escapism
Simple, generic API for escaping strings.
Decision gist · record as of 2026-08-14
Yes. Escapism is a stable, dependency-free utility with a clear, minimal API and active maintenance. It's well-suited for any project needing string escaping or Kubernetes-compatible slug generation. No known vulnerabilities, permissive license, and low install friction make it a safe choice.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python 3.9 or later.
- Low install friction with no runtime dependencies.
- Actively maintained as of 2026-08-01 with a stable release history since 2015.

What it is and what it does
Escapism is a lightweight string escaping library that converts unsafe characters into escape sequences using a configurable escape character (default: underscore). It provides two main APIs: a reversible escape/unescape pair for general text escaping, and a lossy slug generator designed for Kubernetes resource naming that enforces strict validity rules (lowercase, alphanumeric plus hyphens, length 1–63, starting with a letter). The slug function is useful when you need a valid identifier but don't need to recover the original string; it applies hashing to ensure uniqueness when the input violates validity constraints.
The package has no runtime dependencies and installs as a pure Python wheel. It's actively maintained and used in production by JupyterHub-related projects. The API is minimal—just two functions with optional arguments for customizing the escape character and safe-character set—making it straightforward to integrate into any text-processing pipeline that needs controlled character escaping or identifier generation.
Use it for
- Escape special characters in strings for use in URLs, filenames, or configuration keys while preserving reversibility.
- Generate valid Kubernetes object names and label values from arbitrary user input with automatic hashing for collision avoidance.
- Sanitize usernames or identifiers to meet strict naming constraints (length, character set, start/end rules) in distributed systems.
- Encode text for storage in systems with restricted character sets while maintaining the ability to decode it later.
- Create URL-safe slugs from user-provided strings for web applications or APIs.
