🪡📦 craftbox

A collection of custom-tailored scripts and applied utilities built with Viash.

Introduction

craftbox is a curated collection of custom scripts and utilities designed to tackle context-specific tasks.

Emphasizing the Viash principles, craftbox components aim for reusability, reproducibility, and adherence to best practices. Key features generally include:

• Standalone & Nextflow Ready: Components are built to run directly via the command line or be smoothly integrated into Nextflow workflows.
• Custom Implementations: Contains scripts and tools developed for particular tasks that may not be found in broader collections.
• High Quality Standards (promoted by Viash):
  • Clear documentation for components and their parameters.
  • Full exposure of underlying script/tool arguments for fine-grained control.
  • Containerized (Docker) to ensure dependency management and a consistent, reproducible runtime environment.
  • Unit tested where applicable to ensure components function as expected.

Example Usage

Viash components in craftbox can be run in various ways:

flowchart TD
    A[craftbox v0.3.1] --> B(Viash Hub Launch)
    A --> C(Viash CLI)
    A --> D(Nextflow CLI)
    A --> E(Seqera Cloud)
    A --> F(As a dependency)

Loading

1. Via the Viash Hub Launch interface

You can run this component directly from the Viash Hub Launch interface.

2. Via the Viash CLI

You can run this component directly from the command line using the Viash CLI.

viash run vsh://craftbox@v0.3.1/concat_rtext -- --help

viash run vsh://craftbox@v0.3.1/concat_rtext -- \
  --input path/to/input.txt \
  --input path/to/compressed.txt.gz \
  --output path/to/output.txt

This will run the component with the specified input files and output the results to the specified output file.

3. Via the Nextflow CLI or Seqera Cloud

You can run this component as a Nextflow pipeline.

nextflow run https://packages.viash-hub.com/vsh/craftbox \
  -revision v0.3.1 \
  -main-script target/nextflow/concat_rtext/main.nf \
  -latest -resume \
  -profile docker \
  --input "path/to/input.txt;path/to/compressed.txt.gz" \
  --output path/to/output.txt

Note: Make sure that the Nextflow SCM is set up properly. You can do this by adding the following lines to your ~/.nextflow/scm file:

providers.vsh.platform = 'gitlab'
providers.vsh.server = 'https://packages.viash-hub.com'

Tip: This will also work with Seqera Cloud or other Nextflow-compatible platforms.

4. As a dependency

In your Viash config file (config.vsh.yaml), you can add this component as a dependency:

dependencies:
  - name: concat_rtext
    repository: vsh://craftbox@v0.3.1

Tip: See the Viash documentation for more details on how to use Viash components as a dependency in your own Nextflow workflows.
