With the SWI-Prolog-Editor (Download Version 4.17 from 2013.11.16) a Windows-programming-environment for the work with SWI-Prolog which is suitable for schools has become available. The current version of the SWI-Prolog-Editor is tested for in lessons. In the documentation you find the most important information for work with the SWI-Prolog-Editor.
By means of language files the SWI-Prolog-Editor can be used with different languages. At present are available:

Installation of SWI-Prolog
Before the installation of SWI-Prolog-Editor you should install SWI-Prolog. You find the necessary programs and help-files on the SWI-Prolog Site.
You only can use the 32-Bit-Version of SWI-Prolog.
First install SWI-Prolog. In school-situations you should install SWI-Prolog on a server.
Then unzip the HTML-Manual of XPCE into the SWI-Prolog-directory /doc. During unzipping the corresponding folder UserGuide is automatically created.
Installation of SWI-Prolog-Editor
After the download of the SWI-Prolog-Editor you unzip the files into a temporary folder und execute the setup.exe program.
The installation-program has special support for school-situations. It is possible to install the SWI-Prolog-Editor local or on a server. You can choose the folder for installation
At the end of installation you execute SWI-Prolog-Editor to initialize the registry or INI-files. Control the configuration in menu Window|Configuration.
Installation on a server
First install SWI-Prolog-Editor from one client on the server. From each other client you start the setup-programm from the server and choose Connect to create a desktop-icon and an entry in the start menu.
Installation in INI-Files
If user-configurations can't be saved in the Windows-Registry because of protector-cards you install SWI-Prolog-Editor with INI-Files support.
With this type of installation the INI-file SWIMachine.INI is created in the installation-folder with the system-specific configuration in the tabsheets Program and Documentation. If SWI-Prolog-Editor recogniceses during startup this INI-File in it's start-folder, he uses the configuration from this INI-file instead from the Windows-Registry.
The user-specific configuration are stored in other folders in INI-files. I suggest to use the home-directories of the users, because there is write-access. The home-directory should be accessible on a local drive, by a mapped network drive or direct by UNC-folder-naming. If necessary you can use the variable %Username% in the destination folder for the user-specific folder.
After installation and configuration the administrator can set the INI-files in the installation-folder to read-only. So pupils cannot change configuration of the system-specific configuration.
For deinstallation you execute setup.exe in the installation-folder. After deinstalltion you manually delete setup.exe.
The SWI-Prolog-Editor also supports the XPCE-System, with which you can write Windows-Programs. In particular graphic outputs are possible. The following applications of the XPCE-Systems are offered:
SWI-Prolog is an outstanding Prolog-implementation of Jan Wielemaker. For use in school the console-mode isn't really suitable. The SWI-Prolog-Editor is a pupil-oriented and instruction-suited development environment for work with SWI-Prolog.
In the illustration you can see the program-window of the SWI-Prolog-Editor with menu- and symbol-border. In the left window the Prolog-program family.pl is loaded, the right window shows the contents of the SWI-Prolog-help.
Beneath is the SWI-Prolog-window, which currently is answering the question?- parent(X, maria).
The File-Menu has in addition to the standard-operations like new, open, save and print, the export-operation in HTML- and RTF-format. This enables pupils to use the syntaxhighlighting in their documentation and teachers to use it for classwork.
Edit-Menu and Editor-Symbols
The Editor supports the Windows-clipboard, search and replace functions with multilevel undo-facilities. Via symbols one can place and seek bookmarks, line-numbers are showed optionally. If the cursor is positioned direct in front of a bracket, you can jump with the bracket-symbol to the corresponding second bracket. Marked textblocks may be un-/indented, un-/commented or copied to the clipboard in text-, HTML- or RTF-format.
With the consult-operation of the Start-Menu or the corresponding symbol you can consult the prolog-program in the active window. With doubleclick on a error-message or -warning or with the context-menu of the SWI-Prolog-Window the cursor is positioned on the errorline in the sourcecode.
When dealing with a query the commands continue and cancel are activated. So you can ask for another solution or cancel the query.
If necessary one can start SWI-Prolog new via the command restart.
With the commands in the Test-Menu you execute a programm in trace-modus in steps, set or reset breakpoints and display the call-stack.
Besides the standard window-commands like arrange, open and close windows, you can choose the desired font and execute the configuration-facility:
The path to the SWI-Prolog-directory must be set. You do this by using the Select-button as the other paths will be are adjusted accordingly. Based on the Prolog-Folder the dependant documentation-directories will be determined.
Parameter is the command-line option for SWI-Prolog. By default 32 MB are reserved for the local stack.
Here you configure the directories for the commands in the Help-Menu.
You can also use the Online-Documentation:
For better performance the used documentation-files are cached, which means locally saved. By default as cache-folder C:Documents and Settings\Application DataSWI-Prolog-EditorCache is used.
The Tab width is adjustable. With activated Smarttabs the tab-key will automatically position the cursor at the next word-beginning of the previous line.
Indent is used for marked textblocks.
Autoindent places after pressing the return-key the cursor at the position of the first nonspace character of the previous line.
The Author will be automatically carried over if you create a new prolog-file.
With Encoding you set the default encoding of new source-files.
Under Structure you define how predicates, facts and rukes are shown in the file-structure.
On this tab you activate the code-completion and parameter-hints and define the delay in milliseconds. The code-completion is activated with the tab-key. It shows all predicates which start with the previously entered letters.
For code-completion the Prolog-Documentation must be installed.
Here you can configure the colors for the syntax-highlighting.
If you choose a syntax-element on the left side, it's color and textattributs are shown on the right. Click on the desired colors and textattributes. The button Standard resets all colors to the standard-colors.
If the internet-explorer is installed you can use it internally in SWI-Prolog-Editor to display the documentation.
If you wish to use the browser externally the functions of Browser-Title and Alt-Keys for "File open" in Browser are required. The SWI-Prolog-editor checks first whether the standard-browser is already loaded. To do this it uses the browser-titel, for example Netscape Navigator or Internet Explorer. If the standard-browser is already loaded, the HTML-file to be showed is placed in the addressfield of the command File open. To achieve this the File-Menu is activated with Alt-F und O chooses the open-command. So one needs FO in the corresponding input field.
Here you set the Printing-Parameters
Header and footer are separated in three sections, left, middle and right. The #-character is used for separating the sections. Besides fixed Text you can use the following variables to print some special elements:
|%PATH%||the filename inclusive the folder|
|%DATE%||the date of printing|
|%TIME%||the time of printing|
|%PAGECOUNT%||the total amount of pages|
Here you have some options
With the option Integrated SWI-Prolog-Window you can choose between the integrated or the original SWI-Prolog-Window.
With Return to continue you can use the return-key to ask for the next solution of your query. This is easier than the standard ";".
With this option the no-/trace-symbol also deactivates the debug-modus.
It is advised to activate .pl-files link with SWI-Prolog-Editor. So you can open pl-files in the windows-explorer with doubleclick.
At the ende you can choose a language-file.
The Help-Menu gives you access to the documentation of SWI-Prolog and XPCE. You can organize the help with own favorites.
If the cursor is placed over a predefined predicate the indexsearch F1 shows the corresponding description from the HTML-documentation.
The Editor is based on the SynEdit-Komponente. Besides the usual editor-functions it serves indent- and unindent of textblocks (shift+ctrl+I [indent] bzw. shift-ctrl-U [unindent]), delete line (ctrl+Y), delete to end of line (shift+ctrl+Y) and administration of ten bookmarks (set/delete shift+ctrl+#, jump ctrl+#). You can set and delete bookmarks directly in the bookmark-column.
