vol-0 - afnix installation guide


This chapter describes the installation procedures for the AFNIX writing system distribu‐ tion. This chapter explains how to set and compile this distribution. Software distribution The complete distribution can be downloaded from the AFNIX home page. The result is a com‐ plete source tree that is ready for compilation. The distribution contains also the docu‐ mentation as well as examples. The distribution is supported on a variety of platforms as indicated below that can be either 32 bits or 64 bits machines. The distribution is also available at the FreeBSD port collection. Platform Processor Operating system Linux X86-32, X86-64, IA64, SPARC-32, SPARC-64 Linux 3.x, 4.x FreeBSD X86-32, X86-64, IA-64, SPARC-32, SPARC-64 FreeBSD 8.x, 9.x, 10.x.x Gnu X86-32, X86-64 GNU KBSD, GNU Hurd Specific processors like the Alpha, M68K, ARM, MIPS and SUPERH are also supported on cer‐ tain distributions. The PowerPC (PPC) processor has been discontinued. The Solaris SPARC platform has been discontinued. Do not hesitate to contact the development team for spe‐ cific processor or platform support. Installation procedure The core software is written in C++. It has been successfully built with the GNU GCC 4, 5, 6. The clangcompiler has also been succesfully tested. You will also need the GNU Makepackage. With some distributions the command is called gmake. Note that the Makefile‐ hierarchy is designed to operate safely with the -jGNU Makeoption. Unpacking the distribution The distribution is available as a compressed tar file. Note that the documentation is distributed in a separate file. The following command unpacks the distribution. zsh> gzip -d afnix-src-[version].tar.gz zsh> tar xf afnix-src-[version].tar Quick command reference The list of commands to execute is given in the example below. A detailed description for each command is given hereafter. The make worldcommand is the default command that builds the whole tree with the default compiler. zsh> ./cnf/bin/afnix-setup -o --prefix=/usr/local/afnix zsh> make status zsh> make [-j] zsh> make test zsh> make install zsh> make clean With some platforms, the makecommand should be replaced by the gmakecommand. The make sta‐ tuscommand is optional and can be used to report the internal value contents. In particu‐ lar, the version and the installation parameters are reported. Configuration The afnix-setupcommand can be invoked to setup a particular configuration. You should have your compiler on your search path. Normally, the command given below is enough. zsh> ./cnf/bin/afnix-setup -o --prefix=/usr/local/afnix This command checks that the target platform can be detected and configured. The -ooption configures the compilation in optimized mode. Use the -goption can be used to configure the build process in debug mode. The --prefixoption sets the installation directory. Note that the compilation process is done in the distribution tree and that the --prefixoption affects only the installation operations. The -voption is the verbose option. Other options are available for fine tuning. Option Description Default -h Print a help message n/a -v Set the verbose mode n/a -g Set the debug mode yes -o Set the optimized mode no --help Same as -h n/a --prefix Set the target install directory /usr/local --shrdir Set the shared install directory /usr/local/share --altdir Set the alternate install directory /usr/local --sdkdir Set the system kit directory platform dependent --compiler Set the default compiler platform dependent --proctype Set the processor type generic --dynamic Compile and link dynamically yes --static Compile and link statically no --openmp Enable the optional openmp compilation no The prefixoption set the root installation directory. The binary and library installation directories are derived from it. The shrdirset the shared installation directory which is normally used for the installation of the manual pages on most popular systems. the alt‐ dirsets the alternate installation directory. Normally this path should be empty as it affects the path for the etcdirectory. This flag should be used when using a prefix to unusual destination. the sdkdiroption sets the path of the platform system development kit. This option is only used with the Darwinplatform. The compileroption can be used to force a particular compiler with the help of a compiler configuration file. The proctype‐ option can be used to force a particular processor architecture. The -sor --staticoption can be used to build a static executable. Normally, this option should not be used since it restrict the use of extension modules. The dynamiccontrols whether or not the dynamic libraries should be built. This option is detected automatically for a particular platform and should be used only by package maintainer. There exists also specific options which are mostly for package maintainers. At this time, the build process integrates the Debian, Ubuntu and Fedora specific packaging mechanism. Option Description Default --package Set the type of package to support none --pkgbin Set the optional package bin directory none --pkglib Set the optional package lib directory none --pkgprj Set the