Rebol for Linux 64bit

Wow, Rebol is released also for Linux 64bit: http://www.rebol.com/downloads.html

Linux packages renewed

I received a message complaining about  a message "Packet is of bad quality" installing my packages.
Well, using lintian, a software checking the quality of debian packages, I updated the Rebol 2 linux packages here:
http://www.maxvessi.net/rebsite/linux/
and here:
https://github.com/angerangel/Rebol-linux-packages

Please let me know if you have some problems about the packages.
Do you want also Rebol 3 packages?

Linux packages

I created some time ago the Linux auto installation packages, some people asked me how, so I decide to put all needed files on Github.
Github link is the following: https://github.com/angerangel/Rebol-linux-packages
How to make a Linux package?
It's very simple:

• first of all you need to create a directory with you package name (for example "rebol")
• inside this folder you must put the folders that you want to install in pc, the same structure parting from "/" (the roo folder). In my case I needed to copy rebol intepreter in "/usr/bin" and something else in "/usr/share/". So this is my directory structure:
  
  
• As you probably noticed, I also created a "DEBIAN" directory, this is requested by .deb package format. Inside the DEBIAN directory you must put a "control" file. This is my control file:
  
Package: rebol
Version: 2.7.8.4.3
Architecture: i386
Installed-Size: 1175
Section: devel
Priority: optional
Homepage: http://www.rebol.com
Depends: libc6, libstdc++6, libx11-6, libxcb1, libxaw7, libfreetype6, libxext6, libxt6, libxmu6, libgcc1, libsm6, libice6, libxpm4, zlib1g, libxau6, libxdmcp6, libuuid1, xfonts-100dpi, xfonts-75dpi
postinst: mandb; update-app-install
Maintainer: Massimiliano Vessi <maxint@tiscali.it>
Description: REBOL stands for relative expression based object language.
Software systems have become too complex,
layers upon layers of complexity, each more brittle and
vulnerable to failure. In the end software becomes the
problem, not the solution. We rebel against such complexity,
fighting back with the most powerful tool available:
language itself.
.
This package contains the REBOL/View 2.7.8.4.3 binary

• Then I added the man pages
• Then I added the icon to display in the application menu, in "/usr/share/pixmaps/"
• Then I wrote the rebol.desktop, a file that add rebol in the application panel like this:
  
  
  to obtain this result, I wrote the file this way:
  [Desktop Entry]
X-AppInstall-Package=rebol
X-AppInstall-Proprietary=true
X-AppInstall-Architectures=i386;amd64
Encoding=UTF-8
Name=Rebol
Icon=rebol-icon
Terminal=true
Type=Application
Categories=Application;Development;IDE;
StartupNotify=true
MimeType=text/r;
Exec=rebol
Comment=Programming is fun again
  terminal=true is important to start rebol from a terminal, or you won't see console.
•  Now you must have alien installed, in order to convert the debian package in other formats (RPM, tar.gz, etc.)
• Launch my script (packcreator.sh) and you'll obtain all packages for all linux platforms. My script is very simple:
  #!/bin/bash
#removing old versions
rm rebol*.deb
rm rebol*.tgz
rm rebol*.rpm
#creating new ones
dpkg-deb -b rebol
dpkg-deb -b rebol_amd64
sudo alien --to-rpm --to-tgz rebol.deb
sudo alien --to-rpm rebol_amd64.deb

New linux auto installer packages are ready to download:

http://www.maxvessi.net/rebsite/Linux/

Do you want an HTML dialect to biuld html pages? Here it’s ready:

http://97.107.135.89/www.hmkdesign.dk/project.rsp?id=html-dialect&page=docs

One liner of the week:

view f: layout for n 0 19 1[r:(random 19)+ n // 20 append[across]load rejoin["a"n": check on[a"r"/data: a"r"/data xor on show f]"]]

It’s a game: line of twenty boxes appear, each with a cross on, the object being to remove all the crosses. Clicking on a box will toggle it and one other off and on.
