Debug

Reading and writing constants, upvalues, protos, stack frames, and standard profiling.

Available Functions

Function	Description
debug.getcallstack	Returns a table of the entire stack's information. Table array fields: source (definition), line (start line), what (\"Lua\", \"C\"), name, func.
debug.getconstant	Returns a singular constant that's derived from a function. Selected via index.
debug.getconstants	Returns a table of constants that's derived from a function.
debug.getinfo	Returns a table of information that's derived from a function or stack level.
debug.getproto	Gets a cloned proto inside the 'func' unless the 'active' is specified which returns a table of all active protos.
debug.getprotos	Return a list of all cloned protos.
debug.getregistry	Returns the global registry table. The registry is used to store references. Any object referenced in the registry will never be collected by the garbage collector, as the registry itself will never be collected. Thus a strong reference will always be held.
debug.getsafeenv	Returns the safeenv flag.
debug.getstack	Returns a table (of the stack) or a singular object from the stack. Only returns objects that are currently on the stack.
debug.getupvalue	Returns a singular upvalue that's derived from a function's upvalue list. Selected via index.
debug.getupvalues	Returns a table of upvalues from a function's upvalue's list.
debug.info	Returns debug information about a given stack frame or function object based on the options string (that can contain characters nslfa).
debug.isvalidlevel	Checks if 'level' is valid in the stack
debug.profilebegin	Opens a microprofiler label.
debug.profileend	Closes the top microprofiler label.
debug.setconstant	Sets a singular constant that's derived from a function. Selected via index.
debug.setinfo	Sets the debug info around the 'func'.
debug.setname	Changes the function name specified to the set one.
debug.setsafeenv	Marks the safeenv for an object.
debug.setstack	Sets a singular object from the stack.
debug.setupvalue	Sets a singular upvalue that's derived from a function's upvalue list. Selected via index.
debug.traceback	Returns a string with a traceback of the call stack. The optional message string is appended at the beginning of the traceback.
