Performance: Regex processes ~1ms/file vs 50-200ms/file for ANTLR4/tree-sitter. + * On EPAGHE (14k COBOL files), this is ~14 seconds vs 12-47 minutes. + * + * 2. Reliability: tree-sitter-cobol@0.0.1's external scanner hangs indefinitely + * on ~5% of production files (no timeout possible). ANTLR4's proleap-cobol-parser + * is a Java project — using it from Node.js requires Java subprocesses or + * extracting .g4 grammars and generating JS/TS targets (significant effort). + * + * 3. Dialect compatibility: GnuCOBOL with Italian comments, patch markers in + * cols 1-6 (mzADD, estero, etc.), and vendor extensions. Formal grammars + * target COBOL-85 and would need dialect modifications. + * + * 4. Industry precedent: ctags, GitHub code navigation, and Sourcegraph all use + * regex-based extraction for code indexing. Full parsing is only needed for + * compilation or semantic analysis, not symbol extraction. + * + * 5. Determinism: Every regex pattern is tested with canonical COBOL input + * (see test/unit/cobol-preprocessor.test.ts). Same input always produces + * same output — no grammar ambiguity or parser state issues. + * + * This module provides: + * 1. preprocessCobolSource() — cleans patch markers (kept for potential future use) + * 2. extractCobolSymbolsWithRegex() — single-pass state machine COBOL extraction + */ + +// --------------------------------------------------------------------------- +// Public interfaces +// --------------------------------------------------------------------------- + +export interface CobolRegexResults { + programName: string | null;

