>Description:
JLine is a Java library for handling console input. It is similar in
functionality to BSD editline and GNU readline. People familiar with
the readline/editline capabilities for modern shells (such as bash and
tcsh) will find most of the command editing features of JLine to be
familiar.
JLine is distributed under the BSD license, meaning that you are
completely free to redistribute, modify, or sell it with almost no
restrictions.
API documentation can be found in the apidocs directory.
You can use the jline.ConsoleRunner application to set up the system
input stream and continue on the launch another program. For example,
to use JLine as the input handler for the popular BeanShell console
application, you can run: java jline.ConsoleRunner bsh.Interpreter

X# TAB-Completion for Jython with JLine console.
X# JLineCompleter.py,v 1.4 2007/09/26 11:57:31 martin Exp
X
X# Jython + JLine + Tab-Completion Micro-Howto:
X#
X# JLine is a 99% pure Java console library similar to GNU Readline but
X# with an incompatible API. Jython 2.2 already contains some support
X# for JLine. For basic line editing and a command history it suffices
X# to set python.console=org.python.util.JLineConsole either in the
X# Jython registry or in the ~/.jython file. Obviously the JLine
X# jarfile must be in your classpath.
X#
X# Unfortunately Jython does not support tab-completion for JLine yet.
X# It can be enabled by importing this file - however this needs
X# patches. To summarize prerequisites:
X#
X# 1. You need a patch to JLine that adds the
X# ConsoleRunner.getReader() method. On FreeBSD build jline with
X# option WITH_JLINEPATCH enabled.
X#
X# 2. You must wrap the entry point to Jython with a
X# jline.ConsoleRunner instance. You do this by editing
X# /usr/local/bin/jython and inserting an extra argument
X# "jline.ConsoleRunner" right before the "org.python.util.jython"
X# argument.
X#
X# 3. While there don't forget to add
X# /usr/local/share/java/classes/jline.jar to the classpath.
X#
X# 4. You must set python.console="" in the ~/.jython file. You
X# don't want Jython to create another console instance running
X# behind the wrapper console.
X#
X# 5. Finally you have to import this module. You may want to do a
X# "import user" instead and code the "import JLineCompleter"
X# inside ~/.pythonrc.py instead.
X#
X# If that is too much hassle - just wait for my upcoming
X# devel/libreadline-java port!

X
X"""Word completion for JLine
X
XThe completer completes keywords, built-ins and globals in a
Xselectable namespace (which defaults to __main__); when completing
XNAME.NAME..., it evaluates (!) the expression up to the last dot and
Xcompletes its attributes.
X
XIt's very cool to do "import sys" type "sys.", hit the
Xcompletion key (twice), and see the list of names defined by the
Xsys module!
X
XTip: to use the tab key as the completion key, call
X
X readline.parse_and_bind("tab: complete")
X
XNotes:
X
X- Exceptions raised by the completer function are *ignored* (and
Xgenerally cause the completion to fail). This is a feature -- since
Xreadline sets the tty device in raw (or cbreak) mode, printing a
Xtraceback wouldn't work well without some complicated hoopla to save,
Xreset and restore the tty state.
X
X- The evaluation of the NAME.NAME... form may cause arbitrary
Xapplication defined code to be executed if an object with a
X__getattr__ hook is found. Since it is the responsibility of the
Xapplication (or the user) to enable this feature, I consider this an
Xacceptable risk. More complicated expressions (e.g. function calls or
Xindexing operations) are *not* evaluated.
X
XThis module is a slightly hacked version of the CPython 2.5 module
Xrlcompleter. It is therefore under the PSF (Python Software
XFoundation) license.
