Erlang -- STDLIB

# STDLIB

###
Application

STDLIB

###
Application Summary

The STDLIB application.

###
Description

The STDLIB application is mandatory in the sense that the minimal system based on Erlang/OTP consists of Kernel and STDLIB. The STDLIB application contains no services.

###
Configuration

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_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.
