Module::Install::RTx(3pm)

Usage

In the Makefile.PL of the "RT-Extension-Example" module:

    use inc::Module::Install;
    RTx 'RT-Extension-Example';
    requires_rt '5.0.0';
    rt_too_new  '6.0.0';
    WriteAll();

Overview

This Module::Install extension implements several functions for installing RT extensions:

RTx 'extension name'

This function arranges for the following directories to be installed, if they exist (assuming RTx('RT-Extension-Example')):

    ./bin    => $RT::LocalPluginPath/RT-Extension-Example/bin
    ./etc    => $RT::LocalPluginPath/RT-Extension-Example/etc
    ./html   => $RT::LocalPluginPath/RT-Extension-Example/html
    ./lib    => $RT::LocalPluginPath/RT-Extension-Example/lib
    ./po     => $RT::LocalPluginPath/RT-Extension-Example/po
    ./sbin   => $RT::LocalPluginPath/RT-Extension-Example/sbin
    ./static => $RT::LocalPluginPath/RT-Extension-Example/static
    ./var    => $RT::LocalPluginPath/RT-Extension-Example/var

Accepts an optional argument hashref after the extension name with two possible keys

deprecated_rt

    If set to a true value, skips the enforced RT-4.0.0 minimum version check
    You should set a perl_version if using this option and requires_rt(), because requires_rt
    only handles figuring our what perl you need if you're on RT 4.0.0 or higher.

no_readme_generation

    If set to a true value, will not call readme_from on the extension's primary perl module.

requires_rt version

Takes one argument, a valid RT version. If an attempt is made to install on an RT than that version, it will die before Makefile creation.

requires_rt_plugin RT::Extension::Example [, version]

Ensures that the given RT extension (and optional version) is installed in the target RT instance; "requires" cannot be used because RT extensions are not in @INC.

rt_too_new version [, message]

Takes one argument, a valid RT version, and prevents this module from being installed on any version of RT equal to or newer than that. Useful if a particular release of an extension only works on 4.0.x but not 4.2.x.

Takes an optional second argument which allows you to specify a custom error message. This message is passed to sprintf with two string arguments, the current RT version and the version you specify.

remove_files

If set to a true value, during installation any files listed in a "remove_files" file will be removed from the destination directories. This feature is for removing files that have been deleted or moved in the current version and leaving the old version in place when upgrading can cause problems.

RTx looks for a "remove_files" file in the etc/upgrade directory of the distribution. The format of the "remove_files" file is as follows:

    package Module::Install::RTx;
    @remove_files = qw(
    html/dir/file_to_remove
    );
    1;

The file locations are relative to the distribution. The destination directory prefix is added automatically.

Caveats

•: Us the full name when calling RTx method in Makefile.PL; while RTx('Foo') was once supported, it is no longer.

Environment

RTHOME: Path to the RT installation that contains a valid lib/RT.pm.

Examples

To install an extension which makes use of this installer:

    perl Makefile.PL RTHOME=/opt/rt6

This will install all subdirs into the $RT::LocalPluginPath dir as configured in RT::Generated.

To install an extension into the (vendor) plugin path:

    perl Makefile.PL RTHOME=/opt/rt6 INSTALLDIRS=vendor

This will install all subdirs into the $RT::PluginPath which is specifically meant for plugins that are installed through other packaging utils like APT or RPM.
