For the functionality of the GNU readline you should refer to
the readline's documentation.

Additional commands were introduced in a startup script

installation directory.

These commands are primarily for internal use and not documented here.

Note that all commands reside in the namespace \fB::tclreadline::\fP.

of the line). The default for this script is "puts {}; exit". Setting
this to an empty value disables any action on eof.
\fBtclreadline::readline eof\fP returns the current eof script.

\fB::tclreadline::readline initialize\fP \fIhistoryfile\fP
initialize the tclreadline interface and read the history from

the \fIhistoryfile\fP. On success an empty string is returned.
This command has to be called before any other tclreadline commands.

.TP 5
\fB::tclreadline::readline read\fP \fIprompt\fP
prints the \fIprompt\fP to stdout and enters the tclreadline event
loop. Both readline and X events are processed. Returns the
(eventually history-expanded) input string.

it is probably a good idea to start with tclreadline::Loop
(see the file tclreadlineSetup.tcl).

.TP 5
\fB::tclreadline::prompt1\fP
a proc which is called by ::tclreadline::Loop and returns a string
which will be displayed as the primary prompt. This prompt will be
something like "[info nameofexecutable] \[[pwd]\]" possibly fancy colored.
something like "[info nameofexecutable] \\[[pwd]\\]" possibly fancy colored.
The default proc is defined on entering the ::tclreadline::Loop,
if it is not already defined. So: If you define your own proc
::tclreadline::prompt1 before entering ::tclreadline::Loop, this
proc is called each time the prompt is to be displayed.
Example:
.CS
    package require tclreadline
    namespace eval tclreadline {
        proc prompt1 {} {
            return "[clock format [clock seconds]]> "
        }
    }
    ::tclreadline::Loop
.CE

Note that non-printable control characters as color control characters
must be enclosed in literal ctrl-a / ctrl-b to tell readline the length
of the printable prompt. See for example the variable `prompt_string'
in the file tclreadlineSetup.tcl in your tclreadline installation directory.

.TP 5
\fB::tclreadline::prompt2\fP
a proc which is called by ::tclreadline::Loop and returns a string
which will be displayed as the secondary prompt when interactively
prompting  for  continuation  of  an incomplete command.
