# This file is part of the Ceylan-Myriad library.





# Typically used internally to Myriad, by system_utils:get_line/1.



# This (most simple) script allows to collect user inputs, as lines entered

# thanks to the keyboard (ex: for text_ui.erl) even if the Erlang VM is run with

# the -noinput setting, which apparently is necessary for other forms of user

# interactions such as /bin/dialog (see term_ui.erl).





# No prompt actually allowed, as no writing to the "standard" output can/should

# be done here (file descriptor 1, actually redirected to 4).



#prompt="$1"

#

#if [ -n "${prompt}" ] ; then

#	echo "prompt: $1"

#fi
