The following configuration parameters are defined for the STDLIB application. For more information about configuration parameters, see the app(4) module in Kernel.

shell_esc = icl | abort

Can be used to change the behavior of the Erlang shell when ^G is pressed.

restricted_shell = module()

Can be used to run the Erlang shell in restricted mode.

shell_catch_exception = boolean()

Can be used to set the exception handling of the evaluator process of Erlang shell.

shell_expand_location = above | below

Sets where the tab expansion text should appear in the shell. The default is below.

shell_redraw_prompt_on_output = boolean()

Sets whether the shell should redraw the prompt when it receives output from other processes. This setting can be useful if you use run_erl to for logging as redrawing the prompt will emit a lot of ANSI escape characters that you normally do not want in a log. The default is true.

shell_history_length = integer() >= 0

Can be used to determine how many commands are saved by the Erlang shell. See edlin for more.

shell_keymap = #{}

Can be used to override the default keymap configuration for the shell.

shell_prompt_func = {Mod, Func} | default

where

• Mod = atom()
• Func = atom()

Can be used to set a customized Erlang shell prompt function.

shell_saved_results = integer() >= 0

Can be used to determine how many results are saved by the Erlang shell.

shell_session_slogan = string() | fun() -> string())

The slogan printed when starting an Erlang shell. Example:

$ erl -stdlib shell_session_slogan '"Test slogan"'
Erlang/OTP 26 [DEVELOPMENT] [erts-13.0.2] [source] [64-bit] [smp:8:8] [ds:8:8:10] [async-threads:1] [jit:ns]

Test slogan
1>

shell_slogan = string() | fun(() -> string())

The slogan printed when starting the Erlang shell subsystem. Example:

$ erl -stdlib shell_slogan '"Test slogan"'
Test slogan
Eshell V13.0.2  (abort with ^G)
1>

The default is the return value of erlang:system_info(system_version).

shell_strings = boolean()

Can be used to determine how the Erlang shell outputs lists of integers.