optional package project directory none --pkghdr Set the optional package header directory none --pkgetc Set the optional package etc directory none --pkgman Set the optional package manual directory none --pkgdoc Set the optional package documentation directory none --pkgwww Set the optional package www directory none Compiling the distribution The compilation process is straightforward. With some platforms, the makeaccepts the -jthat enables concurrent operations. zsh> make [-j] This will build the complete distribution locally. If an error occurs, it is best to report it at the ( AFNIX bug reportmail address. Testing the distribution The distribution contains all test suites. The test suites are compiled and executed with the following command. zsh> make test This command run the test suites for each library as well as the test suites for each application client. Most of the base library test suites are written in C++ with the application test suites written in the core writing system. Installing the distribution Once the system has been built and tested, it can be installed. By default, the distribu‐ tion tree is installed into the /usr/localdirectory. This can be overwritten with the --prefixoption during the configuration process. zsh> make install There are several variables that controls the behavior of the installrule. Each variable has its default value sets during the setup configuration. However, this variable can also be altered during the installation process Variable Description Default PREFIX The root install directory /usr/local SHRDIR The shared install directory /usr/local/share ALTDIR The shared alternate directory /usr/local/etc SDKDIR The system kit directory platform dependent BINDIR The binary install directory prefix/bin LIBDIR The library install directory prefix/lib HDRDIR The header files install directory prefix/include/afnix ETCDIR The extra files install directory altdir/etc/afnix Installing the documentation The documentation is installed independently of the software. The docrule builds the docu‐ mentation and the publishrule installs the documentation. Several variables also control the documentation installation path. Variable Description Default DOCDIR The documentation install directory shrdir/doc/afnix MANDIR The manual pages install directory shrdir/man Cleaning the distribution The distribution is cleaned with the cleanrule. zsh> make clean This rule does not clean the configuration. For a complete cleaning the resetrule is more appropriate. zsh> make reset Running AFNIX The axicommand invokes the interpreter. In order to operate properly, the LD_LIBRARY_PATHenvironment variable must be configured with the directory containing the shared libraries. If the libraries have been installed in a standard location like /usr/local/lib, there is nothing to do. Running some example The directory expcontains various examples which can be run. Each example is labeled according to their use in the volume 1 of the documentation set. Example 0101.alsprints the message hello world. Example 0501.alsprints various information about the system con‐ figuration. zsh> axi 0501 major version number : 2 minor version number : 8 patch version number : 0 interpreter version : 2.8.0 operating system name : linux operating system type : unix afnix official uri : Special features The build process provides several features that permits to customize the compilation process as well as the nature of the final executable. Most of the time, these options are reserved for the package maintainer and are given below for illustration purpose. Target customization The distribution can be configured to operate on a specific machine target. For example, a typical Linux box will be compiled with the default compiler target, which is the 386 pro‐ cessor. You can force the compilation to be optimized for a particular processor. This is done with the --proctypeoption of the afnix-setupcommand. Currently the distribution sup‐ ports the 586and 686architectures for the Intel platform. The ultraarchitecture is valid for the SPARC platform. zsh> cnf/bin/afnix-setup -o --prefix=/usr/local --proctype=586 This command will configure the distribution to be compiled specifically for the Pentium architecture. Special target extensions Extensions are specific libraries or executables which are not build automatically during the build process. The user is responsible to decide which extension is needed for the system All extensions are located under the src/extdirectory. Simply going into the appro‐ priate directory and running the makecommand will build the extension. The asiextension creates a static interpreter with all libraries automatically included in the final exe‐ cutable. The extension is simply build with the following command. Note that this exten‐ sion overwrite the previous executable in the bld/bindirectory. zsh> make -C src/ext/asi Extra files The distribution comes with some extra files. The most important is the Emacs mode afnix- mode. The original source file is written in Emacs Lisp and is available in the etcdirec‐ tory of the distribution. This file should be installed according to the current Emacs installation.


