The c module enables users to enter the short form of
some commonly used commands.
 |
These functions are are intended for interactive use in the Erlang shell only. The module prefix may be omitted. |
Types:
Pid = pid()
Stack backtrace for a process. Equivalent to
erlang:process_display(Pid, backtrace).
c(File) -> {ok, Module} | error
c(File, Options) -> {ok, Module} | error
Types:
File = Filename | Module
Filename = string() | atom()
Options = [Opt] -- see compile:file/2
Module = atom()
c/1,2 compiles and then purges and loads the code for
a file. Options defaults to []. Compilation is
equivalent to:
compile:file(File, Options ++ [report_errors, report_warnings])
Note that purging the code means that any processes
lingering in old code for the module are killed without
warning. See code/3 for more information.
Types:
Dir = string() | atom()
Changes working directory to Dir, which may be a
relative name, and then prints the name of the new working
directory.
2> cd("../erlang").
/home/ron/erlang
Flushes any messages sent to the shell.
Displays help information: all valid shell internal commands, and commands in this module.
i/0 displays information about the system, listing
information about all processes. ni/0 does the same,
but for all nodes the network.
Types:
X = Y = Z = int()
Displays information about a process, Equivalent to
process_info(pid(X, Y, Z)), but location transparent.
Types:
Module = atom()
Purges and loads, or reloads, a module by calling
code:purge(Module) followed by
code:load_file(Module).
Note that purging the code means that any processes
lingering in old code for the module are killed without
warning. See code/3 for more information.
Types:
Files = [File]
File = Filename | Module
Filename = string() | atom()
Module = atom()
Compiles a list of files by calling compile:file(File,
[report_errors, report_warnings]) for each File
in Files.
Lists files in the current directory.
Types:
Dir = string() | atom()
Lists files in directory Dir.
Displays information about the loaded modules, including the files from which they have been loaded.
Types:
Module = atom()
Displays information about Module.
Types:
Type, Size -- see erlang:memory/0
Memory allocation information. Equivalent to
erlang:memory/0.
memory(Type) -> Size
memory([Type]) -> [{Type, Size}]
Types:
Type, Size -- see erlang:memory/0
Memory allocation information. Equivalent to
erlang:memory/1.
nc(File) -> {ok, Module} | error
nc(File, Options) -> {ok, Module} | error
Types:
File = Filename | Module
Filename = string() | atom()
Options = [Opt] -- see compile:file/2
Module = atom()
Compiles and then loads the code for a file on all nodes.
Options defaults to []. Compilation is equivalent to:
compile:file(File, Opts ++ [report_errors, report_warnings])
Types:
Module = atom()
Loads Module on all nodes.
Types:
X = Y = Z = int()
Converts X, Y, Z to the pid
<X.Y.Z>. This function should only be used when
debugging.
Prints the name of the working directory.
This function is shorthand for init:stop(), that is,
it causes the node to stop in a controlled fashion.
regs() -> void()
nregs() -> void()
regs/0 displays information about all registered
processes. nregs/0 does the same, but for all nodes
in the network.
Types:
ModSpec = Module | Filename
Module = atom()
Filename = string()
This function finds undefined functions and unused
functions in a module by calling xref:m/1.
