Welcome to ASPPY
ASPPY is a transpiler bridging the gap between legacy Classic ASP/VBScript applications and modern Python ecosystems. With a 99% compatibility guarantee, it runs standard VBScript logic natively on a Python VM.
How does ASPPY differ from legacy ASP/VBScript?
ASPPY is designed to run existing legacy VBScript mostly unmodified. Your familiar objects like Response, Request, Server, Session, and Application work as expected.
However, the key difference lies in the introduction of the new ASPPY global class. Instead of relying on aging or unavailable COM components (like Persits.Jpeg, Persits.Pdf, Chilkat, or bespoke Scripting.FileSystemObject scripts), ASPPY brings modern capabilities securely and natively:
- ASPPY.zip: File compression leveraging Python's
zipfile. - ASPPY.pdf: Direct PDF generation via
fpdf2. - ASPPY.image: Advanced image processing utilizing
Pillow. - ASPPY.crypto: Robust password hashing using
bcrypt. - ASPPY.json: Native JSON encoding/decoding, eliminating the need for slow VBScript parsers.
- ASPPY.pop3 & ASPPY.imap: Built-in modern mail clients.
- ASPPY.ExecutePython: Run any Python code or package (
numpy,pandas,psutil, etc.) directly from VBScript, bridging legacy ASP to the full Python ecosystem.
Testing pages from the command line
ASPPY ships a CLI runner, asppycli.py, that renders any .asp page offline through the same VM pipeline as the HTTP server — no server, no port, no browser. It is the recommended verification tool for AI agents and CI scripts building ASPPY apps: the exit code tells you instantly whether a page rendered cleanly.
