================================================================ Logtalk - Open source object-oriented logic programming language Release 2.30.7 Copyright (c) 1998-2007 Paulo Moura. All Rights Reserved. ================================================================ This folder contains supporting files for converting and/or indexing XML documentation files (which are created when compiling objects, categories, or protocols) to PDF files or (X)HTML files using XSL style sheets. The documentation files may also be viewed directly on a web browser that supports the W3C standards XML, XSLT, CSS, and HTML 4 or XHTML 1.0. The shell and command-line scripts should be called from the directory containing the XML documenting files that you wish to convert. See the description of each script below for details. MAKE SURE THAT THE XSL PROCESSORS YOU INTEND TO USE ARE PROPERLY INSTALLED AND WORKING BEFORE RUNNING THESE SCRIPTS! Regarding conversion to (X)HTML, the links to the XSL files on the XML files and the links to the CSS files in the generated HTML files assume that all files reside in the same directory. The choice of the default XSL file to use is made in the config files by the '$lgt_default_flag'/2 predicate. You may also choose a different XSL file by using the xslfile/1 compiler flag in the logtalk_compile/2 or logtalk_load/2 calls. The default file is "lgtxml.xsl" (described below). The documenting files can be generated either as standalone XML files or contain a reference to either the Logtalk DTD file, "logtalk.dtd", or to the Logtalk XML Schema file, "logtalk.xsd". The reference to the XML specificationfile can be either a local reference or a URI reference. By default, all XML documenting files contain a local reference but that can be changed either in the config files, by setting a Logtalk compiler flag, or by using the xmlsref/1 compiler flag. Choose the option value that works best with your XSLT tools. To choose between the DTD or XSD specifications use the xmlspec/1 compiler flag. As Logtalk uses a single namespace for all objects, categories, and protocols, you may want to define an alternate, global compilation directory to store all the XML documenting files, thus ensuring proper working of links to other entities in the generated (X)HTML files. This can be easily accomplished by using the predicate '$lgt_default_flag'/2, which is defined on the config files. For example: '$lgt_default_flag'(xmldir, 'xml_docs/'). ... '$lgt_default_flag'(altdirs, on). ... Brief description of each file in this folder: lgtxml.xsl XSLT file for viewing XML files directly in a browser. The links in the (internally generated) HTML 4.01 files point to related XML files. UTF-8 encoding is assumed. Edit the file if you use a different encoding. lgthtml.xsl XSLT file to output HTML 4.01 files from the XML files. The links in the generated HTML files point to related HTML files. It can be used to batch convert XML files to HTML files. UTF-8 encoding is assumed. Edit the file if you use a different encoding. lgtxhtml.xsl XSLT file to output XHTML 1.1 files from the XML files. The links in the generated XHTML files point to related XHTML files. It can be used to batch convert XML files to XHTML files. UTF-8 encoding is assumed. Edit the file if you use a different encoding. lgtpdf.xsl lgtpdfa4.xsl lgtpdfus.xsl XSLT files to generate PDF files from the XML files (formatted either for A4 paper or US Letter paper) using XSL Formatting Objects. Tested with the XSL-FO processors Apache FOP 0.20.5 (http://xml.apache.org/fop) and RenderX 4.4 (http://www.renderx.com/). The "lgtpdf.xsl" file defines a parameter for the paper format (either A4 or US Letter). The files "lgtpdfa4.xsl" and "lgtpdfus.xsl" import the "lgtpdf.xsl" file and set the paper format parameter to the appropriate value. ie50.xsl XSLT file for viewing XML files in Microsoft Internet Explorer 5.x (using the outdated Microsoft XML Parser; works with both Macintosh and Windows versions). The links in the (internally generated) HTML files point to related XML files. It can be used to browse and view the XML files directly. logtalk.dtd DTD file describing the structure of the XML files generated by Logtalk. custom.ent Document type description defining XML entities for personal data that may be used on Logtalk documenting directives. logtalk.rng RELAX NG file describing the structure of the XML files generated by Logtalk. logtalk.xsd XML Schema file describing the structure of the XML files generated by Logtalk. logtalk.css Cascade style sheet file to render the HTML/XHTML output of the XSL files in a web browser. lgt2pdf.sh (bash shell script) lgt2pdf.js (JScript command-line script for Windows; requires WSH 5.6 or later version) Sample scripts to batch convert XML files to PDF files Supported XSL-FO processors: * Apache FOP processor (tested with version 0.20.5) http://xml.apache.org/fop * Lunasil Xinc processor (tested with version 2.02) http://www.lunasil.com/index.html * RenderX XEP processor (tested with version 3.8.1) http://www.renderx.com/ When using the FOP, you must compile your Logtalk source files using the compiler option xmlsref(standalone) in order to workaround a bug on the XALAN processor used by this processor. These script assume that the LOGTALKHOME and LOGTALKUSER environment variables are defined and that the chosen XSL-FO processor is available in the path. The scripts should be called from the directory containing the XML files you wish to convert. Call the scripts with the help option for a description of the available optional parameters (type "cscript lgt2pdf.js help" or "lgt2pdf.sh -h"; depending on your Logtalk installation, you may simply need to type "lgt2pdf" in order to run the script). lgt2html.sh (bash shell script) lgt2html.js (JScript command-line script for Windows; requires WSH 5.6 or later version) Sample scripts to batch convert XML files to HTML files. These scripts also generate an "index.html" file which contains links to all the converted files. Supported XSLT processors: * libxslt (tested with version 1.1.8) http://xmlsoft.org/XSLT/ * Xalan (tested with version 1.7.0) http://xml.apache.org/xalan-c/index.html * Sablotron (tested with version 1.0.1) http://www.gingerall.com/charlie/ga/xml/p_sab.xml * Microsoft MSXSL (only for the Windows JScript script) http://msdn.microsoft.com/XML/XMLDownloads/default.aspx These scripts assumes that the LOGTALKHOME and LOGTALKUSER environment variables are defined and that the chosen XSLT processor is available in the path. The scripts should be called from the directory containing the XML files you wish to convert. Call the scripts with the help option for a description of the available optional parameters (type "cscript lgt2html.js help" or "lgt2html.sh -h"; depending on your Logtalk installation, you may simply need to type "lgt2html" in order to run the script). lgt2xml.sh (bash shell script) lgt2xml.js (JScript command-line script for Windows; requires WSH 5.6 or later version) Sample scripts for indexing the XML files in the current directory by generating an index.html file which contains links to all the files. In addition, these scripts also copies of the "lgtxml.xsl" and "logtalk.css" files to the current directory, allowing direct visualization of the XML files on a supported web browser. These scripts assumes that the LOGTALKHOME and LOGTALKUSER environment variables are defined. The scripts should be called from the directory containing the XML files you wish to index. Call the scripts with the help option for a description of the available optional parameters (type "cscript lgt2xml.js help" or "lgt2xml.sh -h"; depending on your Logtalk installation, you may simply need to type "lgt2xml" in order to run the script). Note that you can write other XSL files for converting the XML files to other formats besides PDF or (X)HTML. You can also write alternative CSS and XSL files to change the appearance of the (X)HTML and PDF files.
