history

Project history and usage

shyaml is a cross-platform command-line YAML reader designed for shell pipelines. It reads YAML exclusively from standard input and can return values, types, keys, or YAML substructures.

Project history

The project originated as a small Python utility for extracting values and substructures from YAML in shell scripts. Upstream now describes the Python version as being in a lethargic state, limited mainly to critical fixes, while active development continues in shyaml-rs.

Adoption history

The official README documents distribution through PyPI and Homebrew and support for Linux, macOS, and Windows. The supplied package metadata also lists Homebrew and DNF package names.

How it is used

Typical use redirects or pipes a YAML document into `shyaml`, followed by an action and key. The `--yaml` option produces YAML-safe output for recursive processing, while version output reports the PyYAML and libyaml implementations in use.

Why package nerds care

shyaml represents the Unix-pipeline approach to structured data: YAML arrives on standard input, a key or substructure is selected, and the result can feed another command. Its current upstream status also illustrates package succession, with the Python implementation pointing users toward the faster, compatible shyaml-rs rewrite.

Timeline

Before 0.4.0: Mapping keys were emitted in sorted order.
0.4.0: Mapping insertion order began to be preserved.
Current upstream status: Python shyaml entered limited maintenance while shyaml-rs became the active successor.

Related projects

PyYAML supplies the Python YAML implementation used by shyaml.
shyaml-rs is the upstream-recommended Rust rewrite and is intended as a drop-in replacement.
