.SH NAME
tclreadline \- gnu readline for the tcl scripting language


.SH SYNOPSIS
.TP 6
\fB::tclreadline::readline\fP \fIcommand\fP [\fIoptions\fP]


.SH DESCRIPTION

The \fBtclreadline\fP package makes the gnu readline available
to the scripting language tcl. The primary purpose of the package
is to facilitate the interactive script development by the means
of word and file name completion as well as history expansion
(well known from shells like bash).

................................................................................

\fBtclreadline\fP is basically a shared library and a few tcl scripts
which are accessed with the tcl package require command. Therefore
\fBtclreadline\fP should work with all common extensions like
\fBblt, itcl, itk, tix ...\fP.


.\".SH SOURCE FILES


.SH COMMANDS

If you want to use \fBtclreadline\fP as a line interface
for developing tcl scripts, you probably don't have to read
this section.

.PP
The following list will give all commands, which are currently
................................................................................

.TP 5
\fB::tclreadline::readline initialize\fP \fIhistoryfile\fP
initialize the tclreadline interface and read the history from
the \fIhistoryfile\fP. On succes 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.


.TP 5
\fB::tclreadline::readline write\fP \fIhistoryfile\fP
writes the history to the \fIhistoryfile\fP. This command is called
automatically from the internal routine ::tclreadline::Exit.

.TP 5
................................................................................
which will be displayed as the primary prompt. This prompt will be
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:
.EQ
    package require tclreadline
    namespace eval tclreadline {
        proc prompt1 {} {
            return "[clock format [clock seconds]]> "
        }
    }
    ::tclreadline::Loop
.EN

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.


.\".SH "EXAMPLES"


.\".SH "ENVIRONMENT VARIABLES"

.SH VARIABLES

The global variable \fBtclreadline_version\fP holds the version number
of the tclreadline package.

.SH FILES

the \fB.tclshrc\fP file in the HOME directory, which
is read on tclsh startup. Alternatively, the name of this initialization
file might be \fB.wishrc\fP ... depending on what interpreter you use.
These files should typically contain something like

.EQ
    if {$tcl_interactive} {
        package require tclreadline
        ::tclreadline::Loop
    }
.EN

which will enter the tclreadline main loop.

.PP
the \fB.tclsh-history\fP file in the HOME directory. On startup
commands will be read from this file. On exit, the readline history
is written to this file. Note that if you abort tclsh with <cntrl-c>
................................................................................
.PP
the \fB.inputrc\fP file in the users HOME directory. This file
is used normally for all programs which use the gnu readline (e.g.  bash).
The `global' readline settings there will be valid also for
\fBtclreadline\fP. Additionally the .inputrc might hold conditional
settings for the implementation name \fBtclreadline\fP. Example of 
some lines in your .inputrc:

.EQ
    $if tclreadline
    "\\C-xp": "puts $env(PATH)"
    $endif
.EN

For further documentation please refer to the gnu readline documentation.
