%general-entities; ]> $LastChangedBy$ $Date$ Perl modules The Perl module packages add useful objects to the Perl language. Modules utilized by packages throughout BLFS are listed here, along with their dependencies. Installation of the modules shown on this page should be accomplished by installing the dependencies in the order listed. The Perl Module standard build and installation instructions are shown at the bottom of this page. Where a module is shown as '(for the testsuite)' it is required if you wish to run the test for the module which uses it. In these cases, only the required dependencies are listed - there might be other modules which allow more tests to be run, but omitting them will still allow the tests to PASS.

A Uniform Resource Identifier is a compact string of characters that identifies an abstract or physical resource. A Uniform Resource Identifier can be further classified as either a Uniform Resource Locator (URL) or a Uniform Resource Name (URN).

This module uses the standard . &lfs78_checked; XML::Writer-&XML-Writer-version; &XML-Writer-download-http; MD5 sum: &XML-Writer-md5sum; Install Perl modules by running the following commands: perl Makefile.PL && make && make test Now, as the root user: make install When reinstalling a Perl module, sometimes older versions of the module being reinstalled are in other directories specified in @INC. To delete all other versions of the module being reinstalled (not simply older ones) set the UNINST variable: make install UNINST=1 Before perl-5.22, Module::Build was part of the core distribution. Now it must be installed separately (see above) before any of the modules which use it can be built. Install Perl modules which use Build.PL by running the following commands: perl Build.PL && ./Build && ./Build test Now, as the root user: ./Build install There is an alternate way of installing the modules using the cpan shell install command. The command automatically downloads the source from the CPAN archive, extracts it, runs the compilation, testing and installation commands mentioned above, and removes the build source tree. You may still need to install dependent library packages before running the automated installation method. The first time you run cpan, you'll be prompted to enter some information regarding download locations and methods. This information is retained in files located in ~/.cpan. Start the cpan shell by issuing 'cpan' as the root user. Any module may now be installed from the cpan>  prompt with the command: install <Module::Name> For additional commands and help, issue 'help' from the cpan>  prompt. Alternatively, for scripted or non-interactive installations, use the following syntax as the root user to install one or more modules: cpan -i <Module1::Name> <Module2::Name> Review the cpan.1 man page for additional parameters you can pass to cpan on the command line. Most of these modules only install into the perl directories, but a few will also install programs (mostly, perl scripts), or even a library, into /usr Installed Programs Installed Libraries Archive::Zip: crc32 File::Find::Rule: findrule libwww-perl: lwp-download, lwp-dump, lwp-mirror, lwp-request Log::Log4perl: l4p-tmpl Module::Build config_data Pod::Coverage: pod_cover Text::BibTeX: biblex, bibparse, dumpnames Text::BibTeX: libbtparse.so Short Descriptions crc32 computes and prints to stdout the CRC-32 values of the given files. crc32 findrule is a command line wrapper to File:Find:Rule. findrule lwp-download is a script to fetch a large file from the web. lwp-download lwp-dump is used to see what headers and content is returned for a URL. lwp-dump lwp-mirror is a simple mirror utility. lwp-mirror lwp-request is a simple command line user agent. lwp-request l4p-templ prints out the text of a template Log4perl configuration for starting a new Log4perl configuration file. l4p-templ config_data is used to query or change the configuration of perl modules. config_data pod_cover is used to get a coverage analysis of the embedded documentation in a perl module. pod_cover biblex performs lexical analysis on a BibTeX file. biblex bibparse parses a series of BibTeX files with command line options to control the string post-processing behaviour. bibparse dumpnames parses a BibTeX file, splitting 'author' and 'editor' fields into lists of names, and then dumps everything to stdout. dumpnames libbtparse.so is a library for parsing and processing BibTeX data files. libbtparse.so
