This is the follow-up to the "oorexx-packages" bundle that got introduced to the community about a
month ago.
This time the latest ooRexx, oorexxshell, oorexx-debugger, and - as a bit of surprise and favor to
the community - NetRexx is on board!
Needed steps: you download it, de-quarantine (see note # 1 below) the zip archive, unzip, and run
"setup," and off you go!
It cannot get easier for interested programmers, so there is no excuse for anyone not to check it
out as soon as possible!
Currently, the following 64-bit net-oo-rexx bundles are readily available for the most important
operating systems (in alphabetic order):
*
net-oo-rexx.macos.arm64-portable-release-20240724.zip
*
net-oo-rexx.macos.x86_64-portable-release-20240724.zip
*
net-oo-rexx.ubuntu2004.x86_64-portable-release-20240724.zip
*
net-oo-rexx.windows.x86_64-portable-release-20240724.zip
Here the temporary download link:
<https://wi.wu.ac.at/rgf/rexx/tmp/net-oo-rexx-packages/>
Here the content of the readme_net--oo-rexx.txt file:
"net-oo-rexx packages"
======================
This is the readme file for "net-oo-rexx", a bundling ready to use that
gives immediate access to a number of Rexx packages, like:
- bsf4oorexx (ooRexx-Java bridge for all operating systems) - dbus4oorexx
(ooRexx-DBus bridge
for Linux) - executor packages (see oorexxshell) - log4rexx (logging for
ooRexx) - netrexx (Java
in the clothes of Rexx) - nrws (NetRexx Workspace, a NetRexx shell) - oorexx
(open object Rexx)
- oorexxshell (a rexxtry.rex kind of shell for ooRexx) - regex (powerful
regular expression
implementation in ooRexx) - rexxdebugger (an ooRexx debugger, exploits the
Java bindings on Unix)
========================
Directions in a nutshell
========================
- download the latest "NetRexx, ooRexx with packages with oorexxshell"
(net-oo-rexx-packages) zip archive from
https://wi.wu.ac.at/rgf/rexx/tmp/net-oo-rexx-packages/
- de-quarantine the zip archive (see NOTE # 1 below)
- unzip the archive
- change into the unzipped directory and enter in the system shell
Windows Unix Comment
------- ---- +------
setup.cmd ./setup.sh | creates two scripts
This will create the two scripts:
run.cmd run | allows to run
net-oo-rexx programs
setenv.cmd setenv | allows to set
environment to net-oo-rexx in Terminal
----------------------------------------------------------------------------------------
---> use the generated 'run.cmd/run' script
Windows Unix Comment
------- ---- +------
run oorexxshell ./run oorexxshell | runs oorexxshell (a
script)
run rexx testoorexx.rex ./run rexx testoorexx.rex | use ooRexx to run
testoorexx.rex
run rexx which_rexx.rex | use ooRexx to run
which_rexx.rex
run nrc -exec which_rexx.rex | use NetRexx to run
which_rexx.rex
----------------------------------------------------------------------------------------
---> use the generated 'setenv.cmd/setenv' script
Windows Unix Comment
------- ---- +------
setenv.cmd source ./setenv | sets the environment
in the Terminal to net-oo-rexx
the following commands will work on Windows as well as on Unix:
oorexxshell | runs oorexxshell
rexx testoorexx.rex | use ooRexx to run
testoorexx.rex
rexx which_rexx.rex | use ooRexx to run
which_rexx.rex
rexxdebugger packages/rexxdebugger/tutorial.rex | use ooRexx to run the
rexxdebugger with its tutorial.rex
nrc -exec which_rexx.rex | use NetRexx to run
which_rexx.rex
nrc which_rexx.rex | use NetRexx to compile
which_rexx.rex to which_rexx.class
java which_rexx | use Java to run which_rexx.class
(note: no ".class" extension!)

Additional information
======================
To learn about the functionality of oorexxshell, take a few minutes and see
the
asciinema demos at [4].
First feedback
--------------
- "install this bundle, you run a small, trivial setup program, and, poof,
you have immediate access to a real trove of packages -- no additional
installation needed"
(JMB)
- "I even was able to load the JDOR handler, then "address JDOR", and then
construct one of the JDOR samples step-by-step, by manually writing the
(quoted) JDOR commands. This is very impressive, and very useful too,
from a pedagogical point of view, since it provides immediate incremental
visual feedback for the JDOR commands. You just have to move the Java
window besides the command window and you have a fantastic experience."
(JMB)

NOTES
=====
---------------------------------------
NOTE # 1: Microsoft and Apple do not allow programs from the Internet to run
if they are not signed using their fee-based service citing
"security
reasons".
