tool-versions-to-env

Is a tool to convert the variables in an asdf .tool-versions file into usable environment variables. It can grab a single variable to be used inline. It can dump the variables out to a .env file. It can dump the variables into a github action output. It outputs each library and version in the form of <library_name>_version=<version_number> for example the library in the .tool-versions file golang 1.18 will be converted to the equivalent environment variable golang_version=1.18.

This is useful when you want to hold versions for certain tools and libraries in one place but use the contained version elsewhere.

This repo contains:

• tool-versions-to-env shell script to convert .tool-versions into environment variables
• The github action workflow to use this tool in a github action
• The asdf plugin scripts to add the tool using asdf.
