Instance Method Details

#client ⇒ Object

Lets an object that will forward method calls to the breakpoint client. This is useful for outputting longer things at the client and so on. You can for example do these things:

client.puts "Hello" # outputs "Hello" at client console
# outputs "Hello" into the file temp.txt at the client
client.File.open("temp.txt", "w") { |f| f.puts "Hello" }

#source_lines(context = 5, return_line_numbers = false) ⇒ Object
