tclreadline


1. Introduction
---------------

    (c) The usual ./configure; make; make install sequence should do the rest.

    (d) Optionally (or additionally) you can build the executables
        tclshrl and / or wishrl which are a readline enhanced replacement
        for tclsh and wish. To compile these executable you should type

        ./configure --enable-tclshrl --enable-wishrl

    (or one of these if you want just tclshrl or wishrl).
    NOTE that these executables need an installed version of
    tclreadline because they need some script files to run
    so you can't test tclshrl/wishrl before installing
    the tclreadline scripts.

        Building statically linked executables is DISCOURAGED
    but necessary on systems which don't support shared libs.


4. Using tclreadline for interactive tcl scripting.
---------------------------------------------------

copy the sample.tclshrc to $HOME/.tclshrc. If you use another interpreter
like wish, you should copy the file sample.tclshrc to $HOME/.wishrc
(or whatever the manual page of your interpreter says.) If you have
installed tclreadline properly, you are just ready to start:
start your favorite interpreter. The tclreadlineSetup.tcl script
does the rest.


4. History and Changes.
-----------------------

tclreadline-1.2 0: (Mar 2000)
    switched to a BSD type license, introduced a new read-only
    variable `license' in the tclreadline namespace.

tclreadline-1.1 0: (Mar 2000)
    code cleanup and checked that it compiles with tcl8.3

tclreadline-1.0.1: (Sep 1999)

    changes:
        - tclreadline::readline bell.
          Ring the terminal bell, obeying the setting
          of bell-style -- audible or visible.


tclreadline-1.0.0: (Sep 1999)

    note:
        - the script completer procs are written.
          this is `sort of a first usable release'.

    fixes:
        - some minor configure.in fixes.


tclreadline-0.9.3: (Sep 1999)

    changes:
        - tk completion.
        - multiple fallback completion routines for unknown
          commands.
        - readline reset-terminal sub-function.

    fixes:
        - another revision of procession events and macros.
          includes a hack using a readline's internal
          variable _rl_executing_macro.


tclreadline-0.9.2: (Aug 1999)

    changes:
        - history event `!' expansion on <Tab>
        - if tclreadline::historyLength >= 0,

        - tclreadline::readline customcompleter
        - tclreadline::readline builtincompleter
        - tclreadline::readline eofchar
        - variable, array and '[' command completion by the script
          tclreadline::ScriptCompleter. See the man page or try
          typing "puts $env<TAB>" ... Command completion currently only
          works, if a '[' preceeds immediately a non-white character.
        - the redefinition of the command `cd' was removed due to
          multiple requests. This redefinition can be found in the
          file `sample.tclshrc' and can be uncommented, if desired.
        - the definition of the command `ls' was moved outside the
          proc tclreadline::Setup and can be used with the command
          namespace import tclreadline::ls (see sample.tclshrc).

    bug fixes:
        - lines added to tcl's history. (were only in readline's hist.)
        - macro mappings didn't work. (only when hitting

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

arguments, it returns the current setting.

.TP 5
\fB::tclreadline::Loop\fP [\fIhistoryfile\fP]
enter the tclreadline main loop. This command is typically called from
the startup resource file (something .tclshrc, depending on the interpreter
you use, see the file `sample.tclshrc'). The main loop sets up some
completion characteristics as variable -- try something like "puts $b<TAB>" --
and command completion -- try "puts [in<TAB>".
If the optional argument \fIhistoryfile\fP is given, this file will
be used for reading and writing the command history instead of the
default \fB.tclsh-history\fP.
\fB::tclreadline::Loop\fP will normally not return.
If you want to write your own main loop and/or own custom completers,
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

handler, which will write the history on <ctrl-c> before exiting.

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