Decision gist · record as of 2026-08-14
Yes. The package is actively maintained, has low install friction, carries a permissive MIT license, and fills a clear need for developers working with Galaxy workflows. It supports current Python versions and has no known vulnerabilities. Install it if you work with Galaxy workflows and want to use or validate the Format 2 YAML-based format.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python 3.9 or later; schema-salad dependency may require system libraries for XML/YAML processing.
- Low friction installation with six runtime dependencies (pydantic, pyyaml, requests, schema-salad, eval_type_backport, typing_extensions).
- Actively maintained with a commit as recent as 2026-08-11 and releases within the past 79 days.

What it is and what it does
gxformat2 is a Python library for working with Galaxy's Format 2 workflow description language, a YAML-based alternative to Galaxy's traditional .ga workflow format. It provides parsing, validation, and conversion utilities to help developers and workflow authors work with Galaxy workflows in a more human-readable and concise form. The package includes both a Python API for programmatic use and command-line tools for linting, visualization, and format conversion.
The library depends on pydantic for validation, pyyaml for YAML parsing, schema-salad for schema handling, and requests for HTTP operations. It supports Python 3.9 through 3.14 and is actively maintained. Format 2 is still somewhat experimental and may change in backward-incompatible ways, though it has been consumable by Galaxy since version 19.09.
Use it for
- Validate Galaxy workflow definitions written in Format 2 YAML before deploying to a Galaxy instance.
- Convert existing Galaxy native workflows (.ga files) to the more readable Format 2 format for human editing.
- Lint and visualize Galaxy workflows using the included command-line tools (gxwf-lint, gxwf-viz).
- Integrate workflow format conversion into Planemo or other Galaxy development tools.
- Generate abstract workflow exports for documentation or sharing workflow logic without implementation details.
