Free wg software for linux

W2g is a framework for building Web-based applications such as online databases, intranet portals, or CRM systems.

W2g applications are developed within the web browser, no coding is needed. However, if you are a programmer, you can extend the multi-faced feature set of W2g even more. Skel files can be filled with custom code that replaces or extends W2g standard functions.

W2g is written in Perl and is working completely as Apache module. Code gets compiled only once, then executed from Apaches internal cache - including custom Perl code inserted in one of W2gs auto-generated, module-specific skel files.

Wg uses MySQL as database backend. W2g is optimized for speed. Various internal caching features prevent fetching redundant information from the database.

W2g is open-source. It is licensed under the GNU GPL.

Graffiti Server is a small C program that allows the posting of messages and, optionally, HTML. It displays the most recent messages but has a search function for finding entries with a given keyword or string.

The administrator connects from the local host using IP address 127.0.0.1 and delete messages from any IP.

You can search for any text string and the graffiti server will match against all old messages, as well as new ones, and return those that match.

Right click here and select save... to download a gzipped Linux binary. Right click here for the gzipped source for the graffiti server. The binary is only 45K[2] bytes and the source is only 9K in size (compressed).

To install it, simply gunzip the binary and run it with one of the following commands, then install the same command in your startup files. For example, in many Linuxes, you can put the command in /etc/rc.d/rc.local and it will be executed on each startup.

The general syntax is:

graffiti [port] [directory] [!]

The first argument is the port. If there is only one argument, it must be a port number.

The second argument is a directory name.

The third argument, if present and an exclamation point (!) tells graffiti to allow html postings.

Command examples:

graffiti

(The above will attempt to use port 80, the standard WWW port, will put its files in /var/tmp/ and will disallow html.)

graffiti 7777

(This command will do everything just like the command before it, only it will attempt to use port 7777 instead of 80.)

graffiti 8888 /home/rayy/graffiti/

(This command will put the files in /home/rayy/graffiti/ and will try to run on port 8888.)

graffiti 9999 /home/rayy/graffiti/ !

(This one will, again, put the files in /home/rayy/graffiti but will use port 9999, and will allow html entries.)

The data files take about 1 megabyte but will hold about 2500 graffiti entries, as configured.

If a file named wg####.txt is present in the data files directory, the Graffiti Server will display that file on every page. [Where #### is the port number the Graffiti Server is running on]. You can run as many copies of the graffiti server as you wish on separate ports. Because each copy puts its port number in its file names, there will be no file conflicts.]

ubuildinit is a utility for use with micro window-gadgets (UWG) that generates C source and header files from XML descriptions of visual interfaces.

Interfaces are described using XHPD, an XML-based hierarchical program description.

Micro WG is a C `version of WG. In general, UWG is somewhat more light-weight than WG. Firstly because its written in C and not C++. Secondly because it does not yet provide all the features of WG. Also, it should be significantly easier to `connect UWG to KRoC.

Why UWG ? Its now the case that there are many `widget libraries for programmers to choose from. The traditional X11 widget libraries (X Toolkit Intrinsics), GTK, QT, Motif, wxWindows, TK, etc.. GTK and QT are probably the most common for an average users desktop system -- as the graphics libraries of Gnome and KDE respectively. C++, used by WG, provides a largely type-safe environment for gadget programming -- i.e. the structure/nature of gadgets fit neatly into the C++ type (class) heirarchy.

However, C++ ultimately suffers from the same problems as some other `object-orientated languages -- namely leaky encapsulation. When writing WG, some of the limitations (maybe features) of C++ caused significant problems, particularly in the function-pointer department.

Object-orientation is a fine model for data, but it does not work well when `bolted-on to sequential languages -- C++ and Java in particular. Forcing a sequential flow-of-control through something that we tried to break into objects only leads to problems. E.g. when executing inside the method of one object, is it safe to delete another object ? -- well, only if that other object wasnt involved (and still is involved) in the flow-of-control.

And this you cannot easily tell. Furthermore, in many cases, `delete may be substituted for any object interaction (method-call).

Also, a lot of modern GUI toolkits seem unnecessarily bloated. C++ (and other `frilly languages) can be blamed for some of this, but not all of it. WG isnt bloated yet, but its not far off. UWG is therefore an attempt at a lightweight (size and speed) gadget toolkit for X11, programmed in C.
