Visual Exploration

Understand every dependency at a glance.

Exhaustive AST parsing of .vbp, .frm, .bas, .cls, and .ctl files. Explore call hierarchies with 4 tailored layout algorithms.

Radial, Affinity, Clustered Islands, and Force-Directed physics layouts.
Dynamic member expansion for classes and modules with granular method mapping.
Fluid 60 FPS rendering even across large enterprise codebases with 10,000+ symbols.

AST Resolution Pipeline:

• 14 Forms (.FRM) → UI Event Handlers

• 22 Standard Modules (.BAS) → Global Routines

• 18 Class Modules (.CLS) → Instantiations & Members

Total: 1,482 calls resolved (32ms cold parse)

Recursive Impact Formula:

Depth: 6 levels

Direct Callers: 18 | Indirect: 142

Touched UI Forms: 11 forms

Regression Risk Score: CRITICAL (94/100)

Impact Analysis

Refactor without fear of breaking production.

The Blast Radius matrix recursively traces all upstream callers. Know which UI forms or business entities will be touched before editing a single line.

Automated regression risk ratings from Low to Critical.
Interactive audit grid sorted by total impact and call depth.
1-click instant navigation from audit rows to the exact graph node.

AI & Modernization

The ideal bridge between legacy code and AI models.

Extract compact, structured Markdown Repo Maps and semantic context slices ready for Claude, ChatGPT, Gemini, Copilot, etc. to guide your C#/.NET or modern architecture rewrite.

Targeted subgraphs that minimize token noise and maximize LLM accuracy.
Zero hallucinations: the LLM receives verified AST, CALLS relationships, and resolved types.
Headless CLI execution for CI/CD pipelines or as a tool for autonomous AI agents (Claude Code, Cursor, Antigravity, MCP, etc.).

# Export project Markdown Repo Map

Macondo.exe analyze "C:\Projects\MyLegacyProject" --export-md "repo-map.md"

# Export complete semantic graph to JSON

Macondo.exe analyze "C:\Projects\MyLegacyProject\App.vbp" --export-json "graph.json"

# Export both formats simultaneously

Macondo.exe analyze "C:\Projects\MyLegacyProject" --export-md "repo-map.md" --export-json "graph.json"
