If Module is a list of modules, the result of the last module is returned.

If an interpreted module is compiled using the c:c function, this module is reloaded into the interpreter.

iq(Module) -> ok

Types

Module = atom() | string() | [atom() | string()]

Does not interpret Module. The Module parameter can either be a single module name, or a list of module names. Module is removed from the set of modules currently being interpreted.

ini(Module) -> {module,Module} | error | ok

inq(Module) -> ok

Behaves as the corresponding ii/1 and iq/1 functions described above, but on all nodes in the network. It returns ok if we are alive, otherwise as above.

il() -> ok

Makes a printout of all interpreted modules. Modules are printed together with the full path name of the corresponding source code file.

ip() -> ok

Makes a printout of the current status of all interpreted processes. Processes on all known nodes are printed.

ic() -> ok

Deletes (clears) information about all terminated processes from the interpreter.

iaa(Flag) -> true

Types

Flag = FlagItem | [FlagItem]

FlagItem = init | break | exit | false

Interpreted processes can be attached automatically, without the need to attach to a process using the monitor window, i:im() or int:m(). An attachment window - not described here - pops up for the attached process. Flag specifies at which point interpreted processes are automatically attached.

Flag is one of:

*

init. Attach to a process the very first time it calls an interpreted function.

*

break. Attach to a process whenever it reaches a break point.

*

exit. Attach to a process when it terminates.

*

false. Deactivate the automatic attach facility.

If several conditions are to be active, a list of flags must be given.

iaa(Flag,Function) -> true

Types

Flag = FlagItem | [FlagItem]

FlagItem = init | break | exit | false

Function = {Mod, Func}

Mod = atom()

Fun = atom()

As above, but instead of using the default attachment window, the specified Function is used in order to start the interaction with the attached process. The Function parameter must be the tuple {Mod, Func}, and this function should implement the corresponding functionality in the same way as the int_show:a_start/3, 4 functions.

ist(Flag) -> true

Types

Flag = all | true | no_tail | false

The interpreter can keep call frames in the stack for future inspections. Typically, you can go up and down in the stack in order to inspect the flow of control when the execution has been stopped - at a break point, when the process has terminated, or in a single step execution.

By default, the whole stack is kept (Flag = all or true). If processes with a very long life time and with a lot of tail recursive calls are interpreted, the no_tail flag should be used. No tail recursive calls are kept in the stack if this flag is used.

The false flag should be used if the interpreter is not to keep call frames.

ia(Pid) -> ok | no_proc

Types

Pid = pid()

Attaches to the Pid process. An attachment window pops up.

ia(X,Y,Z) -> ok | no_proc

Types

X = Y = Z = int()

Attaches to the process with process identity c:pid(X,Y,Z). An attachment window pops up.

ia(Pid,Function) -> ok | no_proc

Types

Pid = pid()

Function = {Mod, Fun}

Mod = atom()

Fun = atom()

Attaches to the Pid process. Use Function for the interaction with the attached process, as for the i:iaa/2 function.

ia(X,Y,Z,Function) -> ok | no_proc

Types

X = Y = Z = int()

Function = {Mod, Fun}

Mod = atom()

Fun = atom()

Attaches to the process with process identity c:pid(X,Y,Z). Use Function for the interaction with the attached process, as for the i:iaa/2 function.

ib(Module,Line) -> ok | {error, What}

Types

Module = atom()

Line = int()

What = badarg | break_exists

Creates a new break point at Line in Module. The execution of an interpreted process will be stopped before the expression at Line in Module is executed.

ib(Module,Function,Arity) -> ok | {error, What}

Types

Module = atom()

Function = atom()

Arity = int()

What = badarg | function_not_found

Creates break points at the first line in every clause of the Module:Function/Arity function.

ir(Module,Line) -> ok | {error, What}

Types

Module = atom()

Line = int()

What = badarg | no_break_exists

Deletes the break point located at Line in Module.

ir() -> ok

Deletes all existing break points.

ir(Module) -> ok

Types

Module = atom()

Deletes all existing break points in Module.

ir(Module,Function,Arity) -> ok | {error, What}

Types

Module = atom()

Function = atom()

Arity = int()

What = badarg | function_not_found

Deletes break points at the first line in every clause of the Module:Function/Arity function.

ibd(Module,Line) -> ok | {error, What}

Types

Module = atom()

Line = int()

What = badarg | no_break

Makes the break point at Line in Module inactive. The break point still exists, but no processes will be stopped at the break point.

ibe(Module,Line) -> ok | {error, What}

Types

Module = atom()

Line = int()

What = badarg | no_break

Makes the break point at Line in Module active. Processes will again be stopped at the break point.

iba(Module,Line,Action) -> ok | {error, What}

Types

Module = atom()

Line = int()

Action = enable | disable | delete

What = badarg | no_break

Sets the status of the break point at Line in Module after it is triggered the next time. Action is: enable, disable, or delete.

ibc(Module,Line,Function) -> ok | {error, What}

Types

Module = atom()

Line = int()

Function = {M, F}

Mod = atom()

Func = atom()

What = badarg | no_break

Makes the break point at Line in Module conditional. Function is called whenever the break point is reached. Function is a tuple {Mod, Func}. Function must have arity 1 and return either true or false. This way, the break point either triggers, or not. The argument to Function is the current variable bindings of the process at the place of the break point. The bindings can be inspected using int:get_binding/2.

ipb() -> ok

Makes a printout of all existing break points.

ipb(Module) -> ok

Types

Module = atom()

Makes a printout of all existing break points located in Module.

iv() -> atom()

Returns the current version number of the interpreter.

help() -> ok

Prints help text.
