = "getinfo"`. The name + comes from `funcnamefromcall` reading the *caller's* frame, so it answers "what + was the caller calling", not "what is this frame called". Getting this off by + one shifts every `debug.getinfo(n)` result by a level. +* **`'f'` and `'L'` need `lua_rotate`, not a pop.** The result table is pushed + *after* `lua_getinfo`, so `lua_getinfo`'s own outputs sit *underneath* it. + `treatstackoption` is `lua_rotate(L, -2, 1)` followed by `lua_setfield(L, -2)`. + Doing `L.top--` instead pops the result table itself — the symptom is + `debug.getinfo(1)` returning something that prints as a function, and + `debug.getinfo(1).func` holding the table. +* **`pushfuncname` tries a *global* name first.** `error` is `global 'error'` as + far as `getobjname` is concerned (it is a `GETTABUP _ENV`), but a traceback + prints `function 'error'` — `pushglobalfuncname` looks the function up **by + value** in `_LOADED._G` and wins. Checking only `ar.namewhat` gets the + qualifier wrong on every C function that has a global name. +* **The message handler runs *before* the stack unwinds** — `luaG_errormsg` + calls it at the throw point, not from `luaD_pcall`'s recovery. This is the whole + reason `xpcall(f, debug.traceback)` shows the full traceback instead of just the + outer two frames. Java has no `longjmp`, but the *Lua* stack (`stack` / `top` / + `ci`) is still intact at the `catch`, so running the handler at the top of + `pcall`'s catch is equivalent. +* **`LEVELS1` / `LEVELS2` are 10 and 11**, not a round 10/10, and the head and + tail are *not* the same length. The "(skipping N levels)" count is off by one + otherwise, and only on stacks deep enough to trigger it. + +#### Two bugs found by the `debug` gate, neither of them in `debug` + +* **`OP_TESTSET`'s condition was inverted, which broke `and` / `or`.** Upstream + tests `l_isfalse(rb) == k`; this port tested `toBoolean() == (k != 0)` — and + those two are exact opposites over `k`'s two values. It is a *quiet* bug: + `TESTSET` only survives when the result register differs from `B` + (`patchTestReg` rewrites it to `OP_TEST` otherwise), so `if x then` was always + right while `x and y` was always wrong. The symptom is + `print(t and "yes")` printing the table, and — worse — `cond and a or b`, + the most common idiom in Lua, taking the wrong branch. **The bytecode gate + could not see it**: the emitted code was field-for-field identical to the + reference's. `RuntimeTest.logicalOperatorsReturnValues` now pins the returned + value, not just the truthiness. +* **`xpcall`'s handler ran after the call chain had already been restored.** + See the fourth bullet above; `xpcall(f, debug.traceback)`'s traceback was two + frames long instead of seven. + +#### One thing the reference binary settled that is a *driver* difference + +`lua.c` runs the script from inside `pmain`, a **C function**, so an extra C +frame sits under the main chunk. It shows up as the trailing `[C]: in ?` in every +traceback and as `debug.getinfo(3).what == "C"`. A host that calls +`luaL_dostring` directly has no such frame and sees neither. This is therefore +fixed in the differential driver (`Diff` now mirrors `lua.c`: `pmain` + +`docall` + `msghandler`), not in the engine — bending the engine to match would +have made `luaL_dostring` wrong instead. + ### What is still missing -* **The whole `debug` library.** `debug` is currently `nil`. It needs `ldebug.c` - (`getinfo`, locals, upvalues, hooks) as well as `ldblib.c`. +Nothing in the language or the ten standard libraries.

