FILEFLOW
A zero-dependency CLI for smarter file management
Track A — Developer Tools & CLI
Project Presentation
Python • Standard Library • argparse • pathlib • fnmatch
Built for the Zero Dependency 72-Hour Hackathon

01 • The Problem
Everyday file work becomes repetitive when the only tool is a graphical file explorer.
Manual discovery
Finding files across nested folders often means repeated clicking, scrolling and sorting.
Weak automation
Small file tasks are easy to repeat but awkward to automate without installing extra tools.
Dependency overhead
A simple utility should not need a large package stack just to inspect and search local files.
Goal
Build a lightweight, predictable CLI that works immediately with Python’s standard library.

02 • The Solution
FileFlow turns common file-discovery tasks into simple, scriptable commands.
● ● ●
$ python -m fileflow --help
FileFlow — zero-dependency CLI
$ python -m fileflow scan .
$ python -m fileflow search . --name "*.py"
Matches found: 4
fileflow\__main__.py� fileflow\scanner.py� fileflow\search.py
Simple
Human-readable commands and output.
Scriptable
Predictable exit codes and stderr errors.
Portable
No third-party runtime packages.

03 • Core Features
A focused feature set — small enough to understand, useful enough to demonstrate.
SCAN
Recursively inspect a directory and separate files from directories.
SEARCH
Find files by name pattern or extension.
VALIDATION
Reject invalid paths and conflicting search options clearly.
CLI UX
Built-in help, version information and structured commands.
EXIT CODES
Success and failure states are machine-readable for scripts.
ZERO DEP
Runtime uses Python standard-library modules only.

04 • Technical Design
Designed around standard-library building blocks instead of external frameworks.
CLI LAYER
argparse
COMMANDS
scan • search
FILE SYSTEM
pathlib
MATCHING
fnmatch

Project structure
fileflow/� __init__.py� __main__.py� scanner.py� search.py��The command layer stays separate from file-system logic, keeping the code easier to test and extend.
Why this architecture?
• Standard library only�• Clear separation of responsibilities�• Recursive traversal with pathlib�• Pattern matching with fnmatch�• Errors handled at the CLI boundary

05 • Reliability & Testing
The important part of a CLI is not only the happy path — it is predictable failure behavior.
Basic scan
Directory contents listed correctly
✓ PASS
Name search
Patterns such as *.py return matching files
✓ PASS
Extension search
--ext py and --ext .py work
✓ PASS
Missing path
Clear error + non-zero exit status
✓ PASS
Missing selector
Search without --name/--ext rejected
✓ PASS
Conflicting selectors
--name and --ext together rejected
✓ PASS
Result: the implemented scan/search flows were manually exercised in the terminal and passed the project’s current checks.

06 • Live Demo Plan
A 60–90 second terminal demo is enough to prove the project works.
1
Show help
python -m fileflow --help
2
Show version
python -m fileflow --version
3
Scan folder
python -m fileflow scan .
4
Search by name
python -m fileflow search . --name "*.py"
5
Search by extension
python -m fileflow search . --ext py
Tip: keep the terminal visible and let the commands speak for themselves.

07 • Zero-Dependency Commitment
The project follows the event’s core rule: no third-party runtime dependencies.
Runtime
Python 3.x�Standard library only��No pip packages required at runtime.
Libraries used
argparse�pathlib�fnmatch�sys��All are part of Python’s standard library.
Result
Easy setup�Low overhead�Portable design�Simple deployment��The tool can run directly with Python.
This keeps the implementation transparent: the core functionality is built from language/platform primitives rather than hidden behind packages.

08 • Conclusion
A compact developer tool that demonstrates practical CLI engineering.
FILEFLOW
From repetitive file discovery → to a scriptable workflow.
• Clean command-line interface
• Useful scan and search workflows
• Clear validation, errors and exit behavior
• Recursive file-system operations
• Zero third-party runtime dependencies
Why it fits Track A
Developer tool�CLI-first design�Sensible arguments�Automation-friendly behavior�Standard library only
