tclreadline
1. Introduction
---------------
This directory contains the sources and documentation for tclreadline,
which builds a connection between tcl and the gnu readline.
The information here corresponds to release 0.9.
2. Documentation
----------------
The tclreadline.n nroff man page in this release contains the reference
manual entries for tclreadline. If you only want to use tclreadline as
a tool for interactive script development, you don't have to read this
manual page at all. Simply change your .tclshrc according to the section 4.
3. Compiling and installing tclreadline
---------------------------------------
This release will probably only build under UNIX (Linux).
Before trying to compile tclreadline you should do the following things:
(a) Make sure you have tcl 8.0 or higher. I've tested tclreadline
with tcl 8.0.3, 8.0.4, 8.0.5, 8.1.0, 8.1.1 and 8.2.0.
tclreadline relies on a proper tcl installation:
It uses the tclConfig.sh file, which should reside somewhere
in /usr/local/lib/ or /usr/local/lib/tcl8.0/...
(b) Make sure you have gnu readline 2.2 or higher.
tclreadline uses the gnu readline callback handler, which
wasn't implemented in early releases.
The usual ./configure; make; make install sequence should do the rest.
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-0.9: (Aug 1999)
changes:
- 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
mapped characters more than once.)
- various changes and fixes in configure.in
tclreadline-0.8: (May 1999)
- adapted for tcl8.1.
- minor bug fixes.
tclreadline-0.7: (Mar 1999)
first `public release'.