IN/OF library-name now captured as metadata in CopyResolution (IN and OF are synonyms per COBOL-85 standard). Phase 2C: COPY REPLACING ==pseudotext== support. Tokenizer handles ==...== delimiters alongside "quoted" strings. Pseudotext forces EXACT type. Two-pass applyReplacing: first pass handles space-containing/ non-identifier pseudotext via global string replace; second pass handles identifier-level LEADING/TRAILING/EXACT. New test file cobol-copy-expander.test.ts with 10 tests. Phase 2E: PERFORM WS-COUNT TIMES no longer produces a false-positive perform target (checks for TIMES keyword after captured identifier). Phase 2F: Dynamic CALL via data item (CALL WS-PROG-NAME without quotes) now emits a CodeElement annotation node with description 'dynamic-call' instead of silently ignoring. Adds isQuoted:boolean to call results. Phase 3A: CICS MAP(WS-MAP-NAME) unquoted identifiers now captured. Phase 3B: Normalized || to ?? in copy-expander (done in Phase 1A). --- .../src/core/ingestion/cobol-processor.ts | 26 ++++++ .../ingestion/cobol/cobol-copy-expander.ts | 87 +++++++++++++------ .../ingestion/cobol/cobol-preprocessor.ts | 35 +++++--- .../test/unit/cobol-copy-expander.test.ts | 69 +++++++++++++++ gitnexus/test/unit/cobol-preprocessor.test.ts | 53 +++++++++++ 5 files changed, 234 insertions(+), 36 deletions(-) create mode 100644 gitnexus/test/unit/cobol-copy-expander.test.ts diff --git a/gitnexus/src/core/ingestion/cobol-processor.ts b/gitnexus/src/core/ingestion/cobol-processor.ts index abb4160e0b..3f4fe0ec52 100644 --- a/gitnexus/src/core/ingestion/cobol-processor.ts +++ b/gitnexus/src/core/ingestion/cobol-processor.ts @@ -441,6 +441,32 @@ function mapToGraph( // ── CALL -> CALLS relationship (cross-program) ────────────────── for (const call of extracted.calls) { + if (!call.isQuoted) { + // Dynamic CALL via data item — not statically resolvable. + // Emit a CodeElement annotation for visibility in impact analysis. + graph.addNode({ + id: generateId('CodeElement', `${filePath}:dynamic-call:${call.target}:L${call.line}`), + label: 'CodeElement', + properties: { + name: `CALL ${call.target}`, + filePath, + startLine: call.line, + endLine: call.line, + language: 'cobol' as any, + description: 'dynamic-call (target is a data item, not resolvable statically)', + }, + }); + graph.addRelationship({ + id: generateId('CONTAINS', `${parentId}->dynamic-call:${call.target}:L${call.line}`), + type: 'CONTAINS', + sourceId: parentId, + targetId: generateId('CodeElement', `${filePath}:dynamic-call:${call.target}:L${call.line}`), + confidence: 1.0, + reason: 'cobol-dynamic-call', + }); + continue; + } + const targetModuleId = moduleNodeIds.get(call.target.toUpperCase()); // Create edge even if target not yet known — use a synthetic target id const targetId = targetModuleId diff --git a/gitnexus/src/core/ingestion/cobol/cobol-copy-expander.ts b/gitnexus/src/core/ingestion/cobol/cobol-copy-expander.ts index 92b42c18cf..ac170cf5ab 100644 --- a/gitnexus/src/core/ingestion/cobol/cobol-copy-expander.ts +++ b/gitnexus/src/core/ingestion/cobol/cobol-copy-expander.ts @@ -31,6 +31,7 @@ export interface CopyResolution { resolvedPath: string | null; line: number; replacing: CopyReplacing[]; + library?: string; } export interface CopyExpansionResult { @@ -122,6 +123,7 @@ interface ParsedCopyStatement { endLine: number; target: string; replacing: CopyReplacing[]; + library?: string; } /** @@ -131,54 +133,67 @@ interface ParsedCopyStatement { * LEADING "ESP-" BY "LK-ESP-" LEADING "KPSESPL" BY "LK-KPSESPL" * "ANAZI-KEY" BY "LK-KEY" * TRAILING "-IN" BY "-OUT" + * ==CUST-== BY ==WS-CUST-== + * ==OLD-TEXT== BY ==== */ -function parseReplacingClause(text: string): CopyReplacing[] { +export function parseReplacingClause(text: string): CopyReplacing[] { const replacings: CopyReplacing[] = []; if (!text || text.trim().length === 0) return replacings; - // Tokenize: split on whitespace, preserving quoted strings - const tokens: string[] = []; - const tokenRe = /"([^"]*)"|(\S+)/g; + // Tokenize: ==pseudotext==, "quoted strings", or bare words. + // Pseudotext can contain spaces and single = chars but not ==. + interface TokenInfo { value: string; isPseudotext: boolean; } + const tokens: TokenInfo[] = []; + const tokenRe = /==((?:[^=]|=[^=])*)==|"([^"]*)"|(\S+)/g; let tm: RegExpExecArray | null; while ((tm = tokenRe.exec(text)) !== null) { - // Store the matched content; for quoted strings, keep the inner value - // but mark them so we can distinguish.

In free-format mode, lines are trimmed before processing, so data items like "01 WS-FIELD PIC X." have no leading whitespace after trimming. Changed to ^\s* (zero or more spaces) which works for both fixed-format (indented lines still have spaces) and free-format (trimmed lines).

charset=UTF-8 Content-Transfer-Encoding: 8bit Finding #2: Numeric sequence numbers now stripped (changed /[^0-9 ]/ to /\S/ in preprocessCobolSource). Lines like "000100 MAIN-PARAGRAPH." now have cols 1-6 blanked so paragraph regex matches correctly. Finding #11: JCL in-stream PROC ordering fixed — pre-register all PROCs into moduleNames before step processing. Steps that EXEC a PROC defined later in the same file now get CALLS edges. Finding #A: PROCEDURE DIVISION USING no longer captures calling-convention keywords (BY, VALUE, REFERENCE, CONTENT, ADDRESS, OF) as parameter names. Finding #C: SORT/MERGE USING/GIVING now captures ALL file references (multi-file), not just the first. Changed from single-match to section extraction with split.
