v2.37.0 — Graph Engine & Package Boundary Analysis

What's New

Graph Engine (pkg/graph/) — 1500 LOC, 11 tests

Package boundary analysis — check if your ABAP code stays within package boundaries:

SAP(action="analyze", params={
    "type": "check_boundaries",
    "package": "$ZDEV",
    "whitelist": "$ZCOMMON,$ZUTIL*"
})

Three modes: Offline (embedded parser, no SAP needed) | Object | Package

Dynamic call detection — catches CALL FUNCTION lv_variable, SUBMIT (lv_prog), CREATE OBJECT TYPE (lv_class) that CROSS/WBCROSSGT miss.

Six verdicts: STANDARD ✓ | SAME_PACKAGE ✓ | ALLOWED ✓ | VIOLATION ✗ | DYNAMIC ⚠ | UNKNOWN

Improved SAP Tool Description & Help

• Concise description with real SAP(action=..., target=..., params={...}) syntax
• Method-level read/edit: params={"method": "GET_DATA"}
• New SAP(action="help", target="tips") — best practices & workflows

Design Reports

• 001: GUI Debugger — 3-phase plan, ADT debugger API map
• 002: Graph Engine — ZXRAY port, 4 data sources, boundary queries
• 003: Codex Alignment — edge semantics, provenance model

Diagnostic Tips

# Verbose mode for all commands
vsp -v query T100
SAP_VERBOSE=true vsp search "ZCL_*"

# Different SAP versions have different endpoints
# If query fails but search works, your system may not support datapreview/freestyle

v2.33.0: CLI Verbose Fix

What's New in v2.33.0

Bug Fix: --verbose now works for all CLI subcommands

Previously --verbose / -v was a local flag only available in MCP server mode.
CLI subcommands like vsp query, vsp search, vsp source silently ignored it.

Fixed:

• vsp -v query T100 — now shows HTTP request/response details
• SAP_VERBOSE=true vsp query T100 — env var also works for CLI mode
• All subcommands inherit --verbose via PersistentFlags

How to Diagnose ADT Endpoint Issues

If a command fails, add -v to see the exact HTTP status and response:

vsp -v query T100
vsp -v install zadt-vsp

Full Changelog

• --verbose flag moved from rootCmd.Flags() to rootCmd.PersistentFlags()
• Added PersistentPreRunE to enable HTTP logging before subcommand execution
• SAP_VERBOSE env var now checked in CLI path via viper

v2.32.0: Full Stack ABAP

What's New in v2.32.0

Native ABAP Parser & Linter

• ABAP Lexer — mechanical port of abaplint to Go. 100% oracle match on 22,612 tokens across 29 files.
• Statement Parser — 91 statement types, 100% match on 3,254 statements. Colon chaining, NativeSQL, pragmas.
• ABAP Linter — 8 rules (line_length, empty_statement, obsolete_statement, etc.), 100% oracle match, 795μs/file. Works fully offline.

CLI Toolchain (28 commands)

Command	What	SAP needed?
`vsp query T000 --top 5`	Query SAP tables	Yes
`vsp grep "pattern" --package PKG`	Search source code	Yes

`vsp deps '$PKG' --format summary`	Transport readiness	Yes
`vsp lint --file src.abap`	ABAP linter	No
`vsp parse --stdin --format json`	ABAP parser	No

v2.30.0...v2.32.0

v2.30.0 — WASM Compiler + TS Transpiler + Unified Analyzer

WASM-to-ABAP AOT Compiler

Compile any WebAssembly binary to native ABAP. Three paths:

.wasm → pkg/wasmcomp (Go)  → ABAP source     (AOT compiler)
.ts   → pkg/ts2abap (Go)   → OO ABAP classes  (direct transpiler)
.wasm → zcl_wasm_compiler  → ABAP on SAP      (self-hosting, 785 lines)

QuickJS: 1,410 functions compiled, 100% opcodes, 101K lines ABAP.
abaplint: 26.5MB WASM compiled to 396K lines ABAP.

Self-Hosting Compiler on SAP

785 lines of ABAP parse any .wasm, generate ABAP, compile via
GENERATE SUBROUTINE POOL, and execute — all within SAP. No external tools.

TS-to-ABAP Direct Transpiler

TypeScript to clean OO ABAP without WASM intermediate. 800x smaller
output. abaplint lexer transpiled and running on SAP A4H.

Unified 5-Layer Code Intelligence

Combines regex (fast), parser (accurate), SCAN ABAP-SOURCE (SAP kernel),
CROSS/WBCROSSGT (index), and ADT Where-Used. Confidence scoring with
parser as primary authority, CROSS as supplementary.

Also in this release

• Hyperfocused mode (99.5% schema reduction) from v2.29.0
• Context compression (7-30x per dependency)
• Method-level surgery (95% token reduction)

v2.29.0 — Token Efficiency Sprint

Token Efficiency Sprint

This release is all about making every token count — hyperfocused mode, context compression, and method-level surgery work together to reduce token consumption by 10–75x.

Hyperfocused Mode — 1 Tool, 99.5% Less Schema

--mode hyperfocused registers a single SAP(action, target, params) tool instead of 122 individual tools.

Mode	Tools	Schema Tokens
Focused (default)	81	~14,000
Expert	122	~40,000
Hyperfocused	1	~200

All safety controls (read-only, allowed-ops, package restrictions) work identically across all modes.

Context Compression — 7-30x Per Dependency

GetSource auto-appends compressed dependency contracts (public API signatures only). One MCP call returns source + surrounding context. 10 regex patterns extract dependencies, contracts fetched in parallel, classes compressed to PUBLIC SECTION only.

Method-Level Surgery — 95% Source Reduction

Read/write individual methods without pulling entire classes:

SAP(action="read",  target="CLAS ZCL_FOO", params={"method": "CALCULATE"})
SAP(action="edit",  target="CLAS ZCL_FOO", params={"method": "CALCULATE", "source": "..."})

vsp handles fetch, splice, syntax check, push internally. Context compression scopes to the method's own dependencies.

ABAP LSP

vsp lsp --stdio provides real-time syntax checking and go-to-definition — zero token cost (runs via editor LSP channel, not MCP).

Mode Unification

SAP_TOOL_MODE removed. Now one axis: SAP_MODE=focused|expert|hyperfocused.

Combined Token Budget

Component	Expert Mode	Hyperfocused + Method	Ratio
Schema overhead	40,000	200	200x
Read + context	1,300	165	7.9x
Edit round-trip	2,100	210	10x
Total	43,600	575	75.8x

Platforms

Linux x64, ARM64, x86, ARM | macOS Intel, Apple Silicon | Windows x64, ARM64, x86
