From 98ad50c66f9d46eed876eb07d6b4ac3548cae7da Mon Sep 17 00:00:00 2001 From: Claude Date: Wed, 3 Jun 2026 21:35:52 +0000 Subject: [PATCH 01/10] fix(krl): accept bare `=` in lexer and export AST surface Two incomplete-refactor bugs blocked the KRL parser test suite: 1. Lexer shadowing. A strict `=` handler threw `KRLLexError` on bare `=` and shadowed a later, unreachable block that correctly emitted `:eq` for `=` and `:fat_arrow` for `=>`. Every `let x = ...` and `filter ... = ...` program, plus the `=>` operator, failed to lex. Merge into one reachable block: `==` and bare `=` map to `:eq`, `=>` to `:fat_arrow`. The lexer records the glyph only; binding-vs- comparison is resolved by the parser/typechecker, not refused lexically. 2. Unexported AST surface. Ast.jl exported only the abstract node types, so any consumer referencing concrete types (KRLProgram, KRLCompare, KRLFilterStage, ...) hit UndefVarError. Export the full public AST surface and switch the parser/SQL tests to `using .KRL`. Adds a bare-`=` regression (let binding + filter equality) and the `("=", :eq)` lexer case; removes the now-incorrect assertion that bare `=` throws. https://claude.ai/code/session_017TXizM5c1Yd9HWf7Y15YH2 --- server/krl/Ast.jl | 27 ++++++++++++++++++++++++++- server/krl/Lexer.jl | 19 ++++++++++--------- server/krl/test/lexer_test.jl | 4 +--- server/krl/test/parser_test.jl | 20 +++++++++++++++++++- server/krl/test/sql_test.jl | 2 +- 5 files changed, 57 insertions(+), 15 deletions(-) diff --git a/server/krl/Ast.jl b/server/krl/Ast.jl index a7b3112..89ced4e 100644 --- a/server/krl/Ast.jl +++ b/server/krl/Ast.jl @@ -30,7 +30,32 @@ Invariants (checked by the parser, not the AST constructors): """ export KRLNode, KRLStatement, KRLSource, KRLPipeStage, KRLReturnItem, - KRLExpr, KRLPatternNode, KRLType + KRLExpr, KRLPatternNode, KRLType, + # enums + values + ConfidenceLevel, ConfExact, ConfSufficient, ConfNecessary, ConfHeuristic, + SortOrder, SortAsc, SortDesc, + EdgeDir, EdgeForward, EdgeBackward, EdgeUndirected, + # program + statements + KRLProgram, KRLQueryStmt, KRLLetStmt, KRLRuleDef, KRLAxiomDef, + # query + sources + KRLQuery, KRLSourceKnots, KRLSourceDiagrams, KRLSourceInvariants, + KRLSourceNamed, KRLSourceSubquery, + # pipeline stages + KRLFilterStage, KRLSortStage, KRLTakeStage, KRLSkipStage, KRLReturnStage, + KRLGroupByStage, KRLAggregateItem, KRLAggregateStage, KRLFindEquivStage, + KRLFindPathStage, KRLMatchStage, KRLLetStage, KRLWithStage, + # return items + KRLReturnExpr, KRLReturnStar, KRLReturnEquivs, KRLReturnEquivClass, + KRLReturnProof, + # expressions + KRLNullCoalesce, KRLOr, KRLAnd, KRLNot, KRLCompare, KRLBinOp, KRLUnaryNeg, + KRLFieldAccess, KRLCall, KRLIndex, KRLVar, KRLKnotName, KRLInt, KRLFloat, + KRLString, KRLBool, KRLNone, KRLArray, KRLRecord, KRLGaussCode, KRLTypeAnn, + # graph patterns + KRLNodePattern, KRLEdgePattern, KRLGraphPattern, + # type annotations + KRLTyScalar, KRLTyOption, KRLTyList, KRLTySet, KRLTyResultSet, KRLTyEquiv, + KRLTyEquivConf, KRLTyMap, KRLTyTuple, KRLTyNamed # ─── Confidence level ──────────────────────────────────────────────────────── diff --git a/server/krl/Lexer.jl b/server/krl/Lexer.jl index 4eb1f7d..550beac 100644 --- a/server/krl/Lexer.jl +++ b/server/krl/Lexer.jl @@ -15,7 +15,7 @@ Token kinds (Symbol tags): :knot_name — `3_1`, `10_139` (digit `_` digit form) Names: :keyword — reserved word :identifier — user name or invariant name - Operators: :eq (`==`) + Operators: :eq (`==` or bare `=` — see `=` handling below) :neq (`!=`) :lt (`<`) :lte (`<=`) @@ -274,10 +274,17 @@ function tokenise(src::String)::Vector{Token} # ── two-character and single-character operators ────────────────────── if c == '=' + # KRL accepts bare `=` as surface syntax for let-bindings and + # filter equality (grammar.ebnf v0.1.0: `let id = expr`, + # `filter ... = value`).

