A shiny app to format Common Workflow Language (CWL) apps using the Python package cwlformat.

This app uses reticulate to call Python and the Python package cwlformat. Follow its readme to install the Python package either using pip or from GitHub.

After the Python package is installed, modify .Rprofile to give a hint to reticulate on where to find Python and the installed package. The default location is for a macOS Homebrew Python 3. Relaunch the RStudio session to use this profile.

If you encountered an error on unable to import the Python module, please consult the articles Python Version Configuration and Installing Python Packages, then add a few lines to server/wrapper.R before reticulate::import to help reticulate locate the Python package. For example, if we use virtualenv:

use_python("/your/path/to/bin/python3")

virtualenv_create("venv", python = "/your/path/to/bin/python3")
virtualenv_install("venv", packages = c("cwlformat"), ignore_installed = FALSE)
use_virtualenv("venv", required = TRUE)