This chapter contains additional notes for the package maintainer. They are also useful for anybody who is in charge of integrating the distribution in a build process. The chap‐ ter describes the distribution tree with more details. The distribution tree The distribution tree is composed of various directories. Each of them has a Makefilewhich can be called locally or from the top level. cnf This directory contains the configuration distribution and various utilities. Nor‐ mally you should not touch it, unless you are using a compiler different than gcc. src This directory contains the complete source tree. The source code is written in C++. Normally this directory is left untouched. If there are good reasons to modify it, please contact the development team. tst This directory contains the complete test suites. The test suites are used by vari‐ ous programs including the main interpreter, the compiler and the debugger. It shall be noted that the library distribution also includes specific test suites. doc This directory contains the complete documentation written in in XML with a special DTD. It should be left untouched. etc This directory contains various files associated with the distribution. Some files are useful to be copied. exp This directory contains various examples. They are included for illustration pur‐ pose. The process of building a package solely depends on the distribution type. Most likely, the standard distribution should contain the binary executables as well as some configura‐ tion file and the manual pages. The documentation and the development header files can put in separate packages. Configuration and setup The configuration process involves the use of the afnix-setupcommand located in the cnf/bindirectory. This command is used to configure the distribution. Package maintainers are encouraged to use it with specific options. Platform detection The afnix-guesscommand is used during the configuration process to detect a supported platform. This command can be run in stand-alone mode. Various options can be used to tune the type of information requested. Option Description -h Print a help message -n Print the platform name -v Print the platform version -M Print the platform major number -m Print the platform minor number -p Print the platform patch number -t Print the processor type Without option, the utility prints a platform and processor description string. zsh> ./cnf/bin/afnix-guess linux-4.7-x64-generic Platform defaults The directory cnf/defcontains a platform specific default file. The file determines what is the default compiler and linking mode. This file is used by the afnix-setupcommand. For example, the afnix-darwin.deffile contains: compiler: gcc lktype : dynamic lkmode : dylib Such options instructs the configuration utility, that the default compiler is gccand the linking mode should operates in dynamic mode by using the dylibrule. These default values can be overwritten with the equivalent option of the afnix-setupcommand. Note that the compiler version is automatically detected by the system. The afnix-vcompcommand will return the appropriate compiler version running on the target system. C++ source file conventions THe source tree has two types of C++ files. The first type has the extension .cxxand the second type has the extension .cpp. The .cxx-- and the associated .hxx-- files are only used to indicate a system dependency. These files are found only in the src/lib/pltdirec‐ tory. The .cxxextension indicates that the file might use system specific include files. The .cpp-- and the associated .hpp-- files are the normal C++ source files. The .cppexten‐ sion is used to indicate that these files will not use a system specific file. By default this rule is enforced in the compiler configuration file by specifying some compiler flags which do not authorize such access. Configuration files The configurations files are located in the cnf/makdirectory. Normally they should be left untouched. The most important one is the afnix-rule.makfile that defines most of the com‐ pilation and linking rules. Additionally, during the setup operation, the afnix-setupcom‐ mand creates several files in the bld/cnfdirectory. The bldis the build directory. The afnix-plat.makfile is the platform configuration file and the afnix-comp.makis a link to the appropriate compiler configuration file. Compilation Normally, the compilation process is immediate. Just invoking the makecommand will do the job. However, some package maintainer have the desire to overwrite some flags. Some options are provided to facilitate this task. EXTCPPFLAGS This flag can be used to add some compilation flags for all .cppfiles. EXTCXXFLAGS This flag can be used to add some compilation flags for all .cxxfiles. EXTCCDEFINE This flag can be used to add some compilation definitions for all source files. EXTINCLUDES This flag can be used to add some compilation paths for the .cxxfiles. For example, it is common to have some maintainer to compile with both the debug and opti‐ mize flags. This can be done with the following command (assuming an optimized configura‐ tion): make EXTCPPFLAGS=-g EXTCXXFLAGS=-g All include files, compiled libraries and executables are placed in the blddirectory. This directory contains the bld/binfor binaries, bld/libfor libraries and bld/hdrfor the header files. Building the package The package can be built by accessing the blddirectory or by invoking the installrule. The second method is not recommended for package construction, since it might trigger some file installation without any control. The etcdirectory contains some special files that might be used for the package construction. A sample list of them is given hereafter. afnix-mode.el This file is the Emacs mode. afnix-gud.el This file is the debugger Emacs gud mode. Specific makefile rules The top level Makefilecontains several rules that might be useful for the package main‐ tainer. status This rule show the configuration status for each parameters with the version. debug This rule invokes the default configuration in debug mode. optimized This rule invokes the default configuration in optimized mode. build This rule invokes the default configuration in debug mode and compile the whole distribution. The default install directory is /usr/local. world This rule invokes the default configuration in optimized mode and compile the whole distribution. The default install directory is /usr/local. test This rule runs all test suites. doc This rule builds the documentation. distri This rule builds the distribution. install This rule installs the distribution. publish This rule installs the documentation. clean This rule cleans the distribution but keep the configuration. reset This rule resets the distribution including the configuration.


