asdf-discover

A gem that provides an executable to populate asdf's .tool-versions file.

Changelog following https://keepachangelog.com

$ gem install asdf-discover

Run asdf-discover in a project directory.

• If a version comes from multiple sources, list them all (currently displays the first found)

• Select a version from asdf list tool for versions specified with a requirement, e.g. "~> 1.10"

• There seems to be 2 ways to find a version:

  • The contents of a file (e.g. .ruby-version)
  • A line in a file (e.g. go.mod)

  Consider a DSL for adding more:

  class GoMod
    include Asdf::Searcher
  
    scan_file "go.mod", for: /go ([0-9.]+)$/
  end
  
  class DotRubyVersion
    include Asdf::Searcher
  
    file_contents ".ruby-version"
  end

After checking out the repo, run bundle install. Then, run rake spec to run the tests.

You can run the binary locally with: ruby -Ilib ./exe/asdf-discover path/to/directory