Therefore, before installing or unzipping open source projects you
need
to "de-quarantine" (remove the respective attributes) the zip archives
before unzipping.
Windows: after downloading, open with a right-mouse click the property
menu, mark the "unblock" check mark and click "apply".
Thereafter you can install or unzip the file. Or open a
command line window and run (change 'filename' to the name of
the downloaded file):
powershell Unblock-File filename
e.g.,
powershell Unblock-File
net-oo-rexx.windows.x86_64-portable-release-20240707.zip
macOS: after downloading, open a Terminal window and run "xattr
filename"
to see the extended attributes of the downloaded file (replace
'filename' with the name of the zip archive), then issue
(again,
change 'filename' to the name of the downloaded file):
xattr -d com.apple.quarantine filename
e.g.,
xattr -d com.apple.quarantine
net-oo-rexx.macos.x86_64-portable-release-20240707.zip
---------------------------------------
NOTE # 2 for Unix versions.
In case the execution bit of shell scripts and executables got
removed,
run the supplied script makeAllExecutable.sh from the unzipped
directory:
sh ./makeAllExecutable.sh
---------------------------------------
NOTE # 3: Dual Installations (Linux & Windows)
You can use the same set of installed files to run the net-oo-rexx
bundle under both Windows and Linux, including the Windows
Subsystem
for Linux (WSL2) and other mechanisms like VirtualBox shared
folders.
Once you have run the necessary initializer scripts (setup.cmd
under
Windows, and ./setup under Linux/WSL), you will be able to use the
other scripts (run/setenv) under both operating systems. For
example,
you can test a program under Windows, then use the "wsl" command
to
switch to Ubuntu, and test the same program under Ubuntu, while
sharing
the same net-oo-rexx installation.
About WSL,
cf.<https://learn.microsoft.com/en-us/windows/wsl/about>
---------------------------------------
NOTE # 4: rerun the "setup.cmd" (Windows)/"setup" (Unix) script each time the
portable files get relocated or, if on a USB stick, each time you
plug in the USB stick. This will recreate on Windows the "run.cmd"
and "setenv.cmd" scripts, on Unix the "run" and "setenv" scripts,
thereby adjusting them to their new location.
---------------------------------------
NOTE # 5: bsf4oorexx (ooRexx-Java bridge)
In order to load and run bsf4oorexx programsyou need to have
Java/OpenJDK on your computer and either have PATH point to the
directory where the binary file java.exe (Windows)/java (Unix)
can be
found or set the environment variable JAVA_HOME to point to the
Java
home directory in which the Java subdirectories 'bin', 'lib' and
the
like are located.
You can download Java/OpenJDK from the Internet (usually for
free),
e.g., from Amazon, azul, bellsoft, IBM, Microsoft, ORACLE, SAP,
and
many more sites (all distributions use the same Java/OpenJDK
source
code).
Please make sure to pay attention to the following two important
points:
- download the "full version" respectively the version that
includes
"JavaFX", otherwise the interesting bsf4oorexx JavaFX samples
cannot
run
- download the Java/OpenJDK version matching your operating system
and the machine type of your computer, e.g., a 64-bit Intel
(machine
type "x86_64") Windows version download the "x86_64" (Intel,
AMD)
Windows Java/OpenJDK installation package or zip archive. If you
use macOS or Linux then download the respective full
Java/OpenJDK
versions.
It is possible to have different versions of Java/OpenJDK present
on
your computer at the same time. The environment variable JAVA_HOME
can then be used to point to the Java/OpenJDK directory that you
wish
to use in your current session/terminal/command line window. This
way
you can develop and test bsf4oorexx programs for different
versions
of Java/OpenJDK on the same computer.
To see what becomes possible with bsf4oorexx, check out the
samples
in packages/bsf4oorexx/samples which all get briefly described in
the
index.html file located there as well.
bsf4oorexx programs can be executed directly with rexx[.exe] or
via
Java using the shell scripts "rexxjh.cmd" (Windows)/"rexxjh.sh"
(Unix),
e.g.,
cd packages/bsf4oorexx/samples
rexxjh.cmd 1-040_list_charsets.rxj -- Windows: Java loads
ooRexx to run script
rexxjh.sh 1-040_list_charsets.rxj -- Unix: Java loads
ooRexx to run script;
rexx 1-040_list_charsets.rxj -- Rexx loads Java to
run script
Apple users please note: if running any bsf4oorexx script that
creates a GUI, then
you must use the scripts rexxjh.sh to run them.
