galaxy-tool-source 0.1.0

Foundation library for parsing, profile-aware validation, and typed inspection of Galaxy tool XML

galaxy-tool-source

A Python library and small CLI for parsing, profile-aware validation, and typed inspection of Galaxy tool definition XML — the <tool> wrapper files that define Galaxy bioinformatics tools.

This package is the foundation for a separate, black-like program for Galaxy tool XML (conformance checking, autofixing, reformatting). It provides only the foundation — no rules, no formatter, no serializer:

1. Parse tool XML into a mutable representation that faithfully preserves CDATA, comments, attribute data and order, and significant element text.
2. A typed read-only view of a parsed tool — bound to the model for the tool's own schema profile — for convenient rule-checking.
3. Profile-aware XSD validation, with configurable macro handling so validation is accurate on real-world tools that use Galaxy macros.
4. Near-miss typo suggestions against the schema vocabulary (suggest only).

Install

uv sync

Usage

from galaxy_tool_source.binding import load_tool, validate_tool

document = load_tool("my_tool.xml")
print(document.profile)

result = validate_tool("my_tool.xml")
if not result.valid:
    for error in result.errors:
        print(error)

From the command line:

uv run galaxy-tool-source validate my_tool.xml
uv run galaxy-tool-source suggest my_tool.xml
uv run galaxy-tool-source profiles

Public API

The downstream formatter project may rely on exactly these symbols. Everything else is private and may change without notice.

Architecture

ToolDocument (document.py) wraps a mutable lxml tree — the source of truth, faithfully preserving CDATA, comments, and attribute order. binding.py parses and validates; profiles.py resolves the per-release vendored XSD; macros.py handles Galaxy macros (the sole galaxy-util adapter); corrections.py suggests near-miss typo fixes; boolean_values.py reports schema-boolean attribute value normalizations (True → true); cheetah_refs.py / cheetah_rename.py find and rename a parameter across a tool's Cheetah sections (the latter renders the rename either as a tree mutation, rename_param, or as minimal source offsets, rename_param_plan, for editor / LSP use); bundle.py extends the rename across a tool and its imported macro files (ToolBundle / load_bundle / rename_param_in_bundle); rst.py / rst_markdown.py own the <help> reStructuredText subsystem — validity + surgical repair (the GTR089 partition seam) and the render-equivalence-gated RST → Markdown conversion (GTR092; needs the [markdown] extra); models/ holds an xsdata-generated read-only typed model for every vendored schema version, reached via ToolDocument.model().