`settraps` 做的。 + 少了它，`debug.sethook(f, "l")` 一个行事件都不会来。 +* **钩子里的错误，不会被它所报告的那个 `pcall` 抓住。** `pcall` 的 `call` + 钩子是在 `precallC` 里、在 `pcall` 建好恢复点之前报的，所以 + `pcall(function() ... end)` 抓不到「钩子在 `pcall` 自己身上抛的错」。 +* **`funcnamefromcall` 里 `CIST_HOOKED` 要判在 `isLua` 之前。** 带这个标记 + 的那一帧常常是 C 帧（`pcall` 的调用钩子就打在 `pcall` 自己的 C 帧上）， + 先判 `isLua` 永远走不到这一支——回溯里那一行会从 `in hook '?'` 变成 + `in function <文件:行>`。 +* **钩子永远不能 yield。** `hookf` 用 `lua_call` 调用户函数，而 `lua_call` 走 + `luaD_callnoyield`，「不可 yield」的层数在钩子里非零。实测：钩子里 + `coroutine.yield()` 在主线程上报 `attempt to yield from outside a coroutine`、 + 在协程里报 `attempt to yield across a C-call boundary`，两种情况都让程序/协程 + 死掉。这就是为什么本实现根本没搬 `CIST_HOOKYIELD`——从 Lua 里走不到 + （上游那个标记是给「由 C API 直接装的 C 钩子」用的，那种钩子不走 `lua_call`）。 + +#### 由钩子这道闸门抓出来的一个顺序 bug + +`allowhook` 必须在保护调用边界上恢复，而且是在消息处理函数跑完之后， +不是在它之前。处理函数是在抛出点跑的，那时 `allowhook` 还是 0（正是这一点让回溯 +不会重新进钩子）。提前恢复成 1，回溯就会再触发一次钩子、再抛一次错，最后被 +`applyErrMsg` 兜成 `error in error handling`。症状是 +`debug.sethook(function() error("x") end, "c")` 之后那个未捕获错误打出来的是 +`error in error handling`，而不是真正的回溯。 + +#### 阶段 9 里由参考实现裁定的五件事 + +* **层号 0 是 `getinfo` 自己的 C 帧。** `lua_getstack(L, 0, &ar)` 会成功， + 给出 `what = "C", currentline = -1, name = "getinfo"`。名字来自 + `funcnamefromcall` 读调用者那一帧，所以它回答的是「调用者当时在调谁」， + 不是「这一帧叫什么」。搞错一处，所有 `debug.getinfo(n)` 整体错一层。 +* **`'f'` 与 `'L'` 要 `lua_rotate`，不能弹。** 结果表是 `lua_getinfo` 之后 + 才压的，所以 `lua_getinfo` 自己的产物在它底下。 + `treatstackoption` 是 `lua_rotate(L, -2, 1)` 再 `lua_setfield(L, -2)`。 + 写成 `L.top--` 弹掉的是结果表本人——症状是 `debug.getinfo(1)` 返回一个 + 打印出来像函数的东西，而 `debug.getinfo(1).func` 里存着那张表。 +* **`pushfuncname` 先试全局名。** `error` 在 `getobjname` 眼里是 + `global 'error'`（一条 `GETTABUP _ENV`），但回溯打的是 `function 'error'`—— + `pushglobalfuncname` 在 `_LOADED._G` 里按值反查到了它，并且优先。 + 只看 `ar.namewhat`，每个有全局名的 C 函数的修饰语都会错。 +* **消息处理函数在栈还没退的时候跑** —— `luaG_errormsg` 是在抛出点调它的， + 不是在 `luaD_pcall` 的恢复里。这就是 `xpcall(f, debug.traceback)` 能打出完整 + 回溯、而不是只剩最外面两层的原因。Java 没有 `longjmp`，但 `catch` 到的那一刻 + Lua 栈（`stack` / `top` / `ci`）还是完好的，所以把处理函数放在 + `pcall` 的 `catch` 最前面跑是等价的。 +* **`LEVELS1` / `LEVELS2` 是 10 和 11**，不是整整齐齐的 10/10，头尾也不等长。 + 否则「(skipping N levels)」那个数差 1——而且只在深到会触发它的栈上才暴露。 + +#### 由 `debug` 这道闸门抓出来的两个 bug，都不在 `debug` 里 + +* **`OP_TESTSET` 的判条件写反了，于是 `and` / `or` 是错的。** 上游判 + `l_isfalse(rb) == k`，这里判成了 `toBoolean() == (k != 0)`——这两者在 `k` + 的两个取值上恰好相反。它静默：`TESTSET` 只在「结果寄存器 ≠ B」时才 + 保留下来（`patchTestReg` 否则把它改写成 `OP_TEST`），于是 + `if x then` 一直是对的，`x and y` 一直是错的。症状是 + `print(t and "yes")` 打印出那张表；更糟的是 `cond and a or b`——Lua 里最常用的 + 惯用法——整体取错分支。**字节码闸门看不见它**：两边的字节码逐字段相同。 + `RuntimeTest.logicalOperatorsReturnValues` 现在钉住的是返回的哪个值， + 不只是真假。 +* **`xpcall` 的处理函数跑在调用链已经恢复之后。** 见上面第四条： + `xpcall(f, debug.traceback)` 的回溯只有两层，应该是七层。 + +#### 一处由参考实现裁出来、但属于「驱动方式」而不属于引擎的差异 +
