Class Method Details

.allow_breakpoints ⇒ Object

return true if breakpoints are allowed

# File 'lib/functions.rb', line 11

def self.allow_breakpoints
  @@allow_breakpoints
end

.breakpoint ⇒ Object

BlackStack::Debugging.breakpoint can be invoked in the middle of a running program. It opens a Pry session at the point it’s called and makes all program state at that point available. When the session ends the program continues with any modifications you made to it.

BlackStack::Debugging.breakpoint is just calling the Pry’s ‘binding.pry` method, but only if the @@allow_breakpoints is true.

# File 'lib/functions.rb', line 26

def self.breakpoint()
  # start a REPL session, if breakpoints are allowed

  binding.pry if @@allow_breakpoints
end

.set(h) ⇒ Object

set breakpoints allowed if the hash contains a key :allow_breakpoints with a value of true

# File 'lib/functions.rb', line 16

def self.set(h)
  @@allow_breakpoints = h[:allow_breakpoints] if h[:allow_breakpoints].is_a?(TrueClass)
