All-
This is to announce an improved perldl2 experiment
in the latest PDL git. Look in the PDL/Padre directory.
The README file there has instructions for installation
and use. It is still very rough around the edges but
getting closer to being usable in place of the perldl
shell. Work continues on compatibility and portability
problems on win32. Feedback welcome!
Enjoy,
Chris

** This is experimental code so use at your own risk! **
This directory contains on-going development efforts for
getting PDL to work with Padre. We are starting with
implementing a new, improved perldl shell (e.g. perldl2)
using Devel::REPL as the starting point. Since that
same Devel::REPL is the basis of the Padre REPL module
Padre::Plugin::REPL, it is hoped that this will simplify
future Padre+PDL development.
You will need to install the version 1.3.9+ of Devel::REPL
in addition to PDL to use this code. A description of the
files included and how to install and use them follows.
FILES:
NiceSlice.pm
Implements PDL::NiceSlice preprocessing for the Devel::REPL
shell (i.e. Devel::REPL::Plugin::NiceSlice) for perldl2.
Perldl2.pm
The perldl2 profile for use with the Devel::REPL shell.
README
This file.
INSTALL:
The installation is manual at this time. Simply copy
NiceSlice.pm to the Devel/REPL/Plugin/ directory of your
Devel::REPL install and copy Perldl2.pm to the
Devel/REPL/Profile directory of the Devel::REPL install.
USE:
To try/use the experimental perldl2 shell, just run the
following command from the shell prompt:
re.pl --profile Perldl2 # for unix/linux/mac os x
re --profile Perldl2 # for win32 systems
Set the DEVEL_REPL_PROFILE environment variable to
Perldl2 and you should just be able to run re.pl or
re to get going.
To exit the perldl2 shell, type Ctrl-C, Ctrl-D or exit.
NOTES:
Supported functionality from Devel::REPL and PDL:
* History (redo commands with !-1 and !## syntax)
* LexEnv (e.g., my $a = zeros(10) works)
* DDS (pretty prints output using Data::Dump::Streamer)
* Packages (keeps track of user package)
* Commands (generic command creation)
* MultiLine::PPI (handles multiline input like perldl)
* NiceSlice (PDL::NiceSlice works too!)
* CompletionDriver::Methods (TAB completion of method names)
* CompletionDriver::INC (TAB completion for use module..)
Default PDL modules loaded:
* PDL
* PDL::Dbg
* PDL::Doc::Perldl
* PDL::IO::Dumper
* PDL::IO::FlexRaw
* PDL::IO::Pic
* PDL::Image2D
* PDL::AutoLoader
Completion doesn't work for win32 because no GNU readline.
use strict on by default
edit the Perldl2.pm file to add additional default setup
for the perldl2 shell. You can $repl->eval() anything
you want before the shell starts. The other thing is
to $repl->load_plugin() if you wish to try additional
Devel::REPL plugins.
help, apropos work but
* ? and ?? aliases don't work
* you need to quote the arguments
All results are printed by default so big piddle output
can be problematic. Work is underway to fix this.
