## What it is
Oneliner-izer is a Python tool that converts any Python 2 script into a single line of code using lambda expressions, list comprehensions, and other tricks, without newlines, semicolons, or eval/exec. It is available as a pip-installable CLI and Python module, with a live web demo.

## Use cases
- convert a python script into one line
- turn python code into a single line for code golf
- onelinerize a python 2 file
- compress python code into one line without semicolons
- learn how to write python one-liners with lambdas
- transform multi-line python programs into lambda expressions

## When to choose
- you want to convert Python 2 scripts into a single line for fun, code golf, or constrained coding exercises
- you want a pip-installable CLI or importable module for one-lining Python code
- you want to study lambda-based tricks for emulating statements, loops, and functions

## When to avoid
- you need production-quality code transformation or refactoring of Python 3 code
- you need readable, maintainable output
- you need a general-purpose Python minifier or obfuscator with performance goals

## Facets
- artifact type: cli-tool
- maturity: maintenance
- function: parser, compiler, developer-tools, cli
- domain: developer-tools, programming-languages, parsers
- platform: python, cli, cross-platform
- tags: code-golf, python-2, code-transformation, novelty, lambda-calculus, command-line