The lexer fix itself is confirmed working by CI (KRL Lexer 246/246; KRL Parser went from a full failure to 160 passing with only these six pre-existing issues remaining). Parser bug (root): - find_path: `~>` is both the find_path separator and a comparison operator (_CMP_KINDS), so `_parse_expr` absorbed `src ~> tgt` into a single KRLCompare and the `~>` / `via` separators were lost. Parse find_path operands at additive level (below comparison). Stale / invalid tests (brought in sync with the spec-correct parser): - "Expression: function call" used `gauss(...)`, a dedicated form (→ KRLGaussCode); switched to a generic `dist(...)` so it exercises KRLCall. - "Gauss code: valid" asserted KRLCall/.args; the parser produces KRLGaussCode/.codes per spec/type-system.md §5 [T-Gauss]. - determinism property fed `take n` (identifier), but `take` requires an integer literal (KRLTakeStage.n::Int); changed to `take 3`. CI infra: - Agda step now runs `agda --safe` from each proof file's own directory so the top-level module name matches the file name. https://claude.ai/code/session_017TXizM5c1Yd9HWf7Y15YH2 --- .github/workflows/krl-verification.yml | 4 +++- server/krl/Parser.jl | 8 ++++++-- server/krl/test/parser_test.jl | 17 ++++++++++------- 3 files changed, 19 insertions(+), 10 deletions(-) diff --git a/.github/workflows/krl-verification.yml b/.github/workflows/krl-verification.yml index 64ca821..9192198 100644 --- a/.github/workflows/krl-verification.yml +++ b/.github/workflows/krl-verification.yml @@ -80,7 +80,9 @@ jobs: found=0 for f in $(find verification/proofs/agda -name '*.agda' 2>/dev/null); do echo "── agda --safe $f" - LC_ALL=C.UTF-8 agda --safe "$f" + # Run from the file's own directory so the top-level module name + # (e.g. `DihedralQuandle`) matches the file name as Agda requires. + ( cd "$(dirname "$f")" && LC_ALL=C.UTF-8 agda --safe "$(basename "$f")" ) found=1 done if [ "$found" = "0" ]; then echo "No Agda proofs found"; exit 1; fi diff --git a/server/krl/Parser.jl b/server/krl/Parser.jl index e17da8f..cc430d4 100644 --- a/server/krl/Parser.jl +++ b/server/krl/Parser.jl @@ -488,9 +488,13 @@ end function _parse_find_path_stage(ps::ParserState)::KRLFindPathStage t = _expect!(ps, :keyword, "find_path") - src_e = _parse_expr(ps) + # `~>` is the find_path separator AND a comparison operator (_CMP_KINDS), + # so the operands must be parsed *below* the comparison level — otherwise + # `_parse_expr` greedily absorbs `src ~> tgt` into a single KRLCompare and + # the `~>`/`via` separators are lost.
