#compile_string(source, options = {}) ⇒ Hash

Compile T-Ruby source code from a string (useful for WASM/playground)

Parameters:

    Options for compilation

Options Hash (options):

  • :rbs (Boolean) —

    Whether to generate RBS output (default: true)

Returns:

  • Result with :ruby, :rbs, :errors keys
