class Novika::RunnableResolver

• Novika::RunnableResolver
• Reference
• Object

Overview

A very high-level interface to the Novika resolver. Designed as one- shot, meaning you shouldn't reuse the same object twice or call #resolve? twice. In this regard, as a protection, calling #resolve? twice will raise.

See Session and Response if you want a lower-level interface.

resolver = Novika::RunnableResolver.new(cwd: Path[Dir.current], args: ["repl"])

# Define 'gets' and 'print' to ask for permissions.

resolver.on_permissions_gets do |string|
  print string
  gets
end

resolver.on_permissions_print do |string|
  print string
end

# Run "repl" and everything it requested.

resolver.after_permissions(&.run)
resolver.resolve?
