Sommaire
NAME
c - Command Interface ModuleDESCRIPTION
The c module enables users to enter the short form of some commonly used commands.
- Note:
- These functions are are intended for interactive use in the Erlang shell only. The module prefix may be omitted.
EXPORTS
bt(Pid) -> void()
-
- 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 = name() -- see filename(3erl)
Options = [Opt] -- see compile:file/2
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.
cd(Dir) -> void()
-
- Types
- Dir = name() -- see filename(3erl)
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
flush() -> void()
Flushes any messages sent to the shell.
help() -> void()
Displays help information: all valid shell internal commands, and commands in this module.
i() -> void()
ni() -> void()
i/0 displays information about the system, listing information about all processes. ni/0 does the same, but for all nodes the network.
i(X, Y, Z) -> void()
-
- Types
- X = Y = Z = int()
Displays information about a process, Equivalent to process_info(pid(X, Y, Z)), but location transparent.
l(Module) -> void()
-
- 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.
lc(Files) -> ok
-
- Types
- Files = [File]
File = name() -- see filename(3erl)
Compiles a list of files by calling compile:file(File, [report_errors, report_warnings]) for each File in Files.
ls() -> void()
Lists files in the current directory.
ls(Dir) -> void()
-
- Types
- Dir = name() -- see filename(3erl)
Lists files in directory Dir.
m() -> void()
Displays information about the loaded modules, including the files from which they have been loaded.
m(Module) -> void()
-
- Types
- Module = atom()
Displays information about Module.
memory() -> [{Type, Size}]
-
- 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 = name() -- see filename(3erl)
Options = [Opt] -- see compile:file/2
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])
nl(Module) -> void()
-
- Types
- Module = atom()
Loads Module on all nodes.
pid(X, Y, Z) -> pid()
-
- Types
- X = Y = Z = int()
Converts X, Y, Z to the pid <X.Y.Z>. This function should only be used when debugging.
pwd() -> void()
Prints the name of the working directory.
q() -> void()
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.
xm(ModSpec) -> void()
-
- Types
- ModSpec = Module | Filename
Module = atom()
Filename = string()
This function finds undefined functions, unused functions, and calls to deprecated functions in a module by calling xref:m/1.
y(File) -> YeccRet
-
- Types
- File = name() -- see filename(3erl)
YeccRet = -- see yecc:file/2
Generates an LALR-1 parser. Equivalent to:-
yecc:file(File)
y(File, Options) -> YeccRet
-
- Types
- File = name() -- see filename(3erl)
Options, YeccRet = -- see yecc:file/2
Generates an LALR-1 parser. Equivalent to:-
yecc:file(File, Options)