This chapter contains the release notes for the differents releases. Release notes are given in descending order for a particular version. The standard notation is major.minor.patchwhich represents respectively, the major, minor and patch number. A major version number changes indicates a substantial change in the distribution, including new tools, application interface and license. A minor version number change indicates notice‐ able change, with or without new tools but without application interface change nor license change. Finally, a patch number change indicates a simple change to fix problem. There is no additional features in a patch nor an application interface change.

Release history 09/01/2008: release 1.7.1 AFNIX 1.7.1, the « An Armor release » has been released. This is an emergency release that corrects a major problem within the evaluation process. Although, the problem has been fixed, it involves a large piece of code, with a major redesign of the evaluation engine. It is therefore recommended to upgrade the engine immedi‐ ately. 08/08/2008: release 1.7.0 AFNIX 1.7.0, the « An Armor release » has been released. This is a major release that incorporates numerous new features in the field of cryptography. The release also incorporates the latest 5.1.0 Unicode database. Release 1.6 Release features Core engine: object collection redesign The core engine has been seriously modified to accommodate for a new object collec‐ tion system (aka garbage collection). The new system is more robust and provides new mechanism that will permit to reclaim cyclic structure as well as destroying global object on demand. Core engine: macos x support The core engine has been adapted to support the new MACOS X Leopard operating sys‐ tem. Release history 01/01/2008: release 1.6.0 AFNIX 1.6.0 has been released. This release provides is an intermediate candidate toward another major release. The most important thing is that the object collec‐ tion engine has been redesigned and that MACOS X Leopard is now supported. Release 1.5 Release features Core engine: unicode 5.0 support The core engine continues to be updated in order to better support the Unicode 5.0 standard. With this release, the string normalization scheme is now in place and used by default internally. This implies among other things, a better support for multiple diacritics as well as the beginning of the standard collation algorithm. Core engine: log file support The Loggerbase class has been enhanced to support the generation of a log file. An output stream can now be bound to the object. Core engine: class defer support The concept of class deferobject has been added to the Classobject. The defermode is the opposite of the infermode and provides a mechanism for base class creation. Core engine: print table header The PrintTableobject has been enhanced to support the concept of table header. Core engine: exception re-throwing The exception object whatcan be thrown with the reserved keyword throw. This pro‐ vides a mechanism to re-throw an exception. Core engine: critical bug with return form A critical bug in the core engine affecting the behavior of the returnreserved key‐ word in a tryblock has been fixed. A return form inside a try block was incorrectly generating an exception which was subsequently caught by the try block. Core modules: net module The base network module has been enhanced to better operate with IPV6. In particu‐ lar, when both IPV4 and IPV6 stacks are present and a host name (typically local‐ host) have an address entry, the socket constructor make sure it can build an object. The IPV6 address display has been rewritten. Core modules: sio module A new object called Pathnamehas been added to support the manipulation of system path. In addition, two new functions mkdirand mhdirhave been also added to support the directory creation, both normally and hierarchically. Core modules: nwg module The Urihas been dramatically enhanced to conform to the RFC 3986. In particular, the path representation for urn is now working properly. The cookie object has been massaged to support the cookie version 1, although it does not seem to be supported (yet!) by the browsers. Core modules: xml module The xml module has been enhanced with a new parsing system called the simple model. In the simple model, nodes are parsed in a linear fashion. The node content is available in the form of a string and its interpretation is at the user discretion. Core service: wax service The afnix-wamservice has been renamed as afnix-wax. The service has also been updated with two new objects, namely the XmlMimeand XhtmlMimewhich permits to build a mime representation of an xml tree. Several xhtml objects have also been added to complete the collection. This include the XhtmlScriptfor example. Core service: xpe service The afnix-xpeservice has been added as a new service. The xml processing environ‐ ment (xpe) provides a xml processor that permits manipulate the whole xml tree with the help of various xml processor features. In