Add version utility functions to plugin API for topic channel support #23

Copilot · 2025-10-16T16:29:14Z

Overview

This PR exposes three essential version utility functions to the plugin API that are required by the nf-core pipeline template and enable proper topic channel support for version management.

Problem

The nf-core/tools pipeline template uses three key functions for version management:

processVersionsFromYAML()
workflowVersionToYAML()
softwareVersionsToYAML()

While these functions existed in the plugin's NfcoreVersionUtils utility class with comprehensive implementation and test coverage, they were not exposed as @Function methods in NfUtilsExtension, making them inaccessible to Nextflow pipelines.

Solution

Added three @Function annotated wrapper methods to NfUtilsExtension that delegate to the existing, well-tested utility implementations:

1. `processVersionsFromYAML(String yamlFile)`

Parses and flattens YAML version strings by removing nested tool prefixes.

Example:

def yamlContent = """
tool:fastqc: 0.12.1
samtools: 1.17
"""
def processed = processVersionsFromYAML(yamlContent)
// Result: "fastqc: 0.12.1\nsamtools: 1.17"

2. `workflowVersionToYAML()`

Returns workflow version information as formatted YAML, including workflow name, version, and Nextflow version.

Example:

def workflowYaml = workflowVersionToYAML()
// Result:
// Workflow:
//     nf-core/rnaseq: v3.12.0-gabcdef1
//     Nextflow: 23.04.1

3. `softwareVersionsToYAML(List<String> chVersions)`

Primary function - Combines version YAMLs from multiple processes, deduplicates entries, and appends workflow version info. This matches the standard nf-core pipeline pattern.

Example:

include { softwareVersionsToYAML } from 'plugin/nf-core-utils'

workflow PIPELINE {
    ch_versions = Channel.empty()
    
    FASTQC(samples)
    ch_versions = ch_versions.mix(FASTQC.out.versions.first())
    
    MULTIQC(reports)
    ch_versions = ch_versions.mix(MULTIQC.out.versions.first())
    
    // Generate unified versions file
    softwareVersionsToYAML(ch_versions.collect())
        .collectFile(
            name: 'software_versions.yml',
            storeDir: "${params.outdir}/pipeline_info"
        )
}

Changes

src/main/groovy/nfcore/plugin/NfUtilsExtension.groovy: Added three @Function methods with comprehensive JavaDoc
docs/utilities/NfcoreVersionUtils.md: Added detailed documentation with usage examples and integration patterns
CHANGELOG.md: Documented new functions in Unreleased section

Testing

The underlying utility functions have comprehensive test coverage (15+ tests) in NfcoreVersionUtilsTest.groovy. The extension methods are thin wrappers that delegate to these tested implementations.

Benefits

✅ Enables nf-core pipelines to use plugin-based version utilities
✅ Matches nf-core/tools pipeline template patterns exactly
✅ Supports progressive migration from subworkflows to plugin
✅ Fully backward compatible with no breaking changes
✅ Ready for nf-core Hackathon

Closes #[issue_number]
