man Dist::Zilla::Plugin::TemplateCJM (3): Process templates, including version numbers & changes

VERSION

This document describes version 4.09 of Dist::Zilla::Plugin::TemplateCJM, released June 4, 2012 as part of Dist-Zilla-Plugins-CJM version 4.09.

SYNOPSIS

In your dist.ini:

[TemplateCJM]
changelog = Changes ; this is the default
changes = 1 ; this is the default
file = README ; this is the default
report_versions = 1 ; this is the default

DESCRIPTION

This plugin is the successor to Module::Build::DistVersion. It performs the following actions:

1.

It opens the Changes file, and finds the first version listed. The line must begin with the version number, and everything after the version number is considered to be the release date. The version number from Changes must match Dist::Zilla's idea of the distribution version, or the process stops here with an error.

2.

It processes each template file with Text::Template. Template files are specified with the "file" attribute. Any number of templates may be present.

Each template may use the following variables:

$changes: The changes in the current release. This is a string containing all lines in Changes following the version/release date line up to (but not including) the next line that begins with a non-whitespace character (or end-of-file). The string does not end with a newline (since version 0.08).
You can include the changes from more than one release by setting the ``changes'' in "changes" attribute. This is useful when you make a major release immediately followed by a bugfix release.
$date: The release date as it appeared in Changes.
$dist: The name of the distribution.
%meta: The hash of metadata that will be stored in META.yml.
$t: The TemplateCJM object that is processing the template.
$version: The distribution's version number. (Also available as $dist_version.)
$zilla: The Dist::Zilla object that is creating the distribution.

3.

For each module to be installed, it processes each POD section and each comment that starts at the beginning of a line through Text::Template.

Each section may use the same variables as step 2, plus the following:

$module: The name of the module being processed (i.e., its package).
$pm_info: A Module::Metadata object containing information about the module. (Note that the filename in $pm_info will not be correct.)
$version: The module's version number. This may be different than the distribution's version, which is available as $dist_version.

It also peforms a BeforeRelease check to ensure that the release date in the changelog is not a single uppercase word. (I set the date to NOT until I'm ready to release.)

ATTRIBUTES

changelog

This is the name of the Changes file. It defaults to Changes.

changelog_re

This is the regex used to extract the version and release date from the Changes file. It defaults to "(\d[\d._]*)\s+(.+)" (i.e. version number at beginning of the line, followed by whitespace, and everything after that is the release date). It it automatically anchored at the beginning of the line. Note: your version lines must not begin with whitespace. All other lines must begin with whitespace.

changes

This is the number of releases to include in the $changes variable passed to templates. It defaults to 1 (meaning only changes in the current release). This is useful when you make a major release immediately followed by a bugfix release.

file

This is the name of a file to process with Text::Template in step 2. The "file" attribute may be listed any number of times. If you don't list any "file"s, it defaults to README. If you do specify any "file"s, then README is not processed unless explicitly specified.

finder

This FileFinder provides the list of files that are processed in step 3. The default is ":InstallModules". The "finder" attribute may be listed any number of times.

report_versions

If true (the default), report the version of each module processed.

METHODS

build_instructions

  $t->build_instructions( [$prefix] )

A template can use this method to add build instructions for the distribution (normally used in README). $prefix is prepended to each line, and defaults to a single TAB.

It returns either

        perl Build.PL
        ./Build
        ./Build test
        ./Build install

        perl Makefile.PL
        make
        make test
        make install

depending on whether your distribution includes a Build.PL. The string will NOT end with a newline.

It throws an error if neither Build.PL nor Makefile.PL is found.

dependency_link

  $t->dependency_link('Foo::Bar')

A template can use this method to add a link to the documentation of a required module. It returns either

  L<Foo::Bar> (VERSION or later)

  L<Foo::Bar>

depending on whether VERSION is non-zero. (It determines VERSION by checking "requires" and "recommends" in your prerequisites.)

dependency_list

  $t->dependency_list

A template can use this method to add a list of required modules. It returns a string like:

  Package                Minimum Version
  ---------------------- ---------------
  perl                    5.8.0
  List::Util
  Moose                   0.90

If "perl" is one of he dependencies, it is listed first. All other dependencies are listed in ASCIIbetical order. The string will NOT end with a newline.

If there are no dependencies, the string "None." will be returned.

DEPENDENCIES

TemplateCJM requires Dist::Zilla (4.300009 or later) and Text::Template. I also recommend applying Template_strict.patch to Text::Template. This will add support for the STRICT option, which will help catch errors in your templates.

INCOMPATIBILITIES

None reported.

BUGS AND LIMITATIONS