particular, the service provides the support for the xml include extension. Core projects: apx project This release incorporates for the first time, the concept of core project, which represents a librarian or an application. The first project is the AFNIX protocol extension or apxwhich is a message based protocol designed to transport request/reply messages within a client/server environment. The message is built with the xml library and the librarian provides the encapsulation layer. Core projects: amd project The AFNIX media dumper or amdproject is a complete application designed to illus‐ trate the design of an application. The application permits to dump an uri content into a file. Release history 06/08/2007: release 1.5.2 AFNIX 1.5.2 has been released. This is a minor release that fixes the build process with GCC 4.2. 04/21/2007: release 1.5.1 AFNIX 1.5.1 has been released. This is a minor release that fixes the documentation targets during the build process. 04/18/2007: release 1.5.0 AFNIX 1.5.0 has been released. This release provides a xml processor in the form of a new service module called 'xml processing environment' or xpe. The whole documen‐ tation generation is now fully automated, thanks to the new xml processor. This release also provides a better support for the 'web application extension' or wax service. The support for the GNU/FreeBSD platform has also been added in this release. As usual, this release comes with its wagon of bug fixes, notably this time in the network field especially with IPV6 on the FreeBSD platform. Release 1.4 Release features Core engine: unicode 5.0 support The core engine has been substantially changed to support the new Unicode 5.0 stan‐ dard. As of now, the engine is in place internally, but not fully activated. In particular, the string normalization is implemented but not activated. The next release should incorporate the full system with a change that should be transparent to the user. Core language: instance inference An instance inference mechanism -- which is equivalent to the concept of virtual constructor -- has been added to the core engine. Such system permits to derive top instance from a base instance construction. Core language: print table object The PrintTableobject has been enhanced with a dumpmethod similar to the format‐ method. Core language: property list object The Propertyand the Plistobjects have been added to the standard library. a prop‐ erty is name/value pair. The property list object is an iterable object that stores property objects. Core modules: xml module A new module called afnix-xmlhas been added. The module provides the foundation for a full xml 1.0/1.1 support. The module also includes a parser that permits to build xml tree. A xml tree writer is also part of the module functionality. A xml proces‐ sor is not yet available and is expected in the next release. Core modules: nwg module A new module called afnix-nwghas been added. The module provides the support for the network working groupobjects such like Uriobject. The module also provides the foundation for the mime support. Core modules: web module The afnix-webmodule has been removed and replaced by the afnix-wamservice. Core service: wam service The afnix-wamservice has been added as the first service into the core distribu‐ tion. A service differs from a module in the sense that it is a combination of dif‐ ferent modules. The web application managementservice depends on the xml and nwg modules. The service provides all the functionality to support a http session, including xhtml page generation and cgi request reply. Release history 01/28/2007: release 1.4.3 This release is a minor release that fixes the "install" rule in the etc directory. 01/01/2007: release 1.4.2 This release is a minor release that fixes the tcp socket read method that incor‐ rectly handles a connection reset by the peer. The Timeclass also incorporates a small fix for the to-rfcmethod. 11/09/2006: release 1.4.1 This release is a minor release that fixes the lexer for not parsing correctly some floating point numbers. The standard i/o documentation is also fixed. A print media support is now available in the documentation. 11/06/2006: release 1.4.0 This release incorporates the Unicode 5.0 standard as well as a brand new xml mod‐ ule. This release also introduces the concept of service module, which provides additional functionalities on top of regular modules. A new service module called web application managementor wamis also introduced with this release. This service module is based on the newly created xml module and replaces the old web module which has been obsoleted immediately. Release 1.3 Release features Core language: ISO-8859 transcoding support The core engine has been modified to integrate a character transcoder that permits the support all ISO-8859codesets which are mostly used for the encoding of european and arabic characters. Depending on the locale settings, the transcoder automati‐ cally remaps the 8 bits characters into their respective