envyaml
Simple YAML configuration file parser with easy access for structured data
Decision gist · record as of 2026-08-14
Yes, if you need environment-aware YAML configuration with dot-notation access and don't mind dormant maintenance. The package is stable and has no known vulnerabilities, but expect no active development—bug fixes or new features will not arrive. It's a good fit for small to medium projects with straightforward config needs; larger systems may prefer more actively maintained alternatives.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Low install friction; depends only on PyYAML.
- Maintenance is dormant—last release was 2022-01-08 and no commits since 2024-07-05, so expect no active bug fixes or feature updates.

What it is and what it does
EnvYAML is a lightweight YAML configuration parser that substitutes environment variables into your config files at parse time. It reads a YAML file, replaces placeholders like `$VAR_NAME` with values from your environment, and gives you dot-notation access to nested keys—so `env['database.host']` retrieves a deeply nested value without manual traversal. It also supports default values (e.g., `$VAR|default`) and escaping (e.g., `$$` for a literal `$`).
The package is built on top of PyYAML and adds a thin configuration layer. It's useful when you want to keep secrets and deployment-specific values out of version control but still maintain readable, structured config files. Strict mode (on by default) will raise an error if you reference an undefined environment variable, though you can disable it to allow missing vars to become None.
Use it for
- Load database credentials from environment variables into a YAML config file without hardcoding secrets
- Build multi-environment configs (dev, staging, prod) by varying environment variables at deploy time
- Access nested configuration sections with dot notation instead of nested dict lookups
- Provide fallback defaults for optional environment variables using the pipe syntax
- Parse complex YAML structures (lists, nested objects) while injecting runtime values
