Initialize the S-Lang readline routines
slsh_readline_init (String_Type appname)
The slsh_readline_init function is used to initialize the
S-Lang readline interface for use by an slsh-based application with
name appname. If defines an intrinsic variable called
__RL_APP__ whose value is given by appname. If the
file $HOME/.slrlinerc file exists, it will be loaded into the
interpreter. This file together with the __RL_APP__ variable
may be used by the user to customize the interface by, e.g., reading
previous history files, etc.
slsh_readline_new, rline_set_history
Instantiate a readline object
RLine_Type slsh_readline_new (String_Type name)
This function instantiates a new readline object with the specified name and returns it.
If a function called name_rline_open_hook exists, it will be
called with no arguments.
slsh_readline_init
Get input from the user with command line editing
String_Type slsh_readline ([RLine_Type r,] String_Type prompt)
The slsh_readline function utilizes the S-Lang readline
interface to read input from the terminal using the specified prompt.
If two parameters are given, the value of the first one must be a
RLine_Type object obtained previously from the
slsh_readline_new function.
slsh_readline_new, slsh_readline_init
Get input from the user with command line editing without echo
String_Type slsh_readline ([RLine_Type r,] String_Type prompt)
This function is like slsh_readline except that the input is
not echoed to the display. This makes it useful for reading
passwords, etc.
slsh_readline, slsh_readline_new, slsh_readline_init
Specify an alternate display update function for a readline object
slsh_set_readline_update_hook(RLine_Type rl [,&func [,funcdata]])
This function may be used to implement an alternative update hook
for the specified readline object. The hook must have one of the
following signatures, depending upon whether or not the optional
funcdata was given:
define func (rl, prompt, editbuf, editpoint) {...}
define func (rl, prompt, editbuf, editpoint, funcdata) {...}
If slsh_set_readline_update_hook is called with a single
argument, then any update hook associated with it will be set to the
default value.
slsh_readline_init, slsh_readline_new, slsh_readline
Specify a function to be called prior to reading via readline
slsh_set_upd