unicode character. All clients have been updated to detect their associated locale and to set automati‐ cally the appropriate transcoder. A new option -ehas been added to force a particu‐ lar encoding. Core language: Logger base class A logging base class has been added. The logging facility provides the interface to store messages by time and level. This class is further extended in the modules. Core language: Heap class A heap class has been added. The heap can operate in ascending or descending mode. This class can be used to support priority queue. Core language: Option class An option class has been added in order to ease the option capture when designing an application. The class permits to define the valid options and offer a powerful retrieval mechanism. Core language: Date class The Timeclass has been completely changed and a new Dateclass has been added. The new mechanism provides a better separation between the time and the date, increase the date range and authorizes the support for multiple calendar. Client: cross spreadsheet client The axsclient has been modified to support the axs:insert-marker, axs:insert- headerand insert-footercontrol commands. Core modules: speadsheet module The Folioand Sheetclasses have been substantially updated to support additional information. The Sheetalso supports the concept of markers that marks the sheet columns by literals. The concept of column tagging has been added with the associ‐ ated search methods. All classes also contain an information field. The importation mechanism now supports a cons cell that defines both the cell name and the cell value. Core modules: web module The Tableclass has been modified to support the concept of table data header. The associated methods have been added to the class and a new HtmlThhas been added. The concept of tag propagation has also been added. If a tag element already exists, this one is not added. This is particularly true for the classtag that is now part of the class constructor. The HtmlPageclass has been put in strict conformance with xhtml 1.1 and the XHtmlpageclass has been removed. Core modules: pim module A new module called the afnix-pimmodule has been added to the base distribution. The personal information management or pimmodule is designed to ease the management of personal information and agenda. Core modules: gfx module A new module called the afnix-gfxmodule has been added to the base distribution. The module contains the base class that supports the graph data structure which was previously part of the standard library. Release 1.2 Release features Core language: Unicode support The core engine has been substantially modified to integrate the support for Uni‐ code characters. Depending on the system settings the reader automatically adjust itself to operate in byte mode or in UTF-8 mode. The Stringand Characterclasses are now operating with a Unicode representation. The design of an Unicode based engine also impacts several classes like the Regex, Bufferand stream classes. A new class called Byteis also designed to handle byte character. A new stream model with a base Streamclass has also been added. The full support with Unicode character is not yet completed. In particular, certain codesets are not supported at all. This is particularly true with case-conversion functions. Core language: orphan instance and reparenting The object model now supports the creation of orphan instancewhich is an instance without a class attached to it. The instance can be later bound to a class and such class can even be changed during the course of the program execution. Core modules: network module The Addressclass has been updated to reflect the access to address aliases. Core modules: text processing module The Literateclass has been updated to reflect the support of Unicode characters. The class can operate both in byte mode or in Unicode character mode. Release 1.1 Release features Core language: Large file support Support for the large file system has been added in the base distribution. All input/output operations as long as they are supported by the operating system are now done in 64 bits mode. Core libraries: Secure hash algorithm The cryptographic library incorporates the support for the SHA-1, SHA-256, SHA-384 and SHA-512 hash algorithms. Core libraries: Standard symmetric cipher The cryptographic library incorporates the support for the Advanced Encryption Standard (AES) as a symmetric cipher. Core libraries: ODC library renamed The ODC library has been renamed to SPS which stands for spreadsheet library. This new name is considered more appropriate for the function the library achieves. Core libraries: xhtml 1.1 support The XhtmlPara class is now configured to support XHTML 1.1 with utf-8 encoding. Documentation: XML based documentation The documentation has been rewritten completely in XML. A DTD as well as the neces‐ sary XSLT style sheets have also been designed to produce a professional documenta‐ tion which can be used for printing or for online browsing.
