shell_default.3erl

NAME

shell_default - Customizing the Erlang Environment

DESCRIPTION

The functions in shell_default are called when no module name is given in a shell command.

Consider the following shell dialogue:

 
 1 > lists:reverse("abc").
 "cba"
 2 > c(foo).
 {ok, foo}    
 

In command one, the module lists is called. In command two, no module name is specified. The shell searches the modules user_default followed by shell_default for the function foo/1.

shell_default is intended for "system wide" customizations to the shell. user_default is intended for "local" or individual user customizations.

HINT

To add your own commands to the shell, create a module called user_default and add the commands you want. Then add the following line as the first line in your .erlang file in your home directory.

 
 code:load_abs("$PATH/user_default").    
 

$PATH is the directory where your user_default module can be found.
